PowerShares Wilderhill Clean Energy Portfolio (Prospectus Summary) | PowerShares Wilderhill Clean Energy Portfolio
Risk/Return:	rr_RiskReturnAbstract
Risk/Return, Heading	rr_RiskReturnHeading	PowerShares WilderHill Clean Energy Portfolio
Investment Objective, Heading	rr_ObjectiveHeading	Investment Objective
investment Objective, Primary	rr_ObjectivePrimaryTextBlock	The PowerShares WilderHill Clean Energy Portfolio (the "Fund") seeks investment results that generally correspond (before fees and expenses) to the price and yield of the WilderHill Clean Energy Index (the "Underlying Index").
Expense, Heading	rr_ExpenseHeading	Fund Fees and Expenses
Expense, Narrative	rr_ExpenseNarrativeTextBlock	This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund ("Shares"). Investors may pay brokerage commissions on their purchases and sales of Shares, which are not reflected in the table or the example below.
Operating Expenses, Caption	rr_OperatingExpensesCaption	Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)
Portfolio Turnover, Heading	rr_PortfolioTurnoverHeading	Portfolio Turnover
Portfolio Turnover	rr_PortfolioTurnoverTextBlock	The Fund pays transaction costs, such as commissions, when it purchases and sells securities (or "turns over" its portfolio). A higher portfolio turnover will cause the Fund to incur additional transaction costs and may result in higher taxes when Fund Shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the example, may affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover was 32% of the average value of its portfolio.
Portfolio Turnover, Rate	rr_PortfolioTurnoverRate	32.00%
Expense, Exchange Traded Fund, Commissions	rr_ExpenseExchangeTradedFundCommissions	Investors may pay brokerage commissions on their purchases and sales of Shares, which are not reflected in the table or the example below.
Expense Example, Heading	rr_ExpenseExampleHeading	Example
Expense Example, Narrative	rr_ExpenseExampleNarrativeTextBlock	This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. This example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your Shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The cost under the one year example is equal to the Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the first year and the Total Annual Fund Operating Expenses thereafter. This example does not include the brokerage commissions that investors may pay to buy and sell Shares of the Fund.
Expense Example, By Year, Caption	rr_ExpenseExampleByYearCaption	Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:
Investment Strategy, Heading	rr_StrategyHeading	Principal Investment Strategies
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 80% of its total assets in common stocks of companies engaged in the business of the advancement of cleaner energy and conservation. The Fund generally will invest at least 90% of its total assets in common stocks that comprise the Underlying Index. As of the date of this Prospectus, the Underlying Index was composed of the stocks of approximately 56 companies that are publicly traded in the United States, which the Underlying Index Selection Committee believes will substantially benefit from a societal transition toward the use of cleaner energy and conservation. Strictly in accordance with its existing guidelines and mandated procedures, the Underlying Index's Selection Committee includes stocks based on expert evaluation. At its discretion, the Selection Committee reviews the Underlying Index's components stocks quarterly or more often. As of the date of this Prospectus, the Underlying Index included common stocks of companies with a market capitalization range of between approximately $44 million and $16 billion. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.

The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. Clean Energy Industry Concentration Risk. Obsolescence of existing technology, short product cycles, falling prices and profits, competition from new market entrants and general economic conditions can significantly affect the clean energy industry. Additionally, intense competition and legislation resulting in more strict government regulations and enforcement policies and specific expenditures for cleanup efforts can significantly affect the clean energy industry. The clean energy industry also is subject to risks associated with hazardous materials. Fluctuations in energy prices and supply and demand of alternative energy fuels, energy conservation, the success of exploration projects and tax and other government regulations significantly affect the clean energy industry. In addition, supply and demand for specific products or services, the supply and demand for oil and gas, the price of oil and gas, production spending, government regulation, world events and economic conditions can affect the industry. Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Index is comprised of issuers in a single industry or sector of the economy. By focusing in an industry or sector, the Fund faces more risks than if it were diversified broadly over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries or the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Index resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming. Small and Medium Capitalization Company Risk. Investing in securities of small and medium capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Often small and medium capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund's volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund's performance. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC or any other government agency.
Risk, Lose Money	rr_RiskLoseMoney	The Shares will change in value, and you could lose money by investing in the Fund.
Risk, Nondiversified Status	rr_RiskNondiversifiedStatus	The Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund's volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund's performance.

Bar Chart and Performance Table, Heading	rr_BarChartAndPerformanceTableHeading	Performance
Performance, Narrative	rr_PerformanceNarrativeTextBlock	The bar chart below shows how the Fund has performed. The table below the bar chart shows the Fund's average annual total returns (before and after taxes). The bar chart and table provide an indication of the risks of investing in the Fund by showing how the Fund's total return has varied from year to year and by showing how the Fund's average annual total returns compared with a broad measure of market performance. The Fund's performance reflects fee waivers, if any, absent which, performance would have been lower. Although the information shown in the bar chart and the table gives you some idea of the risks involved in investing in the Fund, the Fund's past performance (before and after taxes) is not necessarily indicative of how the Fund will perform in the future.

Performance Table, Not Relevant to Tax Deferred	rr_PerformanceTableNotRelevantToTaxDeferred	Actual after-tax returns depend on an investor's tax situation and may differ from those shown, and after-tax returns shown are not relevant to investors who hold Shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.
Performance Table, Narrative	rr_PerformanceTableNarrativeTextBlock	After-tax returns in the table below are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown, and after-tax returns shown are not relevant to investors who hold Shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. In the event of negative performance displayed in the table below, the Fund's returns after taxes on distributions and sale of Fund Shares are calculated assuming that an investor has sufficient capital gains of the same character from other investments to offset any capital losses from the sale of Fund Shares so that the investor may deduct the losses in full. As a result, the Fund's returns after taxes on distributions and sale of Fund Shares may exceed the Fund's returns before taxes and/or returns after taxes on distributions.

[1] Invesco PowerShares Capital Management LLC (the "Adviser") has agreed to waive fees and/or pay Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, brokerage commissions and other trading expenses, sub-licensing fees, offering costs, taxes and extraordinary expenses) from exceeding 0.60% of the Fund's average daily net assets per year (the "Expense Cap") until at least August 31, 2012, and neither the Adviser nor the Fund can discontinue the agreement prior to its expiration. The expenses borne by the Adviser are subject to recapture by the Adviser for up to three years from the date the fee or expense was borne by the Adviser, but no recapture payment will be made by the Fund if it would result in the Fund exceeding its Expense Cap.

Investment Strategy, Heading	rr_StrategyHeading	Principal Investment Strategies
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 90% of its total assets in the component securities that comprise the Underlying Index. The Underlying Index is comprised of common stocks of "large growth" U.S. companies (including real estate investment trusts ("REITs")) that Research Affiliates, LLC ("RAFI Affiliates" or the "Index Provider") classifies based on its Fundamental Index® methodology. Strictly in accordance with its existing guidelines and mandated procedures, the Index Provider identifies the common stocks for inclusion in the Underlying Index from a universe of the 2,500 largest U.S. companies. The use of the word "Fundamental" in the Fund's name reflects the fact that, in identifying the common stocks, the Index Provider uses fundamental measures of company size rather than market capitalization (company share price multiplied by number of shares outstanding). The Index Provider uses the following fundamental measures to include common stocks in the Underlying Index: book value, income, sales and dividends. The Index Provider calculates a composite fundamental weight for each common stock by equally weighting the above four fundamental measures. The Index Provider ranks each common stock by its fundamental weight and, based on this ranking, divides the common stocks into three size groups: "large," "mid" and "small." The common stocks it ranks in the top 70% of the eligible universe by fundamental weight comprise the "large" size group, the next 20% comprise the "mid" size group, and the final 10% comprise the "small" size group. The Index Provider divides the "large" size group further into "growth," "core" or "value" subsets based on the Fundamental Index® methodology style score, which uses a combination of fundamental growth rates and fundamental valuation ratios. The Underlying Index is composed only of those common stocks that the Index Provider classifies as both "large" and "growth." The Fund generally will invest at least 80% of its total assets in common stocks of "fundamentally large" companies. The Fund considers "fundamentally large" companies to be those companies that comprise the Underlying Index. The use of the word "Pure" in the Fund's name reflects that, in selecting securities for the Underlying Index, the Index Provider includes only those securities that it has classified as "growth." Although "growth" funds also could include some stocks that, based on their classification, would be considered "core" or "value," the Underlying Index contains only those stocks that the Index Provider classifies as pure "growth" stocks. The Fund generally will invest in all of the securities comprising its Underlying Index in proportion to their weightings in the Underlying Index. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its net assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.

Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. "Fundamentally Large" Company Risk. Returns on investments in common stocks of "fundamentally large" U.S. companies could trail the returns on investments in common stocks of smaller companies or other large companies based on market capitalization. Growth Risk. The market values of "growth" securities may be more volatile than other types of investments. The returns on "growth" securities may or may not move in tandem with the returns on other styles of investing or the overall stock market. Thus, the value of the Fund's investments will vary and at times may be lower or higher than that of other types of investments. REIT Risk. Although the Fund will not invest in real estate directly, the REITs in which the Fund invests are subject to risks inherent in the direct ownership of real estate. These risks include, but are not limited to, a possible lack of mortgage funds and associated interest rate risks, overbuilding, property vacancies, increases in property taxes and operating expenses, changes in zoning laws, losses due to environmental damages and changes in neighborhood values and appeal to purchasers. Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Index may be comprised of issuers in a single industry or sector of the economy. If the Fund is focused in an industry or sector, it may present more risks than if it were broadly diversified over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries of the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Index resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming. Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund's volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund's performance. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Investment Strategy, Heading	rr_StrategyHeading	Principal Investment Strategies
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 90% of its total assets in the component securities that comprise the Underlying Index. The Underlying Index is comprised of common stocks of "mid growth" U.S. companies (including real estate investment trusts ("REITs")) that Research Affiliates, LLC ("RAFI Affiliates" or the "Index Provider") classifies based on its Fundamental Index® methodology. Strictly in accordance with its existing guidelines and mandated procedures, the Index Provider identifies the common stocks for inclusion in the Underlying Index from a universe of the 2,500 largest U.S. companies. The use of the word "Fundamental" in the Fund's name reflects the fact that, in identifying the common stocks, the Index Provider uses fundamental measures of company size, rather than market capitalization (company share price multiplied by number of shares outstanding). The Index Provider uses the following fundamental measures to include common stocks in the Underlying Index: book value, income, sales and dividends. It then calculates a composite fundamental weight for each common stock by equally weighting the above four fundamental measures. The Index Provider then ranks each common stock by its fundamental weight and, based on this ranking, divides the common stocks into three size groups: "large," "mid" and "small." The common stocks it ranks in the top 70% of the eligible universe by fundamental weight comprise the "large" size group, the next 20% comprise the "mid" size group, and the final 10% comprise the "small" size group. The Index Provider further divides the "mid" size group into "growth," "core" or "value" subsets based on the Fundamental Index® methodology style score, which uses a combination of fundamental growth rates and fundamental valuation ratios. The Underlying Index is composed only of those common stocks that the Index Provider classifies as both "mid" and "growth." The Fund generally will invest at least 80% of its total assets in common stocks of "fundamentally mid" companies. The Fund considers "fundamentally mid" companies to be those companies that comprise the Underlying Index. The use of the word "Pure" in the Fund's name reflects that, in selecting securities for the Underlying Index, the Index Provider includes only those securities that it has classified as "growth." Although "growth" funds also could include some stocks that, based on their classification, would be considered "core" or "value," the Underlying Index contains only those stocks that the Index Provider classifies as pure "growth" stocks. The Fund generally will invest in all of the securities comprising its Underlying Index in proportion to their weightings in the Underlying Index. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Investment Strategy, Portfolio Concentration	rr_StrategyPortfolioConcentration	The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. "Fundamentally Mid" Company Risk. Investing in common stocks of "fundamentally mid" companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies' common stocks may be more volatile and less liquid than those of more established companies. These common stocks may have returns that vary, sometimes significantly, from the overall stock market. Often "fundamentally mid" companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. Growth Risk. The market values of "growth" securities may be more volatile than other types of investments. The returns on "growth" securities may or may not move in tandem with the returns on other styles of investing or the overall stock market. Thus, the value of the Fund's investments will vary and at times may be lower or higher than that of other types of investments. REIT Risk. Although the Fund will not invest in real estate directly, the REITs in which the Fund invests are subject to risks inherent in the direct ownership of real estate. These risks include, but are not limited to, a possible lack of mortgage funds and associated interest rate risks, overbuilding, property vacancies, increases in property taxes and operating expenses, changes in zoning laws, losses due to environmental damages and changes in neighborhood values and appeal to purchasers. Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Index may be comprised of issuers in a single industry or sector of the economy. If the Fund is focused in an industry or sector, it may present more risks than if it were diversified broadly over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries or the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Index resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PowerShares Dynamic Networking Portfolio (Prospectus Summary) | PowerShares Dynamic Networking Portfolio

PowerShares Dynamic Networking Portfolio

Investment Objective

The PowerShares Dynamic Networking Portfolio (the "Fund") seeks investment
results that generally correspond (before fees and expenses) to the price and
yield of the Dynamic Networking IntellidexSM Index (the "Underlying
Intellidex").

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors may pay brokerage commissions on their
purchases and sales of Shares, which are not reflected in the table or the
example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		PowerShares Dynamic Networking Portfolio
Management Fees		0.50%
Other Expenses		0.20%
Total Annual Fund Operating Expenses		0.70%
Fee Waivers and Expense Assumption	[1]	0.07%
Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption	[1]	0.63%

Example

This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. This example assumes that you invest
$10,000 in the Fund for the time periods indicated and then sell all of your
Shares at the end of those periods. The example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. The cost under the one year example is equal to the Total
Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the
first year and the Total Annual Fund Operating Expenses thereafter. This example
does not include the brokerage commissions that investors may pay to buy and
sell Shares of the Fund.

Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Expense Example (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
PowerShares Dynamic Networking Portfolio	64	217	383	864

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover rate was 61% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 80% of its total assets in common stocks
of networking companies. The Fund generally will invest at least 90% of its
total assets in common stocks that comprise the Underlying Intellidex. As of
June 30, 2011, the Underlying Intellidex was composed of stocks of 30 U.S.
networking companies. These companies are engaged principally in the
development, manufacture, sale or distribution of products, services or
technologies that support the flow of electronic information, including voice,
data, images and commercial transactions. These companies may include, for
example, providers of telecommunications and networking equipment; data storage;
systems software; internet hardware including servers; routers; switches and
related equipment; systems for data encryption and security; internet services
including hosting and commercial exchanges; fiber optics; satellites; cable
equipment and other companies involved in supporting the flow of information.
Strictly in accordance with its existing guidelines and mandated procedures, the
Intellidex Provider includes stocks principally on the basis of their capital
appreciation potential that it identifies pursuant to a proprietary Intellidex
methodology. As of June 30, 2011, the Underlying Intellidex included common
stocks of companies with a market capitalization range of between approximately
$374 million and $95 billion.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying
Intellidex reflects a concentration in that industry or group of industries. The
Fund will not otherwise concentrate its investments in securities of issuers in
any one industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Networking Industry Concentration Risk. The networking industry is evolving
rapidly and can be significantly affected by corporate capital expenditure
trends, competitive pressures such as the ability to attract and retain skilled
employees and obsolescence due to rapid technological innovation or changing
consumer preferences. Further, many network companies rely on a combination of
patents, copyrights, trademarks and trade secret laws to establish and protect
their proprietary rights in their products and technologies. There can be no
assurance that the steps taken by network companies to protect their proprietary
rights will be adequate to prevent misappropriation of their technology or that
competitors will not independently develop technologies that are substantially
equivalent or superior to such companies' technology.

Market Risk. Securities in the Underlying Intellidex are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Intellidex.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets, and disruption in the creation/redemption process of the
Fund. Any of these factors may lead to the Shares trading at a premium or
discount to the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or debt
instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Intellidex is
comprised of issuers in a single industry or sector of the economy. By focusing
in an industry or sector, the Fund faces more risks than if it were diversified
broadly over numerous industries and sectors of the economy. At times, such
industry or group of industries may be out of favor and underperform other
industries or the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Intellidex for a number of reasons. For example, the Fund incurs
operating expenses not applicable to the Underlying Intellidex, and incurs costs
in buying and selling securities, especially when rebalancing the Fund's
securities holdings to reflect changes in the composition of the Underlying
Intellidex. In addition, the performance of the Fund and the Underlying
Intellidex may vary due to asset valuation differences and differences between
the Fund's portfolio and the Underlying Intellidex resulting from legal
restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Intellidex.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Intellidex, even if that
security generally is underperforming.

Small and Medium Capitalization Company Risk. Investing in securities of small
and medium capitalization companies involves greater risk than customarily is
associated with investing in larger, more established companies. These
companies' securities may be more volatile and less liquid than those of more
established companies. These securities may have returns that vary, sometimes
significantly, from the overall securities market. Often small and medium
capitalization companies and the industries in which they focus are still evolving
and, as a result, they may be more sensitive to changing market conditions.

Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater
portion of its assets in securities of individual issuers than a diversified
fund. As a result, changes in the market value of a single investment could
cause greater fluctuations in Share price than would occur in a diversified
fund. This may increase the Fund's volatility and cause the performance of a
relatively small number of issuers to have a greater impact on the Fund's
performance.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC
or any other government agency.

Performance

The bar chart below shows how the Fund has performed. The table below the bar
chart shows the Fund's average annual total returns (before and after taxes).
The bar chart and table provide an indication of the risks of investing in the
Fund by showing how the Fund's total return has varied from year to year and by
showing how the Fund's average annual total returns compared with a broad
measure of market performance. The Fund's performance reflects fee waivers, if
any, absent which, performance would have been lower. Although the information
shown in the bar chart and the table gives you some idea of the risks involved
in investing in the Fund, the Fund's past performance (before and after taxes)
is not necessarily indicative of how the Fund will perform in the future.

[1] Invesco PowerShares Capital Management LLC (the" Adviser") has agreed to waive fees and/or pay Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, brokerage commissions and other trading expenses, sub-licensing fees, offering costs, taxes and extraordinary expenses) from exceeding 0.60% of the Fund's average daily net assets per year (the "Expense Cap") until at least August 31, 2012, and neither the Adviser nor the Fund can discontinue the agreement prior to its expiration. The expenses borne by the Adviser are subject to recapture by the Adviser for up to three years from the date the fee or expense was borne by the Adviser, but no recapture payment will be made by the Fund if it would result in the Fund exceeding its Expense Cap.

Investment Strategy, Heading	rr_StrategyHeading	Principal Investment Strategies
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 90% of its total assets in the component securities that comprise the Underlying Index. The Underlying Index is comprised of common stocks of "small value" U.S. companies (including real estate investment trusts ("REITs")) that Research Affiliates, LLC ("RAFI Affiliates" or the "Index Provider") classifies based on its Fundamental Index® methodology. Strictly in accordance with its existing guidelines and mandated procedures, the Index Provider identifies the common stocks for inclusion in the Underlying Index from a universe of the 2,500 largest U.S. companies. The use of the word "Fundamental" in the Fund's name reflects the fact that, in identifying the common stocks, the Index Provider uses fundamental measures of company size, rather than market capitalization (company share price multiplied by number of shares outstanding). The Index Provider uses the following fundamental measures to include common stocks in the Underlying Index: book value, income, sales and dividends. It then calculates a composite fundamental weight is calculated for each common stock by equally weighting the above four fundamental measures. The Index Provider then ranks each common stock by its fundamental weight and, based on this ranking, divides the common stocks into three size groups: "large," "mid" and "small." The common stocks it ranks in the top 70% of the eligible universe by fundamental weight comprise the "large" size group, the next 20% comprise the "mid" size group, and the final 10% comprise the "small" size group. The Index Provider further divides the "small" size group into "growth," "core" or "value" subsets based on the Fundamental Index® methodology style score, which uses a combination of fundamental growth rates and fundamental valuation ratios. The Underlying Index is composed only of those common stocks that the Index Provider classifies as both "small" and "value." The Fund generally will invest at least 80% of its total assets in common stocks of "fundamentally small" companies. The Fund considers "fundamentally small" companies to be those companies that comprise the Underlying Index. The use of the word "Pure" in the Fund's name reflects that, in selecting securities for the Underlying Index, the Index Provider includes only those securities that it has classified as "value." Although "value" funds also could include some stocks that, based on their classification, would be considered "growth" or "core," the Underlying Index contains only those stocks that the Index Provider classifies as pure "value" stocks. The Fund generally will invest in all of the securities comprising its Underlying Index in proportion to their weightings in the Underlying Index. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.

Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. "Fundamentally Small" Company Risk. Investing in common stocks of "fundamentally small" companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies' common stocks may be more volatile and less liquid than those of more established companies. These common stocks may have returns that vary, sometimes significantly, from the overall stock market. Often "fundamentally small" companies and the industries in which they focus are still evolving and, as a result, may be more sensitive to changing market conditions. REIT Risk. Although the Fund will not invest in real estate directly, the REITs in which the Fund invests are subject to risks inherent in the direct ownership of real estate. These risks include, but are not limited to, a possible lack of mortgage funds and associated interest rate risks, overbuilding, property vacancies, increases in property taxes and operating expenses, changes in zoning laws, losses due to environmental damages and changes in neighborhood values and appeal to purchasers. Value Risk. "Value" securities are subject to the risk that the valuations never improve or that the returns on "value" securities are less than returns on other styles of investing or the overall stock market. Thus, the value of the Fund's investments will vary and at times may be lower or higher than that of other types of investments. Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover rate was 26% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 90% of its total assets in common stocks
that comprise the Underlying Index. Strictly in accordance with its existing
guidelines and mandated procedures, Mergent®, Inc. ("Mergent" or the "Index
Provider") includes stocks in the Underlying Index pursuant to a proprietary
selection methodology. As of June 30, 2011, the Underlying Index was composed of
stocks of approximately 143 companies with a market capitalization range of
between approximately $165 million and $207 billion. To qualify for the universe
of "BuyBack AchieversTM," an issuer must have repurchased at least 5% of its
outstanding shares during the trailing 12 months.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying Index
reflects a concentration in that industry or group of industries. The Fund will
not otherwise concentrate its investments in securities of issuers in any one
industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Market Risk. Securities in the Underlying Index are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Index.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets, and disruption in the creation/redemption process of the
Fund. Any of these factors may lead to the Shares trading at a premium or
discount to the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make anticipated
dividend payments because, among other reasons, the issuer of the security
experiences a decline in its financial condition. Common stock is subordinated
to preferred stocks, bonds and other debt instruments in a company's capital
structure, in terms of priority to corporate income, and therefore will be
subject to greater dividend risk than preferred stocks or debt instruments of
such issuers.

Concentration Risk. A significant percentage of the Underlying Index may be
composed of issuers in a single industry or sector of the economy. If the Fund
is focused in an industry or sector, it may present more risks than if it were
diversified broadly over numerous industries and sectors of the economy. At
times, such industry or group of industries may be out of favor and underperform
other industries or the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Index for a number of reasons. For example, the Fund incurs operating
expenses not applicable to the Underlying Index, and incurs costs in buying and
selling securities, especially when rebalancing the Fund's securities holdings
to reflect changes in the composition of the Underlying Index. In addition, the
performance of the Fund and the Underlying Index may vary due to asset valuation
differences and differences between the Fund's portfolio and the Underlying
Index resulting from legal restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Index.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Index, even if that
security generally is underperforming.

Small and Medium Capitalization Company Risk. Investing in securities of small
and medium capitalization companies involves greater risk than customarily is
associated with investing in larger, more established companies. These
companies' securities may be more volatile and less liquid than those of more
established companies. These securities may have returns that vary, sometimes
significantly, from the overall securities market. Often small and medium
capitalization companies and the industries in which they focus are still
evolving and, as a result, they may be more sensitive to changing market
conditions.

Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater
portion of its assets in securities of individual issuers than a diversified
fund. As a result, changes in the market value of a single investment could
cause greater fluctuations in Share price than would occur in a diversified
fund. This may increase the Fund's volatility and cause the performance of a
relatively small number of issuers to have a greater impact on the Fund's
performance.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC
or any other government agency.

[1] Invesco PowerShares Capital Management LLC (the "Adviser") has agreed to waive fees and/or pay Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, brokerage commissions and other trading expenses, sub-licensing fees, offering costs, taxes and extraordinary expenses) from exceeding 0.60% of the Fund's average daily net assets per year (the "Expense Cap") until at least August 31, 2012, and neither the Adviser nor the Fund can discontinue the agreement prior to its expiration. The expenses borne by the Adviser are subject to recapture by the Adviser for up to three years from the date the fee or expense was borne by the Adviser; but no recapture payment will be made by the Fund if it would result in the Fund exceeding its Expense Cap.

Investment Strategy, Heading	rr_StrategyHeading	Principal Investment Strategies
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 90% of its total assets in the component securities that comprise the Underlying Index. The Underlying Index is comprised of common stocks of "small growth" U.S. companies (including real estate investment trusts ("REITs")) that Research Affiliates, LLC ("RAFI Affiliates" or the "Index Provider") classifies based on its Fundamental Index® methodology. Strictly in accordance with its existing guidelines and mandated procedures, the Index Provider identifies the common stocks for inclusion in the Underlying Index from a universe of the 2,500 largest U.S. companies. The use of the word "Fundamental" in the Fund's name reflects the fact that, in identifying the common stocks, the Index Provider uses fundamental measures of company size, rather than market capitalization (company share price multiplied by number of shares outstanding). The Index Provider uses the following fundamental measures to include common stocks in the Underlying Index: book value, income, sales and dividends. It then calculates a composite fundamental weight for each common stock by equally weighting the above four fundamental measures. The Index Provider then ranks each common stock by its fundamental weight and, based on this ranking, divides the common stocks into three size groups: "large," "mid" and "small." The common stocks it ranks in the top 70% of the eligible universe by fundamental weight comprise the "large" size group, the next 20% comprise the "mid" size group, and the final 10% comprise the "small" size group. The Index Provider further divides the "small" size group into "growth," "core" or "value" subsets based on the Fundamental Index® methodology style score, which uses a combination of fundamental growth rates and fundamental valuation ratios. The Underlying Index is composed only of those common stocks that the Index Provider classifies as both "small" and "growth." The Fund generally will invest at least 80% of its total assets in common stocks of "fundamentally small" companies. The Fund considers "fundamentally small" companies to be those companies that comprise the Underlying Index. The use of the word "Pure" in the Fund's name reflects that, in selecting securities for the Underlying Index, the Index Provider includes only those securities that it has classified as "growth." Although "growth" funds also could include some stocks that, based on their classification, would be considered "core" or "value," the Underlying Index contains only those stocks that the Index Provider classifies as pure "growth" stocks. The Fund generally will invest in all of the securities comprising its Underlying Index in proportion to their weightings in the Underlying Index. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.

The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. "Fundamentally Small" Company Risk. Investing in common stocks of "fundamentally small" companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies' common stocks may be more volatile and less liquid than those of more established companies. These common stocks may have returns that vary, sometimes significantly, from the overall stock market. Often "fundamentally small" companies and the industries in which they focus are still evolving and. As a result, they may be more sensitive to changing market conditions. Growth Risk. The market values of "growth" securities may be more volatile than other types of investments. The returns on "growth" securities may or may not move in tandem with the returns on other styles of investing or the overall stock market. Thus, the value of the Fund's investments will vary and at times may be lower or higher than that of other types of investments. REIT Risk. Although the Fund will not invest in real estate directly, the REITs in which the Fund invests are subject to risks inherent in the direct ownership of real estate. These risks include, but are not limited to, a possible lack of mortgage funds and associated interest rate risks, overbuilding, property vacancies, increases in property taxes and operating expenses, changes in zoning laws, losses due to environmental damages and changes in neighborhood values and appeal to purchasers. Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk.

[2] Invesco PowerShares Capital Management LLC (the "Adviser") has agreed to waive fees and/or pay Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, brokerage commissions and other trading expenses, offering costs, taxes and extraordinary expenses) from exceeding 0.39% of the Fund's average daily net assets per year (the "Expense Cap") until at least August 31, 2012, and neither the Adviser nor the Fund can discontinue the agreement prior to its expiration. The expenses borne by the Adviser are subject to recapture by the Adviser for up to three years from the date the fee or expense was borne by the Adviser, but no recapture payment will be made by the Fund if it would result in the Fund exceeding its Expense Cap.

Expense, Heading	rr_ExpenseHeading	Fund Fees and Expenses
Expense, Narrative	rr_ExpenseNarrativeTextBlock	This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund ("Shares"). Investors may pay brokerage commissions on their purchases and sales of Shares, which are not reflected in the table or the example below.

Portfolio Turnover	rr_PortfolioTurnoverTextBlock	The Fund pays transaction costs, such as commissions, when it purchases and sells securities (or "turns over" its portfolio). A higher portfolio turnover will cause the Fund to incur additional transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the example, may affect the Fund's performance. During the fiscal year ended April 30, 2011, the Fund's portfolio turnover rate was 68% of the average value of its portfolio.

Expense Example, Heading	rr_ExpenseExampleHeading	Example
Expense Example, Narrative	rr_ExpenseExampleNarrativeTextBlock	This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. This example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your Shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The cost under the one year example is equal to the Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the first year and the Total Annual Fund Operating Expenses thereafter. This example does not include the brokerage commissions that investors may pay to buy and sell Shares of the Fund.

Investment Strategy, Heading	rr_StrategyHeading	Principal Investment Strategies
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 90% of its total assets in the component securities that comprise the Underlying Index. The Underlying Index is comprised of common stocks of "small core" U.S. companies (including real estate investment trusts ("REITs")) that Research Affiliates, LLC ("RAFI Affiliates" or the "Index Provider") classifies based on its Fundamental Index® methodology. Strictly in accordance with its existing guidelines and mandated procedures, the Index Provider identifies the common stocks for inclusion in the Underlying Index from a universe of the 2,500 largest U.S. companies. The use of the word "Fundamental" in the Fund's name reflects the fact that, in identifying the common stocks, the Index Provider uses fundamental measures of company size, rather than market capitalization (company share price multiplied by number of shares outstanding). The Index Provider uses the following fundamental measures to include common stocks in the Underlying Index: book value, income, sales and dividends. It then calculates a composite fundamental weight for each common stock by equally weighting the above four fundamental measures. The Index Provider then ranks each common stock by its fundamental weight and, based on this ranking, divides the common stock into three size groups: "large," "mid" and "small." The common stocks it ranks in the top 70% of the eligible universe by fundamental weight comprise the "large" size group, the next 20% comprise the "mid" size group, and the final 10% comprise the "small" size group. The Index Provider further divides the "small" size group into "growth," "core" or "value" subsets based on the Fundamental Index® methodology style score, which uses a combination of fundamental growth rates and fundamental valuation ratios. The Underlying Index is composed only of those common stocks that the Index Provider classifies as both "small" and "core." The Fund generally will invest at least 80% of its total assets in common stocks of "fundamentally small" companies. The Fund considers "fundamentally small" companies to be those companies that comprise the Underlying Index. The use of the word "Pure" in the Fund's name reflects that, in selecting securities for the Underlying Index, the Index Provider includes only those securities that it has classified as "core." Although "core" funds also could include some stocks that, based on their classification, would be considered "growth" or "value," the Underlying Index contains only those stocks that the Index Provider classifies as pure "core" stocks. The Fund generally will invest in all of the securities comprising its Underlying Index in proportion to their weightings in the Underlying Index. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Investment Strategy, Portfolio Concentration	rr_StrategyPortfolioConcentration	The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. Core Risk. The returns on "core" securities may or may not move in tandem with the returns on other styles of investing or the overall stock market. Thus, the value of the Fund's investments will vary and at times may be lower or higher than that of other types of investments. "Fundamentally Small" Company Risk. Investing in common stocks of "fundamentally small" companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies' common stocks may be more volatile and less liquid than those of more established companies. These common stocks may have returns that vary, sometimes significantly, from the overall stock market. Often "fundamentally small" companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. REIT Risk. Although the Fund will not invest in real estate directly, the REITs in which the Fund invests are subject to risks inherent in the direct ownership of real estate. These risks include, but are not limited to, a possible lack of mortgage funds and associated interest rate risks, overbuilding, property vacancies, increases in property taxes and operating expenses, changes in zoning laws, losses due to environmental damages and changes in neighborhood values and appeal to purchasers. Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Index may be comprised of issuers in a single industry or sector of the economy. If the Fund is focused in an industry or sector, it may present more risks than if it were diversified broadly over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries or the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Index resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

In the event of negative performance displayed in the table below, the Fund's returns after taxes on distributions and sale of Fund Shares are calculated assuming that an investor has sufficient capital gains of the same character from other investments to offset any capital losses from the sale of Fund Shares so that the investor may deduct the losses in full. As a result, the Fund's returns after taxes on distributions and sale of Fund Shares may exceed the Fund's returns before taxes and/or returns after taxes on distributions.

Investment Strategy, Heading	rr_StrategyHeading	Principal Investment Strategies
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 90% of its total assets in the securities that comprise the International Dividend AchieversTM Index. The Underlying Index currently is composed of global depositary receipts ("GDRs") and American depositary receipts ("ADRs") that are listed on the London Stock Exchange ("LSE"), in addition to ADRs and non-U.S. common or ordinary stocks traded on the New York Stock Exchange ("NYSE"), the NASDAQ Stock Market LLC ("NASDAQ") or NYSE Amex of companies that have increased their aggregate annual regular dividend payments consistently over the course of the last five calendar or fiscal years. Strictly in accordance with its existing guidelines and mandated procedures, Mergent®, Inc. ("Mergent" or the "Index Provider") includes stock in the Underlying Index pursuant to a proprietary selection methodology. As of June 30, 2011, the Underlying Index was composed of approximately 64 securities selected principally on the basis of their consecutive years of dividend growth with a market capitalization range of between approximately $135 million and $216 billion. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.

Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. Dividend Paying Security Risk. Securities that pay high dividends as a group can fall out of favor with the market, causing such companies to underperform companies that do not pay high dividends. Also changes in the dividend policies of the companies in the Underlying Index and the capital resources available for such companies' dividend payments may affect the Fund. Financial Sector Risk. The market value of securities of issuers in the financial sector can be affected by factors such as adverse regulatory or economic occurrences affecting the financial sector, availability of credit, fluctuations in asset values, unstable interest rates, increased competition, continuing consolidations and development of new products and structures. Furthermore, increased government involvement in financial institutions, including measures such as taking ownership positions in such institutions, could result in a dilution in the value of the shares held by shareholders in such institutions. Foreign Securities Risk. The Fund's investments in foreign securities involve risks that are in addition to the risks associated with domestic securities. Foreign companies, in general, are not subject to the regulatory requirements of U.S. companies and, as such, there may be less publicly available information about these companies. Moreover, foreign companies are often subject to less stringent requirements regarding accounting, auditing, financial reporting and record-keeping than are U.S. companies, and therefore, not all material information regarding these companies will be available. Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Index may be composed of issuers in a single industry or sector of the economy. If the Fund is focused in an industry or sector, it may present more risks than if it were diversified broadly over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries or the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Index resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming. Small and Medium Capitalization Company Risk. Investing in securities of small and medium capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Often small and medium capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC or any other government agency.

[1] Invesco PowerShares Capital Management LLC (the "Adviser") has agreed to waive fees and/or pay Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, brokerage commissions and other trading expenses, sub-licensing fees, offering costs, taxes and extraordinary expenses) from exceeding 0.50% of the Fund's average daily net assets per year (the "Expense Cap") until at least August 31, 2012, and neither the Adviser nor the Fund can discontinue the agreement prior to its expiration. The expenses borne by the Adviser are subject to recapture by the Adviser for up to three years from the date the fee or expense was borne by the Adviser; but no recapture payment will be made by the Fund if it would result in the Fund exceeding its Expense Cap.

PowerShares S&P 500 High Quality Portfolio (Prospectus Summary) | PowerShares S&P 500 High Quality Portfolio

PowerShares S&P 500® High Quality Portfolio

Investment Objective

The PowerShares S&P 500® High Quality Portfolio (the "Fund") seeks investment
results that generally correspond (before fees and expenses) to the price and
yield of the S&P 500® High Quality Rankings Index* (the "Underlying Index").

* Standard & Poor's® and S&P® are registered trademarks of Standard & Poor's
Financial Services LLC ("Standard & Poor's") and have been licensed for use by
the Adviser. The Fund is not sponsored, endorsed, sold or promoted by Standard &
Poor's or its Affiliates, and Standard & Poor's and its Affiliates make no
representation, warranty or condition regarding the advisability of buying,
selling or holding shares of the Fund.

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors may pay brokerage commissions on their
purchases and sales of Shares, which are not reflected in the table or the
example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		PowerShares S&P 500 High Quality Portfolio
Management Fees		0.50%
Other Expenses		0.34%
Total Annual Fund Operating Expenses		0.84%
Fee Waivers and Expense Assumption	[1]	0.32%
Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption	[1]	0.52%

Example

This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. This example assumes that you invest
$10,000 in the Fund for the time periods indicated and then sell all of your
Shares at the end of those periods. The example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. The cost under the one year example is equal to the Total
Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the
first year and the Total Annual Fund Operating Expenses thereafter. This example
does not include the brokerage commissions that investors may pay to buy and sell
Shares of the Fund.

Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Expense Example (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
PowerShares S&P 500 High Quality Portfolio	53	236	435	1,008

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover rate was 64% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 90% of its total assets in securities
that comprise the Underlying Index. The Underlying Index is designed to provide
exposure to the constituents of the S&P 500® Index that S&P Quality Rankings
identifies as high quality stocks. Quality Rankings reflect the long-term growth
and stability of a company's earnings and dividends. Stocks with a Quality
Ranking of A- or above comprise the Underlying Index. Strictly in accordance
with its existing guidelines and mandated procedures, S&P Quality Rankings
assigns stocks Quality Rank Scores from 1 to 3, with a higher Quality Rank
leading to a higher Quality Rank Score. As of June 30, 2011, the Underlying
Index consisted of common stocks of approximately 125 companies with a market
capitalization range of between approximately $2 billion and $400 billion.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying Index
reflects a concentration in that industry or group of industries. The Fund will
not otherwise concentrate its investments in securities of issuers in any one
industry or group of industries.

Principal Risks of the Fund

The following summarizes the principal risks of the Fund.

Market Risk. Securities in the Underlying Index are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Index.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets, and disruption in the creation/redemption process of the
Fund. Any of these factors may lead to the Shares trading at a premium or
discount to the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a drop
in the stock market may depress the price of most or all of the common stocks and
other equity securities the Fund holds. In addition, common stock in the Fund's
portfolio may decline in price if the issuer fails to make anticipated dividend
payments because, among other reasons, the issuer of the security experiences a
decline in its financial condition. Common stock is subordinated to preferred
stocks, bonds and other debt instruments in a company's capital structure, in
terms of priority to corporate income, and therefore will be subject to greater
dividend risk than preferred stocks or debt instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Index may be
composed of issuers in a single industry or sector of the economy. If the Fund
is focused in an industry or sector, it may present more risks than if it were
broadly diversified over numerous industries and sectors of the economy. At
times, such industry or group of industries may be out of favor and underperform
other industries of the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Index for a number of reasons. For example, the Fund incurs operating
expenses not applicable to the Underlying Index, and incurs costs in buying and
selling securities, especially when rebalancing the Fund's securities holdings
to reflect changes in the composition of the Underlying Index. In addition, the
performance of the Fund and the Underlying Index may vary due to asset valuation
differences and differences between the Fund's portfolio and the Underlying
Index resulting from legal restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Index.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Index, even if that
security generally is underperforming.

Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater
portion of assets in securities of individual issuers than a diversified fund.
As a result, changes in the market value of a single investment could cause
greater fluctuations in share price than would occur in a diversified fund. This
may increase the Fund's volatility and cause the performance of a relatively
small number of issuers to have a greater impact on the Fund's performance.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC
or any other government agency.

Performance

The bar chart below shows how the Fund has performed. The table below the bar
chart shows the Fund's average annual total returns (before and after taxes).
The bar chart and table provide an indication of the risks of investing in the
Fund by showing how the Fund's total return has varied from year to year and by
showing how the Fund's average annual total returns compared with a broad
measure of market performance. The Fund's performance reflects fee waivers, if
any, absent which, performance would have been lower. Although the information
shown in the bar chart and the table gives you some idea of the risks involved
in investing in the Fund, the Fund's past performance (before and after taxes)
is not necessarily indicative of how the Fund will perform in the future. Updated
performance information is available online at www.InvescoPowerShares.com.

The bar chart below shows how the Fund has performed.

Annual Total Returns-Calendar Years

The Fund's year-to-date total return for the six months ended June 30, 2011 was
8.24%.

After-tax returns in the table below are calculated using the historical highest
individual federal marginal income tax rates and do not reflect the impact of
state and local taxes. Actual after-tax returns depend on an investor's tax
situation and may differ from those shown, and after-tax returns shown are not
relevant to investors who hold Shares through tax-deferred arrangements, such as
401(k) plans or individual retirement accounts. In the event of negative
performance displayed in the table below, the Fund's returns after taxes on
distributions and sale of Fund Shares are calculated assuming that an investor
has sufficient capital gains of the same character from other investments to
offset any capital losses from the sale of Fund Shares so that the investor may
deduct the losses in full. As a result, the Fund's returns after taxes on
distributions and sale of Fund Shares may exceed the Fund's returns before taxes
and/or returns after taxes on distributions.

Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund normally will invest at least 90% of its total assets in common stocks and American depositary receipts ("ADRs") that comprise the Palisades Water Index (the "Underlying Index"). The components of the Underlying Index are selected based on the objective of providing a representative indicator of the water business through the inclusion of companies whose water or water-related activities stand to benefit from meeting the issues associated with the provision of water and the management of water resources. The Underlying Index was created by, and is a trademark of, Palisades Water Index Associates, LLC (the "Index Provider"). As of June 30, 2011, the Underlying Index was composed of stocks of 32 companies that are publicly traded in the United States. Strictly in accordance with its existing guidelines and rules, the Index Provider will include small and medium capitalization stocks as a portion of the Underlying Index. As of June 30, 2011, the Underlying Index included companies with a market capitalization range of between approximately $160 million and $30 billion. The Fund generally invests in all of the securities comprising its Underlying Index in proportion to their weightings in the Underlying Index.

By focusing in an industry or sector, the Fund faces more risks than if it were diversified broadly over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries or the market as a whole.
Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. Risk of Concentrating in the Water Industry. Adverse developments in the water industry may significantly affect the value of the Shares of the Fund. Companies involved in the water industry are subject to environmental considerations, taxes, government regulation, price and supply fluctuations, competition and water conservation. Foreign Securities Risk. Since the Underlying Index may include ADRs, the Fund's investments involve risks of investing in foreign securities that are in addition to the risks associated with domestic securities. Foreign companies, in general, are not subject to the regulatory requirements of U.S. companies and, as such, there may be less publicly available information about these companies. Moreover, foreign companies are often subject to less stringent requirements regarding accounting, auditing, financial reporting and record-keeping than are U.S. companies, and therefore, not all material information regarding these companies will be available. Sampling Risk. The Fund's use of a representative sampling approach will result in its holding a smaller number of securities than are in the Underlying Index. As a result, an adverse development respecting an issuer of securities held by the Fund could result in a greater decline in NAV than would be the case if the Fund held all of the securities in the Underlying Index. To the extent the assets in the Fund are smaller, these risks will be greater. Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Index is comprised of issuers in a single industry or sector of the economy.

At times, such industry or group of industries may be out of favor and underperform other industries or the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Index. The Fund does not purchase all of the securities in the Underlying Index. Instead, the Adviser utilizes a "sampling" methodology in seeking to achieve the Fund's investment objective. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Index resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming. Small and Medium Capitalization Company Risk. Investing in securities of small and medium capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Often small and medium capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund's volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund's performance. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC or any other government agency.

[1] Invesco PowerShares Capital Management LLC (the "Adviser") has agreed to waive fees and/or pay Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, brokerage commissions and other trading expenses, sub-licensing fees, offering costs, taxes and extraordinary expenses) from exceeding 0.60% of the Fund's average daily net assets per year (the "Expense Cap") until at least August 31, 2012, and neither the Adviser nor the Fund can discontinue the agreement prior to its expiration. The expenses borne by the Adviser are subject to recapture by the Adviser for up to three years from the date the fee or expense was borne by the Adviser, but no recapture payment will be made by the Fund if it would result in the Fund exceeding its Expense Cap.

Portfolio Turnover	rr_PortfolioTurnoverTextBlock	The Fund pays transaction costs, such as commissions, when it purchases and sells securities (or "turns over" its portfolio). A higher portfolio turnover will cause the Fund to incur additional transaction costs and may result in higher taxes when Fund Shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the example, may affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 45% of the average value of its portfolio.

Expense Example, Heading	rr_ExpenseExampleHeading	Example
Expense Example, Narrative	rr_ExpenseExampleNarrativeTextBlock	This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. This example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your Shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The cost under the one year example is equal to the Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the first year and the Total Annual Fund Operating Expenses thereafter. This example does not include the brokerage commissions that investors may pay to buy and sell Shares of the Fund.

Investment Strategy, Heading	rr_StrategyHeading	Principal Investment Strategies
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 80% of its total assets in common stocks of large capitalization companies. NYSE Arca, Inc. ("NYSE Arca" or the "Intellidex Provider") considers a company to be a large capitalization company if it falls within the Underlying Intellidex model, as described below. The Fund generally will invest at least 90% of its total assets in common stocks that comprise the Underlying Intellidex. As of June 30, 2011, the Underlying Intellidex was composed of 50 large capitalization U.S. growth stocks that, strictly in accordance with its existing guidelines and mandated procedures, NYSE Arca included principally on the basis of their capital appreciation potential that NYSE Arca identifies pursuant to a proprietary Intellidex methodology. As of June 30, 2011, the Underlying Intellidex included common stocks of companies with a market capitalization range of between approximately $10 billion and $311 billion. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Intellidex reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Investment Strategy, Portfolio Concentration	rr_StrategyPortfolioConcentration	The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Intellidex reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. Growth Investing Style Risk. The market values of "growth" securities may be more volatile than other types of investments. The returns on "growth" securities may or may not move in tandem with the returns on other styles of investing or the overall stock market. Thus, the value of the Fund's investments will vary and at times may be lower or higher than that of other types of investments. Market Risk. Securities in the Underlying Intellidex are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Intellidex. Market Trading Risk. The Fund faces market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Intellidex may be composed of issuers in a single industry or sector of the economy. If the Fund is focused in an industry or sector, it may present more risks than if it were diversified broadly over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries or the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Intellidex for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Intellidex, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Intellidex. In addition, the performance of the Fund and the Underlying Intellidex may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Intellidex resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Intellidex. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Intellidex, even if that security generally is underperforming. Large Capitalization Company Risk. Companies with large market capitalizations may go in and out of favor based on market and economic conditions. Although larger companies tend to be less volatile than companies with smaller market capitalizations, returns on investments in securities of large capitalization U.S. companies could trail the returns on investments in stocks of smaller companies. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC or any other government agency.

PowerShares Dynamic Software Portfolio (Prospectus Summary) | PowerShares Dynamic Software Portfolio

PowerShares Dynamic Software Portfolio

Investment Objective

The PowerShares Dynamic Software Portfolio (the "Fund") seeks investment results
that generally correspond (before fees and expenses) to the price and yield of
the Dynamic Software IntellidexSM Index (the "Underlying Intellidex").

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors may pay brokerage commissions on their
purchases and sales of Shares, which are not reflected in the table or the
example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		PowerShares Dynamic Software Portfolio
Management Fees		0.50%
Other Expenses		0.27%
Total Annual Fund Operating Expenses		0.77%
Fee Waivers and Expense Assumption	[1]	0.14%
Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption	[1]	0.63%

Example

This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. This example assumes that you invest
$10,000 in the Fund for the time periods indicated and then sell all of your
Shares at the end of those periods. The example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. The cost under the one year example is equal to the Total
Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the
first year and the Total Annual Fund Operating Expenses thereafter. This example
does not include the brokerage commissions that investors may pay to buy and
sell Shares of the Fund.

Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Expense Example (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
PowerShares Dynamic Software Portfolio	64	232	414	941

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover rate was 46% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 80% of its total assets in common stocks
of software companies. The Fund generally will invest at least 90% of its total
assets in common stocks that comprise the Underlying Intellidex. As of June 30,
2011, the Underlying Intellidex was composed of stocks of 30 U.S. software
companies. These companies are engaged principally in the research, design,
production or distribution of products or processes that relate to software
applications and systems and information-based services. These companies may
include, for example, companies that design products such as systems-level
software (to run the basic functions of a computer) or applications software
(for one type of work) for general use or use by certain industries or groups;
companies that provide communications software; and companies that provide
time-sharing services, internet software and home entertainment software.
Strictly in accordance with its existing guidelines and mandated procedures, the
Intellidex Provider includes stocks principally on the basis of their capital
appreciation potential that it identifies pursuant to a proprietary Intellidex
methodology. As of June 30, 2011, the Underlying Intellidex included common
stocks of companies with a market capitalization range of between approximately
$474 million and $173 billion.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying
Intellidex reflects a concentration in that industry or group of industries. The
Fund will not otherwise concentrate its investments in securities of issuers in
any one industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Software Industry Concentration Risk. Technological developments, fixed-rate
pricing and the ability to attract and retain skilled employees, can
significantly affect the software industry. The success of companies in the
industry is also subject to the continued demand for internet services.

Market Risk. Securities in the Underlying Intellidex are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Intellidex.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets, and disruption in the creation/redemption process of the
Fund. Any of these factors may lead to the Shares trading at a premium or
discount to the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or debt
instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Intellidex is
comprised of issuers in a single industry or sector of the economy. By focusing
in an industry or sector, the Fund faces more risks than if it were diversified
broadly over numerous industries and sectors of the economy. At times, such
industry or group of industries may be out of favor and underperform other
industries or the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Intellidex for a number of reasons. For example, the Fund incurs
operating expenses not applicable to the Underlying Intellidex, and incurs costs
in buying and selling securities, especially when rebalancing the Fund's
securities holdings to reflect changes in the composition of the Underlying
Intellidex. In addition, the performance of the Fund and the Underlying
Intellidex may vary due to asset valuation differences and differences between
the Fund's portfolio and the Underlying Intellidex resulting from legal
restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Intellidex.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Intellidex, even if that
security generally is underperforming.

Small and Medium Capitalization Company Risk. Investing in securities of small
and medium capitalization companies involves greater risk than customarily is
associated with investing in larger, more established companies. These
companies' securities may be more volatile and less liquid than those of more
established companies. These securities may have returns that vary, sometimes
significantly, from the overall securities market. Often small and medium
capitalization companies and the industries in which they focus are still
evolving and, as a result, they may be more sensitive to changing market
conditions.

Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater
portion of its assets in securities of individual issuers than a diversified
fund. As a result, changes in the market value of a single investment could
cause greater fluctuations in Share price than would occur in a diversified
fund. This may increase the Fund's volatility and cause the performance of a
relatively small number of issuers to have a greater impact on the Fund's
performance.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC
or any other government agency.

Performance

The bar chart below shows how the Fund has performed. The table below the bar
chart shows the Fund's average annual total returns (before and after taxes).
The bar chart and table provide an indication of the risks of investing in the
Fund by showing how the Fund's total return has varied from year to year and by
showing how the Fund's average annual total returns compared with a broad
measure of market performance. The Fund's performance reflects fee waivers, if
any, absent which, performance would have been lower. Although the information
shown in the bar chart and the table gives you some idea of the risks involved
in investing in the Fund, the Fund's past performance (before and after taxes)
is not necessarily indicative of how the Fund will perform in the future.

PowerShares Fundamental Pure Mid Core Portfolio (Prospectus Summary) | PowerShares Fundamental Pure Mid Core Portfolio

PowerShares Fundamental Pure Mid Core Portfolio

Investment Objective

The PowerShares Fundamental Pure Mid Core Portfolio (the "Fund") seeks
investment results that generally correspond (before fees and expenses) to the
price and yield of the RAFI® Fundamental Mid Core Index (the "Underlying
Index").

