Prospectus [Line Items]  
Risk [Text Block]

Non-Diversification Risk. The Fund is non-diversified, which means that it may invest in the securities of relatively few issuers. As a result, the Fund may be more susceptible to a single adverse economic or political occurrence affecting one or more of these issuers and may experience increased volatility due to its investments in those securities. However, the Fund intends to satisfy the asset diversification requirements under the Internal Revenue Code of 1986, as amended (the Code) for classification as a regulated investment company (RIC).

Risk [Text Block]

Growth Securities Risk. Growth stocks may be more volatile than other stocks because their prices are often based on expectations of future earnings growth rather than current results. Growth companies may trade at higher valuations and may be more sensitive to changes in earnings expectations, investor sentiment, and market conditions. If anticipated growth is not realized, the prices of growth securities may decline significantly. Growth stocks may underperform value stocks and other investments for extended periods.

Quality Securities Risk. There is no guarantee that the past performance of stocks determined to be quality stocks will continue to perform as such. 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.

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.

Tracking Error Risk. The risk that the Fund’s performance may vary substantially from the performance of the benchmark index it tracks as a result of cash flows, Fund expenses, imperfect correlation between the Fund’s investments and the benchmark and other factors.

SEI Ang Research Enhanced U.S. Large Cap Growth ETF | 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.

SEI Ang Research Enhanced U.S. Large Cap Growth ETF | Large Capitalization Risk [Member]  
Prospectus [Line Items]

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.

SEI Ang Research Enhanced U.S. Large Cap Growth ETF | Medium Capitalization Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Medium Capitalization Risk. The risk that 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, medium capitalization companies may have limited product lines, markets and financial resources and may depend upon a relatively small management group. Therefore, medium capitalization stocks may be more volatile than those of larger companies. 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.

Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risk. The Fund’s use of futures contracts is subject to leverage risk, correlation risk, liquidity risk and market risk. Market risk is described above, and leverage risk and liquidity risk are described below. Correlation risk is the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Each of these risks could cause the Fund to lose more than the principal amount invested in a derivative instrument. The Fund’s use of derivatives may also increase the amount of taxes payable by shareholders. Both U.S. and non-U.S. regulators have adopted and implemented regulations governing derivatives markets, the ultimate impact of which remains unclear.

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. 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.

SEI Ang Research Enhanced U.S. Large Cap Growth ETF | 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.

SEI Ang Research Enhanced U.S. Large Cap Growth ETF | Management Risk [Member]

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.

SEI Ang Research Enhanced U.S. Large Cap Growth ETF | Operational Risk [Member]

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.

SEI Ang Research Enhanced U.S. Large Cap Growth ETF | 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.

SEI Ang Research Enhanced U.S. Large Cap Growth ETF | 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 or face trading halts or delisting.

SEI Ang Research Enhanced U.S. Large Cap Growth ETF | 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.

SEI Ang Research Enhanced U.S. Large Cap Growth ETF | Index-Related Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Index-Related Risk. The Fund seeks investment results that correspond generally to the performance, before fees and expenses, of the Underlying Index as published by the Index Provider. There is no assurance that the Index Provider will compile the Underlying Index accurately, or that the Underlying Index will be determined, composed or calculated accurately. The Index Provider may cease publication of the Underlying Index or may terminate the license agreement allowing the Fund to use the Underlying Index, either of which could have a material adverse effect on the Fund. Market disruptions could cause delays in the Underlying Index’s reconstitution and rebalancing schedule. During any such delay, it is possible that the Underlying Index and, in turn, the Fund will deviate from the Underlying Index’s stated methodology and therefore experience returns different than those that would have been achieved under a normal reconstitution and rebalancing schedule. Generally, the Index Provider does not provide any warranty, or accept any liability, with respect to the quality, accuracy or completeness of the Underlying Index or its related data, and does not guarantee that the Underlying Index will be in line with its stated methodology. Errors in the Underlying Index’s data, computations and/or the construction of the Underlying Index in accordance with its stated methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders. The Adviser may have limited ability to detect such errors and neither the Adviser nor its affiliates provide any warranty or guarantee against such errors. Therefore, the gains, losses or costs associated with the Index Provider’s errors will generally be borne by the Fund and its shareholders.

