Risk [Text Block] | Fixed Income Market Risk — 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. Generally, an Underlying SEI Fund's fixed income securities will decrease in value if interest rates rise and vice versa. In a low interest rate environment, risks associated with rising rates are heightened. Declines in dealer market-making capacity as a result of structural or regulatory changes could decrease liquidity and/or increase volatility in the fixed income markets. Markets for fixed income securities may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Similarly, environmental and public health risks, such as natural disasters or epidemics, or widespread fear that such events may occur, may impact markets adversely and cause market volatility in both the short- and long-term. In response to these events, the Underlying SEI Fund's and, in turn, the Fund's value may fluctuate and/or the Underlying SEI Fund and the Fund may experience increased redemptions from shareholders, which may impact the Underlying SEI Fund's and the Fund's liquidity or force the Underlying SEI Fund and the Fund to sell securities into a declining or illiquid market. |
DEFENSIVE STRATEGY FUND - Class F Prospectus | SAAT DEFENSIVE STRATEGY FUND | Equity Market Risk [Member] | |

Risk [Text Block] | Equity Market Risk — The risk that the market value of a security may move up and down, sometimes rapidly and unpredictably. Market risk may affect a single issuer, an industry, a sector or the equity or bond market as a whole. Equity markets may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Similarly, environmental and public health risks, such as natural disasters or epidemics, or widespread fear that such events may occur, may impact markets adversely and cause market volatility in both the short- and long-term. |

Risk [Text Block] | Investment Company Risk — When the Fund or an Underlying SEI Fund invests in an investment company, in addition to directly bearing the expenses associated with its own operations, it will bear a pro rata portion of the investment company's expenses. In addition, while the risks of owning shares of an investment company generally reflect the risks of owning the underlying investments of the investment company, the Fund may be subject to additional or different risks than if the Fund or an Underlying SEI Fund had invested directly in the underlying investments. |
DEFENSIVE STRATEGY FUND - Class F Prospectus | SAAT DEFENSIVE STRATEGY FUND | Asset Allocation Risk [Member] | |