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors may pay brokerage commissions on their
purchases and sales of Shares, which are not reflected in the table or the
example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		PowerShares Fundamental Pure Mid Core Portfolio
Management Fees		0.29%
Other Expenses		0.91%
Total Annual Fund Operating Expenses		1.20%
Fee Waivers and Expense Assumption	[1]	0.55%
Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption	[1]	0.65%

Example

This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. This example assumes that you invest
$10,000 in the Fund for the time periods indicated and then sell all of your
Shares at the end of those periods. The example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. The cost under the one year example is equal to the Total
Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the
first year and the Total Annual Fund Operating Expenses thereafter. This example
does not include the brokerage commissions that investors may pay to buy and
sell Shares of the Fund.

Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Expense Example (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
PowerShares Fundamental Pure Mid Core Portfolio	66	326	607	1,406

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Shares are held in a taxable account. These costs, which are
not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the fiscal year ended April 30, 2011, the
Fund's portfolio turnover rate was 47% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 90% of its total assets in the component
securities that comprise the Underlying Index. The Underlying Index is comprised
of common stocks of "mid core" U.S. companies (including real estate investment
trusts ("REITs")) that Research Affiliates, LLC ("RAFI Affiliates" or the "Index
Provider") classifies based on the its Fundamental Index® methodology. Strictly
in accordance with its existing guidelines and mandated procedures, the Index
Provider identifies the common stocks for inclusion in the Underlying Index from
a universe of the 2,500 largest U.S. companies. The use of the word
"Fundamental" in the Fund's name reflects the fact that, in identifying the
common stocks, the Index Provider uses fundamental measures of company size,
rather than market capitalization (company share price multiplied by number of
shares outstanding). The Index Provider uses the following fundamental measures
to include common stocks in the Underlying Index: book value, income, sales and
dividends. It then calculates a composite fundamental weight for each common
stock by equally weighting the above four fundamental measures. The Index
Provider then ranks each common stock by its fundamental weight and, based on
this ranking, divides the common stocks into three size groups: "large," "mid"
and "small." The common stocks it ranks in the top 70% of the eligible universe
by fundamental weight comprise the "large" size group, the next 20% comprise the
"mid" size group, and the final 10% comprise the "small" size group. The Index
Provider further divides the "mid" size group into "growth," "core" or "value"
subsets based on the Fundamental Index® methodology style score, which uses a
combination of fundamental growth rates and fundamental valuation ratios. The
Underlying Index is composed only of those common stocks that the Index Provider
classifies as both "mid" and "core." The Fund generally will invest at least 80%
of its total assets in common stocks of "fundamentally mid" companies. The Fund
considers "fundamentally mid" companies to be those companies that comprise the
Underlying Index.

The use of the word "Pure" in the Fund's name reflects that, in selecting
securities for the Underlying Index, the Index Provider includes only those
securities that it has classified as "core." Although "core" funds also could
include some stocks that, based on their classification, would be considered
"growth" or "value," the Underlying Index contains only those stocks that the
Index Provider classifies as pure "core" stocks. The Fund generally will invest
in all of the securities comprising its Underlying Index in proportion to their
weightings in the Underlying Index.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying Index
reflects a concentration in that industry or group of industries. The Fund will
not otherwise concentrate its investments in securities of issuers in any one
industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Core Risk. The returns on "core" securities may or may not move in tandem with
the returns on other styles of investing or the overall stock market. Thus, the
value of the Fund's investments will vary and at times may be lower or higher
than that of other types of investments.

"Fundamentally Mid" Company Risk. Investing in common stocks of "fundamentally
mid" companies involves greater risk than customarily is associated with
investing in larger, more established companies. These companies' common stocks
may be more volatile and less liquid than those of more established companies.
These common stocks may have returns that vary, sometimes significantly, from
the overall stock market. Often "fundamentally mid" companies and the industries
in which they focus are still evolving and, as a result, they may be more
sensitive to changing market conditions.

REIT Risk. Although the Fund will not invest in real estate directly, the REITs
in which the Fund invests are subject to risks inherent in the direct ownership
of real estate. These risks include, but are not limited to, a possible lack of
mortgage funds and associated interest rate risks, overbuilding, property
vacancies, increases in property taxes and operating expenses, changes in zoning
laws, losses due to environmental damages and changes in neighborhood values and
appeal to purchasers.

Market Risk. Securities in the Underlying Index are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Index.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets, and disruption in the creation/redemption process of the
Fund. Any of these factors may lead to the Shares trading at a premium or
discount to the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or debt
instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Index may be
comprised of issuers in a single industry or sector of the economy. If the Fund
is focused in an industry or sector, it may present more risks than if it were
diversified broadly over numerous industries and sectors of the economy. At
times, such industry or group of industries may be out of favor and underperform
other industries or the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Index for a number of reasons. For example, the Fund incurs operating
expenses not applicable to the Underlying Index, and incurs costs in buying and
selling securities, especially when rebalancing the Fund's securities holdings
to reflect changes in the composition of the Underlying Index. In addition, the
performance of the Fund and the Underlying Index may vary due to asset valuation
differences and differences between the Fund's portfolio and the Underlying
Index resulting from legal restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Index.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Index, even if that
security generally is underperforming.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the
Federal Deposit insurance Corporation or any other government agency.

Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 80% of its total assets in common stocks of the 500 companies included in the S&P 500® Index (the "S&P 500 Index" or the "Reference Index") and will write (sell) call options thereon. The Underlying Index measures total returns of a theoretical portfolio including the S&P 500 Index stocks on which S&P 500 Index call options are written (sold) systemically against the portfolio through a "buy-write" strategy. A "buy-write," also called a covered call, generally is considered an investment strategy in which an investor buys a stock or basket of stocks, and sells call options that correspond to the stock or basket of stocks. In return for a premium, the Fund gives the right to the purchaser of the option written by the Fund to receive a cash payment equal to the difference between the value of the S&P 500 Index and the exercise price, if the value on the expiration date is above the exercise price. In addition, covered call options partially hedge against a decline in the price of the securities on which they are written to the extent of the premium the Fund receives. The Fund will write options that are traded on national securities exchanges. Strictly in accordance with its existing guidelines and mandated procedures, the Chicago Board Options Exchange (the "CBOE" or the "Index Provider") calculates the Underlying Index. As of June 30, 2011, the S&P 500 Index included common stocks of 500 companies with a market capitalization range of between approximately $1.4 billion and $400.9 billion. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.

Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. Writing Covered Call Option Risk. By writing covered call options in return for the receipt of premiums, the Fund will give up the opportunity to benefit from potential increases in the value of the S&P 500 Index above the exercise prices of the Written Options, but will continue to bear the risk of declines in the value of the S&P 500 Index. The premiums received from the options may not be sufficient to offset any losses sustained from the volatility of the underlying stocks over time. In addition, the Fund's ability to sell the underlying securities will be limited while the option is in effect unless the Fund extinguishes the option position through the purchase of an offsetting identical option prior to the expiration of the written option. Exchanges may suspend the trading of options in volatile markets. If trading is suspended, the Fund may be unable to write options at times that may be desirable or advantageous to the Fund to do so. U.S. Federal Income Tax Risk. Due to its investment strategy and U.S. federal income tax elections, the Fund expects to account for gains or losses on its investments on a daily mark-to-market basis for federal income tax purposes. Generally, the mark-to-market gains and losses from the stock positions will be compared with the mark-to-market gains or losses from the call options on a daily basis. To the extent that there is more gain or loss from the stock positions, the Fund will have short term capital gain, which generally is taxed like ordinary income, or short term capital loss. To the extent there is more gain or loss from the call options, such gain will be 60% long term capital gain or loss and 40% short term capital gain. These rules also impose limits on the total percentage of gain for the tax year that can be characterized as long term capital gain and the percentage of loss for the tax year that can be characterized as short term capital loss. As a result of its investment strategy, the Fund will not be able to designate a portion of its dividends as being eligible for lower rates of tax in the hands of non-corporate shareholders (dividends that are commonly referred to as "qualified dividend income") or as being eligible for the dividends received deduction when received by certain corporate shareholders. For these reasons, a significant portion of income received from the Fund may be subject to tax at greater rates than would apply if the Fund were engaged in a different investment strategy. You should consult your tax advisors as to the tax consequences of acquiring, owning and disposing of shares in the Fund. Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Index may be composed of issuers in a single industry or sector of the economy. If the Fund is focused in an industry or sector, it may present more risks than if it were broadly diversified over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries of the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Index resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming. Large Capitalization Company Risk. Returns on investments in securities of large capitalization U.S. companies could trail the returns on investments in stocks of smaller companies. Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund's volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund's performance. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC or any other government agency.

PowerShares High Yield Equity Dividend Achievers Portfolio (Prospectus Summary) | PowerShares High Yield Equity Dividend Achievers Portfolio

PowerShares High Yield Equity Dividend AchieversTM Portfolio

Investment Objective

The PowerShares High Yield Equity Dividend AchieversTM Portfolio (the "Fund")
seeks investment results that generally correspond (before fees and expenses) to
the price and yield of the Mergent Dividend AchieversTM 50 Index (the
"Underlying Index").

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors may pay brokerage commissions on their
purchases and sales of Shares, which are not reflected in the table or the
example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		PowerShares High Yield Equity Dividend Achievers Portfolio
Management Fees		0.40%
Other Expenses		0.22%
Total Annual Fund Operating Expenses		0.62%
Fee Waivers and Expense Assumption	[1]	0.02%
Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption	[1]	0.60%

Example

This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. This example assumes that you invest
$10,000 in the Fund for the time periods indicated and then sell all of your
Shares at the end of those periods. The example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. The cost under the one year example is equal to the Total
Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the
first year and the Total Annual Fund Operating Expenses thereafter. This example
does not include the brokerage commissions that investors may pay to buy and
sell Shares of the Fund.

Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Expense Example (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
PowerShares High Yield Equity Dividend Achievers Portfolio	61	197	344	772

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover rate was 44% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 80% of its total assets in common stocks
of companies that have a consistent record of dividend increases. The Fund
generally will invest at least 90% of its total assets in dividend-paying common
stocks that comprise the Underlying Index. Strictly in accordance with its
existing guidelines and mandated procedures, Mergent®, Inc. ("Mergent" or the
"Index Provider") includes stock in the Underlying Index, principally on the
basis of dividend yield and consistent growth in dividends. As of June 30, 2011,
the Underlying Index was composed of approximately 50 companies with a market
capitalization range of between approximately $289 million and $186 billion. The
Underlying Index contains only stocks and no debt or fixed income securities. To
qualify for the universe of "Dividend Achievers," an issuer must have increased
its annual regular cash dividend, on a pre-tax basis, for each of the last 10
fiscal years.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying Index
reflects a concentration in that industry or group of industries. The Fund will
not otherwise concentrate its investments in securities of issuers in any one
industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Dividend Paying Security Risk. Securities that pay high dividends as a group can
fall out of favor with the market, causing such companies to underperform
companies that do not pay high dividends. Also changes in the dividend policies
of the companies in the Underlying Index and the capital resources available for
such companies' dividend payments may affect the Fund.

High Yield Securities Risk. High yield securities typically involve greater risk
and are less liquid than higher grade issues. Changes in general economic
conditions, changes in the financial condition of the issuers and changes in
interest rates may adversely impact the ability of issuers of high yield
securities to make timely payments of interest and principal.

Market Risk. Securities in the Underlying Index are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Index.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets, and disruption in the creation/redemption process of the
Fund. Any of these factors may lead to the Shares trading at a premium or
discount to the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the fund Holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or debt
instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Index may be
composed of issuers in a single industry or sector of the economy. If the Fund
is focused in an industry or sector, it may present more risks than if it were
diversified broadly over numerous industries and sectors of the economy. At
times, such industry or group of industries may be out of favor and underperform
other industries or the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Index for a number of reasons. For example, the Fund incurs operating
expenses not applicable to the Underlying Index, and incurs costs in buying and
selling securities, especially when rebalancing the Fund's securities holdings
to reflect changes in the composition of the Underlying Index. In addition, the
performance of the Fund and the Underlying Index may vary due to asset valuation
differences and differences between the Fund's portfolio and the Underlying
Index resulting from legal restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Index.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Index, even if that
security generally is underperforming.

Small and Medium Capitalization Company Risk. Investing in securities of small
and medium capitalization companies involves greater risk than customarily is
associated with investing in larger, more established companies. These
companies' securities may be more volatile and less liquid than those of more
established companies. These securities may have returns that vary, sometimes
significantly, from the overall securities market. Often small and medium
capitalization companies and the industries in which they focus are still
evolving and, as a result, they may be more sensitive to changing market
conditions.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC
or any other government agency.

Performance

The bar chart below shows how the Fund has performed. The table below the bar
chart shows the Fund's average annual total returns (before and after taxes).
The bar chart and table provide an indication of the risks of investing in the
Fund by showing how the Fund's total return has varied from year to year and by
showing how the Fund's average annual total returns compared with a broad
measure of market performance. The Fund's performance reflects fee waivers, if
any, absent which, performance would have been lower. Although the information
shown in the bar chart and the table gives you some idea of the risks involved
in investing in the Fund, the Fund's past performance (before and after taxes)
is not necessarily indicative of how the Fund will perform in the future.

Annual Total Returns-Calendar Years

The Fund's year-to-date total return for the six months ended June 30, 2011 was
1.69%.

        Best Quarter                    Worst Quarter
26.81% (3rd Quarter 2008)       (30.52)% (1st Quarter 2009)

After-tax returns in the table below are calculated using the historical highest
individual federal marginal income tax rates and do not reflect the impact of
state and local taxes. Actual after-tax returns depend on an investor's tax
situation and may differ from those shown, and after-tax returns shown are not
relevant to investors who hold Shares through tax-deferred arrangements, such as
401(k) plans or individual retirement accounts. In the event of negative
performance displayed in the table below, the Fund's returns after taxes on
distributions and sale of Fund Shares are calculated assuming that an investor
has sufficient capital gains of the same character from other investments to
offset any capital losses from the sale of Fund Shares so that the investor may
deduct the losses in full. As a result, the Fund's returns after taxes on
distributions and sale of Fund Shares may exceed the Fund's returns before taxes
and/or returns after taxes on distributions.

[1] Invesco PowerShares Capital Management LLC (the "Adviser") has agreed to waive fees and/or pay Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, brokerage commissions and other trading expenses, sub-licensing fees, offering costs, taxes, and extraordinary expenses) from exceeding 0.50% of the Fund's average daily net assets per year (the "Expense Cap") until at least August 31, 2012, and neither the Adviser nor the Fund can discontinue the agreement prior to its expiration. The expenses borne by the Adviser are subject to recapture by the Adviser for up to three years from the date the fee or expense was borne by the Adviser; but no recapture payment will be made by the Fund if it would result in the Fund exceeding its Expense Cap.

PowerShares Dynamic Industrials Sector Portfolio (Prospectus Summary) | PowerShares Dynamic Industrials Sector Portfolio

PowerShares Dynamic Industrials Sector Portfolio

Investment Objective

The PowerShares Dynamic Industrials Sector Portfolio (the "Fund") seeks
investment results that generally correspond (before fees and expenses) to the
price and yield of the Dynamic Industrials Sector IntellidexSM Index (the
"Underlying Intellidex").

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors may pay brokerage commissions on their
purchases and sales of Shares, which are not reflected in the table or the
example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		PowerShares Dynamic Industrials Sector Portfolio
Management Fees		0.50%
Other Expenses		0.38%
Total Annual Fund Operating Expenses		0.88%
Fee Waivers and Expense Assumption	[1]	0.23%
Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption	[1]	0.65%

Example

This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. This example assumes that you invest
$10,000 in the Fund for the time periods indicated and then sell all of your
Shares at the end of those periods. The example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. The cost under the one year example is equal to the Total
Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the
first year and the Total Annual Fund Operating Expenses thereafter. This example
does not include the brokerage commissions that investors may pay to buy and sell
Shares of the Fund.

Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Expense Example (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
PowerShares Dynamic Industrials Sector Portfolio	66	258	465	1,063

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover was 48% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 80% of its total assets in common stocks
of industrial companies. The Fund generally will invest at least 90% of its
total assets in common stocks that comprise the Underlying Intellidex. As of
June 30, 2011, the Underlying Intellidex was comprised of stocks of 60 U.S.
industrial companies. These companies are principally engaged in the business of
providing industrial products and services, including engineering, heavy
machinery, construction, electrical equipment, aerospace and defense and general
manufacturing. Strictly in accordance with its existing guidelines and mandated
procedures, NYSE Arca, Inc. ("NYSE Arca" or the "Intellidex Provider") includes
stocks principally on the basis of their capital appreciation potential that it
identifies pursuant to a proprietary Intellidex methodology. As of June 30,
2011, the Underlying Intellidex included common stocks of companies with a
market capitalization range of between $344 million and $69 billion.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying
Intellidex reflects a concentration in that industry or group of industries. The
Fund will not otherwise concentrate its investments in securities of issuers in
any one industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Industrials Sector Risk. Changes in government regulation, world events and
economic conditions may adversely affect companies in the industrials sector. In
addition, these companies are at risk for environmental damage claims. Also,
commodity price volatility, changes in exchange rates, imposition of import
controls, increased competition, depletion of resources, technological
developments and labor relations could adversely affect the companies in this
sector.

Market Risk. Securities in the Underlying Intellidex are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Intellidex.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets and disruption in the creation/redemption process of the Fund.
Any of these factors may lead to the Shares trading at a premium or discount to
the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or debt
instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Intellidex is
comprised of issuers in a single industry or sector of the economy. By focusing
in an industry or sector, the Fund faces more risks than if it were diversified
broadly over numerous industries and sectors of the economy. At times, such
industry or group of industries may be out of favor and underperform other
industries or the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Intellidex for a number of reasons. For example, the Fund incurs
operating expenses not applicable to the Underlying Intellidex, and incurs costs
in buying and selling securities, especially when rebalancing the Fund's
securities holdings to reflect changes in the composition of the Underlying
Intellidex. In addition, the performance of the Fund and the Underlying
Intellidex may vary due to asset valuation differences and differences between
the Fund's portfolio and the Underlying Intellidex resulting from legal
restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Intellidex.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Intellidex, even if that
security generally is underperforming.

Small and Medium Capitalization Company Risk. Investing in securities of small
and medium capitalization companies involves greater risk than customarily is
associated with investing in larger, more established companies. These
companies' securities may be more volatile and less liquid than those of more
established companies. These securities may have returns that vary, sometimes
significantly, from the overall securities market. Often small and medium
capitalization companies and the industries in which they focus are still
evolving and, as a result, they may be more sensitive to changing market
conditions.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC
or any other government agency.

Performance

The bar chart below shows how the Fund has performed. The table below the bar
chart shows the Fund's average annual total returns (before and after taxes).
The bar chart and table provide an indication of the risks of investing in the
Fund by showing how the Fund's total return has varied from year to year and by
showing how the Fund's average annual total returns compared with a broad
measure of market performance. The Fund's performance reflects fee waivers, if
any, absent which, performance would have been lower. Although the information
shown in the bar chart and the table gives you some idea of the risks involved
in investing in the Fund, the Fund's past performance (before and after taxes)
is not necessarily indicative of how the Fund will perform in the future.
Updated performance information is available online at
www.InvescoPowerShares.com.

[1] Invesco PowerShares Capital Management LLC (the "Adviser") has agreed to waive fees and/or pay Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, brokerage commissions and other trading expenses, sub-licensing fees, offering costs, taxes and extraordinary expenses) from exceeding 0.60% of the Fund's average daily net assets per year (the "Expense Cap") until at least August 31, 2012, and neither the Adviser nor the Fund can discontinue the agreement prior to its expiration. The expenses borne by the Adviser are subject to recapture by the Adviser for up to three years from the date the fee or expense was borne by the Adviser, but no recapture payment will be made by the Fund if it would result in the Fund exceeding its Expense Cap.

Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. Healthcare Sector Risk. Factors such as extensive government regulation, restrictions on government reimbursement for medical expenses, rising costs of medical products and services, pricing pressure, an increased emphasis on outpatient services, limited number of products, industry innovation, costs associated with obtaining and protecting patents, product liability and other claims, changes in technologies and other market developments can affect companies in the healthcare sector.

PowerShares Dynamic Energy Sector Portfolio (Prospectus Summary) | PowerShares Dynamic Energy Sector Portfolio

PowerShares Dynamic Energy Sector Portfolio

Investment Objective

The PowerShares Dynamic Energy Sector Portfolio (the "Fund") seeks investment
results that generally correspond (before fees and expenses) to the price and
yield of the Dynamic Energy Sector IntellidexSM Index (the "Underlying
Intellidex").

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors may pay brokerage commissions on their
purchases and sales of Shares, which are not reflected in the table or the
example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		PowerShares Dynamic Energy Sector Portfolio
Management Fees		0.50%
Other Expenses		0.24%
Total Annual Fund Operating Expenses		0.74%
Fee Waivers and Expense Assumption	[1]	0.09%
Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption	[1]	0.65%

Example

This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. This example assumes that you invest
$10,000 in the Fund for the time periods indicated and then sell all of your
Shares at the end of those periods. The example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. The cost under the one year example is equal to the Total
Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the
first year and the Total Annual Fund Operating Expenses thereafter. This example
does not include the brokerage commissions that investors may pay to buy and
sell Shares of the Fund.

Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Expense Example (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
PowerShares Dynamic Energy Sector Portfolio	66	228	403	910

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover was 35% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 80% of its total assets in common stocks
of energy companies. The Fund generally will invest at least 90% of its total
assets in common stocks that comprise the Underlying Intellidex. As of June 30,
2011, the Underlying Intellidex was comprised of stocks of 60 U.S. energy
companies. These companies are principally engaged in the business of producing,
distributing or servicing energy-related products, including oil and gas
exploration and production, refining, oil services, pipeline, and solar, wind
and other non-oil based energy. Strictly in accordance with its existing
guidelines and mandated procedures, NYSE Arca, Inc. ("NYSE Arca" or the
"Intellidex Provider") includes stocks principally on the basis of their capital
appreciation potential that it identifies pursuant to a proprietary Intellidex
methodology. As of June 30, 2011, the Underlying Intellidex included common
stocks of companies with a market capitalization range of between $343 million
and $400 billion.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying
Intellidex reflects a concentration in that industry or group of industries. The
Fund will not otherwise concentrate its investments in securities of issuers in
any one industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Energy Sector Risk. Changes in worldwide energy prices, exploration and
production spending may adversely affect companies in the energy sector. Changes
in government regulation, world events and economic conditions also affect these
companies. In addition, these companies are at risk of civil liability from
accidents resulting in injury, loss of life or property, pollution or other
environmental damage claims and risk of loss from terrorism and natural
disasters. Commodity price volatility, changes in exchange rates, imposition of
import controls, increased competition, depletion of resources, development of
alternative energy sources, technological developments and labor relations also
could affect companies in this sector.

Oil and Gas Services Industry Risk. The profitability of companies in the oil
and gas services industry may be affected adversely by world events in the
regions that the companies operate (e.g., expropriation, nationalization,
confiscation of assets and property or the imposition of restrictions on foreign
investments and repatriation of capital, military coups, social unrest, violence
or labor unrest). Companies in the oil and gas services industry may have significant
capital investments in, or engage in transactions involving, emerging market
countries, which may heighten these risks.

Market Risk. Securities in the Underlying Intellidex are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Intellidex.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets and disruption in the creation/redemption process of the Fund.
Any of these factors may lead to the Shares trading at a premium or discount to
the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or debt
instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Intellidex is
comprised of issuers in a single industry or sector of the economy. By focusing
in an industry or sector, the Fund faces more risks than if it were diversified
broadly over numerous industries and sectors of the economy. At times, such
industry or group of industries may be out of favor and underperform other
industries or the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Intellidex for a number of reasons. For example, the Fund incurs
operating expenses not applicable to the Underlying Intellidex, and incurs costs
in buying and selling securities, especially when rebalancing the Fund's
securities holdings to reflect changes in the composition of the Underlying
Intellidex. In addition, the performance of the Fund and the Underlying
Intellidex may vary due to asset valuation differences and differences between
the Fund's portfolio and the Underlying Intellidex resulting from legal
restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Intellidex.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Intellidex, even if that
security generally is underperforming.

Small and Medium Capitalization Company Risk. Investing in securities of small
and medium capitalization companies involves greater risk than customarily is
associated with investing in larger, more established companies. These
companies' securities may be more volatile and less liquid than those of more
established companies. These securities may have returns that vary, sometimes
significantly, from the overall securities market. Often small and medium capitalization
companies and the industries in which they focus are still evolving and, as a result,
they may be more sensitive to changing market conditions.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC
or any other government agency.

Performance

The bar chart below shows how the Fund has performed. The table below the bar
chart shows the Fund's average annual total returns (before and after taxes).
The bar chart and table provide an indication of the risks of investing in the
Fund by showing how the Fund's total return has varied from year to year and by
showing how the Fund's average annual total returns compared with a broad
measure of market performance. The Fund's performance reflects fee waivers, if
any, absent which, performance would have been lower. Although the information
shown in the bar chart and the table gives you some idea of the risks involved
in investing in the Fund, the Fund's past performance (before and after taxes)
is not necessarily indicative of how the Fund will perform in the future.

The Fund generally will invest at least 90% of its total assets in common stocks that comprise the Underlying Index. As of June 30, 2011, the Underlying Index was composed of stocks of approximately 52 U.S. companies whose shares are listed on the New York Stock Exchange ("NYSE"), NYSE Amex or the NASDAQ Stock Market, LLC ("NASDAQ"). These companies are engaged principally in the research, development, manufacture, operation and support of defense, military, homeland security and space operations. These may include, for example, companies that provide the following products or services: defense electronics, aircraft, naval vessels, missiles, spacecraft and launch vehicles, ground vehicles, communications, sensors, information technology and network centric warfare, unmanned vehicles, satellite-based services and ground-based equipment and electronics. Strictly in accordance with its existing guidelines and mandated procedures, ISBC, LLC ("ISBC" or the "Index Provider") identifies stocks for the Underlying Index.

Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. Aerospace and Defense Industry Concentration Risk. Government aerospace and defense regulation and spending policies can significantly affect the aerospace and defense industry because many companies involved in the aerospace and defense industry rely to a large extent on U.S. (and other) Government demand for their products and services. There are significant inherent risks in contracting with the U.S. Government that could have a material adverse effect on the business, financial condition and results of operations of industry participants. Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Index is comprised of issuers in a single industry or sector of the economy. By focusing in an industry or sector, the Fund faces more risks than if it were diversified broadly over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries or the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Index resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming. Small and Medium Capitalization Company Risk. Investing in securities of small and medium capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Often small and medium capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund's volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund's performance. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC or any other government agency.

[1] Invesco PowerShares Capital Management LLC (the "Adviser") has agreed to waive fees and/or pay Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, brokerage commissions and other trading expenses, sub-licensing fees, offering costs, taxes and extraordinary expenses) from exceeding 0.60% of the Fund's average daily net assets per year (the "Expense Cap") until at least August 31, 2012, and neither the Adviser nor the Fund can discontinue the agreement prior to its expiration. The expenses borne by the Adviser are subject to recapture by the Adviser for up to three years from the date the fee or expense was borne by the Adviser, but no recapture payment will be made by the Fund if it would result in the Fund exceeding its Expense Cap.

PowerShares Lux Nanotech Portfolio (Prospectus Summary) | PowerShares Lux Nanotech Portfolio

PowerShares Lux Nanotech Portfolio

Investment Objective

The PowerShares Lux Nanotech Portfolio (the "Fund") seeks investment results
that generally correspond (before fees and expenses) to the price and yield of
the Lux Nanotech IndexTM (the "Underlying Index").

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors may pay brokerage commissions on their
purchases and sales of Shares, which are not reflected in the table or the
example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		PowerShares Lux Nanotech Portfolio
Management Fees		0.50%
Other Expenses		0.15%
Acquired Fund Fees and Expenses	[1]	0.30%
Total Annual Fund Operating Expenses		0.95%
Fee Waivers and Expense Assumption	[2]	0.25%
Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption	[2]	0.70%

Example

This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. This example assumes that you invest
$10,000 in the Fund for the time periods indicated and then sell all of your
Shares at the end of those periods. The example also assumes that your investment
has a 5% return each year and that the Fund's operating expenses remain the same.
The cost under the one year example is equal to the Total Annual Fund Operating
Expenses After Fee Waivers and Expense Assumption in the first year and the Total
Annual Fund Operating Expenses thereafter. This example does not include the
brokerage commissions that investors may pay to buy and sell Shares of the Fund.

Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Expense Example (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
PowerShares Lux Nanotech Portfolio	72	278	501	1,144

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover was 58% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 80% of its total assets in common stocks
of nanotechnology companies. A nanotechnology company focuses on the development
and use of devices that are only a few nanometers in size. The Fund generally
will invest at least 90% of its total assets in common stocks that comprise the
Underlying Index. The Underlying Index is a modified equal dollar weighted index
that, as of June 30, 2011, was composed of stocks of approximately 21 publicly
traded companies in the nanotechnology field. Strictly in accordance with its
existing guidelines and mandated procedures, Lux Research, Inc ("Lux" or the
"Index Provider") includes companies in the nanotechnology field that are
involved with funding nanotechnology development, developing nanotechnology
applications, manufacturing goods that incorporate those applications and/or
supplying tools and instrumentation to nanotechnology researchers. As of June
30, 2011, the Underlying Index included common stocks of companies with a market
capitalization range of between approximately $80 million and $205 billion.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying Index
reflects a concentration in that industry or group of industries. The Fund will
not otherwise concentrate its investments in securities of issuers in any one
industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Nanotechnology Industry Concentration Risk. Small technology companies are
especially risky. These companies may be less experienced, with limited product
lines, markets or financial resources. Consequently, these companies are subject
to scientific, technological and commercialization risks. These securities have
a significantly greater risk of loss than traditional investment securities due
to the speculative nature of these investments. Technology companies generally
are subject to the risk of rapidly changing technologies, a limited product life
span due to the frequent introduction of new or improved products, as well as
cyclical market patterns and evolving industry standards. Technology companies
also face the risk of losing patent, copyright and trademark protections.

Sampling Risk. The Fund's use of a representative sampling approach will result
in its holding a smaller number of securities than are in the Underlying Index.
As a result, an adverse development respecting an issuer of securities held by
the Fund could result in a greater decline in NAV than would be the case if the
Fund held all of the securities in the Underlying Index. To the extent the
assets in the Fund are smaller, these risks will be greater.

Market Risk. Securities in the Underlying Index are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Index.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets, and disruption in the creation/redemption process of the
Fund. Any of these factors may lead to the Shares trading at a premium or
discount to the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or debt
instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Index is
comprised of issuers in a single industry or sector of the economy. By focusing
in an industry or sector, the Fund faces more risks than if it were diversified
broadly over numerous industries and sectors of the economy. At times, such
industry or group of industries may be out of favor and underperform other
industries or the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Index for a number of reasons. For example, the Fund incurs operating
expenses not applicable to the Underlying Index, and incurs costs in buying and
selling securities, especially when rebalancing the Fund's securities holdings
to reflect changes in the composition of the Underlying Index. In addition, the
performance of the Fund and the Underlying Index may vary due to asset valuation
differences and differences between the Fund's portfolio and the Underlying
Index resulting from legal restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Index.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Index, even if that
security generally is underperforming.

Small Capitalization Company Risk. Investing in securities of small
capitalization companies involves greater risk than customarily is associated
with investing in larger, more established companies. These companies'
securities may be more volatile and less liquid than those of more established
companies. These securities may have returns that vary, sometimes significantly,
from the overall securities market. Often small capitalization companies and the
industries in which they focus are still evolving and, as a result, they may be
more sensitive to changing market conditions.

Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater
portion of its assets in securities of individual issuers than a diversified
fund. As a result, changes in the market value of a single investment could
cause greater fluctuations in Share price than would occur in a diversified
fund. This may increase the Fund's volatility and cause the performance of a
relatively small number of issuers to have a greater impact on the Fund's
performance.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC
or any other government agency.

Performance

The bar chart below shows how the Fund has performed. The table below the bar
chart shows the Fund's average annual total returns (before and after taxes).
The bar chart and table provide an indication of the risks of investing in the
Fund by showing how the Fund's total return has varied from year to year and by
showing how the Fund's average annual total returns compared with a broad
measure of market performance. The Fund's performance reflects fee waivers, if
any, absent which, performance would have been lower. Although the information
shown in the bar chart and the table gives you some idea of the risks involved
in investing in the Fund, the Fund's past performance (before and after taxes)
is not necessarily indicative of how the Fund will perform in the future.

After-tax returns in the table below are calculated using the historical highest
individual federal marginal income tax rates and do not reflect the impact of
state and local taxes. Actual after-tax returns depend on an investor's tax
situation and may differ from those shown, and after-tax returns shown are not
relevant to investors who hold Shares through tax-deferred arrangements, such as
401(k) plans or individual retirement accounts. In the event of negative
performance displayed in the table below, the Fund's returns after taxes on
distributions and sale of Fund Shares are calculated assuming that an investor
has sufficient capital gains of the same character from other investments to
offset any capital losses from the sale of Fund Shares so that the investor may
deduct the losses in full. As a result, the Fund's returns after taxes on
distributions and sale of Fund Shares may exceed the Fund's returns before taxes
and/or returns after taxes on distributions.

[1] Acquired Fund Fees and Expenses are indirect fees and expenses that the Fund incurs from investing in the shares of other investment companies. Please note that the amount of Total Annual Fund Operating Expenses shown in the above table may differ from the ratio of expenses prior to waivers and/or recapture to average net assets included in the "Financial Highlights" section of this Prospectus, which reflects the operating expenses of the Fund and does not include indirect expenses such as Acquired Fund Fees and Expenses.

[2] Invesco PowerShares Capital Management LLC (the "Adviser") has agreed to waive fees and/or pay Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, brokerage commissions and other trading expenses, sub-licensing fees, offering costs, taxes and extraordinary expenses) from exceeding 0.60% of the Fund's average daily net assets per year (the "Expense Cap") until at least August 31, 2012, and neither the Adviser nor the Fund can discontinue the agreement prior to its expiration. The expenses borne by the Adviser are subject to recapture by the Adviser for up to three years from the date the fee or expense was borne by the Adviser, but no recapture payment will be made by the Fund if it would result in the Fund exceeding its Expense Cap.

PowerShares Dynamic Food & Beverage Portfolio (Prospectus Summary) | PowerShares Dynamic Food & Beverage Portfolio

PowerShares Dynamic Food & Beverage Portfolio

Investment Objective

The PowerShares Dynamic Food & Beverage Portfolio (the "Fund") seeks investment
results that generally correspond (before fees and expenses) to the price and
yield of the Dynamic Food & Beverage IntellidexSM Index (the "Underlying
Intellidex").

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors may pay brokerage commissions on their
purchases and sales of Shares, which are not reflected in the table or the
example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		PowerShares Dynamic Food & Beverage Portfolio
Management Fees		0.50%
Other Expenses		0.21%
Total Annual Fund Operating Expenses		0.71%
Fee Waivers and Expense Assumption	[1]	0.08%
Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption	[1]	0.63%

Example

This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. This example assumes that you invest
$10,000 in the Fund for the time periods indicated and then sell all of your
Shares at the end of those periods. The example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. The cost under the one year example is equal to the Total
Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the
first year and the Total Annual Fund Operating Expenses thereafter. This example
does not include the brokerage commissions that
investors may pay to buy and sell Shares of the Fund.

Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Expense Example (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
PowerShares Dynamic Food & Beverage Portfolio	64	219	387	875

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover rate was 73% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 80% of its total assets in common stocks
of food and beverage companies. The Fund generally will invest at least 90% of
its total assets in common stocks that comprise the Underlying Intellidex. As of
June 30, 2011, the Underlying Intellidex was composed of stocks of 30 U.S. food
and beverage companies. These companies are engaged principally in the
manufacture, sale or distribution of food and beverage products, agricultural
products and products related to the development of new food technologies. These
companies may include, for example, companies that sell products and services,
such as meat and poultry processing and wholesale and retail distribution, and
warehousing of food and food-related products, including restaurants, grocery
stores, brewers, distillers and vintners; and companies that manufacture and
distribute products including soft drinks, packaged food products (such as
cereals, pet foods, and frozen foods), health food and dietary products.
Strictly in accordance with its existing guidelines and mandated procedures, the
Intellidex Provider includes stocks principally on the basis of their capital
appreciation potential that it identifies pursuant to a proprietary Intellidex
methodology. As of June 30, 2011, the Underlying Intellidex included common
stocks of companies with a market capitalization range of between approximately
$434 million and $154 billion.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying
Intellidex reflects a concentration in that industry or group of industries. The
Fund will not otherwise concentrate its investments in securities of issuers in
any one industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Food and Beverage Industry Concentration Risk. The food and beverage industry is
highly competitive and can be significantly affected by demographic and product
trends, competitive pricing, food fads, marketing campaigns, environmental
factors, government regulation, adverse changes in general economic conditions,
evolving consumer preferences, nutritional and health-related concerns, federal,
state and local food inspection and processing controls, consumer product
liability claims, consumer boycotts, risks of product tampering and the
availability and expense of liability insurance.

Market Risk. Securities in the Underlying Intellidex are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Intellidex.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets, and disruption in the creation/redemption process of the
Fund. Any of these factors may lead to the Shares trading at a premium or
discount to the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or debt
instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Intellidex is
comprised of issuers in a single industry or sector of the economy. By focusing
in an industry or sector, the Fund faces more risks than if it were diversified
broadly over numerous industries and sectors of the economy. At times, such
industry or group of industries may be out of favor and underperform other
industries or the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Intellidex for a number of reasons. For example, the Fund incurs
operating expenses not applicable to the Underlying Intellidex, and incurs costs
in buying and selling securities, especially when rebalancing the Fund's
securities holdings to reflect changes in the composition of the Underlying
Intellidex. In addition, the performance of the Fund and the Underlying
Intellidex may vary due to asset valuation differences and differences between
the Fund's portfolio and the Underlying Intellidex resulting from legal
restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Intellidex.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Intellidex, even if that
security generally is underperforming.

Small and Medium Capitalization Company Risk. Investing in securities of small
and medium capitalization companies involves greater risk than customarily is
associated with investing in larger, more established companies. These
companies' securities may be more volatile and less liquid than those of more
established companies. These securities may have returns that vary, sometimes
significantly, from the overall securities market. Often small and medium
capitalization companies and the industries in which they focus are still
evolving and, as a result, they may be more sensitive to changing market
conditions.

Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater
portion of its assets in securities of individual issuers than a diversified
fund. As a result, changes in the market value of a single investment could cause
greater fluctuations in Share price than would occur in a diversified fund.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC
or any other government agency.

PowerShares International Dividend Achievers Portfolio (Prospectus Summary) | PowerShares International Dividend Achievers Portfolio

PowerShares International Dividend AchieversTM Portfolio

Investment Objective

The PowerShares International Dividend AchieversTM Portfolio (the "Fund") seeks
investment results that generally correspond (before fees and expenses) to the
price and yield of the International Dividend AchieversTM Index (the "Underlying
Index").

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors may pay brokerage commissions on their
purchases and sales of Shares, which are not reflected in the table or the
example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		PowerShares International Dividend Achievers Portfolio
Management Fees		0.40%
Other Expenses		0.18%
Total Annual Fund Operating Expenses		0.58%
Fee Waivers and Expense Assumption	[1]	none
Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption	[1]	0.58%

Example

This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. This example assumes that you invest
$10,000 in the Fund for the time periods indicated and then sell all of your
Shares at the end of those periods. The example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. The cost under the one year example is equal to the Total
Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the
first year and the Total Annual Fund Operating Expenses thereafter. This example
does not include the brokerage commissions that investors may pay to buy and
sell Shares of the Fund.

Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Expense Example (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
PowerShares International Dividend Achievers Portfolio	59	186	324	726

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover rate was 42% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 90% of its total assets in the
securities that comprise the International Dividend AchieversTM Index. The
Underlying Index currently is composed of global depositary receipts ("GDRs")
and American depositary receipts ("ADRs") that are listed on the London Stock
Exchange ("LSE"), in addition to ADRs and non-U.S. common or ordinary stocks
traded on the New York Stock Exchange ("NYSE"), the NASDAQ Stock Market LLC
("NASDAQ") or NYSE Amex of companies that have increased their aggregate annual
regular dividend payments consistently over the course of the last five calendar
or fiscal years. Strictly in accordance with its existing guidelines and
mandated procedures, Mergent®, Inc. ("Mergent" or the "Index Provider") includes
stock in the Underlying Index pursuant to a proprietary selection methodology.
As of June 30, 2011, the Underlying Index was composed of approximately 64
securities selected principally on the basis of their consecutive years of
dividend growth with a market capitalization range of between approximately $135
million and $216 billion.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying Index
reflects a concentration in that industry or group of industries. The Fund will
not otherwise concentrate its investments in securities of issuers in any one
industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Dividend Paying Security Risk. Securities that pay high dividends as a group can
fall out of favor with the market, causing such companies to underperform
companies that do not pay high dividends. Also changes in the dividend policies
of the companies in the Underlying Index and the capital resources available for
such companies' dividend payments may affect the Fund.

Financial Sector Risk. The market value of securities of issuers in the
financial sector can be affected by factors such as adverse regulatory or
economic occurrences affecting the financial sector, availability of credit,
fluctuations in asset values, unstable interest rates, increased competition,
continuing consolidations and development of new products and structures.
Furthermore, increased government involvement in financial institutions, including
measures such as taking ownership positions in such institutions, could result in
a dilution in the value of the shares held by shareholders in such institutions.

Foreign Securities Risk. The Fund's investments in foreign securities involve
risks that are in addition to the risks associated with domestic securities.
Foreign companies, in general, are not subject to the regulatory requirements of
U.S. companies and, as such, there may be less publicly available information
about these companies. Moreover, foreign companies are often subject to less
stringent requirements regarding accounting, auditing, financial reporting and
record-keeping than are U.S. companies, and therefore, not all material
information regarding these companies will be available.

Market Risk. Securities in the Underlying Index are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Index.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets, and disruption in the creation/redemption process of the
Fund. Any of these factors may lead to the Shares trading at a premium or
discount to the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or debt
instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Index may be
composed of issuers in a single industry or sector of the economy. If the Fund
is focused in an industry or sector, it may present more risks than if it were
diversified broadly over numerous industries and sectors of the economy. At
times, such industry or group of industries may be out of favor and underperform
other industries or the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Index for a number of reasons. For example, the Fund incurs operating
expenses not applicable to the Underlying Index, and incurs costs in buying and
selling securities, especially when rebalancing the Fund's securities holdings
to reflect changes in the composition of the Underlying Index. In addition, the
performance of the Fund and the Underlying Index may vary due to asset valuation
differences and differences between the Fund's portfolio and the Underlying
Index resulting from legal restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Index.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Index, even if that security
generally is underperforming.

Small and Medium Capitalization Company Risk. Investing in securities of small
and medium capitalization companies involves greater risk than customarily is
associated with investing in larger, more established companies. These
companies' securities may be more volatile and less liquid than those of more
established companies. These securities may have returns that vary, sometimes
significantly, from the overall securities market. Often small and medium
capitalization companies and the industries in which they focus are still
evolving and, as a result, they may be more sensitive to changing market
conditions.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC
or any other government agency.

Performance

The bar chart below shows how the Fund has performed. The table below the bar
chart shows the Fund's average annual total returns (before and after taxes).
The bar chart and table provide an indication of the risks of investing in the
Fund by showing how the Fund's total return has varied from year to year and by
showing how the Fund's average annual total returns compared with a broad
measure of market performance. The Fund's performance reflects fee waivers, if
any, absent which, performance would have been lower. Although the information
shown in the bar chart and the table gives you some idea of the risks involved
in investing in the Fund, the Fund's past performance (before and after taxes)
is not necessarily indicative of how the Fund will perform in the future.

("NYSE Arca" or the "Intellidex Provider") considers a company to be a large capitalization company if it falls within the Underlying Intellidex model, as described below. The Fund generally will invest at least 90% of its total assets in common stocks that comprise the Underlying Intellidex. As of June 30, 2011, the Underlying Intellidex was composed of 50 large capitalization U.S. value stocks that, strictly in accordance with its existing guidelines and mandated procedures, NYSE Arca included principally on the basis of their capital appreciation potential that NYSE Arca identifies pursuant to a proprietary Intellidex methodology. As of June 30, 2011, the Underlying Intellidex included common stocks of companies with a market capitalization range of between approximately $12 billion and $396 billion. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Intellidex reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.

Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. Value Investing Style Risk. "Value" securities are subject to the risk that the valuations never improve or that the returns on "value" securities are less than returns on other styles of investing or the overall stock market. Thus, the value of the Fund's investments will vary and, at times, may be lower or higher than that of other types of investments. Market Risk. Securities in the Underlying Intellidex are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Intellidex. Market Trading Risk. The Fund faces market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Intellidex may be composed of issuers in a single industry or sector of the economy. If the Fund is focused in an industry or sector, it may present more risks than if it were diversified broadly over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries or the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Intellidex for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Intellidex, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Intellidex. In addition, the performance of the Fund and the Underlying Intellidex may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Intellidex resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Intellidex. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Intellidex, even if that security generally is underperforming. Large Capitalization Company Risk. Companies with large market capitalizations may go in and out of favor based on market and economic conditions. Although larger companies tend to be less volatile than companies with smaller market capitalizations, returns on investments in securities of large capitalization U.S. companies could trail the returns on investments in stocks of smaller companies. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC or any other government agency.

[1] Invesco PowerShares Capital Management LLC (the "Adviser") has agreed to waive fees and/or pay Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, brokerage commissions and other trading expenses, sub-licensing fees, offering costs, taxes and extraordinary expenses) from exceeding 0.60% of the Fund's average daily net assets per year (the "Expense Cap") until at least August 31, 2012, and neither the Adviser nor the Fund can discontinue the agreement prior to its expiration. The expenses borne by the Adviser are subject to recapture by the Adviser for up to three years from the date the fee or expense was borne by the Adviser, but no recapture payment will be made by the Fund if it would result in the Fund exceeding its Expense Cap.

Investment Strategy, Heading	rr_StrategyHeading	Principal Investment Strategies
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 80% of its total assets in common stocks of companies that have raised their annual regular cash dividend payments for at least each of the last ten fiscal years. The Fund generally will invest at least 90% of its total assets in dividend-paying common stocks that comprise the Underlying Index. Strictly in accordance with its existing guidelines and mandated procedures, Mergent®, Inc. ("Mergent" or the "Index Provider") includes stock in the Underlying Index pursuant to a proprietary selection methodology. As of June 30, 2011, the Underlying Index was composed of stocks of approximately 190 companies with a market capitalization range of between approximately $289 million and $400 million. To qualify for the universe of "Dividend AchieversTM," an issuer must have increased its annual regular cash dividend payments for each of its last ten fiscal years. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Investment Strategy, Portfolio Concentration	rr_StrategyPortfolioConcentration	The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. Dividend Paying Security Risk. Securities that pay high dividends as a group can fall out of favor with the market, causing such companies to underperform companies that do not pay high dividends. Also changes in the dividend policies of the companies in the Underlying Index and the capital resources available for such companies' dividend payments may affect the Fund. Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Index may be composed of issuers in a single industry or sector of the economy. If the Fund is focused in an industry or sector, it may present more risks than if it were diversified broadly over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries or the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Index resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming. Small and Medium Capitalization Company Risk. Investing in securities of small and medium capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Often small and medium capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC or any other government agency.

PowerShares Financial Preferred Portfolio (Prospectus Summary) | PowerShares Financial Preferred Portfolio

PowerShares Financial Preferred Portfolio

Investment Objective

The PowerShares Financial Preferred Portfolio (the "Fund") seeks investment
results that generally correspond (before fees and expenses) to the price and
yield of the Wells Fargo® Hybrid & Preferred Securities Financial Index (the
"Underlying Index").

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors may pay brokerage commissions on their
purchases and sales of Shares, which are not reflected in the table or the
example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		PowerShares Financial Preferred Portfolio
Management Fees		0.50%
Other Expenses		0.16%
Total Annual Fund Operating Expenses		0.66%
Fee Waivers and Expense Assumption	[1]	none
Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption	[1]	0.66%

Example

This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. This example assumes that you invest
$10,000 in the Fund for the time periods indicated and then sell all of your
Shares at the end of those periods. The example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. The cost under the one year example is equal to the Total
Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the
first year and the Total Annual Fund Operating Expenses thereafter. This example
does not include the brokerage commissions that investors may pay to buy and sell
Shares of the Fund.

Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Expense Example (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
PowerShares Financial Preferred Portfolio	67	211	368	822

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover rate was 26% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 80% of its total assets in preferred
securities of financial institutions. The Fund generally will invest at least
90% of its total assets in preferred securities that comprise the Underlying
Index. The Underlying Index is a market capitalization weighted index designed
to track the performance of preferred securities issued in the U.S. market by
financial institutions. As of June 30, 2011, the Underlying Index was composed
of preferred securities of approximately 22 financial institutions that have
received an industrial sector classification of "financial" from the Bloomberg
Professional Service. Strictly in accordance with its existing guidelines and
mandated procedures, Wells Fargo Securities, LLC (together with Wells Fargo &
Company, the "Index Provider") includes securities in the Underlying Index
pursuant to a proprietary selection methodology. As of June 30, 2011, the
Underlying Index included companies with a market capitalization range of
between approximately $4 billion and $150 billion. Preferred securities have a
payment priority over common stock in the payment of specified dividends and in
the event of the issuer's liquidation. Dividends generally are paid on a fixed
rate percentage of the fixed par value at which the preferred stock is issued,
and preferred stocks generally have a liquidation value that equals the original
purchase price of the stock at the time of issuance.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying Index
reflects a concentration in that industry or group of industries. The Fund will
not otherwise concentrate its investments in securities of issuers in any one
industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Financial Sector Risk. The market value of securities of issuers in the
financial sector can be affected by factors such as adverse regulatory or
economic occurrences affecting the financial sector, availability of credit,
fluctuations in asset values, unstable interest rates, increased competition,
continuing consolidations and development of new products and structures.
Furthermore, increased government involvement in financial institutions,
including measures such as taking ownership positions in such institutions,
could result in a dilution in the value of the shares held by shareholders in
such institutions.

Foreign Financial Institution Risk. Certain of the companies that comprise the
Underlying Index, while traded on U.S. exchanges, may be issued by foreign
financial institutions. Therefore, the Fund may be subject to the risks of
investing in securities issued by foreign companies.

High Yield Securities Risk. High yield securities typically involve greater risk
and are less liquid than higher grade issues. Changes in general economic
conditions, changes in the financial condition of the issuers and changes in
interest rates may adversely impact the ability of issuers of high yield
securities to make timely payments of interest and principal.

Preferred Securities Risk. There are special risks associated with investing in
preferred securities. Preferred securities may include provisions that permit
the issuer, in its discretion, to defer or omit distributions for a certain
period of time. If the Fund owns a security that is deferring or omitting its
distributions, the Fund may be required to report the distribution on its tax
returns, even though it may not have received any income. Further, preferred
securities may lose substantial value due to the omission or deferment of
dividend payments. Preferred securities may be less liquid than many other
securities, such as common stocks, and generally offer no voting rights with
respect to the issuer. Preferred securities also may be subordinated to bonds or
other debt instruments in an issuer's capital structure, subjecting them to a
greater risk of non-payment than more senior securities. In addition, in certain
circumstances, an issuer of preferred securities may redeem the securities prior
to a specified date, and this may negatively impact the return of the security.

Market Risk. Securities in the Underlying Index are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Index.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets, and disruption in the creation/redemption process of the
Fund. Any of these factors may lead to the Shares trading at a premium or
discount to the Fund's net asset value ("NAV").

