VictoryShares US 500 Volatility Wtd ETF

VictoryShares US 500 Volatility Wtd ETF

Investment Objective

The Fund seeks to provide investment results that track the performance of the Nasdaq Victory US Large Cap 500 Volatility Weighted Index before fees and expenses.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares ("Shares") of the Fund. Investors may incur usual or customary brokerage commissions and other charges on their purchases and sales of Shares of the Fund in the secondary market, which are not reflected in the table or the example below.

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees	VictoryShares US 500 Volatility Wtd ETF VictoryShares US 500 Volatility Wtd ETF USD ($)
Shareholder Fees (fees paid directly from your investment)	none

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	VictoryShares US 500 Volatility Wtd ETF VictoryShares US 500 Volatility Wtd ETF
Management Fees	0.30%
Other Expenses	0.11%
Total Annual Fund Operating Expenses	0.41%
Fee Waivers/Expense Reimbursements	(0.06%)	[1]
Total Annual Fund Operating Expenses After Fee Waivers and Expense Reimbursements	0.35%	[1]

Example:

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The amounts shown reflect the fee waiver/expense reimbursement in place through the expiration date. Although your actual costs may be higher or lower, based upon these assumptions your costs would be:

Expense Example	1 Year	3 Years	5 Years	10 Years
VictoryShares US 500 Volatility Wtd ETF | VictoryShares US 500 Volatility Wtd ETF | USD ($)	36	126	224	512

Portfolio Turnover:

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover will generally indicate higher transaction costs resulting in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover was 36% of the average value of its portfolio.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by investing, under normal market conditions, at least 80% of its assets directly or indirectly in the securities included in the Nasdaq Victory US Large Cap 500 Volatility Weighted Index (the "Index"), an unmanaged, volatility weighted index maintained exclusively by Nasdaq Inc. (the "Index Provider"). The Index Provider is not affiliated with the Fund or the Adviser.

The Index combines fundamental criteria with individual security risk control achieved through volatility weighting of individual securities. The Index follows a rules-based methodology to construct its constituent securities:

•  The Index universe begins with all publicly traded U.S. stocks and then screens for all companies with positive earnings in each of the four most recent quarters.

•  The Index identifies the 500 largest U.S. stocks by market capitalization measured at the time the Index's constituent securities are determined.

•  The 500 stocks are weighted based on their daily standard deviation (volatility) of daily price changes over the last 180 trading days. Stocks with lower volatility receive a higher weighting and stocks with higher volatility receive a lower weighting.

The Index is reconstituted every March and September (based on information as of the prior month-end) and is adjusted to limit exposure to any particular sector to 25%. The Index may include more than or fewer than 500 stocks depending on the number of companies meeting the Index's criteria. As of September 30, 2018, the Index had a market capitalization range from $2.3 billion to $1.1 trillion.

The Fund generally seeks to track the returns of the Index before fees and expenses by employing a replication strategy that seeks to hold all the stocks in the Index.

Principal Risks of Investing in the Fund

The Fund's investments are subject to the following principal risks:

nEquity Risk — The value of the equity securities in which the Fund invests may decline in response to developments affecting individual companies and/or general economic conditions. A company's earnings or dividends may not increase as expected. Price changes may be temporary or last for extended periods.

nETF Structure Risks — The Fund is structured as an exchange-traded fund ("ETF") and as a result is subject to special risks, including:

nNot Individually Redeemable — The Fund's Shares are not individually redeemable and may be redeemed by the Fund at its net asset value per share ("NAV") only in large blocks known as "Creation Units." You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit. Alternatively, you may redeem your Shares by selling them on the secondary market at prevailing market prices.

nTrading Issues — Trading in Shares on the Exchange (as defined below) may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. There is no guarantee that an active secondary market will develop for the Shares. In stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund's underlying portfolio holdings, which may lead to differences between the market price of the Shares and the underlying value of those Shares.

nMarket Price Variance Risk — The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a "bid-ask spread" charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a premium or discount to NAV.

nAuthorized Participants Concentration Risk — A limited number of financial institutions may be responsible for all or a significant portion of the creation and redemption activity for the Fund. If these firms exit the business or are unable or unwilling to process creation and/or redemption orders, Shares may trade at a premium or discount to NAV.

nIntraday Indicative Value (IIV) Risk — The Exchange intends to disseminate the approximate per share value of the Fund's published basket of securities ("Deposit Securities") every 15 seconds (the "intraday indicative value" or "IIV''). The IIV is not a "real-time" update of the NAV per share of the Fund because the IIV may not be calculated in the same manner as the NAV. For example, the calculation of the NAV may be subject to fair valuation at different prices than those used in the calculations of the IIV and, unlike the calculation of NAV, the IIV does not take into account Fund expenses. In addition, the IIV is based on the published Deposit Securities and not on the Fund's actual holdings.

nLarge Capitalization Stock Risk — The securities of large cap companies may underperform the securities of smaller cap companies or the market as a whole. The growth rate of larger, more established companies may lag those of smaller companies, especially during periods of economic expansion.

nPassive Investment Risk — The Fund is designed to track the Index and is not actively managed. The Fund will not buy or sell shares of an equity security due to current or projected performance of a security, industry or sector, unless that security is added to or removed, respectively, from the Index. The Fund does not, therefore, seek returns in excess of the Index, and does not attempt to take defensive positions or hedge against potential risks unless such defensive positions are also taken by the applicable Index.

nStock Market Risk — Overall stock market risks may affect the value of the Fund. Factors such as domestic and international economic growth and market conditions, interest rate levels and political events affect the securities markets.

nTracking Risk — The Fund's return may not match the return of the Index for a number of reasons, including: the Fund incurs operating expenses not applicable to the Index, and incurs costs in buying and selling securities; the Fund may not be fully invested at times; differences in the valuation of securities; and differences between the Fund's portfolio and the Index resulting from legal restrictions, cost, or liquidity constraints.

You may lose money by investing in the Fund. There is no guarantee that the Fund will achieve its objective. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Company (FDIC) or any other government agency.

By itself, the Fund does not constitute a complete investment plan and should be considered a long-term investment for investors who can afford to weather changes in the value of their investment.

Performance

The bar chart and table that follow are intended to help you understand some of the risks of investing in the Fund. The bar chart shows you how the Fund's calendar year performance has varied over the past 10 years (or the life of the Fund if shorter). The table compares the Fund's average annual total returns over the same period to a broad measure of market performance. We assume reinvestment of dividends and distributions.

Updated performance information is available on the Fund's website at VictorySharesLiterature.com.

After-tax returns use the historical highest individual federal marginal income tax rates and do not reflect the effect of state and local taxes. Actual after-tax returns depend on your tax situation and may differ from those shown. After-tax returns shown are not relevant if you own your Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

[1] Victory Capital Management Inc., the Fund's investment adviser, ("Adviser") has contractually agreed to waive its management fee and/or reimburse expenses through at least October 31, 2019 so that the total annual fund operating expenses after fee waiver and expense reimbursement (excluding certain items such as interest, taxes and brokerage commissions) do not exceed 0.35%. The Adviser is permitted to recoup advisory fees waived and expenses reimbursed by it or by the Fund's predecessor adviser for up to three years after the fiscal year in which the waiver or reimbursement took place, subject to the lesser of any operating expense limits in effect at the time of (a) the original waiver or expense reimbursement; or (b) the recoupment. This agreement may only be terminated by the Fund's Board of Trustees.

[1] Inception date is July 2, 2014.

VictoryShares Quality Growth ETF

VictoryShares Quality Growth ETF

Investment Objective

The Fund seeks to provide investment results that track the performance of the Nasdaq Victory Quality Growth Index before fees and expenses.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares ("Shares") of the Fund. Investors may incur usual or customary brokerage commissions and other charges on their purchases and sales of Shares of the Fund in the secondary market, which are not reflected in the table or the example below.

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees	VictoryShares Quality Growth ETF VictoryShares Quality Growth ETF USD ($)
Shareholder Fees (fees paid directly from your investment)	none

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	VictoryShares Quality Growth ETF VictoryShares Quality Growth ETF
Management Fees	0.30%
Other Expenses	0.41%	[1]
Total Annual Fund Operating Expenses	0.71%
Fee Waivers/Expense Reimbursements	(0.36%)	[2]
Total Annual Fund Operating Expenses After Fee Waivers and Expense Reimbursements	0.35%	[2]

Example:

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The amounts shown reflect the fee waiver/expense reimbursement in place through the expiration date. Although your actual costs may be higher or lower, based upon these assumptions your costs would be:

Expense Example	1 Year	3 Years
VictoryShares Quality Growth ETF | VictoryShares Quality Growth ETF | USD ($)	36	191

Portfolio Turnover:

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover will generally indicate higher transaction costs resulting in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the Example, affect the Fund's performance. Because the Fund has not yet commenced investment operations, no portfolio turnover information is available at this time.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by investing, under normal market conditions, at least 80% of its assets in securities included in the Nasdaq Victory Quality Growth Index (the "Index"). The Index utilizes a rules-based approach designed to generate investment returns with consistent quality and growth factor exposure. The Index is maintained exclusively by Nasdaq Inc. (the "Index Provider"). The Index Provider is not affiliated with the Fund or the Adviser.

The companies eligible for inclusion in the Index are derived from its starting universe, the mid- to large-capitalization U.S. companies included in the Nasdaq US Large Mid Cap Index ("Parent Index"), an index maintained by the Index Provider. The Parent Index consists of those companies with market capitalizations representing the top 90% of the U.S. investable universe.

The Index seeks to construct a diversified portfolio of companies that exhibit both quality and growth characteristics by ranking securities on the basis of a number of proprietary fundamental factors that have been identified by a quantitative multi-factor selection process developed by the Adviser. The Index selects those companies that rank highest in terms of exposure to both quality and growth factors and then weights the individual securities by applying a factor designed to favor companies with earnings stability. The Index is reconstituted every January, April, July and October (based on information as of the prior month-end).

The Fund generally seeks to track the returns of the Index before fees and expenses by employing a replication strategy that seeks to hold all the stocks in the Index in proportion to their weightings in the Index.

Principal Risks of Investing in the Fund

The Fund's investments are subject to the following principal risks:

nEquity Risk — The value of the equity securities in which the Fund invests may decline in response to developments affecting individual companies and/or general economic conditions. A company's earnings or dividends may not increase as expected. Price changes may be temporary or last for extended periods.

nETF Structure Risks — The Fund is structured as an exchange-traded fund ETF and as a result is subject to special risks, including:

nNot Individually Redeemable — The Fund's Shares are not individually redeemable and may be redeemed by the Fund at its net asset value per share ("NAV") only in large blocks known as "Creation Units." You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit. Alternatively, you may redeem your Shares by selling them on the secondary market at prevailing market prices.

nTrading Issues — Trading in Shares on the Exchange (as defined below) may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. There is no guarantee that an active secondary market will develop for the Shares. In stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund's underlying portfolio holdings, which may lead to differences between the market price of the Shares and the underlying value of those Shares.

nMarket Price Variance Risk — The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a "bid-ask spread" charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a premium or discount to NAV.

nAuthorized Participants Concentration Risk — A limited number of financial institutions may be responsible for all or a significant portion of the creation and redemption activity for the Fund. If these firms exit the business or are unable or unwilling to process creation and/or redemption orders, Shares may trade at a premium or discount to NAV.

nIntraday Indicative Value (IIV) Risk — The Exchange intends to disseminate the approximate per share value of the Fund's published basket of securities ("Deposit Securities") every 15 seconds (the "intraday indicative value" or "IIV''). The IIV is not a "real-time" update of the NAV per share of the Fund because the IIV may not be calculated in the same manner as the NAV. For example, the calculation of the NAV may be subject to fair valuation at different prices than those used in the calculations of the IIV and, unlike the calculation of NAV, the IIV does not take into account Fund expenses. In addition, the IIV is based on the published Deposit Securities and not on the Fund's actual holdings.

nInvestment Strategy Risk — Growth stocks may be more sensitive to changes in current or expected earnings than the values of other stocks, and they may fall out of favor if the companies' earnings growth does not meet expectations. Similarly, quality companies may fall out of favor based on changing market sentiment. In addition, the Index may not successfully identify companies that meet the Index's objective.

nLarge-Capitalization Stock Risk — The securities of large cap companies may underperform the securities of smaller cap companies or the market as a whole. The growth rate of larger, more established companies may lag those of smaller companies, especially during periods of economic expansion.

nLimited History of Operations — The Fund is a new ETF and, therefore, has a limited history of operations for investors to evaluate.

n  Mid-Capitalization Stock Risk — Mid-sized companies may be subject to a number of risks not associated with larger, more established companies, potentially making their stock prices more volatile and increasing the risk of loss.

nPassive Investment Risk — The Fund is designed to track the Index and is not actively managed. The Fund will not buy or sell shares of an equity security due to current or projected performance of a security, industry or sector, unless that security is added to or removed, respectively, from the Index. The Fund does not, therefore, seek returns in excess of the Index, and does not attempt to take defensive positions or hedge against potential risks unless such defensive positions are also taken by the applicable Index.

nStock Market Risk — Overall stock market risks may affect the value of the Fund. Factors such as domestic and international economic growth and market conditions, interest rate levels and political events affect the securities markets.

nTracking Risk — The Fund's return may not match the return of the Index for a number of reasons, including: the Fund incurs operating expenses not applicable to the Index, and incurs costs in buying and selling securities; the Fund may not be fully invested at times; differences in the valuation of securities; and differences between the Fund's portfolio and the Index resulting from legal restrictions, cost, or liquidity constraints.

You may lose money by investing in the Fund. There is no guarantee that the Fund will achieve its objective. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Company (FDIC) or any other government agency.

By itself, the Fund does not constitute a complete investment plan and should be considered a long-term investment for investors who can afford to weather changes in the value of their investment.

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its investment objective by investing, under normal market conditions, at least 80% of its net assets in securities included in the Nasdaq Victory Quality Value Index (the "Index"). The Index utilizes a rules-based approach designed to generate investment returns with consistent quality and value factor exposure. The Index is maintained exclusively by Nasdaq Inc. (the "Index Provider"). The Index Provider is not affiliated with the Fund or the Adviser.

The companies eligible for inclusion in the Index are derived from its starting universe, the mid- to large-capitalization U.S. companies included in the Nasdaq US Large Mid Cap Index ("Parent Index"), an index maintained by the Index Provider. The Parent Index consists of those companies with market capitalizations representing the top 90% of the U.S. investable universe.

The Index seeks to construct a diversified portfolio of companies that exhibit both quality and value characteristics by ranking securities on the basis of a number of proprietary fundamental factors that have been identified by a quantitative multi-factor selection process developed by the Adviser. The Index selects those companies that rank highest in terms of exposure to both quality and value factors and then weights the individual securities by applying a factor designed to favor companies with earnings stability. The Index is reconstituted every January, April, July and October (based on information as of the prior month-end).

The Fund generally seeks to track the returns of the Index before fees and expenses by employing a replication strategy that seeks to hold all the stocks in the Index in proportion to their weightings in the Index.