DEFENSIVE STRATEGY FUND - Class F Prospectus | SAAT DEFENSIVE STRATEGY FUND | U.S. Government Securities Risk [Member] | |
Prospectus [Line Items] | |
Risk [Text Block] | U.S. Government Securities Risk — Although U.S. Government securities are considered to be among the safest investments, they are still subject to the credit risk of the U.S. Government and are not guaranteed against price movements due to changing interest rates. Obligations issued by some U.S. Government agencies are backed by the U.S. Treasury, while others are backed solely by the ability of the agency to borrow from the U.S. Treasury or by the agency's own resources. No assurance can be given that the U.S. Government will provide financial support to its agencies and instrumentalities if it is not obligated by law to do so. |
DEFENSIVE STRATEGY FUND - Class F Prospectus | SAAT DEFENSIVE STRATEGY FUND | Interest Rate Risk [Member] | |
Prospectus [Line Items] | |
Risk [Text Block] | Interest Rate Risk — The risk that a change in interest rates will cause a fall in the value of fixed income securities, including U.S. Government securities, in which the Underlying SEI Funds invest. Generally, the value of the Underlying SEI Funds' fixed income securities will vary inversely with the direction of prevailing interest rates. Changing interest rates may have unpredictable effects on the markets and may affect the value and liquidity of instruments held by an Underlying SEI Fund. Although U.S. Government securities are considered to be among the safest investments, they are not guaranteed against price movements due to changing interest rates. |
DEFENSIVE STRATEGY FUND - Class F Prospectus | SAAT DEFENSIVE STRATEGY FUND | Commodity Investments Risk [Member] | |
Prospectus [Line Items] | |
Risk [Text Block] | Commodity Investments Risk — Certain Underlying SEI Funds may invest a portion of their assets in a wholly owned subsidiary that is not registered under the Investment Company Act of 1940, as amended, and invests directly in commodities and commodity-related instruments. Other Underlying SEI Funds may have indirect exposure to commodities by investing in commodity-related instruments. Commodity investments and derivatives may be more volatile and less liquid than direct investments in the underlying commodities themselves. Commodity-related equity returns can also be affected by the issuer's financial structure or the performance of unrelated businesses. The value of a commodity investment or a derivative investment in commodities is typically based upon the price movements of a physical commodity, a commodity futures contract or commodity index or some other readily measurable economic variable that is dependent upon changes in the value of commodities or the commodities markets. The value of these securities will rise or fall in response to changes in the underlying commodity or related benchmark or investment, changes in interest rates, or factors affecting a particular industry or commodity, such as natural disasters, weather and U.S. and international economic, political and regulatory developments. |
DEFENSIVE STRATEGY FUND - Class F Prospectus | SAAT DEFENSIVE STRATEGY FUND | Short Sales Risk [Member] | |
Prospectus [Line Items] | |
Risk [Text Block] | Short Sales Risk — A short sale involves the sale of a security that an Underlying SEI Fund does not own in the expectation of purchasing the same security (or a security exchangeable therefore) at a later date at a lower price. 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, that is potentially unlimited. 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. Investment in short sales may also cause an Underlying SEI Fund to incur expenses related to borrowing securities. In addition, shorting a future contract may require posting only a margin that may amount to less than the notional exposure of the contract. Such a practice may exacerbate the loss in a case of adverse price action. |
DEFENSIVE STRATEGY FUND - Class F Prospectus | SAAT DEFENSIVE STRATEGY FUND | Below Investment Grade Securities (Junk Bonds) Risk [Member] | |
Prospectus [Line Items] | |
Risk [Text Block] | Below Investment Grade Securities (Junk Bonds) Risk — Fixed income securities rated below investment grade (junk bonds) involve greater risk of default or downgrade and are generally more volatile than investment grade securities because the prospect for repayment of principal and interest of many of these securities is speculative. Because these securities typically offer a higher rate of return to compensate for these risks, they are sometimes referred to as "high yield bonds," but there is no guarantee that an investment in these securities will result in a high rate of return. |
DEFENSIVE STRATEGY FUND - Class F Prospectus | SAAT DEFENSIVE STRATEGY FUND | Small and Medium Capitalization Risk [Member] | |
Prospectus [Line Items] | |
Risk [Text Block] | Small and Medium Capitalization Risk — Small and medium capitalization companies 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. Small and medium capitalization stocks may be traded over-the-counter (OTC). OTC stocks may trade less frequently and in smaller volume than exchange listed stocks and may have more price volatility than that of exchange-listed stocks. |
DEFENSIVE STRATEGY FUND - Class F Prospectus | SAAT DEFENSIVE STRATEGY FUND | Large Capitalization Risk [Member] | |
Prospectus [Line Items] | |
Risk [Text Block] | Large Capitalization Risk — The risk that larger, more established companies may be unable to respond quickly to new competitive challenges such as changes in technology and consumer tastes. Larger companies also may not be able to attain the high growth rates of successful smaller companies. |
DEFENSIVE STRATEGY FUND - Class F Prospectus | SAAT DEFENSIVE STRATEGY FUND | Real Estate Industry Risk [Member] | |
Prospectus [Line Items] | |
Risk [Text Block] | Real Estate Industry Risk — Securities of companies principally engaged in the real estate industry may be subject to the risks associated with the direct ownership of real estate. Risks commonly associated with the direct ownership of real estate include fluctuations in the value of underlying properties, defaults by borrowers or tenants, changes in interest rates and risks related to general or local economic conditions. |
DEFENSIVE STRATEGY FUND - Class F Prospectus | SAAT DEFENSIVE STRATEGY FUND | Foreign Investment/Emerging Markets Risk [Member] | |
Prospectus [Line Items] | |
Risk [Text Block] | Foreign Investment/Emerging Markets Risk — The risk that non-U.S. securities may be subject to additional risks due to, among other things, political, social and economic developments abroad, currency movements, and different legal, regulatory, tax, accounting and audit environments. These additional risks may be heightened with respect to emerging market countries because political turmoil and rapid changes in economic conditions are more likely to occur in these countries. Investments in emerging markets are subject to the added risk that information in emerging market investments may be unreliable or outdated due to differences in regulatory, accounting or auditing and financial record keeping standards, or because less information about emerging market investments is publicly available. In addition, the rights and remedies associated with emerging market investments may be different than investments in developed markets. A lack of reliable information, rights and remedies increase the risks of investing in emerging markets in comparison to more developed markets. In addition, periodic U.S. Government restrictions on investments in issuers from certain foreign countries may require the Fund or an Underlying SEI Fund to sell such investments at inopportune times, which could result in losses to the Fund or an Underlying SEI Fund. |
DEFENSIVE STRATEGY FUND - Class F Prospectus | SAAT DEFENSIVE STRATEGY FUND | Currency Risk [Member] | |
Prospectus [Line Items] | |
Risk [Text Block] | Currency Risk — As a result of the Fund's and certain Underlying SEI Funds' investments in securities or other investments denominated in, and/or receiving revenues in, foreign currencies, the Fund will be subject to currency risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency hedged. In either event, the dollar value of an investment in the Fund or an Underlying SEI Fund would be adversely affected. Currency exchange rates may fluctuate in response to, among other things, changes in interest rates, intervention (or failure to intervene) by U.S. or foreign governments, central banks or supranational entities, or by the imposition of currency controls or other political developments in the United States or abroad. |
DEFENSIVE STRATEGY FUND - Class F Prospectus | SAAT DEFENSIVE STRATEGY FUND | Exchange-Traded Products Risk [Member] | |
Prospectus [Line Items] | |
Risk [Text Block] | Exchange-Traded Products Risk — The risks of owning interests of an ETP, such as an ETF 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. 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. |

