Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the Fund's most recent fiscal year, the Fund's portfolio turnover rate was 151% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is one of three funds which, together, comprise the Target Asset Allocation Funds. The Funds are designed for investors who want investment professionals to make their asset allocation decisions in light of their personal investment goals and risk tolerance. Each Fund pursues its investment objective by investing in a mix of equity and fixed-income securities appropriate for a particular type of investor. Each Fund may serve as the cornerstone of a larger investment portfolio.

The risk/return balance of each Fund depends upon the proportion of assets it allocates to different types of investments. Higher risk does not always result in higher returns. The Manager (Prudential Investments LLC) has developed an asset allocation strategy for each Fund designed to provide a mix of investment types and styles that is appropriate for investors with conservative, moderate and aggressive investment orientations.

Each Fund has a distinct investment objective and is situated differently along the risk/return spectrum, as illustrated in the following table:

[graphic]

The Target Moderate Allocation Fund may be appropriate for investors looking for a balance of long-term capital growth and current income (e.g., investors in their 50s who are saving on a regular basis for retirement and who plan to retire in their early to mid 60s). The Fund offers a diversified approach to equities for long-term growth, but will normally maintain a substantial component of fixed-income securities to provide current income and a measure of stability.

The Manager has contracted with several subadvisers to manage the assets of the Fund. Each subadviser manages a portion of the Fund's assets, focusing on a particular type and style of investing. The Manager monitors the performance of the Fund's subadvisers and allocates the Fund's assets among its subadvisers.

The Manager believes that its asset allocation strategy and multi-subadviser approach will enhance the performance of the Fund and minimize its volatility. First, the Manager has identified a select group of experienced subadvisers. Although each subadviser will focus the management of its Fund segment on a particular type and style of investing, the Manager believes that the combined efforts of several subadvisers will result in a prudently diversified Fund. Secondly, the Manager believes that, at any given time, certain investment types and styles will generate higher returns than others. Accordingly, the Manager believes that diversifying the Fund among a variety of investment types and styles will reduce volatility relative to the price movements of a single asset class.

Please see How the Funds Invest in this Prospectus for specific information on each subadviser, the Fund segments managed by each subadviser and the allocations among subadvisers as a percentage of long-term investments. The allocations among subadvisers are reviewed by the Manager periodically, and the allocations among subadvisers may be altered or adjusted by the Manager without prior notice to shareholders. Such adjustments will be reflected in an annual update to this Prospectus.

In response to market developments, the Manager may rebalance the allocation of the Fund's assets or may add or eliminate Fund segments in accordance with the Fund's investment objective and the investment policies of the Fund.

Risk [Heading]

Principal Risks of Investing in the Fund.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

All investments have risks to some degree. Please remember that an investment in the Fund is not guaranteed to achieve its investment objective; is not a deposit with a bank; is not insured, endorsed or guaranteed by the Federal Deposit Insurance Corporation or any other government agency; and is subject to investment risks, including possible loss of your original investment.

Recent Market Events. The equity and debt capital markets in the United States and internationally have experienced unprecedented volatility. This financial crisis has caused a significant decline in the value and liquidity of many securities. This environment could make identifying investment risks and opportunities especially difficult for the subadvisers. These market conditions may continue or get worse. In response to the crisis, the U.S. and other governments and the Federal Reserve and certain foreign central banks have taken steps to support financial markets. The withdrawal of this support could negatively affect the value and liquidity of certain securities. In addition, legislation recently enacted in the United States calls for changes in many aspects of financial regulation. The impact of the legislation on the markets, and the practical implications for market participants, may not be known for some time.

Risk of Increase in Expenses. Your actual cost of investing in the Fund may be higher than the expenses shown in the expense table for a variety of reasons. For example, expense ratios may be higher than those shown if average net assets decrease. Net assets are more likely to decrease and Fund expense ratios are more likely to increase when markets are volatile.

Market Risk for Common Stocks. Since the Fund invests in common stocks, there is the risk that the price of a particular stock owned by the Fund could go down. Generally, the stock price of large companies is more stable than the stock price of smaller companies, but this is not always the case. In addition to an individual stock losing value, the value of a market sector or of the equity market as a whole could go down. In addition, different parts of a market can react differently to adverse issuer, market, regulatory, political and economic developments.