Principal Risks of Investing in the Fund

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund's investments are subject to the following principal risks:

nEquity Risk — The value of the equity securities in which the Fund invests may decline in response to developments affecting individual companies and/or general economic conditions. A company's earnings or dividends may not increase as expected. Price changes may be temporary or last for extended periods.

nETF Structure Risks — The Fund is structured as an exchange-traded fund ("ETF") and as a result is subject to special risks, including:

nNot Individually Redeemable — The Fund's Shares are not individually redeemable and may be redeemed by the Fund at its net asset value per share ("NAV") only in large blocks known as "Creation Units." You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit. Alternatively, you may redeem your Shares by selling them on the secondary market at prevailing market prices.

nTrading Issues — Trading in Shares on the Exchange (as defined below) may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. There is no guarantee that an active secondary market will develop for the Shares. In stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund's underlying portfolio holdings, which may lead to differences between the market price of the Shares and the underlying value of those Shares.

nMarket Price Variance Risk — The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a "bid-ask spread" charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a premium or discount to NAV.

nAuthorized Participants Concentration Risk — A limited number of financial institutions may be responsible for all or a significant portion of the creation and redemption activity for the Fund. If these firms exit the business or are unable or unwilling to process creation and/or redemption orders, Shares may trade at a premium or discount to NAV.

nIntraday Indicative Value (IIV) Risk — The Exchange intends to disseminate the approximate per share value of the Fund's published basket of securities ("Deposit Securities") every 15 seconds (the "intraday indicative value" or "IIV''). The IIV is not a "real-time" update of the NAV per share of the Fund because the IIV may not be calculated in the same manner as the NAV. For example, the calculation of the NAV may be subject to fair valuation at different prices than those used in the calculations of the IIV and, unlike the calculation of NAV, the IIV does not take into account Fund expenses. In addition, the IIV is based on the published Deposit Securities and not on the Fund's actual holdings.

nInvestment Strategy Risk — Value stocks may fall out of favor with investors and may underperform growth stocks in an up market. The intrinsic value of value stocks may never be fully recognized by the market or their price may decline. Similarly, quality companies may fall out of favor based on changing market sentiment. In addition, the Index may not successfully identify companies that meet the Index's objective.

nLarge-Capitalization Stock Risk — The securities of large cap companies may underperform the securities of smaller cap companies or the market as a whole. The growth rate of larger, more established companies may lag those of smaller companies, especially during periods of economic expansion.

nLimited History of Operations — The Fund is a new ETF and, therefore, has a limited history of operations for investors to evaluate.

nMid-Capitalization Stock Risk — Mid-sized companies may be subject to a number of risks not associated with larger, more established companies, potentially making their stock prices more volatile and increasing the risk of loss.

nPassive Investment Risk — The Fund is designed to track the Index and is not actively managed. The Fund will not buy or sell shares of an equity security due to current or projected performance of a security, industry or sector, unless that security is added to or removed, respectively, from the Index. The Fund does not, therefore, seek returns in excess of the Index, and does not attempt to take defensive positions or hedge against potential risks unless such defensive positions are also taken by the applicable Index.

nTracking Risk — The Fund's return may not match the return of the Index for a number of reasons, including: the Fund incurs operating expenses not applicable to the Index, and incurs costs in buying and selling securities; the Fund may not be fully invested at times; differences in the valuation of securities; and differences between the Fund's portfolio and the Index resulting from legal restrictions, cost, or liquidity constraints.

You may lose money by investing in the Fund. There is no guarantee that the Fund will achieve its objective. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Company (FDIC) or any other government agency.

By itself, the Fund does not constitute a complete investment plan and should be considered a long-term investment for investors who can afford to weather changes in the value of their investment.

The Fund seeks to provide investment results that track the performance of the Nasdaq Victory US Small Cap 500 Volatility Weighted Index before fees and expenses.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares ("Shares") of the Fund. Investors may incur usual or customary brokerage commissions and other charges on their purchases and sales of Shares of the Fund in the secondary market, which are not reflected in the table or the example below.

Example:

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The amounts shown reflect the fee waiver/expense reimbursement in place through the expiration date. Although your actual costs may be higher or lower, based upon these assumptions your costs would be:

Expense Example	1 Year	3 Years	5 Years	10 Years
VictoryShares US Small Cap Volatility Wtd ETF | VictoryShares US Small Cap Volatility Wtd ETF | USD ($)	36	139	251	580

Portfolio Turnover:

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover will generally indicate higher transaction costs resulting in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover was 47% of the average value of its portfolio.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by investing, under normal market conditions, at least 80% of its assets directly or indirectly in the securities included in the Nasdaq Victory US Small Cap 500 Volatility Weighted Index (the "Index"), an unmanaged, volatility weighted index maintained exclusively by Nasdaq Inc. (the "Index Provider"). The Index Provider is not affiliated with the Fund or the Adviser.

The Index combines fundamental criteria with individual security risk control achieved through volatility weighting of individual securities. The Index follows a rules-based methodology to construct its constituent securities:

•  The Index universe begins with all publicly traded U.S. stocks and then screens for all companies with positive earnings in each of the four most recent quarters.

•  The Index identifies the 500 largest U.S. companies with market capitalizations of less than $3 billion measured at the time the Index's constituent securities are determined.

•  The 500 stocks are weighted based on their daily standard deviation (volatility) of daily price changes over the last 180 trading days. Stocks with lower volatility receive a higher weighting and stocks with higher volatility receive a lower weighting.

The Index is reconstituted every March and September (based on information as of the prior month-end) and is adjusted to limit exposure to any particular sector to 25%. The Index may include more than or fewer than 500 stocks depending on the number of companies meeting the Index's criteria. As of September 30, 2018, the Index had a market capitalization range from $166.6 million to $3.3 billion.

The Fund generally seeks to track the returns of the Index before fees and expenses by employing a replication strategy that seeks to hold all the stocks in the Index.

Principal Risks of Investing in the Fund

The Fund's investments are subject to the following principal risks:

nEquity Risk — The value of the equity securities in which the Fund invests may decline in response to developments affecting individual companies and/or general economic conditions. A company's earnings or dividends may not increase as expected. Price changes may be temporary or last for extended periods.

nETF Structure Risks — The Fund is structured as an exchange-traded fund ("ETF") and as a result is subject to special risks, including:

In stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund's underlying portfolio holdings, which may lead to differences between the market price of the Shares and the underlying value of those Shares.

nMarket Price Variance Risk — The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a "bid-ask spread" charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a premium or discount to NAV.

In addition, the IIV is based on the published Deposit Securities and not on the Fund's actual holdings.

nLimited History of Operations — The Fund is a new ETF and, therefore, has a limited history of operations for investors to evaluate.

nLiquidity Risk — Lack of a ready market or restrictions on resale may limit the ability of the Fund to dispose of certain holdings quickly or at prices that represent true market value in the judgment of the Adviser. In addition, the Fund, by itself or together with other accounts managed by the Adviser, may hold a position in a security that is large relative to the typical trading volume for that security, which can make it difficult for the Fund to dispose of the position at an advantageous time or price. Illiquid securities and relatively less liquid securities may also be difficult to value.

nPassive Investment Risk — The Fund is designed to track the Index and is not actively managed. The Fund will not buy or sell shares of an equity security due to current or projected performance of a security, industry or sector, unless that security is added to or removed, respectively, from the Index. The Fund does not, therefore, seek returns in excess of the Index, and does not attempt to take defensive positions or hedge against potential risks unless such defensive positions are also taken by the applicable Index.

nSmall Company Risk — Small-sized companies may be subject to a number of risks not associated with larger, more established companies, potentially making their stock prices more volatile and increasing the risk of loss. Smaller companies may have limited markets, product lines, or financial resources and lack management experience and may experience higher failure rates than larger companies.

nStock Market Risk — Overall stock market risks may affect the value of the Fund. Factors such as domestic and international economic growth and market conditions, interest rate levels and political events affect the securities markets.

nTracking Risks — The Fund's return may not match the return of the Index for a number of reasons, including: the Fund incurs operating expenses not applicable to the Index, and incurs costs in buying and selling securities; the Fund may not be fully invested at times; differences in the valuation of securities; and differences between the Fund's portfolio and the Index resulting from legal restrictions, cost, or liquidity constraints.

The Fund does not, therefore, seek returns in excess of the Index, and does not attempt to take defensive positions or hedge against potential risks unless such defensive positions are also taken by the applicable Index.

nSmall Company Risk — Small-sized companies may be subject to a number of risks not associated with larger, more established companies, potentially making their stock prices more volatile and increasing the risk of loss. Smaller companies may have limited markets, product lines, or financial resources and lack management experience and may experience higher failure rates than larger companies.

nStock Market Risk — Overall stock market risks may affect the value of the Fund. Factors such as domestic and international economic growth and market conditions, interest rate levels and political events affect the securities markets.

nTracking Risks — The Fund's return may not match the return of the Index for a number of reasons, including: the Fund incurs operating expenses not applicable to the Index, and incurs costs in buying and selling securities; the Fund may not be fully invested at times; differences in the valuation of securities; and differences between the Fund's portfolio and the Index resulting from legal restrictions, cost, or liquidity constraints.

You may lose money by investing in the Fund. There is no guarantee that the Fund will achieve its objective. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Company (FDIC) or any other government agency.

By itself, the Fund does not constitute a complete investment plan and should be considered a long-term investment for investors who can afford to weather changes in the value of their investment.

VictoryShares International Volatility Wtd ETF

VictoryShares International Volatility Wtd ETF

Investment Objective

The Fund seeks to provide investment results that track the performance of the Nasdaq Victory International 500 Volatility Weighted Index before fees and expenses.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares ("Shares") of the Fund. Investors may incur usual or customary brokerage commissions and other charges on their purchases and sales of Shares of the Fund in the secondary market, which are not reflected in the table or the example below.

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees	VictoryShares International Volatility Wtd ETF VictoryShares International Volatility Wtd ETF USD ($)
Shareholder Fees (fees paid directly from your investment)	none

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	VictoryShares International Volatility Wtd ETF VictoryShares International Volatility Wtd ETF
Management Fees	0.40%
Other Expenses	0.58%
Total Annual Fund Operating Expenses	0.98%
Fee Waivers/Expense Reimbursements	(0.53%)	[1]
Total Annual Fund Operating Expenses After Fee Waivers and Expense Reimbursements	0.45%	[1]

Example:

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The amounts shown reflect the fee waiver/expense reimbursement in place through the expiration date. Although your actual costs may be higher or lower, based upon these assumptions your costs would be:

Expense Example	1 Year	3 Years	5 Years	10 Years
VictoryShares International Volatility Wtd ETF | VictoryShares International Volatility Wtd ETF | USD ($)	46	259	490	1,153

Portfolio Turnover:

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover will generally indicate higher transaction costs resulting in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover was 37% of the average value of its portfolio.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by investing, under normal market conditions, at least 80% of its assets directly or indirectly in the securities included in the Nasdaq Victory International 500 Volatility Weighted Index (the "Index"), an unmanaged, volatility weighted index maintained exclusively by Nasdaq Inc. (the "Index Provider"). The Index Provider is not affiliated with the Fund or the Adviser.

The Index combines fundamental criteria with individual security risk control achieved through volatility weighting of individual securities. The Index follows a rules-based methodology to construct its constituent securities:

•  The Index universe begins with all publicly traded foreign companies and then screens for all companies with positive earnings in each of the four most recent quarters.

•  The Index identifies the 500 largest foreign companies by market capitalization measured at the time the Index's constituent securities are determined.

•  The 500 stocks are weighted based on their daily standard deviation (volatility) of daily price changes over the last 180 trading days. Stocks with lower volatility receive a higher weighting and stocks with higher volatility receive a lower weighting.

The Index considers foreign companies to be those that are organized or domiciled in a developed country (excluding the U.S. and emerging markets) and whose stock principally trades on a foreign exchange. Representative developed markets include Canada, France, Germany, Japan, Hong Kong and Australia.

The Index is reconstituted every March and September (based on information as of the prior month-end) and is adjusted to limit exposure to any particular country to 20% and any particular sector to 25%. The Index may include more than or fewer than 500 stocks depending on the number of companies meeting the Index's criteria.

The Fund seeks to track the returns of the Index before fees and expenses by employing, under normal circumstances, a "sampling" process to invest in a representative sample of stocks included in the Index. The Fund's portfolio managers select these stocks using a statistical optimization process designed to produce investment characteristics that closely approximate those of the Index.

Principal Risks of Investing in the Fund

The Fund's investments are subject to the following principal risks:

nEquity Risk — The value of the equity securities in which the Fund invests may decline in response to developments affecting individual companies and/or general economic conditions. A company's earnings or dividends may not increase as expected. Price changes may be temporary or last for extended periods.

nETF Structure Risks — The Fund is structured as an exchange-traded fund ("ETF") and as a result is subject to special risks, including:

nNot Individually Redeemable — The Fund's shares ("Shares") are not individually redeemable and may be redeemed by the Fund at its net asset value per share ("NAV") only in large blocks known as "Creation Units." You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit. Alternatively, you may redeem your Shares by selling them on the secondary market at prevailing market prices.

nTrading Issues — Trading in Shares on the Exchange (as defined below) may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. There is no guarantee that an active secondary market will develop for the Shares. In stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund's underlying portfolio holdings, which may lead to differences between the market price of the Shares and the underlying value of those Shares.

nMarket Price Variance Risk — The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a "bid-ask spread" charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a premium or discount to NAV.

nInternational Closed Market Trading Risk — Many of the Fund's underlying securities trade on foreign exchanges that are closed when the Exchange (as defined below) is open; consequently, events may transpire while such foreign exchanges are closed but the Exchange is open that may change the value of such underlying securities relative to their last quoted prices on such foreign exchanges.

nIntraday Indicative Value (IIV) Risk — The Exchange intends to disseminate the approximate per share value of the Fund's published basket of securities ("Deposit Securities") every 15 seconds (the "intraday indicative value" or "IIV''). The IIV is not a "real-time" update of the NAV per share of the Fund because the IIV may not be calculated in the same manner as the NAV. For example, the calculation of the NAV may be subject to fair valuation at different prices than those used in the calculations of the IIV and, unlike the calculation of NAV, the IIV does not take into account Fund expenses. The IIV calculations are based on local market prices and may not reflect events that occur subsequent to the local market's close which could affect premiums and discounts between the IIV and the market price of the Shares. In addition, the IIV is based on the published Deposit Securities and not on the Fund's actual holdings.

nAuthorized Participants Concentration Risk — A limited number of financial institutions may be responsible for all or a significant portion of the creation and redemption activity for the Fund. If these firms exit the business or are unable or unwilling to process creation and/or redemption orders, Shares may trade at a premium or discount to NAV.

nForeign Investment Risks:

nForeign Exposure Risk — Special risks associated with investments in foreign markets may include less liquidity, greater volatility, less developed or less efficient trading markets, lack of comprehensive company information, political instability and differing auditing and legal standards.

nCurrency Risk — The Fund's net asset value could decline as a result of changes in the exchange rates between foreign currencies and the US dollar. Additionally, certain foreign countries may impose restrictions on the ability of issuers of foreign securities to make payment of principal and interest to investors located outside the country, due to blockage of foreign currency exchanges or otherwise.

nLimited History of Operations — The Fund is a new ETF and, therefore, has a limited history of operations for investors to evaluate.

nPassive Investment Risk — The Fund is designed to track the Index and is not actively managed. The Fund will not buy or sell shares of an equity security due to current or projected performance of a security, industry or sector, unless that security is added to or removed, respectively, from the Index. The Fund does not, therefore, seek returns in excess of the Index, and does not attempt to take defensive positions or hedge against potential risks unless such defensive positions are also taken by the applicable Index.

nSampling Risk — The Fund's use of a representative sampling approach, if used, could result in its holding a smaller number of securities than are in the Index. As a result, an adverse development with an issuer or a small number of issuers of securities held by the Fund could result in a greater decline in NAV than would be the case if the Fund held all of the securities in the Index. To the extent the assets in the Fund are smaller, these risks will be greater.

nStock Market Risk — Overall stock market risks may affect the value of the Fund. Factors such as domestic and international economic growth and market conditions, interest rate levels and political events affect the securities markets.

nTracking Risk — The Fund's return may not match the return of the Index for a number of reasons, including: the Fund incurs operating expenses not applicable to the Index, and incurs costs in buying and selling securities; the Fund may not be fully invested at times; differences in the valuation of securities; and differences between the Fund's portfolio and the Index resulting from legal restrictions, cost, or liquidity constraints. The Fund's use of representative sampling may cause the tracking error to be higher than would be the case if the Fund purchased all of the securities in the Index.