Risk [Text Block] | Short Sales Risk — A short sale involves the sale of a security that an Underlying SEI Fund does not own in the expectation of purchasing the same security (or a security exchangeable therefore) at a later date at a lower price. 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, that is potentially unlimited. 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. Investment in short sales may also cause an Underlying SEI Fund to incur expenses related to borrowing securities. In addition, shorting a future contract may require posting only a margin that may amount to less than the notional exposure of the contract.

Risk [Text Block] | Short Sales Risk — A short sale involves the sale of a security that an Underlying SEI Fund does not own in the expectation of purchasing the same security (or a security exchangeable therefore) at a later date at a lower price. 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, that is potentially unlimited. 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. Investment in short sales may also cause an Underlying SEI Fund to incur expenses related to borrowing securities. In addition, shorting a future contract may require posting only a margin that may amount to less than the notional exposure of the contract. Such a practice may exacerbate the loss in a case of adverse price action. |

These additional risks may be heightened with respect to emerging market countries because political turmoil and rapid changes in economic conditions are more likely to occur in these countries. Investments in emerging markets are subject to the added risk that information in emerging market investments may be unreliable or outdated due to differences in regulatory, accounting or auditing and financial record keeping standards, or because less information about emerging market investments is publicly available. In addition, the rights and remedies associated with emerging market investments may be different than investments in developed markets. A lack of reliable information, rights and remedies increase the risks of investing in emerging markets in comparison to more developed markets. In addition, periodic U.S. Government restrictions on investments in issuers from certain foreign countries may require the Fund or an Underlying SEI Fund to sell such investments at inopportune times, which could result in losses to the Fund or an Underlying SEI Fund. |

Risk [Text Block] | Exchange-Traded Products (ETPs) Risk — The risks of owning interests of an ETP, such as an ETF 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. 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. |

Risk [Text Block] | Fixed Income Market Risk — 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. Generally, an Underlying SEI Fund's fixed income securities will decrease in value if interest rates rise and vice versa. In a low interest rate environment, risks associated with rising rates are heightened. Declines in dealer market-making capacity as a result of structural or regulatory changes could decrease liquidity and/or increase volatility in the fixed income markets. Markets for fixed income securities may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Similarly, environmental and public health risks, such as natural disasters or epidemics, or widespread fear that such events may occur, may impact markets adversely and cause market volatility in both the short- and long-term. In response to these events, the Underlying SEI Fund's and, in turn, the Fund's value may fluctuate and/or the Underlying SEI Fund and the Fund may experience increased redemptions from shareholders, which may impact the Underlying SEI Fund's and the Fund's liquidity or force the Underlying SEI Fund and the Fund to sell securities into a declining or illiquid market. |