Concentration Risk. A significant percentage of the Underlying Index may be
composed of issuers in a single industry or sector of the economy. If the Fund
is focused in an industry or sector, it may present more risks than if it were
diversified broadly over numerous industries and sectors of the economy. At
times, such industry or group of industries may be out of favor and underperform
other industries or the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Index for a number of reasons. For example, the Fund incurs operating
expenses not applicable to the Underlying Index, and incurs costs in buying and
selling securities, especially when rebalancing the Fund's securities holdings
to reflect changes in the composition of the Underlying Index. In addition, the
performance of the Fund and the Underlying Index may vary due to asset valuation
differences and differences between the Fund's portfolio and the Underlying
Index resulting from legal restrictions, cost or liquidity constraints. For
example, because the Fund's Underlying Index does not meet the diversification
requirements set forth in the Internal Revenue Code relating to regulated
investment companies, the Fund may not be able to invest in all of the stocks
comprising its Underlying Index in proportion to their weightings in the
Underlying Index at all times.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Index.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Index, even if that
security generally is underperforming.

Small and Medium Capitalization Company Risk. Investing in securities of small
and medium capitalization companies involves greater risk than customarily is
associated with investing in larger, more established companies. These
companies' securities may be more volatile and less liquid than those of more
established companies.  These securities may have returns that vary, sometimes
significantly, from the overall securities market. Often small and medium
capitalization companies and the industries in which they focus are still
evolving and, as a result, they may be more sensitive to changing market conditions.

Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater
portion of its assets in securities of individual issuers than a diversified
fund. As a result, changes in the market value of a single investment could
cause greater fluctuations in Share price than would occur in a diversified
fund. This may increase the Fund's volatility and cause the performance of a
relatively small number of issuers to have a greater impact on the Fund's
performance.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC
or any other government agency.

Performance

The bar chart below shows how the Fund has performed. The table below the bar
chart shows the Fund's average annual total returns (before and after taxes).
The bar chart and table provide an indication of the risks of investing in the
Fund by showing how the Fund's total return has varied from year to year and by
showing how the Fund's average annual total returns compared with a broad
measure of market performance. The Fund's performance reflects fee waivers, if
any, absent which, performance would have been lower. Although the information
shown in the bar chart and the table gives you some idea of the risks involved
in investing in the Fund, the Fund's past performance (before and after taxes)
is not necessarily indicative of how the Fund will perform in the future.

PowerShares Dynamic Consumer Staples Sector Portfolio (Prospectus Summary) | PowerShares Dynamic Consumer Staples Sector Portfolio

Dynamic Consumer Staples Sector Portfolio

Investment Objective

The PowerShares Dynamic Consumer Staples Sector Portfolio (the "Fund") seeks
investment results that generally correspond (before fees and expenses) to the
price and yield of the Dynamic Consumer Staples Sector IntellidexSM Index (the
"Underlying Intellidex").

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors may pay brokerage commissions on their
purchases and sales of Shares, which are not reflected in the table or the
example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		PowerShares Dynamic Consumer Staples Sector Portfolio
Management Fees		0.50%
Other Expenses		0.44%
Total Annual Fund Operating Expenses		0.94%
Fee Waivers and Expense Assumption	[1]	0.29%
Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption	[1]	0.65%

Example

This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. This example assumes that you invest
$10,000 in the Fund for the time periods indicated and then sell all of your
Shares at the end of those periods. The example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. The cost under the one year example is equal to the Total
Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the
first year and the Total Annual Fund Operating Expenses thereafter. This example
does not include the brokerage commissions that investors may pay to buy and sell
Shares of the Fund.

Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Expense Example (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
PowerShares Dynamic Consumer Staples Sector Portfolio	65	270	491	1,127

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover was 54% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 80% of its total assets in common stocks
of consumer companies. The Fund generally will invest at least 90% of its total
assets in common stocks that comprise the Underlying Intellidex. As of June 30,
2011, the Underlying Intellidex was comprised of stocks of 60 U.S. consumer
companies. These companies are principally engaged in the businesses of
providing consumer goods and services that have non-cyclical characteristics,
including tobacco, textiles, food and beverage, and non-discretionary retail.
Strictly in accordance with its existing guidelines and mandated procedures,
NYSE Arca, Inc. ("NYSE Arca" or the "Intellidex Provider") includes stocks
principally on the basis of their capital appreciation potential that it
identifies pursuant to a proprietary Intellidex methodology. As of June 30,
2011, the Underlying Intellidex included common stocks of companies with a
market capitalization range of between $431 million and $183 billion.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying
Intellidex reflects a concentration in that industry or group of industries. The
Fund will not otherwise concentrate its investments in securities of issuers in
any one industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Consumer Staples Sector Risk. Changes in the worldwide economy, consumer
spending, competition, demographics and consumer preferences, exploration and
production spending may adversely affect companies in the consumer staples
sector. Companies in this sector also are affected by changes in government
regulation, world events and economic conditions.

Market Risk. Securities in the Underlying Intellidex are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Intellidex.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets and disruption in the creation/redemption process of the Fund.
Any of these factors may lead to the Shares trading at a premium or discount to
the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or debt
instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Intellidex is
comprised of issuers in a single industry or sector of the economy. By focusing
in an industry or sector, the Fund faces more risks than if it were diversified
broadly over numerous industries and sectors of the economy. At times, such
industry or group of industries may be out of favor and underperform other
industries or the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Intellidex for a number of reasons. For example, the Fund incurs
operating expenses not applicable to the Underlying Intellidex, and incurs costs
in buying and selling securities, especially when rebalancing the Fund's
securities holdings to reflect changes in the composition of the Underlying
Intellidex. In addition, the performance of the Fund and the Underlying
Intellidex may vary due to asset valuation differences and differences between
the Fund's portfolio and the Underlying Intellidex resulting from legal
restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Intellidex.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Intellidex, even if that
security generally is underperforming.

Small and Medium Capitalization Company Risk. Investing in securities of small
and medium capitalization companies involves greater risk than customarily is
associated with investing in larger, more established companies. These
companies' securities may be more volatile and less liquid than those of more
established companies. These securities may have returns that vary, sometimes
significantly, from the overall securities market. Often small and medium
capitalization companies and the industries in which they focus are still
evolving and, as a result, they may be more sensitive to changing market
conditions.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC
or any other government agency.

The bar chart and table provide an indication of the risks of investing in the
Fund by showing how the Fund's total return has varied from year to year and by
showing how the Fund's average annual total returns compared with a broad
measure of market performance. The Fund's performance reflects fee waivers, if
any, absent which, performance would have been lower. Although the information
shown in the bar chart and the table gives you some idea of the risks involved
in investing in the Fund, the Fund's past performance (before and after taxes)
is not necessarily indicative of how the Fund will perform in the future.

Fund will not otherwise concentrate its investments in securities of issuers in
any one industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Consumer Discretionary Sector Risk. Companies engaged in the consumer
discretionary sector are affected by fluctuations in supply and demand. Changes
in consumer spending as a result of world events, political and economic
conditions, commodity price volatility, changes in exchange rates, imposition of
import controls, increased competition, depletion of resources and labor
relations also may adversely affect these companies.

Market Risk. Securities in the Underlying Intellidex are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Intellidex.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in

You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Intellidex. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Intellidex is comprised of issuers in a single industry or sector of the economy. By focusing in an industry or sector, the Fund faces more risks than if it were diversified broadly over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries or the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Intellidex for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Intellidex, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Intellidex. In addition, the performance of the Fund and the Underlying Intellidex may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Intellidex resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Intellidex. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Intellidex, even if that security generally is underperforming. Small and Medium Capitalization Company Risk. Investing in securities of small and medium capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Often small and medium capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund's volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund's performance. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC or any other government agency.

PowerShares Dynamic Leisure & Entertainment Portfolio (Prospectus Summary) | PowerShares Dynamic Leisure & Entertainment Portfolio

PowerShares Dynamic Leisure and Entertainment Portfolio

Investment Objective

The PowerShares Dynamic Leisure and Entertainment Portfolio (the "Fund") seeks
investment results that generally correspond (before fees and expenses) to the
price and yield of the Dynamic Leisure and Entertainment IntellidexSM Index (the
"Underlying Intellidex").

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors may pay brokerage commissions on their
purchases and sales of Shares, which are not reflected in the table or the
example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		PowerShares Dynamic Leisure & Entertainment Portfolio
Management Fees		0.50%
Other Expenses		0.28%
Total Annual Fund Operating Expenses		0.78%
Fee Waivers and Expense Assumption	[1]	0.15%
Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption	[1]	0.63%

Example

This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. This example assumes that you invest
$10,000 in the Fund for the time periods indicated and then sell all of your
Shares at the end of those periods. The example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. The cost under the one year example is equal to the Total
Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the
first year and the Total Annual Fund Operating Expenses thereafter. This example
does not include the brokerage commissions that investors may pay to buy and
sell Shares of the Fund.

Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Expense Example (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
PowerShares Dynamic Leisure & Entertainment Portfolio	64	234	419	952

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover rate was 58% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 80% of its total assets in common stocks
of leisure companies and entertainment companies. The Fund generally will invest
at least 90% of its total assets in common stocks that comprise the Underlying
Intellidex. As of June 30, 2011, the Underlying Intellidex was composed of
stocks of 30 U.S. leisure and entertainment companies. These companies are
engaged principally in the design, production or distribution of goods or
services in the leisure and entertainment industries. These companies may
include, for example, companies that provide goods or services, including
television and radio broadcast or manufacture (including cable television);
motion pictures and photography; recordings and musical instruments; publishing,
including newspapers and magazines; sporting goods and camping and recreational
equipment; toys and games, including video and other electronic games; amusement
and theme parks; travel and travel-related services; leisure apparel or
footwear; and owners and operators of sports arenas and gaming casinos, hotels
and motels. Strictly in accordance with its existing guidelines and mandated
procedures, the Intellidex Provider includes stocks principally on the basis of
their capital appreciation potential that it identifies pursuant to a
proprietary Intellidex methodology. As of June 30, 2011, the Underlying
Intellidex included common stocks of companies with a market capitalization
range of between approximately $377 million and $87 billion.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying
Intellidex reflects a concentration in that industry or group of industries. The
Fund will not otherwise concentrate its investments in securities of issuers in
any one industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Leisure and Entertainment Industries Concentration Risk. Companies engaged in
the design, production, or distribution of goods or services for the leisure and
entertainment industries (including sports arenas, amusement and theme parks,
gaming casinos, sporting goods, camping and recreational equipment, toys and
games, travel-related services, hotels and motels and fast food and other
restaurants) may become obsolete quickly. Additionally, several factors can
significantly affect the leisure and entertainment industries, including the
performance of the overall economy, changing consumer tastes and discretionary
income levels, intense competition, technological developments and government
regulation.

Market Risk. Securities in the Underlying Intellidex are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Intellidex.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets, and disruption in the creation/redemption process of the
Fund. Any of these factors may lead to the Shares trading at a premium or
discount to the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or debt
instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Intellidex is
comprised of issuers in a single industry or sector of the economy. By focusing
in an industry or sector, the Fund faces more risks than if it were diversified
broadly over numerous industries and sectors of the economy. At times, such
industry or group of industries may be out of favor and underperform other
industries or the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Intellidex for a number of reasons. For example, the Fund incurs
operating expenses not applicable to the Underlying Intellidex, and incurs costs
in buying and selling securities, especially when rebalancing the Fund's
securities holdings to reflect changes in the composition of the Underlying
Intellidex. In addition, the performance of the Fund and the Underlying
Intellidex may vary due to asset valuation differences and differences between
the Fund's portfolio and the Underlying Intellidex resulting from legal
restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Intellidex.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Intellidex, even if that
security generally is underperforming.

Small and Medium Capitalization Company Risk. Investing in securities of small
and medium capitalization companies involves greater risk than customarily is
associated with investing in larger, more established companies. These
companies' securities may be more volatile and less liquid than those of more
established companies. These securities may have returns that vary, sometimes
significantly, from the overall securities market. Often small and medium
capitalization companies and the industries in which they focus are still evolving
and, as a result, they may be more sensitive to changing market conditions.

Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater
portion of its assets in securities of individual issuers than a diversified
fund. As a result, changes in the market value of a single investment could
cause greater fluctuations in Share price than would occur in a diversified
fund. This may increase the Fund's volatility and cause the performance of a
relatively small number of issuers to have a greater impact on the Fund's
performance.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC
or any other government agency.

PowerShares Dynamic Financial Sector Portfolio (Prospectus Summary) | PowerShares Dynamic Financial Sector Portfolio

PowerShares Dynamic Financial Sector Portfolio

Investment Objective

The PowerShares Dynamic Financial Sector Portfolio (the "Fund") seeks investment
results that generally correspond (before fees and expenses) to the price and
yield of the Dynamic Financial Sector IntellidexSM Index (the "Underlying
Intellidex").

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors may pay brokerage commissions on their
purchases and sales of Shares, which are not reflected in the table or the
example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		PowerShares Dynamic Financial Sector Portfolio
Management Fees		0.50%
Other Expenses		0.79%
Acquired Fund Fees and Expenses	[1]	0.01%
Total Annual Fund Operating Expenses		1.30%
Fee Waivers and Expense Assumption	[2]	0.65%
Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption	[2]	0.65%

Example

This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. This example assumes that you invest
$10,000 in the Fund for the time periods indicated and then sell all of your
Shares at the end of those periods. The example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. The cost under the one year example is equal to the Total Annual
Fund Operating Expenses After Fee Waivers and Expense Assumption in the first year
and the Total Annual Fund Operating Expenses thereafter. This example does not
include the brokerage commissions that investors may pay to buy and sell Shares of
the Fund.

Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Expense Example (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
PowerShares Dynamic Financial Sector Portfolio	66	348	651	1,511

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover was 59% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 80% of its total assets in common stocks
of financial services companies. The Fund generally will invest at least 90% of
its total assets in common stocks that comprise the Underlying Intellidex. As of
June 30, 2011, the Underlying Intellidex was comprised of stocks of 60 U.S.
financial services companies. These companies are principally engaged in the
business of providing services and products, including banking, investment
services, insurance and real estate finance services. Strictly in accordance
with its existing guidelines and mandated procedures, NYSE Arca, Inc. ("NYSE
Arca" or the "Intellidex Provider") includes stocks principally on the basis of
their capital appreciation potential that it identifies pursuant to a
proprietary Intellidex methodology. As of June 30, 2011, the Underlying
Intellidex included common stocks of companies with a market capitalization
range of between $310 million and $31 billion.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying
Intellidex reflects a concentration in that industry or group of industries. The
Fund will not otherwise concentrate its investments in securities of issuers in
any one industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Financial Services Sector Risk. The Fund may be susceptible to adverse economic
or regulatory occurrences affecting the financial services sector. Investing in
the financial services sector involves risks, including the following: financial
services companies are subject to extensive government regulation and, as a
result, their profitability may be affected by new regulations or regulatory
interpretations; unstable interest rates can have a disproportionate effect on
the financial services sector; financial services companies whose securities the
Fund may purchase may themselves have concentrated portfolios, which makes them
vulnerable to economic conditions that affect that sector; and financial
services companies have been affected by increased competition, which could
adversely affect the profitability or viability of such companies.

Market Risk. Securities in the Underlying Intellidex are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Intellidex.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets and disruption in the creation/redemption process of the Fund.
Any of these factors may lead to the Shares trading at a premium or discount to
the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or debt
instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Intellidex is
comprised of issuers in a single industry or sector of the economy. By focusing
in an industry or sector, the Fund faces more risks than if it were diversified
broadly over numerous industries and sectors of the economy. At times, such
industry or group of industries may be out of favor and underperform other
industries or the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Intellidex for a number of reasons. For example, the Fund incurs
operating expenses not applicable to the Underlying Intellidex, and incurs costs
in buying and selling securities, especially when rebalancing the Fund's
securities holdings to reflect changes in the composition of the Underlying
Intellidex. In addition, the performance of the Fund and the Underlying
Intellidex may vary due to asset valuation differences and differences between
the Fund's portfolio and the Underlying Intellidex resulting from legal
restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Intellidex.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Intellidex, even if that
security generally is underperforming.

Small and Medium Capitalization Company Risk. Investing in securities of small
and medium capitalization companies involves greater risk than customarily is
associated with investing in larger, more established companies. These
companies' securities may be more volatile and less liquid than those of more
established companies. These securities may have returns that vary, sometimes
significantly, from the overall securities market. Often small and medium
capitalization companies and the industries in which they focus are still
evolving and, as a result, they may be more sensitive to changing market
conditions.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC
or any other government agency.

Performance

The bar chart below shows how the Fund has performed. The table below the bar
chart shows the Fund's average annual total returns (before and after taxes).
The bar chart and table provide an indication of the risks of investing in the
Fund by showing how the Fund's total return has varied from year to year and by
showing how the Fund's average annual total returns compared with a broad
measure of market performance. The Fund's performance reflects fee waivers, if
any, absent which, performance would have been lower. Although the information
shown in the bar chart and the table gives you some idea of the risks involved
in investing in the Fund, the Fund's past performance (before and after taxes)
is not necessarily indicative of how the Fund will perform in the future.
Updated performance information is available online at

The bar chart below shows how the Fund has performed.

Annual Total Returns-Calendar Year

The Fund's year-to-date total return for the six months ended June 30, 2011 was
3.46%.

After-tax returns in the table below are calculated using the historical highest
individual federal marginal income tax rates and do not reflect the impact of
state and local taxes. Actual after-tax returns depend on an investor's tax
situation and may differ from those shown, and after-tax returns shown are not
relevant to investors who hold Shares through tax-deferred arrangements, such as
401(k) plans or individual retirement accounts. In the event of negative
performance displayed in the table below, the Fund's returns after taxes on
distributions and sale of Fund Shares are calculated assuming that an investor
has sufficient capital gains of the same character from other investments to
offset any capital losses from the sale of Fund Shares so that the investor may
deduct the losses in full. As a result, the Fund's returns after taxes on
distributions and sale of Fund Shares may exceed the Fund's returns before taxes
and/or returns after taxes on distributions.

[1] Acquired Fund Fees and Expenses are indirect fees and expenses that the Fund incurs from investing in the shares of other investment companies. Please note that the amount of Total Annual Fund Operating Expenses shown in the above table may differ from the ratio of expenses prior to waivers and/or recapture to average net assets included in the "Financial Highlights" section of this Prospectus, which reflects the operating expenses of the Fund and does not include indirect expenses such as Acquired Fund Fees and Expenses.

[2] Invesco PowerShares Capital Management LLC (the "Adviser") has agreed to waive fees and/or pay Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, brokerage commissions and other trading expenses, sub-licensing fees, offering costs, taxes and extraordinary expenses) from exceeding 0.60% of the Fund's average daily net assets per year (the "Expense Cap") until at least August 31, 2012, and neither the Adviser nor the Fund can discontinue the agreement prior to its expiration. The expenses borne by the Adviser are subject to recapture by the Adviser for up to three years from the date the fee or expense was borne by the Adviser, but no recapture payment will be made by the Fund if it would result in the Fund exceeding its Expense Cap.

Investment Strategy, Heading	rr_StrategyHeading	Principal Investment Strategies
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 90% of its total assets in the component securities that compose the Underlying Index. The Underlying Index is comprised of common stocks of "large value" U.S. companies (including real estate investment trusts ("REITs")) that Research Affiliates, LLC ("RAFI Affiliates" or the "Index Provider") classifies based on its Fundamental Index® methodology. Strictly in accordance with its existing guidelines and mandated procedures, the Index Provider identifies the common stocks for inclusion in the Underlying Index from a universe of the 2,500 largest U.S. companies. The use of the word "Fundamental" in the Fund's name reflects the fact that, in identifying the common stocks, the Index Provider uses fundamental measures of company size, rather than market capitalization (company share price multiplied by number of shares outstanding). The Index Provider uses the following fundamental measures to include common stocks in the Underlying Index: book value, income, sales and dividends. The Index Provider calculates a composite fundamental weight for each common stock by equally weighting the above four fundamental measures. The Index Provider ranks each common stock by its fundamental weight and, based on this ranking, divides common stocks into three size groups: "large," "mid" and "small." The common stocks it ranks in the top 70% of the eligible universe by fundamental weight comprise the "large" size group, the next 20% comprise the "mid" size group, and the final 10% comprise the "small" size group. The Index Provider divides the "large" size group further into "growth," "core" or "value" subsets based on the Fundamental Index® methodology style score, which uses a combination of fundamental growth rates and fundamental valuation ratios. The Underlying Index is composed only of those common stocks that the Index Provider classifies as both "large" and "value." The Fund generally will invest at least 80% of its total assets in common stocks of "fundamentally large" companies. The Fund considers "fundamentally large" companies to be those companies that comprise the Underlying Index. The use of the word "Pure" in the Fund's name reflects that, in selecting securities for the Underlying Index, the Index Provider includes only those securities that it has classified as "value." Although "value" funds also could include some stocks that, based on their classification, would be considered "growth" or "core," the Underlying Index contains only those stocks that the Index Provider classifies as pure "value" stocks. The Fund generally will invest in all of the securities comprising its Underlying Index in proportion to their weightings in the Underlying Index. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its net assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Investment Strategy, Portfolio Concentration	rr_StrategyPortfolioConcentration	The Fund will concentrate its investments (i.e., invest 25% or more of the value of its net assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. "Fundamentally Large" Company Risk. Returns on investments in common stocks of "fundamentally large" U.S. companies could trail the returns on investments in common stocks of smaller companies or other large companies based on market capitalization. REIT Risk. Although the Fund will not invest in real estate directly, the REITs in which the Fund invests are subject to risks inherent in the direct ownership of real estate. These risks include, but are not limited to, a possible lack of mortgage funds and associated interest rate risks, overbuilding, property vacancies, increases in property taxes and operating expenses, changes in zoning laws, losses due to environmental damages and changes in neighborhood values and appeal to purchasers. Value Risk. "Value" securities are subject to the risk that the valuations never improve or that the returns on "value" securities are less than returns on other styles of investing or the overall stock market. Thus, the value of the Fund's investments will vary and at times may be lower or higher than that of other types of investments. Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Index may be comprised of issuers in a single industry or sector of the economy. If the Fund is focused in an industry or sector, it may present more risks than if it were broadly diversified over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries of the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Index resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming. Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund's volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund's performance. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Investment Strategy, Heading	rr_StrategyHeading	Principal Investment Strategies
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 80% of its total assets in common stocks of companies engaged in energy exploration and production. The Fund generally will invest at least 90% of its total assets in common stocks that comprise the Underlying Intellidex. As of June 30, 2011, the Underlying Intellidex was composed of stocks of 30 U.S. companies involved in the exploration and production of natural resources used to produce energy. These companies are engaged principally in exploration, extraction and production of crude oil and natural gas from land-based or offshore wells. These companies include petroleum refineries that process the crude oil into finished products, such as gasoline and automotive lubricants, and companies involved in gathering and processing natural gas, and manufacturing natural gas liquid. Strictly in accordance with its existing guidelines and mandated procedures, the Intellidex Provider includes stocks principally on the basis of their capital appreciation potential that it identifies pursuant to a proprietary Intellidex methodology. As of June 30, 2011, the Underlying Intellidex included common stocks of companies with a market capitalization range of between approximately $343 million and $396 billion. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Intellidex reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.

The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. Energy Exploration and Production Industry Concentration Risk. Companies in the energy exploration and production industry are subject to extensive government regulation, which may increase the cost of business and limit these companies' earnings. In addition, these companies are at risk of civil liability from accidents resulting in injury or loss of life or property, pollution or other environmental damage claims and risk of loss from terrorism and natural disasters. Companies in this industry could be adversely affected by levels and volatility of global energy prices, commodity price volatility, changes in exchange rates and interest rates, imposition of import controls, increased competition, capital expenditures on exploration and production, depletion of resources, development of alternative energy sources and energy conservation efforts, technological developments and labor relations. Market Risk. Securities in the Underlying Intellidex are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Intellidex. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Intellidex is comprised of issuers in a single industry or sector of the economy. By focusing in an industry or sector, the Fund faces more risks than if it were diversified broadly over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries or the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Intellidex for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Intellidex, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Intellidex. In addition, the performance of the Fund and the Underlying Intellidex may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Intellidex resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Intellidex. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Intellidex, even if that security generally is underperforming. Small and Medium Capitalization Company Risk. Investing in securities of small and medium capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Often small and medium capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund's volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund's performance. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective.

PowerShares FTSE RAFI U.S. 1000 Portfolio (Prospectus Summary) | PowerShares FTSE RAFI U.S. 1000 Portfolio

PowerShares FTSE RAFI US 1000 Portfolio

Investment Objective

The PowerShares FTSE RAFI US 1000 Portfolio (the "Fund") seeks investment
results that generally correspond (before fees and expenses) to the price and
yield of the FTSE RAFI US 1000 Index (the "Underlying Index").

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors may pay brokerage commissions on their
purchases and sales of Shares, which are not reflected in the table or the
example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		PowerShares FTSE RAFI U.S. 1000 Portfolio
Management Fees		0.29%
Other Expenses		0.15%
Total Annual Fund Operating Expenses		0.44%
Fee Waivers and Expense Assumption	[1]	0.05%
Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption	[1]	0.39%

Example

This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. This example assumes that you invest
$10,000 in the Fund for the time periods indicated and then sell all of your
Shares at the end of those periods. The example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. The cost under the one year example is equal to the Total
Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the
first year and the Total Annual Fund Operating Expenses thereafter. This example
does not include the brokerage commissions that investors may pay to buy and
sell Shares of the Fund.

Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Expense Example (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
PowerShares FTSE RAFI U.S. 1000 Portfolio	40	136	241	550

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover rate was 9% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 90% of its total assets in common stocks
that comprise the Underlying Index. As of June 30, 2011, the Underlying Index
was composed of approximately 1,000 U.S. stocks. The Underlying Index is
designed to track the performance of the largest U.S. equity stocks that FTSE
International Limited and Research Affiliates LLC ("FTSE" and "RA" or the "Index
Provider"), strictly in accordance with its existing guidelines and mandated
procedures, includes based on the following four fundamental measures: book
value, income, sales and dividends. As of June 30, 2011, the Underlying Index
included common stocks of companies with a market capitalization range of
between approximately $53 million and $403 billion.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying Index
reflects a concentration in that industry or group of industries. The Fund will
not otherwise concentrate its investments in securities of issuers in any one
industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Market Risk. Securities in the Underlying Index are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Index.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for Shares, losses from trading in secondary
markets, and disruption in the creation/redemption process of the Fund. Any of
these factors may lead to Shares trading at a premium or discount to the Fund's
net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
of an issuer may be particularly sensitive to general movements in the stock market;
or a drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock of an
issuer in the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a company's
capital structure, in terms of priority to corporate income, and therefore will be
subject to greater dividend risk than preferred stocks or debt instruments of
such issuers.

Concentration Risk. A significant percentage of the Underlying Index may be
composed of issuers in a single industry or sector of the economy. If the Fund
is focused in an industry or sector, it may present more risks than if it were
broadly diversified over numerous industries and sectors of the economy. At
times, such industry or group of industries may be out of favor and underperform
other industries of the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Index for a number of reasons. For example, the Fund incurs operating
expenses not applicable to the Underlying Index, and incurs costs in buying and
selling securities, especially when rebalancing the Fund's securities holdings
to reflect changes in the composition of the Underlying Index. In addition, the
performance of the Fund and the Underlying Index may vary due to asset valuation
differences and differences between the Fund's portfolio and the Underlying
Index resulting from legal restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Index.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Index, even if that
security generally is underperforming.

Small and Medium Capitalization Company Risk. Investing in securities of small
and medium capitalization companies involves greater risk than customarily is
associated with investing in larger, more established companies. These
companies' securities may be more volatile and less liquid than those of more
established companies. These securities may have returns that vary, sometimes
significantly, from the overall securities market. Often small and medium
capitalization companies and the industries in which they focus are still
evolving and, as a result, they may be more sensitive to changing market
conditions.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC
or any other government agency.

PowerShares Dynamic Biotechnology & Genome Portfolio	64	206	360	809

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover rate was 81% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 80% of its total assets in common stocks
of biotechnology companies and genome companies. The Fund generally will invest
at least 90% of its total assets in common stocks that comprise the Underlying
Intellidex. As of June 30, 2011, the Underlying Intellidex was composed of
stocks of 30 U.S. biotechnology and genome companies. These companies are
engaged principally in the research, development, manufacture and marketing and
distribution of various biotechnological products, services and processes and
companies that benefit significantly from scientific and technological advances
in biotechnology and genetic engineering and research. These companies may
include, for example, companies involved in the research, development or
production of pharmaceuticals, including veterinary drugs. Strictly in
accordance with its existing guidelines and mandated procedures, the Intellidex
Provider includes stocks principally on the basis of their capital appreciation
potential that it identifies pursuant to a proprietary Intellidex methodology.
As of June 30, 2011, the Underlying Intellidex included common stocks of
companies with a market capitalization range of between approximately $173
million and $54 billion.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying
Intellidex reflects a concentration in that industry or group of industries. The
Fund will not otherwise concentrate its investments in securities of issuers in
any one industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Biotechnology/Genome Industry Concentration Risk. The biotechnology and genome
industry can be significantly affected by patent considerations, including the
termination of patent protections for their products, intense competition both
domestically and internationally, rapid technological change and obsolescence,
government regulation and expensive insurance costs due to the risk of product
liability lawsuits. In addition, the biotechnology and genome industry is an
emerging growth industry, and therefore biotechnology and genome companies may
be thinly capitalized and more volatile than companies with greater
capitalizations. Biotechnology and genome companies must contend with high
development costs, which may be exacerbated by the inability to raise prices
to cover costs because of managed care pressure, government regulation or price
controls.

Market Risk. Securities in the Underlying Intellidex are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Intellidex.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets, and disruption in the creation/redemption process of the
Fund. Any of these factors may lead to the Shares trading at a premium or
discount to the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or debt
instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Intellidex is
comprised of issuers in a single industry or sector of the economy. By focusing
in an industry or sector, the Fund faces more risks than if it were diversified
broadly over numerous industries and sectors of the economy. At times, such
industry or group of industries may be out of favor and underperform other
industries or the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Intellidex for a number of reasons. For example, the Fund incurs
operating expenses not applicable to the Underlying Intellidex, and incurs costs
in buying and selling securities, especially when rebalancing the Fund's
securities holdings to reflect changes in the composition of the Underlying
Intellidex. In addition, the performance of the Fund and the Underlying
Intellidex may vary due to asset valuation differences and differences between
the Fund's portfolio and the Underlying Intellidex resulting from legal
restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Intellidex.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Intellidex, even if that
security generally is underperforming.

Small and Medium Capitalization Company Risk. Investing in securities of small
and medium capitalization companies involves greater risk than customarily is
associated with investing in larger, more established companies. These
companies' securities may be more volatile and less liquid than those of more
established companies. These securities may have returns that vary, sometimes
significantly, from the overall securities market. Often small and medium
capitalization companies and the industries in which they focus are still evolving
and, as a result, they may be more sensitive to changing market conditions.

Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater
portion of its assets in securities of individual issuers than a diversified
fund. As a result, changes in the market value of a single investment could
cause greater fluctuations in Share price than would occur in a diversified
fund. This may increase the Fund's volatility and cause the performance of a
relatively small number of issuers to have a greater impact on the Fund's
performance.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC
or any other government agency.

[1] Invesco PowerShares Capital Management LLC (the" Adviser") has agreed to waive fees and/or pay Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, brokerage commissions and other trading expenses, sub-licensing fees, offering costs, taxes and extraordinary expenses) from exceeding 0.60% of the Fund's average daily net assets per year (the "Expense Cap") until at least August 31, 2012, and neither the Adviser nor the Fund can discontinue the agreement prior to its expiration. The expenses borne by the Adviser are subject to recapture by the Adviser for up to three years from the date the fee or expense was borne by the Adviser, but no recapture payment will be made by the Fund if it would result in the Fund exceeding its Expense Cap.

PowerShares Dynamic Building & Construction Portfolio (Prospectus Summary) | PowerShares Dynamic Building & Construction Portfolio

PowerShares Dynamic Building & Construction Portfolio

Investment Objective

The PowerShares Dynamic Building & Construction Portfolio (the "Fund") seeks
investment results that generally correspond (before fees and expenses) to the
price and yield of the Dynamic Building & Construction IntellidexSM Index (the
"Underlying Intellidex").

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors may pay brokerage commissions on their
purchases and sales of Shares, which are not reflected in the table or the
example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		PowerShares Dynamic Building & Construction Portfolio
Management Fees		0.50%
Other Expenses		0.41%
Total Annual Fund Operating Expenses		0.91%
Fee Waivers and Expense Assumption	[1]	0.28%
Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption	[1]	0.63%

Example

This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. This example assumes that you invest
$10,000 in the Fund for the time periods indicated and then sell all of your
Shares at the end of those periods. The example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. The cost under the one year example is equal to the Total
Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the
first year and the Total Annual Fund Operating Expenses thereafter. This example
does not include the brokerage commissions that investors may pay to buy and
sell Shares of the Fund.

Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Expense Example (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
PowerShares Dynamic Building & Construction Portfolio	64	262	476	1,094

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover rate was 75% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 80% of its total assets in common stocks
of building and construction companies. The Fund generally will invest at least
90% of its total assets in common stocks that comprise the Underlying
Intellidex. As of June 30, 2011, the Underlying Intellidex was composed of
stocks of 30 U.S. building and construction companies. These companies are
engaged primarily in providing construction and related engineering services for
building and remodeling residential properties, commercial or industrial
buildings, or working on large-scale infrastructure projects, such as highways,
tunnels, bridges, dams, power lines and airports. These companies also may
include manufacturers of building materials for home improvement and general
construction projects and specialized machinery used for building and
construction; companies that provide installation/maintenance/repair work; and
land developers. Strictly in accordance with its existing guidelines and
mandated procedures, the Intellidex Provider includes stocks principally on the
basis of their capital appreciation potential that it identifies pursuant to a
proprietary Intellidex methodology. As of June 30, 2011, the Underlying
Intellidex included common stocks of companies with a market capitalization
range of between approximately $190 million and $56 billion.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying
Intellidex reflects a concentration in that industry or group of industries. The
Fund will not otherwise concentrate its investments in securities of issuers in
any one industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Building and Construction Industry Concentration Risk. Companies in the building
and construction industry are affected by supply and demand both for their
specific products or services and for industrial sector products in general. The
building and construction industry also may be significantly affected by changes
in government spending, zoning laws, economic conditions, interest rates,
taxation, real estate values and overbuilding. The products of companies that
operate in the building and construction industry may face obsolescence due to
rapid technological developments and frequent new product introduction. In
addition, government regulation, world events and economic conditions affect the
performance of companies in these industries.

Market Risk. Securities in the Underlying Intellidex are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Intellidex.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets, and disruption in the creation/redemption process of the
Fund. Any of these factors may lead to the Shares trading at a premium or
discount to the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or debt
instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Intellidex is
comprised of issuers in a single industry or sector of the economy. By focusing
in an industry or sector, the Fund faces more risks than if it were diversified
broadly over numerous industries and sectors of the economy. At times, such
industry or group of industries may be out of favor and underperform other
industries or the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Intellidex for a number of reasons. For example, the Fund incurs
operating expenses not applicable to the Underlying Intellidex, and incurs costs
in buying and selling securities, especially when rebalancing the Fund's
securities holdings to reflect changes in the composition of the Underlying
Intellidex. In addition, the performance of the Fund and the Underlying
Intellidex may vary due to asset valuation differences and differences between
the Fund's portfolio and the Underlying Intellidex resulting from legal
restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Intellidex.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Intellidex, even if that
security generally is underperforming.

Small and Medium Capitalization Company Risk. Investing in securities of small
and medium capitalization companies involves greater risk than customarily is
associated with investing in larger, more established companies. These
companies' securities may be more volatile and less liquid than those of more
established companies. These securities may have returns that vary, sometimes
significantly, from the overall securities market. Often small and medium
capitalization companies and the industries in which they focus are still evolving
and, as a result, they may be more sensitive to changing market conditions.

Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater
portion of its assets in securities of individual issuers than a diversified
fund. As a result, changes in the market value of a single investment could
cause greater fluctuations in Share price than would occur in a diversified
fund. This may increase the Fund's volatility and cause the performance of a
relatively small number of issuers to have a greater impact on the Fund's
performance.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC
or any other government agency.

Performance

The bar chart below shows how the Fund has performed. The table below the bar
chart shows the Fund's average annual total returns (before and after taxes).
The bar chart and table provide an indication of the risks of investing in the
Fund by showing how the Fund's total return has varied from year to year and by
showing how the Fund's average annual total returns compared with a broad
measure of market performance. The Fund's performance reflects fee waivers, if
any, absent which, performance would have been lower. Although the information
shown in the bar chart and the table gives you some idea of the risks involved
in investing in the Fund, the Fund's past performance (before and after taxes)
is not necessarily indicative of how the Fund will perform in the future.
Updated performance information is available online at
www.InvescoPowerShares.com.

The bar chart below shows how the Fund has performed.

Annual Total Returns-Calendar Years

The Fund's year-to-date total return for the six months ended June 30, 2011 was
2.33%.

        Best Quarter                    Worst Quarter
19.17% (2nd Quarter 2009)       (21.87)% (1st Quarter 2009)

After-tax returns in the table below are calculated using the historical highest
individual federal marginal income tax rates and do not reflect the impact of
state and local taxes. Actual after-tax returns depend on an investor's tax
situation and may differ from those shown, and after-tax returns shown are not
relevant to investors who hold Shares through tax-deferred arrangements, such as
401(k) plans or individual retirement accounts. In the event of negative
performance displayed in the table below, the Fund's returns after taxes on
distributions and sale of Fund Shares are calculated assuming that an investor
has sufficient capital gains of the same character from other investments to
offset any capital losses from the sale of Fund Shares so that the investor may
deduct the losses in full. As a result, the Fund's returns after taxes on
distributions and sale of Fund Shares may exceed the Fund's returns before taxes
and/or returns after taxes on distributions.

[1] Invesco PowerShares Capital Management LLC (the "Adviser") has agreed to waive fees and/or pay Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, brokerage commissions and other trading expenses, sub-licensing fees, offering costs, taxes and extraordinary expenses) from exceeding 0.60% of the Fund's average daily net assets per year (the "Expense Cap") until at least August 31, 2012, and neither the Adviser nor the Fund can discontinue the agreement prior to its expiration. The expenses borne by the Adviser are subject to recapture by the Adviser for up to three years from the date the fee or expense was borne by the Adviser, but no recapture payment will be made by the Fund if it would result in the Fund exceeding its Expense Cap.

Portfolio Turnover	rr_PortfolioTurnoverTextBlock	The Fund pays transaction costs, such as commissions, when it purchases and sells securities (or "turns over" its portfolio). A higher portfolio turnover will cause the Fund to incur additional transaction costs and may result in higher taxes when Fund Shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the example, may affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 102% of the average value of its portfolio.

Expense Example, Narrative	rr_ExpenseExampleNarrativeTextBlock	This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. This example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your Shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The cost under the one year example is equal to the Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the first year and the Total Annual Fund Operating Expenses thereafter. This example does not include the brokerage commissions that investors may pay to buy and sell Shares of the Fund.

Investment Strategy, Heading	rr_StrategyHeading	Principal Investment Strategies
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 80% of its total assets in common stocks of retail companies. The Fund generally will invest at least 90% of its total assets in common stocks that comprise the Underlying Intellidex. As of June 30, 2011, the Underlying Intellidex was composed of stocks of 30 U.S. retailers. These companies are engaged principally in operating general merchandise stores such as department stores, discount stores, warehouse clubs and superstores; specialty stores, including apparel, electronics, accessories and footwear stores; and home improvement and home furnishings stores. Dealers of motor vehicles and parts, auction houses or rental companies also may be included. Strictly in accordance with its existing guidelines and mandated procedures, the Intellidex Provider includes stocks principally on the basis of their capital appreciation potential that it identifies pursuant to a proprietary Intellidex methodology. As of June 30, 2011, the Underlying Intellidex included common stocks of companies with a market capitalization range of between approximately $372 million and $183 billion. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Intellidex reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Investment Strategy, Portfolio Concentration	rr_StrategyPortfolioConcentration	The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Intellidex reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. Retail Industry Concentration Risk. The retail industry may be affected by the performance of the domestic and international economy, interest rates, competition and consumer confidence. The success of companies in the retail industry depends heavily on disposable household income and consumer spending, and changes in demographics and consumer preferences can affect the success of retail products. The success of retail products may be strongly affected by fads, marketing campaigns and other factors affecting supply and demand. In addition, the retail industry is subject to severe competition. Market Risk. Securities in the Underlying Intellidex are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Intellidex. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Intellidex is comprised of issuers in a single industry or sector of the economy. By focusing in an industry or sector, the Fund faces more risks than if it were diversified broadly over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries or the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Intellidex for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Intellidex, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Intellidex. In addition, the performance of the Fund and the Underlying Intellidex may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Intellidex resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Intellidex. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Intellidex, even if that security generally is underperforming. Small and Medium Capitalization Company Risk. Investing in securities of small and medium capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Often small and medium capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund's volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund's performance. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC or any other government agency.
Risk, Lose Money	rr_RiskLoseMoney	The Shares will change in value, and you could lose money by investing in the Fund.
Risk, Nondiversified Status	rr_RiskNondiversifiedStatus	The Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund's volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund's performance.

Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 80% of its total assets in common stocks of energy companies. The Fund generally will invest at least 90% of its total assets in common stocks that comprise the Underlying Intellidex. As of June 30, 2011, the Underlying Intellidex was comprised of stocks of 60 U.S. energy companies. These companies are principally engaged in the business of producing, distributing or servicing energy-related products, including oil and gas exploration and production, refining, oil services, pipeline, and solar, wind and other non-oil based energy. Strictly in accordance with its existing guidelines and mandated procedures, NYSE Arca, Inc. ("NYSE Arca" or the "Intellidex Provider") includes stocks principally on the basis of their capital appreciation potential that it identifies pursuant to a proprietary Intellidex methodology. As of June 30, 2011, the Underlying Intellidex included common stocks of companies with a market capitalization range of between $343 million and $400 billion. Concentration Policy.

Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. Energy Sector Risk. Changes in worldwide energy prices, exploration and production spending may adversely affect companies in the energy sector. Changes in government regulation, world events and economic conditions also affect these companies. In addition, these companies are at risk of civil liability from accidents resulting in injury, loss of life or property, pollution or other environmental damage claims and risk of loss from terrorism and natural disasters. Commodity price volatility, changes in exchange rates, imposition of import controls, increased competition, depletion of resources, development of alternative energy sources, technological developments and labor relations also could affect companies in this sector. Oil and Gas Services Industry Risk. The profitability of companies in the oil and gas services industry may be affected adversely by world events in the regions that the companies operate (e.g., expropriation, nationalization, confiscation of assets and property or the imposition of restrictions on foreign investments and repatriation of capital, military coups, social unrest, violence or labor unrest). Companies in the oil and gas services industry may have significant capital investments in, or engage in transactions involving, emerging market countries, which may heighten these risks. Market Risk. Securities in the Underlying Intellidex are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Intellidex. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Intellidex is comprised of issuers in a single industry or sector of the economy. By focusing in an industry or sector, the Fund faces more risks than if it were diversified broadly over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries or the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Intellidex for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Intellidex, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Intellidex. In addition, the performance of the Fund and the Underlying Intellidex may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Intellidex resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Intellidex. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Intellidex, even if that security generally is underperforming. Small and Medium Capitalization Company Risk. Investing in securities of small and medium capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Often small and medium capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC or any other government agency.

A higher portfolio turnover will cause the Fund to incur additional transaction costs and may result in higher taxes when Fund Shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the example, may affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 46% of the average value of its portfolio.

This example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your Shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The cost under the one year example is equal to the Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the first year and the Total Annual Fund Operating Expenses thereafter. This example does not include the brokerage commissions that investors may pay to buy and sell Shares of the Fund.

Investment Strategy, Heading	rr_StrategyHeading	Principal Investment Strategies
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 80% of its total assets in common stocks of software companies. The Fund generally will invest at least 90% of its total assets in common stocks that comprise the Underlying Intellidex. As of June 30, 2011, the Underlying Intellidex was composed of stocks of 30 U.S. software companies. These companies are engaged principally in the research, design, production or distribution of products or processes that relate to software applications and systems and information-based services. These companies may include, for example, companies that design products such as systems-level software (to run the basic functions of a computer) or applications software (for one type of work) for general use or use by certain industries or groups; companies that provide communications software; and companies that provide time-sharing services, internet software and home entertainment software. Strictly in accordance with its existing guidelines and mandated procedures, the Intellidex Provider includes stocks principally on the basis of their capital appreciation potential that it identifies pursuant to a proprietary Intellidex methodology. As of June 30, 2011, the Underlying Intellidex included common stocks of companies with a market capitalization range of between approximately $474 million and $173 billion. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Intellidex reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Investment Strategy, Portfolio Concentration	rr_StrategyPortfolioConcentration	The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Intellidex reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. Software Industry Concentration Risk. Technological developments, fixed-rate pricing and the ability to attract and retain skilled employees, can significantly affect the software industry. The success of companies in the industry is also subject to the continued demand for internet services. Market Risk. Securities in the Underlying Intellidex are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Intellidex. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Intellidex is comprised of issuers in a single industry or sector of the economy. By focusing in an industry or sector, the Fund faces more risks than if it were diversified broadly over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries or the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Intellidex for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Intellidex, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Intellidex. In addition, the performance of the Fund and the Underlying Intellidex may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Intellidex resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Intellidex. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Intellidex, even if that security generally is underperforming. Small and Medium Capitalization Company Risk. Investing in securities of small and medium capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Often small and medium capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund's volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund's performance. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC or any other government agency.

The PowerShares WilderHill Progressive Energy Portfolio (the "Fund") seeks
investment results that generally correspond (before fees and expenses) to the
price and yield of the WilderHill Progressive Energy Index (the "Underlying
Index").

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors may pay brokerage commissions on their
purchases and sales of Shares, which are not reflected in the table or the
example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		PowerShares WilderHill Progressive Energy Portfolio
Management Fees		0.50%
Other Expenses		0.36%
Total Annual Fund Operating Expenses		0.86%
Fee Waivers and Expense Assumption	[1]	0.16%
Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption	[1]	0.70%

Example

This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. This example assumes that you invest
$10,000 in the Fund for the time periods indicated and then sell all of your
Shares at the end of those periods. The example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. The cost under the one year example is equal to the Total
Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the
first year and the Total Annual Fund Operating Expenses thereafter. This example
does not include the brokerage commissions that investors may pay to buy and
sell Shares of the Fund.

Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Expense Example (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
PowerShares WilderHill Progressive Energy Portfolio	72	258	461	1,046

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover was 22% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 80% of its total assets in common stocks
of companies engaged principally in the progressive energy business. The Fund
generally will invest at least 90% of its total assets in common stocks that
comprise the Underlying Index. Strictly in accordance with its existing
guidelines and mandated procedures, Progressive Energy Index LLC ("Progressive
Index" or the "Index Provider") includes the companies in the Underlying Index
pursuant to a proprietary selection methodology. As of the date of this
Prospectus, the Underlying Index was composed of common stocks of approximately
52 companies that are publicly traded in the United States and engaged in a
business or businesses, which the Underlying Index Selection Committee believes
may substantially benefit from a societal shift toward the transitional energy
technologies significant in improving the use of fossil fuels and nuclear power.
As of the date of this Prospectus, the Underlying Index included common stocks
of companies with a market capitalization range of between approximately $150
million and $89.6 billion. The Underlying Index's Selection Committee includes
stocks based on expert evaluation. The list of component stocks is reviewed
quarterly, or more often, at the discretion of the Selection Committee.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying Index
reflects a concentration in that industry or group of industries. The Fund will
not otherwise concentrate its investments in securities of issuers in any one
industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Energy Sector Risk. Changes in worldwide energy prices, exploration and
production spending can significantly affect companies in the energy sector. In
addition, changes in government regulation, world events and economic conditions
can affect these companies. In addition, these companies are at risk of civil
liability from accidents resulting in injury, loss of life or property,
pollution or other environmental damage claims and risk of loss from terrorism
and natural disasters. Companies in this sector could be affected adversely by
commodity price volatility, changes in exchange rates, imposition of import
controls, increased competition, depletion of resources, development of
alternative energy sources, technological developments and labor relations.

Market Risk. Securities in the Underlying Index are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Index.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets, and disruption in the creation/redemption process of the
Fund. Any of these factors may lead to the Shares trading at a premium or
discount to the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or debt
instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Index is
comprised of issuers in a single industry or sector of the economy. By focusing
in an industry or sector, the Fund faces more risks than if it were diversified
broadly over numerous industries and sectors of the economy. At times, such
industry or group of industries may be out of favor and underperform other
industries or the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Index for a number of reasons. For example, the Fund incurs operating
expenses not applicable to the Underlying Index, and incurs costs in buying and
selling securities, especially when rebalancing the Fund's securities holdings
to reflect changes in the composition of the Underlying Index. In addition, the
performance of the Fund and the Underlying Index may vary due to asset valuation
differences and differences between the Fund's portfolio and the Underlying
Index resulting from legal restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Index.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Index, even if that
security generally is underperforming.

Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater
portion of its assets in securities of individual issuers than a diversified
fund. As a result, changes in the market value of a single investment could
cause greater fluctuations in Share price than would occur in a diversified
fund. This may increase the Fund's volatility and cause the performance of a
relatively small number of issuers to have a greater impact on the Fund's
performance.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC
or any other government agency.

The expenses borne by the Adviser are subject to recapture by the Adviser for up to three years from the date the fee or expense was borne by the Adviser, but no recapture payment will be made by the Fund if it would result in the Fund exceeding its Expense Cap.

results that generally correspond (before fees and expenses) to the price and
yield of the Dynamic Insurance IntellidexSM Index (the "Underlying Intellidex").

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors may pay brokerage commissions on their
purchases and sales of Shares, which are not reflected in the table or the
example below.

with the cost of investing in other funds. This example assumes that you invest
$10,000 in the Fund for the time periods indicated and then sell all of your
Shares at the end of those periods. The example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. The cost under the one year example is equal to the Total
Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover rate was 66% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 80% of its total assets in common stocks
of insurance companies. The Fund generally will invest at least 90% of its total
assets in common stocks that comprise the Underlying Intellidex. As of June 30,
2011, the Underlying Intellidex was composed of stocks of 30 U.S. insurance
companies. These companies are engaged principally in underwriting or
distributing and reselling life, health and property/casualty insurance
policies. The Underlying Intellidex may include companies that provide coverage
for various types of property and casualty risks; guarantee payment to a
beneficiary when an insured person ceases to generate income, typically at death
or retirement; or protect against financial loss resulting from medical bills
and/or the financial consequences of poor health. The Underlying Intellidex also
may include Insurance brokerage and reinsurance companies. Strictly in
accordance with its existing guidelines and mandated procedures, the Intellidex
Provider includes stocks principally on the basis of their capital appreciation
potential that it identifies pursuant to a proprietary Intellidex methodology.
As of June 30, 2011, the Underlying Intellidex included common stocks of
companies with a market capitalization range of between approximately $499
million and $31 billion.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying
Intellidex reflects a concentration in that industry or group of industries. The
Fund will not otherwise concentrate its investments in securities of issuers in
any one industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Insurance Industry Concentration Risk. Many factors, including changes in
interest rates, general economic conditions, the imposition of premium rate
caps, competition and pressure to compete globally, including price and
marketing competition, and other changes in government regulation or tax law,
can significantly affect companies in the insurance industry. In addition,
different segments of the insurance industry can be significantly affected by
mortality and morbidity rates, actuarial miscalculations, environmental clean-up
costs and catastrophic events such as earthquakes, hurricanes and terrorist
acts, and availability and cost of reinsurance.