You may lose money by investing in the Fund. There is no guarantee that the Fund will achieve its objective. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Company (FDIC) or any other government agency.

By itself, the Fund does not constitute a complete investment plan and should be considered a long-term investment for investors who can afford to weather changes in the value of their investment.

You may lose money by investing in the Fund. There is no guarantee that the Fund will achieve its objective. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Company (FDIC) or any other government agency.

By itself, the Fund does not constitute a complete investment plan and should be considered a long-term investment for investors who can afford to weather changes in the value of their investment.

VictoryShares Emerging Market Volatility Wtd ETF

VictoryShares Emerging Market Volatility Wtd ETF

Investment Objective

The Fund seeks to provide investment results that track the performance of the Nasdaq Victory Emerging Market 500 Volatility Weighted Index before fees and expenses.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares ("Shares") of the Fund. Investors may incur usual or customary brokerage commissions and other charges on their purchases and sales of Shares of the Fund in the secondary market, which are not reflected in the table or the example below.

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees	VictoryShares Emerging Market Volatility Wtd ETF VictoryShares Emerging Market Volatility Wtd ETF USD ($)
Shareholder Fees (fees paid directly from your investment)	none

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	VictoryShares Emerging Market Volatility Wtd ETF VictoryShares Emerging Market Volatility Wtd ETF
Management Fees	0.45%
Other Expenses	0.78%
Total Annual Fund Operating Expenses	1.23%
Fee Waivers/Expense Reimbursements	(0.73%)	[1]
Total Annual Fund Operating Expenses After Fee Waivers and Expense Reimbursements	0.50%	[1]

Example:

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The amounts shown reflect the fee waiver/expense reimbursement in place through the expiration date. Although your actual costs may be higher or lower, based upon these assumptions your costs would be:

Expense Example	1 Year	3 Years	5 Years	10 Years
VictoryShares Emerging Market Volatility Wtd ETF | VictoryShares Emerging Market Volatility Wtd ETF | USD ($)	51	318	605	1,424

Portfolio Turnover:

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover will generally indicate higher transaction costs resulting in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover was 53% of the average value of its portfolio.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by investing, under normal market conditions, at least 80% of its assets directly or indirectly in the securities included in the Nasdaq Victory Emerging Market 500 Volatility Weighted Index (the "Index"), an unmanaged, volatility weighted index maintained exclusively by Nasdaq Inc. (the "Index Provider"). The Index Provider is not affiliated with the Fund or the Adviser.

The Index combines fundamental criteria with individual security risk control achieved through volatility weighting of individual securities. The Index follows a rules-based methodology to construct its constituent securities:

•  The Index universe begins with all publicly traded companies in emerging market countries and then screens for all companies with positive earnings in each of the four most recent quarters.

•  The Index identifies up to the 500 largest emerging market companies by market capitalization measured at the time the Index's constituent securities are determined.

•  The 500 stocks are weighted based on their daily standard deviation (volatility) of daily price changes over the last 180 trading days. Stocks with lower volatility receive a higher weighting and stocks with higher volatility receive a lower weighting.

The Index considers emerging market companies to be those that are organized or domiciled in an emerging market country and whose stock principally trades on a foreign exchange. Emerging markets are generally those with a less-developed economy and per capita income significantly lower than the U.S. or other developed countries. Representative emerging market countries include China (Asia), Brazil (South America), Russia (Europe and Asia), India (Asia) and Egypt (Africa).

The Index is reconstituted every March and September (based on information as of the prior month-end) and is adjusted to limit exposure to any particular country to 20% and any particular sector to 25%. The Index may include more than or less than 500 stocks depending on the number of companies meeting the Index's criteria.

The Fund seeks to track the returns of the Index before fees and expenses by employing, under normal circumstances, a "sampling" process to invest in a representative sample of stocks included in the Index. The Fund's portfolio managers select these stocks using a statistical optimization process designed to produce investment characteristics that closely approximate those of the Index.

At times, the Fund may invest in other investment companies, including exchange-traded funds ("ETFs"), in order to access a particular asset class or market.

Principal Risks of Investing in the Fund

The Fund's investments are subject to the following principal risks:

nEquity Risk — The value of the equity securities in which the Fund invests may decline in response to developments affecting individual companies and/or general economic conditions. A company's earnings or dividends may not increase as expected. Price changes may be temporary or last for extended periods.

nETF Structure Risks — The Fund is structured as an ETF and as a result is subject to special risks, including:

nNot Individually Redeemable — The Fund's Shares ("Shares") are not individually redeemable and may be redeemed by the Fund at its net asset value per share ("NAV") only in large blocks known as "Creation Units." You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit. Alternatively, you may redeem your Shares by selling them on the secondary market at prevailing market prices.

nTrading Issues — Trading in Shares on the Exchange (as defined below) may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. There is no guarantee that an active secondary market will develop for the Shares. In stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund's underlying portfolio holdings, which may lead to differences between the market price of the Shares and the underlying value of those Shares.

nMarket Price Variance Risk — The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a "bid-ask spread" charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a premium or discount to NAV.

nInternational Closed Market Trading Risk — Many of the Fund's underlying securities trade on foreign exchanges that are closed when the Exchange (as defined below) is open; consequently, events may transpire while such foreign exchanges are closed but the Exchange is open that may change the value of such underlying securities relative to their last quoted prices on such foreign exchanges. Because the Fund generally relies on the last quoted prices for such securities when calculating its NAV, such events may cause Shares to trade at a premium or discount to NAV.

nAuthorized Participants Concentration Risk — A limited number of financial institutions may be responsible for all or a significant portion of the creation and redemption activity for the Fund. If these firms exit the business or are unable or unwilling to process creation and/or redemption orders, Shares may trade at a premium or discount to NAV.

nIntraday Indicative Value (IIV) Risk — The Exchange intends to disseminate the approximate per share value of the Fund's published basket of securities ("Deposit Securities") every 15 seconds (the "intraday indicative value" or "IIV''). The IIV is not a "real-time" update of the NAV per share of the Fund because the IIV may not be calculated in the same manner as the NAV. For example, the calculation of the NAV may be subject to fair valuation at different prices than those used in the calculations of the IIV and, unlike the calculation of NAV, the IIV does not take into account Fund expenses. In addition, the IIV is based on the published Deposit Securities and not on the Fund's actual holdings.

nForeign Investment Risks:

nForeign Exposure Risk — Special risks associated with investments in foreign markets may include less liquidity, greater volatility, less developed or less efficient trading markets, lack of comprehensive company information, political instability and differing auditing and legal standards.

nEmerging Markets Risk — All of the risks associated with investing in foreign securities are increased in connection with investments in emerging markets securities. Emerging market countries may have relatively unstable governments, weaker economies, and less-developed legal systems which do not protect securities holders. Emerging market economies may be based on only a few industries and security issuers may be more susceptible to economic weakness and more likely to default. Emerging market securities also tend to be less liquid.

nCurrency Risk — The Fund's net asset value could decline as a result of changes in the exchange rates between foreign currencies and the US dollar. Additionally, certain foreign countries may impose restrictions on the ability of issuers of foreign securities to make payment of principal and interest to investors located outside the country, due to blockage of foreign currency exchanges or otherwise.

nInvestment Company Risk — An investment company or similar vehicle (including an ETF) in which the Fund invests may not achieve its investment objective. Underlying investment vehicles are subject to investment advisory and other expenses, which will be indirectly paid by the Fund. Lack of liquidity in an ETF could result in an ETF being more volatile than the underlying portfolio of securities.

nLimited History of Operations — The Fund is a new ETF and, therefore, has a limited history of operations for investors to evaluate.

nLiquidity Risk — In certain circumstances, such as the disruption of the orderly markets for the securities in which the Fund invests, the Fund might not be able to dispose of certain holdings quickly or at prices that represent true market value in the judgment of the Adviser. Markets for the securities in which the Fund invests may be disrupted by a number of events, including but not limited to economic crises, natural disasters, new legislation, or regulatory changes, and may prevent the Fund from limiting losses, realizing gains or achieving a high correlation with the Index.

nPassive Investment Risk — The Fund is designed to track the Index and is not actively managed. The Fund will not buy or sell shares of an equity security due to current or projected performance of a security, industry or sector, unless that security is added to or removed, respectively, from the Index. The Fund does not, therefore, seek returns in excess of the Index, and does not attempt to take defensive positions or hedge against potential risks unless such defensive positions are also taken by the applicable Index.

nSampling Risk — The Fund's use of a representative sampling approach, if used, could result in its holding a smaller number of securities than are in the Index. As a result, an adverse development with an issuer or a small number of issuers of securities held by the Fund could result in a greater decline in NAV than would be the case if the Fund held all of the securities in the Index. To the extent the assets in the Fund are smaller, these risks will be greater.

nSmaller Company Risk — Small and mid-sized companies may be subject to a number of risks not associated with larger, more established companies, potentially making their stock prices more volatile and increasing the risk of loss. Smaller companies may have limited markets, product lines, or financial resources and lack management experience and may experience higher failure rates than larger companies.

nStock Market Risk — Overall stock market risks may affect the value of the Fund. Factors such as domestic and international economic growth and market conditions, interest rate levels and political events affect the securities markets.

nTracking Risks — The Fund's return may not match the return of the Index for a number of reasons, including: the Fund incurs operating expenses not applicable to the Index, and incurs costs in buying and selling securities; the Fund may not be fully invested at times; differences in the valuation of securities; and differences between the Fund's portfolio and the Index resulting from legal restrictions, cost, or liquidity constraints. The Fund's use of representative sampling may cause the tracking error to be higher than would be the case if the Fund purchased all of the securities in the Index.

You may lose money by investing in the Fund. There is no guarantee that the Fund will achieve its objective. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Company (FDIC) or any other government agency.

By itself, the Fund does not constitute a complete investment plan and should be considered a long-term investment for investors who can afford to weather changes in the value of their investment.

nInvestment Company Risk — An investment company or similar vehicle (including an ETF) in which the Fund invests may not achieve its investment objective. Underlying investment vehicles are subject to investment advisory and other expenses, which will be indirectly paid by the Fund. Lack of liquidity in an ETF could result in an ETF being more volatile than the underlying portfolio of securities.

nLimited History of Operations — The Fund is a new ETF and, therefore, has a limited history of operations for investors to evaluate.

nLiquidity Risk — In certain circumstances, such as the disruption of the orderly markets for the securities in which the Fund invests, the Fund might not be able to dispose of certain holdings quickly or at prices that represent true market value in the judgment of the Adviser. Markets for the securities in which the Fund invests may be disrupted by a number of events, including but not limited to economic crises, natural disasters, new legislation, or regulatory changes, and may prevent the Fund from limiting losses, realizing gains or achieving a high correlation with the Index.

nPassive Investment Risk — The Fund is designed to track the Index and is not actively managed. The Fund will not buy or sell shares of an equity security due to current or projected performance of a security, industry or sector, unless that security is added to or removed, respectively, from the Index. The Fund does not, therefore, seek returns in excess of the Index, and does not attempt to take defensive positions or hedge against potential risks unless such defensive positions are also taken by the applicable Index.

nSampling Risk — The Fund's use of a representative sampling approach, if used, could result in its holding a smaller number of securities than are in the Index. As a result, an adverse development with an issuer or a small number of issuers of securities held by the Fund could result in a greater decline in NAV than would be the case if the Fund held all of the securities in the Index. To the extent the assets in the Fund are smaller, these risks will be greater.

nSmaller Company Risk — Small and mid-sized companies may be subject to a number of risks not associated with larger, more established companies, potentially making their stock prices more volatile and increasing the risk of loss. Smaller companies may have limited markets, product lines, or financial resources and lack management experience and may experience higher failure rates than larger companies.

nStock Market Risk — Overall stock market risks may affect the value of the Fund. Factors such as domestic and international economic growth and market conditions, interest rate levels and political events affect the securities markets.

nTracking Risks — The Fund's return may not match the return of the Index for a number of reasons, including: the Fund incurs operating expenses not applicable to the Index, and incurs costs in buying and selling securities; the Fund may not be fully invested at times; differences in the valuation of securities; and differences between the Fund's portfolio and the Index resulting from legal restrictions, cost, or liquidity constraints. The Fund's use of representative sampling may cause the tracking error to be higher than would be the case if the Fund purchased all of the securities in the Index.

You may lose money by investing in the Fund. There is no guarantee that the Fund will achieve its objective. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Company (FDIC) or any other government agency.

By itself, the Fund does not constitute a complete investment plan and should be considered a long-term investment for investors who can afford to weather changes in the value of their investment.

VictoryShares US Large Cap High Div Volatility Wtd ETF

VictoryShares US Large Cap High Div Volatility Wtd ETF

Investment Objective

The Fund seeks to provide investment results that track the performance of the Nasdaq Victory US Large Cap High Dividend 100 Volatility Weighted Index before fees and expenses.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares ("Shares") of the Fund. Investors may incur usual or customary brokerage commissions and other charges on their purchases and sales of Shares of the Fund in the secondary market, which are not reflected in the table or the example below.