Risk [Text Block] | Commodity Investments Risk — Certain Underlying SEI Funds may invest a portion of their assets in a wholly owned subsidiary that is not registered under the Investment Company Act of 1940, as amended, and invests directly in commodities and commodity-related instruments. Other Underlying SEI Funds may have indirect exposure to commodities by investing in commodity-related instruments. Commodity investments and derivatives may be more volatile and less liquid than direct investments in the underlying commodities themselves. Commodity-related equity returns can also be affected by the issuer's financial structure or the performance of unrelated businesses. The value of a commodity investment or a derivative investment in commodities is typically based upon the price movements of a physical commodity, a commodity futures contract or commodity index or some other readily measurable economic variable that is dependent upon changes in the value of commodities or the commodities markets. The value of these securities will rise or fall in response to changes in the underlying commodity or related benchmark or investment, changes in interest rates, or factors affecting a particular industry or commodity, such as natural disasters, weather and U.S. and international economic, political and regulatory developments. |

Risk [Text Block] | Fixed Income Market Risk — 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. Generally, an Underlying SEI Fund's fixed income securities will decrease in value if interest rates rise and vice versa. In a low interest rate environment, risks associated with rising rates are heightened. Declines in dealer market-making capacity as a result of structural or regulatory changes could decrease liquidity and/or increase volatility in the fixed income markets. Markets for fixed income securities may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Similarly, environmental and public health risks, such as natural disasters or epidemics, or widespread fear that such events may occur, may impact markets adversely and cause market volatility in both the short- and long-term. In response to these events, the Underlying SEI Fund's and, in turn, the Fund's value may fluctuate and/or the Underlying SEI Fund and the Fund may experience increased redemptions from shareholders, which may impact the Underlying SEI Fund's and the Fund's liquidity or force the Underlying SEI Fund and the Fund to sell securities into a declining or illiquid market. |

Risk [Text Block] | Foreign Investment/Emerging Markets Risk — The risk that non-U.S. securities may be subject to additional risks due to, among other things, political, social and economic developments abroad, currency movements, and different legal, regulatory, tax, accounting and audit environments. These additional risks may be heightened with respect to emerging market countries because political turmoil and rapid changes in economic conditions are more likely to occur in these countries. Investments in emerging markets are subject to the added risk that information in emerging market investments may be unreliable or outdated due to differences in regulatory, accounting or auditing and financial record keeping standards, or because less information about emerging market investments is publicly available. In addition, the rights and remedies associated with emerging market investments may be different than investments in developed markets. A lack of reliable information, rights and remedies increase the risks of investing in emerging markets in comparison to more developed markets. In addition, periodic U.S. Government restrictions on investments in issuers from certain foreign countries may require the Fund or an Underlying SEI Fund to sell such investments at inopportune times, which could result in losses to the Fund or an Underlying SEI Fund. |

Risk [Text Block] | Short Sales Risk — A short sale involves the sale of a security that an Underlying SEI Fund does not own in the expectation of purchasing the same security (or a security exchangeable therefore) at a later date at a lower price. 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, that is potentially unlimited. 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. Investment in short sales may also cause an Underlying SEI Fund to incur expenses related to borrowing securities. In addition, shorting a future contract may require posting only a margin that may amount to less than the notional exposure of the contract.

