Managing the risk of loss does not mean preventing losses, but rather managing the Fund in a manner intended to limit the level of losses that the Fund could incur over any particular period. The Fund predominantly invests in other SEI funds, each of which has its own investment goal (the Underlying SEI Funds). The Underlying SEI Funds invest, in turn, in securities and other instruments of various asset classes. Each of the Underlying SEI Funds is managed by one or more sub-advisers (each, a Sub-Adviser and collectively, the Sub-Advisers) under the supervision of SEI Investments Management Corporation (SIMC or the Adviser), or, in certain circumstances, is managed directly by SIMC.</font> </p> <br/><p style="margin:0pt 0pt 6pt 0pt;" align="left"> <font style="font-size:10pt; font-family: Arial, Helvetica;">The Fund's assets may be diversified across Underlying SEI bond and money market funds, equity funds, real estate funds and multi-asset funds. The bond funds may consist of a wide range of investment styles that provide exposure to U.S. and/or foreign fixed income securities of varying credit quality (including junk bonds), maturity and duration. The equity funds may consist of a wide range of investment styles that provide investment exposure to U.S. and/or foreign equity securities of companies of various capitalization ranges. The real estate funds provide exposure to the equity securities of real estate companies. The multi-asset funds consist of funds that seek to achieve their investment goals by selecting investments from among a broad range of asset classes. A multi-asset fund may also adjust its allocation among asset classes over short periods of time, and therefore it may provide the Fund with a dynamic investment component. Although a multi-asset fund could consist of equity securities, bonds or real estate securities, it may also provide exposure to additional asset classes, such as commodities.</font> </p> <br/><p style="margin:0pt 0pt 6pt 0pt;" align="left"> <font style="font-size:10pt;

Leverage risk is the risk that a small percentage of assets invested in a derivative can have a disproportionately larger impact on the Fund or an Underlying SEI Fund. Correlation risk is the risk that changes in the value of a derivative instrument may not correlate perfectly with changes in the value of the derivative instrument's 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 Fund or an Underlying SEI Fund would like, which may cause the Fund or the Underlying SEI Fund to have to lower the selling price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on the Fund's or the Underlying SEI Fund's management or performance. The 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 issuer of a security or counterparty to a derivatives contract will default or otherwise become unable to honor its financial obligation to the Fund or 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 the Fund or an Underlying SEI Fund to lose more than the principal amount invested in a derivative instrument.</font><br /> </font> </p> <br/><p style="margin:0pt 0pt 6pt 0pt;" align="left"> <font style="font-size:10pt; font-family: Arial, Helvetica;"><i>Equity Market Risk</i></font> <font style="font-size:10pt; font-family: Arial, Helvetica;">&#8212; The risk that prices of stocks will fall over short or extended periods of time.</font> </p> <br/><p style="margin:0pt 0pt 6pt 0pt;" align="left"> <font style="font-size:10pt; font-family: Arial, Helvetica;"><i>Exchange-Traded Products (ETPs) Risk</i></font> <font style="font-size:10pt; font-family: Arial, Helvetica;">&#8212; The risks of owning interests of an ETP, such as an ETF, ETN or exchange-traded commodity pool, generally reflect the same risks as owning the underlying securities or other instruments that the ETP is designed to track. The shares of certain ETPs may trade at a premium or discount to their intrinsic value (i.e., the market value may differ from the net asset value of an ETP's shares). For example, supply and demand for shares of an ETF or market disruptions may cause the market price of the ETF to deviate from the value of the ETF's investments, which may be emphasized in less liquid markets. The value of an ETN may also differ from the valuation of its reference market or instrument due to changes in the issuer's credit rating. By investing in an ETP, the Fund or an Underlying SEI Fund indirectly bears the proportionate share of any fees and expenses of the ETP in addition to the fees and expenses that the Fund and its shareholders directly bear in connection with the Fund's operations. Because certain ETPs may have a significant portion of their assets exposed directly or indirectly to commodities or commodity-linked securities, developments affecting commodities may have a disproportionate impact on such ETPs and may subject the ETPs to greater volatility than investments in traditional securities.</font> </p> <br/><p style="margin:0pt 0pt 6pt 0pt;" align="left"> <font style="font-size:10pt; font-family: Arial, Helvetica;"><i>Fixed Income Market Risk</i></font> <font style="font-size:10pt; font-family: Arial, Helvetica;">&#8212; The prices of 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.

Short sales entered into by an Underlying SEI Fund expose the Fund to the risk that the 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 share price of an Underlying SEI Fund and, therefore, the Fund.

All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement. The table also should show the returns of an appropriate broad-based securities market index as defined in Instruction 5 to Item 22(b)(7) for the same periods. A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____). For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 2 -Subparagraph iv false0Performance Table Narrative40false 0truefalsetruefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalse2false truefalsedoc_Class_A_ProspectusMember_S000005819Member_index_Barclays_Capital_US_Aggregate_Bond_Index_Return_reflects_no_deduction_for_fees_expenses_or_taxesMemberhttp://www.sec.gov/CIK0001003632duration2013-03-31T00:00:002013-03-31T00:00:00falsefalseClass A Prospectusdei_DocumentInformationDocumentAxisxbrldihttp://xbrl.org/2006/xbrldick0001003632_doc_Class_A_ProspectusMemberdei_DocumentInformationDocumentAxisexplicitMemberfalsefalseSAAT CONSERVATIVE STRATEGY FUNDdei_LegalEntityAxisxbrldihttp://xbrl.org/2006/xbrldick0001003632_S000005819Memberdei_LegalEntityAxisexplicitMemberfalsefalseBarclays Capital U.S. Aggregate Bond Index Return (reflects no deduction for fees, expenses or taxes)rr_PerformanceMeasureAxisxbrldihttp://xbrl.org/2006/xbrldick0001003632_index_Barclays_Capital_US_Aggregate_Bond_Index_Return_reflects_no_deduction_for_fees_expenses_or_taxesMemberrr_PerformanceMeasureAxisexplicitMemberpureStandardhttp://www.xbrl.org/2003/instancepurexbrli0nanafalse0Barclays Capital U.S. Aggregate Bond Index Return (reflects no deduction for fees, expenses or taxes)41true 3rr_RiskReturnAbstractrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsexbrli:stringItemTypestringfalse0Risk/Return:42false 4rr_AverageAnnualReturnLabelrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalselabel1falsetruefalse00Barclays Capital U.S. Aggregate Bond Index Return (reflects no deduction for fees, expenses or taxes)falsefalsefalsexbrli:stringItemTypestringThis item represents Average Anuual Total Returns.