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees	VictoryShares US Large Cap High Div Volatility Wtd ETF VictoryShares US Large Cap High Div Volatility Wtd ETF USD ($)
Shareholder Fees (fees paid directly from your investment)	none

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	VictoryShares US Large Cap High Div Volatility Wtd ETF VictoryShares US Large Cap High Div Volatility Wtd ETF
Management Fees	0.30%
Other Expenses	0.12%
Total Annual Fund Operating Expenses	0.42%
Fee Waivers/Expense Reimbursements	(0.07%)	[1]
Total Annual Fund Operating Expenses After Fee Waivers and Expense Reimbursements	0.35%	[1]

Example:

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The amounts shown reflect the fee waiver/expense reimbursement in place through the expiration date. Although your actual costs may be higher or lower, based upon these assumptions your costs would be:

Expense Example	1 Year	3 Years	5 Years	10 Years
VictoryShares US Large Cap High Div Volatility Wtd ETF | VictoryShares US Large Cap High Div Volatility Wtd ETF | USD ($)	36	128	228	523

Portfolio Turnover:

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover will generally indicate higher transaction costs resulting in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover was 52% of the average value of its portfolio.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by investing, under normal market conditions, at least 80% of its assets directly or indirectly in the securities included in the Nasdaq Victory US Large Cap High Dividend 100 Volatility Weighted Index (the "Index"), an unmanaged, volatility weighted index maintained exclusively by Nasdaq Inc. (the "Index Provider"). The Index Provider is not affiliated with the Fund or the Adviser.

The Index combines fundamental criteria with individual security risk control achieved through volatility weighting of individual securities. The Index follows a rules-based methodology to construct its constituent securities:

•  The Index universe begins with the stocks included in the Nasdaq Victory US Large Cap 500 Volatility Weighted Index, a volatility weighted index comprised of the 500 largest U.S. companies by market capitalization with positive earnings in each of the four most recent quarters.

•  The Index identifies the 100 highest dividend yielding stocks in the Nasdaq Victory US Large Cap 500 Volatility Weighted Index.

•  The 100 stocks are weighted based on their daily standard deviation (volatility) of daily price changes over the last 180 trading days. Stocks with lower volatility receive a higher weighting and stocks with higher volatility receive a lower weighting.

The Index is reconstituted every March and September (based on information as of the prior month-end) and is adjusted to limit exposure to any particular sector to 25%. The Index may include more than or fewer than 100 stocks depending on the number of companies meeting the Index's criteria. As of September 30, 2018, the Index had a market capitalization range from $4 billion to $360 billion.

The Fund generally seeks to track the returns of the Index before fees and expenses by employing a replication strategy that seeks to hold all the stocks in the Index.

Principal Risks of Investing in the Fund

The Fund's investments are subject to the following principal risks:

nEquity Risk — The value of the equity securities in which the Fund invests may decline in response to developments affecting individual companies and/or general economic conditions. A company's earnings or dividends may not increase as expected. Price changes may be temporary or last for extended periods.

nETF Structure Risks — The Fund is structured as an exchange-traded fund ("ETF") and as a result is subject to special risks, including:

nNot Individually Redeemable — The Fund's Shares ("Shares") are not individually redeemable and may be redeemed by the Fund at its net asset value per share ("NAV") only in large blocks known as "Creation Units." You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit. Alternatively, you may redeem your Shares by selling them on the secondary market at prevailing market prices

nTrading Issues — Trading in Shares on the Exchange (as defined below) may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. There is no guarantee that an active secondary market will develop for the Shares. In stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund's underlying portfolio holdings, which may lead to differences between the market price of the Shares and the underlying value of those Shares.

nMarket Price Variance Risk — The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a "bid-ask spread" charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a premium or discount to NAV.

nAuthorized Participants Concentration Risk — A limited number of financial institutions may be responsible for all or a significant portion of the creation and redemption activity for the Fund. If these firms exit the business or are unable or unwilling to process creation and/or redemption orders, Shares may trade at a premium or discount to NAV.

nIntraday Indicative Value (IIV) Risk — The Exchange intends to disseminate the approximate per share value of the Fund's published basket of securities ("Deposit Securities") every 15 seconds (the "intraday indicative value" or "IIV''). The IIV is not a "real-time" update of the NAV per share of the Fund because the IIV may not be calculated in the same manner as the NAV. For example, the calculation of the NAV may be subject to fair valuation at different prices than those used in the calculations of the IIV and, unlike the calculation of NAV, the IIV does not take into account Fund expenses. In addition, the IIV is based on the published Deposit Securities and not on the Fund's actual holdings.

nInvestment Strategy Risk — The Fund's dividend strategy may not be successful. Dividend paying stocks may fall out of favor relative to the overall market. In addition, the Index may not successfully identify companies that meet its objectives.

nLarge-Capitalization Stock Risk — The securities of large cap companies may underperform the securities of smaller cap companies or the market as a whole. The growth rate of larger, more established companies may lag those of smaller companies, especially during periods of economic expansion.

nLimited History of Operations — The Fund is a new ETF and, therefore, has a limited history of operations for investors to evaluate.

nPassive Investment Risk — The Fund is designed to track the Index and is not actively managed. The Fund will not buy or sell shares of an equity security due to current or projected performance of a security, industry or sector, unless that security is added to or removed, respectively, from the Index. The Fund does not, therefore, seek returns in excess of the Index, and does not attempt to take defensive positions or hedge against potential risks unless such defensive positions are also taken by the applicable Index.

nStock Market Risk — Overall stock market risks may affect the value of the Fund. Factors such as domestic and international economic growth and market conditions, interest rate levels and political events affect the securities markets.

nTracking Risk — The Fund's return may not match the return of the Index for a number of reasons, including: the Fund incurs operating expenses not applicable to the Index, and incurs costs in buying and selling securities; the Fund may not be fully invested at times; differences in the valuation of securities; and differences between the Fund's portfolio and the Index resulting from legal restrictions, cost, or liquidity constraints.

You may lose money by investing in the Fund. There is no guarantee that the Fund will achieve its objective. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Company (FDIC) or any other government agency.

By itself, the Fund does not constitute a complete investment plan and should be considered a long-term investment for investors who can afford to weather changes in the value of their investment.

VictoryShares US Small Cap High Div Volatility Wtd ETF

VictoryShares US Small Cap High Div Volatility Wtd ETF

Investment Objective

The Fund seeks to provide investment results that track the performance of the Nasdaq Victory US Small Cap High Dividend 100 Volatility Weighted Index before fees and expenses.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares ("Shares") of the Fund. Investors may incur usual or customary brokerage commissions and other charges on their purchases and sales of Shares of the Fund in the secondary market, which are not reflected in the table or the example below.

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees	VictoryShares US Small Cap High Div Volatility Wtd ETF VictoryShares US Small Cap High Div Volatility Wtd ETF USD ($)
Shareholder Fees (fees paid directly from your investment)	none

Annual Fund Operating Expenses (expenses that you pay each year a as a percentage of the value of your investment)

Annual Fund Operating Expenses	VictoryShares US Small Cap High Div Volatility Wtd ETF VictoryShares US Small Cap High Div Volatility Wtd ETF
Management Fees	0.30%
Other Expenses	0.15%
Total Annual Fund Operating Expenses	0.45%
Fee Waivers/Expense Reimbursements	(0.10%)	[1]
Total Annual Fund Operating Expenses After Fee Waivers and Expense Reimbursements	0.35%	[1]

Example:

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The amounts shown reflect the fee waiver/expense reimbursement in place through the expiration date. Although your actual costs may be higher or lower, based upon these assumptions your costs would be:

Expense Example	1 Year	3 Years	5 Years	10 Years
VictoryShares US Small Cap High Div Volatility Wtd ETF | VictoryShares US Small Cap High Div Volatility Wtd ETF | USD ($)	36	134	242	557

Portfolio Turnover:

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover will generally indicate higher transaction costs resulting in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover was 68% of the average value of its portfolio.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by investing, under normal market conditions, at least 80% of its assets directly or indirectly in the securities included in the Nasdaq Victory US Small Cap High Dividend 100 Volatility Weighted Index (the "Index"), an unmanaged, volatility weighted index maintained exclusively by Nasdaq Inc. (the "Index Provider"). The Index Provider is not affiliated with the Fund or the Adviser.

The Index combines fundamental criteria with individual security risk control achieved through volatility weighting of individual securities. The Index follows a rules-based methodology to construct its constituent securities:

•  The Index universe begins with the stocks included in the Nasdaq Victory US Small Cap 500 Volatility Weighted Index, a volatility weighted index comprised of the 500 largest U.S. companies with market capitalizations of less than $3 billion with positive earnings in each of the four most recent quarters.

•  The Index identifies the 100 highest dividend yielding stocks in the Nasdaq Victory US Small Cap 500 Volatility Weighted Index.

•  The 100 stocks are weighted based on their daily standard deviation (volatility) of daily price changes over the last 180 trading days. Stocks with lower volatility receive a higher weighting and stocks with higher volatility receive a lower weighting.

The Index is reconstituted every March and September (based on information as of the prior month-end) and is adjusted to limit exposure to any particular sector to 25%. The Index may include more than or fewer than 100 stocks depending on the number of companies meeting the Index's criteria. As of September 30, 2018, the Index had a market capitalization range from $365.5 million to $3.3 billion.

The Fund generally seeks to track the returns of the Index before fees and expenses by employing a replication strategy that seeks to hold all the stocks in the Index.

Principal Risks of Investing in the Fund

The Fund's investments are subject to the following principal risks:

nEquity Risk — The value of the equity securities in which the Fund invests may decline in response to developments affecting individual companies and/or general economic conditions. A company's earnings or dividends may not increase as expected. Price changes may be temporary or last for extended periods.

nETF Structure Risks — The Fund is structured as an exchange-traded fund ("ETF") and as a result is subject to special risks, including:

nNot Individually Redeemable — The Fund's Shares ("Shares") are not individually redeemable and may be redeemed by the Fund at its net asset value per share ("NAV") only in large blocks known as "Creation Units." You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit. Alternatively, you may redeem your Shares by selling them on the secondary market at prevailing market prices

nTrading Issues — Trading in Shares on the Exchange (as defined below) may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. There is no guarantee that an active secondary market will develop for the Shares. In stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund's underlying portfolio holdings, which may lead to differences between the market price of the Shares and the underlying value of those Shares.

nMarket Price Variance Risk — The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a "bid-ask spread" charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a premium or discount to NAV.

nAuthorized Participants Concentration Risk — A limited number of financial institutions may be responsible for all or a significant portion of the creation and redemption activity for the Fund. If these firms exit the business or are unable to process creation and/or redemption orders, Shares may trade at a premium or discount to NAV.

nIntraday Indicative Value (IIV) Risk — The Exchange intends to disseminate the approximate per share value of the Fund's published basket of securities ("Deposit Securities") every 15 seconds (the "intraday indicative value" or "IIV''). The IIV is not a "real-time" update of the NAV per share of the Fund because the IIV may not be calculated in the same manner as the NAV. For example, the calculation of the NAV may be subject to fair valuation at different prices than those used in the calculations of the IIV and, unlike the calculation of NAV, the IIV does not take into account Fund expenses. In addition, the IIV is based on the published Deposit Securities and not on the Fund's actual holdings.

nInvestment Strategy Risk — The Fund's dividend strategy may not be successful. Dividend paying stocks may fall out of favor relative to the overall market. In addition, the Index may not successfully identify companies that meet its objective.

nLimited History of Operations — The Fund is a new ETF and, therefore, has a limited history of operations for investors to evaluate.

nLiquidity Risk — In certain circumstances, such as the disruption of the orderly markets for the securities in which the Fund invests, the Fund might not be able to dispose of certain holdings quickly or at prices that represent true market value in the judgment of the Adviser. Markets for the securities in which the Fund invests may be disrupted by a number of events, including but not limited to economic crises, natural disasters, new legislation, or regulatory changes, and may prevent the Fund from limiting losses, realizing gains or achieving a high correlation with the Index.

nPassive Investment Risk — The Fund is designed to track the Index and is not actively managed. The Fund will not buy or sell shares of an equity security due to current or projected performance of a security, industry or sector, unless that security is added to or removed, respectively, from the Index. The Fund does not, therefore, seek returns in excess of the Index, and does not attempt to take defensive positions or hedge against potential risks unless such defensive positions are also taken by the applicable Index.

nSmaller Capitalization Stock Risk — The earnings and prospects of smaller-sized companies are more volatile than larger companies. Smaller-sized companies normally have a lower trading volume than larger companies, which may tend to make their market price fall more disproportionately than larger companies in response to selling pressures. Small-sized companies may have limited markets, product lines, or financial resources and lack management experience and may experience higher failure rates than larger companies.

nStock Market Risk — Overall stock market risks may affect the value of the Fund. Factors such as domestic and international economic growth and market conditions, interest rate levels and political events affect the securities markets.

nTracking Risks — The Fund's return may not match the return of the Index for a number of reasons, including: the Fund incurs operating expenses not applicable to the Index and incurs costs in buying and selling securities; the Fund may not be fully invested at times; differences in the valuation of securities; and differences between the Fund's portfolio and the Index resulting from legal restrictions, cost, or liquidity constraints.

You may lose money by investing in the Fund. There is no guarantee that the Fund will achieve its objective. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Company (FDIC) or any other government agency.

By itself, the Fund does not constitute a complete investment plan and should be considered a long-term investment for investors who can afford to weather changes in the value of their investment.

VictoryShares International High Div Volatility Wtd ETF

VictoryShares International High Div Volatility Wtd ETF

Investment Objective

The Fund seeks to provide investment results that track the performance of the Nasdaq Victory International High Dividend 100 Volatility Weighted Index before fees and expenses.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares ("Shares") of the Fund. Investors may incur usual or customary brokerage commissions and other charges on their purchases and sales of Shares of the Fund in the secondary market, which are not reflected in the table or the example below.

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees	VictoryShares International High Div Volatility Wtd ETF VictoryShares International High Div Volatility Wtd ETF USD ($)
Shareholder Fees (fees paid directly from your investment)	none

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	VictoryShares International High Div Volatility Wtd ETF VictoryShares International High Div Volatility Wtd ETF
Management Fees	0.40%
Other Expenses	0.20%
Total Annual Fund Operating Expenses	0.60%
Fee Waivers/Expense Reimbursements	(0.15%)	[1]
Total Annual Fund Operating Expenses After Fee Waivers and Expense Reimbursements	0.45%	[1]

Example:

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The amounts shown reflect the fee waiver/expense reimbursement in place through the expiration date. Although your actual costs may be higher or lower, based upon these assumptions your costs would be:

Expense Example	1 Year	3 Years	5 Years	10 Years
VictoryShares International High Div Volatility Wtd ETF | VictoryShares International High Div Volatility Wtd ETF | USD ($)	46	177	320	736

Portfolio Turnover:

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover will generally indicate higher transaction costs resulting in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover was 58% of the average value of its portfolio.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by investing, under normal market conditions, at least 80% of its assets directly or indirectly in the securities included in the Nasdaq Victory International High Dividend 100 Volatility Weighted Index (the "Index"), an unmanaged, volatility weighted index maintained exclusively by Nasdaq Inc. (the "Index Provider"). The Index Provider is not affiliated with the Fund or the Adviser.