Risk [Text Block] | Foreign Investment/Emerging Markets Risk — The risk that non-U.S. securities may be subject to additional risks due to, among other things, political, social and economic developments abroad, currency movements, and different legal, regulatory, tax, accounting and audit environments. These additional risks may be heightened with respect to emerging market countries because political turmoil and rapid changes in economic conditions are more likely to occur in these countries. Investments in emerging markets are subject to the added risk that information in emerging market investments may be unreliable or outdated due to differences in regulatory, accounting or auditing and financial record keeping standards, or because less information about emerging market investments is publicly available. In addition, the rights and remedies associated with emerging market investments may be different than investments in developed markets. A lack of reliable information, rights and remedies increase the risks of investing in emerging markets in comparison to more developed markets. In addition, periodic U.S. Government restrictions on investments in issuers from certain foreign countries may require the Fund or an Underlying SEI Fund to sell such investments at inopportune times, which could result in losses to the Fund or an Underlying SEI Fund. |

Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency hedged. In either event, the dollar value of an investment in the Fund or an Underlying SEI Fund would be adversely affected. Currency exchange rates may fluctuate in response to, among other things, changes in interest rates, intervention (or failure to intervene) by U.S. or foreign governments, central banks or supranational entities, or by the imposition of currency controls or other political developments in the United States or abroad. |

Risk [Text Block] | Exchange-Traded Products Risk — The risks of owning interests of an ETP, such as an ETF 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. 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. |

Risk [Text Block] | Fixed Income Market Risk — 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. Generally, an Underlying SEI Fund's fixed income securities will decrease in value if interest rates rise and vice versa. In a low interest rate environment, risks associated with rising rates are heightened. Declines in dealer market-making capacity as a result of structural or regulatory changes could decrease liquidity and/or increase volatility in the fixed income markets. Markets for fixed income securities may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Similarly, environmental and public health risks, such as natural disasters or epidemics, or widespread fear that such events may occur, may impact markets adversely and cause market volatility in both the short- and long-term. In response to these events, the Underlying SEI Fund's and, in turn, the Fund's value may fluctuate and/or the Underlying SEI Fund and the Fund may experience increased redemptions from shareholders, which may impact the Underlying SEI Fund's and the Fund's liquidity or force the Underlying SEI Fund and the Fund to sell securities into a declining or illiquid market. |

Investments in emerging markets are subject to the added risk that information in emerging market investments may be unreliable or outdated due to differences in regulatory, accounting or auditing and financial record keeping standards, or because less information about emerging market investments is publicly available. In addition, the rights and remedies associated with emerging market investments may be different than investments in developed markets. A lack of reliable information, rights and remedies increase the risks of investing in emerging markets in comparison to more developed markets. In addition, periodic U.S. Government restrictions on investments in issuers from certain foreign countries may require the Fund or an Underlying SEI Fund to sell such investments at inopportune times, which could result in losses to the Fund or an Underlying SEI Fund. |

Risk [Text Block] | Currency Risk — As a result of the Fund's and certain Underlying SEI Funds' investments in securities or other investments denominated in, and/or receiving revenues in, foreign currencies, the Fund will be subject to currency risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency hedged. In either event, the dollar value of an investment in the Fund or an Underlying SEI Fund would be adversely affected.

Risk [Text Block] | Exchange-Traded Products Risk — The risks of owning interests of an ETP, such as an ETF 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. 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. |

In a low interest rate environment, risks associated with rising rates are heightened.

Other Underlying SEI Funds may have indirect exposure to commodities by investing in commodity-related instruments. Commodity investments and derivatives may be more volatile and less liquid than direct investments in the underlying commodities themselves. Commodity-related equity returns can also be affected by the issuer's financial structure or the performance of unrelated businesses. The value of a commodity investment or a derivative investment in commodities is typically based upon the price movements of a physical commodity, a commodity futures contract or commodity index or some other readily measurable economic variable that is dependent upon changes in the value of commodities or the commodities markets. The value of these securities will rise or fall in response to changes in the underlying commodity or related benchmark or investment, changes in interest rates, or factors affecting a particular industry or commodity, such as natural disasters, weather and U.S. and international economic, political and regulatory developments. |

Prospectus [Line Items] | |
Risk [Text Block] | Short Sales Risk — A short sale involves the sale of a security that an Underlying SEI Fund does not own in the expectation of purchasing the same security (or a security exchangeable therefore) at a later date at a lower price. 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, that is potentially unlimited. 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. Investment in short sales may also cause an Underlying SEI Fund to incur expenses related to borrowing securities. In addition, shorting a future contract may require posting only a margin that may amount to less than the notional exposure of the contract. Such a practice may exacerbate the loss in a case of adverse price action. |