Market Risk. Securities in the Underlying Intellidex are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Intellidex.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets, and disruption in the creation/redemption process of the
Fund. Any of these factors may lead to the Shares trading at a premium or
discount to the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or debt
instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Intellidex is
comprised of issuers in a single industry or sector of the economy. By focusing
in an industry or sector, the Fund faces more risks than if it were diversified
broadly over numerous industries and sectors of the economy. At times, such
industry or group of industries may be out of favor and underperform other
industries or the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Intellidex for a number of reasons. For example, the Fund incurs
operating expenses not applicable to the Underlying Intellidex, and incurs costs
in buying and selling securities, especially when rebalancing the Fund's
securities holdings to reflect changes in the composition of the Underlying
Intellidex. In addition, the performance of the Fund and the Underlying
Intellidex may vary due to asset valuation differences and differences between
the Fund's portfolio and the Underlying Intellidex resulting from legal
restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Intellidex.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Intellidex, even if that
security generally is underperforming.

Small and Medium Capitalization Company Risk. Investing in securities of small
and medium capitalization companies involves greater risk than customarily is
associated with investing in larger, more established companies. These
companies' securities may be more volatile and less liquid than those of more
established companies. These securities may have returns that vary, sometimes
significantly, from the overall securities market. Often small and medium
capitalization companies and the industries in which they focus are still
evolving and, as a result, they may be more sensitive to changing market
conditions.

Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater
portion of its assets in securities of individual issuers than a diversified
fund. As a result, changes in the market value of a single investment could cause
greater fluctuations in Share price than would occur in a diversified fund. This
may increase the Fund's volatility and cause the performance of a relatively small
number of issuers to have a greater impact on the Fund's performance.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC
or any other government agency.

Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 80% of its total assets in common stocks of biotechnology companies and genome companies. The Fund generally will invest at least 90% of its total assets in common stocks that comprise the Underlying Intellidex. As of June 30, 2011, the Underlying Intellidex was composed of stocks of 30 U.S. biotechnology and genome companies. These companies are engaged principally in the research, development, manufacture and marketing and distribution of various biotechnological products, services and processes and companies that benefit significantly from scientific and technological advances in biotechnology and genetic engineering and research. These companies may include, for example, companies involved in the research, development or production of pharmaceuticals, including veterinary drugs.

As of June 30, 2011, the Underlying Intellidex included common stocks of companies with a market capitalization range of between approximately $173 million and $54 billion. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Intellidex reflects a concentration in that industry or group of industries.

Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. Biotechnology/Genome Industry Concentration Risk. The biotechnology and genome industry can be significantly affected by patent considerations, including the termination of patent protections for their products, intense competition both domestically and internationally, rapid technological change and obsolescence, government regulation and expensive insurance costs due to the risk of product liability lawsuits. In addition, the biotechnology and genome industry is an emerging growth industry, and therefore biotechnology and genome companies may be thinly capitalized and more volatile than companies with greater capitalizations. Biotechnology and genome companies must contend with high development costs, which may be exacerbated by the inability to raise prices to cover costs because of managed care pressure, government regulation or price controls. Market Risk. Securities in the Underlying Intellidex are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Intellidex. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Intellidex is comprised of issuers in a single industry or sector of the economy. By focusing in an industry or sector, the Fund faces more risks than if it were diversified broadly over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries or the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Intellidex for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Intellidex, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Intellidex. In addition, the performance of the Fund and the Underlying Intellidex may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Intellidex resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Intellidex. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Intellidex, even if that security generally is underperforming. Small and Medium Capitalization Company Risk. Investing in securities of small and medium capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Often small and medium capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund's volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund's performance. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC or any other government agency.

Investment Strategy, Heading	rr_StrategyHeading	Principal Investment Strategies
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 80% of its total assets in common stocks of basic materials companies. The Fund generally will invest at least 90% of its total assets in common stocks that comprise the Underlying Intellidex. As of June 30, 2011, the Underlying Intellidex was comprised of stocks of 60 U.S. basic materials companies. These companies are principally engaged in the business of producing raw materials, including paper or wood products, chemicals, construction materials, and mining and metals. Strictly in accordance with its existing guidelines and mandated procedures, NYSE Arca, Inc. ("NYSE Arca" or the "Intellidex Provider") includes stocks principally on the basis of their capital appreciation potential that it identifies pursuant to a proprietary Intellidex methodology. As of June 30, 2011, the Underlying Intellidex included common stocks of companies with a market capitalization range of between $319 million and $50 billion. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Intellidex reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Investment Strategy, Portfolio Concentration	rr_StrategyPortfolioConcentration	The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Intellidex reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. Basic Materials Sector Risk. Changes in world events, political and economic conditions, energy conservation, environmental policies, commodity price volatility, changes in exchange rates, imposition of import controls, increased competition, depletion of resources and labor relations may adversely affect the companies engaged in the production and distribution of basic materials. Market Risk. Securities in the Underlying Intellidex are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Intellidex. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Intellidex is comprised of issuers in a single industry or sector of the economy. By focusing in an industry or sector, the Fund faces more risks than if it were diversified broadly over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries or the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Intellidex for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Intellidex, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Intellidex. In addition, the performance of the Fund and the Underlying Intellidex may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Intellidex resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Intellidex. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Intellidex, even if that security generally is underperforming. Small and Medium Capitalization Company Risk. Investing in securities of small and medium capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Often small and medium capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC or any other government agency.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover rate was 40% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 80% of its total assets in common stocks
of large capitalization companies. NYSE Arca, Inc. ("NYSE Arca" or the
"Intellidex Provider") considers a company to be a large capitalization company
if it falls within the Underlying Intellidex model, as described below. The Fund
generally will invest at least 90% of its total assets in common stocks that
comprise the Underlying Intellidex. As of June 30, 2011, the Underlying
Intellidex was composed of 50 large capitalization U.S. value stocks that,
strictly in accordance with its existing guidelines and mandated procedures,
NYSE Arca included principally on the basis of their capital appreciation
potential that NYSE Arca identifies pursuant to a proprietary Intellidex
methodology. As of June 30, 2011, the Underlying Intellidex included common
stocks of companies with a market capitalization range of between approximately
$12 billion and $396 billion.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying
Intellidex reflects a concentration in that industry or group of industries. The
Fund will not otherwise concentrate its investments in securities of issuers in
any one industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Value Investing Style Risk. "Value" securities are subject to the risk that the
valuations never improve or that the returns on "value" securities are less than
returns on other styles of investing or the overall stock market. Thus, the
value of the Fund's investments will vary and, at times, may be lower or higher
than that of other types of investments.

Market Risk. Securities in the Underlying Intellidex are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Intellidex.

Market Trading Risk. The Fund faces market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets, and disruption in the creation/redemption process of the Fund.
Any of these factors may lead to the Shares trading at a premium or discount to
the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or debt
instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Intellidex may be
composed of issuers in a single industry or sector of the economy. If the Fund
is focused in an industry or sector, it may present more risks than if it were
diversified broadly over numerous industries and sectors of the economy. At
times, such industry or group of industries may be out of favor and underperform
other industries or the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Intellidex for a number of reasons. For example, the Fund incurs
operating expenses not applicable to the Underlying Intellidex, and incurs costs
in buying and selling securities, especially when rebalancing the Fund's
securities holdings to reflect changes in the composition of the Underlying
Intellidex. In addition, the performance of the Fund and the Underlying
Intellidex may vary due to asset valuation differences and differences between
the Fund's portfolio and the Underlying Intellidex resulting from legal
restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Intellidex.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Intellidex, even if that
security generally is underperforming.

Large Capitalization Company Risk. Companies with large market capitalizations
may go in and out of favor based on market and economic conditions. Although
larger companies tend to be less volatile than companies with smaller market
capitalizations, returns on investments in securities of large capitalization
U.S. companies could trail the returns on investments in stocks of smaller
companies.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and can perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC
or any other government agency.

Performance

The bar chart below shows how the Fund has performed. The table below the bar
chart shows the Fund's average annual total returns (before and after taxes).
The bar chart and table provide an indication of the risks of investing in the
Fund by showing how the Fund's total return has varied from year to year and by
showing how the Fund's average annual total returns compared with a broad
measure of market performance. The Fund's performance reflects fee waivers, if
any, absent which, performance would have been lower. Although the information
shown in the bar chart and the table gives you some idea of the risks involved
in investing in the Fund, the Fund's past performance (before and after taxes)
is not necessarily indicative of how the Fund will perform in the future.

[1] Invesco PowerShares Capital Management LLC (the "Adviser") has agreed to waive fees and/or pay Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, brokerage commissions and other trading expenses, sub-licensing fees, offering costs, taxes and extraordinary expenses) from exceeding 0.60% of the Fund's average daily net assets per year (the "Expense Cap") until at least August 31, 2012, and neither the Adviser nor the Fund can discontinue the agreement prior to its expiration. The expenses borne by the Adviser are subject to recapture by the Adviser for up to three years from the date the fee or expense was borne by the Adviser, but no recapture payment will be made by the Fund if it would result in the Fund exceeding its Expense Cap.

Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming. Small and Medium Capitalization Company Risk. Investing in securities of small and medium capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Often small and medium capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole.

PowerShares Fundamental Pure Mid Growth Portfolio (Prospectus Summary) | PowerShares Fundamental Pure Mid Growth Portfolio

PowerShares Fundamental Pure Mid Growth Portfolio

Investment Objective

The PowerShares Fundamental Pure Mid Growth Portfolio (the "Fund") seeks
investment results that generally correspond (before fees and expenses) to
the price and yield of the RAFI® Fundamental Mid Growth Index (the "Underlying
Index").

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors may pay brokerage commissions on their
purchases and sales of Shares, which are not reflected in the table or the
example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		PowerShares Fundamental Pure Mid Growth Portfolio
Management Fee		0.29%
Other Expenses		0.40%
Total Annual Fund Operating Expenses		0.69%
Fee Waivers and Expense Assumption	[1]	0.06%
Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption	[1]	0.63%

Example

This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. This example assumes that you invest
$10,000 in the Fund for the time periods indicated and then sell all of your
Shares at the end of those periods. The example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. The cost under the one year example is equal to the Total
Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the
first year and the Total Annual Fund Operating Expenses thereafter. This example
does not include the brokerage commissions that investors may pay to buy and
sell Shares of the Fund.

Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Expense Example (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
PowerShares Fundamental Pure Mid Growth Portfolio	64	215	378	853

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Shares are held in a taxable account. These costs, which are
not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the fiscal year ended April 30, 2011, the
Fund's portfolio turnover rate was 49% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 90% of its total assets in the component
securities that comprise the Underlying Index. The Underlying Index is comprised
of common stocks of "mid growth" U.S. companies (including real estate
investment trusts ("REITs")) that Research Affiliates, LLC ("RAFI Affiliates" or
the "Index Provider") classifies based on its Fundamental Index® methodology.
Strictly in accordance with its existing guidelines and mandated procedures, the
Index Provider identifies the common stocks for inclusion in the Underlying
Index from a universe of the 2,500 largest U.S. companies. The use of the word
"Fundamental" in the Fund's name reflects the fact that, in identifying the
common stocks, the Index Provider uses fundamental measures of company size,
rather than market capitalization (company share price multiplied by number of
shares outstanding). The Index Provider uses the following fundamental measures
to include common stocks in the Underlying Index: book value, income, sales and
dividends. It then calculates a composite fundamental weight for each common
stock by equally weighting the above four fundamental measures. The Index
Provider then ranks each common stock by its fundamental weight and, based on
this ranking, divides the common stocks into three size groups: "large," "mid"
and "small." The common stocks it ranks in the top 70% of the eligible universe
by fundamental weight comprise the "large" size group, the next 20% comprise the
"mid" size group, and the final 10% comprise the "small" size group. The Index
Provider further divides the "mid" size group into "growth," "core" or "value"
subsets based on the Fundamental Index® methodology style score, which uses a
combination of fundamental growth rates and fundamental valuation ratios. The
Underlying Index is composed only of those common stocks that the Index Provider
classifies as both "mid" and "growth." The Fund generally will invest at least
80% of its total assets in common stocks of "fundamentally mid" companies. The
Fund considers "fundamentally mid" companies to be those companies that comprise
the Underlying Index.

The use of the word "Pure" in the Fund's name reflects that, in selecting
securities for the Underlying Index, the Index Provider includes only those
securities that it has classified as "growth." Although "growth" funds also
could include some stocks that, based on their classification, would be
considered "core" or "value," the Underlying Index contains only those stocks
that the Index Provider classifies as pure "growth" stocks. The Fund generally
will invest in all of the securities comprising its Underlying Index in
proportion to their weightings in the Underlying Index.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying Index
reflects a concentration in that industry or group of industries. The Fund will
not otherwise concentrate its investments in securities of issuers in any one
industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

"Fundamentally Mid" Company Risk. Investing in common stocks of "fundamentally
mid" companies involves greater risk than customarily is associated with
investing in larger, more established companies. These companies' common stocks
may be more volatile and less liquid than those of more established companies.
These common stocks may have returns that vary, sometimes significantly, from
the overall stock market. Often "fundamentally mid" companies and the industries
in which they focus are still evolving and, as a result, they may be more
sensitive to changing market conditions.

Growth Risk. The market values of "growth" securities may be more volatile than
other types of investments. The returns on "growth" securities may or may not
move in tandem with the returns on other styles of investing or the overall
stock market. Thus, the value of the Fund's investments will vary and at times
may be lower or higher than that of other types of investments.

REIT Risk. Although the Fund will not invest in real estate directly, the REITs
in which the Fund invests are subject to risks inherent in the direct ownership
of real estate. These risks include, but are not limited to, a possible lack of
mortgage funds and associated interest rate risks, overbuilding, property
vacancies, increases in property taxes and operating expenses, changes in zoning
laws, losses due to environmental damages and changes in neighborhood values and
appeal to purchasers.

Market Risk. Securities in the Underlying Index are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Index.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets, and disruption in the creation/redemption process of the
Fund. Any of these factors may lead to the Shares trading at a premium or
discount to the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or debt
instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Index may be
comprised of issuers in a single industry or sector of the economy. If the Fund
is focused in an industry or sector, it may present more risks than if it were
diversified broadly over numerous industries and sectors of the economy. At
times, such industry or group of industries may be out of favor and underperform
other industries or the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Index for a number of reasons. For example, the Fund incurs operating
expenses not applicable to the Underlying Index, and incurs costs in buying and
selling securities, especially when rebalancing the Fund's securities holdings
to reflect changes in the composition of the Underlying Index. In addition, the
performance of the Fund and the Underlying Index may vary due to asset valuation
differences and differences between the Fund's portfolio and the Underlying
Index resulting from legal restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Index.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Index, even if that
security generally is underperforming.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the
Federal Deposit Insurance Corporation or any other government agency.

Performance

The bar chart below shows how the Fund has performed. The table below the bar
chart shows the Fund's average annual total returns (before and after taxes).
The bar chart and table provide an indication of the risks of investing in the
Fund by showing how the Fund's total return has varied from year to year and by
showing how the Fund's average annual total returns compared with a broad
measure of market performance. The Fund's performance reflects fee waivers, if
any, absent which, performance would have been lower. Although the information
shown in the bar chart and the table gives you some idea of the risks involved
in investing in the Fund, the Fund's past performance (before and after taxes)
is not necessarily indicative of how the Fund will perform in the future.

The Fund generally will invest at least 90% of its total assets in common stocks that comprise the Underlying Index. Strictly in accordance with its existing guidelines and mandated procedures, Progressive Energy Index LLC ("Progressive Index" or the "Index Provider") includes the companies in the Underlying Index pursuant to a proprietary selection methodology. As of the date of this Prospectus, the Underlying Index was composed of common stocks of approximately 52 companies that are publicly traded in the United States and engaged in a business or businesses, which the Underlying Index Selection Committee believes may substantially benefit from a societal shift toward the transitional energy technologies significant in improving the use of fossil fuels and nuclear power. As of the date of this Prospectus, the Underlying Index included common stocks of companies with a market capitalization range of between approximately $150 million and $89.6 billion. The Underlying Index's Selection Committee includes stocks based on expert evaluation. The list of component stocks is reviewed quarterly, or more often, at the discretion of the Selection Committee. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.

Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. Energy Sector Risk. Changes in worldwide energy prices, exploration and production spending can significantly affect companies in the energy sector. In addition, changes in government regulation, world events and economic conditions can affect these companies. In addition, these companies are at risk of civil liability from accidents resulting in injury, loss of life or property, pollution or other environmental damage claims and risk of loss from terrorism and natural disasters. Companies in this sector could be affected adversely by commodity price volatility, changes in exchange rates, imposition of import controls, increased competition, depletion of resources, development of alternative energy sources, technological developments and labor relations. Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Index is comprised of issuers in a single industry or sector of the economy. By focusing in an industry or sector, the Fund faces more risks than if it were diversified broadly over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries or the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Index resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming. Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund's volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund's performance. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC or any other government agency.

During the most recent fiscal year, the Fund's portfolio turnover rate was 73% of the average value of its portfolio.

Investment Strategy, Heading	rr_StrategyHeading	Principal Investment Strategies
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 80% of its total assets in common stocks of food and beverage companies. The Fund generally will invest at least 90% of its total assets in common stocks that comprise the Underlying Intellidex. As of June 30, 2011, the Underlying Intellidex was composed of stocks of 30 U.S. food and beverage companies. These companies are engaged principally in the manufacture, sale or distribution of food and beverage products, agricultural products and products related to the development of new food technologies. These companies may include, for example, companies that sell products and services, such as meat and poultry processing and wholesale and retail distribution, and warehousing of food and food-related products, including restaurants, grocery stores, brewers, distillers and vintners; and companies that manufacture and distribute products including soft drinks, packaged food products (such as cereals, pet foods, and frozen foods), health food and dietary products. Strictly in accordance with its existing guidelines and mandated procedures, the Intellidex Provider includes stocks principally on the basis of their capital appreciation potential that it identifies pursuant to a proprietary Intellidex methodology. As of June 30, 2011, the Underlying Intellidex included common stocks of companies with a market capitalization range of between approximately $434 million and $154 billion. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Intellidex reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.

The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. Food and Beverage Industry Concentration Risk. The food and beverage industry is highly competitive and can be significantly affected by demographic and product trends, competitive pricing, food fads, marketing campaigns, environmental factors, government regulation, adverse changes in general economic conditions, evolving consumer preferences, nutritional and health-related concerns, federal, state and local food inspection and processing controls, consumer product liability claims, consumer boycotts, risks of product tampering and the availability and expense of liability insurance. Market Risk. Securities in the Underlying Intellidex are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Intellidex. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Intellidex is comprised of issuers in a single industry or sector of the economy. By focusing in an industry or sector, the Fund faces more risks than if it were diversified broadly over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries or the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Intellidex for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Intellidex, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Intellidex. In addition, the performance of the Fund and the Underlying Intellidex may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Intellidex resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Intellidex. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Intellidex, even if that security generally is underperforming. Small and Medium Capitalization Company Risk. Investing in securities of small and medium capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Often small and medium capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC or any other government agency.

PowerShares DWA Technical Leaders (TM) Portfolio (Prospectus Summary) | PowerShares DWA Technical Leaders (TM) Portfolio

PowerShares DWA Technical LeadersTM Portfolio

Investment Objective

The PowerShares DWA Technical LeadersTM Portfolio (the "Fund") seeks investment
results that generally correspond (before fees and expenses) to the price and
yield of the Dorsey Wright Technical LeadersTM Index (the "Underlying Index").

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors may pay brokerage commissions on their
purchases and sales of Shares, which are not reflected in the table or the
example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		PowerShares DWA Technical Leaders (TM) Portfolio
Management Fees		0.50%
Other Expenses		0.21%
Total Annual Fund Operating Expenses		0.71%
Fee Waivers and Expense Assumption	[1]	0.01%
Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption	[1]	0.70%

Example

This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. This example assumes that you invest
$10,000 in the Fund for the time periods indicated and then sell all of your
Shares at the end of those periods. The example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. The cost under the one year example is equal to the Total
Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the
first year and the Total Annual Fund Operating Expenses thereafter. This example
does not include the brokerage commissions that investors may pay to buy and
sell Shares of the Fund.

Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Expense Example (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
PowerShares DWA Technical Leaders (TM) Portfolio	72	226	394	882

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover was 42% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 90% of its total assets in common stocks
that comprise the Underlying Index. As of June 30, 2011, the Underlying Index
was composed of stocks of approximately 100 U.S. companies. Strictly in
accordance with its existing guidelines and mandated procedures, Dorsey Wright &
Associates ("Dorsey Wright" or the "Index Provider") includes stocks pursuant to
a proprietary selection methodology that is designed to identify companies that
demonstrate powerful relative strength characteristics. The Index Provider bases
the relative strength characteristics on each security's market performance. The
Index Provider includes companies from a broad mid-cap and large-cap universe.
As of June 30, 2011, the Underlying Index included common stocks of 100
companies with a market capitalization range of between approximately $2 billion
and $400 billion.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying Index
reflects a concentration in that industry or group of industries. The Fund will
not otherwise concentrate its investments in securities of issuers in any one
industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Market Risk. Securities in the Underlying Index are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Index.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets, and disruption in the creation/redemption process of the
Fund. Any of these factors may lead to the Shares trading at a premium or
discount to the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock
in the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or
debt instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Index may be
composed of issuers in a single industry or sector of the economy. If the Fund
is focused in an industry or sector, it may present more risks than if it were
broadly diversified over numerous industries and sectors of the economy. At
times, such industry or group of industries may be out of favor and underperform
other industries of the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Index for a number of reasons. For example, the Fund incurs operating
expenses not applicable to the Underlying Index, and incurs costs in buying and
selling securities, especially when rebalancing the Fund's securities holdings
to reflect changes in the composition of the Underlying Index. In addition, the
performance of the Fund and the Underlying Index may vary due to asset valuation
differences and differences between the Fund's portfolio and the Underlying
Index resulting from legal restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Index.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Index, even if that
security generally is underperforming.

Medium Capitalization Company Risk. Investing in securities of medium
capitalization companies involves greater risk than customarily is associated
with investing in larger, more established companies. These companies'
securities may be more volatile and less liquid than those of more established
companies. These securities may have returns that vary, sometimes significantly,
from the overall securities market. Often medium capitalization companies and
the industries in which they focus are still evolving, and, as a result, may be
more sensitive to changing market conditions.

Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater
portion of its assets in securities of individual issuers than a diversified
fund. As a result, changes in the market value of a single investment could
cause greater fluctuations in Share price than would occur in a diversified
fund. This may increase the Fund's volatility and cause the performance of a
relatively small number of issuers to have a greater impact on the Fund's
performance.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC
or any other government agency.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover was 32% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 80% of its total assets in common stocks
of companies engaged in the business of the advancement of cleaner energy and
conservation. The Fund generally will invest at least 90% of its total assets in
common stocks that comprise the Underlying Index. As of the date of this
Prospectus, the Underlying Index was composed of the stocks of approximately 56
companies that are publicly traded in the United States, which the Underlying
Index Selection Committee believes will substantially benefit from a societal
transition toward the use of cleaner energy and conservation. Strictly in
accordance with its existing guidelines and mandated procedures, the Underlying
Index's Selection Committee includes stocks based on expert evaluation. At its
discretion, the Selection Committee reviews the Underlying Index's components
stocks quarterly or more often. As of the date of this Prospectus, the
Underlying Index included common stocks of companies with a market
capitalization range of between approximately $44 million and $16 billion.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying Index
reflects a concentration in that industry or group of industries. The Fund will
not otherwise concentrate its investments in securities of issuers in any one
industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Clean Energy Industry Concentration Risk. Obsolescence of existing technology,
short product cycles, falling prices and profits, competition from new market
entrants and general economic conditions can significantly affect the clean
energy industry. Additionally, intense competition and legislation resulting in
more strict government regulations and enforcement policies and specific
expenditures for cleanup efforts can significantly affect the clean energy
industry. The clean energy industry also is subject to risks associated with
hazardous materials. Fluctuations in energy prices and supply and demand of
alternative energy fuels, energy conservation, the success of exploration
projects and tax and other government regulations significantly affect the clean
energy industry. In addition, supply and demand for specific products or
services, the supply and demand for oil and gas, the price of oil and gas,
production spending, government regulation, world events and economic conditions
can affect the industry.

Market Risk. Securities in the Underlying Index are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Index.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets, and disruption in the creation/redemption process of the
Fund. Any of these factors may lead to the Shares trading at a premium or
discount to the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or debt
instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Index is
comprised of issuers in a single industry or sector of the economy. By focusing
in an industry or sector, the Fund faces more risks than if it were diversified
broadly over numerous industries and sectors of the economy. At times, such
industry or group of industries may be out of favor and underperform other
industries or the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Index for a number of reasons. For example, the Fund incurs operating
expenses not applicable to the Underlying Index, and incurs costs in buying and
selling securities, especially when rebalancing the Fund's securities holdings
to reflect changes in the composition of the Underlying Index. In addition, the
performance of the Fund and the Underlying Index may vary due to asset valuation
differences and differences between the Fund's portfolio and the Underlying
Index resulting from legal restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Index.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Index, even if that
security generally is underperforming.

Small and Medium Capitalization Company Risk. Investing in securities of small
and medium capitalization companies involves greater risk than customarily is
associated with investing in larger, more established companies. These
companies' securities may be more volatile and less liquid than those of more
established companies. These securities may have returns that vary, sometimes
significantly, from the overall securities market. Often small and medium
capitalization companies and the industries in which they focus are still
evolving and, as a result, they may be more sensitive to changing market
conditions.

Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater
portion of its assets in securities of individual issuers than a diversified
fund. As a result, changes in the market value of a single investment could
cause greater fluctuations in Share price than would occur in a diversified
fund. This may increase the Fund's volatility and cause the performance of a
relatively small number of issuers to have a greater impact on the Fund's
performance.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC
or any other government agency.

Performance

The bar chart below shows how the Fund has performed. The table below the bar
chart shows the Fund's average annual total returns (before and after taxes).
The bar chart and table provide an indication of the risks of investing in the
Fund by showing how the Fund's total return has varied from year to year and by
showing how the Fund's average annual total returns compared with a broad
measure of market performance. The Fund's performance reflects fee waivers, if
any, absent which, performance would have been lower. Although the information
shown in the bar chart and the table gives you some idea of the risks involved
in investing in the Fund, the Fund's past performance (before and after taxes)
is not necessarily indicative of how the Fund will perform in the future.

Annual Total Returns-Calendar Years

The Fund's year-to-date total return for the six months ended June 30, 2011 was
(13.35)%.

        Best Quarter                    Worst Quarter
31.54% (1st Quarter 2006)       (41.88)% (4th Quarter 2008)

After-tax returns in the table below are calculated using the historical highest
individual federal marginal income tax rates and do not reflect the impact of
state and local taxes. Actual after-tax returns depend on an investor's tax
situation and may differ from those shown, and after-tax returns shown are not
relevant to investors who hold Shares through tax-deferred arrangements, such as
401(k) plans or individual retirement accounts. In the event of negative
performance displayed in the table below, the Fund's returns after taxes on
distributions and sale of Fund Shares are calculated assuming that an investor
has sufficient capital gains of the same character from other investments to
offset any capital losses from the sale of Fund Shares so that the investor may
deduct the losses in full. As a result, the Fund's returns after taxes on
distributions and sale of Fund Shares may exceed the Fund's returns before
taxes and/or returns after taxes on distributions.

[1] Invesco PowerShares Capital Management LLC (the "Adviser") has agreed to waive fees and/or pay Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, brokerage commissions and other trading expenses, sub-licensing fees, offering costs, taxes and extraordinary expenses) from exceeding 0.60% of the Fund's average daily net assets per year (the "Expense Cap") until at least August 31, 2012, and neither the Adviser nor the Fund can discontinue the agreement prior to its expiration. The expenses borne by the Adviser are subject to recapture by the Adviser for up to three years from the date the fee or expense was borne by the Adviser, but no recapture payment will be made by the Fund if it would result in the Fund exceeding its Expense Cap.

Investment Strategy, Heading	rr_StrategyHeading	Principal Investment Strategies
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 80% of its total assets in preferred securities of financial institutions. The Fund generally will invest at least 90% of its total assets in preferred securities that comprise the Underlying Index. The Underlying Index is a market capitalization weighted index designed to track the performance of preferred securities issued in the U.S. market by financial institutions. As of June 30, 2011, the Underlying Index was composed of preferred securities of approximately 22 financial institutions that have received an industrial sector classification of "financial" from the Bloomberg Professional Service. Strictly in accordance with its existing guidelines and mandated procedures, Wells Fargo Securities, LLC (together with Wells Fargo & Company, the "Index Provider") includes securities in the Underlying Index pursuant to a proprietary selection methodology. As of June 30, 2011, the Underlying Index included companies with a market capitalization range of between approximately $4 billion and $150 billion. Preferred securities have a payment priority over common stock in the payment of specified dividends and in the event of the issuer's liquidation. Dividends generally are paid on a fixed rate percentage of the fixed par value at which the preferred stock is issued, and preferred stocks generally have a liquidation value that equals the original purchase price of the stock at the time of issuance. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.

Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. Financial Sector Risk. The market value of securities of issuers in the financial sector can be affected by factors such as adverse regulatory or economic occurrences affecting the financial sector, availability of credit, fluctuations in asset values, unstable interest rates, increased competition, continuing consolidations and development of new products and structures. Furthermore, increased government involvement in financial institutions, including measures such as taking ownership positions in such institutions, could result in a dilution in the value of the shares held by shareholders in such institutions. Foreign Financial Institution Risk. Certain of the companies that comprise the Underlying Index, while traded on U.S. exchanges, may be issued by foreign financial institutions. Therefore, the Fund may be subject to the risks of investing in securities issued by foreign companies. High Yield Securities Risk. High yield securities typically involve greater risk and are less liquid than higher grade issues. Changes in general economic conditions, changes in the financial condition of the issuers and changes in interest rates may adversely impact the ability of issuers of high yield securities to make timely payments of interest and principal. Preferred Securities Risk. There are special risks associated with investing in preferred securities. Preferred securities may include provisions that permit the issuer, in its discretion, to defer or omit distributions for a certain period of time. If the Fund owns a security that is deferring or omitting its distributions, the Fund may be required to report the distribution on its tax returns, even though it may not have received any income. Further, preferred securities may lose substantial value due to the omission or deferment of dividend payments. Preferred securities may be less liquid than many other securities, such as common stocks, and generally offer no voting rights with respect to the issuer. Preferred securities also may be subordinated to bonds or other debt instruments in an issuer's capital structure, subjecting them to a greater risk of non-payment than more senior securities. In addition, in certain circumstances, an issuer of preferred securities may redeem the securities prior to a specified date, and this may negatively impact the return of the security. Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Concentration Risk. A significant percentage of the Underlying Index may be composed of issuers in a single industry or sector of the economy. If the Fund is focused in an industry or sector, it may present more risks than if it were diversified broadly over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries or the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Index resulting from legal restrictions, cost or liquidity constraints. For example, because the Fund's Underlying Index does not meet the diversification requirements set forth in the Internal Revenue Code relating to regulated investment companies, the Fund may not be able to invest in all of the stocks comprising its Underlying Index in proportion to their weightings in the Underlying Index at all times. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming. Small and Medium Capitalization Company Risk. Investing in securities of small and medium capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Often small and medium capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund.

Portfolio Turnover	rr_PortfolioTurnoverTextBlock	The Fund pays transaction costs, such as commissions, when it purchases and sells securities (or "turns over" its portfolio). A higher portfolio turnover will cause the Fund to incur additional transaction costs and may result in higher taxes when Fund Shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the example, may affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 91% of the average value of its portfolio.

This example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your Shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The cost under the one year example is equal to the Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the first year and the Total Annual Fund Operating Expenses thereafter.

Investment Strategy, Heading	rr_StrategyHeading	Principal Investment Strategies
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 90% of its total assets in securities that comprise the Underlying Index. The Underlying Index is composed of approximately 40 stocks of high quality companies selected by Morningstar. The securities Morningstar includes in the Underlying Index are required to have market capitalizations in excess of $100 million, be listed on a major U.S. exchange and have underlying businesses with a Morningstar® Economic Moat® Rating of narrow or wide and a Morningstar Rating® for stocks of at least 4-stars. As of June 30, 2011, the Underlying Index included common stocks of approximately 40 companies with a market capitalization range of between approximately $1.29 billion and $401 billion. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.

The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Risk, Heading	rr_RiskHeading	Principal Risks of the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Index may be composed of issuers in a single industry or sector of the economy. If the Fund is focused in an industry or sector, it may present more risks than if it were broadly diversified over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries of the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Index resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming. Small and Medium Capitalization Company Risk. Investing in securities of small and medium capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Often small and medium capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater portion of assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in share price than would occur in a diversified fund. This may increase the Fund's volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund's performance. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC or any other government agency.

PowerShares Morningstar StockInvestor Core Portfolio (Prospectus Summary) | PowerShares Morningstar StockInvestor Core Portfolio

PowerShares Morningstar StockInvestor Core Portfolio

Investment Objective

The PowerShares Morningstar StockInvestor Core Portfolio (the "Fund") seeks
investment results that generally correspond (before fees and expenses) to the
price and yield of the Morningstar® StockInvestor Core IndexSM* (the "Underlying
Index").

* Morningstar® StockInvestor Core IndexSM and Morningstar are service marks of
Morningstar, Inc. ("Morningstar") and have been licensed for use for certain
purposes by the Adviser. The Fund is not sponsored, endorsed, sold or promoted
by Morningstar, and Morningstar makes no representation regarding the
advisability of investing in the Fund.

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors may pay brokerage commissions on their
purchases and sales of Shares, which are not reflected in the table or the
example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		PowerShares Morningstar StockInvestor Core Portfolio
Management Fees		0.50%
Other Expenses		1.31%
Total Annual Fund Operating Expenses		1.81%
Fee Waiver and/or Expense Assumption	[1]	1.28%
Total Annual Fund Operating Expenses After Fee Waiver and Expense Assumption	[1]	0.53%

Example

This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. This example assumes that you invest
$10,000 in the Fund for the time periods indicated and then sell all of your
Shares at the end of those periods. The example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. The cost under the one year example is equal to the Total
Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the
first year and the Total Annual Fund Operating Expenses thereafter. This example
does not include the brokerage commissions that investors may pay to buy and
sell Shares of the Fund.

Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Expense Example (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
PowerShares Morningstar StockInvestor Core Portfolio	54	445	862	2,025

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover rate was 91% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 90% of its total assets in securities
that comprise the Underlying Index. The Underlying Index is composed of
approximately 40 stocks of high quality companies selected by Morningstar. The
securities Morningstar includes in the Underlying Index are required to have
market capitalizations in excess of $100 million, be listed on a major U.S.
exchange and have underlying businesses with a Morningstar® Economic Moat®
Rating of narrow or wide and a Morningstar Rating® for stocks of at least
4-stars. As of June 30, 2011, the Underlying Index included common stocks of
approximately 40 companies with a market capitalization range of between
approximately $1.29 billion and $401 billion.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying Index
reflects a concentration in that industry or group of industries. The Fund will
not otherwise concentrate its investments in securities of issuers in any one
industry or group of industries.

Principal Risks of the Fund

The following summarizes the principal risks of the Fund.

Market Risk. Securities in the Underlying Index are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Index.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets, and disruption in the creation/redemption process of the
Fund. Any of these factors may lead to the Shares trading at a premium or
discount to the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock
in the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a company's
capital structure, in terms of priority to corporate income, and therefore will
be subject to greater dividend risk than preferred stocks or debt instruments
of such issuers.

Concentration Risk. A significant percentage of the Underlying Index may be
composed of issuers in a single industry or sector of the economy. If the Fund
is focused in an industry or sector, it may present more risks than if it were
broadly diversified over numerous industries and sectors of the economy. At
times, such industry or group of industries may be out of favor and underperform
other industries of the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Index for a number of reasons. For example, the Fund incurs operating
expenses not applicable to the Underlying Index, and incurs costs in buying and
selling securities, especially when rebalancing the Fund's securities holdings
to reflect changes in the composition of the Underlying Index. In addition, the
performance of the Fund and the Underlying Index may vary due to asset valuation
differences and differences between the Fund's portfolio and the Underlying
Index resulting from legal restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Index.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Index, even if that
security generally is underperforming.

Small and Medium Capitalization Company Risk. Investing in securities of small
and medium capitalization companies involves greater risk than customarily is
associated with investing in larger, more established companies. These
companies' securities may be more volatile and less liquid than those of more
established companies. These securities may have returns that vary, sometimes
significantly, from the overall securities market. Often small and medium
capitalization companies and the industries in which they focus are still
evolving and, as a result, they may be more sensitive to changing market
conditions.

Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater
portion of assets in securities of individual issuers than a diversified fund.
As a result, changes in the market value of a single investment could cause
greater fluctuations in share price than would occur in a diversified fund. This
may increase the Fund's volatility and cause the performance of a relatively
small number of issuers to have a greater impact on the Fund's performance.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC
or any other government agency.

Performance

The bar chart below shows how the Fund has performed. The table below the bar
chart shows the Fund's average annual total returns (before and after taxes).
The bar chart and table provide an indication of the risks of investing in the
Fund by showing how the Fund's total return has varied from year to year and by
showing how the Fund's average annual total returns compared with a broad
measure of market performance. The Fund's performance reflects fee waivers, if
any, absent which, performance would have been lower. Although the information
shown in the bar chart and the table gives you some idea of the risks involved
in investing in the Fund, the Fund's past performance (before and after taxes)
is not necessarily indicative of how the Fund will perform in the future.
Updated performance information is available online at
www.InvescoPowerShares.com.

After-tax returns in the table below are calculated using the historical highest
individual federal marginal income tax rates and do not reflect the impact of
state and local taxes. Actual after-tax returns depend on an investor's tax
situation and may differ from those shown, and after-tax returns shown are not
relevant to investors who hold Shares through tax-deferred arrangements, such as
401(k) plans or individual retirement accounts. In the event of negative
performance displayed in the table below, the Fund's returns after taxes on
distributions and sale of Fund Shares are calculated assuming that an investor
has sufficient capital gains of the same character from other investments to
offset any capital losses from the sale of Fund Shares so that the investor may
deduct the losses in full. As a result, the Fund's returns after taxes on
distributions and sale of Fund Shares may exceed the Fund's returns before taxes
and/or returns after taxes on distributions.

PowerShares Fundamental Pure Large Growth Portfolio (Prospectus Summary) | PowerShares Fundamental Pure Large Growth Portfolio

PowerShares Fundamental Pure Large Growth Portfolio

Investment Objective

The PowerShares Fundamental Pure Large Growth Portfolio (the "Fund") seeks
investment results that generally correspond (before fees and expenses) to the
price and yield of the RAFI® Fundamental Large Growth Index (the "Underlying
Index").

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors may pay brokerage commissions on their
purchases and sales of Shares, which are not reflected in the table or the
example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		PowerShares Fundamental Pure Large Growth Portfolio
Management Fees		0.29%
Other Expenses	[1]	0.16%
Total Annual Fund Operating Expenses		0.45%
Fee Waivers and Expense Assumption	[2]	0.06%
Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption	[2]	0.39%

Example

This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. This example assumes that you invest
$10,000 in the Fund for the time periods indicated and then sell all of your
Shares at the end of those periods. The example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. The cost under the one year example is equal to the Total
Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the
first year and the Total Annual Fund Operating Expenses thereafter. This example
does not include the brokerage commissions that investors may pay to buy and
sell Shares of the Fund.

Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Expense Example (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years
PowerShares Fundamental Pure Large Growth Portfolio	40	138

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Shares are held in a taxable account. These costs, which are
not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. As of the most recent fiscal year end, the Fund
had not commenced operations and therefore no portfolio turnover data is
available.

Principal Investment Strategies

The Fund generally will invest at least 90% of its total assets in the component
securities that comprise the Underlying Index. The Underlying Index is comprised
of common stocks of "large growth" U.S. companies (including real estate
investment trusts ("REITs")) that Research Affiliates, LLC ("RAFI Affiliates" or
the "Index Provider") classifies based on its Fundamental Index® methodology.
Strictly in accordance with its existing guidelines and mandated procedures, the
Index Provider identifies the common stocks for inclusion in the Underlying
Index from a universe of the 2,500 largest U.S. companies. The use of the word
"Fundamental" in the Fund's name reflects the fact that, in identifying the
common stocks, the Index Provider uses fundamental measures of company size
rather than market capitalization (company share price multiplied by number of
shares outstanding). The Index Provider uses the following fundamental measures
to include common stocks in the Underlying Index: book value, income, sales and
dividends. The Index Provider calculates a composite fundamental weight for each
common stock by equally weighting the above four fundamental measures. The Index
Provider ranks each common stock by its fundamental weight and, based on this
ranking, divides the common stocks into three size groups: "large," "mid" and
"small." The common stocks it ranks in the top 70% of the eligible universe by
fundamental weight comprise the "large" size group, the next 20% comprise the
"mid" size group, and the final 10% comprise the "small" size group. The Index
Provider divides the "large" size group further into "growth," "core" or "value"
subsets based on the Fundamental Index® methodology style score, which uses a
combination of fundamental growth rates and fundamental valuation ratios. The
Underlying Index is composed only of those common stocks that the Index Provider
classifies as both "large" and "growth." The Fund generally will invest at least
80% of its total assets in common stocks of "fundamentally large" companies. The
Fund considers "fundamentally large" companies to be those companies that
comprise the Underlying Index.

The use of the word "Pure" in the Fund's name reflects that, in selecting
securities for the Underlying Index, the Index Provider includes only those
securities that it has classified as "growth." Although "growth" funds also
could include some stocks that, based on their classification, would be
considered "core" or "value," the Underlying Index contains only those stocks
that the Index Provider classifies as pure "growth" stocks. The Fund generally
will invest in all of the securities comprising its Underlying Index in
proportion to their weightings in the Underlying Index.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its net assets) in securities of issuers in any one
industry or group of industries only to the extent that the Underlying Index
reflects a concentration in that industry or group of industries. The Fund will
not otherwise concentrate its investments in securities of issuers in any one
industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

"Fundamentally Large" Company Risk. Returns on investments in common stocks of
"fundamentally large" U.S. companies could trail the returns on investments in
common stocks of smaller companies or other large companies based on market
capitalization.

Growth Risk. The market values of "growth" securities may be more volatile than
other types of investments. The returns on "growth" securities may or may not
move in tandem with the returns on other styles of investing or the overall
stock market. Thus, the value of the Fund's investments will vary and at times
may be lower or higher than that of other types of investments.

REIT Risk. Although the Fund will not invest in real estate directly, the REITs
in which the Fund invests are subject to risks inherent in the direct ownership
of real estate. These risks include, but are not limited to, a possible lack of
mortgage funds and associated interest rate risks, overbuilding, property
vacancies, increases in property taxes and operating expenses, changes in zoning
laws, losses due to environmental damages and changes in neighborhood values and
appeal to purchasers.

Market Risk. Securities in the Underlying Index are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Index.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets, and disruption in the creation/redemption process of the
Fund. Any of these factors may lead to the Shares trading at a premium or
discount to the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or debt
instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Index may be
comprised of issuers in a single industry or sector of the economy. If the Fund
is focused in an industry or sector, it may present more risks than if it were
broadly diversified over numerous industries and sectors of the economy. At times,
such industry or group of industries may be out of favor and underperform other
industries of the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Index for a number of reasons. For example, the Fund incurs operating
expenses not applicable to the Underlying Index, and incurs costs in buying and
selling securities, especially when rebalancing the Fund's securities holdings

Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Index, even if that
security generally is underperforming.

Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater
portion of its assets in securities of individual issuers than a diversified
fund. As a result, changes in the market value of a single investment could
cause greater fluctuations in Share price than would occur in a diversified
fund. This may increase the Fund's volatility and cause the performance of a
relatively small number of issuers to have a greater impact on the Fund's
performance.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the
Federal Deposit Insurance Corporation or any other government agency.

Performance

The Fund commenced operations on May 25, 2011 and therefore does not have
performance history for a full calendar year. Once the Fund has a full calendar
year of performance, the Fund will present total return information, which also
is accessible on the Fund's website at www.InvescoPowerShares.com and provides
some indication of the risks of investing in the Fund.

[1] "Other Expenses" are based on estimated amounts for the current fiscal year.

[2] Invesco PowerShares Capital Management LLC (the "Adviser") has agreed to waive fees and/or pay Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, offering costs, brokerage commissions and other trading expenses, taxes and extraordinary expenses) from exceeding 0.39% of the Fund's average daily net assets per year (the "Expense Cap") until at least August 31, 2012, and neither the Adviser nor the Fund can discontinue the agreement prior to its expiration. The expenses borne by the Adviser are subject to recapture by the Adviser for up to three years from the date the fee or expense was borne by the Adviser, but no recapture payment will be made by the Fund if it would result in the Fund exceeding its Expense Cap.

Investment Strategy, Heading	rr_StrategyHeading	Principal Investment Strategies
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 80% of its total assets in common stocks of consumer companies. The Fund generally will invest at least 90% of its total assets in common stocks that comprise the Underlying Intellidex. As of June 30, 2011, the Underlying Intellidex was comprised of stocks of 60 U.S. consumer companies. These companies are principally engaged in the businesses of providing consumer goods and services that are cyclical in nature, including retail, automotive, leisure and recreation, media and real estate. Strictly in accordance with its existing guidelines and mandated procedures, NYSE Arca, Inc. ("NYSE Arca" or the "Intellidex Provider") includes stocks principally on the basis of their capital appreciation potential that it identifies pursuant to a proprietary Intellidex methodology. As of June 30, 2011, the Underlying Intellidex included common stocks of companies with a market capitalization range of between $322 million and $53 billion. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Intellidex reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Investment Strategy, Portfolio Concentration	rr_StrategyPortfolioConcentration	The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Intellidex reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. Consumer Discretionary Sector Risk. Companies engaged in the consumer discretionary sector are affected by fluctuations in supply and demand. Changes in consumer spending as a result of world events, political and economic conditions, commodity price volatility, changes in exchange rates, imposition of import controls, increased competition, depletion of resources and labor relations also may adversely affect these companies. Market Risk. Securities in the Underlying Intellidex are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Intellidex. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Intellidex is comprised of issuers in a single industry or sector of the economy. By focusing in an industry or sector, the Fund faces more risks than if it were diversified broadly over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries or the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Intellidex for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Intellidex, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Intellidex. In addition, the performance of the Fund and the Underlying Intellidex may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Intellidex resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Intellidex. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Intellidex, even if that security generally is underperforming. Small and Medium Capitalization Company Risk. Investing in securities of small and medium capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Often small and medium capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC or any other government agency.

PowerShares Dynamic Large Cap Growth Portfolio (Prospectus Summary) | PowerShares Dynamic Large Cap Growth Portfolio

PowerShares Dynamic Large Cap Growth Portfolio

Investment Objective

The PowerShares Dynamic Large Cap Growth Portfolio (the "Fund") seeks investment
results that generally correspond (before fees and expenses) to the price and
yield of the Dynamic Large Cap Growth IntellidexSM Index (the "Underlying
Intellidex").

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors may pay brokerage commissions on their
purchases and sales of Shares, which are not reflected in the table or the
example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		PowerShares Dynamic Large Cap Growth Portfolio
Management Fees		0.50%
Other Expenses		0.14%
Total Annual Fund Operating Expenses		0.64%
Fee Waivers and Expense Assumption	[1]	0.01%
Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption	[1]	0.63%

Example

This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. This example assumes that you invest
$10,000 in the Fund for the time periods indicated and then sell all of your
Shares at the end of those periods. The example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. The cost under the one year example is equal to the Total
Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the
first year and the Total Annual Fund Operating Expenses thereafter. This example
does not include the brokerage commissions that investors may pay to buy and sell
Shares of the Fund.

Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Expense Example (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
PowerShares Dynamic Large Cap Growth Portfolio	64	204	356	797

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover rate was 45% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 80% of its total assets in common stocks
of large capitalization companies. NYSE Arca, Inc. ("NYSE Arca" or the
"Intellidex Provider") considers a company to be a large capitalization company
if it falls within the Underlying Intellidex model, as described below. The Fund
generally will invest at least 90% of its total assets in common stocks that
comprise the Underlying Intellidex. As of June 30, 2011, the Underlying
Intellidex was composed of 50 large capitalization U.S. growth stocks that,
strictly in accordance with its existing guidelines and mandated procedures,
NYSE Arca included principally on the basis of their capital appreciation
potential that NYSE Arca identifies pursuant to a proprietary Intellidex
methodology. As of June 30, 2011, the Underlying Intellidex included common
stocks of companies with a market capitalization range of between approximately
$10 billion and $311 billion.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying
Intellidex reflects a concentration in that industry or group of industries. The
Fund will not otherwise concentrate its investments in securities of issuers in
any one industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Growth Investing Style Risk. The market values of "growth" securities may be
more volatile than other types of investments. The returns on "growth"
securities may or may not move in tandem with the returns on other styles of
investing or the overall stock market. Thus, the value of the Fund's investments
will vary and at times may be lower or higher than that of other types of
investments.

Market Risk. Securities in the Underlying Intellidex are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Intellidex.

Market Trading Risk. The Fund faces market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets, and disruption in the creation/redemption process of the
Fund. Any of these factors may lead to the Shares trading at a premium or discount
to the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or debt
instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Intellidex may be
composed of issuers in a single industry or sector of the economy. If the Fund
is focused in an industry or sector, it may present more risks than if it were
diversified broadly over numerous industries and sectors of the economy. At
times, such industry or group of industries may be out of favor and underperform
other industries or the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Intellidex for a number of reasons. For example, the Fund incurs
operating expenses not applicable to the Underlying Intellidex, and incurs costs
in buying and selling securities, especially when rebalancing the Fund's
securities holdings to reflect changes in the composition of the Underlying
Intellidex. In addition, the performance of the Fund and the Underlying
Intellidex may vary due to asset valuation differences and differences between
the Fund's portfolio and the Underlying Intellidex resulting from legal
restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Intellidex.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Intellidex, even if that
security generally is underperforming.

Large Capitalization Company Risk. Companies with large market capitalizations
may go in and out of favor based on market and economic conditions. Although
larger companies tend to be less volatile than companies with smaller market
capitalizations, returns on investments in securities of large capitalization
U.S. companies could trail the returns on investments in stocks of smaller
companies.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC
or any other government agency.

Powershares S&P 500 BuyWrite Portfolio	77	240	417	930

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover was 61% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 80% of its total assets in common stocks
of the 500 companies included in the S&P 500® Index (the "S&P 500 Index" or the
"Reference Index") and will write (sell) call options thereon. The Underlying
Index measures total returns of a theoretical portfolio including the S&P 500
Index stocks on which S&P 500 Index call options are written (sold) systemically
against the portfolio through a "buy-write" strategy. A "buy-write," also called
a covered call, generally is considered an investment strategy in which an
investor buys a stock or basket of stocks, and sells call options that
correspond to the stock or basket of stocks. In return for a premium, the Fund
gives the right to the purchaser of the option written by the Fund to receive a
cash payment equal to the difference between the value of the S&P 500 Index and
the exercise price, if the value on the expiration date is above the exercise
price. In addition, covered call options partially hedge against a decline in
the price of the securities on which they are written to the extent of the
premium the Fund receives. The Fund will write options that are traded on
national securities exchanges. Strictly in accordance with its existing
guidelines and mandated procedures, the Chicago Board Options Exchange (the
"CBOE" or the "Index Provider") calculates the Underlying Index. As of June 30,
2011, the S&P 500 Index included common stocks of 500 companies with a market
capitalization range of between approximately $1.4 billion and $400.9 billion.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying Index
reflects a concentration in that industry or group of industries. The Fund will
not otherwise concentrate its investments in securities of issuers in any one
industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Writing Covered Call Option Risk. By writing covered call options in return for
the receipt of premiums, the Fund will give up the opportunity to benefit from
potential increases in the value of the S&P 500 Index above the exercise prices
of the Written Options, but will continue to bear the risk of declines in the
value of the S&P 500 Index. The premiums received from the options may not be
sufficient to offset any losses sustained from the volatility of the underlying
stocks over time. In addition, the Fund's ability to sell the underlying
securities will be limited while the option is in effect unless the Fund
extinguishes the option position through the purchase of an offsetting identical
option prior to the expiration of the written option. Exchanges may suspend the
trading of options in volatile markets. If trading is suspended, the Fund may be
unable to write options at times that may be desirable or advantageous to the
Fund to do so.