The Index combines fundamental criteria with individual security risk control achieved through volatility weighting of individual securities. The Index follows a rules-based methodology to construct its constituent securities:

•  The Index universe begins with the stocks included in the Nasdaq Victory International 500 Volatility Weighted Index, a volatility weighted index comprised of the 500 largest foreign companies by market capitalization with positive earnings in each of the four most recent quarters.

•  The Index identifies the 100 highest dividend yielding stocks in the Nasdaq Victory International 500 Volatility Weighted Index.

•  The 100 stocks are weighted based on their daily standard deviation (volatility) of daily price changes over the last 180 trading days. Stocks with lower volatility receive a higher weighting and stocks with higher volatility receive a lower weighting.

The Index considers foreign companies to be those that are organized or domiciled in a developed country (excluding the U.S. and emerging markets) and whose stock principally trades on a foreign exchange. Representative developed markets include Canada, France, Germany, Japan, Hong Kong and Australia.

The Index is reconstituted every March and September (based on information as of the prior month-end) and is adjusted to limit exposure to any particular country to 20% and any particular sector to 25%. The Index may include more than or fewer than 100 stocks depending on the number of companies meeting the Index's criteria.

The Fund seeks to track the returns of the Index before fees and expenses by employing, under normal circumstances, a "sampling" process to invest in a representative sample of stocks included in the Index. The Fund's portfolio managers select these stocks using a statistical optimization process designed to produce investment characteristics that closely approximate those of the Index.

Principal Risks of Investing in the Fund

The Fund's investments are subject to the following principal risks:

nEquity Risk — The value of the equity securities in which the Fund invests may decline in response to developments affecting individual companies and/or general economic conditions. A company's earnings or dividends may not increase as expected. Price changes may be temporary or last for extended periods.

nETF Structure Risks — The Fund is structured as an exchange-traded fund ("ETF") and as a result is subject to special risks, including:

nNot Individually Redeemable — The Fund's Shares ("Shares") are not individually redeemable and may be redeemed by the Fund at its net asset value per share ("NAV") only in large blocks known as "Creation Units." You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit. Alternatively, you may redeem your Shares by selling them on the secondary market at prevailing market prices.

nTrading Issues — Trading in Shares on the Exchange (as defined below) may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. There is no guarantee that an active secondary market will develop for the Shares. In stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund's underlying portfolio holdings, which may lead to differences between the market price of the Shares and the underlying value of those Shares.

nMarket Price Variance Risk — The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a "bid-ask spread" charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a premium or discount to NAV.

nInternational Closed Market Trading Risk — Many of the Fund's underlying securities trade on foreign exchanges that are closed when the Exchange (as defined below) is open; consequently, events may transpire while such foreign exchanges are closed but the Exchange is open that may change the value of such underlying securities relative to their last quoted prices on such foreign exchanges. Because the Fund generally relies on the last quoted prices for such securities when calculating its NAV, such events may cause Shares to trade at a premium or discount to NAV.

nAuthorized Participants Concentration Risk — A limited number of financial institutions may be responsible for all or a significant portion of the creation and redemption activity for the Fund. If these firms exit the business or are unable to process creation and/or redemption orders, Shares may trade at a premium or discount to NAV.

nIntraday Indicative Value (IIV) Risk — The Exchange intends to disseminate the approximate per share value of the Fund's published basket of securities ("Deposit Securities") every 15 seconds (the "intraday indicative value" or "IIV''). The IIV is not a "real-time" update of the NAV per share of the Fund because the IIV may not be calculated in the same manner as the NAV. For example, the calculation of the NAV may be subject to fair valuation at different prices than those used in the calculations of the IIV and, unlike the calculation of NAV, the IIV does not take into account Fund expenses. The IIV calculations are based on local market prices and may not reflect events that occur subsequent to the local market's close which could affect premiums and discounts between the IIV and the market price of the Fund's share.

  In addition, the IIV is based on the published Deposit Securities and not on the Fund's actual holdings.

nForeign Investment Risks

nForeign Exposure Risk — Special risks associated with investments in foreign markets may include less liquidity, greater volatility, less developed or less efficient trading markets, lack of comprehensive company information, political instability and differing auditing and legal standards.

nCurrency Risk — The Fund's net asset value could decline as a result of changes in the exchange rates between foreign currencies and the US dollar. Additionally, certain foreign countries may impose restrictions on the ability of issuers of foreign securities to make payment of principal and interest to investors located outside the country, due to blockage of foreign currency exchanges or otherwise.

nInvestment Strategy Risk — The Fund's dividend strategy may not be successful. Dividend paying stocks may fall out of favor relative to the overall market. In addition, the Index may not successfully identify companies that meet its objective.

nLimited History of Operations — The Fund is a new ETF and, therefore, has a limited history of operations for investors to evaluate.

nPassive Investment Risk — The Fund is designed to track the Index and is not actively managed. The Fund will not buy or sell shares of an equity security due to current or projected performance of a security, industry or sector, unless that security is added to or removed, respectively, from the Index. The Fund does not, therefore, seek returns in excess of the Index, and does not attempt to take defensive positions or hedge against potential risks unless such defensive positions are also taken by the applicable Index.

nSampling Risk — The Fund's use of a representative sampling approach, if used, could result in its holding a smaller number of securities than are in the Index. As a result, an adverse development with an issuer or a small number of issuers of securities held by the Fund could result in a greater decline in NAV than would be the case if the Fund held all of the securities in the Index. To the extent the assets in the Fund are smaller, these risks will be greater.

nStock Market Risk — Overall stock market risks may affect the value of the Fund. Factors such as domestic and international economic growth and market conditions, interest rate levels and political events affect the securities markets.

nTracking Risk — The Fund's return may not match the return of the Index for a number of reasons, including: the Fund incurs operating expenses not applicable to the Index, and incurs costs in buying and selling securities; the Fund may not be fully invested at times; differences in the valuation of securities; and differences between the Fund's portfolio and the Index resulting from legal restrictions, cost, or liquidity constraints. The Fund's use of representative sampling may cause the tracking error to be higher than would be the case if the Fund purchased all of the securities in the Index.

You may lose money by investing in the Fund. There is no guarantee that the Fund will achieve its objective. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Company (FDIC) or any other government agency.

By itself, the Fund does not constitute a complete investment plan and should be considered a long-term investment for investors who can afford to weather changes in the value of their investment.

Principal Risks of Investing in the Fund

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund's investments are subject to the following principal risks:

nEquity Risk — The value of the equity securities in which the Fund invests may decline in response to developments affecting individual companies and/or general economic conditions. A company's earnings or dividends may not increase as expected. Price changes may be temporary or last for extended periods.

nETF Structure Risks — The Fund is structured as an exchange-traded fund ("ETF") and as a result is subject to special risks, including:

nNot Individually Redeemable — The Fund's Shares ("Shares") are not individually redeemable and may be redeemed by the Fund at its net asset value per share ("NAV") only in large blocks known as "Creation Units." You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit. Alternatively, you may redeem your Shares by selling them on the secondary market at prevailing market prices.

nTrading Issues — Trading in Shares on the Exchange (as defined below) may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. There is no guarantee that an active secondary market will develop for the Shares. In stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund's underlying portfolio holdings, which may lead to differences between the market price of the Shares and the underlying value of those Shares.

nMarket Price Variance Risk — The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a "bid-ask spread" charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a premium or discount to NAV.

nInternational Closed Market Trading Risk — Many of the Fund's underlying securities trade on foreign exchanges that are closed when the Exchange (as defined below) is open; consequently, events may transpire while such foreign exchanges are closed but the Exchange is open that may change the value of such underlying securities relative to their last quoted prices on such foreign exchanges. Because the Fund generally relies on the last quoted prices for such securities when calculating its NAV, such events may cause Shares to trade at a premium or discount to NAV.

nAuthorized Participants Concentration Risk — A limited number of financial institutions may be responsible for all or a significant portion of the creation and redemption activity for the Fund. If these firms exit the business or are unable to process creation and/or redemption orders, Shares may trade at a premium or discount to NAV.

nIntraday Indicative Value (IIV) Risk — The Exchange intends to disseminate the approximate per share value of the Fund's published basket of securities ("Deposit Securities") every 15 seconds (the "intraday indicative value" or "IIV''). The IIV is not a "real-time" update of the NAV per share of the Fund because the IIV may not be calculated in the same manner as the NAV. For example, the calculation of the NAV may be subject to fair valuation at different prices than those used in the calculations of the IIV and, unlike the calculation of NAV, the IIV does not take into account Fund expenses. The IIV calculations are based on local market prices and may not reflect events that occur subsequent to the local market's close which could affect premiums and discounts between the IIV and the market price of the Fund's share.

  In addition, the IIV is based on the published Deposit Securities and not on the Fund's actual holdings.

nForeign Investment Risks

nForeign Exposure Risk — Special risks associated with investments in foreign markets may include less liquidity, greater volatility, less developed or less efficient trading markets, lack of comprehensive company information, political instability and differing auditing and legal standards.

nCurrency Risk — The Fund's net asset value could decline as a result of changes in the exchange rates between foreign currencies and the US dollar. Additionally, certain foreign countries may impose restrictions on the ability of issuers of foreign securities to make payment of principal and interest to investors located outside the country, due to blockage of foreign currency exchanges or otherwise.

nInvestment Strategy Risk — The Fund's dividend strategy may not be successful. Dividend paying stocks may fall out of favor relative to the overall market. In addition, the Index may not successfully identify companies that meet its objective.

nLimited History of Operations — The Fund is a new ETF and, therefore, has a limited history of operations for investors to evaluate.

nPassive Investment Risk — The Fund is designed to track the Index and is not actively managed. The Fund will not buy or sell shares of an equity security due to current or projected performance of a security, industry or sector, unless that security is added to or removed, respectively, from the Index. The Fund does not, therefore, seek returns in excess of the Index, and does not attempt to take defensive positions or hedge against potential risks unless such defensive positions are also taken by the applicable Index.

nSampling Risk — The Fund's use of a representative sampling approach, if used, could result in its holding a smaller number of securities than are in the Index. As a result, an adverse development with an issuer or a small number of issuers of securities held by the Fund could result in a greater decline in NAV than would be the case if the Fund held all of the securities in the Index. To the extent the assets in the Fund are smaller, these risks will be greater.

nStock Market Risk — Overall stock market risks may affect the value of the Fund. Factors such as domestic and international economic growth and market conditions, interest rate levels and political events affect the securities markets.

nTracking Risk — The Fund's return may not match the return of the Index for a number of reasons, including: the Fund incurs operating expenses not applicable to the Index, and incurs costs in buying and selling securities; the Fund may not be fully invested at times; differences in the valuation of securities; and differences between the Fund's portfolio and the Index resulting from legal restrictions, cost, or liquidity constraints. The Fund's use of representative sampling may cause the tracking error to be higher than would be the case if the Fund purchased all of the securities in the Index.

You may lose money by investing in the Fund. There is no guarantee that the Fund will achieve its objective. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Company (FDIC) or any other government agency.

By itself, the Fund does not constitute a complete investment plan and should be considered a long-term investment for investors who can afford to weather changes in the value of their investment.

VictoryShares Emerging Market High Div Volatility Wtd ETF

VictoryShares Emerging Market High Div Volatility Wtd ETF

Investment Objective

The Fund seeks to provide investment results that track the performance of the Nasdaq Victory Emerging Market High Dividend 100 Volatility Weighted Index before fees and expenses.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares ("Shares") of the Fund. Investors may incur usual or customary brokerage commissions and other charges on their purchases and sales of Shares of the Fund in the secondary market, which are not reflected in the table or the example below.

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees	VictoryShares Emerging Market High Div Volatility Wtd ETF VictoryShares Emerging Market High Div Volatility Wtd ETF USD ($)
Shareholder Fees (fees paid directly from your investment)	none

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	VictoryShares Emerging Market High Div Volatility Wtd ETF VictoryShares Emerging Market High Div Volatility Wtd ETF
Management Fees	0.45%
Other Expenses	0.60%	[1]
Total Annual Fund Operating Expenses	1.05%
Fee Waivers/Expense Reimbursements	(0.55%)	[2]
Total Annual Fund Operating Expenses After Fee Waivers and Expense Reimbursements	0.50%	[2]

Example:

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The amounts shown reflect the fee waiver/expense reimbursement in place through the expiration date. Although your actual costs may be higher or lower, based upon these assumptions your costs would be:

Expense Example	1 Year	3 Years
VictoryShares Emerging Market High Div Volatility Wtd ETF | VictoryShares Emerging Market High Div Volatility Wtd ETF | USD ($)	51	279

Portfolio Turnover:

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover will generally indicate higher transaction costs resulting in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the Example, affect the Fund's performance. During the Fund's most recent fiscal period, the Fund's portfolio turnover rate was 52% of the average value of its portfolio.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by investing, under normal market conditions, at least 80% of its assets directly or indirectly in the securities included in the Nasdaq Victory Emerging Market High Dividend 100 Volatility Weighted Index (the "Index"), an unmanaged, volatility weighted index maintained exclusively by Nasdaq Inc. (the "Index Provider"). The Index Provider is not affiliated with the Fund or the Adviser.

The Index combines fundamental criteria with individual security risk control achieved through volatility weighting of individual securities. The Index follows a rules-based methodology to construct its constituent securities:

•  The Index universe begins with the stocks included in the Nasdaq Victory Emerging Market 500 Volatility Weighted Index, a volatility weighted index comprised of the 500 largest emerging market companies by market capitalization with positive earnings in each of the four most recent quarters.

•  The Index identifies the 100 highest dividend yielding stocks in the Nasdaq Victory Emerging Market 500 Volatility Weighted Index.

•  The 100 stocks are weighted based on their daily standard deviation (volatility) of daily price changes over the last 180 trading days. Stocks with lower volatility receive a higher weighting and stocks with higher volatility receive a lower weighting.

The Index considers emerging market companies to be those that are organized or domiciled in an emerging market country and whose stock principally trades on a foreign exchange. Emerging markets are generally those with a less-developed economy and per capita income significantly lower than the U.S. or other developed countries. Representative emerging market countries include China (Asia), Brazil (South America), Russia (Europe and Asia), India (Asia) and Egypt (Africa).

The Index is reconstituted every March and September (based on information as of the prior month-end) and is adjusted to limit exposure to any particular country to 20% and any particular sector to 25%. The Index may include more than or fewer than 100 stocks depending on the number of companies meeting the Index's criteria.

The Fund seeks to track the returns of the Index before fees and expenses by employing, under normal circumstances, a "sampling" process to invest in a representative sample of stocks included in the Index. The Fund's portfolio managers select these stocks using a statistical optimization process designed to produce investment characteristics that closely approximate those of the Index.

At times, the Fund may invest in other investment companies, including exchange traded funds ("ETFs"), in order to access a particular asset class or market.

