Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold Fund shares.

ANNUAL FUND OPERATING EXPENSES (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		SAAT CORE MARKET STRATEGY FUND CLASS I
Management Fees		0.10%
Distribution (12b-1) Fees		none
Other Expenses		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 mutual funds. The Example assumes
that you invest $10,000 in the Fund for the time periods indicated and then
redeem 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.

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

Expense Example (USD $)	Expense Example, By Year, Column Name	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
SAAT CORE MARKET STRATEGY FUND CLASS I	Class I Shares	158	490	845	1,845

Portfolio Turnover

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 most recent fiscal year, the Fund's portfolio turnover rate was 98%
of the average value of its portfolio.

Principal Investment Strategies

The Core Market Strategy Fund invests in Underlying SEI Funds. The Underlying
SEI Funds invest, in turn, in securities in specific asset classes. Each of the
Underlying SEI Funds is managed by one or more Sub-Advisers under the
supervision of SIMC.

The Fund's assets will be invested in one or more Underlying SEI Funds that
invest primarily in U.S. and/or foreign common stocks and U.S. short-term
investment grade fixed income securities, including mortgage-backed,
asset-backed and inflation-sensitive securities. The Fund will invest to a
lesser extent in Underlying SEI Funds that invest primarily in U.S. and/or
foreign non-investment grade fixed income securities and securities of real
estate companies. SIMC manages the Fund by allocating Fund assets among a
variety of Underlying SEI Funds within the following percentage ranges:

                                                        Investment Range
Fund/Asset Class                               (Percentage of the Fund's Assets)
U.S. Equity                                                              20-70%

Principal Risks

Asset Allocation Risk -- The risk that SIMC's decisions regarding asset classes
and Underlying SEI Funds will not anticipate market trends successfully.

Below Investment Grade Securities Risk -- Fixed income securities rated below
investment grade (junk bonds) involve greater risks of default or downgrade and
are more volatile than investment grade securities.

Derivatives Risk -- An Underlying SEI Fund's use of futures, forward contracts,
options and swaps is subject to market risk, leverage risk, correlation risk and
liquidity risk. Market risk is the risk that the market value of an investment
may move up and down, sometimes rapidly and unpredictably. Leverage risk is the
risk that a small percentage of assets invested in a derivative can have a
disproportionately larger impact on the Underlying SEI Fund. Correlation risk is
the risk that changes in the value of the derivative may not correlate perfectly
with the underlying asset, rate or index. Liquidity risk is the risk that the
derivative may be difficult or impossible to sell at the time and the price that
the Underlying SEI Fund would like, which may cause the Underlying SEI Fund to
have to lower the selling price, sell other securities instead or forego an
investment opportunity. An Underlying SEI Fund's use of swaps and
over-the-counter forward contracts and options is also subject to credit risk
and valuation risk. Credit risk is the risk that the counterparty to a
derivatives contract will default or otherwise become unable to honor its
financial obligation to the Underlying SEI Fund under the contract. Valuation
risk is the risk that the derivative may be difficult to value and/or valued
incorrectly. Each of the above risks could cause an Underlying SEI Fund to lose
more than the principal amount invested in a derivative instrument.

Equity Market Risk -- The risk that prices of stocks purchased by the Underlying
SEI Funds will fall over short or extended periods of time.

Fixed Income Market Risk -- The prices of an Underlying SEI Fund's fixed income
securities respond to economic developments, particularly interest rate changes,
as well as to perceptions about the creditworthiness of individual issuers,
including governments and their agencies.

Foreign Investment/Emerging Markets Risk -- The risk that non-U.S. securities in
which the Underlying SEI Funds may invest may be subject to additional risks due
to, among other things, political, social and economic developments abroad,
currency movements, and different legal, regulatory and tax environments. These
additional risks may be heightened with respect to emerging market countries
since political turmoil and rapid changes in economic conditions are more likely
to occur in these countries.

Real Estate Industry Risk -- The risk that securities of companies principally
engaged in the real estate industry may be subject to the risks associated with
the direct ownership of real estate, including fluctuations in the value of
underlying properties and defaults by borrowers or tenants.

Short Sales Risk -- Short sales entered into by the Underlying SEI Funds expose
the Fund to the risk that an Underlying SEI Fund will be required to buy a
security sold short (also known as "covering" the short position) at a time when
the security has appreciated in value, thus resulting in a loss to the
Underlying SEI Fund and, therefore, the Fund. Reinvesting proceeds received from
short selling may create leverage which can amplify the effects of market
volatility on the Underlying SEI Fund's and, therefore, the Fund's share prices.

Small and Medium Capitalization Risk -- Smaller and medium capitalization
companies in which an Underlying SEI Fund invests may be more vulnerable to
adverse business or economic events than larger, more established companies. In
particular, small and medium capitalization companies may have limited product
lines, markets and financial resources and may depend upon a relatively small
management group. Therefore, small and medium capitalization stocks may be more
volatile than those of larger companies.

Underlying Funds Risk -- The value of an investment in the Fund is based
primarily on the performance of the Underlying SEI Funds and the allocation of
the Fund's assets among them.

Loss of money is a risk of investing in the Fund.

Performance Information

The bar chart and the performance table below provide some indication of the
risks of investing in the Fund by showing changes in the Fund's performance
from year to year and by showing how the Fund's average annual returns for 1
and 5 years, and since the Fund's inception, compared with those of a broad
measure of market performance. The Fund's past performance (before and after
taxes) is not necessarily an indication of how the Fund will perform in the
future. For current performance information, please call 1-800-DIAL-SEI.

Best Quarter: 13.02% (06/30/09)

Worst Quarter: -13.37% (12/31/08)

The Fund's Class I total return from January 1, 2011 to June 30, 2011 was 4.12%.

Average Annual Total Returns (for the periods ended December 31, 2010)

This table compares the Fund's average annual total returns for Class I Shares
to those of a broad-based index and two additional indices: the S&P 500 Index
and the MSCI EAFE Index. The S&P 500 Index and the MSCI EAFE Index, in
conjunction with the broad-based index, are used to track the broad range of
allocations the Fund makes to the Underlying SEI Funds, while each index
individually only tracks one specific allocation of the Fund. The foregoing
indices, when considered together, may provide investors with a useful
comparison of the Fund's overall performance.

After-tax returns are calculated using the historical highest individual federal
marginal income tax rates and do not reflect the impact of state and local
taxes. Your actual after-tax returns will depend on your tax situation and may
differ from those shown. After-tax returns shown are not relevant to investors
who hold their Fund shares through tax-deferred arrangements, such as 401(k)
plans or individual retirement accounts.

[1] Because the Fund incurred AFFE during the most recent fiscal year, the operating expenses in this fee table will not correlate to the expense ratio in the Fund's financial statements (or the "Financial Highlights" section in the prospectus) because the financial statements include only the direct operating expenses incurred by the Fund, not the indirect costs of investing in underlying funds.

[1] Index returns are shown from November 30, 2003.