U.S. Federal Income Tax Risk. Due to its investment strategy and U.S. federal
income tax elections, the Fund expects to account for gains or losses on its
investments on a daily mark-to-market basis for federal income tax purposes.
Generally, the mark-to-market gains and losses from the stock positions will be
compared with the mark-to-market gains or losses from the call options on a
daily basis. To the extent that there is more gain or loss from the stock
positions, the Fund will have short term capital gain, which generally is taxed
like ordinary income, or short term capital loss. To the extent there is
more gain or loss from the call options, such gain will be 60% long term capital
gain or loss and 40% short term capital gain. These rules also impose limits on
the total percentage of gain for the tax year that can be characterized as long
term capital gain and the percentage of loss for the tax year that can be
characterized as short term capital loss. As a result of its investment
strategy, the Fund will not be able to designate a portion of its dividends as
being eligible for lower rates of tax in the hands of non-corporate shareholders
(dividends that are commonly referred to as "qualified dividend income") or as
being eligible for the dividends received deduction when received by certain
corporate shareholders. For these reasons, a significant portion of income
received from the Fund may be subject to tax at greater rates than would apply
if the Fund were engaged in a different investment strategy. You should consult
your tax advisors as to the tax consequences of acquiring, owning and disposing
of shares in the Fund.

Market Risk. Securities in the Underlying Index are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Index.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets, and disruption in the creation/redemption process of the
Fund. Any of these factors may lead to the Shares trading at a premium or
discount to the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or debt
instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Index may be
composed of issuers in a single industry or sector of the economy. If the Fund
is focused in an industry or sector, it may present more risks than if it were
broadly diversified over numerous industries and sectors of the economy. At
times, such industry or group of industries may be out of favor and underperform
other industries of the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Index for a number of reasons. For example, the Fund incurs operating
expenses not applicable to the Underlying Index, and incurs costs in buying and
selling securities, especially when rebalancing the Fund's securities holdings
to reflect changes in the composition of the Underlying Index. In addition, the
performance of the Fund and the Underlying Index may vary due to asset valuation
differences and differences between the Fund's portfolio and the Underlying
Index resulting from legal restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Index.
Therefore, it would not necessarily buy or sell a security unless that
security is added or removed, respectively, from the Underlying Index,
even if that security generally is underperforming.

Large Capitalization Company Risk. Returns on investments in securities of large
capitalization U.S. companies could trail the returns on investments in stocks
of smaller companies.

Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater
portion of its assets in securities of individual issuers than a diversified
fund. As a result, changes in the market value of a single investment could
cause greater fluctuations in Share price than would occur in a diversified
fund. This may increase the Fund's volatility and cause the performance of a
relatively small number of issuers to have a greater impact on the Fund's
performance.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC
or any other government agency.

PowerShares Fundamental Pure Large Value Portfolio (Prospectus Summary) | PowerShares Fundamental Pure Large Value Portfolio

PowerShares Fundamental Pure Large Value Portfolio

Investment Objective

The PowerShares Fundamental Pure Large Value Portfolio (the "Fund") seeks
investment results that generally correspond (before fees and expenses) to the
price and yield of the RAFI® Fundamental Large Value Index (the "Underlying
Index").

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors may pay brokerage commissions on their
purchases and sales of Shares, which are not reflected in the table or the
example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		PowerShares Fundamental Pure Large Value Portfolio
Management Fees		0.29%
Other Expenses	[1]	0.16%
Total Annual Fund Operating Expenses		0.45%
Fee Waivers and Expense Assumption	[2]	0.06%
Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption	[2]	0.39%

Example

This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. This example assumes that you invest
$10,000 in the Fund for the time periods indicated and then sell all of your
Shares at the end of those periods. The example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. The cost under the one year example is equal to the Total
Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the
first year and the Total Annual Fund Operating Expenses thereafter. This example
does not include the brokerage commissions that investors may pay to buy and
sell Shares of the Fund.

Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Expense Example (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years
PowerShares Fundamental Pure Large Value Portfolio	40	138

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Shares are held in a taxable account. These costs, which are
not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. As of the most recent fiscal year end, the Fund
had not commenced operations and therefore no portfolio turnover data is
available.

Principal Investment Strategies

The Fund generally will invest at least 90% of its total assets in the component
securities that compose the Underlying Index. The Underlying Index is comprised
of common stocks of "large value" U.S. companies (including real estate
investment trusts ("REITs")) that Research Affiliates, LLC ("RAFI Affiliates" or
the "Index Provider") classifies based on its Fundamental Index® methodology.
Strictly in accordance with its existing guidelines and mandated procedures, the
Index Provider identifies the common stocks for inclusion in the Underlying
Index from a universe of the 2,500 largest U.S. companies. The use of the word
"Fundamental" in the Fund's name reflects the fact that, in identifying the
common stocks, the Index Provider uses fundamental measures of company size,
rather than market capitalization (company share price multiplied by number of
shares outstanding). The Index Provider uses the following fundamental measures
to include common stocks in the Underlying Index: book value, income, sales and
dividends. The Index Provider calculates a composite fundamental weight for each
common stock by equally weighting the above four fundamental measures. The Index
Provider ranks each common stock by its fundamental weight and, based on this
ranking, divides common stocks into three size groups: "large," "mid" and
"small." The common stocks it ranks in the top 70% of the eligible universe by
fundamental weight comprise the "large" size group, the next 20% comprise the
"mid" size group, and the final 10% comprise the "small" size group. The Index
Provider divides the "large" size group further into "growth," "core" or "value"
subsets based on the Fundamental Index® methodology style score, which uses a
combination of fundamental growth rates and fundamental valuation ratios. The
Underlying Index is composed only of those common stocks that the Index Provider
classifies as both "large" and "value." The Fund generally will invest at least
80% of its total assets in common stocks of "fundamentally large" companies. The
Fund considers "fundamentally large" companies to be those companies that
comprise the Underlying Index.

The use of the word "Pure" in the Fund's name reflects that, in selecting
securities for the Underlying Index, the Index Provider includes only those
securities that it has classified as "value." Although "value" funds also could
include some stocks that, based on their classification, would be considered
"growth" or "core," the Underlying Index contains only those stocks that the
Index Provider classifies as pure "value" stocks. The Fund generally will invest
in all of the securities comprising its Underlying Index in proportion to their
weightings in the Underlying Index.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its net assets) in securities of issuers in any one
industry or group of industries only to the extent that the Underlying Index
reflects a concentration in that industry or group of industries. The Fund will
not otherwise concentrate its investments in securities of issuers in any one
industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

"Fundamentally Large" Company Risk. Returns on investments in common stocks of
"fundamentally large" U.S. companies could trail the returns on investments in
common stocks of smaller companies or other large companies based on market
capitalization.

REIT Risk. Although the Fund will not invest in real estate directly, the REITs
in which the Fund invests are subject to risks inherent in the direct ownership
of real estate. These risks include, but are not limited to, a possible lack of
mortgage funds and associated interest rate risks, overbuilding, property
vacancies, increases in property taxes and operating expenses, changes in zoning
laws, losses due to environmental damages and changes in neighborhood values and
appeal to purchasers.

Value Risk. "Value" securities are subject to the risk that the valuations never
improve or that the returns on "value" securities are less than returns on other
styles of investing or the overall stock market. Thus, the value of the Fund's
investments will vary and at times may be lower or higher than that of other
types of investments.

Market Risk. Securities in the Underlying Index are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Index.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets, and disruption in the creation/redemption process of the
Fund. Any of these factors may lead to the Shares trading at a premium or
discount to the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or debt
instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Index may be
comprised of issuers in a single industry or sector of the economy. If the Fund
is focused in an industry or sector, it may present more risks than if it were
broadly diversified over numerous industries and sectors of the economy. At times,
such industry or group of industries may be out of favor and underperform other
industries of the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Index for a number of reasons. For example, the Fund incurs operating
expenses not applicable to the Underlying Index, and incurs costs in buying and
selling securities, especially when rebalancing the Fund's securities holdings
to reflect changes in the composition of the Underlying Index. In addition, the
performance of the Fund and the Underlying Index may vary due to asset valuation
differences and differences between the Fund's portfolio and the Underlying
Index resulting from legal restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Index.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Index, even if that
security generally is underperforming.

Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater
portion of its assets in securities of individual issuers than a diversified
fund. As a result, changes in the market value of a single investment could
cause greater fluctuations in Share price than would occur in a diversified
fund. This may increase the Fund's volatility and cause the performance of a
relatively small number of issuers to have a greater impact on the Fund's
performance.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the
Federal Deposit Insurance Corporation or any other government agency.

Performance

The Fund commenced operations on May 25, 2011 and therefore does not have
performance history for a full calendar year. Once the Fund has a full calendar
year of performance, the Fund will present total return information, which also
is accessible on the Fund's website at www.InvescoPowerShares.com and provides
some indication of the risks of investing in the Fund.

[1] "Other Expenses" are based on estimated amounts for the current fiscal year.

[2] Invesco PowerShares Capital Management LLC (the "Adviser") has agreed to waive fees and/or pay Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, offering costs, brokerage commissions and other trading expenses, taxes and extraordinary expenses) from exceeding 0.39% of the Fund's average daily net assets per year (the "Expense Cap") until at least August 31, 2012, and neither the Adviser nor the Fund can discontinue the agreement prior to its expiration. The expenses borne by the Adviser are subject to recapture by the Adviser for up to three years from the date the fee or expense was borne by the Adviser, but no recapture payment will be made by the Fund if it would result in the Fund exceeding its Expense Cap.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover rate was 75% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 90% of its total assets in common stocks
that comprise the Underlying Intellidex. If the composition of the Underlying
Intellidex changes, the Fund will continue to invest at least 80% of its total
assets in over-the-counter ("OTC") securities. As of June 30, 2011, the
Underlying Intellidex was composed of 100 OTC market securities that NYSE Arca,
Inc. ("NYSE Arca" or the "Intellidex Provider"), strictly in accordance with its
existing guidelines and mandated procedures, included pursuant to a proprietary
method. The Underlying Intellidex selection methodology identifies and selects
companies from The NASDAQ Stock Market LLC ("NASDAQ") with superior risk-return
profiles. As of June 30, 2011, the Underlying Intellidex included common stocks
of companies with a market capitalization range of between approximately $324
million and $42 billion.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying
Intellidex reflects a concentration in that industry or group of industries. The
Fund will not otherwise concentrate its investments in securities of issuers in
any one industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Market Risk. Securities in the Underlying Intellidex are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Intellidex.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for Shares, losses from trading in secondary
markets, and disruption in the creation/redemption process of the Fund. Any of
these factors may lead to Shares trading at a premium or discount to the Fund's
net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may depress
the value of equity securities the Fund holds; the price of common stock of an
issuer may be particularly sensitive to general movements in the stock market;
or a drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock of
an issuer in the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or debt
instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Intellidex may be
composed of issuers in a single industry or sector of the economy. If the Fund
is focused in an industry or sector, it may present more risks than if it were
broadly diversified over numerous industries and sectors of the economy. At
times, such industry or group of industries may be out of favor and underperform
other industries of the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Intellidex for a number of reasons. For example, the Fund incurs
operating expenses not applicable to the Underlying Intellidex, and incurs costs
in buying and selling securities, especially when rebalancing the Fund's
securities holdings to reflect changes in the composition of the Underlying
Intellidex. In addition, the performance of the Fund and the Underlying
Intellidex may vary due to asset valuation differences and differences between
the Fund's portfolio and the Underlying Intellidex resulting from legal
restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Intellidex.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Intellidex, even if that
security generally is underperforming.

Small and Medium Capitalization Company Risk. Investing in securities of small
and medium capitalization companies involves greater risk than customarily is
associated with investing in larger, more established companies. These
companies' securities may be more volatile and less liquid than those of more
established companies. These securities may have returns that vary, sometimes
significantly, from the overall securities market. Often small and medium
capitalization companies and the industries in which they focus are still
evolving and, as a result, they may be more sensitive to changing market
conditions.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC

PowerShares Dynamic Pharmaceuticals Portfolio (Prospectus Summary) | PowerShares Dynamic Pharmaceuticals Portfolio

PowerShares Dynamic Pharmaceuticals Portfolio

Investment Objective

The PowerShares Dynamic Pharmaceuticals Portfolio (the "Fund") seeks investment
results that generally correspond (before fees and expenses) to the price and
yield of the Dynamic Pharmaceuticals IntellidexSM Index (the "Underlying
Intellidex").

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors may pay brokerage commissions on their
purchases and sales of Shares, which are not reflected in the table or the
example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		PowerShares Dynamic Pharmaceuticals Portfolio
Management Fees		0.50%
Other Expenses		0.26%
Total Annual Fund Operating Expenses		0.76%
Fee Waivers and Expense Assumption	[1]	0.13%
Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption	[1]	0.63%

Example

This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. This example assumes that you invest
$10,000 in the Fund for the time periods indicated and then sell all of your
Shares at the end of those periods. The example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. The cost under the one year example is equal to the Total
Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the
first year and the Total Annual Fund Operating Expenses thereafter. This example
does not include the brokerage commissions that investors may pay to buy and
sell Shares of the Fund.

Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Expense Example (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
PowerShares Dynamic Pharmaceuticals Portfolio	64	230	410	930

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover rate was 9% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 80% of its total assets in common stocks
of pharmaceutical companies. The Fund generally will invest at least 90% of its
total assets in common stocks that comprise the Underlying Intellidex. As of
June 30, 2011, the Underlying Intellidex was composed of stocks of 30 U.S.
pharmaceuticals companies. These companies are engaged principally in the
research, development, manufacture, sale or distribution of pharmaceuticals and
drugs of all types. These companies may include, for example, pharmaceutical
companies and other companies involved in the research, development,
manufacture, sale or distribution of drugs, including companies that facilitate
the testing or regulatory approval of drugs. Strictly in accordance with its
existing guidelines and mandated procedures, the Intellidex Provider includes
stocks principally on the basis of their capital appreciation potential that it
identifies pursuant to a proprietary Intellidex methodology. As of June 30,
2011, the Underlying Intellidex included common stocks of companies with a
market capitalization range of between approximately $351 million and $182
billion.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying
Intellidex reflects a concentration in that industry or group of industries. The
Fund will not otherwise concentrate its investments in securities of issuers in
any one industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Pharmaceuticals Industry Concentration Risk. Government approval of products and
services, government regulation and reimbursement rates, product liability
claims, patent expirations and protection and intense competition can
significantly affect the pharmaceuticals industry.

Market Risk. Securities in the Underlying Intellidex are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Intellidex.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets, and disruption in the creation/redemption process of the Fund.
Any of these factors may lead to the Shares trading at a premium or discount to
the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or debt
instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Intellidex is
comprised of issuers in a single industry or sector of the economy. By focusing
in an industry or sector, the Fund faces more risks than if it were diversified
broadly over numerous industries and sectors of the economy. At times, such
industry or group of industries may be out of favor and underperform other
industries or the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Intellidex for a number of reasons. For example, the Fund incurs
operating expenses not applicable to the Underlying Intellidex, and incurs costs
in buying and selling securities, especially when rebalancing the Fund's
securities holdings to reflect changes in the composition of the Underlying
Intellidex. In addition, the performance of the Fund and the Underlying
Intellidex may vary due to asset valuation differences and differences between
the Fund's portfolio and the Underlying Intellidex resulting from legal
restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Intellidex.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Intellidex, even if that
security generally is underperforming.

Small and Medium Capitalization Company Risk. Investing in securities of small
and medium capitalization companies involves greater risk than customarily is
associated with investing in larger, more established companies. These
companies' securities may be more volatile and less liquid than those of more
established companies. These securities may have returns that vary, sometimes
significantly, from the overall securities market. Often small and medium
capitalization companies and the industries in which they focus are still
evolving and, as a result, they may be more sensitive to changing market
conditions.

Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater
portion of its assets in securities of individual issuers than a diversified
fund. As a result, changes in the market value of a single investment could
cause greater fluctuations in Share price than would occur in a diversified
fund. This may increase the Fund's volatility and cause the performance of a
relatively small number of issuers to have a greater impact on the Fund's
performance.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC
or any other government agency.

Performance

The bar chart and table provide an indication of the risks of investing in the
Fund by showing how the Fund's total return has varied from year to year and by
showing how the Fund's average annual total returns compared with a broad
measure of market performance. The Fund's performance reflects fee waivers, if
any, absent which, performance would have been lower. Although the information
shown in the bar chart and the table gives you some idea of the risks involved
in investing in the Fund, the Fund's past performance (before and after taxes)
is not necessarily indicative of how the Fund will perform in the future.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover was 63% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 80% of its total assets in common stocks
of healthcare companies. The Fund generally will invest at least 90% of its
total assets in common stocks that comprise the Underlying Intellidex. As of
June 30, 2011, the Underlying Intellidex was comprised of stocks of 60 U.S.
healthcare companies. These companies are principally engaged in the business of
providing healthcare-related products and services, including biotechnology,
pharmaceuticals, medical technology and supplies, and facilities. Strictly in
accordance with its existing guidelines and mandated procedures, NYSE Arca, Inc.
("NYSE Arca" or the "Intellidex Provider") includes stocks principally on the
basis of their capital appreciation potential that it identifies pursuant to a
proprietary Intellidex methodology. As of June 30, 2011, the Underlying
Intellidex included common stocks of companies with a market capitalization
range of between $445 million and $161 billion.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying
Intellidex reflects a concentration in that industry or group of industries. The
Fund will not otherwise concentrate its investments in securities of issuers in
any one industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Healthcare Sector Risk. Factors such as extensive government regulation,
restrictions on government reimbursement for medical expenses, rising costs of
medical products and services, pricing pressure, an increased emphasis on
outpatient services, limited number of products, industry innovation, costs
associated with obtaining and protecting patents, product liability and other
claims, changes in technologies and other market developments can affect
companies in the healthcare sector.

Market Risk. Securities in the Underlying Intellidex are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Intellidex.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets and disruption in the creation/redemption process of the Fund.
Any of these factors may lead to the Shares trading at a premium or discount to

Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 90% of its total assets in the component securities that comprise the Underlying Index. The Underlying Index is comprised of common stocks of "mid core" U.S. companies (including real estate investment trusts ("REITs")) that Research Affiliates, LLC ("RAFI Affiliates" or the "Index Provider") classifies based on the its Fundamental Index® methodology. Strictly in accordance with its existing guidelines and mandated procedures, the Index Provider identifies the common stocks for inclusion in the Underlying Index from a universe of the 2,500 largest U.S. companies. The use of the word "Fundamental" in the Fund's name reflects the fact that, in identifying the common stocks, the Index Provider uses fundamental measures of company size, rather than market capitalization (company share price multiplied by number of shares outstanding). The Index Provider uses the following fundamental measures to include common stocks in the Underlying Index: book value, income, sales and dividends. It then calculates a composite fundamental weight for each common stock by equally weighting the above four fundamental measures. The Index Provider then ranks each common stock by its fundamental weight and, based on this ranking, divides the common stocks into three size groups: "large," "mid" and "small." The common stocks it ranks in the top 70% of the eligible universe by fundamental weight comprise the "large" size group, the next 20% comprise the "mid" size group, and the final 10% comprise the "small" size group. The Index Provider further divides the "mid" size group into "growth," "core" or "value" subsets based on the Fundamental Index® methodology style score, which uses a combination of fundamental growth rates and fundamental valuation ratios. The Underlying Index is composed only of those common stocks that the Index Provider classifies as both "mid" and "core." The Fund generally will invest at least 80% of its total assets in common stocks of "fundamentally mid" companies. The Fund considers "fundamentally mid" companies to be those companies that comprise the Underlying Index. The use of the word "Pure" in the Fund's name reflects that, in selecting securities for the Underlying Index, the Index Provider includes only those securities that it has classified as "core." Although "core" funds also could include some stocks that, based on their classification, would be considered "growth" or "value," the Underlying Index contains only those stocks that the Index Provider classifies as pure "core" stocks. The Fund generally will invest in all of the securities comprising its Underlying Index in proportion to their weightings in the Underlying Index. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.

The returns on "core" securities may or may not move in tandem with the returns on other styles of investing or the overall stock market. Thus, the value of the Fund's investments will vary and at times may be lower or higher than that of other types of investments. "Fundamentally Mid" Company Risk. Investing in common stocks of "fundamentally mid" companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies' common stocks may be more volatile and less liquid than those of more established companies. These common stocks may have returns that vary, sometimes significantly, from the overall stock market. Often "fundamentally mid" companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. REIT Risk. Although the Fund will not invest in real estate directly, the REITs in which the Fund invests are subject to risks inherent in the direct ownership of real estate. These risks include, but are not limited to, a possible lack of mortgage funds and associated interest rate risks, overbuilding, property vacancies, increases in property taxes and operating expenses, changes in zoning laws, losses due to environmental damages and changes in neighborhood values and appeal to purchasers. Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Index may be comprised of issuers in a single industry or sector of the economy. If the Fund is focused in an industry or sector, it may present more risks than if it were diversified broadly over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries or the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Index resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the Federal Deposit insurance Corporation or any other government agency.

[1] Prior to June 16, 2011, the Fund sought to replicate, before fees and expenses, the performance of an index called the "Dynamic Mid Cap IntellidexSM Index." "1 Year" and "Since Inception" performance for the RAFI® Fundamental Mid Core Index is not available because the Index did not commence calculation and publication until April 15, 2011.

[2] Invesco PowerShares Capital Management LLC (the "Adviser") has agreed to waive fees and/or pay Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, brokerage commissions and other trading expenses, offering costs, taxes and extraordinary expenses) from exceeding 0.39% of the Fund's average daily net assets per year (the "Expense Cap") until at least August 31, 2012, and neither the Adviser nor the Fund can discontinue the agreement prior to its expiration. The expenses borne by the Adviser are subject to recapture by the Adviser for up to three years from the date the fee or expense was borne by the Adviser, but no recapture payment will be made by the Fund if it would result in the Fund exceeding its Expense Cap.

PowerShares Dividend Achievers Portfolio (Prospectus Summary) | PowerShares Dividend Achievers Portfolio

PowerShares Dividend AchieversTM Portfolio

Investment Objective

The PowerShares Dividend AchieversTM Portfolio (the "Fund") seeks investment
results that generally correspond (before fees and expenses) to the price and
yield of the Broad Dividend AchieversTM Index (the "Underlying Index").

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors may pay brokerage commissions on their
purchases and sales of Shares, which are not reflected in the table or the
example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		PowerShares Dividend Achievers Portfolio
Management Fees		0.40%
Other Expenses		0.21%
Total Annual Fund Operating Expenses		0.61%
Fee Waivers and Expense Assumption	[1]	0.01%
Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption	[1]	0.60%

Example

This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. This example assumes that you invest
$10,000 in the Fund for the time periods indicated and then sell all of your
Shares at the end of those periods. The example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. The cost under the one year example is equal to the Total
Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the
first year and the Total Annual Fund Operating Expenses thereafter. This example
does not include the brokerage commissions that investors may pay to buy and sell
Shares of the Fund.

Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Expense Example (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
PowerShares Dividend Achievers Portfolio	61	194	339	761

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover rate was 11% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 80% of its total assets in common stocks
of companies that have raised their annual regular cash dividend payments for at
least each of the last ten fiscal years. The Fund generally will invest at least
90% of its total assets in dividend-paying common stocks that comprise the
Underlying Index. Strictly in accordance with its existing guidelines and
mandated procedures, Mergent®, Inc. ("Mergent" or the "Index Provider") includes
stock in the Underlying Index pursuant to a proprietary selection methodology.
As of June 30, 2011, the Underlying Index was composed of stocks of
approximately 190 companies with a market capitalization range of between
approximately $289 million and $400 million. To qualify for the universe of
"Dividend AchieversTM," an issuer must have increased its annual regular cash
dividend payments for each of its last ten fiscal years.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying Index
reflects a concentration in that industry or group of industries. The Fund will
not otherwise concentrate its investments in securities of issuers in any one
industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Dividend Paying Security Risk. Securities that pay high dividends as a group can
fall out of favor with the market, causing such companies to underperform
companies that do not pay high dividends. Also changes in the dividend policies
of the companies in the Underlying Index and the capital resources available for
such companies' dividend payments may affect the Fund.

Market Risk. Securities in the Underlying Index are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Index.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets, and disruption in the creation/redemption process of the
Fund. Any of these factors may lead to the Shares trading at a premium or
discount to the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or debt
instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Index may be
composed of issuers in a single industry or sector of the economy. If the Fund
is focused in an industry or sector, it may present more risks than if it were
diversified broadly over numerous industries and sectors of the economy. At
times, such industry or group of industries may be out of favor and underperform
other industries or the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Index for a number of reasons. For example, the Fund incurs operating
expenses not applicable to the Underlying Index, and incurs costs in buying and
selling securities, especially when rebalancing the Fund's securities holdings
to reflect changes in the composition of the Underlying Index. In addition, the
performance of the Fund and the Underlying Index may vary due to asset valuation
differences and differences between the Fund's portfolio and the Underlying
Index resulting from legal restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Index.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Index, even if that
security generally is underperforming.

Small and Medium Capitalization Company Risk. Investing in securities of small
and medium capitalization companies involves greater risk than customarily is
associated with investing in larger, more established companies. These
companies' securities may be more volatile and less liquid than those of more
established companies. These securities may have returns that vary, sometimes
significantly, from the overall securities market. Often small and medium
capitalization companies and the industries in which they focus are still
evolving and, as a result, they may be more sensitive to changing market
conditions.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC
or any other government agency.

PowerShares Dynamic Oil & Gas Services Portfolio	64	204	356	797

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover rate was 39% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 80% of its total assets in common stocks
of companies that assist in the production, processing and distribution of oil
and gas. The Fund generally will invest at least 90% of its total assets in
common stocks that comprise the Underlying Intellidex. As of June 30, 2011, the
Underlying Intellidex was composed of stocks of 30 U.S. companies that assist in
the production, processing and distribution of oil and gas. The Underlying
Intellidex may include companies that are engaged in the drilling of oil and gas
wells; manufacturing oil and gas field machinery and equipment; or providing
services to the oil and gas industry, such as well analysis, platform and
pipeline engineering and construction, logistics and transportation services,
oil and gas well emergency management and geophysical data acquisition and
processing. Strictly in accordance with its existing guidelines and mandated
procedures, the Intellidex Provider includes stocks principally on the basis of
their capital appreciation potential that it identifies pursuant to a
proprietary Intellidex methodology. As of June 30, 2011, the Underlying
Intellidex included common stocks of companies with a market capitalization
range of between approximately $463 million and $117 billion.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying
Intellidex reflects a concentration in that industry or group of industries. The
Fund will not otherwise concentrate its investments in securities of issuers in
any one industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Oil and Gas Services Industry Concentration Risk. The profitability of companies
in the oil and gas services industry may be affected adversely by changes in
worldwide energy prices, exploration and production spending. Changes in
government regulation, economic conditions, government regulation and events in
the regions that the companies operate (e.g., expropriation, nationalization,
confiscation of assets and property or the imposition of restrictions on foreign
investments and repatriation of capital, military coups, social unrest, violence
or labor unrest, and terrorism and natural disasters) also affect companies in
this industry. In addition, these companies are at risk for environmental damage
claims. Companies in this industry could be adversely affected by commodity
price volatility, changes in exchange rates, interest rates, imposition of import
controls, increased competition, depletion of resources, development of alternative
energy sources, energy conservation efforts, technological developments and labor
relations. Companies in the oil and gas services industry may have significant
capital investments in, or engage in transactions involving, emerging market
countries, which may heighten these risks.

Market Risk. Securities in the Underlying Intellidex are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Intellidex.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets, and disruption in the creation/redemption process of the
Fund. Any of these factors may lead to the Shares trading at a premium or
discount to the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or debt
instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Intellidex is
comprised of issuers in a single industry or sector of the economy. By focusing
in an industry or sector, the Fund faces more risks than if it were diversified
broadly over numerous industries and sectors of the economy. At times, such
industry or group of industries may be out of favor and underperform other
industries or the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Intellidex for a number of reasons. For example, the Fund incurs
operating expenses not applicable to the Underlying Intellidex, and incurs costs
in buying and selling securities, especially when rebalancing the Fund's
securities holdings to reflect changes in the composition of the Underlying
Intellidex. In addition, the performance of the Fund and the Underlying
Intellidex may vary due to asset valuation differences and differences between
the Fund's portfolio and the Underlying Intellidex resulting from legal
restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Intellidex.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Intellidex, even if that
security generally is underperforming.

Small and Medium Capitalization Company Risk. Investing in securities of small
and medium capitalization companies involves greater risk than customarily is
associated with investing in larger, more established companies. These
companies' securities may be more volatile and less liquid than those of more
established companies. These securities may have returns that vary, sometimes
significantly, from the overall securities market. Often small and medium
capitalization companies and the industries in which they focus are still
evolving and, as a result, they may be more sensitive to changing market conditions.

Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater
portion of its assets in securities of individual issuers than a diversified
fund. As a result, changes in the market value of a single investment could
cause greater fluctuations in Share price than would occur in a diversified
fund. This may increase the Fund's volatility and cause the performance of a
relatively small number of issuers to have a greater impact on the Fund's
performance.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC
or any other government agency.

Performance

The bar chart below shows how the Fund has performed. The table below the bar
chart shows the Fund's average annual total returns (before and after taxes).
The bar chart and table provide an indication of the risks of investing in the
Fund by showing how the Fund's total return has varied from year to year and by
showing how the Fund's average annual total returns compared with a broad
measure of market performance. The Fund's performance reflects fee waivers, if
any, absent which, performance would have been lower. Although the information
shown in the bar chart and the table gives you some idea of the risks involved
in investing in the Fund, the Fund's past performance (before and after taxes)
is not necessarily indicative of how the Fund will perform in the future.

Investment Strategy, Heading	rr_StrategyHeading	Principal Investment Strategies
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 90% of its total assets in securities that comprise the Underlying Index. The Underlying Index is designed to provide exposure to the constituents of the S&P 500® Index that S&P Quality Rankings identifies as high quality stocks. Quality Rankings reflect the long-term growth and stability of a company's earnings and dividends. Stocks with a Quality Ranking of A- or above comprise the Underlying Index. Strictly in accordance with its existing guidelines and mandated procedures, S&P Quality Rankings assigns stocks Quality Rank Scores from 1 to 3, with a higher Quality Rank leading to a higher Quality Rank Score. As of June 30, 2011, the Underlying Index consisted of common stocks of approximately 125 companies with a market capitalization range of between approximately $2 billion and $400 billion. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.

Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Index may be composed of issuers in a single industry or sector of the economy. If the Fund is focused in an industry or sector, it may present more risks than if it were broadly diversified over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries of the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Index resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming. Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater portion of assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in share price than would occur in a diversified fund. This may increase the Fund's volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund's performance. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective.

Investment Strategy, Heading	rr_StrategyHeading	Principal Investment Strategies
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 90% of its total assets in common stocks that comprise the Underlying Index. Strictly in accordance with its existing guidelines and mandated procedures, Mergent®, Inc. ("Mergent" or the "Index Provider") includes stocks in the Underlying Index pursuant to a proprietary selection methodology. As of June 30, 2011, the Underlying Index was composed of stocks of approximately 143 companies with a market capitalization range of between approximately $165 million and $207 billion. To qualify for the universe of "BuyBack AchieversTM," an issuer must have repurchased at least 5% of its outstanding shares during the trailing 12 months. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.

The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Index may be composed of issuers in a single industry or sector of the economy. If the Fund is focused in an industry or sector, it may present more risks than if it were diversified broadly over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries or the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Index resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming. Small and Medium Capitalization Company Risk. Investing in securities of small and medium capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Often small and medium capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund's volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund's performance. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC or any other government agency.

[1] Invesco PowerShares Capital Management LLC (the "Adviser") has agreed to waive fees and/or pay Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, brokerage commissions and other trading expenses, sub-licensing fees, offering costs, taxes and extraordinary expenses) from exceeding 0.60% of the Fund's average daily net assets per year (the "Expense Cap") until at least August 31, 2012, and neither the Adviser nor the Fund can discontinue the agreement prior to its expiration. The expenses borne by the Adviser are subject to recapture by the Adviser for up to three years from the date the fee or expense was borne by the Adviser; but no recapture payment will be made by the Fund if it would result in the Fund exceeding its Expense Cap.

Investment Strategy, Heading	rr_StrategyHeading	Principal Investment Strategies
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 80% of its total assets in common stocks of micro capitalization companies. Zacks Investment Research ("Zacks" or "Index Provider") considers a company to be a micro capitalization company if it falls within the Underlying Index model, as described below. The Fund generally will invest at least 90% of its total assets in common stocks that comprise the Underlying Index. As of June 30, 2011, the Underlying Index was composed of approximately 400 U.S. stocks that, strictly in accordance with its existing guidelines and mandated procedures, Zack's includes from a universe of 7,000 domestic companies. For the purpose of constituent selection, the micro capitalization subset is defined relative to the entire investable universe of stocks, with the upper threshold equal to 0.15% of the capitalization of the largest capitalization domestic company at the time of selection (currently approximately $600 million) and a minimum capitalization of approximately 0.015% of the largest capitalization domestic company (currently approximately $60 million). Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.

The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. Micro Capitalization Company Risk. Investments in the securities of micro capitalization companies involve substantially greater risks of loss and price fluctuations than stocks with larger capitalization. Micro capitalization companies carry additional risks because their earnings and revenues tend to be less predictable (and some companies may experience significant losses), their share prices tend to be more volatile and their markets less liquid than companies with larger market capitalizations. Micro capitalization companies may be newly formed or in the early stages of development, with limited product lines, markets or financial resources, and they may lack management depth. In addition, less public information may be available about these companies. The shares of micro capitalization companies tend to trade less frequently than those of larger, more established companies, which can adversely affect the pricing of these securities and the future ability to sell these securities. Also, the Fund may take a long time before it realizes a gain, if any, on an investment in a micro capitalization company. Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index. Market Trading Risk. The Fund faces market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Index may be composed of issuers in a single industry or sector of the economy. If the Fund is focused in an industry or sector, it may present more risks than if it were diversified broadly over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries or the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Index resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Intellidex. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Intellidex, even if that security generally is underperforming. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC or any other government agency.

[1] Acquired Fund Fees and Expenses are indirect fees and expenses that the Fund incurs from investing in the shares of other investment companies. Please note that the amount of Total Annual Fund Operating Expenses shown in the above table may differ from the ratio of expenses prior to waivers and/or recapture to average net assets included in the "Financial Highlights" section of this Prospectus, which reflects the operating expenses of the Fund and does not include indirect expenses such as Acquired Fund Fees and Expenses.

[2] Invesco PowerShares Capital Management LLC (the "Adviser") has agreed to waive fees and/or pay Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, brokerage commissions and other trading expenses, sub-licensing fees, offering costs, taxes and extraordinary expenses) from exceeding 0.60% of the Fund's average daily net assets per year (the "Expense Cap") until at least August 31, 2012, and neither the Adviser nor the Fund can discontinue the agreement prior to its expiration. The expenses borne by the Adviser are subject to recapture by the Adviser for up to three years from the date the fee or expense was borne by the Adviser, but no recapture payment will be made by the Fund if it would result in the Fund exceeding its Expense Cap.

PowerShares Dynamic Semiconductors Portfolio (Prospectus Summary) | PowerShares Dynamic Semiconductors Portfolio

PowerShares Dynamic Semiconductors Portfolio

Investment Objective

The PowerShares Dynamic Semiconductors Portfolio (the "Fund") seeks investment
results that generally correspond (before fees and expenses) to the price and
yield of the Dynamic Semiconductors IntellidexSM Index (the "Underlying
Intellidex").

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors may pay brokerage commissions on their
purchases and sales of Shares, which are not reflected in the table or the
example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		PowerShares Dynamic Semiconductors Portfolio
Management Fees		0.50%
Other Expenses		0.47%
Total Annual Fund Operating Expenses		0.97%
Fee Waivers and Expense Assumption	[1]	0.34%
Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption	[1]	0.63%

Example

This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. This example assumes that you invest
$10,000 in the Fund for the time periods indicated and then sell all of your
Shares at the end of those periods. The example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. The cost under the one year example is equal to the Total
Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the
first year and the Total Annual Fund Operating Expenses thereafter. This example
does not include the brokerage commissions that investors may pay to buy and
sell Shares of the Fund.

Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

PowerShares Dynamic Semiconductors Portfolio	64	275	503	1,159

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover rate was 64% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 80% of its total assets in common stocks
of semiconductor companies. The Fund generally will invest at least 90% of its
total assets in common stocks that comprise the Underlying Intellidex. As of
June 30, 2011, the Underlying Intellidex was composed of stocks of 30 U.S.
semiconductors companies. These companies are engaged principally in the
manufacture of semiconductors. These companies may include, for example,
companies involved in all aspects of the electronics business and in new
technologies or specialty areas, including advanced design and manufacturing
technologies, and lasers and electro-optics. Strictly in accordance with its
existing guidelines and mandated procedures, the Intellidex Provider includes
stocks principally on the basis of their capital appreciation potential that it
identifies pursuant to a proprietary Intellidex methodology. As of June 30,
2011, the Underlying Intellidex included common stocks of companies with a
market capitalization range of between approximately $341 million and $95
billion.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying
Intellidex reflects a concentration in that industry or group of industries. The
Fund will not otherwise concentrate its investments in securities of issuers in
any one industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Semiconductors Industry Concentration Risk. Competitive pressures, intense
competition, aggressive pricing, technological developments, changing demand,
research and development costs, availability and price of components and product
obsolescence can significantly affect the semiconductors industry.

Market Risk. Securities in the Underlying Intellidex are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Intellidex.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets, and disruption in the creation/redemption process of the
Fund. Any of these factors may lead to the Shares trading at a premium or discount
to the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or debt
instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Intellidex is
comprised of issuers in a single industry or sector of the economy. By focusing
in an industry or sector, the Fund faces more risks than if it were diversified
broadly over numerous industries and sectors of the economy. At times, such
industry or group of industries may be out of favor and underperform other
industries or the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Intellidex for a number of reasons. For example, the Fund incurs
operating expenses not applicable to the Underlying Intellidex, and incurs costs
in buying and selling securities, especially when rebalancing the Fund's
securities holdings to reflect changes in the composition of the Underlying
Intellidex. In addition, the performance of the Fund and the Underlying
Intellidex may vary due to asset valuation differences and differences between
the Fund's portfolio and the Underlying Intellidex resulting from legal
restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Intellidex.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Intellidex, even if that
security generally is underperforming.

Small and Medium Capitalization Company Risk. Investing in securities of small
and medium capitalization companies involves greater risk than customarily is
associated with investing in larger, more established companies. These
companies' securities may be more volatile and less liquid than those of more
established companies. These securities may have returns that vary, sometimes
significantly, from the overall securities market. Often small and medium
capitalization companies and the industries in which they focus are still
evolving and, as a result, they may be more sensitive to changing market
conditions.

Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater
portion of its assets in securities of individual issuers than a diversified
fund. As a result, changes in the market value of a single investment could
cause greater fluctuations in Share price than would occur in a diversified
fund. This may increase the Fund's volatility and cause the performance of a
relatively small number of issuers to have a greater impact on the Fund's
performance.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC
or any other government agency.

Performance

The bar chart below shows how the Fund has performed. The table below the bar
chart shows the Fund's average annual total returns (before and after taxes).
The bar chart and table provide an indication of the risks of investing in the
Fund by showing how the Fund's total return has varied from year to year and by
showing how the Fund's average annual total returns compared with a broad
measure of market performance. The Fund's performance reflects fee waivers, if
any, absent which, performance would have been lower. Although the information
shown in the bar chart and the table gives you some idea of the risks involved
in investing in the Fund, the Fund's past performance (before and after taxes)
is not necessarily indicative of how the Fund will perform in the future.

Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 80% of its total assets in common stocks of nanotechnology companies. A nanotechnology company focuses on the development and use of devices that are only a few nanometers in size. The Fund generally will invest at least 90% of its total assets in common stocks that comprise the Underlying Index. The Underlying Index is a modified equal dollar weighted index that, as of June 30, 2011, was composed of stocks of approximately 21 publicly traded companies in the nanotechnology field. Strictly in accordance with its existing guidelines and mandated procedures, Lux Research, Inc ("Lux" or the "Index Provider") includes companies in the nanotechnology field that are involved with funding nanotechnology development, developing nanotechnology applications, manufacturing goods that incorporate those applications and/or supplying tools and instrumentation to nanotechnology researchers. As of June 30, 2011, the Underlying Index included common stocks of companies with a market capitalization range of between approximately $80 million and $205 billion. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries.

Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. Nanotechnology Industry Concentration Risk. Small technology companies are especially risky. These companies may be less experienced, with limited product lines, markets or financial resources. Consequently, these companies are subject to scientific, technological and commercialization risks. These securities have a significantly greater risk of loss than traditional investment securities due to the speculative nature of these investments. Technology companies generally are subject to the risk of rapidly changing technologies, a limited product life span due to the frequent introduction of new or improved products, as well as cyclical market patterns and evolving industry standards. Technology companies also face the risk of losing patent, copyright and trademark protections. Sampling Risk. The Fund's use of a representative sampling approach will result in its holding a smaller number of securities than are in the Underlying Index. As a result, an adverse development respecting an issuer of securities held by the Fund could result in a greater decline in NAV than would be the case if the Fund held all of the securities in the Underlying Index. To the extent the assets in the Fund are smaller, these risks will be greater. Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Index is comprised of issuers in a single industry or sector of the economy. By focusing in an industry or sector, the Fund faces more risks than if it were diversified broadly over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries or the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Index resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming. Small Capitalization Company Risk. Investing in securities of small capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Often small capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund's volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund's performance. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective.

[1] Acquired Fund Fees and Expenses are indirect fees and expenses that the Fund incurs from investing in the shares of other investment companies. Please note that the amount of Total Annual Fund Operating Expenses shown in the above table may differ from the ratio of expenses prior to waivers and/or recapture to average net assets included in the "Financial Highlights" section of this Prospectus, which reflects the operating expenses of the Fund and does not include indirect expenses such as Acquired Fund Fees and Expenses.

[2] Invesco PowerShares Capital Management LLC (the "Adviser") has agreed to waive fees and/or pay Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, brokerage commissions and other trading expenses, sub-licensing fees, offering costs, taxes and extraordinary expenses) from exceeding 0.60% of the Fund's average daily net assets per year (the "Expense Cap") until at least August 31, 2012, and neither the Adviser nor the Fund can discontinue the agreement prior to its expiration. The expenses borne by the Adviser are subject to recapture by the Adviser for up to three years from the date the fee or expense was borne by the Adviser, but no recapture payment will be made by the Fund if it would result in the Fund exceeding its Expense Cap.

Investment Strategy, Heading	rr_StrategyHeading	Principal Investment Strategies
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 80% of its total assets in common stocks of companies that assist in the production, processing and distribution of oil and gas. The Fund generally will invest at least 90% of its total assets in common stocks that comprise the Underlying Intellidex. As of June 30, 2011, the Underlying Intellidex was composed of stocks of 30 U.S. companies that assist in the production, processing and distribution of oil and gas. The Underlying Intellidex may include companies that are engaged in the drilling of oil and gas wells; manufacturing oil and gas field machinery and equipment; or providing services to the oil and gas industry, such as well analysis, platform and pipeline engineering and construction, logistics and transportation services, oil and gas well emergency management and geophysical data acquisition and processing. Strictly in accordance with its existing guidelines and mandated procedures, the Intellidex Provider includes stocks principally on the basis of their capital appreciation potential that it identifies pursuant to a proprietary Intellidex methodology. As of June 30, 2011, the Underlying Intellidex included common stocks of companies with a market capitalization range of between approximately $463 million and $117 billion. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Intellidex reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.

The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. Oil and Gas Services Industry Concentration Risk. The profitability of companies in the oil and gas services industry may be affected adversely by changes in worldwide energy prices, exploration and production spending. Changes in government regulation, economic conditions, government regulation and events in the regions that the companies operate (e.g., expropriation, nationalization, confiscation of assets and property or the imposition of restrictions on foreign investments and repatriation of capital, military coups, social unrest, violence or labor unrest, and terrorism and natural disasters) also affect companies in this industry. In addition, these companies are at risk for environmental damage claims. Companies in this industry could be adversely affected by commodity price volatility, changes in exchange rates, interest rates, imposition of import controls, increased competition, depletion of resources, development of alternative energy sources, energy conservation efforts, technological developments and labor relations. Companies in the oil and gas services industry may have significant capital investments in, or engage in transactions involving, emerging market countries, which may heighten these risks. Market Risk. Securities in the Underlying Intellidex are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Intellidex. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Intellidex is comprised of issuers in a single industry or sector of the economy. By focusing in an industry or sector, the Fund faces more risks than if it were diversified broadly over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries or the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Intellidex for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Intellidex, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Intellidex. In addition, the performance of the Fund and the Underlying Intellidex may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Intellidex resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Intellidex. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Intellidex, even if that security generally is underperforming. Small and Medium Capitalization Company Risk. Investing in securities of small and medium capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Often small and medium capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund's volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund's performance. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC or any other government agency.

PowerShares Fundamental Pure Small Growth Portfolio (Prospectus Summary) | PowerShares Fundamental Pure Small Growth Portfolio

PowerShares Fundamental Pure Small Growth Portfolio

Investment Objective

The PowerShares Fundamental Pure Small Growth Portfolio (the "Fund") seeks
investment results that generally correspond (before fees and expenses) to the
price and yield of the RAFI® Fundamental Small Growth Index (the "Underlying
Index").

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors may pay brokerage commissions on their
purchases and sales of Shares, which are not reflected in the table or the
example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		PowerShares Fundamental Pure Small Growth Portfolio
Management Fees		0.29%
Other Expenses		0.64%
Total Annual Fund Operating Expenses		0.93%
Fee Waivers and Expense Assumption	[1]	0.30%
Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption	[1]	0.63%

Example

This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. This example assumes that you invest
$10,000 in the Fund for the time periods indicated and then sell all of your
Shares at the end of those periods. The example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. The cost under the one year example is equal to the Total
Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the
first year and the Total Annual Fund Operating Expenses thereafter. This example
does not include the brokerage commissions that investors may pay to buy and
sell Shares of the Fund.

Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Expense Example (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
PowerShares Fundamental Pure Small Growth Portfolio	64	266	485	1,116

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Shares are held in a taxable account. These costs, which are
not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the fiscal year ended April 30, 2011, the
Fund's portfolio turnover rate was 57% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 90% of its total assets in the component
securities that comprise the Underlying Index. The Underlying Index is comprised
of common stocks of "small growth" U.S. companies (including real estate
investment trusts ("REITs")) that Research Affiliates, LLC ("RAFI Affiliates" or
the "Index Provider") classifies based on its Fundamental Index® methodology.
Strictly in accordance with its existing guidelines and mandated procedures, the
Index Provider identifies the common stocks for inclusion in the Underlying
Index from a universe of the 2,500 largest U.S. companies. The use of the word
"Fundamental" in the Fund's name reflects the fact that, in identifying the
common stocks, the Index Provider uses fundamental measures of company size,
rather than market capitalization (company share price multiplied by number of
shares outstanding). The Index Provider uses the following fundamental measures
to include common stocks in the Underlying Index: book value, income, sales and
dividends. It then calculates a composite fundamental weight for each common
stock by equally weighting the above four fundamental measures. The Index
Provider then ranks each common stock by its fundamental weight and, based on
this ranking, divides the common stocks into three size groups: "large," "mid"
and "small." The common stocks it ranks in the top 70% of the eligible universe
by fundamental weight comprise the "large" size group, the next 20% comprise the
"mid" size group, and the final 10% comprise the "small" size group. The Index
Provider further divides the "small" size group into "growth," "core" or "value"
subsets based on the Fundamental Index® methodology style score, which uses a
combination of fundamental growth rates and fundamental valuation ratios. The
Underlying Index is composed only of those common stocks that the Index Provider
classifies as both "small" and "growth." The Fund generally will invest at least
80% of its total assets in common stocks of "fundamentally small" companies. The
Fund considers "fundamentally small" companies to be those companies that
comprise the Underlying Index.

The use of the word "Pure" in the Fund's name reflects that, in selecting
securities for the Underlying Index, the Index Provider includes only those
securities that it has classified as "growth." Although "growth" funds also
could include some stocks that, based on their classification, would be
considered "core" or "value," the Underlying Index contains only those stocks
that the Index Provider classifies as pure "growth" stocks. The Fund generally
will invest in all of the securities comprising its Underlying Index in
proportion to their weightings in the Underlying Index.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying Index
reflects a concentration in that industry or group of industries. The Fund will
not otherwise concentrate its investments in securities of issuers in any one
industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

"Fundamentally Small" Company Risk. Investing in common stocks of "fundamentally
small" companies involves greater risk than customarily is associated with
investing in larger, more established companies. These companies' common stocks
may be more volatile and less liquid than those of more established companies.
These common stocks may have returns that vary, sometimes significantly, from
the overall stock market. Often "fundamentally small" companies and the
industries in which they focus are still evolving and. As a result, they may be
more sensitive to changing market conditions.

Growth Risk. The market values of "growth" securities may be more volatile than
other types of investments. The returns on "growth" securities may or may not
move in tandem with the returns on other styles of investing or the overall
stock market. Thus, the value of the Fund's investments will vary and at times
may be lower or higher than that of other types of investments.

REIT Risk. Although the Fund will not invest in real estate directly, the REITs
in which the Fund invests are subject to risks inherent in the direct ownership
of real estate. These risks include, but are not limited to, a possible lack of
mortgage funds and associated interest rate risks, overbuilding, property
vacancies, increases in property taxes and operating expenses, changes in zoning
laws, losses due to environmental damages and changes in neighborhood values and
appeal to purchasers.

Market Risk. Securities in the Underlying Index are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Index.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets, and disruption in the creation/redemption process of the
Fund. Any of these factors may lead to the Shares trading at a premium or
discount to the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or debt
instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Index may be
comprised of issuers in a single industry or sector of the economy. If the Fund
is focused in an industry or sector, it may present more risks than if it were
diversified broadly over numerous industries and sectors of the economy. At
times, such industry or group of industries may be out of favor and underperform
other industries or the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Index for a number of reasons. For example, the Fund incurs operating
expenses not applicable to the Underlying Index, and incurs costs in buying and
selling securities, especially when rebalancing the Fund's securities holdings
to reflect changes in the composition of the Underlying Index. In addition, the
performance of the Fund and the Underlying Index may vary due to asset valuation
differences and differences between the Fund's portfolio and the Underlying
Index resulting from legal restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Index.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Index, even if that
security generally is underperforming.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the
Federal Deposit Insurance Corporation or any other government agency.

Performance

The bar chart below shows how the Fund has performed. The table below the bar
chart shows the Fund's average annual total returns (before and after taxes).
The bar chart and table provide an indication of the risks of investing in the
Fund by showing how the Fund's total return has varied from year to year and by
showing how the Fund's average annual total returns compared with a broad
measure of market performance. The Fund's performance reflects fee waivers, if
any, absent which, performance would have been lower. Although the information
shown in the bar chart and the table gives you some idea of the risks involved
in investing in the Fund, the Fund's past performance (before and after taxes)
is not necessarily indicative of how the Fund will perform in the future.

situation and may differ from those shown, and after-tax returns shown are not
relevant to investors who hold Shares through tax-deferred arrangements, such as
401(k) plans or individual retirement accounts. In the event of negative
performance displayed in the table below, the Fund's returns after taxes on
distributions and sale of Fund Shares are calculated assuming that an investor
has sufficient capital gains of the same character from other investments to
offset any capital losses from the sale of Fund Shares so that the investor may
deduct the losses in full. As a result, the Fund's returns after taxes on
distributions and sale of Fund Shares may exceed the Fund's returns before taxes
and/or returns after taxes on distributions.