Principal Risks of Investing in the Fund

The Fund's investments are subject to the following principal risks:

nEquity Risk — The value of the equity securities in which the Fund invests may decline in response to developments affecting individual companies and/or general economic conditions. A company's earnings or dividends may not increase as expected. Price changes may be temporary or last for extended periods.

nETF Structure Risks — The Fund is structured as an ETF and as a result is subject to special risks, including:

nNot Individually Redeemable — The Fund's Shares are not individually redeemable and may be redeemed by the Fund at its net asset value per share ("NAV") only in large blocks known as "Creation Units." You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit. Alternatively, you may redeem your Shares by selling them on the secondary market at prevailing market prices.

nTrading Issues — Trading in Shares on the Exchange (as defined below) may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. There is no guarantee that an active secondary market will develop for the Shares. In stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund's underlying portfolio holdings, which may lead to differences between the market price of the Shares and the underlying value of those Shares.

nMarket Price Variance Risk — The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a "bid-ask spread" charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a premium or discount to NAV.

nInternational Closed Market Trading Risk — Many of the Fund's underlying securities trade on foreign exchanges that are closed when the Exchange (as defined below) is open; consequently, events may transpire while such foreign exchanges are closed but the Exchange is open that may change the value of such underlying securities relative to their last quoted prices on such foreign exchanges. The IIV calculations are based on local market prices and may not reflect events that occur subsequent to the local market's close which could affect premiums and discounts between the IIV and the market price of the Shares. In addition, the IIV is based on the published Deposit Securities and not on the Fund's actual holdings.

nAuthorized Participants Concentration Risk — A limited number of financial institutions may be responsible for all or a significant portion of the creation and redemption activity for the Fund. If these firms exit the business or are unable or unwilling to process creation and/or redemption orders, Shares may trade at a premium or discount to NAV.

nIntraday Indicative Value (IIV) Risk — The Exchange intends to disseminate the approximate per share value of the Fund's published basket of securities ("Deposit Securities") every 15 seconds (the "intraday indicative value" or "IIV''). The IIV is not a "real-time" update of the NAV per share of the Fund because the IIV may not be calculated in the same manner as the NAV. For example, the calculation of the NAV may be subject to fair valuation at different prices than those used in the calculations of the IIV and, unlike the calculation of NAV, the IIV does not take into account Fund expenses. The IIV calculations are based on local market prices and may not reflect events that occur subsequent to the local market's close which could affect premiums and discounts between the IIV and the market price of the Fund's share. In addition, the IIV is based on the published Deposit Securities and not on the Fund's actual holdings.

nForeign Investment Risks

nForeign Exposure Risk — Special risks associated with investments in foreign markets may include less liquidity, greater volatility, less developed or less efficient trading markets, lack of comprehensive company information, political instability and differing auditing and legal standards.

nEmerging Markets Risk — All of the risks associated with investing in foreign securities are increased in connection with investments in emerging markets securities. Emerging market countries may have relatively unstable governments, weaker economies, and less-developed legal systems which do not protect securities holders. Emerging market economies may be based on only a few industries and security issuers may be more susceptible to economic weakness and more likely to default. Emerging market securities also tend to be less liquid.

nCurrency Risk — The Fund's net asset value could decline as a result of changes in the exchange rates between foreign currencies and the US dollar. Additionally, certain foreign countries may impose restrictions on the ability of issuers of foreign securities to make payment of principal and interest to investors located outside the country, due to blockage of foreign currency exchanges or otherwise.

nInvestment Company Risk — An investment company (including an ETF) or similar vehicle in which the Fund invests may not achieve its investment objective. Underlying investment vehicles are subject to investment advisory and other expenses, which will be indirectly paid by the Fund. Lack of liquidity in an ETF could result in an ETF being more volatile than the underlying portfolio of securities.

nInvestment Strategy Risk — The Fund's dividend strategy may not be successful. Dividend paying stocks may fall out of favor relative to the overall market. In addition, the Index may not successfully identify companies that meet its objective.

nLimited History of Operations — The Fund is a new ETF and, therefore, has a limited history of operations for investors to evaluate.

nLiquidity Risk — In certain circumstances, such as the disruption of the orderly markets for the securities in which the Fund invests, the Fund might not be able to dispose of certain holdings quickly or at prices that represent true market value in the judgment of the Adviser. Markets for the securities in which the Fund invests may be disrupted by a number of events, including but not limited to economic crises, natural disasters, new legislation, or regulatory changes, and may prevent the Fund from limiting losses, realizing gains or achieving a high correlation with the Index.

nPassive Investment Risk — The Fund is designed to track the Index and is not actively managed. The Fund will not buy or sell shares of an equity security due to current or projected performance of a security, industry or sector, unless that security is added to or removed, respectively, from the Index. The Fund does not, therefore, seek returns in excess of the Index, and does not attempt to take defensive positions or hedge against potential risks unless such defensive positions are also taken by the applicable Index.

nSampling Risk — The Fund's use of a representative sampling approach, if used, could result in its holding a smaller number of securities than are in the Index. As a result, an adverse development with an issuer or a small number of issuers of securities held by the Fund could result in a greater decline in NAV than would be the case if the Fund held all of the securities in the Index. To the extent the assets in the Fund are smaller, these risks will be greater.

nSmaller Company Risk — Small and mid-sized companies may be subject to a number of risks not associated with larger, more established companies, potentially making their stock prices more volatile and increasing the risk of loss. Smaller companies may have limited markets, product lines, or financial resources and lack management experience and may experience higher failure rates than larger companies.

nStock Market Risk — Overall stock market risks may affect the value of the Fund. Factors such as domestic and international economic growth and market conditions, interest rate levels and political events affect the securities markets.

nTracking Risk — The Fund's return may not match the return of the Index for a number of reasons, including: the Fund incurs operating expenses not applicable to the Index, and incurs costs in buying and selling securities; the Fund may not be fully invested at times; differences in the valuation of securities; and differences between the Fund's portfolio and the Index resulting from legal restrictions, cost, or liquidity constraints. The Fund's use of representative sampling may cause the tracking error to be higher than would be the case if the Fund purchased all of the securities in the Index.

You may lose money by investing in the Fund. There is no guarantee that the Fund will achieve its objective. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Company (FDIC) or any other government agency.

By itself, the Fund does not constitute a complete investment plan and should be considered a long-term investment for investors who can afford to weather changes in the value of their investment.

Principal Risks of Investing in the Fund

Risk Narrative [Text Block]

The Fund's investments are subject to the following principal risks:

nEquity Risk — The value of the equity securities in which the Fund invests may decline in response to developments affecting individual companies and/or general economic conditions. A company's earnings or dividends may not increase as expected. Price changes may be temporary or last for extended periods.

nETF Structure Risks — The Fund is structured as an ETF and as a result is subject to special risks, including:

nEmerging Markets Risk — All of the risks associated with investing in foreign securities are increased in connection with investments in emerging markets securities. Emerging market countries may have relatively unstable governments, weaker economies, and less-developed legal systems which do not protect securities holders. Emerging market economies may be based on only a few industries and security issuers may be more susceptible to economic weakness and more likely to default. Emerging market securities also tend to be less liquid.

nCurrency Risk — The Fund's net asset value could decline as a result of changes in the exchange rates between foreign currencies and the US dollar. Additionally, certain foreign countries may impose restrictions on the ability of issuers of foreign securities to make payment of principal and interest to investors located outside the country, due to blockage of foreign currency exchanges or otherwise.

nInvestment Company Risk — An investment company (including an ETF) or similar vehicle in which the Fund invests may not achieve its investment objective. Underlying investment vehicles are subject to investment advisory and other expenses, which will be indirectly paid by the Fund. Lack of liquidity in an ETF could result in an ETF being more volatile than the underlying portfolio of securities.

nInvestment Strategy Risk — The Fund's dividend strategy may not be successful. Dividend paying stocks may fall out of favor relative to the overall market. In addition, the Index may not successfully identify companies that meet its objective.

nLimited History of Operations — The Fund is a new ETF and, therefore, has a limited history of operations for investors to evaluate.

nLiquidity Risk — In certain circumstances, such as the disruption of the orderly markets for the securities in which the Fund invests, the Fund might not be able to dispose of certain holdings quickly or at prices that represent true market value in the judgment of the Adviser. Markets for the securities in which the Fund invests may be disrupted by a number of events, including but not limited to economic crises, natural disasters, new legislation, or regulatory changes, and may prevent the Fund from limiting losses, realizing gains or achieving a high correlation with the Index.

nPassive Investment Risk — The Fund is designed to track the Index and is not actively managed. The Fund will not buy or sell shares of an equity security due to current or projected performance of a security, industry or sector, unless that security is added to or removed, respectively, from the Index. The Fund does not, therefore, seek returns in excess of the Index, and does not attempt to take defensive positions or hedge against potential risks unless such defensive positions are also taken by the applicable Index.

nSampling Risk — The Fund's use of a representative sampling approach, if used, could result in its holding a smaller number of securities than are in the Index. As a result, an adverse development with an issuer or a small number of issuers of securities held by the Fund could result in a greater decline in NAV than would be the case if the Fund held all of the securities in the Index. To the extent the assets in the Fund are smaller, these risks will be greater.

nSmaller Company Risk — Small and mid-sized companies may be subject to a number of risks not associated with larger, more established companies, potentially making their stock prices more volatile and increasing the risk of loss. Smaller companies may have limited markets, product lines, or financial resources and lack management experience and may experience higher failure rates than larger companies.

nStock Market Risk — Overall stock market risks may affect the value of the Fund. Factors such as domestic and international economic growth and market conditions, interest rate levels and political events affect the securities markets.

nTracking Risk — The Fund's return may not match the return of the Index for a number of reasons, including: the Fund incurs operating expenses not applicable to the Index, and incurs costs in buying and selling securities; the Fund may not be fully invested at times; differences in the valuation of securities; and differences between the Fund's portfolio and the Index resulting from legal restrictions, cost, or liquidity constraints. The Fund's use of representative sampling may cause the tracking error to be higher than would be the case if the Fund purchased all of the securities in the Index.

You may lose money by investing in the Fund. There is no guarantee that the Fund will achieve its objective. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Company (FDIC) or any other government agency.

By itself, the Fund does not constitute a complete investment plan and should be considered a long-term investment for investors who can afford to weather changes in the value of their investment.

VictoryShares Dividend Accelerator ETF

VictoryShares Dividend Accelerator ETF

Investment Objective

The Fund seeks to provide investment results that track the performance of the Nasdaq Victory Dividend Accelerator Index before fees and expenses.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares ("Shares") of the Fund. Investors may incur usual or customary brokerage commissions and other charges on their purchases and sales of Shares of the Fund in the secondary market, which are not reflected in the table or the example below.

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees	VictoryShares Dividend Accelerator ETF VictoryShares Dividend Accelerator ETF USD ($)
Shareholder Fees (fees paid directly from your investment)	none

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	VictoryShares Dividend Accelerator ETF VictoryShares Dividend Accelerator ETF
Management Fees	0.30%
Other Expenses	0.37%
Total Annual Fund Operating Expenses	0.67%
Fee Waivers/Expense Reimbursements	(0.32%)	[1]
Total Annual Fund Operating Expenses After Fee Waivers and Expense Reimbursements	0.35%	[1]

Example:

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The amounts shown reflect the fee waiver/expense reimbursement in place through the expiration date. Although your actual costs may be higher or lower, based upon these assumptions your costs would be:

Expense Example	1 Year	3 Years
VictoryShares Dividend Accelerator ETF | VictoryShares Dividend Accelerator ETF | USD ($)	36	182

Portfolio Turnover:

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover will generally indicate higher transaction costs resulting in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the Example, affect the Fund's performance. During the most recent fiscal period, the Fund's portfolio turnover rate was 43% of the average value of its portfolio.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by investing, under normal market conditions, at least 80% of its assets in securities included in the Nasdaq Victory Dividend Accelerator Index (the "Index"). The Index utilizes a rules-based approach designed to identify dividend paying stocks with a higher likelihood of future dividend growth. The Index is maintained exclusively by Nasdaq Inc. (the "Index Provider"). The Index Provider is not affiliated with the Fund or the Adviser.

The companies eligible for inclusion in the Index are derived from its starting universe, the mid- to large-capitalization U.S. companies included in the Nasdaq US Large Mid Cap Index ("Parent Index"), an index maintained by the Index Provider. The Parent Index consists of those companies with market capitalizations representing the top 90% of the U.S. investable universe.

The Index screens companies in the Parent Index using a number of proprietary fundamental factors that have been identified by a quantitative multi-factor selection process to identify dividend paying companies with a higher probability of future dividend growth. Within this smaller set of companies, the Index weights the constituent securities using a methodology designed to maximize dividend growth, measured at a portfolio level, within established portfolio constraints (such as maximum weightings of index constituents and sectors). The Index is reconstituted every April and rebalanced quarterly (based on information as of the prior month-end).

The Fund generally seeks to track the returns of the Index before fees and expenses by employing a replication strategy that seeks to hold all the stocks in the Index in proportion to their weightings in the Index.

Principal Risks of Investing in the Fund

The Fund's investments are subject to the following principal risks:

nEquity Risk — The value of the equity securities in which the Fund invests may decline in response to developments affecting individual companies and/or general economic conditions. A company's earnings or dividends may not increase as expected. Price changes may be temporary or last for extended periods.

nETF Structure Risks — The Fund is structured as an exchange-traded fund ("ETF") and as a result is subject to special risks, including:

nNot Individually Redeemable — The Fund's Shares are not individually redeemable and may be redeemed by the Fund at its net asset value per share ("NAV") only in large blocks known as "Creation Units." You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit. Alternatively, you may redeem your Shares by selling them on the secondary market at prevailing market prices.

nTrading Issues — Trading in Shares on the Exchange (as defined below) may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. There is no guarantee that an active secondary market will develop for the Shares. In stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund's underlying portfolio holdings, which may lead to differences between the market price of the Shares and the underlying value of those Shares.

nMarket Price Variance Risk — The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a "bid-ask spread" charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a premium or discount to NAV.

nAuthorized Participants Concentration Risk — A limited number of financial institutions may be responsible for all or a significant portion of the creation and redemption activity for the Fund. If these firms exit the business or are unable to process creation and/or redemption orders, Shares may trade at a premium or discount to NAV.

nIntraday Indicative Value (IIV) Risk — The Exchange intends to disseminate the approximate per share value of the Fund's published basket of securities ("Deposit Securities") every 15 seconds (the "intraday indicative value" or "IIV''). The IIV is not a "real-time" update of the NAV per share of the Fund because the IIV may not be calculated in the same manner as the NAV. For example, the calculation of the NAV may be subject to fair valuation at different prices than those used in the calculations of the IIV and, unlike the calculation of NAV, the IIV does not take into account Fund expenses. In addition, the IIV is based on the published Deposit Securities and not on the Fund's actual holdings.

nInvestment Strategy Risk — The Fund's dividend strategy may not be successful. Dividend paying stocks may fall out of favor relative to the overall market or a company's dividends may not grow as projected. In addition, the Index may not successfully identify companies that meet its objective.

nLarge-Capitalization Stock Risk — The securities of large cap companies may underperform the securities of smaller cap companies or the market as a whole. The growth rate of larger, more established companies may lag those of smaller companies, especially during periods of economic expansion.

nLimited History of Operations — The Fund is a new ETF and, therefore, has a limited history of operations for investors to evaluate.

nPassive Investment Risk — The Fund is designed to track the Index and is not actively managed. The Fund will not buy or sell shares of an equity security due to current or projected performance of a security, industry or sector, unless that security is added to or removed, respectively, from the Index. The Fund does not, therefore, seek returns in excess of the Index, and does not attempt to take defensive positions or hedge against potential risks unless such defensive positions are also taken by the applicable Index.

nStock Market Risk — Overall stock market risks may affect the value of the Fund. Factors such as domestic and international economic growth and market conditions, interest rate levels and political events affect the securities markets.

nTracking Risk — The Fund's return may not match the return of the Index for a number of reasons, including: the Fund incurs operating expenses not applicable to the Index, and incurs costs in buying and selling securities; the Fund may not be fully invested at times; differences in the valuation of securities; and differences between the Fund's portfolio and the Index resulting from legal restrictions, cost, or liquidity constraints.