Commodity investments and derivatives may be more volatile and less liquid than direct investments in the underlying commodities themselves. Commodity-related equity returns can also be affected by the issuer's financial structure or the performance of unrelated businesses. The value of a commodity investment or a derivative investment in commodities is typically based upon the price movements of a physical commodity, a commodity futures contract or commodity index or some other readily measurable economic variable that is dependent upon changes in the value of commodities or the commodities markets. The value of these securities will rise or fall in response to changes in the underlying commodity or related benchmark or investment, changes in interest rates, or factors affecting a particular industry or commodity, such as natural disasters, weather and U.S. and international economic, political and regulatory developments. |

Risk [Text Block] | Short Sales Risk — A short sale involves the sale of a security that an Underlying SEI Fund does not own in the expectation of purchasing the same security (or a security exchangeable therefore) at a later date at a lower price. 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, that is potentially unlimited. 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. Investment in short sales may also cause an Underlying SEI Fund to incur expenses related to borrowing securities. In addition, shorting a future contract may require posting only a margin that may amount to less than the notional exposure of the contract.

These additional risks may be heightened with respect to emerging market countries because political turmoil and rapid changes in economic conditions are more likely to occur in these countries. Investments in emerging markets are subject to the added risk that information in emerging market investments may be unreliable or outdated due to differences in regulatory, accounting or auditing and financial record keeping standards, or because less information about emerging market investments is publicly available. In addition, the rights and remedies associated with emerging market investments may be different than investments in developed markets. A lack of reliable information, rights and remedies increase the risks of investing in emerging markets in comparison to more developed markets.

In either event, the dollar value of an investment in the Fund or an Underlying SEI Fund would be adversely affected.

Risk [Text Block] | Exchange-Traded Products Risk — The risks of owning interests of an ETP, such as an ETF 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. 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. |

Risk [Text Block] | Fixed Income Market Risk — 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. Generally, an Underlying SEI Fund's fixed income securities will decrease in value if interest rates rise and vice versa. In a low interest rate environment, risks associated with rising rates are heightened. Declines in dealer market-making capacity as a result of structural or regulatory changes could decrease liquidity and/or increase volatility in the fixed income markets. Markets for fixed income securities may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Similarly, environmental and public health risks, such as natural disasters or epidemics, or widespread fear that such events may occur, may impact markets adversely and cause market volatility in both the short- and long-term. In response to these events, the Underlying SEI Fund's and, in turn, the Fund's value may fluctuate and/or the Underlying SEI Fund and the Fund may experience increased redemptions from shareholders, which may impact the Underlying SEI Fund's and the Fund's liquidity or force the Underlying SEI Fund and the Fund to sell securities into a declining or illiquid market. |

Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency hedged. In either event, the dollar value of an investment in the Fund or an Underlying SEI Fund would be adversely affected. Currency exchange rates may fluctuate in response to, among other things, changes in interest rates, intervention (or failure to intervene) by U.S. or foreign governments, central banks or supranational entities, or by the imposition of currency controls or other political developments in the United States or abroad. |

Risk [Text Block] | Exchange-Traded Products Risk — The risks of owning interests of an ETP, such as an ETF 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. 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. |

Risk [Text Block] | Fixed Income Market Risk — 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. Generally, an Underlying SEI Fund's fixed income securities will decrease in value if interest rates rise and vice versa. In a low interest rate environment, risks associated with rising rates are heightened. Declines in dealer market-making capacity as a result of structural or regulatory changes could decrease liquidity and/or increase volatility in the fixed income markets. Markets for fixed income securities may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Similarly, environmental and public health risks, such as natural disasters or epidemics, or widespread fear that such events may occur, may impact markets adversely and cause market volatility in both the short- and long-term. In response to these events, the Underlying SEI Fund's and, in turn, the Fund's value may fluctuate and/or the Underlying SEI Fund and the Fund may experience increased redemptions from shareholders, which may impact the Underlying SEI Fund's and the Fund's liquidity or force the Underlying SEI Fund and the Fund to sell securities into a declining or illiquid market. |