Small- and Medium-Size Company Risk. The Fund invests in stocks of small-size ("small-cap") companies. In addition, each of the subadvisers that invests in stocks may from time to time invest in stocks of medium-size ("mid-cap") companies. Mid-cap companies are similar to those found in the Russell MidCap Index, a market capitalization weighted index of common stocks designed to track the performance of mid-cap companies. Small- and mid-cap companies usually offer a smaller range of products and services than larger companies. They may also have limited financial resources and may lack management depth. As a result, the prices of stocks issued by small- and mid-cap companies tend to fluctuate more than the stocks of larger, more established companies.

Style Risk. Since some of the Fund segments focus on either a growth or value style, there is the risk that a particular style may be out of favor for a period of time.

Political Developments. Political developments may adversely affect the value of the Fund's foreign securities.

Foreign Market Risk. Investing in foreign securities involves more risk than investing in securities of U.S. issuers. Foreign markets—especially emerging markets—tend to be more volatile than U.S. markets and are generally not subject to regulatory requirements comparable to those in the U.S.

Currency Risk. Changes in currency exchange rates may affect the value of foreign securities held by the Fund and the amount of income available for distribution. If a foreign currency grows weaker relative to the U.S. dollar, the value of securities denominated in that foreign currency generally decreases in terms of U.S. dollars. If the Fund does not correctly anticipate changes in exchange rates, certain hedging activities may also cause the Fund to lose money and reduce the amount of income available for distribution.

Derivatives Risk. The Fund may use derivatives including swaps, options and futures as a principal investment strategy to improve its returns or to protect its assets. When used for hedging purposes, derivatives may not fully offset or match the Fund's underlying positions and this could result in losses to the Fund that would not otherwise have occurred.

Leverage Risk. The Fund may borrow from banks or through reverse repurchase agreements and dollar rolls to take advantage of investment opportunities. This is known as using "leverage." If the Fund borrows money to purchase securities and those securities decline in value, then the value of the Fund's shares will decline faster than if the Fund were not leveraged.

Management Risk. Actively managed mutual funds are subject to management risk. The subadvisers will apply investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these techniques will produce the desired results. Additionally, the securities selected by the subadvisers may underperform the markets in general, the Fund's benchmark and other mutual funds with similar investment objectives.

Liquidity Risk. The risk that the Fund may invest to a greater degree in securities that trade in lower volumes and may make investments that may be less liquid than other investments. Also, the risk that a Fund may make investments that may become less liquid in response to market developments or adverse investor perceptions. When there is no willing buyer and investments cannot be readily sold at the desired time or price, the Fund may have to accept a lower price or may not be able to sell the security at all. An inability to sell a portfolio position can adversely affect the Fund's value or prevent the Fund from being able to take advantage of other investment opportunities.

Interest Rate Risk. Debt obligations with longer maturities typically offer higher yields, but are subject to greater price shifts as a result of interest rate changes than debt obligations with shorter maturities. The prices of debt obligations generally move in the opposite direction to that of market interest rates.

Market Risk for Debt Obligations. Debt obligations are also subject to market risk, which is the possibility that the market value of an investment may move up or down and that its movement may occur quickly or unpredictably. Market risk may affect an industry, a sector or the entire market.

Credit Risk. The debt obligations in which the Fund invests are generally subject to the risk that the issuer may be unable to make principal and interest payments when they are due. The Fund may invest in below-investment-grade securities—also known as "junk bonds"—which have a higher risk of default and tend to be less liquid than higher-rated securities. The Fund may also invest in debt obligations of foreign issuers. Investing in foreign securities presents additional risks.

Prepayment Risk. The Fund may invest in mortgage-related securities and asset-backed securities, which are subject to prepayment risk. If these securities are prepaid, the Fund may have to replace them with lower-yielding securities. Stripped mortgage-backed securities are generally more sensitive to changes in prepayment and interest rates than other mortgage-related securities.

Portfolio Turnover Risk. The length of time the Fund has held a particular security is not generally a consideration in investment decisions. Under certain market conditions, the Fund's turnover rate may be higher than that of other mutual funds. Portfolio turnover generally involves some expense to the Fund, including brokerage commissions or dealer mark-ups and other transaction costs on the sale of securities and reinvestment in other securities. These transactions may result in realization of taxable capital gains. The trading costs and tax effects associated with portfolio turnover may adversely affect the Fund's investment performance.