PowerShares Dynamic MagniQuant Portfolio (Prospectus Summary) | PowerShares Dynamic MagniQuant Portfolio

PowerShares Dynamic MagniQuant Portfolio

Investment Objective

The PowerShares Dynamic MagniQuant Portfolio (the "Fund") seeks investment
results that generally correspond (before fees and expenses) to the price and
yield of the Dynamic Top 200 IntellidexSM Index (the "Underlying Intellidex").

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors may pay brokerage commissions on their
purchases and sales of Shares, which are not reflected in the table or the
example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		PowerShares Dynamic MagniQuant Portfolio
Management Fees		0.50%
Other Expenses		0.58%
Total Annual Fund Operating Expenses		1.08%
Fee Waivers and Expense Assumption	[1]	0.43%
Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption	[1]	0.65%

Example

This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. This example assumes that you invest
$10,000 in the Fund for the time periods indicated and then sell all of your
Shares at the end of those periods. The example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. The cost under the one year example is equal to the Total
Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the
first year and the Total Annual Fund Operating Expenses thereafter. This example
does not include the brokerage commissions that investors may pay to buy and
sell Shares of the Fund.

Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Expense Example (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
PowerShares Dynamic MagniQuant Portfolio	66	301	554	1,278

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover rate was 93% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 90% of its total assets in common stocks
that comprise the Underlying Intellidex. As of June 30, 2011, the Underlying
Intellidex was composed of approximately 200 U.S. stocks of companies that NYSE
Arca, Inc. ("NYSE Arca" or the "Intellidex Provider"), strictly in accordance
with its existing guidelines and mandated procedures, included pursuant to a
proprietary selection methodology. As of June 30, 2011, the Underlying
Intellidex included common stocks of companies with a market capitalization
range of between approximately $324 million and $396 billion.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying
Intellidex reflects a concentration in that industry or group of industries. The
Fund will not otherwise concentrate its investments in securities of issuers in
any one industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Market Risk. Securities in the Underlying Intellidex are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Intellidex.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for Shares, losses from trading in secondary
markets, and disruption in the creation/redemption process of the Fund. Any of
these factors may lead to Shares trading at a premium or discount to the Fund's
net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
of an issuer may be particularly sensitive to general movements in the stock
market; or a drop in the stock market may depress the price of most or all of the
common stocks and other equity securities the Fund holds. In addition, common stock
of an issuer in the Fund's portfolio may decline in price if the issuer fails to
make anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a company's
capital structure, in terms of priority to corporate income, and therefore will be
subject to greater dividend risk than preferred stocks or debt instruments of such
issuers.

Concentration Risk. A significant percentage of the Underlying Intellidex may be
composed of issuers in a single industry or sector of the economy. If the Fund
is focused in an industry or sector, it may present more risks than if it were
broadly diversified over numerous industries and sectors of the economy. At
times, such industry or group of industries may be out of favor and underperform
other industries of the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Intellidex for a number of reasons. For example, the Fund incurs
operating expenses not applicable to the Underlying Intellidex, and incurs costs
in buying and selling securities, especially when rebalancing the Fund's
securities holdings to reflect changes in the composition of the Underlying
Intellidex. In addition, the performance of the Fund and the Underlying
Intellidex may vary due to asset valuation differences and differences between
the Fund's portfolio and the Underlying Intellidex resulting from legal
restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Intellidex.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Intellidex, even if that
security generally is underperforming.

Small and Medium Capitalization Company Risk. Investing in securities of small
and medium capitalization companies involves greater risk than customarily is
associated with investing in larger, more established companies. These
companies' securities may be more volatile and less liquid than those of more
established companies. These securities may have returns that vary, sometimes
significantly, from the overall securities market. Often small and medium
capitalization companies and the industries in which they focus are still
evolving and, as a result, they may be more sensitive to changing market
conditions.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC
or any other government agency.

PowerShares Cleantech Portfolio	68	230	405	912

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover was 24% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 80% of its total assets in stocks of
cleantech companies. The Fund generally will invest at least 90% of its total
assets in the securities that compose the Underlying Index and American
despositary receipts ("ADRs") based on the stocks in the Underlying Index. The
Fund anticipates that the majority of its investment will be in the securities
that compose the Underlying Index. The Underlying Index is a modified equally
weighted index currently composed of stocks of publicly-traded cleantech
companies and ADRs based on such stocks. Cleantech Indices LLC ("Cleantech" or
the "Index Provider") considers a company to be a cleantech company if it
derives at least 50% of its revenues or operating profits from cleantech
businesses. Cleantech businesses are those that provide knowledge-based products
(or services) that add economic value by reducing cost and raising productivity
and/or product performance, while reducing the consumption of resources and the
negative impact on the environment and public health. The Underlying Index
focuses on companies that are leaders in the innovation and commercial
deployment of cleantech products across a broad range of industries including,
but not limited to, alternative energy, energy efficiency and transmission, air
and water purification, advanced materials, eco-friendly agriculture,
transportation, manufacturing efficiency, recycling and pollution prevention.
Strictly in accordance with its existing guidelines and mandated procedures, the
Index Provider identifies the securities composing the Underlying Index, which,
as of June 30, 2011, included common stocks of approximately 70 companies with a
market capitalization range of between approximately $200 million and $120
billion.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying Index
reflects a concentration in that industry or group of industries. The Fund will
not otherwise concentrate its investments in securities of issuers in any one
industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Cleantech Sector Risk. There are risks in investing in the cleantech sector,
including the risks of focusing investments in the water, energy and
environmental sectors. Adverse developments in the water, energy and
environmental sectors may significantly affect the value of the Shares.
Companies involved in the water sector are subject to tax and price fluctuations
and competition. Securities of companies in the energy sector are subject
to swift price and supply fluctuations caused by events relating to international
politics, the success of project development and tax and other governmental
regulatory policies. Weak demand for the companies' products or services or
for energy products and services in general, as well as negative developments
in these other areas, may adversely affect the Fund's performance.

Foreign Investment Risk. Investments in the securities of non-U.S. issuers
involve risks beyond those associated with investments in U.S. securities. These
additional risks include greater market volatility, the availability of less
reliable financial information, higher transactional costs, taxation by foreign
governments, decreased market liquidity and political instability. As the Fund
will invest in securities denominated in foreign currencies, changes in currency
exchange rates may negatively impact the Fund's returns.

Market Risk. Securities in the Underlying Index are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Index.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets, and disruption in the creation/redemption process of the
Fund. Any of these factors may lead to the Shares trading at a premium or
discount to the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or debt
instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Index is
comprised of issuers in a single industry or sector of the economy. By focusing
in an industry or sector, the Fund faces more risks than if it were diversified
broadly over numerous industries and sectors of the economy. At times, such
industry or group of industries may be out of favor and underperform other
industries or the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Index for a number of reasons. For example, the Fund incurs operating
expenses not applicable to the Underlying Index, and incurs costs in buying and
selling securities, especially when rebalancing the Fund's securities holdings
to reflect changes in the composition of the Underlying Index. In addition, the
performance of the Fund and the Underlying Index may vary due to asset valuation
differences and differences between the Fund's portfolio and the Underlying
Index resulting from legal restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Index.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Index, even if that
security generally is underperforming.

Small and Medium Capitalization Company Risk. Investing in securities of small
and medium capitalization companies involves greater risk than customarily is
associated with investing in larger, more established companies. These
companies' securities may be more volatile and less liquid than those of more
established companies. These securities may have returns that vary, sometimes
significantly, from the overall securities market. Often small and medium
capitalization companies and the industries in which they focus are still
evolving and, as a result, they may be more sensitive to changing market
conditions.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the

PowerShares Zacks Micro Cap Portfolio

Investment Objective

The PowerShares Zacks Micro Cap Portfolio (the "Fund") seeks investment results
that generally correspond (before fees and expenses) to the price and yield of
the Zacks Micro Cap IndexTM (the "Underlying Index").

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors may pay brokerage commissions on their
purchases and sales of Shares, which are not reflected in the table or the
example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		PowerShares Zacks Micro Cap Portfolio
Management Fees		0.50%
Other Expenses		0.26%
Acquired Fund Fees and Expenses	[1]	0.09%
Total Annual Fund Operating Expenses		0.85%
Fee Waivers and Expense Assumption	[2]	0.15%
Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption	[2]	0.70%

Example

This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. This example assumes that you invest
$10,000 in the Fund for the time periods indicated and then sell all of your
Shares at the end of those periods. The example also assumes that your
investment has a 5% return each year
and that the Fund's operating expenses remain the same. The cost under the one
year example is equal to the Total Annual Fund Operating Expenses After Fee
Waivers and Expense Assumption in the first year and the Total Annual Fund
Operating Expenses thereafter. This example does not include the brokerage
commissions that investors may pay to buy and sell Shares of the Fund.

Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Expense Example (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
PowerShares Zacks Micro Cap Portfolio	72	256	457	1,035

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover rate was 61% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 80% of its total assets in common stocks
of micro capitalization companies. Zacks Investment Research ("Zacks" or "Index
Provider") considers a company to be a micro capitalization company if it falls
within the Underlying Index model, as described below. The Fund generally will
invest at least 90% of its total assets in common stocks that comprise the
Underlying Index. As of June 30, 2011, the Underlying Index was composed of
approximately 400 U.S. stocks that, strictly in accordance with its existing
guidelines and mandated procedures, Zack's includes from a universe of 7,000
domestic companies. For the purpose of constituent selection, the micro
capitalization subset is defined relative to the entire investable universe of
stocks, with the upper threshold equal to 0.15% of the capitalization of the
largest capitalization domestic company at the time of selection (currently
approximately $600 million) and a minimum capitalization of approximately 0.015%
of the largest capitalization domestic company (currently approximately $60
million).

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying Index
reflects a concentration in that industry or group of industries. The Fund will
not otherwise concentrate its investments in securities of issuers in any one
industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Micro Capitalization Company Risk. Investments in the securities of micro
capitalization companies involve substantially greater risks of loss and price
fluctuations than stocks with larger capitalization. Micro capitalization
companies carry additional risks because their earnings and revenues tend to be
less predictable (and some companies may experience significant losses), their
share prices tend to be more volatile and their markets less liquid than
companies with larger market capitalizations. Micro capitalization companies may
be newly formed
or in the early stages of development, with limited product lines, markets or
financial resources, and they may lack management depth. In addition, less
public information may be available about these companies. The shares of micro
capitalization companies tend to trade less frequently than those of larger,
more established companies, which can adversely affect the pricing of these
securities and the future ability to sell these securities. Also, the Fund may
take a long time before it realizes a gain, if any, on an investment in a micro
capitalization company.

Market Risk. Securities in the Underlying Index are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Index.

Market Trading Risk. The Fund faces market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets, and disruption in the creation/redemption process of the
Fund. Any of these factors may lead to the Shares trading at a premium or
discount to the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or debt
instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Index may be
composed of issuers in a single industry or sector of the economy. If the Fund
is focused in an industry or sector, it may present more risks than if it were
diversified broadly over numerous industries and sectors of the economy. At
times, such industry or group of industries may be out of favor and underperform
other industries or the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Index for a number of reasons. For example, the Fund incurs operating
expenses not applicable to the Underlying Index, and incurs costs in buying and
selling securities, especially when rebalancing the Fund's securities holdings
to reflect changes in the composition of the Underlying Index. In addition, the
performance of the Fund and the Underlying Index may vary due to asset valuation
differences and differences between the Fund's portfolio and the Underlying
Index resulting from legal restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Intellidex.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Intellidex, even if that
security generally is underperforming.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC
or any other government agency.

Performance

The bar chart below shows how the Fund has performed. The table below the bar
chart shows the Fund's average annual total returns (before and after taxes).
The bar chart and table provide an indication of the risks of investing in the
Fund by showing how the Fund's total return has varied from year to year and by
showing how the Fund's average annual total returns compared with a broad
measure of market performance. The Fund's performance reflects fee waivers, if
any, absent which, performance would have been lower. Although the information
shown in the bar chart and the table gives you some idea of the risks involved
in investing in the Fund, the Fund's past performance (before and after taxes)
is not necessarily indicative of how the Fund will perform in the future.
Updated performance information is available online at

The bar chart below shows how the Fund has performed.

Annual Total Returns-Calendar Years

The Fund's year-to-date total return for the six months ended June 30, 2011 was
(0.72)%.

        Best Quarter                    Worst Quarter
20.88% (2nd Quarter 2009)       (29.12)% (4th Quarter 2008)

After-tax returns in the table below are calculated using the historical highest
individual federal marginal income tax rates and do not reflect the impact of
state and local taxes. Actual after-tax returns depend on an investor's tax
situation and may differ from those shown, and after-tax returns shown are not
relevant to investors who hold Shares through tax-deferred arrangements, such as
401(k) plans or individual retirement accounts. In the event of negative
performance displayed in the table below, the Fund's returns after taxes on
distributions and sale of Fund Shares are calculated assuming that an investor
has sufficient capital gains of the same character from other investments to
offset any capital losses from the sale of Fund Shares so that the investor may
deduct the losses in full. As a result, the Fund's returns after taxes on
distributions and sale of Fund Shares may exceed the Fund's returns before taxes
and/or returns after taxes on distributions.

[1] Acquired Fund Fees and Expenses are indirect fees and expenses that the Fund incurs from investing in the shares of other investment companies. Please note that the amount of Total Annual Fund Operating Expenses shown in the above table may differ from the ratio of expenses prior to waivers and/or recapture to average net assets included in the "Financial Highlights" section of this Prospectus, which reflects the operating expenses of the Fund and does not include indirect expenses such as Acquired Fund Fees and Expenses.

[2] Invesco PowerShares Capital Management LLC (the "Adviser") has agreed to waive fees and/or pay Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, brokerage commissions and other trading expenses, sub-licensing fees, offering costs, taxes and extraordinary expenses) from exceeding 0.60% of the Fund's average daily net assets per year (the "Expense Cap") until at least August 31, 2012, and neither the Adviser nor the Fund can discontinue the agreement prior to its expiration. The expenses borne by the Adviser are subject to recapture by the Adviser for up to three years from the date the fee or expense was borne by the Adviser, but no recapture payment will be made by the Fund if it would result in the Fund exceeding its Expense Cap.

Investment Strategy, Heading	rr_StrategyHeading	Principal Investment Strategies
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 80% of its total assets in common stocks of utilities companies. The Fund generally will invest at least 90% of its total assets in common stocks that comprise the Underlying Intellidex. As of June 30, 2011, the Underlying Intellidex was comprised of stocks of 60 U.S. utilities companies. These companies are principally engaged in providing either energy, water, natural gas or telecommunications services. These companies may include companies that generate and supply electricity, including electricity wholesalers; distribute natural gas to customers; provide water to customers, as well as deal with associated wastewater; and provide land line or wireless telephone services. Strictly in accordance with its existing guidelines and mandated procedures, NYSE Arca, Inc. ("NYSE Arca" or the "Intellidex Provider") includes stocks principally on the basis of their capital appreciation potential that it identifies pursuant to a proprietary Intellidex methodology. As of June 30, 2011, the Underlying Intellidex included common stocks of companies with a market capitalization range of between approximately $394 million and $186 billion. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Intellidex reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.

Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. Energy Sector Risk. Changes in worldwide energy prices, exploration and production spending may adversely affect companies in the energy sector. Changes in government regulation, world events and economic conditions also affect these companies. In addition, these companies are at risk of civil liability from accidents resulting in injury, loss of life or property, pollution or other environmental damage claims and risk of loss from terrorism and natural disasters. Commodity price volatility, changes in exchange rates, imposition of import controls, increased competition, depletion of resources, development of alternative energy sources, technological developments and labor relations also could adversely affect companies in this sector. Utilities Sector Risk. Issuers in the utility sector are subject to a variety of factors that may adversely affect their business or operations, including high interest costs associated with capital construction and improvement programs; difficulty in raising adequate capital on reasonable terms in periods of high inflation and unsettled capital markets; governmental regulation of rates the issuer can charge to customers; costs associated with compliance, and adjusting to changes to, environmental and other regulations; effects of economic slowdowns and surplus capacity; increased competition from other providers of utility services; inexperience with, and potential losses resulting from, a developing deregulatory environment; costs associated with the reduced availability of certain types of fuel, occasionally reduced availability and high costs of natural gas for resale, and the effects of energy conservation policies; effects of a national energy policy and lengthy delays, and greatly increased costs and other problems, associated with the design, construction, licensing, regulation and operation of nuclear facilities for electric generation, including, among other considerations, the problems associated with the use of radioactive materials and the disposal of radioactive wastes; technological innovations that may render existing plants, equipment or products obsolete; difficulty in obtaining regulatory approval of new technologies; lack of compatibility of telecommunications equipment; and potential impact of terrorist activities on the utility industry and its customers and the impact of natural or man-made disasters. Additionally, nuclear facility operators may face greater regulatory scrutiny as a result of the disaster at the Fukushima I Nuclear Power Plant in Japan, which may lead to reduced profits and investor interest for these type of issuers. Issuers in the utilities sector also may be subject to regulation by various governmental authorities and may be affected by the imposition of special tariffs and changes in tax laws, regulatory policies and accounting standards. Market Risk. Securities in the Underlying Intellidex are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Intellidex. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Intellidex is comprised of issuers in a single industry or sector of the economy. By focusing in an industry or sector, the Fund faces more risks than if it were diversified broadly over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries or the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Intellidex for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Intellidex, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Intellidex. In addition, the performance of the Fund and the Underlying Intellidex may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Intellidex resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Intellidex. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Intellidex, even if that security generally is underperforming. Small and Medium Capitalization Company Risk. Investing in securities of small and medium capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Often small and medium capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund's volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund's performance. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC or any other government agency.

[1] Invesco PowerShares Capital Management LLC (the "Adviser") has agreed to waive fees and/or pay Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, brokerage commissions and other trading expenses, sub-licensing fees, offering costs, taxes and extraordinary expenses) from exceeding 0.60% of the Fund's average daily net assets per year (the "Expense Cap") until at least August 31, 2012, and neither the Adviser nor the Fund can discontinue the agreement prior to its expiration. The expenses borne by the Adviser are subject to recapture by the Adviser for up to three years from the date the fee or expense was borne by the Adviser, but no recapture payment will be made by the Fund if it would result in the Fund exceeding its Expense Cap.

Investment Strategy, Heading	rr_StrategyHeading	Principal Investment Strategies
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 80% of its total assets in common stocks of companies that have a consistent record of dividend increases. The Fund generally will invest at least 90% of its total assets in dividend-paying common stocks that comprise the Underlying Index. Strictly in accordance with its existing guidelines and mandated procedures, Mergent®, Inc. ("Mergent" or the "Index Provider") includes stock in the Underlying Index, principally on the basis of dividend yield and consistent growth in dividends. As of June 30, 2011, the Underlying Index was composed of approximately 50 companies with a market capitalization range of between approximately $289 million and $186 billion. The Underlying Index contains only stocks and no debt or fixed income securities. To qualify for the universe of "Dividend Achievers," an issuer must have increased its annual regular cash dividend, on a pre-tax basis, for each of the last 10 fiscal years. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Investment Strategy, Portfolio Concentration	rr_StrategyPortfolioConcentration	The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. Dividend Paying Security Risk. Securities that pay high dividends as a group can fall out of favor with the market, causing such companies to underperform companies that do not pay high dividends. Also changes in the dividend policies of the companies in the Underlying Index and the capital resources available for such companies' dividend payments may affect the Fund. High Yield Securities Risk. High yield securities typically involve greater risk and are less liquid than higher grade issues. Changes in general economic conditions, changes in the financial condition of the issuers and changes in interest rates may adversely impact the ability of issuers of high yield securities to make timely payments of interest and principal. Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the fund Holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Index may be composed of issuers in a single industry or sector of the economy. If the Fund is focused in an industry or sector, it may present more risks than if it were diversified broadly over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries or the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Index resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming. Small and Medium Capitalization Company Risk. Investing in securities of small and medium capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Often small and medium capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC or any other government agency.

PowerShares Dynamic Media Portfolio (Prospectus Summary) | PowerShares Dynamic Media Portfolio

PowerShares Dynamic Media Portfolio

Investment Objective

The PowerShares Dynamic Media Portfolio (the "Fund") seeks investment results
that generally correspond (before fees and expenses) to the price and yield of
the Dynamic Media IntellidexSM Index (the "Underlying Intellidex").

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors may pay brokerage commissions on their
purchases and sales of Shares, which are not reflected in the table or the
example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		PowerShares Dynamic Media Portfolio
Management Fees		0.50%
Other Expenses		0.19%
Total Annual Fund Operating Expenses		0.69%
Fee Waivers and Expense Assumption	[1]	0.06%
Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption	[1]	0.63%

Example

This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. This example assumes that you invest
$10,000 in the Fund for the time periods indicated and then sell all of your
Shares at the end of those periods. The example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. The cost under the one year example is equal to the Total
Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the
first year and the Total Annual Fund Operating Expenses thereafter. This example
does not include the brokerage commissions that investors may pay to buy and
sell Shares of the Fund.

Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Expense Example (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
PowerShares Dynamic Media Portfolio	64	215	378	853

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover rate was 53% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 80% of its total assets in common stocks
of media companies. The Fund generally will invest at least 90% of its total
assets in common stocks that comprise the Underlying Intellidex. As of June 30,
2011, the Underlying Intellidex was composed of stocks of 30 U.S. media
companies. These companies are engaged principally in the development,
production, sale and distribution of goods or services used in the media
industry. These companies may include, for example, advertising, marketing and
public relations companies; companies that own, operate, or broadcast free or
pay television, radio or cable stations; theaters; film studios; publishers or
sellers of newspapers, magazines, books or video products; printing, cable
television and video companies and equipment providers; pay-per-view television
companies; companies involved in emerging technologies for the broadcast and
media industries; cellular communications companies; companies involved in the
development, syndication, and transmission of television, movie programming,
advertising and cellular communications; companies that distribute data-based
information; and other companies involved in the ownership, operation, or
development of media products or services. Strictly in accordance with its
existing guidelines and mandated procedures, the Intellidex Provider includes
stocks principally on the basis of their capital appreciation potential that it
identifies pursuant to a proprietary Intellidex methodology. As of June 30,
2011, the Underlying Intellidex included common stocks of companies with a
market capitalization range of between approximately $454 million and $71
billion.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying
Intellidex reflects a concentration in that industry or group of industries. The
Fund will not otherwise concentrate its investments in securities of issuers in
any one industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Media Industry Concentration Risk. Companies engaged in design, production or
distribution of goods or services for the media industry (including television
or radio broadcasting or manufacturing, publishing, recordings and musical
instruments, motion pictures and photography) may become obsolete quickly. Media
companies are subject to risks that include cyclicality of revenues and earnings,
a decrease in the discretionary income of targeted individuals, changing consumer
tastes and interests, fierce competition in the industry and the potential for
increased government regulation. Media company revenues largely are dependent on
advertising spending. A weakening general economy or a shift from online to
other forms of advertising may lead to a reduction in discretionary spending on
online advertising. Additionally, competitive pressures and government
regulation can significantly affect companies in the media industry.

Market Risk. Securities in the Underlying Intellidex are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Intellidex.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets, and disruption in the creation/redemption process of the
Fund. Any of these factors may lead to the Shares trading at a premium or
discount to the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or debt
instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Intellidex is
comprised of issuers in a single industry or sector of the economy. By focusing
in an industry or sector, the Fund faces more risks than if it were diversified
broadly over numerous industries and sectors of the economy. At times, such
industry or group of industries may be out of favor and underperform other
industries or the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Intellidex for a number of reasons. For example, the Fund incurs
operating expenses not applicable to the Underlying Intellidex, and incurs costs
in buying and selling securities, especially when rebalancing the Fund's
securities holdings to reflect changes in the composition of the Underlying
Intellidex. In addition, the performance of the Fund and the Underlying
Intellidex may vary due to asset valuation differences and differences between
the Fund's portfolio and the Underlying Intellidex resulting from legal
restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Intellidex.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Intellidex, even if that
security generally is underperforming.

Small and Medium Capitalization Company Risk. Investing in securities of small
and medium capitalization companies involves greater risk than customarily is
associated with investing in larger, more established companies. These
companies' securities may be more volatile and less liquid than those of more
established companies. These securities may have returns that vary, sometimes
significantly, from the overall securities market. Often small and medium
capitalization companies and the industries in which they focus are still
evolving and, as a result, they may be more sensitive to changing market
conditions.

Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater
portion of its assets in securities of individual issuers than a diversified
fund. As a result, changes in the market value of a single investment could
cause greater fluctuations in Share price than would occur in a diversified
fund. This may increase the Fund's volatility and cause the performance of a
relatively small number of issuers to have a greater impact on the Fund's
performance.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC
or any other government agency.

PowerShares Dynamic Market Portfolio (Prospectus Summary) | PowerShares Dynamic Market Portfolio

PowerShares Dynamic Market Portfolio

Investment Objective

The PowerShares Dynamic Market Portfolio (the "Fund") seeks investment results
that generally correspond (before fees and expenses) to the price and yield of
the Dynamic Market IntellidexSM Index (the "Underlying Intellidex").

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors may pay brokerage commissions on their
purchases and sales of Shares, which are not reflected in the table or the
example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		PowerShares Dynamic Market Portfolio
Management Fees		0.50%
Other Expenses		0.14%
Total Annual Fund Operating Expenses		0.64%
Fee Waivers and Expense Assumption	[1]	0.04%
Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption	[1]	0.60%

Example

This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. This example assumes that you invest
$10,000 in the Fund for the time periods indicated and then sell all of your
Shares at the end of those periods. The example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. The cost under the one year example is equal to the Total
Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the
first year and the Total Annual Fund Operating Expenses thereafter. This example
does not include the brokerage commissions that investors may pay to buy and
sell Shares of the Fund.

Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Expense Example (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
PowerShares Dynamic Market Portfolio	61	201	353	795

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover rate was 107% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 90% of its total assets in common stocks
that comprise the Underlying Intellidex. As of June 30, 2011, the Underlying
Intellidex was composed of 100 U.S. stocks that NYSE Arca, Inc. ("NYSE Arca" or
the "Intellidex Provider"), strictly in accordance with its existing guidelines
and mandated procedures, included pursuant to a proprietary method. The
Underlying Intellidex selection methodology seeks to identify and select
companies from the U.S. marketplace with superior risk-return profiles. As of
June 30, 2011, the Underlying Intellidex included common stocks of companies
with a market capitalization range of between approximately $363 million and
$206 billion.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying
Intellidex reflects a concentration in that industry or group of industries. The
Fund will not otherwise concentrate its investments in securities of issuers in
any one industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Market Risk. Securities in the Underlying Intellidex are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Intellidex.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for Shares, losses from trading in secondary
markets, and disruption in the creation/redemption process of the Fund. Any of
these factors may lead to Shares trading at a premium or discount to the Fund's
net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
of an issuer may be particularly sensitive to general movements in the stock market;
or a drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock of
an issuer in the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a company's
capital structure, in terms of priority to corporate income, and therefore will be
subject to greater dividend risk than preferred stocks or debt instruments of
such issuers.

Concentration Risk. A significant percentage of the Underlying Intellidex may be
composed of issuers in a single industry or sector of the economy. If the Fund
is focused in an industry or sector, it may present more risks than if it were
broadly diversified over numerous industries and sectors of the economy. At
times, such industry or group of industries may be out of favor and underperform
other industries of the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Intellidex for a number of reasons. For example, the Fund incurs
operating expenses not applicable to the Underlying Intellidex, and incurs costs
in buying and selling securities, especially when rebalancing the Fund's
securities holdings to reflect changes in the composition of the Underlying
Intellidex. In addition, the performance of the Fund and the Underlying
Intellidex may vary due to asset valuation differences and differences between
the Fund's portfolio and the Underlying Intellidex resulting from legal
restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Intellidex.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Intellidex, even if that
security generally is underperforming.

Medium Capitalization Company Risk. Investing in securities of medium
capitalization companies involves greater risk than customarily is associated
with investing in larger, more established companies. These companies'
securities may be more volatile and less liquid than those of more established
companies. These securities may have returns that vary, sometimes significantly,
from the overall securities market. Often medium capitalization companies and
the industries in which they focus are still evolving and, as a result, they may
be more sensitive to changing market conditions.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC
or any other government agency.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover was 12% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 80% of its total assets in common stocks
of aerospace and defense companies. The Fund generally will invest at least 90%
of its total assets in common stocks that comprise the Underlying Index. As of
June 30, 2011, the Underlying Index was composed of stocks of approximately 52
U.S. companies whose shares are listed on the New York Stock Exchange ("NYSE"),
NYSE Amex or the NASDAQ Stock Market, LLC ("NASDAQ"). These companies are
engaged principally in the research, development, manufacture, operation and
support of defense, military, homeland security and space operations. These may
include, for example, companies that provide the following products or services:
defense electronics, aircraft, naval vessels, missiles, spacecraft and launch
vehicles, ground vehicles, communications, sensors, information technology and
network centric warfare, unmanned vehicles, satellite-based services and
ground-based equipment and electronics. Strictly in accordance with its existing
guidelines and mandated procedures, ISBC, LLC ("ISBC" or the "Index Provider")
identifies stocks for the Underlying Index. As of June 30, 2011, the Underlying
Index included common stocks of companies with a market capitalization range of
between approximately $210 million and $82.1 billion.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying Index
reflects a concentration in that industry or group of industries. The Fund will
not otherwise concentrate its investments in securities of issuers in any one
industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Aerospace and Defense Industry Concentration Risk. Government aerospace and
defense regulation and spending policies can significantly affect the aerospace
and defense industry because many companies involved in the aerospace and
defense industry rely to a large extent on U.S. (and other) Government demand
for their products and services. There are significant inherent risks in
contracting with the U.S. Government that could have a material adverse effect
on the business, financial condition and results of operations of industry
participants.

Market Risk. Securities in the Underlying Index are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Index.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets, and disruption in the creation/redemption process of the
Fund. Any of these factors may lead to the Shares trading at a premium or
discount to the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or debt
instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Index is
comprised of issuers in a single industry or sector of the economy. By focusing
in an industry or sector, the Fund faces more risks than if it were diversified
broadly over numerous industries and sectors of the economy. At times, such
industry or group of industries may be out of favor and underperform other
industries or the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Index for a number of reasons. For example, the Fund incurs operating
expenses not applicable to the Underlying Index, and incurs costs in buying and

cause greater fluctuations in Share price than would occur in a diversified fund.
This may increase the Fund's volatility and cause the performance of a relatively
small number of issuers to have a greater impact on the Fund's performance.

will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover rate was 102% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 80% of its total assets in common stocks
of retail companies. The Fund generally will invest at least 90% of its total
assets in common stocks that comprise the Underlying Intellidex. As of June 30,
2011, the Underlying Intellidex was composed of stocks of 30 U.S. retailers.
These companies are engaged principally in operating general merchandise stores
such as department stores, discount stores, warehouse clubs and superstores;
specialty stores, including apparel, electronics, accessories and footwear
stores; and home improvement and home furnishings stores. Dealers of motor
vehicles and parts, auction houses or rental companies also may be included.
Strictly in accordance with its existing guidelines and mandated procedures, the
Intellidex Provider includes stocks principally on the basis of their capital
appreciation potential that it identifies pursuant to a proprietary Intellidex
methodology. As of June 30, 2011, the Underlying Intellidex included common
stocks of companies with a market capitalization range of between approximately
$372 million and $183 billion.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying
Intellidex reflects a concentration in that industry or group of industries. The
Fund will not otherwise concentrate its investments in securities of issuers in
any one industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Retail Industry Concentration Risk. The retail industry may be affected by the
performance of the domestic and international economy, interest rates,
competition and consumer confidence. The success of companies in the retail
industry depends heavily on disposable household income and consumer spending,
and changes in demographics and consumer preferences can affect the success of
retail products.

The success of retail products may be strongly affected by fads, marketing
campaigns and other factors affecting supply and demand. In addition, the retail
industry is subject to severe competition.

Market Risk. Securities in the Underlying Intellidex are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Intellidex.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets, and disruption in the creation/redemption process of the
Fund. Any of these factors may lead to the Shares trading at a premium or
discount to the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or debt
instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Intellidex is
comprised of issuers in a single industry or sector of the economy. By focusing
in an industry or sector, the Fund faces more risks than if it were diversified
broadly over numerous industries and sectors of the economy. At times, such
industry or group of industries may be out of favor and underperform other
industries or the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Intellidex for a number of reasons. For example, the Fund incurs
operating expenses not applicable to the Underlying Intellidex, and incurs costs
in buying and selling securities, especially when rebalancing the Fund's
securities holdings to reflect changes in the composition of the Underlying
Intellidex. In addition, the performance of the Fund and the Underlying
Intellidex may vary due to asset valuation differences and differences between
the Fund's portfolio and the Underlying Intellidex resulting from legal
restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Intellidex.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Intellidex, even if that
security generally is underperforming.

Small and Medium Capitalization Company Risk. Investing in securities of small
and medium capitalization companies involves greater risk than customarily is
associated with investing in larger, more established companies. These
companies' securities may be more volatile and less liquid than those of more
established companies. These securities may have returns that vary, sometimes
significantly, from the overall securities market. Often small and medium
capitalization companies and the industries in which they focus are still
evolving and, as a result, they may be more sensitive to changing market
conditions.

Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater
portion of its assets in securities of individual issuers than a diversified
fund. As a result, changes in the market value of a single investment could
cause greater fluctuations in Share price than would occur in a diversified fund.
This may increase the Fund's volatility and cause the performance of a relatively
small number of issuers to have a greater impact on the Fund's performance.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC
or any other government agency.

Performance

The bar chart below shows how the Fund has performed. The table below the bar
chart shows the Fund's average annual total returns (before and after taxes).
The bar chart and table provide an indication of the risks of investing in the
Fund by showing how the Fund's total return has varied from year to year and by
showing how the Fund's average annual total returns compared with a broad
measure of market performance. The Fund's performance reflects fee waivers, if
any, absent which, performance would have been lower. Although the information
shown in the bar chart and the table gives you some idea of the risks involved
in investing in the Fund, the Fund's past performance (before and after taxes)
is not necessarily indicative of how the Fund will perform in the future.

[1] Invesco PowerShares Capital Management (the "Adviser") has agreed to waive fees and/or pay Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, brokerage commissions and other trading expenses, sub-licensing fees, offering costs, taxes and extraordinary expenses) from exceeding 0.60% of the Fund's average daily net assets per year (the "Expense Cap") until at least August 31, 2012, and neither the Adviser nor the Fund can discontinue the agreement prior to its expiration. The expenses borne by the Adviser are subject to recapture by the Adviser for up to three years from the date the fee or expense was borne by the Adviser, but no recapture payment will be made by the Fund if it would result in the Fund exceeding its Expense Cap.

Investment Strategy, Heading	rr_StrategyHeading	Principal Investment Strategies
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 90% of its total assets in the component securities that comprise the Underlying Index. The Underlying Index is comprised of common stocks of "mid value" U.S. companies (including real estate investment trusts ("REITs")) that Research Affiliates, LLC ("RAFI Affiliates" or the "Index Provider") classifies based on its Fundamental Index® methodology. Strictly in accordance with its existing guidelines and mandated procedures, the Index Provider identifies the common stocks for inclusion in the Underlying Index from a universe of the 2,500 largest U.S. companies. The use of the word "Fundamental" in the Fund's name reflects the fact that, in identifying the common stocks, the Index Provider uses fundamental measures of company size, rather than market capitalization (company share price multiplied by number of shares outstanding). The Index Provider uses the following fundamental measures to include common stocks in the Underlying Index: book value, income, sales and dividends. It then calculates a composite fundamental weight for each common stock by equally weighting the above four fundamental measures. The Index Provider then ranks each common stock by its fundamental weight and, based on this ranking, divides the common stocks into three size groups: "large," "mid" and "small." The common stocks it ranks in the top 70% of the eligible universe by fundamental weight comprise the "large" size group, the next 20% comprise the "mid" size group, and the final 10% comprise the "small" size group. The Index Provider further divides the "mid" size group into "growth," "core" or "value" subsets based on the Fundamental Index® methodology style score, which uses a combination of fundamental growth rates and fundamental valuation ratios. The Underlying Index is composed only of those common stocks that the Index Provider classifies as both "mid" and "value." The Fund generally will invest at least 80% of its total assets in common stocks of "fundamentally mid" companies. The Fund considers "fundamentally mid" companies to be those companies that comprise the Underlying Index. The use of the word "Pure" in the Fund's name reflects that, in selecting securities for the Underlying Index, the Index Provider includes only those securities that it has classified as "value." Although "value" funds also could include some stocks that, based on their classification, would be considered "growth" or "core," the Underlying Index contains only those stocks that the Index Provider classifies as pure "value" stocks. The Fund generally will invest in all of the securities comprising its Underlying Index in proportion to their weightings in the Underlying Index. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.

The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. "Fundamentally Mid" Company Risk. Investing in common stocks of "fundamentally mid" companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies' common stocks may be more volatile and less liquid than those of more established companies. These common stocks may have returns that vary, sometimes significantly, from the overall stock market. Often "fundamentally mid" companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. REIT Risk. Although the Fund will not invest in real estate directly, the REITs in which the Fund invests are subject to risks inherent in the direct ownership of real estate. These risks include, but are not limited to, a possible lack of mortgage funds and associated interest rate risks, overbuilding, property vacancies, increases in property taxes and operating expenses, changes in zoning laws, losses due to environmental damages and changes in neighborhood values and appeal to purchasers. Value Risk. "Value" securities are subject to the risk that the valuations never improve or that the returns on "value" securities are less than returns on other styles of investing or the overall stock market. Thus, the value of the Fund's investments will vary and at times may be lower or higher than that of other types of investments. Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk.

In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers.

The expenses borne by the Adviser are subject to recapture by the Adviser for up to three years from the date the fee or expense was borne by the Adviser, but no recapture payment will be made by the Fund if it would result in the Fund exceeding its Expense Cap.

Portfolio Turnover	rr_PortfolioTurnoverTextBlock	The Fund pays transaction costs, such as commissions, when it purchases and sells securities (or "turns over" its portfolio). A higher portfolio turnover will cause the Fund to incur additional transaction costs and may result in higher taxes when Fund Shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the example, may affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 114% of the average value of its portfolio.

Expense Example, Narrative	rr_ExpenseExampleNarrativeTextBlock	This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. This example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your Shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The cost under the one year example is equal to the Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the first year and the Total Annual Fund Operating Expenses thereafter. This example does not include the brokerage commissions that investors may pay to buy and sell Shares of the Fund.

Investment Strategy, Heading	rr_StrategyHeading	Principal Investment Strategies
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 80% of its total assets in common stocks of banking companies. The Fund generally will invest at least 90% of its total assets in common stocks that comprise the Underlying Intellidex. As of June 30, 2011, the Underlying Intellidex was composed of stocks of 30 U.S. banking companies. These companies include money center banks, regional banks or thrifts that are engaged principally in providing a range of consumer and commercial products and services, including depository and cash management services; consumer and commercial loans; residential and commercial real estate loans; and other related banking services. Strictly in accordance with its existing guidelines and mandated procedures, NYSE Arca, Inc. ("NYSE Arca" or the "Intellidex Provider") includes stocks principally on the basis of their capital appreciation potential that it identifies pursuant to a proprietary Intellidex methodology. As of June 30, 2011, the Underlying Intellidex included common stocks of companies with a market capitalization range of between approximately $310 million and $31 billion. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Intellidex reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.

The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. Banking Industry Concentration Risk. The Fund may be susceptible to adverse economic or regulatory occurrences affecting the banking industry. Banks are subject to extensive government regulation that may affect the scope of their activities, their profitability, the prices that they can charge and the amount of capital that they must maintain. In addition, unstable interest rates can have a disproportionate effect on the banking industry; banks whose securities the Fund may purchase may themselves have concentrated portfolios of loans or investments that make them vulnerable to economic conditions that affect that industry. Increased competition also may affect adversely the profitability or viability of banks. Market Risk. Securities in the Underlying Intellidex are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Intellidex. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Intellidex is comprised of issuers in a single industry or sector of the economy. By focusing in an industry or sector, the Fund faces more risks than if it were diversified broadly over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries or the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Intellidex for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Intellidex, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Intellidex. In addition, the performance of the Fund and the Underlying Intellidex may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Intellidex resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Intellidex. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Intellidex, even if that security generally is underperforming. Small and Medium Capitalization Company Risk. Investing in securities of small and medium capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Often small and medium capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund's volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund's performance. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC or any other government agency.

PowerShares NASDAQ Internet Portfolio (Prospectus Summary) | PowerShares NASDAQ Internet Portfolio

PowerShares NASDAQ Internet Portfolio

Investment Objective

The PowerShares NASDAQ Internet Portfolio (the "Fund") seeks investment results
that generally correspond (before fees and expenses) to the price and yield of
the NASDAQ Internet IndexSM (the "Underlying Index").

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors may pay brokerage commissions on their
purchases and sales of Shares, which are not reflected in the table or the
example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	PowerShares NASDAQ Internet Portfolio
Management Fees	0.60%
Other Expenses	none
Total Annual Fund Operating Expenses	0.60%

Example

This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. This example assumes that you invest
$10,000 in the Fund for the time periods indicated and then sell all of your
Shares at the end of those periods. The example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. The cost under the one year example is equal to the Total
Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the
first year and the Total Annual Fund Operating Expenses thereafter. This example
does not include the brokerage commissions that investors may pay to buy and
sell Shares of the Fund.

Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Expense Example (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
PowerShares NASDAQ Internet Portfolio	61	192	335	750

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and sells
securities (or "turns over" its portfolio). A higher portfolio turnover will cause
the Fund to incur additional transaction costs and may result in higher taxes when
Fund Shares are held in a taxable account. These costs, which are not reflected in
Total Annual Fund Operating Expenses or in the example, may affect the Fund's
performance. During the most recent fiscal year, the Fund's portfolio turnover was
20% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 80% of its total assets in common stocks
of internet companies. The Fund generally will invest at least 90% of its total
assets in common stocks that comprise the Underlying Index. The Underlying Index
is designed to track the performance of the largest and most liquid U.S.-listed
companies engaged in internet-related businesses that are listed on one of the
three major U.S. stock exchanges. Companies in the Underlying Index include
internet software and services companies involved in internet-related services,
including internet access providers, internet search engines, web hosting,
website design and e-commerce. NASDAQ OMX Group, Inc. (the "Index Provider")
compiles the Underlying Index strictly in accordance with its existing
guidelines and mandated procedures. As of June 30, 2011, the Underlying Index
included 66 companies with a market capitalization range of between
approximately $478 million and $38 billion.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying Index
reflects a concentration in that industry or group of industries. The Fund will
not otherwise concentrate its investments in securities of issuers in any one
industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Internet Software and Services Sector Risk. Competitive pressures, such as
technological developments, fixed-rate pricing and the ability to attract and
retain skilled employees, can significantly affect the internet software and
services sector. Changing domestic and international demand, research and
development costs, availability and price of components and product
obsolescence also can affect profitability of companies in this sector.

Market Risk. Securities in the Underlying Index are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Index.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in secondary
markets and disruption in the creation/redemption process of the Fund. Any of
these factors may lead to the Shares trading at a premium or discount to the
Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make anticipated
dividend payments because, among other reasons, the issuer of the security
experiences a decline in its financial condition. Common stock is subordinated
to preferred stocks, bonds and other debt instruments in a company's capital
structure, in terms of priority to corporate income, and therefore will be subject
to greater dividend risk than preferred stocks or debt instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Index is comprised
of issuers in a single industry or sector of the economy. By focusing in an
industry or sector, the Fund faces more risks than if it were diversified broadly
over numerous industries and sectors of the economy. At times, such industry or
group of industries may be out of favor and underperform other industries or the
market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the Underlying
Index for a number of reasons. For example, the Fund incurs operating expenses
not applicable to the Underlying Index, and incurs costs in buying and selling
securities, especially when rebalancing the Fund's securities holdings to reflect
changes in the composition of the Underlying Index. In addition, the performance
of the Fund and the Underlying Index may vary due to asset  valuation differences
and differences between the Fund's portfolio and the  Underlying Index resulting
from legal restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Index.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Index, even if that
security generally is underperforming.

Small and Medium Capitalization Company Risk. Investing in securities of small
and medium capitalization companies involves greater risk than customarily is
associated with investing in larger, more established companies. These
companies' securities may be more volatile and less liquid than those of more
established companies. These securities may have returns that vary, sometimes
significantly, from the overall securities market. Often small and medium
capitalization companies and the industries in which they focus are still
evolving and, as a result, they may be more sensitive to changing market
conditions.

Large Capitalization Company Risk. Companies with large market capitalizations
may go in and out of favor based on market and economic conditions. Although
larger companies tend to be less volatile than companies with smaller market
capitalizations, returns on investments in securities of large capitalization
U.S. companies could trail the returns on investments in securities of smaller
companies.

Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater
portion of its assets in securities of individual issuers than a diversified
fund. As a result, changes in the market value of a single investment could
cause greater fluctuations in Share price than would occur in a diversified
fund. This may increase the Fund's volatility and cause the performance of a
relatively small number of issuers to have a greater impact on the Fund's
performance.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC
or any other government agency.

Risk/Return, Heading	rr_RiskReturnHeading	PowerShares Dynamic Networking Portfolio
Investment Objective, Heading	rr_ObjectiveHeading	Investment Objective
investment Objective, Primary	rr_ObjectivePrimaryTextBlock	The PowerShares Dynamic Networking Portfolio (the "Fund") seeks investment results that generally correspond (before fees and expenses) to the price and yield of the Dynamic Networking IntellidexSM Index (the "Underlying Intellidex").
Expense, Heading	rr_ExpenseHeading	Fund Fees and Expenses
Expense, Narrative	rr_ExpenseNarrativeTextBlock	This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund ("Shares"). Investors may pay brokerage commissions on their purchases and sales of Shares, which are not reflected in the table or the example below.
Operating Expenses, Caption	rr_OperatingExpensesCaption	Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)
Portfolio Turnover, Heading	rr_PortfolioTurnoverHeading	Portfolio Turnover
Portfolio Turnover	rr_PortfolioTurnoverTextBlock	The Fund pays transaction costs, such as commissions, when it purchases and sells securities (or "turns over" its portfolio). A higher portfolio turnover will cause the Fund to incur additional transaction costs and may result in higher taxes when Fund Shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the example, may affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 61% of the average value of its portfolio.

Expense Example, Heading	rr_ExpenseExampleHeading	Example
Expense Example, Narrative	rr_ExpenseExampleNarrativeTextBlock	This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. This example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your Shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The cost under the one year example is equal to the Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the first year and the Total Annual Fund Operating Expenses thereafter. This example does not include the brokerage commissions that investors may pay to buy and sell Shares of the Fund.

Investment Strategy, Heading	rr_StrategyHeading	Principal Investment Strategies
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 80% of its total assets in common stocks of networking companies. The Fund generally will invest at least 90% of its total assets in common stocks that comprise the Underlying Intellidex. As of June 30, 2011, the Underlying Intellidex was composed of stocks of 30 U.S. networking companies. These companies are engaged principally in the development, manufacture, sale or distribution of products, services or technologies that support the flow of electronic information, including voice, data, images and commercial transactions. These companies may include, for example, providers of telecommunications and networking equipment; data storage; systems software; internet hardware including servers; routers; switches and related equipment; systems for data encryption and security; internet services including hosting and commercial exchanges; fiber optics; satellites; cable equipment and other companies involved in supporting the flow of information. Strictly in accordance with its existing guidelines and mandated procedures, the Intellidex Provider includes stocks principally on the basis of their capital appreciation potential that it identifies pursuant to a proprietary Intellidex methodology. As of June 30, 2011, the Underlying Intellidex included common stocks of companies with a market capitalization range of between approximately $374 million and $95 billion. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Intellidex reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Investment Strategy, Portfolio Concentration	rr_StrategyPortfolioConcentration	The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Intellidex reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. Networking Industry Concentration Risk. The networking industry is evolving rapidly and can be significantly affected by corporate capital expenditure trends, competitive pressures such as the ability to attract and retain skilled employees and obsolescence due to rapid technological innovation or changing consumer preferences. Further, many network companies rely on a combination of patents, copyrights, trademarks and trade secret laws to establish and protect their proprietary rights in their products and technologies. There can be no assurance that the steps taken by network companies to protect their proprietary rights will be adequate to prevent misappropriation of their technology or that competitors will not independently develop technologies that are substantially equivalent or superior to such companies' technology. Market Risk. Securities in the Underlying Intellidex are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Intellidex. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Intellidex is comprised of issuers in a single industry or sector of the economy. By focusing in an industry or sector, the Fund faces more risks than if it were diversified broadly over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries or the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Intellidex for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Intellidex, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Intellidex. In addition, the performance of the Fund and the Underlying Intellidex may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Intellidex resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Intellidex. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Intellidex, even if that security generally is underperforming. Small and Medium Capitalization Company Risk. Investing in securities of small and medium capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Often small and medium capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund's volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund's performance. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC or any other government agency.

As a result, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund.

[1] Invesco PowerShares Capital Management LLC (the" Adviser") has agreed to waive fees and/or pay Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, brokerage commissions and other trading expenses, sub-licensing fees, offering costs, taxes and extraordinary expenses) from exceeding 0.60% of the Fund's average daily net assets per year (the "Expense Cap") until at least August 31, 2012, and neither the Adviser nor the Fund can discontinue the agreement prior to its expiration. The expenses borne by the Adviser are subject to recapture by the Adviser for up to three years from the date the fee or expense was borne by the Adviser, but no recapture payment will be made by the Fund if it would result in the Fund exceeding its Expense Cap.

The Fund generally will invest at least 90% of its total assets in common stocks that comprise the Underlying Intellidex. As of June 30, 2011, the Underlying Intellidex was comprised of stocks of 60 U.S. consumer companies. These companies are principally engaged in the businesses of providing consumer goods and services that have non-cyclical characteristics, including tobacco, textiles, food and beverage, and non-discretionary retail. Strictly in accordance with its existing guidelines and mandated procedures, NYSE Arca, Inc. ("NYSE Arca" or the "Intellidex Provider") includes stocks principally on the basis of their capital appreciation potential that it identifies pursuant to a proprietary Intellidex methodology. As of June 30, 2011, the Underlying Intellidex included common stocks of companies with a market capitalization range of between $431 million and $183 billion. Concentration Policy.

Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. Consumer Staples Sector Risk. Changes in the worldwide economy, consumer spending, competition, demographics and consumer preferences, exploration and production spending may adversely affect companies in the consumer staples sector. Companies in this sector also are affected by changes in government regulation, world events and economic conditions. Market Risk. Securities in the Underlying Intellidex are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Intellidex. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Intellidex is comprised of issuers in a single industry or sector of the economy. By focusing in an industry or sector, the Fund faces more risks than if it were diversified broadly over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries or the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Intellidex for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Intellidex, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Intellidex. In addition, the performance of the Fund and the Underlying Intellidex may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Intellidex resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Intellidex. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Intellidex, even if that security generally is underperforming. Small and Medium Capitalization Company Risk. Investing in securities of small and medium capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Often small and medium capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC or any other government agency.

PowerShares Golden Dragon Halter USX China Portfolio (Prospectus Summary) | PowerShares Golden Dragon Halter USX China Portfolio

PowerShares Golden Dragon Halter USX China Portfolio

Investment Objective

The PowerShares Golden Dragon Halter USX China Portfolio (the "Fund") seeks
investment results that generally correspond (before fees and expenses) to the
price and yield of the Halter USX China IndexSM (the "Underlying Index").