You may lose money by investing in the Fund. There is no guarantee that the Fund will achieve its objective. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Company (FDIC) or any other government agency.

Portfolio Turnover:

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover will generally indicate higher transaction costs resulting in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the Example, affect the Fund's performance. During the most recent fiscal period, the Fund's portfolio turnover rate was 26% of the average value of its portfolio.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by investing, under normal market conditions, at least 80% of its assets in securities included in the Nasdaq Victory US Multi-Factor Minimum Volatility Index (the "Index"). The Index utilizes a rules-based approach designed to generate investment returns with less volatility than the broader U.S. market. The Index is maintained exclusively by Nasdaq Inc. (the "Index Provider"). The Index Provider is not affiliated with the Fund or the Adviser.

The companies eligible for inclusion in the Index are derived from its starting universe, the mid- and large-capitalization U.S. companies included in the Nasdaq US Large Mid Cap Index ("Parent Index"), an index maintained by the Index Provider. The Parent Index consists of those U.S. companies with market caps representing the top 90% of the U.S. investable universe.

The Index Provider considers a company to be a U.S. company if it is economically tied to the U.S. In general, a company is treated as being economically tied to the U.S. if: (1) the company is incorporated and domiciled in the U.S., (2) the company makes public filings with U.S. securities regulators, and (3) the company's securities are listed on a U.S. exchange. In addition, the Index Provider treats companies that are incorporated in certain identified countries to benefit from tax, legal or other advantages, but which otherwise meet these requirements, as being economically tied to the U.S.

The Index is designed to construct a diversified portfolio with superior risk-adjusted returns by first ranking companies using a number of proprietary fundamental factors, such as dividend yield, sales growth and other financial metrics that have been identified by a quantitative multi-factor selection process to identify the companies that are most likely to outperform the broader U.S. market. The companies in the top 20% of the ranking are included in the Index. Within this smaller set of companies, the Index uses an optimization tool to weight the individual securities to minimize absolute volatility, measured at a portfolio level, within established portfolio constraints (such as minimum and maximum weightings of index constituents and sectors). The Index is reconstituted every April and October (based on information as of the prior month-end).

The Fund generally seeks to track the returns of the Index before fees and expenses by employing a replication strategy that seeks to hold all the stocks in the Index in proportion to their weightings in the Index.

Principal Risks of Investing in the Fund

The Fund's investments are subject to the following principal risks:

nEquity Risk — The value of the equity securities in which the Fund invests may decline in response to developments affecting individual companies and/or general economic conditions. A company's earnings or dividends may not increase as expected. Price changes may be temporary or last for extended periods.

nETF Structure Risks — The Fund is structured as an exchange-traded fund ("ETF") and as a result is subject to special risks, including:

nNot Individually Redeemable — The Fund's Shares are not individually redeemable and may be redeemed by the Fund at its net asset value per share ("NAV") only in large blocks known as "Creation Units." You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit. Alternatively, you may redeem your Shares by selling them on the secondary market at prevailing market prices.

nTrading Issues — Trading in Shares on the Exchange (as defined below) may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. There is no guarantee that an active secondary market will develop for the Shares. In stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund's underlying portfolio holdings, which may lead to differences between the market price of the Shares and the underlying value of those Shares.

nMarket Price Variance Risk — The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a "bid-ask spread" charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a premium or discount to NAV.

nAuthorized Participants Concentration Risk — A limited number of financial institutions may be responsible for all or a significant portion of the creation and redemption activity for the Fund. If these firms exit the business or are unable or unwilling to process creation and/or redemption orders, Shares may trade at a premium or discount to NAV.

nIntraday Indicative Value (IIV) Risk — The Exchange intends to disseminate the approximate per share value of the Fund's published basket of securities ("Deposit Securities") every 15 seconds (the "intraday indicative value" or "IIV''). The IIV is not a "real-time" update of the NAV per share of the Fund because the IIV may not be calculated in the same manner as the NAV. For example, the calculation of the NAV may be subject to fair valuation at different prices than those used in the calculations of the IIV and, unlike the calculation of NAV, the IIV does not take into account Fund expenses. In addition, the IIV is based on the published Deposit Securities and not on the Fund's actual holdings.

nInvestment Strategy Risk — The Index may not successfully identify companies that meet its objective. Although the Index is designed to minimize volatility compared to the Parent Index, there is no guarantee that this strategy will be successful.

nLarge-Capitalization Stock Risk — The securities of large cap companies may underperform the securities of smaller cap companies or the market as a whole. The growth rate of larger, more established companies may lag those of smaller companies, especially during periods of economic expansion.

nLimited History of Operations — The Fund is a new ETF and, therefore, has a limited history of operations for investors to evaluate.

nMid-Capitalization Stock Risk — Mid-sized companies may be subject to a number of risks not associated with larger, more established companies, potentially making their stock prices more volatile and increasing the risk of loss.

nPassive Investment Risk — The Fund is designed to track the Index and is not actively managed. The Fund will not buy or sell shares of an equity security due to current or projected performance of a security, industry or sector, unless that security is added to or removed, respectively, from the Index. The Fund does not, therefore, seek returns in excess of the Index, and does not attempt to take defensive positions or hedge against potential risks unless such defensive positions are also taken by the applicable Index.

nStock Market Risk — Overall stock market risks may affect the value of the Fund. Factors such as domestic and international economic growth and market conditions, interest rate levels and political events affect the securities markets.

nTracking Risk — The Fund's return may not match the return of the Index for a number of reasons, including: the Fund incurs operating expenses not applicable to the Index, and incurs costs in buying and selling securities; the Fund may not be fully invested at times; differences in the valuation of securities; and differences between the Fund's portfolio and the Index resulting from legal restrictions, cost, or liquidity constraints.

You may lose money by investing in the Fund. There is no guarantee that the Fund will achieve its objective. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Company (FDIC) or any other government agency.

By itself, the Fund does not constitute a complete investment plan and should be considered a long-term investment for investors who can afford to weather changes in the value of their investment.

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its investment objective by investing, under normal market conditions, at least 80% of its assets in securities included in the Nasdaq Victory US Multi-Factor Minimum Volatility Index (the "Index"). The Index utilizes a rules-based approach designed to generate investment returns with less volatility than the broader U.S. market. The Index is maintained exclusively by Nasdaq Inc. (the "Index Provider"). The Index Provider is not affiliated with the Fund or the Adviser.

The companies eligible for inclusion in the Index are derived from its starting universe, the mid- and large-capitalization U.S. companies included in the Nasdaq US Large Mid Cap Index ("Parent Index"), an index maintained by the Index Provider. The Parent Index consists of those U.S. companies with market caps representing the top 90% of the U.S. investable universe.

The Index Provider considers a company to be a U.S. company if it is economically tied to the U.S. In general, a company is treated as being economically tied to the U.S. if: (1) the company is incorporated and domiciled in the U.S., (2) the company makes public filings with U.S. securities regulators, and (3) the company's securities are listed on a U.S. exchange. In addition, the Index Provider treats companies that are incorporated in certain identified countries to benefit from tax, legal or other advantages, but which otherwise meet these requirements, as being economically tied to the U.S.

The Index is designed to construct a diversified portfolio with superior risk-adjusted returns by first ranking companies using a number of proprietary fundamental factors, such as dividend yield, sales growth and other financial metrics that have been identified by a quantitative multi-factor selection process to identify the companies that are most likely to outperform the broader U.S. market. The companies in the top 20% of the ranking are included in the Index. Within this smaller set of companies, the Index uses an optimization tool to weight the individual securities to minimize absolute volatility, measured at a portfolio level, within established portfolio constraints (such as minimum and maximum weightings of index constituents and sectors). The Index is reconstituted every April and October (based on information as of the prior month-end).

The Fund generally seeks to track the returns of the Index before fees and expenses by employing a replication strategy that seeks to hold all the stocks in the Index in proportion to their weightings in the Index.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund's investments are subject to the following principal risks:

nEquity Risk — The value of the equity securities in which the Fund invests may decline in response to developments affecting individual companies and/or general economic conditions. A company's earnings or dividends may not increase as expected. Price changes may be temporary or last for extended periods.

Portfolio Turnover:

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover will generally indicate higher transaction costs resulting in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the Example, affect the Fund's performance. Because the Fund has not yet commenced investment operations, no portfolio turnover information is available at this time.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by investing, under normal market conditions, at least 80% of its assets in securities included in the Nasdaq Victory Global Multi-Factor Minimum Volatility Index (the "Index"). The Index utilizes a rules-based approach designed to generate investment returns with less volatility than the broader global market. The Index is maintained exclusively by Nasdaq Inc. (the "Index Provider"). The Index Provider is not affiliated with the Fund or the Adviser.

The companies eligible for inclusion in the Index are derived from its starting universe, the mid- to large-capitalization companies included in the Nasdaq Global Large Mid Cap Index ("Parent Index"), an index maintained by the Index Provider. The Parent Index consists of those companies with market capitalizations representing the top 90% of the investable universe in each developed market (including the U.S.) and each emerging market represented in the Parent Index.

The Index is designed to construct a diversified portfolio with superior risk-adjusted returns by first screening companies using a number of proprietary fundamental factors, such as dividend yield, sales growth and other financial metrics that have been identified by a quantitative multi-factor selection process to identify the companies that are most likely to outperform the broader global market. The companies in the top 20% of the ranking are included in the Index. Within this smaller set of companies, the Index weights the individual securities to minimize absolute volatility, measured at a portfolio level, within established portfolio constraints (such as minimum and maximum weightings of index constituents, sectors and countries).

In constructing the Parent Index, the Index Provider assigns a company to a particular country if it is economically tied to that country. In general, a company is treated as economically tied to a particular country if two or more of the following are true: (1) the company is incorporated in the country, (2) the company's domicile (i.e., location of its headquarters or principal executive office) is in the country, and (3) the company's securities are listed on the country's primary exchange. In addition, the Index Provider treats a company that is incorporated in certain identified countries to benefit from tax, legal or other advantages as being economically tied to the country of its primary exchange listing. In the event a different country is identified for each of these categories for a company, the company is treated as being economically tied to the country of its primary exchange listing. The Index is reconstituted every April and October (based on information as of the prior month-end).

The countries represented by the Index will change over time based on changes in the countries comprising the Parent Index and changes in the constituent securities selected for the Index based on application of the Index Provider's proprietary model. As of the date of this prospectus, the Index included companies from 25 developed countries and 20 emerging market countries.

The Fund seeks to track the returns of the Index before fees and expenses by employing, under normal circumstances, a "sampling" process to invest in a representative sample of stocks included in the Index or other securities investments that have economic characteristics that are substantially identical to the economic characteristics of such component securities. The Fund's portfolio managers select these stocks using a statistical optimization process designed to produce investment characteristics that closely approximate those of the Index.

Principal Risks of Investing in the Fund

The Fund's investments are subject to the following principal risks:

nEquity Risk — The value of the equity securities in which the Fund invests may decline in response to developments affecting individual companies and/or general economic conditions. A company's earnings or dividends may not increase as expected. Price changes may be temporary or last for extended periods.

nETF Structure Risks — The Fund is structured as an exchange-traded fund ("ETF") and as a result is subject to special risks, including:

nNot Individually Redeemable —The Fund's Shares are not individually redeemable and may be redeemed by the Fund at its net asset value per share ("NAV") only in large blocks known as "Creation Units." You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit. Alternatively, you may redeem your Shares by selling them on the secondary market at prevailing market prices.

nTrading Issues —Trading in Shares on the Exchange (as defined below) may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. There is no guarantee that an active secondary market will develop for the Shares. In stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund's underlying portfolio holdings, which may lead to differences between the market price of the Shares and the underlying value of those Shares.

nMarket Price Variance Risk —The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a "bid-ask spread" charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a premium or discount to NAV.

nInternational Closed Market Trading Risk —Many of the Fund's underlying securities trade on foreign exchanges that are closed when the Exchange (as defined below) is open; consequently, events may transpire while such foreign exchanges are closed but the Exchange is open that may change the value of such underlying securities relative to their last quoted prices on such foreign exchanges. Because the Fund generally relies on the last quoted prices for such securities when calculating its NAV, such events may cause Shares to trade at a premium or discount to NAV.

nAuthorized Participants Concentration Risk —A limited number of financial institutions may be responsible for all or a significant portion of the creation and redemption activity for the Fund. If these firms exit the business or are unable or unwilling to process creation and/or redemption orders, Shares may trade at a premium or discount to NAV.

nIntraday Indicative Value (IIV) Risk —The Exchange intends to disseminate the approximate per share value of the Fund's published basket of securities ("Deposit Securities") every 15 seconds (the "intraday indicative value" or "IIV''). The IIV is not a "real-time" update of the NAV per share of the Fund because the IIV may not be calculated in the same manner as the NAV. For example, the calculation of the NAV may be subject to fair valuation at different prices than those used in the calculations of the IIV and, unlike the calculation of NAV, the IIV does not take into account Fund expenses. The IIV calculations are based on local market prices and may not reflect events that occur subsequent to the local market's close which could affect premiums and discounts between the IIV and the market price of the Fund's share. In addition, the IIV is based on the published Deposit Securities and not on the Fund's actual holdings.

nForeign Investment Risks

nForeign Exposure Risk —Special risks associated with investments in foreign markets may include less liquidity, greater volatility, less developed or less efficient trading markets, lack of comprehensive company information, political instability and differing auditing and legal standards.

nEmerging Markets Risk —All of the risks associated with investing in foreign securities are increased in connection with investments in emerging markets securities. Emerging market countries may have relatively unstable governments, weaker economies, and less-developed legal systems which do not protect securities holders. Emerging market economies may be based on only a few industries and security issuers may be more susceptible to economic weakness and more likely to default. Emerging market securities also tend to be less liquid.

nCurrency Risk —The Fund's net asset value could decline as a result of changes in the exchange rates between foreign currencies and the US dollar. Additionally, certain foreign countries may impose restrictions on the ability of issuers of foreign securities to make payment of principal and interest to investors located outside the country, due to blockage of foreign currency exchanges or otherwise.

nInvestment Strategy Risk — The Index may not successfully identify companies that meet its objective. Although the Index is designed to minimize volatility compared to the Parent Index, there is no guarantee that this strategy will be successful.

nLarge-Capitalization Stock Risk — The securities of large cap companies may underperform the securities of smaller cap companies or the market as a whole. The growth rate of larger, more established companies may lag those of smaller companies, especially during periods of economic expansion.

nLimited History of Operations — The Fund is a new ETF and, therefore, has a limited history of operations for investors to evaluate.

nMid-Capitalization Stock Risk — Mid-sized companies may be subject to a number of risks not associated with larger, more established companies, potentially making their stock prices more volatile and increasing the risk of loss.

nPassive Investment Risk — The Fund is designed to track the Index and is not actively managed. The Fund will not buy or sell shares of an equity security due to current or projected performance of a security, industry or sector, unless that security is added to or removed, respectively, from the Index. The Fund does not, therefore, seek returns in excess of the Index, and does not attempt to take defensive positions or hedge against potential risks unless such defensive positions are also taken by the applicable Index.

nSampling Risk — The Fund's use of a representative sampling approach could result in its holding a smaller number of securities than are in the Index. As a result, an adverse development with an issuer of securities held by the Fund could result in a greater decline in NAV than would be the case if the Fund held all of the securities in the Index. To the extent the assets in the Fund are smaller, these risks will be greater.

nStock Market Risk — Overall stock market risks may affect the value of the Fund. Factors such as domestic and international economic growth and market conditions, interest rate levels and political events affect the securities markets.

nTracking Risk — The Fund's return may not match the return of the Index for a number of reasons, including: the Fund incurs operating expenses not applicable to the Index, and incurs costs in buying and selling securities; the Fund may not be fully invested at times; differences in the valuation of securities; and differences between the Fund's portfolio and the Index resulting from legal restrictions, cost, or liquidity constraints. The Fund's use of representative sampling may cause the tracking error to be higher than would be the case if the Fund purchased all of the securities in the Index.