Other Underlying SEI Funds may have indirect exposure to commodities by investing in commodity-related instruments. Commodity investments and derivatives may be more volatile and less liquid than direct investments in the underlying commodities themselves. Commodity-related equity returns can also be affected by the issuer's financial structure or the performance of unrelated businesses. The value of a commodity investment or a derivative investment in commodities is typically based upon the price movements of a physical commodity, a commodity futures contract or commodity index or some other readily measurable economic variable that is dependent upon changes in the value of commodities or the commodities markets. The value of these securities will rise or fall in response to changes in the underlying commodity or related benchmark or investment, changes in interest rates, or factors affecting a particular industry or commodity, such as natural disasters, weather and U.S. and international economic, political and regulatory developments. |

Prospectus [Line Items] | |
Risk [Text Block] | Short Sales Risk — A short sale involves the sale of a security that an Underlying SEI Fund does not own in the expectation of purchasing the same security (or a security exchangeable therefore) at a later date at a lower price. 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, that is potentially unlimited. 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. Investment in short sales may also cause an Underlying SEI Fund to incur expenses related to borrowing securities. In addition, shorting a future contract may require posting only a margin that may amount to less than the notional exposure of the contract. Such a practice may exacerbate the loss in a case of adverse price action. |

Risk [Text Block] | Foreign Investment/Emerging Markets Risk — The risk that non-U.S. securities may be subject to additional risks due to, among other things, political, social and economic developments abroad, currency movements, and different legal, regulatory, tax, accounting and audit environments. These additional risks may be heightened with respect to emerging market countries because political turmoil and rapid changes in economic conditions are more likely to occur in these countries. Investments in emerging markets are subject to the added risk that information in emerging market investments may be unreliable or outdated due to differences in regulatory, accounting or auditing and financial record keeping standards, or because less information about emerging market investments is publicly available. In addition, the rights and remedies associated with emerging market investments may be different than investments in developed markets. A lack of reliable information, rights and remedies increase the risks of investing in emerging markets in comparison to more developed markets. In addition, periodic U.S. Government restrictions on investments in issuers from certain foreign countries may require the Fund or an Underlying SEI Fund to sell such investments at inopportune times, which could result in losses to the Fund or an Underlying SEI Fund. |

Risk [Text Block] | Commodity Investments Risk — Certain Underlying SEI Funds may invest a portion of their assets in a wholly owned subsidiary that is not registered under the Investment Company Act of 1940, as amended, and invests directly in commodities and commodity-related instruments. Other Underlying SEI Funds may have indirect exposure to commodities by investing in commodity-related instruments. Commodity investments and derivatives may be more volatile and less liquid than direct investments in the underlying commodities themselves. Commodity-related equity returns can also be affected by the issuer's financial structure or the performance of unrelated businesses. The value of a commodity investment or a derivative investment in commodities is typically based upon the price movements of a physical commodity, a commodity futures contract or commodity index or some other readily measurable economic variable that is dependent upon changes in the value of commodities or the commodities markets. The value of these securities will rise or fall in response to changes in the underlying commodity or related benchmark or investment, changes in interest rates, or factors affecting a particular industry or commodity, such as natural disasters, weather and U.S. and international economic, political and regulatory developments. |
MARKET GROWTH STRATEGY FUND - Class I Prospectus | SAAT MARKET GROWTH STRATEGY FUND | Short Sales Risk [Member] | |
Prospectus [Line Items] | |
Risk [Text Block] | Short Sales Risk — A short sale involves the sale of a security that an Underlying SEI Fund does not own in the expectation of purchasing the same security (or a security exchangeable therefore) at a later date at a lower price. 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, that is potentially unlimited. 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. Investment in short sales may also cause an Underlying SEI Fund to incur expenses related to borrowing securities. In addition, shorting a future contract may require posting only a margin that may amount to less than the notional exposure of the contract. Such a practice may exacerbate the loss in a case of adverse price action. |
MARKET GROWTH STRATEGY FUND - Class I Prospectus | SAAT MARKET GROWTH STRATEGY FUND | Below Investment Grade Securities (Junk Bonds) Risk [Member] | |
Prospectus [Line Items] | |
Risk [Text Block] | Below Investment Grade Securities (Junk Bonds) Risk — Fixed income securities rated below investment grade (junk bonds) involve greater risk of default or downgrade and are generally more volatile than investment grade securities because the prospect for repayment of principal and interest of many of these securities is speculative. Because these securities typically offer a higher rate of return to compensate for these risks, they are sometimes referred to as "high yield bonds," but there is no guarantee that an investment in these securities will result in a high rate of return. |
MARKET GROWTH STRATEGY FUND - Class I Prospectus | SAAT MARKET GROWTH STRATEGY FUND | Small and Medium Capitalization Risk [Member] | |
Prospectus [Line Items] | |
Risk [Text Block] | Small and Medium Capitalization Risk — Small and medium capitalization companies 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. Small and medium capitalization stocks may be traded over-the-counter (OTC). OTC stocks may trade less frequently and in smaller volume than exchange listed stocks and may have more price volatility than that of exchange-listed stocks. |

