Investment Risks - SEI QIM U.S. Equity Factor Allocation Active ETF	Mar. 25, 2026
Risk Lose Money [Member]
Prospectus [Line Items]
Risk [Text Block]	As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments.
Risk Not Insured [Member]
Prospectus [Line Items]
Risk [Text Block]	An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, SIMC or any of its affiliates.
Equity Securities Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Equity Securities Risk. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes.
Quality Securities Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Quality Securities Risk. There is no guarantee that the past performance of stocks that SIMC determines are quality will continue. Companies that issue these stocks may experience lower than expected returns or may experience negative growth, as well as increased leverage, resulting in lower than expected or negative returns to Fund shareholders. Many factors can affect a stock's quality and performance, and the impact of these factors on a stock or its price can be difficult to predict.
Momentum Securities Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Momentum Securities Risk. Stocks that previously exhibited high momentum characteristics may not experience positive momentum or may experience more volatility than the market as a whole.
Value Securities Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	*Value Securities Risk*. Securities issued by companies that may be perceived as undervalued may fail to appreciate for long periods of time and may never realize their full potential value. SIMC may be unsuccessful in identifying undervalued securities. Value securities have generally performed better than non-value securities during periods of economic recovery (although there is no assurance that they will continue to do so). Value securities may go in and out of favor over time.
Volatility Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	*Volatility Risk*. Although SIMC seeks to construct a portfolio with lower volatility than the broad U.S. large cap equity market, there is no guarantee that SIMC will be successful. As a result, the Fund may not be any less volatile than the market as a whole, and could be more volatile.
Quantitative Investing Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Quantitative Investing Risk. Due to the significant role technology plays in quantitative strategies, they carry the risk of unintended or unrecognized issues or flaws in the design, coding, implementation or maintenance of the computer programs or technology used in the development and implementation of the quantitative strategy. Utility interruptions or other key systems outages also can impair the performance of quantitative investment strategies.
Market Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Market Risk. 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. The Fund's market price may deviate from the value of the Fund's underlying portfolio holdings, particularly in times of market stress, with the result that investors may pay significantly more or receive significantly less than the underlying value of the Fund shares bought or sold. This can be reflected as a spread between the bid and ask prices for the Fund quoted during the day or a premium or discount in the closing price from the Fund's NAV.
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.
Small and Medium Capitalization Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	*Small and Medium Capitalization Risk.* The risk that small and medium capitalization companies in which the Fund may invest 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 capitalization and medium capitalization stocks may be more volatile than those of larger companies. Small capitalization 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.
Investment Style Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	*Investment Style Risk.* The risk that the Fund's investment strategy may underperform other segments of the equity markets or the equity markets as a whole.
Depositary Receipts Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	*Depositary Receipts Risk.* Depositary receipts, such as ADRs, are certificates evidencing ownership of shares of a foreign issuer that are issued by depositary banks and generally trade on an established market. Depositary receipts are subject to many of the risks associated with investing directly in foreign securities, including, among other things, political, social and economic developments abroad, currency movements and different legal, regulatory, tax, accounting and audit environments.
Convertible and Preferred Securities Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	*Convertible and Preferred Securities Risk.* Convertible and preferred securities have many of the same characteristics as stocks, including many of the same risks. In addition, convertible securities may be more sensitive to changes in interest rates than stocks. Convertible securities may also have credit ratings below investment grade, meaning that they carry a higher risk of failure by the issuer to pay principal and/or interest when due.
Real Estate Investment Trusts (REITs) Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	*Real Estate Investment Trusts (REITs) Risk.* REITs are trusts that invest primarily in commercial real estate or real estate-related loans. The Fund's investments in REITs will 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. Some REITs may have limited diversification and may be subject to risks inherent in financing a limited number of properties.
Structured Securities Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	*Structured Securities Risk.* The payment and credit qualities of structured securities derive from their underlying assets, and they may behave in ways not anticipated by the Fund, or they may not receive tax, accounting or regulatory treatment anticipated by the Fund.
Risk of Investing in the U.S. [Member]
Prospectus [Line Items]
Risk [Text Block]	Risk of Investing in the U.S. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.
Issuer Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Changes in the financial condition or credit rating of an issuer of those securities may cause the value of the Fund to decline.
Market Trading Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	*Market Trading Risk*. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruptions in the creation/redemption process. Active trading markets for the Fund's shares may not be developed or maintained by market makers or Authorized Participants (as defined below). Authorized Participants are not obligated to make a market in the Fund's shares or to submit purchase or redemption orders for Creation Units (as defined below). In times of market stress, market makers or Authorized Participants may step away from their respective roles, which could lead to variances between the market price of the Fund's shares and its underlying NAV. Trading in shares on an exchange may be halted in certain circumstances. If a trading halt occurs, a shareholder may temporarily be unable to purchase or sell shares of the Fund. Any of these factors could lead the Fund's shares to trade at a premium or discount to NAV. Thus, you may pay more (or less) than NAV when you buy shares of the Fund in the secondary market, and you may receive less (or more) than NAV when you sell those shares in the secondary market, particularly during times of market stress. SIMC cannot predict whether shares will trade above (premium), below (discount) or at NAV or whether the spread between bid and ask prices will widen. In addition, there can be no assurance that the requirements of the listing exchange necessary to maintain the listing of the Fund will continue to be met.
Liquidity Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Liquidity Risk. In stressed market conditions, the market for the Fund's shares may become less liquid in response to deteriorating liquidity in the markets for the Fund's underlying portfolio holdings. This adverse effect on liquidity for the Fund's shares in turn could lead to differences between the market price of the Fund's shares and its underlying NAV and/or widening the spread between bid and ask prices.
Management Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	*Management Risk.* SIMC may not successfully implement the Fund's investment strategies and, as a result, the Fund may not meet its investment objective and/or underperform other investment vehicles with similar investment objectives and strategies.
Operational Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	*Operational Risk*. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund's service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures.
New Fund Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	New Fund Risk. The Fund is a new fund, with a limited operating history, which may result in additional risks for investors in the Fund. There can be no assurance that the Fund will grow to an economically viable size, in which case the Fund may cease operations. In such an event, investors may be required to liquidate or transfer their investments at an inopportune time.
Authorized Participant Concentration Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	*Authorized Participant Concentration Risk.* Only broker-dealers (referred to as Authorized Participants or APs) that have executed authorized participation agreements with respect to the Trust may engage in creation or redemption transactions directly with the Fund, and no AP is obligated to engage in creation and/or redemption transactions. To the extent that APs exit the business or are unable to proceed with orders, Fund shares may be more likely to trade at a premium or discount to NAV, have wider spreads between bid and ask prices, have wider spreads between bid and ask prices or face trading halts or delisting.
Cybersecurity Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	*Cybersecurity Risk.* Failures or breaches of the electronic systems of the Fund, SIMC, the Fund's distributor, and other service providers, market makers, APs or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund's business operations and/or potentially result in financial losses to the Fund and its shareholders.