SEI Ang Research Enhanced U.S. Large Cap Growth ETF | Index Licensing Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Index Licensing Risk. It is possible that the index license, to which an affiliate of SIMC is the licensee and under which the Adviser or the Fund is permitted to use the Underlying Index, will be terminated or may be disputed, impaired or cease to remain in effect. In such a case, the Adviser may be required to replace the Underlying Index with another index which it considers to be appropriate in light of the investment strategy of the Fund. The use of any such substitute index may have an adverse impact on the Fund’s performance. In

the event that the Adviser is unable to identify a suitable replacement for the Underlying Index, it may determine to terminate the Fund.

SEI Ang Research Enhanced U.S. Large Cap Growth ETF | Index Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Index Risk. Although the Adviser has licensed from the Index Provider the right to use the Underlying Index as part of implementing the Fund’s principal investment strategies, there can be no guarantee that the Underlying Index will be maintained indefinitely or that the Fund will be able to continue to utilize the Underlying Index to implement the Fund’s principal investment strategies indefinitely. If the Index Provider ceases to maintain the Underlying Index or terminates the license agreement allowing the Fund to use the Underlying Index such that the Fund no longer has the ability to utilize the Underlying Index to implement its principal investment strategies, or if other circumstances exist that the Adviser or the Fund’s Board of Trustees concludes substantially limit the Fund’s ability to gain investment exposure to the Underlying Index, the Adviser or the Fund’s Board of Trustees may substitute the Underlying Index with another index that it chooses in its sole discretion and upon 60 days’ prior written notice to shareholders. There can be no assurance that any substitute index so selected will be similar to the Underlying Index or will perform in a manner similar to the Underlying Index that it replaces. Unavailability of the Underlying Index could affect adversely the ability of the Fund to achieve its investment objective.

SEI Ang Research Enhanced U.S. Large Cap Growth ETF | Concentration Risk [Member]

Risk [Text Block]

Concentration Risk. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in the securities or other assets of one or more issuers, countries or other geographic units, markets, industries, project types, or asset classes.

SEI Ang Research Enhanced U.S. Large Cap Growth ETF | Exchange-Traded Funds Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Exchange-Traded Funds Risk. The risks of owning shares of an ETF generally reflect the risks of owning the underlying securities the ETF is designed to track, although lack of liquidity in an ETF could result in its value being more volatile than the underlying portfolio securities. When the Fund invests in an ETF, in addition to directly bearing the expenses associated with its own operations, it will bear a pro rata portion of the ETF’s expenses.

SEI Ang Research Enhanced U.S. Large Cap Growth ETF | 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.

Prospectus [Line Items]  
Risk [Text Block]

Preferred Stock Risk. Preferred stock represents an equity or ownership interest in an issuer that pays dividends at a specified rate and that has precedence over common stock in the payment of dividends. In the event an issuer is liquidated or declares bankruptcy, the claims of owners of bonds take precedence over the claims of those who own preferred and common stock.

SEI Ang Research Enhanced U.S. Large Cap Growth ETF | Warrants Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Warrants Risk. Warrants are instruments that entitle the holder to buy an equity security at a specific price for a specific period of time. Warrants may be more speculative than other types of investments. The

price of a warrant may be more volatile than the price of its underlying security, and a warrant may offer greater potential for capital appreciation as well as capital loss. A warrant ceases to have value if it is not exercised prior to its expiration date.

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.

Preferred Stock Risk. Preferred stock represents an equity or ownership interest in an issuer that pays dividends at a specified rate and that has precedence over common stock in the payment of dividends. In the event an issuer is liquidated or declares bankruptcy, the claims of owners of bonds take precedence over the claims of those who own preferred and common stock.

Warrants Risk. Warrants are instruments that entitle the holder to buy an equity security at a specific price for a specific period of time. Warrants may be more speculative than other types of investments. The price of a warrant may be more volatile than the price of its underlying security, and a warrant may offer greater potential for capital appreciation as well as capital loss. A warrant ceases to have value if it is not exercised prior to its expiration date.