Risk [Text Block] | Large Capitalization Risk — The risk that larger, more established companies may be unable to respond quickly to new competitive challenges such as changes in technology and consumer tastes. Larger companies also may not be able to attain the high growth rates of successful smaller companies. |
MARKET GROWTH STRATEGY FUND - Class I Prospectus | SAAT MARKET GROWTH STRATEGY FUND | Real Estate Industry Risk [Member] | |
Prospectus [Line Items] | |
Risk [Text Block] | Real Estate Industry Risk — Securities of companies principally engaged in the real estate industry may be subject to the risks associated with the direct ownership of real estate. Risks commonly associated with the direct ownership of real estate include fluctuations in the value of underlying properties, defaults by borrowers or tenants, changes in interest rates and risks related to general or local economic conditions. |
MARKET GROWTH STRATEGY FUND - Class I Prospectus | SAAT MARKET GROWTH STRATEGY FUND | Foreign Investment/Emerging Markets Risk [Member] | |
Prospectus [Line Items] | |
Risk [Text Block] | Foreign Investment/Emerging Markets Risk — The risk that non-U.S. securities may be subject to additional risks due to, among other things, political, social and economic developments abroad, currency movements, and different legal, regulatory, tax, accounting and audit environments. These additional risks may be heightened with respect to emerging market countries because political turmoil and rapid changes in economic conditions are more likely to occur in these countries. Investments in emerging markets are subject to the added risk that information in emerging market investments may be unreliable or outdated due to differences in regulatory, accounting or auditing and financial record keeping standards, or because less information about emerging market investments is publicly available. In addition, the rights and remedies associated with emerging market investments may be different than investments in developed markets. A lack of reliable information, rights and remedies increase the risks of investing in emerging markets in comparison to more developed markets. In addition, periodic U.S. Government restrictions on investments in issuers from certain foreign countries may require the Fund or an Underlying SEI Fund to sell such investments at inopportune times, which could result in losses to the Fund or an Underlying SEI Fund. |
MARKET GROWTH STRATEGY FUND - Class I Prospectus | SAAT MARKET GROWTH STRATEGY FUND | Currency Risk [Member] | |
Prospectus [Line Items] | |
Risk [Text Block] | Currency Risk — As a result of the Fund's and certain Underlying SEI Funds' investments in securities or other investments denominated in, and/or receiving revenues in, foreign currencies, the Fund will be subject to currency risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency hedged. In either event, the dollar value of an investment in the Fund or an Underlying SEI Fund would be adversely affected. Currency exchange rates may fluctuate in response to, among other things, changes in interest rates, intervention (or failure to intervene) by U.S. or foreign governments, central banks or supranational entities, or by the imposition of currency controls or other political developments in the United States or abroad. |
MARKET GROWTH STRATEGY FUND - Class I Prospectus | SAAT MARKET GROWTH STRATEGY FUND | Exchange-Traded Products Risk [Member] | |
Prospectus [Line Items] | |
Risk [Text Block] | Exchange-Traded Products Risk — The risks of owning interests of an ETP, such as an ETF 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. 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. |