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors may pay brokerage commissions on their
purchases and sales of Shares, which are not reflected in the table or the
example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		PowerShares Golden Dragon Halter USX China Portfolio
Management Fees		0.50%
Other Expenses		0.22%
Total Annual Fund Operating Expenses		0.72%
Fee Waivers and Expense Assumption	[1]	0.02%
Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption	[1]	0.70%

Example

This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. This example assumes that you invest
$10,000 in the Fund for the time periods indicated and then sell all of your
Shares at the end of those periods. The example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. The cost under the one year example is equal to the Total
Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the
first year and the Total Annual Fund Operating Expenses thereafter. This example
does not include the brokerage commissions that investors may pay to buy and
sell Shares of the Fund.

Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Expense Example (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
PowerShares Golden Dragon Halter USX China Portfolio	72	228	399	893

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover was 15% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 80% of its total assets in equity
securities of companies deriving a majority of their revenues from the People's
Republic of China. The Fund generally will invest at least 90% of its total
assets in equity securities that comprise the Underlying Index. As of June 30,
2011, the Underlying Index was composed of stocks of approximately 202 U.S.
exchange-listed companies that derive a majority of their revenues from the
People's Republic of China. Strictly in accordance with its existing guidelines
and mandated procedures, Halter Financial Group, Inc. ("Halter Financial" or the
"Index Provider") includes stocks in the Underlying Index to provide access to
the unique economic opportunities taking place in China while still providing
investors with the transparency offered with U.S.-listed securities. As of June
30, 2011, the Underlying Index included common stocks of companies with a market
capitalization range of between approximately $51 million and $260 billion.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying Index
reflects a concentration in that industry or group of industries. The Fund will
not otherwise concentrate its investments in securities of issuers in any one
industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

China Exposure Risk. The value of the securities of companies that derive the
majority of their revenues from China is likely to be more volatile than that of
other issuers. The economy of China differs, often unfavorably, from the U.S.
economy in such respects as structure, general development, government
involvement, wealth distribution, rate of inflation, growth rate, allocation of
resources and capital reinvestment, among others.

Market Risk. Securities in the Underlying Index are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Index.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets, and disruption in the creation/redemption process of the
Fund. Any of these factors may lead to the Shares trading at a premium or discount
to the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or debt
instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Index may be
composed of issuers in a single industry or sector of the economy. If the Fund
is focused in an industry or sector, it may present more risks than if it were
broadly diversified over numerous industries and sectors of the economy. At
times, such industry or group of industries may be out of favor and underperform
other industries of the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Index for a number of reasons. For example, the Fund incurs operating
expenses not applicable to the Underlying Index, and incurs costs in buying and
selling securities, especially when rebalancing the Fund's securities holdings
to reflect changes in the composition of the Underlying Index. In addition, the
performance of the Fund and the Underlying Index may vary due to asset valuation
differences and differences between the Fund's portfolio and the Underlying
Index resulting from legal restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Index.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Index, even if that
security generally is underperforming.

Small and Medium Capitalization Company Risk. Investing in securities of small
and medium capitalization companies involves greater risk than customarily is
associated with investing in larger, more established companies. These
companies' securities may be more volatile and less liquid than those of more
established companies. These securities may have returns that vary, sometimes
significantly, from the overall securities market. Often small and medium
capitalization companies and the industries in which they focus are still
evolving and, as a result, they may be more sensitive to changing market
conditions.

Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater
portion of its assets in securities of individual issuers than a diversified
fund. As a result, changes in the market value of a single investment could
cause greater fluctuations in Share price than would occur in a diversified
fund. This may increase the Fund's volatility and cause the performance of a
relatively small number of issuers to have a greater impact on the Fund's
performance.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC
or any other government agency.

Performance

Investment Objective

The PowerShares Global Listed Private Equity Portfolio (the "Fund") seeks
investment results that generally correspond (before fees and expenses) to the
price and yield of the Red Rocks Global Listed Private Equity IndexSM (the
"Underlying Index").

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors may pay brokerage commissions on their
purchases and sales of Shares, which are not reflected in the table or the
example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

with the cost of investing in other funds. This example assumes that you invest
$10,000 in the Fund for the time periods indicated and then sell all of your
Shares at the end of those periods. The example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses

PowerShares Global Listed Private Equity Portfolio	72	230	403	904

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover was 112% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 90% of its total assets in securities
(including American depositary receipts ("ADRs") and global depositary receipts
("GDRs")), that comprise the Underlying Index. As of June 30, 2011, the
Underlying Index was composed of securities, ADRs and GDRs of 60 private equity
companies, including business development companies ("BDCs"), master limited
partnerships ("MLPs") and other vehicles listed on a nationally recognized
exchange worldwide whose principal business is to invest in, lend capital to or
provide services to privately-held companies (collectively "listed private
equity companies"). Strictly in accordance with its existing guidelines and
mandated procedures, Red Rocks Capital LLC ("Red Rocks" or the "Index Provider")
includes securities in the Underlying Index pursuant to a proprietary selection
methodology. As of June 30, 2011, the Underlying Index included common stocks of
companies with a market capitalization range of between approximately $100
million and $30 billion.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying Index
reflects a concentration in that industry or group of industries. The Fund will
not otherwise concentrate its investments in securities of issuers in any one
industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Risk of Investing in Listed Private Equity Companies. There are certain risks
inherent in investing in listed private equity companies, which encompass BDCs
and other financial institutions or vehicles whose principal business is to
invest in and lend capital to privately held companies. The Investment Company
Act of 1940, as amended (the "1940 Act"), imposes certain restraints upon the
operations of a BDC. For example, BDCs are required to invest at least 70% of
their total assets primarily in securities of private companies or thinly traded
U.S. public companies, cash, cash equivalents, U.S. government securities and
high quality debt investments that mature in one year or less. Generally, little
public information exists for private and thinly traded companies, and there is a
risk that investors may not be able to make a fully informed investment decision.
With investments in debt instruments, there is a risk that the issuer may default
on its payments or declare bankruptcy. Additionally, a BDC may incur
indebtedness only in amounts such that the BDC's asset coverage equals at least
200% after such incurrence. These limitations on asset mix and leverage may
prohibit the way that the BDC raises capital. BDCs generally invest in less mature
private companies, which involve greater risk than well-established, publicly-traded
companies.

Foreign Securities Risk. Since the Underlying Index may include ADRs and GDRs,
the Fund's investments involve risks of investing in foreign securities in
addition to the risks associated with domestic securities. In general, foreign
companies are not subject to the regulatory requirements of U.S. companies and,
as such, there may be less publicly available information about these companies.
Moreover, foreign companies often are subject to less stringent requirements
regarding accounting, auditing, financial reporting and record-keeping than are
U.S. companies, and therefore, not all material information regarding these
companies will be available.

Restrictions on Investments. A significant portion of the Underlying Index is
composed of BDCs or other investment companies. The Fund may not acquire greater
than 3% of the total outstanding shares of such companies. As a result, this
limitation could inhibit the Fund's ability to purchase certain of the
securities in the Underlying Index in the proportions represented in the
Underlying Index. In these circumstances, the Fund would be required to use
sampling techniques, which could increase the risk of tracking error.

Risks of Investing in MLP Units. An MLP is an entity receiving partnership
taxation treatment under the U.S. Internal Revenue Code of 1986, as amended (the
"Internal Revenue Code"), and whose partnership interests or "units" are traded
on securities exchanges like shares of corporate stock. Investments in MLPs
units are subject to certain risks inherent in the structure of MLPs, including
(i) tax risks, (ii) the limited ability to elect or remove management or the
general partner or managing member, (iii) limited voting rights and (iv)
conflicts of interest between the general partner or managing member and its
affiliates and the limited partners or members.

Market Risk. Securities in the Underlying Index are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Index.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets, and disruption in the creation/redemption process of the
Fund. Any of these factors may lead to the Shares trading at a premium or
discount to the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make anticipated
dividend payments because, among other reasons, the issuer of the security
experiences a decline in its financial condition. Common stock is subordinated
to preferred stocks, bonds and other debt instruments in a company's capital
structure, in terms of priority to corporate income, and therefore will be subject
to greater dividend risk than preferred stocks or debt instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Index may be
composed of issuers in a single industry or sector of the economy. If the Fund
is focused in an industry or sector, it may present more risks than if it were
broadly diversified over numerous industries and sectors of the economy. At
times, such industry or group of industries may be out of favor and underperform
other industries of the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Index for a number of reasons. For example, the Fund incurs operating
expenses not applicable to the Underlying Index, and incurs costs in buying and
selling securities, especially when rebalancing the Fund's securities holdings
to reflect changes in the composition of the Underlying Index. In addition, the
performance of the Fund and the Underlying Index may vary due to asset valuation
differences and differences between the Fund's portfolio and the Underlying
Index resulting from legal restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Index.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Index, even if that
security generally is underperforming.

Small and Medium Capitalization Company Risk. Investing in securities of small
and medium capitalization companies involves greater risk than customarily is
associated with investing in larger, more established companies. These
companies' securities may be more volatile and less liquid than those of more
established companies. These securities may have returns that vary, sometimes
significantly, from the overall securities market. Often small and medium
capitalization companies and the industries in which they focus are still
evolving and, as a result, they may be more sensitive to changing market
conditions.

Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater
portion of its assets in securities of individual issuers than a diversified
fund. As a result, changes in the market value of a single investment could
cause greater fluctuations in Share price than would occur in a diversified
fund. This may increase the Fund's volatility and cause the performance of a
relatively small number of issuers to have a greater impact on the Fund's
performance.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC
or any other government agency.

Annual Total Returns-Calendar Years

The Fund's year-to-date total return for the six months ended June 30, 2011 was
5.12%.

        Best Quarter                    Worst Quarter

After-tax returns in the table below are calculated using the historical highest
individual federal marginal income tax rates and do not reflect the impact of
state and local taxes. Actual after-tax returns depend on an investor's tax
situation and may differ from those shown, and after-tax returns shown are not
relevant to investors who hold Shares through tax-deferred arrangements, such as
401(k) plans or individual retirement accounts. In the event of negative
performance displayed in the table below, the Fund's returns after taxes on
distributions and sale of Fund Shares are calculated assuming that an investor
has sufficient capital gains of the same character from other investments to
offset any capital losses from the sale of Fund Shares so that the investor may
deduct the losses in full. As a result, the Fund's returns after taxes on
distributions and sale of Fund Shares may exceed the Fund's returns before taxes
and/or returns after taxes on distributions.

PowerShares Dynamic Energy Exploration & Production Portfolio (Prospectus Summary) | PowerShares Dynamic Energy Exploration & Production Portfolio

PowerShares Dynamic Energy Exploration & Production Portfolio

Investment Objective

The PowerShares Dynamic Energy Exploration & Production Portfolio (the "Fund")
seeks investment results that generally correspond (before fees and expenses) to
the price and yield of the Dynamic Energy Exploration & Production IntellidexSM
Index (the "Underlying Intellidex").

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors may pay brokerage commissions on their
purchases and sales of Shares, which are not reflected in the table or the
example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		PowerShares Dynamic Energy Exploration & Production Portfolio
Management Fees		0.50%
Other Expenses		0.26%
Total Annual Fund Operating Expenses		0.76%
Fee Waivers and Expense Assumption	[1]	0.13%
Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption	[1]	0.63%

Example

This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. This example assumes that you invest
$10,000 in the Fund for the time periods indicated and then sell all of your
Shares at the end of those periods. The example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. The cost under the one year example is equal to the Total
Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the
first year and the Total Annual Fund Operating Expenses thereafter. This example
does not include the brokerage commissions that investors may pay to buy and sell
Shares of the Fund.

Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Expense Example (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
PowerShares Dynamic Energy Exploration & Production Portfolio	64	230	410	930

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover rate was 57% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 80% of its total assets in common stocks
of companies engaged in energy exploration and production. The Fund generally
will invest at least 90% of its total assets in common stocks that comprise the
Underlying Intellidex. As of June 30, 2011, the Underlying Intellidex was
composed of stocks of 30 U.S. companies involved in the exploration and
production of natural resources used to produce energy. These companies are
engaged principally in exploration, extraction and production of crude oil and
natural gas from land-based or offshore wells. These companies include petroleum
refineries that process the crude oil into finished products, such as gasoline
and automotive lubricants, and companies involved in gathering and processing
natural gas, and manufacturing natural gas liquid. Strictly in accordance with
its existing guidelines and mandated procedures, the Intellidex Provider
includes stocks principally on the basis of their capital appreciation potential
that it identifies pursuant to a proprietary Intellidex methodology. As of June
30, 2011, the Underlying Intellidex included common stocks of companies with a
market capitalization range of between approximately $343 million and $396
billion.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying
Intellidex reflects a concentration in that industry or group of industries. The
Fund will not otherwise concentrate its investments in securities of issuers in
any one industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Energy Exploration and Production Industry Concentration Risk. Companies in the
energy exploration and production industry are subject to extensive government
regulation, which may increase the cost of business and limit these companies'
earnings. In addition, these companies are at risk of civil liability from
accidents resulting in injury or loss of life or property, pollution or other
environmental damage claims and risk of loss from terrorism and natural
disasters. Companies in this industry could be adversely affected by levels and
volatility of global energy prices, commodity price volatility, changes in
exchange rates and interest rates, imposition of import controls, increased
competition, capital expenditures on exploration and production, depletion of
resources, development of alternative energy sources and energy conservation
efforts, technological developments and labor relations.

Market Risk. Securities in the Underlying Intellidex are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Intellidex.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets, and disruption in the creation/redemption process of the
Fund. Any of these factors may lead to the Shares trading at a premium or
discount to the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or debt
instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Intellidex is
comprised of issuers in a single industry or sector of the economy. By focusing
in an industry or sector, the Fund faces more risks than if it were diversified
broadly over numerous industries and sectors of the economy. At times, such
industry or group of industries may be out of favor and underperform other
industries or the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Intellidex for a number of reasons. For example, the Fund incurs
operating expenses not applicable to the Underlying Intellidex, and incurs costs
in buying and selling securities, especially when rebalancing the Fund's
securities holdings to reflect changes in the composition of the Underlying
Intellidex. In addition, the performance of the Fund and the Underlying
Intellidex may vary due to asset valuation differences and differences between
the Fund's portfolio and the Underlying Intellidex resulting from legal
restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Intellidex.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Intellidex, even if that
security generally is underperforming.

Small and Medium Capitalization Company Risk. Investing in securities of small
and medium capitalization companies involves greater risk than customarily is
associated with investing in larger, more established companies. These
companies' securities may be more volatile and less liquid than those of more
established companies. These securities may have returns that vary, sometimes
significantly, from the overall securities market. Often small and medium
capitalization companies and the industries in which they focus are still
evolving and, as a result, they may be more sensitive to changing market
conditions.

Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater
portion of its assets in securities of individual issuers than a diversified
fund. As a result, changes in the market value of a single investment could
cause greater fluctuations in Share price than would occur in a diversified
fund. This may increase the Fund's volatility and cause the performance of a
relatively small number of issuers to have a greater impact on the Fund's
performance.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC
or any other government agency.

Performance

The bar chart below shows how the Fund has performed. The table below the bar
chart shows the Fund's average annual total returns (before and after taxes).
The bar chart and table provide an indication of the risks of investing in the
Fund by showing how the Fund's total return has varied from year to year and by
showing how the Fund's average annual total returns compared with a broad
measure of market performance. The Fund's performance reflects fee waivers, if
any, absent which, performance would have been lower. Although the information
shown in the bar chart and the table gives you some idea of the risks involved
in investing in the Fund, the Fund's past performance (before and after taxes)
is not necessarily indicative of how the Fund will perform in the future.

PowerShares Dynamic Banking Portfolio (Prospectus Summary) | PowerShares Dynamic Banking Portfolio

PowerShares Dynamic Banking Portfolio

Investment Objective

The PowerShares Dynamic Banking Portfolio (the "Fund") seeks investment results
that generally correspond (before fees and expenses) to the price and yield of
the Dynamic Banking IntellidexSM Index (the "Underlying Intellidex").

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors may pay brokerage commissions on their
purchases and sales of Shares, which are not reflected in the table or the
example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		PowerShares Dynamic Banking Portfolio
Management Fees		0.50%
Other Expenses		0.67%
Total Annual Fund Operating Expenses		1.17%
Fee Waivers and Expense Assumption	[1]	0.52%
Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption	[1]	0.65%

Example

This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. This example assumes that you invest
$10,000 in the Fund for the time periods indicated and then sell all of your
Shares at the end of those periods. The example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. The cost under the one year example is equal to the Total
Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the
first year and the Total Annual Fund Operating Expenses thereafter. This example
does not include the brokerage commissions that investors may pay to buy and
sell Shares of the Fund.

Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Expense Example (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
PowerShares Dynamic Banking Portfolio	66	320	593	1,374

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover rate was 114% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 80% of its total assets in common stocks
of banking companies. The Fund generally will invest at least 90% of its total
assets in common stocks that comprise the Underlying Intellidex. As of June 30,
2011, the Underlying Intellidex was composed of stocks of 30 U.S. banking
companies. These companies include money center banks, regional banks or thrifts
that are engaged principally in providing a range of consumer and commercial
products and services, including depository and cash management services;
consumer and commercial loans; residential and commercial real estate loans; and
other related banking services. Strictly in accordance with its existing
guidelines and mandated procedures, NYSE Arca, Inc. ("NYSE Arca" or the
"Intellidex Provider") includes stocks principally on the basis of their capital
appreciation potential that it identifies pursuant to a proprietary Intellidex
methodology. As of June 30, 2011, the Underlying Intellidex included common
stocks of companies with a market capitalization range of between approximately
$310 million and $31 billion.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying
Intellidex reflects a concentration in that industry or group of industries. The
Fund will not otherwise concentrate its investments in securities of issuers in
any one industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Banking Industry Concentration Risk. The Fund may be susceptible to adverse
economic or regulatory occurrences affecting the banking industry. Banks are
subject to extensive government regulation that may affect the scope of their
activities, their profitability, the prices that they can charge and the amount
of capital that they must maintain. In addition, unstable interest rates can
have a disproportionate effect on the banking industry; banks whose securities
the Fund may purchase may themselves have concentrated portfolios of loans or
investments that make them vulnerable to economic conditions that affect that
industry. Increased competition also may affect adversely the profitability or
viability of banks.

Market Risk. Securities in the Underlying Intellidex are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Intellidex.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets, and disruption in the creation/redemption process of the
Fund. Any of these factors may lead to the Shares trading at a premium or
discount to the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or debt
instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Intellidex is
comprised of issuers in a single industry or sector of the economy. By focusing
in an industry or sector, the Fund faces more risks than if it were diversified
broadly over numerous industries and sectors of the economy. At times, such
industry or group of industries may be out of favor and underperform other
industries or the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Intellidex for a number of reasons. For example, the Fund incurs
operating expenses not applicable to the Underlying Intellidex, and incurs costs
in buying and selling securities, especially when rebalancing the Fund's
securities holdings to reflect changes in the composition of the Underlying
Intellidex. In addition, the performance of the Fund and the Underlying
Intellidex may vary due to asset valuation differences and differences between
the Fund's portfolio and the Underlying Intellidex resulting from legal
restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Intellidex.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Intellidex, even if that
security generally is underperforming.

Small and Medium Capitalization Company Risk. Investing in securities of small
and medium capitalization companies involves greater risk than customarily is

conditions.

Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater
portion of its assets in securities of individual issuers than a diversified
fund. As a result, changes in the market value of a single investment could
cause greater fluctuations in Share price than would occur in a diversified
fund. This may increase the Fund's volatility and cause the performance of a
relatively small number of issuers to have a greater impact on the Fund's
performance.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC
or any other government agency.

performance displayed in the table below, the Fund's returns after taxes on
distributions and sale of Fund Shares are calculated assuming that an investor
has sufficient capital gains of the same character from other investments to
offset any capital losses from the sale of Fund Shares so that the investor may
deduct the losses in full. As a result, the Fund's returns after taxes on
distributions and sale of Fund Shares may exceed the Fund's returns before
taxes and/or returns after taxes on
distributions.

Strictly in accordance with its existing guidelines and mandated procedures, the Intellidex Provider includes stocks principally on the basis of their capital appreciation potential that it identifies pursuant to a proprietary Intellidex methodology. As of June 30, 2011, the Underlying Intellidex included common stocks of companies with a market capitalization range of between approximately $341 million and $95 billion. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Intellidex reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.

Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. Semiconductors Industry Concentration Risk. Competitive pressures, intense competition, aggressive pricing, technological developments, changing demand, research and development costs, availability and price of components and product obsolescence can significantly affect the semiconductors industry. Market Risk. Securities in the Underlying Intellidex are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Intellidex. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Intellidex is comprised of issuers in a single industry or sector of the economy. By focusing in an industry or sector, the Fund faces more risks than if it were diversified broadly over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries or the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Intellidex for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Intellidex, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Intellidex. In addition, the performance of the Fund and the Underlying Intellidex may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Intellidex resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Intellidex. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Intellidex, even if that security generally is underperforming. Small and Medium Capitalization Company Risk. Investing in securities of small and medium capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Often small and medium capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund's volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund's performance. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC or any other government agency.

[1] Invesco PowerShares Capital Management LLC (the "Adviser") has agreed to waive fees and/or pay Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, brokerage commissions and other trading expenses, sub-licensing fees, offering costs, taxes and extraordinary expenses) from exceeding 0.60% of the Fund's average daily net assets per year (the "Expense Cap") until at least August 31, 2012, and neither the Adviser nor the Fund can discontinue the agreement prior to its expiration. The expenses borne by the Adviser are subject to recapture by the Adviser for up to three years from the date the fee or expense was borne by the Adviser, but no recapture payment will be made by the Fund if it would result in the Fund exceeding its Expense Cap.

PowerShares Fundamental Pure Small Value Portfolio (Prospectus Summary) | PowerShares Fundamental Pure Small Value Portfolio

PowerShares Fundamental Pure Small Value Portfolio

Investment Objective

The PowerShares Fundamental Pure Small Value Portfolio (the "Fund) seeks
investment results that generally correspond (before fees and expenses) to the
price and yield of the RAFI® Fundamental Small Value Index (the "Underlying
Index").

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors may pay brokerage commissions on their
purchases and sales of Shares, which are not reflected in the table or the
example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		PowerShares Fundamental Pure Small Value Portfolio
Management Fees		0.29%
Other Expenses		0.51%
Total Annual Fund Operating Expenses		0.80%
Fee Waivers and Expense Assumption	[1]	0.17%
Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption	[1]	0.63%

Example

This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. This example assumes that you invest
$10,000 in the Fund for the time periods indicated and then sell all of your
Shares at the end of those periods. The example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. The cost under the one year example is equal to the Total
Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the
first year and the Total Annual Fund Operating Expenses thereafter. This example
does not include the brokerage commissions that investors may pay to buy and
sell Shares of the Fund.

Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Expense Example (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
PowerShares Fundamental Pure Small Value Portfolio	64	238	427	974

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Shares are held in a taxable account. These costs, which are
not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the fiscal year ended April 30, 2011, the
Fund's portfolio turnover rate was 90% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 90% of its total assets in the component
securities that comprise the Underlying Index. The Underlying Index is comprised
of common stocks of "small value" U.S. companies (including real estate
investment trusts ("REITs")) that Research Affiliates, LLC ("RAFI Affiliates" or
the "Index Provider") classifies based on its Fundamental Index® methodology.
Strictly in accordance with its existing guidelines and mandated procedures, the
Index Provider identifies the common stocks for inclusion in the Underlying
Index from a universe of the 2,500 largest U.S. companies. The use of the word
"Fundamental" in the Fund's name reflects the fact that, in identifying the
common stocks, the Index Provider uses fundamental measures of company size,
rather than market capitalization (company share price multiplied by number of
shares outstanding). The Index Provider uses the following fundamental measures
to include common stocks in the Underlying Index: book value, income, sales and
dividends. It then calculates a composite fundamental weight is calculated for
each common stock by equally weighting the above four fundamental measures. The
Index Provider then ranks each common stock by its fundamental weight and, based
on this ranking, divides the common stocks into three size groups: "large,"
"mid" and "small." The common stocks it ranks in the top 70% of the eligible
universe by fundamental weight comprise the "large" size group, the next 20%
comprise the "mid" size group, and the final 10% comprise the "small" size
group. The Index Provider further divides the "small" size group into "growth,"
"core" or "value" subsets based on the Fundamental Index® methodology style
score, which uses a combination of fundamental growth rates and fundamental
valuation ratios. The Underlying Index is composed only of those common stocks
that the Index Provider classifies as both "small" and "value." The Fund
generally will invest at least 80% of its total assets in common stocks of
"fundamentally small" companies. The Fund considers "fundamentally small"
companies to be those companies that comprise the Underlying Index.

The use of the word "Pure" in the Fund's name reflects that, in selecting
securities for the Underlying Index, the Index Provider includes only those
securities that it has classified as "value." Although "value" funds also could
include some stocks that, based on their classification, would be considered
"growth" or "core," the Underlying Index contains only those stocks that the
Index Provider classifies as pure "value" stocks. The Fund generally will invest
in all of the securities comprising its Underlying Index in proportion to their
weightings in the Underlying Index.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying Index
reflects a concentration in that industry or group of industries. The Fund will
not otherwise concentrate its investments in securities of issuers in any one
industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

"Fundamentally Small" Company Risk. Investing in common stocks of "fundamentally
small" companies involves greater risk than customarily is associated with
investing in larger, more established companies. These companies' common stocks
may be more volatile and less liquid than those of more established companies.
These common stocks may have returns that vary, sometimes significantly, from
the overall stock market. Often "fundamentally small" companies and the
industries in which they focus are still evolving and, as a result, may be more
sensitive to changing market conditions.

REIT Risk. Although the Fund will not invest in real estate directly, the REITs
in which the Fund invests are subject to risks inherent in the direct ownership
of real estate. These risks include, but are not limited to, a possible lack of
mortgage funds and associated interest rate risks, overbuilding, property
vacancies, increases in property taxes and operating expenses, changes in zoning
laws, losses due to environmental damages and changes in neighborhood values and
appeal to purchasers.

Value Risk. "Value" securities are subject to the risk that the valuations never
improve or that the returns on "value" securities are less than returns on other
styles of investing or the overall stock market. Thus, the value of the Fund's
investments will vary and at times may be lower or higher than that of other
types of investments.

Market Risk. Securities in the Underlying Index are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Index.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets, and disruption in the creation/redemption process of the
Fund. Any of these factors may lead to the Shares trading at a premium or
discount to the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or debt
instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Index may be
comprised of issuers in a single industry or sector of the economy. If the Fund
is focused in an industry or sector, it may present more risks than if it were
diversified broadly over numerous industries and sectors of the economy. At
times, such industry or group of industries may be out of favor and underperform
other industries or the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Index for a number of reasons. For example, the Fund incurs operating
expenses not applicable to the Underlying Index, and incurs costs in buying and
selling securities, especially when rebalancing the Fund's securities holdings
to reflect changes in the composition of the Underlying Index. In addition, the
performance of the Fund and the Underlying Index may vary due to asset valuation
differences and differences between the Fund's portfolio and the Underlying
Index resulting from legal restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Index.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Index, even if that
security generally is underperforming.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the
Federal Deposit Insurance Corporation or any other government agency.

During the most recent fiscal year, the Fund's portfolio turnover rate was 19% of the average value of its portfolio.

Investment Strategy, Heading	rr_StrategyHeading	Principal Investment Strategies
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 90% of its total assets in common stocks that comprise the Underlying Index. As of June 30, 2011, the Underlying Index was composed of approximately 1,500 U.S. stocks that FTSE International Limited and Research Affiliates LLC ("FTSE" and "RA" or the "Index Provider"), strictly in accordance with its existing guidelines and mandated procedures, included to track the performance of small and medium-sized U.S. equity stocks based on the following four fundamental measures of firm size: book value, income, cash flow and dividends. As of June 30, 2011, the Underlying Index included common stocks of companies with a market capitalization range of between approximately $17 million and $19 billion. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Investment Strategy, Portfolio Concentration	rr_StrategyPortfolioConcentration	The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock of an issuer may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock of an issuer in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Index may be composed of issuers in a single industry or sector of the economy. If the Fund is focused in an industry or sector, it may present more risks than if it were broadly diversified over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries of the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Index resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming. Small and Medium Capitalization Company Risk. Investing in securities of small and medium capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Often small and medium capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC or any other government agency.

[1] Invesco PowerShares Capital Management LLC (the "Adviser") has agreed to waive fees and/or pay Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, brokerage commissions and other trading expenses, sub-licensing fees, offering costs, taxes and extraordinary expenses) from exceeding 0.60% of the Fund's average daily net assets per year (the "Expense Cap") until at least August 31, 2012, and neither the Adviser nor the Fund can discontinue the agreement prior to its expiration. The expenses borne by the Adviser are subject to recapture by the Adviser for up to three years from the date the fee or expense was borne by the Adviser, but no recapture payment will be made by the Fund if it would result in the Fund exceeding its Expense Cap.

Portfolio Turnover	rr_PortfolioTurnoverTextBlock	The Fund pays transaction costs, such as commissions, when it purchases and sells securities (or "turns over" its portfolio). A higher portfolio turnover will cause the Fund to incur additional transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the example, may affect the Fund's performance. During the fiscal year ended April 30, 2011, the Fund's portfolio turnover rate was 41% of the average value of its portfolio.

Expense Example, Narrative	rr_ExpenseExampleNarrativeTextBlock	This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. This example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your Shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The cost under the one year example is equal to the Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the first year and the Total Annual Fund Operating Expenses thereafter. This example does not include the brokerage commissions that investors may pay to buy and sell Shares of the Fund.

Investment Strategy, Heading	rr_StrategyHeading	Principal Investment Strategies
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 90% of its total assets in the component securities that comprise the Underlying Index. The Underlying Index is comprised of common stocks of "large core" U.S. companies (including real estate investment trusts ("REITs")) that Research Affiliates, LLC ("RAFI Affiliates" or the "Index Provider") classifies based on its Fundamental Index® methodology. Strictly in accordance with its existing guidelines and mandated procedures, the Index Provider identifies the common stocks for inclusion in the Underlying Index from a universe of the 2,500 largest U.S. companies. The use of the word "Fundamental" in the Fund's name reflects the fact that, in identifying common stocks, the Index Provider uses fundamental measures of company size, rather than market capitalization (company share price multiplied by number of shares outstanding). The Index Provider uses the following fundamental measures to include common stocks in the Underlying Index: book value, income, sales and dividends. It then calculates a composite fundamental weight for each common stock by equally weighting the above four fundamental measures. The Index Provider then ranks each common stock by its fundamental weight and, based on this ranking, divides the common stocks into three size groups: "large," "mid" and "small." The common stocks it ranks in the top 70% of the eligible universe by fundamental weight comprise the "large" size group, the next 20% comprise the "mid" size group, and the final 10% comprise the "small" size group. The Index Provider further divides the "large" size group into "growth," "core" or "value" subsets based on the Fundamental Index® methodology style score, which uses a combination of fundamental growth rates and fundamental valuation ratios. The Underlying Index is composed only of those common stocks that the Index Provider classifies as both "large" and "core." The Fund generally will invest at least 80% of its total assets in common stocks of "fundamentally large" companies. The Fund considers "fundamentally large" companies to be those companies that comprise the Underlying Index. The use of the word "Pure" in the Fund's name reflects that, in selecting securities for the Underlying Index, the Index Provider includes only those securities that it has classified as "core." Although "core" funds also could include some stocks that, based on their classification, would be considered "growth" or "value," the Underlying Index contains only those stocks that the Index Provider classifies as pure "core" stocks. The Fund generally will invest in all of the securities comprising its Underlying Index in proportion to their weightings in the Underlying Index. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Investment Strategy, Portfolio Concentration	rr_StrategyPortfolioConcentration	The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. Core Risk. The returns on "core" securities may or may not move in tandem with the returns on other styles of investing or the overall stock market. Thus, the value of the Fund's investments will vary and at times may be lower or higher than that of other types of investments. "Fundamentally Large" Company Risk. Returns on investments in common stocks of "fundamentally large" U.S. companies could trail the returns on investments in common stocks of smaller companies or other large companies based on market capitalization. REIT Risk. Although the Fund will not invest in real estate directly, the REITs in which the Fund invests are subject to risks inherent in the direct ownership of real estate. These risks include, but are not limited to, a possible lack of mortgage funds and associated interest rate risks, overbuilding, property vacancies, increases in property taxes and operating expenses, changes in zoning laws, losses due to environmental damages and changes in neighborhood values and appeal to purchasers. Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Index may be comprised of issuers in a single industry or sector of the economy. If the Fund is focused in an industry or sector, it may present more risks than if it were diversified broadly over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries or the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Index resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Investment Strategy, Heading	rr_StrategyHeading	Principal Investment Strategies
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 80% of its total assets in common stocks of media companies. The Fund generally will invest at least 90% of its total assets in common stocks that comprise the Underlying Intellidex. As of June 30, 2011, the Underlying Intellidex was composed of stocks of 30 U.S. media companies. These companies are engaged principally in the development, production, sale and distribution of goods or services used in the media industry. These companies may include, for example, advertising, marketing and public relations companies; companies that own, operate, or broadcast free or pay television, radio or cable stations; theaters; film studios; publishers or sellers of newspapers, magazines, books or video products; printing, cable television and video companies and equipment providers; pay-per-view television companies; companies involved in emerging technologies for the broadcast and media industries; cellular communications companies; companies involved in the development, syndication, and transmission of television, movie programming, advertising and cellular communications; companies that distribute data-based information; and other companies involved in the ownership, operation, or development of media products or services. Strictly in accordance with its existing guidelines and mandated procedures, the Intellidex Provider includes stocks principally on the basis of their capital appreciation potential that it identifies pursuant to a proprietary Intellidex methodology. As of June 30, 2011, the Underlying Intellidex included common stocks of companies with a market capitalization range of between approximately $454 million and $71 billion. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Intellidex reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.

The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. Media Industry Concentration Risk. Companies engaged in design, production or distribution of goods or services for the media industry (including television or radio broadcasting or manufacturing, publishing, recordings and musical instruments, motion pictures and photography) may become obsolete quickly. Media companies are subject to risks that include cyclicality of revenues and earnings, a decrease in the discretionary income of targeted individuals, changing consumer tastes and interests, fierce competition in the industry and the potential for increased government regulation. Media company revenues largely are dependent on advertising spending. A weakening general economy or a shift from online to other forms of advertising may lead to a reduction in discretionary spending on online advertising. Additionally, competitive pressures and government regulation can significantly affect companies in the media industry. Market Risk. Securities in the Underlying Intellidex are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Intellidex. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Intellidex is comprised of issuers in a single industry or sector of the economy. By focusing in an industry or sector, the Fund faces more risks than if it were diversified broadly over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries or the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Intellidex for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Intellidex, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Intellidex. In addition, the performance of the Fund and the Underlying Intellidex may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Intellidex resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Intellidex. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Intellidex, even if that security generally is underperforming. Small and Medium Capitalization Company Risk. Investing in securities of small and medium capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Often small and medium capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund's volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund's performance. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC or any other government agency.

This may increase the Fund's volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund's performance.

[1] Invesco PowerShares Capital Management LLC (the "Adviser") has agreed to waive fees and/or pay Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, brokerage commissions and other trading expenses, sub-licensing fees, offering costs, taxes and extraordinary expenses) from exceeding 0.60% of the Fund's average daily net assets per year (the "Expense Cap") until at least August 31, 2012, and neither the Adviser nor the Fund can discontinue the agreement prior to its expiration. The expenses borne by the Adviser are subject to recapture by the Adviser for up to three years from the date the fee or expense was borne by the Adviser, but no recapture payment will be made by the Fund if it would result in the Fund exceeding its Expense Cap.

Investment Strategy, Heading	rr_StrategyHeading	Principal Investment Strategies
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 90% of its total assets in common stocks that comprise the Underlying Intellidex. If the composition of the Underlying Intellidex changes, the Fund will continue to invest at least 80% of its total assets in over-the-counter ("OTC") securities. As of June 30, 2011, the Underlying Intellidex was composed of 100 OTC market securities that NYSE Arca, Inc. ("NYSE Arca" or the "Intellidex Provider"), strictly in accordance with its existing guidelines and mandated procedures, included pursuant to a proprietary method. The Underlying Intellidex selection methodology identifies and selects companies from The NASDAQ Stock Market LLC ("NASDAQ") with superior risk-return profiles. As of June 30, 2011, the Underlying Intellidex included common stocks of companies with a market capitalization range of between approximately $324 million and $42 billion. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Intellidex reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Investment Strategy, Portfolio Concentration	rr_StrategyPortfolioConcentration	The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Intellidex reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. Market Risk. Securities in the Underlying Intellidex are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Intellidex. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock of an issuer may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock of an issuer in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Intellidex may be composed of issuers in a single industry or sector of the economy. If the Fund is focused in an industry or sector, it may present more risks than if it were broadly diversified over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries of the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Intellidex for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Intellidex, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Intellidex. In addition, the performance of the Fund and the Underlying Intellidex may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Intellidex resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Intellidex. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Intellidex, even if that security generally is underperforming. Small and Medium Capitalization Company Risk. Investing in securities of small and medium capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Often small and medium capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC or any other government agency.

PowerShares Water Resources Portfolio (Prospectus Summary) | PowerShares Water Resources Portfolio

PowerShares Water Resources Portfolio

Investment Objective

The PowerShares Water Resources Portfolio (the "Fund") seeks investment results
that generally correspond (before fees and expenses) to the price and yield of
the Palisades Water Index (the "Underlying Index").

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors may pay brokerage commissions on their
purchases and sales of Shares, which are not reflected in the table or the
example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		PowerShares Water Resources Portfolio
Management Fees		0.50%
Other Expenses		0.16%
Total Annual Fund Operating Expenses		0.66%
Fee Waivers and Expense Assumption	[1]	none
Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption	[1]	0.66%

Example

This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. This example assumes that you invest
$10,000 in the Fund for the time periods indicated and then sell all of your
Shares at the end of those periods. The example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. The cost under the one year example is equal to the Total
Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the
first year and the Total Annual Fund Operating Expenses thereafter. This example
does not include the brokerage commissions that investors may pay to buy and
sell Shares of the Fund.

Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Expense Example (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
PowerShares Water Resources Portfolio	67	211	368	822

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover was 13% of the average value of its portfolio.

Principal Investment Strategies

The Fund normally will invest at least 90% of its total assets in common stocks
and American depositary receipts ("ADRs") that comprise the Palisades Water
Index (the "Underlying Index"). The components of the Underlying Index are
selected based on the objective of providing a representative indicator of the
water business through the inclusion of companies whose water or water-related
activities stand to benefit from meeting the issues associated with the
provision of water and the management of water resources. The Underlying Index
was created by, and is a trademark of, Palisades Water Index Associates, LLC
(the "Index Provider"). As of June 30, 2011, the Underlying Index was composed
of stocks of 32 companies that are publicly traded in the United States.
Strictly in accordance with its existing guidelines and rules, the Index
Provider will include small and medium capitalization stocks as a portion of the
Underlying Index. As of June 30, 2011, the Underlying Index included companies
with a market capitalization range of between approximately $160 million and $30
billion. The Fund generally invests in all of the securities comprising its
Underlying Index in proportion to their weightings in the Underlying Index.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Risk of Concentrating in the Water Industry. Adverse developments in the water
industry may significantly affect the value of the Shares of the Fund. Companies
involved in the water industry are subject to environmental considerations,
taxes, government regulation, price and supply fluctuations, competition and
water conservation.

Foreign Securities Risk. Since the Underlying Index may include ADRs, the Fund's
investments involve risks of investing in foreign securities that are in
addition to the risks associated with domestic securities. Foreign companies, in
general, are not subject to the regulatory requirements of U.S. companies and,
as such, there may be less publicly available information about these companies.
Moreover, foreign companies are often subject to less stringent requirements
regarding accounting, auditing, financial reporting and record-keeping than are
U.S. companies, and therefore, not all material information regarding these
companies will be available.

Sampling Risk. The Fund's use of a representative sampling approach will result
in its holding a smaller number of securities than are in the Underlying Index.
As a result, an adverse development respecting an issuer of securities held by
the Fund could result in a greater decline in NAV than would be the case if the
Fund held all of the securities in the Underlying Index. To the extent the assets
in the Fund are smaller, these risks will be greater.

Market Risk. Securities in the Underlying Index are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Index.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets, and disruption in the creation/redemption process of the
Fund. Any of these factors may lead to the Shares trading at a premium or
discount to the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or debt
instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Index is
comprised of issuers in a single industry or sector of the economy. By focusing
in an industry or sector, the Fund faces more risks than if it were diversified
broadly over numerous industries and sectors of the economy. At times, such
industry or group of industries may be out of favor and underperform other
industries or the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Index for a number of reasons. For example, the Fund incurs operating
expenses not applicable to the Underlying Index, and incurs costs in buying and
selling securities, especially when rebalancing the Fund's securities holdings
to reflect changes in the composition of the Underlying Index. The Fund does not
purchase all of the securities in the Underlying Index. Instead, the Adviser
utilizes a "sampling" methodology in seeking to achieve the Fund's investment
objective. In addition, the performance of the Fund and the Underlying Index may
vary due to asset valuation differences and differences between the Fund's
portfolio and the Underlying Index resulting from legal restrictions, cost or
liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Index.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Index, even if that
security generally is underperforming.

Small and Medium Capitalization Company Risk. Investing in securities of small
and medium capitalization companies involves greater risk than customarily is
associated with investing in larger, more established companies. These
companies' securities may be more volatile and less liquid than those of more
established companies. These securities may have returns that vary, sometimes
significantly, from the overall securities market. Often small and medium
capitalization companies and the industries in which they focus are still evolving
and, as a result, they may be more sensitive to changing market conditions.

Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater
portion of its assets in securities of individual issuers than a diversified
fund. As a result, changes in the market value of a single investment could
cause greater fluctuations in Share price than would occur in a diversified
fund. This may increase the Fund's volatility and cause the performance of a
relatively small number of issuers to have a greater impact on the Fund's
performance.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC
or any other government agency.

PowerShares FTSE RAFI US 1500 Small-Mid Portfolio (Prospectus Summary) | PowerShares FTSE RAFI US 1500 Small-Mid Portfolio

PowerShares FTSE RAFI US 1500 Small-Mid Portfolio

Investment Objective

The PowerShares FTSE RAFI US 1500 Small-Mid Portfolio (the "Fund") seeks
investment results that generally correspond (before fees and expenses) to the
price and yield of the FTSE RAFI US 1500 Small-Mid Index (the "Underlying
Index").

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors may pay brokerage commissions on their
purchases and sales of Shares, which are not reflected in the table or the
example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		PowerShares FTSE RAFI US 1500 Small-Mid Portfolio
Management Fees		0.29%
Other Expenses		0.17%
Total Annual Fund Operating Expenses		0.46%
Fee Waivers and Expense Assumption	[1]	0.07%
Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption	[1]	0.39%

Example

This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. This example assumes that you invest
$10,000 in the Fund for the time periods indicated and then sell all of your
Shares at the end of those periods. The example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. The cost under the one year example is equal to the Total
Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the
first year and the Total Annual Fund Operating Expenses thereafter. This example
does not include the brokerage commissions that investors may pay to buy and
sell Shares of the Fund.

Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Expense Example (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
PowerShares FTSE RAFI US 1500 Small-Mid Portfolio	40	141	251	572

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover rate was 19% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 90% of its total assets in common stocks
that comprise the Underlying Index. As of June 30, 2011, the Underlying Index
was composed of approximately 1,500 U.S. stocks that FTSE International Limited
and Research Affiliates LLC ("FTSE" and "RA" or the "Index Provider"), strictly
in accordance with its existing guidelines and mandated procedures, included to
track the performance of small and medium-sized U.S. equity stocks based on the
following four fundamental measures of firm size: book value, income, cash flow
and dividends. As of June 30, 2011, the Underlying Index included common stocks
of companies with a market capitalization range of between approximately $17
million and $19 billion.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying Index
reflects a concentration in that industry or group of industries. The Fund will
not otherwise concentrate its investments in securities of issuers in any one
industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Market Risk. Securities in the Underlying Index are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Index.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for Shares, losses from trading in secondary
markets, and disruption in the creation/redemption process of the Fund. Any of
these factors may lead to Shares trading at a premium or discount to the Fund's
net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
of an issuer may be particularly sensitive to general movements in the stock
market; or a drop in the stock market may depress the price of most or all of the
common stocks and other equity securities the Fund holds. In addition, common
stock of an issuer in the Fund's portfolio may decline in price if the issuer
fails to make anticipated dividend payments because, among other reasons, the
issuer of the security experiences a decline in its financial condition. Common
stock is subordinated to preferred stocks, bonds and other debt instruments
in a company's capital structure, in terms of priority to corporate income,
and therefore will be subject to greater dividend risk than preferred stocks or
debt instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Index may be
composed of issuers in a single industry or sector of the economy. If the Fund
is focused in an industry or sector, it may present more risks than if it were
broadly diversified over numerous industries and sectors of the economy. At
times, such industry or group of industries may be out of favor and underperform
other industries of the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Index for a number of reasons. For example, the Fund incurs operating
expenses not applicable to the Underlying Index, and incurs costs in buying and
selling securities, especially when rebalancing the Fund's securities holdings
to reflect changes in the composition of the Underlying Index. In addition, the
performance of the Fund and the Underlying Index may vary due to asset valuation
differences and differences between the Fund's portfolio and the Underlying
Index resulting from legal restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Index.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Index, even if that
security generally is underperforming.

Small and Medium Capitalization Company Risk. Investing in securities of small
and medium capitalization companies involves greater risk than customarily is
associated with investing in larger, more established companies. These
companies' securities may be more volatile and less liquid than those of more
established companies. These securities may have returns that vary, sometimes
significantly, from the overall securities market. Often small and medium
capitalization companies and the industries in which they focus are still
evolving and, as a result, they may be more sensitive to changing market
conditions.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC
or any other government agency.

Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 80% of its total assets in stocks of cleantech companies. The Fund generally will invest at least 90% of its total assets in the securities that compose the Underlying Index and American despositary receipts ("ADRs") based on the stocks in the Underlying Index. The Fund anticipates that the majority of its investment will be in the securities that compose the Underlying Index. The Underlying Index is a modified equally weighted index currently composed of stocks of publicly-traded cleantech companies and ADRs based on such stocks. Cleantech Indices LLC ("Cleantech" or the "Index Provider") considers a company to be a cleantech company if it derives at least 50% of its revenues or operating profits from cleantech businesses. Cleantech businesses are those that provide knowledge-based products (or services) that add economic value by reducing cost and raising productivity and/or product performance, while reducing the consumption of resources and the negative impact on the environment and public health. The Underlying Index focuses on companies that are leaders in the innovation and commercial deployment of cleantech products across a broad range of industries including, but not limited to, alternative energy, energy efficiency and transmission, air and water purification, advanced materials, eco-friendly agriculture, transportation, manufacturing efficiency, recycling and pollution prevention. Strictly in accordance with its existing guidelines and mandated procedures, the Index Provider identifies the securities composing the Underlying Index, which, as of June 30, 2011, included common stocks of approximately 70 companies with a market capitalization range of between approximately $200 million and $120 billion. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.

Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. Cleantech Sector Risk. There are risks in investing in the cleantech sector, including the risks of focusing investments in the water, energy and environmental sectors. Adverse developments in the water, energy and environmental sectors may significantly affect the value of the Shares. Companies involved in the water sector are subject to tax and price fluctuations and competition. Securities of companies in the energy sector are subject to swift price and supply fluctuations caused by events relating to international politics, the success of project development and tax and other governmental regulatory policies. Weak demand for the companies' products or services or for energy products and services in general, as well as negative developments in these other areas, may adversely affect the Fund's performance. Foreign Investment Risk. Investments in the securities of non-U.S. issuers involve risks beyond those associated with investments in U.S. securities. These additional risks include greater market volatility, the availability of less reliable financial information, higher transactional costs, taxation by foreign governments, decreased market liquidity and political instability. As the Fund will invest in securities denominated in foreign currencies, changes in currency exchange rates may negatively impact the Fund's returns. Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Index is comprised of issuers in a single industry or sector of the economy. By focusing in an industry or sector, the Fund faces more risks than if it were diversified broadly over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries or the market as a whole. Non-Correlation Risk.

For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Index resulting from legal restrictions, cost or liquidity constraints.

These securities may have returns that vary, sometimes significantly, from the overall securities market. Often small and medium capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC or any other government agency.

This example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your Shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The cost under the one year example is equal to the Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the first year and the Total Annual Fund Operating Expenses thereafter. This example does not include the brokerage commissions that investors may pay to buy and sell Shares of the Fund.

Investment Strategy, Heading	rr_StrategyHeading	Principal Investment Strategies
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 80% of its total assets in common stocks of pharmaceutical companies. The Fund generally will invest at least 90% of its total assets in common stocks that comprise the Underlying Intellidex. As of June 30, 2011, the Underlying Intellidex was composed of stocks of 30 U.S. pharmaceuticals companies. These companies are engaged principally in the research, development, manufacture, sale or distribution of pharmaceuticals and drugs of all types. These companies may include, for example, pharmaceutical companies and other companies involved in the research, development, manufacture, sale or distribution of drugs, including companies that facilitate the testing or regulatory approval of drugs. Strictly in accordance with its existing guidelines and mandated procedures, the Intellidex Provider includes stocks principally on the basis of their capital appreciation potential that it identifies pursuant to a proprietary Intellidex methodology. As of June 30, 2011, the Underlying Intellidex included common stocks of companies with a market capitalization range of between approximately $351 million and $182 billion. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Intellidex reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Investment Strategy, Portfolio Concentration	rr_StrategyPortfolioConcentration	The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Intellidex reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. Pharmaceuticals Industry Concentration Risk. Government approval of products and services, government regulation and reimbursement rates, product liability claims, patent expirations and protection and intense competition can significantly affect the pharmaceuticals industry. Market Risk. Securities in the Underlying Intellidex are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Intellidex. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Intellidex is comprised of issuers in a single industry or sector of the economy. By focusing in an industry or sector, the Fund faces more risks than if it were diversified broadly over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries or the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Intellidex for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Intellidex, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Intellidex. In addition, the performance of the Fund and the Underlying Intellidex may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Intellidex resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Intellidex. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Intellidex, even if that security generally is underperforming. Small and Medium Capitalization Company Risk. Investing in securities of small and medium capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Often small and medium capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund's volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund's performance. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC or any other government agency.

As a result, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund.

Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. Risk of Investing in Listed Private Equity Companies. There are certain risks inherent in investing in listed private equity companies, which encompass BDCs and other financial institutions or vehicles whose principal business is to invest in and lend capital to privately held companies. The Investment Company Act of 1940, as amended (the "1940 Act"), imposes certain restraints upon the operations of a BDC. For example, BDCs are required to invest at least 70% of their total assets primarily in securities of private companies or thinly traded U.S. public companies, cash, cash equivalents, U.S. government securities and high quality debt investments that mature in one year or less. Generally, little public information exists for private and thinly traded companies, and there is a risk that investors may not be able to make a fully informed investment decision. With investments in debt instruments, there is a risk that the issuer may default on its payments or declare bankruptcy. Additionally, a BDC may incur indebtedness only in amounts such that the BDC's asset coverage equals at least 200% after such incurrence. These limitations on asset mix and leverage may prohibit the way that the BDC raises capital. BDCs generally invest in less mature private companies, which involve greater risk than well-established, publicly-traded companies. Foreign Securities Risk. Since the Underlying Index may include ADRs and GDRs, the Fund's investments involve risks of investing in foreign securities in addition to the risks associated with domestic securities. In general, foreign companies are not subject to the regulatory requirements of U.S. companies and, as such, there may be less publicly available information about these companies. Moreover, foreign companies often are subject to less stringent requirements regarding accounting, auditing, financial reporting and record-keeping than are U.S. companies, and therefore, not all material information regarding these companies will be available. Restrictions on Investments. A significant portion of the Underlying Index is composed of BDCs or other investment companies. The Fund may not acquire greater than 3% of the total outstanding shares of such companies. As a result, this limitation could inhibit the Fund's ability to purchase certain of the securities in the Underlying Index in the proportions represented in the Underlying Index. In these circumstances, the Fund would be required to use sampling techniques, which could increase the risk of tracking error. Risks of Investing in MLP Units. An MLP is an entity receiving partnership taxation treatment under the U.S. Internal Revenue Code of 1986, as amended (the "Internal Revenue Code"), and whose partnership interests or "units" are traded on securities exchanges like shares of corporate stock. Investments in MLPs units are subject to certain risks inherent in the structure of MLPs, including (i) tax risks, (ii) the limited ability to elect or remove management or the general partner or managing member, (iii) limited voting rights and (iv) conflicts of interest between the general partner or managing member and its affiliates and the limited partners or members. Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Index may be composed of issuers in a single industry or sector of the economy. If the Fund is focused in an industry or sector, it may present more risks than if it were broadly diversified over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries of the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Index resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming. Small and Medium Capitalization Company Risk. Investing in securities of small and medium capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Often small and medium capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund's volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund's performance. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC or any other government agency.

[1] Acquired Fund Fees and Expenses are indirect fees and expenses that the Fund incurs from investing in the shares of other investment companies. Please note that the amount of Total Annual Fund Operating Expenses shown in the above table may differ from the ratio of expenses prior to waivers and/or recapture to average net assets included in the "Financial Highlights" section of this Prospectus, which reflects the operating expenses of the Fund and does not include indirect expenses such as Acquired Fund Fees and Expenses.

[2] Invesco PowerShares Capital Management LLC (the "Adviser") has agreed to waive fees and/or pay Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, brokerage commissions and other trading expenses, sub-licensing fees, offering costs, taxes and extraordinary expenses) from exceeding 0.60% of the Fund's average daily net assets per year (the "Expense Cap") until at least August 31, 2012, and neither the Adviser nor the Fund can discontinue the agreement prior to its expiration. The expenses borne by the Adviser are subject to recapture by the Adviser for up to three years from the date the fee or expense was borne by the Adviser, but no recapture payment will be made by the Fund if it would result in the Fund exceeding its Expense Cap.

PowerShares Fundamental Pure Small Core Portfolio (Prospectus Summary) | PowerShares Fundamental Pure Small Core Portfolio

PowerShares Fundamental Pure Small Core Portfolio

Investment Objective

The PowerShares Fundamental Pure Small Core Portfolio (the "Fund") seeks
investment results that generally correspond (before fees and expenses) to the
price and yield of the RAFI® Fundamental Small Core Index (the "Underlying
Index").

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors may pay brokerage commissions on their
purchases and sales of Shares, which are not reflected in the table or the
example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		PowerShares Fundamental Pure Small Core Portfolio
Management Fees		0.29%
Other Expenses		1.12%
Total Annual Fund Operating Expenses		1.41%
Fee Waivers and Expense Assumption	[1]	0.76%
Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption	[1]	0.65%

Example

This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. This example assumes that you invest
$10,000 in the Fund for the time periods indicated and then sell all of your
Shares at the end of those periods. The example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. The cost under the one year example is equal to the Total
Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the
first year and the Total Annual Fund Operating Expenses thereafter. This example
does not include the brokerage commissions that investors may pay to buy and
sell Shares of the Fund.

Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Expense Example (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
PowerShares Fundamental Pure Small Core Portfolio	66	371	699	1,625

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Shares are held in a taxable account. These costs, which are
not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the fiscal year ended April 30, 2011, the
Fund's portfolio turnover rate was 68% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 90% of its total assets in the component
securities that comprise the Underlying Index. The Underlying Index is comprised
of common stocks of "small core" U.S. companies (including real estate
investment trusts ("REITs")) that Research Affiliates, LLC ("RAFI Affiliates" or
the "Index Provider") classifies based on its Fundamental Index® methodology.
Strictly in accordance with its existing guidelines and mandated procedures, the
Index Provider identifies the common stocks for inclusion in the Underlying
Index from a universe of the 2,500 largest U.S. companies. The use of the word
"Fundamental" in the Fund's name reflects the fact that, in identifying the
common stocks, the Index Provider uses fundamental measures of company size,
rather than market capitalization (company share price multiplied by number of
shares outstanding). The Index Provider uses the following fundamental measures
to include common stocks in the Underlying Index: book value, income, sales and
dividends. It then calculates a composite fundamental weight for each common
stock by equally weighting the above four fundamental measures. The Index
Provider then ranks each common stock by its fundamental weight and, based on
this ranking, divides the common stock into three size groups: "large," "mid"
and "small." The common stocks it ranks in the top 70% of the eligible universe
by fundamental weight comprise the "large" size group, the next 20% comprise the
"mid" size group, and the final 10% comprise the "small" size group. The Index
Provider further divides the "small" size group into "growth," "core" or "value"
subsets based on the Fundamental Index® methodology style score, which uses a
combination of fundamental growth rates and fundamental valuation ratios. The
Underlying Index is composed only of those common stocks that the Index Provider
classifies as both "small" and "core." The Fund generally will invest at least
80% of its total assets in common stocks of "fundamentally small" companies. The
Fund considers "fundamentally small" companies to be those companies that
comprise the Underlying Index.

The use of the word "Pure" in the Fund's name reflects that, in selecting
securities for the Underlying Index, the Index Provider includes only those
securities that it has classified as "core." Although "core" funds also could
include some stocks that, based on their classification, would be considered
"growth" or "value," the Underlying Index contains only those stocks that the
Index Provider classifies as pure "core" stocks. The Fund generally will invest
in all of the securities comprising its Underlying Index in proportion to their
weightings in the Underlying Index.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying Index
reflects a concentration in that industry or group of industries. The Fund will
not otherwise concentrate its investments in securities of issuers in any one
industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Core Risk. The returns on "core" securities may or may not move in tandem with
the returns on other styles of investing or the overall stock market. Thus, the
value of the Fund's investments will vary and at times may be lower or higher
than that of other types of investments.

"Fundamentally Small" Company Risk. Investing in common stocks of "fundamentally
small" companies involves greater risk than customarily is associated with
investing in larger, more established companies. These companies' common stocks
may be more volatile and less liquid than those of more established companies.
These common stocks may have returns that vary, sometimes significantly, from
the overall stock market. Often "fundamentally small" companies and the
industries in which they focus are still evolving and, as a result, they may be
more sensitive to changing market conditions.

REIT Risk. Although the Fund will not invest in real estate directly, the REITs
in which the Fund invests are subject to risks inherent in the direct ownership
of real estate. These risks include, but are not limited to, a possible lack of
mortgage funds and associated interest rate risks, overbuilding, property
vacancies, increases in property taxes and operating expenses, changes in zoning
laws, losses due to environmental damages and changes in neighborhood values and
appeal to purchasers.

Market Risk. Securities in the Underlying Index are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Index.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets, and disruption in the creation/redemption process of the
Fund. Any of these factors may lead to the Shares trading at a premium or
discount to the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or debt
instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Index may be
comprised of issuers in a single industry or sector of the economy. If the Fund
is focused in an industry or sector, it may present more risks than if it were
diversified broadly over numerous industries and sectors of the economy. At
times, such industry or group of industries may be out of favor and underperform
other industries or the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Index for a number of reasons. For example, the Fund incurs operating
expenses not applicable to the Underlying Index, and incurs costs in buying and
selling securities, especially when rebalancing the Fund's securities holdings
to reflect changes in the composition of the Underlying Index. In addition, the
performance of the Fund and the Underlying Index may vary due to asset valuation
differences and differences between the Fund's portfolio and the Underlying
Index resulting from legal restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Index.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Index, even if that
security generally is underperforming.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the
Federal Deposit Insurance Corporation or any other government agency.

Performance

The bar chart below shows how the Fund has performed. The table below the bar
chart shows the Fund's average annual total returns (before and after taxes).
The bar chart and table provide an indication of the risks of investing in the
Fund by showing how the Fund's total return has varied from year to year and by
showing how the Fund's average annual total returns compared with a broad
measure of market performance. The Fund's performance reflects fee waivers, if
any, absent which, performance would have been lower. Although the information
shown in the bar chart and the table gives you some idea of the risks involved
in investing in the Fund, the Fund's past performance (before and after taxes)
is not necessarily indicative of how the Fund will perform in the future.

After-tax returns in the table below are calculated using the historical highest
individual federal marginal income tax rates and do not reflect the impact of
state and local taxes. Actual after-tax returns depend on an investor's tax
situation and may differ from those shown, and after-tax returns shown are not
relevant to investors who hold Shares through tax-deferred arrangements, such as
401(k) plans or individual retirement accounts. In the event of negative
performance displayed in the table below, the Fund's returns after taxes on
distributions and sale of Fund Shares are calculated assuming that an investor
has sufficient capital gains of the same character from other investments to
offset any capital losses from the sale of Fund Shares so that the investor may
deduct the losses in full. As a result, the Fund's returns after taxes on
distributions and sale of Fund Shares may exceed the Fund's returns before taxes
and/or returns after taxes on distributions.

Portfolio Turnover, Heading	rr_PortfolioTurnoverHeading	Portfolio Turnover
Portfolio Turnover	rr_PortfolioTurnoverTextBlock	The Fund pays transaction costs, such as commissions, when it purchases and sells securities (or "turns over" its portfolio). A higher portfolio turnover will cause the Fund to incur additional transaction costs and may result in higher taxes when Fund Shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the example, may affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover was 15% of the average value of its portfolio.

Expense Example, Heading	rr_ExpenseExampleHeading	Example
Expense Example, Narrative	rr_ExpenseExampleNarrativeTextBlock	This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. This example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your Shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The cost under the one year example is equal to the Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the first year and the Total Annual Fund Operating Expenses thereafter. This example does not include the brokerage commissions that investors may pay to buy and sell Shares of the Fund.

Investment Strategy, Heading	rr_StrategyHeading	Principal Investment Strategies
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 80% of its total assets in equity securities of companies deriving a majority of their revenues from the People's Republic of China. The Fund generally will invest at least 90% of its total assets in equity securities that comprise the Underlying Index. As of June 30, 2011, the Underlying Index was composed of stocks of approximately 202 U.S. exchange-listed companies that derive a majority of their revenues from the People's Republic of China. Strictly in accordance with its existing guidelines and mandated procedures, Halter Financial Group, Inc. ("Halter Financial" or the "Index Provider") includes stocks in the Underlying Index to provide access to the unique economic opportunities taking place in China while still providing investors with the transparency offered with U.S.-listed securities. As of June 30, 2011, the Underlying Index included common stocks of companies with a market capitalization range of between approximately $51 million and $260 billion. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Investment Strategy, Portfolio Concentration	rr_StrategyPortfolioConcentration	The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. China Exposure Risk. The value of the securities of companies that derive the majority of their revenues from China is likely to be more volatile than that of other issuers. The economy of China differs, often unfavorably, from the U.S. economy in such respects as structure, general development, government involvement, wealth distribution, rate of inflation, growth rate, allocation of resources and capital reinvestment, among others. Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Index may be composed of issuers in a single industry or sector of the economy. If the Fund is focused in an industry or sector, it may present more risks than if it were broadly diversified over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries of the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Index resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming. Small and Medium Capitalization Company Risk. Investing in securities of small and medium capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Often small and medium capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund's volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund's performance. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC or any other government agency.

[1] Invesco PowerShares Capital Management LLC (the "Adviser") has agreed to waive fees and/or pay Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, brokerage commissions and other trading expenses, sub-licensing fees, offering costs, taxes and extraordinary expenses) from exceeding 0.60% of the Fund's average daily net assets per year (the "Expense Cap") until at least August 31, 2012, and neither the Adviser nor the Fund can discontinue the agreement prior to its expiration. The expenses borne by the Adviser are subject to recapture by the Adviser for up to three years from the date the fee or expense was borne by the Adviser, but no recapture payment will be made by the Fund if it would result in the Fund exceeding its Expense Cap.

Investment Strategy, Heading	rr_StrategyHeading	Principal Investment Strategies
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 90% of its total assets in common stocks that comprise the Underlying Intellidex. As of June 30, 2011, the Underlying Intellidex was composed of 100 U.S. stocks that NYSE Arca, Inc. ("NYSE Arca" or the "Intellidex Provider"), strictly in accordance with its existing guidelines and mandated procedures, included pursuant to a proprietary method. The Underlying Intellidex selection methodology seeks to identify and select companies from the U.S. marketplace with superior risk-return profiles. As of June 30, 2011, the Underlying Intellidex included common stocks of companies with a market capitalization range of between approximately $363 million and $206 billion. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Intellidex reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.

Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. Market Risk. Securities in the Underlying Intellidex are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Intellidex. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock of an issuer may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock of an issuer in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Intellidex may be composed of issuers in a single industry or sector of the economy. If the Fund is focused in an industry or sector, it may present more risks than if it were broadly diversified over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries of the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Intellidex for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Intellidex, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Intellidex. In addition, the performance of the Fund and the Underlying Intellidex may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Intellidex resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Intellidex. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Intellidex, even if that security generally is underperforming. Medium Capitalization Company Risk. Investing in securities of medium capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Often medium capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC or any other government agency.

PowerShares Dynamic Utilities Portfolio (Prospectus Summary) | PowerShares Dynamic Utilities Portfolio

PowerShares Dynamic Utilities Portfolio

Investment Objective

The PowerShares Dynamic Utilities Portfolio (the "Fund") seeks investment
results that generally correspond (before fees and expenses) to the price and
yield of the Dynamic Utilities IntellidexSM Index (the "Underlying Intellidex").

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors may pay brokerage commissions on their
purchases and sales of Shares, which are not reflected in the table or the
example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		PowerShares Dynamic Utilities Portfolio
Management Fees		0.50%
Other Expenses		0.39%
Total Annual Fund Operating Expenses		0.89%
Fee Waivers and Expense Assumption	[1]	0.26%
Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption	[1]	0.63%

Example

This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. This example assumes that you invest
$10,000 in the Fund for the time periods indicated and then sell all of your
Shares at the end of those periods. The example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. The cost under the one year example is equal to the Total
Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the
first year and the Total Annual Fund Operating Expenses thereafter. This example
does not include the brokerage commissions that investors may pay to buy and sell
Shares of the Fund.

Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Expense Example (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
PowerShares Dynamic Utilities Portfolio	64	258	468	1,072

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover was 68% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 80% of its total assets in common stocks
of utilities companies. The Fund generally will invest at least 90% of its total
assets in common stocks that comprise the Underlying Intellidex. As of June 30,
2011, the Underlying Intellidex was comprised of stocks of 60 U.S. utilities
companies. These companies are principally engaged in providing either energy,
water, natural gas or telecommunications services. These companies may include
companies that generate and supply electricity, including electricity
wholesalers; distribute natural gas to customers; provide water to customers, as
well as deal with associated wastewater; and provide land line or wireless
telephone services. Strictly in accordance with its existing guidelines and
mandated procedures, NYSE Arca, Inc. ("NYSE Arca" or the "Intellidex Provider")
includes stocks principally on the basis of their capital appreciation potential
that it identifies pursuant to a proprietary Intellidex methodology. As of June
30, 2011, the Underlying Intellidex included common stocks of companies with a
market capitalization range of between approximately $394 million and $186
billion.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying
Intellidex reflects a concentration in that industry or group of industries. The
Fund will not otherwise concentrate its investments in securities of issuers in
any one industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Energy Sector Risk. Changes in worldwide energy prices, exploration and
production spending may adversely affect companies in the energy sector. Changes
in government regulation, world events and economic conditions also affect these
companies. In addition, these companies are at risk of civil liability from
accidents resulting in injury, loss of life or property, pollution or other
environmental damage claims and risk of loss from terrorism and natural
disasters. Commodity price volatility, changes in exchange rates, imposition of
import controls, increased competition, depletion of resources, development of
alternative energy sources, technological developments and labor relations also
could adversely affect companies in this sector.

Utilities Sector Risk. Issuers in the utility sector are subject to a variety of
factors that may adversely affect their business or operations, including high
interest costs associated with capital construction and improvement programs;
difficulty in raising adequate capital on reasonable terms in periods of high
inflation and unsettled capital markets; governmental regulation of rates the
issuer can charge to customers; costs associated with compliance, and adjusting
to changes to, environmental and other regulations; effects of economic
slowdowns and surplus capacity; increased competition from other providers of
utility services; inexperience with, and potential losses resulting from, a
developing deregulatory environment; costs associated with the reduced
availability of certain types of fuel, occasionally reduced availability and
high costs of natural gas for resale, and the effects of energy conservation
policies; effects of a national energy policy and lengthy delays, and greatly
increased costs and other problems, associated with the design, construction,
licensing, regulation and operation of nuclear facilities for electric
generation, including, among other considerations, the problems associated with
the use of radioactive materials and the disposal of radioactive wastes;
technological innovations that may render existing plants, equipment or products
obsolete; difficulty in obtaining regulatory approval of new technologies; lack
of compatibility of telecommunications equipment; and potential impact of
terrorist activities on the utility industry and its customers and the impact of
natural or man-made disasters. Additionally, nuclear facility operators may face
greater regulatory scrutiny as a result of the disaster at the Fukushima I
Nuclear Power Plant in Japan, which may lead to reduced profits and investor
interest for these type of issuers. Issuers in the utilities sector also may be
subject to regulation by various governmental authorities and may be affected by
the imposition of special tariffs and changes in tax laws, regulatory policies
and accounting standards.

Market Risk. Securities in the Underlying Intellidex are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Intellidex.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets and disruption in the creation/redemption process of the Fund.
Any of these factors may lead to the Shares trading at a premium or discount to
the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or debt
instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Intellidex is
comprised of issuers in a single industry or sector of the economy. By focusing
in an industry or sector, the Fund faces more risks than if it were diversified
broadly over numerous industries and sectors of the economy. At times, such
industry or group of industries may be out of favor and underperform other industries
or the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Intellidex for a number of reasons. For example, the Fund incurs
operating expenses not applicable to the Underlying Intellidex, and incurs costs
in buying and selling securities, especially when rebalancing the Fund's
securities holdings to reflect changes in the composition of the Underlying
Intellidex. In addition, the performance of the Fund and the Underlying
Intellidex may vary due to asset valuation differences and differences between
the Fund's portfolio and the Underlying Intellidex resulting from legal
restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Intellidex.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Intellidex, even if that
security generally is underperforming.

Small and Medium Capitalization Company Risk. Investing in securities of small
and medium capitalization companies involves greater risk than customarily is
associated with investing in larger, more established companies. These
companies' securities may be more volatile and less liquid than those of more
established companies. These securities may have returns that vary, sometimes
significantly, from the overall securities market. Often small and medium
capitalization companies and the industries in which they focus are still
evolving and, as a result, they may be more sensitive to changing market
conditions.

Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater
portion of its assets in securities of individual issuers than a diversified
fund. As a result, changes in the market value of a single investment could
cause greater fluctuations in Share price than would occur in a diversified
fund. This may increase the Fund's volatility and cause the performance of a
relatively small number of issuers to have a greater impact on the Fund's
performance.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC
or any other government agency.

Performance

The bar chart below shows how the Fund has performed. The table below the bar
chart shows the Fund's average annual total returns (before and after taxes).
The bar chart and table provide an indication of the risks of investing in the
Fund by showing how the Fund's total return has varied from year to year and by
showing how the Fund's average annual total returns compared with a broad
measure of market performance. The Fund's performance reflects fee waivers, if
any, absent which, performance would have been lower. Although the information
shown in the bar chart and the table gives you some idea of the risks involved
in investing in the Fund, the Fund's past performance (before and after taxes)
is not necessarily indicative of how the Fund will perform in the future.

[1] Invesco PowerShares Capital Management LLC (the "Adviser") has agreed to waive fees and/or pay Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, brokerage commissions and other trading expenses, sub-licensing fees, offering costs, taxes and extraordinary expenses) from exceeding 0.60% of the Fund's average daily net assets per year (the "Expense Cap") until at least August 31, 2012, and neither the Adviser nor the Fund can discontinue the agreement prior to its expiration. The expenses borne by the Adviser are subject to recapture by the Adviser for up to three years from the date the fee or expense was borne by the Adviser, but no recapture payment will be made by the Fund if it would result in the Fund exceeding its Expense Cap.

Investment Strategy, Heading	rr_StrategyHeading	Principal Investment Strategies
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 80% of its total assets in common stocks of financial services companies. The Fund generally will invest at least 90% of its total assets in common stocks that comprise the Underlying Intellidex. As of June 30, 2011, the Underlying Intellidex was comprised of stocks of 60 U.S. financial services companies. These companies are principally engaged in the business of providing services and products, including banking, investment services, insurance and real estate finance services. Strictly in accordance with its existing guidelines and mandated procedures, NYSE Arca, Inc. ("NYSE Arca" or the "Intellidex Provider") includes stocks principally on the basis of their capital appreciation potential that it identifies pursuant to a proprietary Intellidex methodology. As of June 30, 2011, the Underlying Intellidex included common stocks of companies with a market capitalization range of between $310 million and $31 billion. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Intellidex reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Investment Strategy, Portfolio Concentration	rr_StrategyPortfolioConcentration	The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Intellidex reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. Financial Services Sector Risk. The Fund may be susceptible to adverse economic or regulatory occurrences affecting the financial services sector. Investing in the financial services sector involves risks, including the following: financial services companies are subject to extensive government regulation and, as a result, their profitability may be affected by new regulations or regulatory interpretations; unstable interest rates can have a disproportionate effect on the financial services sector; financial services companies whose securities the Fund may purchase may themselves have concentrated portfolios, which makes them vulnerable to economic conditions that affect that sector; and financial services companies have been affected by increased competition, which could adversely affect the profitability or viability of such companies. Market Risk. Securities in the Underlying Intellidex are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Intellidex. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Intellidex is comprised of issuers in a single industry or sector of the economy. By focusing in an industry or sector, the Fund faces more risks than if it were diversified broadly over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries or the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Intellidex for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Intellidex, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Intellidex. In addition, the performance of the Fund and the Underlying Intellidex may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Intellidex resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Intellidex. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Intellidex, even if that security generally is underperforming. Small and Medium Capitalization Company Risk. Investing in securities of small and medium capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Often small and medium capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC or any other government agency.

[1] Acquired Fund Fees and Expenses are indirect fees and expenses that the Fund incurs from investing in the shares of other investment companies. Please note that the amount of Total Annual Fund Operating Expenses shown in the above table may differ from the ratio of expenses prior to waivers and/or recapture to average net assets included in the "Financial Highlights" section of this Prospectus, which reflects the operating expenses of the Fund and does not include indirect expenses such as Acquired Fund Fees and Expenses.

[2] Invesco PowerShares Capital Management LLC (the "Adviser") has agreed to waive fees and/or pay Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, brokerage commissions and other trading expenses, sub-licensing fees, offering costs, taxes and extraordinary expenses) from exceeding 0.60% of the Fund's average daily net assets per year (the "Expense Cap") until at least August 31, 2012, and neither the Adviser nor the Fund can discontinue the agreement prior to its expiration. The expenses borne by the Adviser are subject to recapture by the Adviser for up to three years from the date the fee or expense was borne by the Adviser, but no recapture payment will be made by the Fund if it would result in the Fund exceeding its Expense Cap.

PowerShares Fundamental Pure Mid Value Portfolio

Investment Objective

The PowerShares Fundamental Pure Mid Value Portfolio (the "Fund") seeks
investment results that generally correspond (before fees and expenses) to
the price and yield of the RAFI® Fundamental Mid Value Index (the "Underlying
Index").

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors may pay brokerage commissions on their
purchases and sales of Shares, which are not reflected in the table or the
example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		PowerShares Fundamental Pure Mid Value Portfolio
Management Fees		0.29%
Other Expenses		0.62%
Total Annual Fund Operating Expenses		0.91%
Fee Waivers and Expense Assumption	[1]	0.28%
Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption	[1]	0.63%

Example

This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. This example assumes that you invest
$10,000 in the Fund for the time periods indicated and then sell all of your
Shares at the end of those periods. The example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. The cost under the one year example is equal to the Total
Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in
the first year and the Total Annual Fund Operating Expenses thereafter. This
example does not include the brokerage commissions that investors may pay to buy
and sell Shares of the Fund.

Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Expense Example (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
PowerShares Fundamental Pure Mid Value Portfolio	64	262	476	1,094

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Shares are held in a taxable account. These costs, which are
not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the fiscal year ended April 30, 2011, the
Fund's portfolio turnover rate was 65% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 90% of its total assets in the component
securities that comprise the Underlying Index. The Underlying Index is comprised
of common stocks of "mid value" U.S. companies (including real estate investment
trusts ("REITs")) that Research Affiliates, LLC ("RAFI Affiliates" or the "Index
Provider") classifies based on its Fundamental Index® methodology. Strictly in
accordance with its existing guidelines and mandated procedures, the Index
Provider identifies the common stocks for inclusion in the Underlying Index from
a universe of the 2,500 largest U.S. companies. The use of the word
"Fundamental" in the Fund's name reflects the fact that, in identifying the
common stocks, the Index Provider uses fundamental measures of company size,
rather than market capitalization (company share price multiplied by number of
shares outstanding). The Index Provider uses the following fundamental measures
to include common stocks in the Underlying Index: book value, income, sales and
dividends. It then calculates a composite fundamental weight for each common
stock by equally weighting the above four fundamental measures. The Index
Provider then ranks each common stock by its fundamental weight and, based on
this ranking, divides the common stocks into three size groups: "large," "mid"
and "small." The common stocks it ranks in the top 70% of the eligible universe
by fundamental weight comprise the "large" size group, the next 20% comprise the
"mid" size group, and the final 10% comprise the "small" size group. The Index
Provider further divides the "mid" size group into "growth," "core" or "value"
subsets based on the Fundamental Index® methodology style score, which uses a
combination of fundamental growth rates and fundamental valuation ratios. The
Underlying Index is composed only of those common stocks that the Index Provider
classifies as both "mid" and "value." The Fund generally will invest at least
80% of its total assets in common stocks of "fundamentally mid" companies. The
Fund considers "fundamentally mid" companies to be those companies that comprise
the Underlying Index.

The use of the word "Pure" in the Fund's name reflects that, in selecting
securities for the Underlying Index, the Index Provider includes only those
securities that it has classified as "value." Although "value" funds also could
include some stocks that, based on their classification, would be considered
"growth" or "core," the Underlying Index contains only those stocks that the
Index Provider classifies as pure "value" stocks. The Fund generally will invest
in all of the securities comprising its Underlying Index in proportion to their
weightings in the Underlying Index.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying Index
reflects a concentration in that industry or group of industries. The Fund will
not otherwise concentrate its investments in securities of issuers in any one
industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

"Fundamentally Mid" Company Risk. Investing in common stocks of "fundamentally
mid" companies involves greater risk than customarily is associated with
investing in larger, more established companies. These companies' common stocks
may be more volatile and less liquid than those of more established companies.
These common stocks may have returns that vary, sometimes significantly, from
the overall stock market. Often "fundamentally mid" companies and the industries
in which they focus are still evolving and, as a result, they may be more
sensitive to changing market conditions.

REIT Risk. Although the Fund will not invest in real estate directly, the REITs
in which the Fund invests are subject to risks inherent in the direct ownership
of real estate. These risks include, but are not limited to, a possible lack of
mortgage funds and associated interest rate risks, overbuilding, property
vacancies, increases in property taxes and operating expenses, changes in zoning
laws, losses due to environmental damages and changes in neighborhood values and
appeal to purchasers.

Value Risk. "Value" securities are subject to the risk that the valuations never
improve or that the returns on "value" securities are less than returns on other
styles of investing or the overall stock market. Thus, the value of the Fund's
investments will vary and at times may be lower or higher than that of other
types of investments.

Market Risk. Securities in the Underlying Index are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Index.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets, and disruption in the creation/redemption process of the
Fund. Any of these factors may lead to the Shares trading at a premium or
discount to the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or debt
instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Index may be
comprised of issuers in a single industry or sector of the economy. If the Fund
is focused in an industry or sector, it may present more risks than if it were
diversified broadly over numerous industries and sectors of the economy. At
times, such industry or group of industries may be out of favor and underperform
other industries or the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Index for a number of reasons. For example, the Fund incurs operating
expenses not applicable to the Underlying Index, and incurs costs in buying and
selling securities, especially when rebalancing the Fund's securities holdings
to reflect changes in the composition of the Underlying Index. In addition, the
performance of the Fund and the Underlying Index may vary due to asset valuation
differences and differences between the Fund's portfolio and the Underlying
Index resulting from legal restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Index.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Index, even if that
security generally is underperforming.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the
Federal Deposit Insurance Corporation or any other government agency.

Performance

The bar chart below shows how the Fund has performed. The table below the bar
chart shows the Fund's average annual total returns (before and after taxes).
The bar chart and table provide an indication of the risks of investing in the
Fund by showing how the Fund's total return has varied from year to year and by
showing how the Fund's average annual total returns compared with a broad
measure of market performance. The Fund's performance reflects fee waivers, if
any, absent which, performance would have been lower. Although the information
shown in the bar chart and the table gives you some idea of the risks involved
in investing in the Fund, the Fund's past performance (before and after taxes)
is not necessarily indicative of how the Fund will perform in the future.

[1] Invesco PowerShares Capital Management LLC (the "Adviser") has agreed to waive fees and/or pay Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, brokerage commissions and other trading expenses, offering costs, taxes and extraordinary expenses) from exceeding 0.39% of the Fund's average daily net assets per year (the "Expense Cap") until at least August 31, 2012, and neither the Adviser nor the Fund can discontinue the agreement prior to its expiration. The expenses borne by the Adviser are subject to recapture by the Adviser for up to three years from the date the fee or expense was borne by the Adviser, but no recapture payment will be made by the Fund if it would result in the Fund exceeding its Expense Cap.

[1] Prior to June 16, 2011, the Fund sought to replicate, before fees and expenses, the performance of an index called the "Dynamic Mid Cap Value IntellidexSM Index." "1 Year," "5 Years" and "Since Inception" performance for the RAFI® Fundamental Mid Value Index is not available because the Index did not commence calculation and publication until April 15, 2011.

Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. Internet Software and Services Sector Risk. Competitive pressures, such as technological developments, fixed-rate pricing and the ability to attract and retain skilled employees, can significantly affect the internet software and services sector. Changing domestic and international demand, research and development costs, availability and price of components and product obsolescence also can affect profitability of companies in this sector. Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Index is comprised of issuers in a single industry or sector of the economy. By focusing in an industry or sector, the Fund faces more risks than if it were diversified broadly over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries or the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Index resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming. Small and Medium Capitalization Company Risk. Investing in securities of small and medium capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Often small and medium capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. Large Capitalization Company Risk. Companies with large market capitalizations may go in and out of favor based on market and economic conditions. Although larger companies tend to be less volatile than companies with smaller market capitalizations, returns on investments in securities of large capitalization U.S. companies could trail the returns on investments in securities of smaller companies. Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund's volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund's performance. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC or any other government agency.

PowerShares Dynamic Basic Materials Sector Portfolio (Prospectus Summary) | PowerShares Dynamic Basic Materials Sector Portfolio

PowerShares Dynamic Basic Materials Sector Portfolio

Investment Objective

The PowerShares Dynamic Basic Materials Sector Portfolio (the "Fund") seeks
investment results that generally correspond (before fees and expenses) to the
price and yield of the Dynamic Basic Materials Sector IntellidexSM Index (the
"Underlying Intellidex").

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors may pay brokerage commissions on their
purchases and sales of Shares, which are not reflected in the table or the
example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		PowerShares Dynamic Basic Materials Sector Portfolio
Management Fees		0.50%
Other Expenses		0.29%
Total Annual Fund Operating Expenses		0.79%
Fee Waivers and Expense Assumption	[1]	0.14%
Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption	[1]	0.65%

Example

This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. This example assumes that you invest
$10,000 in the Fund for the time periods indicated and then sell all of your
Shares at the end of those periods. The example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. The cost under the one year example is equal to the Total
Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the
first year and the Total Annual Fund Operating Expenses thereafter. This example
does not include the brokerage commissions that investors may pay to buy and sell
Shares of the Fund.

Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Expense Example (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
PowerShares Dynamic Basic Materials Sector Portfolio	66	238	425	965

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover was 28% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 80% of its total assets in common stocks
of basic materials companies. The Fund generally will invest at least 90% of its
total assets in common stocks that comprise the Underlying Intellidex. As of
June 30, 2011, the Underlying Intellidex was comprised of stocks of 60 U.S.
basic materials companies. These companies are principally engaged in the
business of producing raw materials, including paper or wood products,
chemicals, construction materials, and mining and metals. Strictly in accordance
with its existing guidelines and mandated procedures, NYSE Arca, Inc. ("NYSE
Arca" or the "Intellidex Provider") includes stocks principally on the basis of
their capital appreciation potential that it identifies pursuant to a
proprietary Intellidex methodology. As of June 30, 2011, the Underlying
Intellidex included common stocks of companies with a market capitalization
range of between $319 million and $50 billion.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying
Intellidex reflects a concentration in that industry or group of industries. The
Fund will not otherwise concentrate its investments in securities of issuers in
any one industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Basic Materials Sector Risk. Changes in world events, political and economic
conditions, energy conservation, environmental policies, commodity price
volatility, changes in exchange rates, imposition of import controls, increased
competition, depletion of resources and labor relations may adversely affect the
companies engaged in the production and distribution of basic materials.

Market Risk. Securities in the Underlying Intellidex are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Intellidex.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets and disruption in the creation/redemption process of the Fund.
Any of these factors may lead to the Shares trading at a premium or discount to
the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or debt
instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Intellidex is
comprised of issuers in a single industry or sector of the economy. By focusing
in an industry or sector, the Fund faces more risks than if it were diversified
broadly over numerous industries and sectors of the economy. At times, such
industry or group of industries may be out of favor and underperform other
industries or the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Intellidex for a number of reasons. For example, the Fund incurs
operating expenses not applicable to the Underlying Intellidex, and incurs costs
in buying and selling securities, especially when rebalancing the Fund's
securities holdings to reflect changes in the composition of the Underlying
Intellidex. In addition, the performance of the Fund and the Underlying
Intellidex may vary due to asset valuation differences and differences between
the Fund's portfolio and the Underlying Intellidex resulting from legal
restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Intellidex.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Intellidex, even if that
security generally is underperforming.

Small and Medium Capitalization Company Risk. Investing in securities of small
and medium capitalization companies involves greater risk than customarily is
associated with investing in larger, more established companies. These
companies' securities may be more volatile and less liquid than those of more
established companies. These securities may have returns that vary, sometimes
significantly, from the overall securities market. Often small and medium
capitalization companies and the industries in which they focus are still
evolving and, as a result, they may be more sensitive to changing market
conditions.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC
or any other government agency.

The expenses borne by the Adviser are subject to recapture by the Adviser for up to three years from the date the fee or expense was borne by the Adviser, but no recapture payment will be made by the Fund if it would result in the Fund exceeding its Expense Cap.

PowerShares Dynamic Technology Sector Portfolio (Prospectus Summary) | PowerShares Dynamic Technology Sector Portfolio

PowerShares Dynamic Technology Sector Portfolio

Investment Objective

The PowerShares Dynamic Technology Sector Portfolio (the "Fund") seeks
investment results that generally correspond (before fees and expenses) to the
price and yield of the Dynamic Technology Sector IntellidexSM Index (the
"Underlying Intellidex").

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors may pay brokerage commissions on their
purchases and sales of Shares, which are not reflected in the table or the
example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		PowerShares Dynamic Technology Sector Portfolio
Management Fees		0.50%
Other Expenses		0.41%
Total Annual Fund Operating Expenses		0.91%
Fee Waivers and Expense Assumption	[1]	0.26%
Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption	[1]	0.65%

Example

This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. This example assumes that you invest
$10,000 in the Fund for the time periods indicated and then sell all of your
Shares at the end of those periods. The example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. The cost under the one year example is equal to the Total
Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the
first year and the Total Annual Fund Operating Expenses thereafter. This example
does not include the brokerage commissions that investors may pay to buy and sell
Shares of the Fund.

Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Expense Example (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
PowerShares Dynamic Technology Sector Portfolio	66	264	478	1,096

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Fund Shares are held in a taxable account. These costs, which
are not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover was 67% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 80% of its total assets in common stocks
of technology companies. The Fund generally will invest at least 90% of its
total assets in common stocks that comprise the Underlying Intellidex. As of
June 30, 2011, the Underlying Intellidex was comprised of stocks of 60 U.S.
technology companies. These companies are principally engaged in the business of
providing technology-related products and services, including computer hardware
and software, Internet, electronics and semiconductors, and communication
technologies. Strictly in accordance with its existing guidelines and mandated
procedures, NYSE Arca, Inc. ("NYSE Arca" or the "Intellidex Provider") includes
stocks principally on the basis of their capital appreciation potential that it
identifies pursuant to a proprietary Intellidex methodology. As of June 30,
2011, the Underlying Intellidex included common stocks of companies with a
market capitalization range of between $355 million and $205 billion.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying
Intellidex reflects a concentration in that industry or group of industries. The
Fund will not otherwise concentrate its investments in securities of issuers in
any one industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Technology Sector Risk. Factors such as the failure to obtain, or delays in
obtaining, financing or regulatory approval, intense competition, product
compatibility, consumer preferences, corporate capital expenditure, rapid
obsolescence, competition from alternative technologies, and research and
development of new products may significantly affect the market value of
securities of issuers in the technology sector.

Market Risk. Securities in the Underlying Intellidex are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Intellidex.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets and disruption in the creation/redemption process of the Fund.
Any of these factors may lead to the Shares trading at a premium or discount to
the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or debt
instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Intellidex is
comprised of issuers in a single industry or sector of the economy. By focusing
in an industry or sector, the Fund faces more risks than if it were diversified
broadly over numerous industries and sectors of the economy. At times, such
industry or group of industries may be out of favor and underperform other
industries or the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Intellidex for a number of reasons. For example, the Fund incurs
operating expenses not applicable to the Underlying Intellidex, and incurs costs
in buying and selling securities, especially when rebalancing the Fund's
securities holdings to reflect changes in the composition of the Underlying
Intellidex. In addition, the performance of the Fund and the Underlying
Intellidex may vary due to asset valuation differences and differences between
the Fund's portfolio and the Underlying Intellidex resulting from legal
restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Intellidex.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Intellidex, even if that
security generally is underperforming.

Small and Medium Capitalization Company Risk. Investing in securities of small
and medium capitalization companies involves greater risk than customarily is
associated with investing in larger, more established companies. These
companies' securities may be more volatile and less liquid than those of more
established companies. These securities may have returns that vary, sometimes
significantly, from the overall securities market. Often small and medium
capitalization companies and the industries in which they focus are still
evolving and, as a result, they may be more sensitive to changing market
conditions.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC
or any other government agency.

PowerShares Fundamental Pure Large Core Portfolio	66	281	514	1,182

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and
sells securities (or "turns over" its portfolio). A higher portfolio turnover
will cause the Fund to incur additional transaction costs and may result in
higher taxes when Shares are held in a taxable account. These costs, which are
not reflected in Total Annual Fund Operating Expenses or in the example, may
affect the Fund's performance. During the fiscal year ended April 30, 2011, the
Fund's portfolio turnover rate was 41% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 90% of its total assets in the component
securities that comprise the Underlying Index. The Underlying Index is comprised
of common stocks of "large core" U.S. companies (including real estate
investment trusts ("REITs")) that Research Affiliates, LLC ("RAFI Affiliates" or
the "Index Provider") classifies based on its Fundamental Index® methodology.
Strictly in accordance with its existing guidelines and mandated procedures, the
Index Provider identifies the common stocks for inclusion in the Underlying
Index from a universe of the 2,500 largest U.S. companies. The use of the word
"Fundamental" in the Fund's name reflects the fact that, in identifying common
stocks, the Index Provider uses fundamental measures of company size, rather
than market capitalization (company share price multiplied by number of shares
outstanding). The Index Provider uses the following fundamental measures to
include common stocks in the Underlying Index: book value, income, sales and
dividends. It then calculates a composite fundamental weight for each common
stock by equally weighting the above four fundamental measures. The Index
Provider then ranks each common stock by its fundamental weight and, based on
this ranking, divides the common stocks into three size groups: "large," "mid"
and "small." The common stocks it ranks in the top 70% of the eligible universe
by fundamental weight comprise the "large" size group, the next 20% comprise the
"mid" size group, and the final 10% comprise the "small" size group. The Index
Provider further divides the "large" size group into "growth," "core" or "value"
subsets based on the Fundamental Index® methodology style score, which uses a
combination of fundamental growth rates and fundamental valuation ratios. The
Underlying Index is composed only of those common stocks that the Index Provider
classifies as both "large" and "core." The Fund generally will invest at least
80% of its total assets in common stocks of "fundamentally large" companies. The
Fund considers "fundamentally large" companies to be those companies that
comprise the Underlying Index.

The use of the word "Pure" in the Fund's name reflects that, in selecting
securities for the Underlying Index, the Index Provider includes only those
securities that it has classified as "core." Although "core" funds also could
include some stocks that, based on their classification, would be considered
"growth" or "value," the Underlying Index contains only those stocks that the
Index Provider classifies as pure "core" stocks. The Fund generally will invest
in all of the securities comprising its Underlying Index in proportion to their
weightings in the Underlying Index.

Concentration Policy. The Fund will concentrate its investments (i.e., invest
25% or more of the value of its total assets) in securities of issuers in any
one industry or group of industries only to the extent that the Underlying Index
reflects a concentration in that industry or group of industries. The Fund will
not otherwise concentrate its investments in securities of issuers in any one
industry or group of industries.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

Core Risk. The returns on "core" securities may or may not move in tandem with
the returns on other styles of investing or the overall stock market. Thus, the
value of the Fund's investments will vary and at times may be lower or higher
than that of other types of investments.

"Fundamentally Large" Company Risk. Returns on investments in common stocks of
"fundamentally large" U.S. companies could trail the returns on investments in
common stocks of smaller companies or other large companies based on market
capitalization.

REIT Risk. Although the Fund will not invest in real estate directly, the REITs
in which the Fund invests are subject to risks inherent in the direct ownership
of real estate. These risks include, but are not limited to, a possible lack of
mortgage funds and associated interest rate risks, overbuilding, property
vacancies, increases in property taxes and operating expenses, changes in zoning
laws, losses due to environmental damages and changes in neighborhood values and
appeal to purchasers.

Market Risk. Securities in the Underlying Index are subject to market
fluctuations. You should anticipate that the value of the Shares will decline,
more or less, in correlation with any decline in value of the securities in the
Underlying Index.

Market Trading Risk. The Fund faces numerous market trading risks, including the
potential lack of an active market for the Shares, losses from trading in
secondary markets, and disruption in the creation/redemption process of the
Fund. Any of these factors may lead to the Shares trading at a premium or
discount to the Fund's net asset value ("NAV").

Equity Risk. Equity risk is the risk that the value of the securities the Fund
holds will fall due to general market and economic conditions, perceptions
regarding the industries in which the issuers of securities the Fund holds
participate or factors relating to specific companies in which the Fund invests.
For example, an adverse event, such as an unfavorable earnings report, may
depress the value of equity securities the Fund holds; the price of common stock
may be particularly sensitive to general movements in the stock market; or a
drop in the stock market may depress the price of most or all of the common
stocks and other equity securities the Fund holds. In addition, common stock in
the Fund's portfolio may decline in price if the issuer fails to make
anticipated dividend payments because, among other reasons, the issuer of the
security experiences a decline in its financial condition. Common stock is
subordinated to preferred stocks, bonds and other debt instruments in a
company's capital structure, in terms of priority to corporate income, and
therefore will be subject to greater dividend risk than preferred stocks or debt
instruments of such issuers.

Concentration Risk. A significant percentage of the Underlying Index may be
comprised of issuers in a single industry or sector of the economy. If the Fund
is focused in an industry or sector, it may present more risks than if it were
diversified broadly over numerous industries and sectors of the economy. At
times, such industry or group of industries may be out of favor and underperform
other industries or the market as a whole.

Non-Correlation Risk. The Fund's return may not match the return of the
Underlying Index for a number of reasons. For example, the Fund incurs operating
expenses not applicable to the Underlying Index, and incurs costs in buying and
selling securities, especially when rebalancing the Fund's securities holdings
to reflect changes in the composition of the Underlying Index. In addition, the
performance of the Fund and the Underlying Index may vary due to asset valuation
differences and differences between the Fund's portfolio and the Underlying
Index resulting from legal restrictions, cost or liquidity constraints.

Index Risk. Unlike many investment companies, the Fund does not utilize an
investing strategy that seeks returns in excess of the Underlying Index.
Therefore, it would not necessarily buy or sell a security unless that security
is added or removed, respectively, from the Underlying Index, even if that
security generally is underperforming.

Issuer-Specific Changes. The value of an individual security or particular type
of security may be more volatile than the market as a whole and may perform
differently from the value of the market as a whole.

The Shares will change in value, and you could lose money by investing in the
Fund. The Fund may not achieve its investment objective. An investment in the
Fund is not a deposit with a bank and is not insured or guaranteed by the
Federal Deposit Insurance Corporation or any other government agency.

[1] Invesco PowerShares Capital Management LLC (the "Adviser") has agreed to waive fees and/or pay Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, brokerage commissions and other trading expenses, offering costs, taxes and extraordinary expenses) from exceeding 0.39% of the Fund's average daily net assets per year (the "Expense Cap") until at least August 31, 2012, and neither the Adviser nor the Fund can discontinue the agreement prior to its expiration. The expenses borne by the Adviser are subject to recapture by the Adviser for up to three years from the date the fee or expense was borne by the Adviser, but no recapture payment will be made by the Fund if it would result in the Fund exceeding its Expense Cap.

[1] Prior to June 16, 2011, the Fund sought to replicate, before fees and expenses, the performance of an index called the "Dynamic Large Cap IntellidexSM Index." "1 Year" and "Since Inception" performance for the RAFI® Fundamental Large Core Index is not available because the Index did not commence calculation and publication until April 15, 2011.

Portfolio Turnover	rr_PortfolioTurnoverTextBlock	The Fund pays transaction costs, such as commissions, when it purchases and sells securities (or "turns over" its portfolio). A higher portfolio turnover will cause the Fund to incur additional transaction costs and may result in higher taxes when Fund Shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the example, may affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover was 48% of the average value of its portfolio.

Expense Example, Narrative	rr_ExpenseExampleNarrativeTextBlock	This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. This example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your Shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The cost under the one year example is equal to the Total Annual Fund Operating Expenses After Fee Waivers and Expense Assumption in the first year and the Total Annual Fund Operating Expenses thereafter. This example does not include the brokerage commissions that investors may pay to buy and sell Shares of the Fund.

Investment Strategy, Heading	rr_StrategyHeading	Principal Investment Strategies
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 80% of its total assets in common stocks of industrial companies. The Fund generally will invest at least 90% of its total assets in common stocks that comprise the Underlying Intellidex. As of June 30, 2011, the Underlying Intellidex was comprised of stocks of 60 U.S. industrial companies. These companies are principally engaged in the business of providing industrial products and services, including engineering, heavy machinery, construction, electrical equipment, aerospace and defense and general manufacturing. Strictly in accordance with its existing guidelines and mandated procedures, NYSE Arca, Inc. ("NYSE Arca" or the "Intellidex Provider") includes stocks principally on the basis of their capital appreciation potential that it identifies pursuant to a proprietary Intellidex methodology. As of June 30, 2011, the Underlying Intellidex included common stocks of companies with a market capitalization range of between $344 million and $69 billion. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Intellidex reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Investment Strategy, Portfolio Concentration	rr_StrategyPortfolioConcentration	The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Intellidex reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. Industrials Sector Risk. Changes in government regulation, world events and economic conditions may adversely affect companies in the industrials sector. In addition, these companies are at risk for environmental damage claims. Also, commodity price volatility, changes in exchange rates, imposition of import controls, increased competition, depletion of resources, technological developments and labor relations could adversely affect the companies in this sector. Market Risk. Securities in the Underlying Intellidex are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Intellidex. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Intellidex is comprised of issuers in a single industry or sector of the economy. By focusing in an industry or sector, the Fund faces more risks than if it were diversified broadly over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries or the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Intellidex for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Intellidex, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Intellidex. In addition, the performance of the Fund and the Underlying Intellidex may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Intellidex resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Intellidex. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Intellidex, even if that security generally is underperforming. Small and Medium Capitalization Company Risk. Investing in securities of small and medium capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Often small and medium capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC or any other government agency.

The Fund generally will invest at least 90% of its total assets in common stocks that comprise the Underlying Intellidex. As of June 30, 2011, the Underlying Intellidex was composed of stocks of 30 U.S. insurance companies. These companies are engaged principally in underwriting or distributing and reselling life, health and property/casualty insurance policies. The Underlying Intellidex may include companies that provide coverage for various types of property and casualty risks; guarantee payment to a beneficiary when an insured person ceases to generate income, typically at death or retirement; or protect against financial loss resulting from medical bills and/or the financial consequences of poor health. The Underlying Intellidex also may include Insurance brokerage and reinsurance companies. Strictly in accordance with its existing guidelines and mandated procedures, the Intellidex Provider includes stocks principally on the basis of their capital appreciation potential that it identifies pursuant to a proprietary Intellidex methodology. As of June 30, 2011, the Underlying Intellidex included common stocks of companies with a market capitalization range of between approximately $499 million and $31 billion. Concentration Policy.

The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk, Narrative	rr_RiskNarrativeTextBlock	The following summarizes the principal risks of the Fund. Insurance Industry Concentration Risk. Many factors, including changes in interest rates, general economic conditions, the imposition of premium rate caps, competition and pressure to compete globally, including price and marketing competition, and other changes in government regulation or tax law, can significantly affect companies in the insurance industry. In addition, different segments of the insurance industry can be significantly affected by mortality and morbidity rates, actuarial miscalculations, environmental clean-up costs and catastrophic events such as earthquakes, hurricanes and terrorist acts, and availability and cost of reinsurance. Market Risk. Securities in the Underlying Intellidex are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Intellidex. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's net asset value ("NAV"). Equity Risk. Equity risk is the risk that the value of the securities the Fund holds will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities the Fund holds; the price of common stock may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities the Fund holds. In addition, common stock in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Concentration Risk. A significant percentage of the Underlying Intellidex is comprised of issuers in a single industry or sector of the economy. By focusing in an industry or sector, the Fund faces more risks than if it were diversified broadly over numerous industries and sectors of the economy. At times, such industry or group of industries may be out of favor and underperform other industries or the market as a whole. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Intellidex for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Intellidex, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Intellidex. In addition, the performance of the Fund and the Underlying Intellidex may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Intellidex resulting from legal restrictions, cost or liquidity constraints. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Intellidex. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Intellidex, even if that security generally is underperforming. Small and Medium Capitalization Company Risk. Investing in securities of small and medium capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Often small and medium capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund's volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund's performance. Issuer-Specific Changes. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC or any other government agency.

[1] Invesco PowerShares Capital Management LLC (the "Adviser") has agreed to waive fees and/or pay Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, brokerage commissions and other trading expenses, sub-licensing fees, offering costs, taxes and extraordinary expenses) from exceeding 0.60% of the Fund's average daily net assets per year (the "Expense Cap") until at least August 31, 2012, and neither the Adviser nor the Fund can discontinue the agreement prior to its expiration. The expenses borne by the Adviser are subject to recapture by the Adviser for up to three years from the date the fee or expense was borne by the Adviser, but no recapture payment will be made by the Fund if it would result in the Fund exceeding its Expense Cap.