You may lose money by investing in the Fund. There is no guarantee that the Fund will achieve its objective. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Company (FDIC) or any other government agency.

By itself, the Fund does not constitute a complete investment plan and should be considered a long-term investment for investors who can afford to weather changes in the value of their investment.

These costs, which are not reflected in annual Fund operating expenses or in the Example, affect the Fund's performance. Because the Fund has not yet commenced investment operations, no portfolio turnover information is available at this time.

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its investment objective by investing, under normal market conditions, at least 80% of its assets in securities included in the Nasdaq Victory Global Multi-Factor Minimum Volatility Index (the "Index"). The Index utilizes a rules-based approach designed to generate investment returns with less volatility than the broader global market. The Index is maintained exclusively by Nasdaq Inc. (the "Index Provider"). The Index Provider is not affiliated with the Fund or the Adviser.

The companies eligible for inclusion in the Index are derived from its starting universe, the mid- to large-capitalization companies included in the Nasdaq Global Large Mid Cap Index ("Parent Index"), an index maintained by the Index Provider. The Parent Index consists of those companies with market capitalizations representing the top 90% of the investable universe in each developed market (including the U.S.) and each emerging market represented in the Parent Index.

The Index is designed to construct a diversified portfolio with superior risk-adjusted returns by first screening companies using a number of proprietary fundamental factors, such as dividend yield, sales growth and other financial metrics that have been identified by a quantitative multi-factor selection process to identify the companies that are most likely to outperform the broader global market. The companies in the top 20% of the ranking are included in the Index. Within this smaller set of companies, the Index weights the individual securities to minimize absolute volatility, measured at a portfolio level, within established portfolio constraints (such as minimum and maximum weightings of index constituents, sectors and countries).

In constructing the Parent Index, the Index Provider assigns a company to a particular country if it is economically tied to that country. In general, a company is treated as economically tied to a particular country if two or more of the following are true: (1) the company is incorporated in the country, (2) the company's domicile (i.e., location of its headquarters or principal executive office) is in the country, and (3) the company's securities are listed on the country's primary exchange. In addition, the Index Provider treats a company that is incorporated in certain identified countries to benefit from tax, legal or other advantages as being economically tied to the country of its primary exchange listing. In the event a different country is identified for each of these categories for a company, the company is treated as being economically tied to the country of its primary exchange listing. The Index is reconstituted every April and October (based on information as of the prior month-end).

The countries represented by the Index will change over time based on changes in the countries comprising the Parent Index and changes in the constituent securities selected for the Index based on application of the Index Provider's proprietary model. As of the date of this prospectus, the Index included companies from 25 developed countries and 20 emerging market countries.

The Fund seeks to track the returns of the Index before fees and expenses by employing, under normal circumstances, a "sampling" process to invest in a representative sample of stocks included in the Index or other securities investments that have economic characteristics that are substantially identical to the economic characteristics of such component securities. The Fund's portfolio managers select these stocks using a statistical optimization process designed to produce investment characteristics that closely approximate those of the Index.

Principal Risks of Investing in the Fund

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund's investments are subject to the following principal risks:

nEquity Risk — The value of the equity securities in which the Fund invests may decline in response to developments affecting individual companies and/or general economic conditions. A company's earnings or dividends may not increase as expected. Price changes may be temporary or last for extended periods.

nETF Structure Risks — The Fund is structured as an exchange-traded fund ("ETF") and as a result is subject to special risks, including:

nNot Individually Redeemable —The Fund's Shares are not individually redeemable and may be redeemed by the Fund at its net asset value per share ("NAV") only in large blocks known as "Creation Units." You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit. Alternatively, you may redeem your Shares by selling them on the secondary market at prevailing market prices.

nTrading Issues —Trading in Shares on the Exchange (as defined below) may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. There is no guarantee that an active secondary market will develop for the Shares. In stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund's underlying portfolio holdings, which may lead to differences between the market price of the Shares and the underlying value of those Shares.

nMarket Price Variance Risk —The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a "bid-ask spread" charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a premium or discount to NAV.

nInternational Closed Market Trading Risk —Many of the Fund's underlying securities trade on foreign exchanges that are closed when the Exchange (as defined below) is open; consequently, events may transpire while such foreign exchanges are closed but the Exchange is open that may change the value of such underlying securities relative to their last quoted prices on such foreign exchanges. Because the Fund generally relies on the last quoted prices for such securities when calculating its NAV, such events may cause Shares to trade at a premium or discount to NAV.

nAuthorized Participants Concentration Risk —A limited number of financial institutions may be responsible for all or a significant portion of the creation and redemption activity for the Fund. If these firms exit the business or are unable or unwilling to process creation and/or redemption orders, Shares may trade at a premium or discount to NAV.

nIntraday Indicative Value (IIV) Risk —The Exchange intends to disseminate the approximate per share value of the Fund's published basket of securities ("Deposit Securities") every 15 seconds (the "intraday indicative value" or "IIV''). The IIV is not a "real-time" update of the NAV per share of the Fund because the IIV may not be calculated in the same manner as the NAV. For example, the calculation of the NAV may be subject to fair valuation at different prices than those used in the calculations of the IIV and, unlike the calculation of NAV, the IIV does not take into account Fund expenses. The IIV calculations are based on local market prices and may not reflect events that occur subsequent to the local market's close which could affect premiums and discounts between the IIV and the market price of the Fund's share. In addition, the IIV is based on the published Deposit Securities and not on the Fund's actual holdings.

nForeign Investment Risks

nForeign Exposure Risk —Special risks associated with investments in foreign markets may include less liquidity, greater volatility, less developed or less efficient trading markets, lack of comprehensive company information, political instability and differing auditing and legal standards.

nEmerging Markets Risk —All of the risks associated with investing in foreign securities are increased in connection with investments in emerging markets securities. Emerging market countries may have relatively unstable governments, weaker economies, and less-developed legal systems which do not protect securities holders. Emerging market economies may be based on only a few industries and security issuers may be more susceptible to economic weakness and more likely to default. Emerging market securities also tend to be less liquid.

nCurrency Risk —The Fund's net asset value could decline as a result of changes in the exchange rates between foreign currencies and the US dollar. Additionally, certain foreign countries may impose restrictions on the ability of issuers of foreign securities to make payment of principal and interest to investors located outside the country, due to blockage of foreign currency exchanges or otherwise.

nInvestment Strategy Risk — The Index may not successfully identify companies that meet its objective. Although the Index is designed to minimize volatility compared to the Parent Index, there is no guarantee that this strategy will be successful.

nLarge-Capitalization Stock Risk — The securities of large cap companies may underperform the securities of smaller cap companies or the market as a whole. The growth rate of larger, more established companies may lag those of smaller companies, especially during periods of economic expansion.

nLimited History of Operations — The Fund is a new ETF and, therefore, has a limited history of operations for investors to evaluate.

nMid-Capitalization Stock Risk — Mid-sized companies may be subject to a number of risks not associated with larger, more established companies, potentially making their stock prices more volatile and increasing the risk of loss.

nPassive Investment Risk — The Fund is designed to track the Index and is not actively managed. The Fund will not buy or sell shares of an equity security due to current or projected performance of a security, industry or sector, unless that security is added to or removed, respectively, from the Index. The Fund does not, therefore, seek returns in excess of the Index, and does not attempt to take defensive positions or hedge against potential risks unless such defensive positions are also taken by the applicable Index.

nSampling Risk — The Fund's use of a representative sampling approach could result in its holding a smaller number of securities than are in the Index. As a result, an adverse development with an issuer of securities held by the Fund could result in a greater decline in NAV than would be the case if the Fund held all of the securities in the Index. To the extent the assets in the Fund are smaller, these risks will be greater.

nStock Market Risk — Overall stock market risks may affect the value of the Fund. Factors such as domestic and international economic growth and market conditions, interest rate levels and political events affect the securities markets.

nTracking Risk — The Fund's return may not match the return of the Index for a number of reasons, including: the Fund incurs operating expenses not applicable to the Index, and incurs costs in buying and selling securities; the Fund may not be fully invested at times; differences in the valuation of securities; and differences between the Fund's portfolio and the Index resulting from legal restrictions, cost, or liquidity constraints. The Fund's use of representative sampling may cause the tracking error to be higher than would be the case if the Fund purchased all of the securities in the Index.

You may lose money by investing in the Fund. There is no guarantee that the Fund will achieve its objective. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Company (FDIC) or any other government agency.

By itself, the Fund does not constitute a complete investment plan and should be considered a long-term investment for investors who can afford to weather changes in the value of their investment.

A company's earnings or dividends may not increase as expected. Price changes may be temporary or last for extended periods.

nETF Structure Risks — The Fund is structured as an exchange-traded fund ("ETF") and as a result is subject to special risks, including:

nNot Individually Redeemable —The Fund's Shares are not individually redeemable and may be redeemed by the Fund at its net asset value per share ("NAV") only in large blocks known as "Creation Units." You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit. Alternatively, you may redeem your Shares by selling them on the secondary market at prevailing market prices.

nTrading Issues — Trading in Shares on the Exchange (as defined below) may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. There is no guarantee that an active secondary market will develop for the Shares. In stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund's underlying portfolio holdings, which may lead to differences between the market price of the Shares and the underlying value of those Shares.

nMarket Price Variance Risk —The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a "bid-ask spread" charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a premium or discount to NAV.

nInternational Closed Market Trading Risk —Most of the Fund's underlying securities trade on foreign exchanges that are closed when the Exchange (as defined below) is open; consequently, events may transpire while such foreign exchanges are closed but the Exchange is open that may change the value of such underlying securities relative to their last quoted prices on such foreign exchanges. Because the Fund generally relies on the last quoted prices for such securities when calculating its NAV, such events may cause Shares to trade at a premium or discount to NAV.

nAuthorized Participants Concentration Risk —A limited number of financial institutions may be responsible for all or a significant portion of the creation and redemption activity for the Fund. If these firms exit the business or are unable or unwilling to process creation and/or redemption orders, Shares may trade at a premium or discount to NAV.

nIntraday Indicative Value (IIV) Risk —The Exchange intends to disseminate the approximate per share value of the Fund's published basket of securities ("Deposit Securities") every 15 seconds (the "intraday indicative value" or "IIV''). The IIV is not a "real-time" update of the NAV per share of the Fund because the IIV may not be calculated in the same manner as the NAV. For example, the calculation of the NAV may be subject to fair valuation at different prices than those used in the calculations of the IIV and, unlike the calculation of NAV, the IIV does not take into account Fund expenses. The IIV calculations are based on local market prices and may not reflect events that occur subsequent to the local market's close which could affect premiums and discounts between the IIV and the market price of the Fund's share. In addition, the IIV is based on the published Deposit Securities and not on the Fund's actual holdings.

nForeign Investment Risks

nForeign Exposure Risk —Special risks associated with investments in foreign markets may include less liquidity, greater volatility, less developed or less efficient trading markets, lack of comprehensive company information, political instability and differing auditing and legal standards.

nCurrency Risk —The Fund's net asset value could decline as a result of changes in the exchange rates between foreign currencies and the US dollar. Additionally, certain foreign countries may impose restrictions on the ability of issuers of foreign securities to make payment of principal and interest to investors located outside the country, due to blockage of foreign currency exchanges or otherwise.

nInvestment Strategy Risk — The Index may not successfully identify companies that meet its objective. Although the Index is designed to minimize volatility compared to the Parent Index, there is no guarantee that this strategy will be successful.

nLarge-Capitalization Stock Risk — The securities of large cap companies may underperform the securities of smaller cap companies or the market as a whole. The growth rate of larger, more established companies may lag those of smaller companies, especially during periods of economic expansion.

nLimited History of Operations — The Fund is a new ETF and, therefore, has a limited history of operations for investors to evaluate.

nMid-Capitalization Stock Risk — Mid-sized companies may be subject to a number of risks not associated with larger, more established companies, potentially making their stock prices more volatile and increasing the risk of loss.

nPassive Investment Risk — The Fund is designed to track the Index and is not actively managed. The Fund will not buy or sell shares of an equity security due to current or projected performance of a security, industry or sector, unless that security is added to or removed, respectively, from the Index. The Fund does not, therefore, seek returns in excess of the Index, and does not attempt to take defensive positions or hedge against potential risks unless such defensive positions are also taken by the applicable Index.

nSampling Risk — The Fund's use of a representative sampling approach could result in its holding a smaller number of securities than are in the Index. As a result, an adverse development with an issuer of securities held by the Fund could result in a greater decline in NAV than would be the case if the Fund held all of the securities in the Index. To the extent the assets in the Fund are smaller, these risks will be greater.

nStock Market Risk — Overall stock market risks may affect the value of the Fund. Factors such as domestic and international economic growth and market conditions, interest rate levels and political events affect the securities markets.

nTracking Risk — The Fund's return may not match the return of the Index for a number of reasons, including: the Fund incurs operating expenses not applicable to the Index, and incurs costs in buying and selling securities; the Fund may not be fully invested at times; differences in the valuation of securities; and differences between the Fund's portfolio and the Index resulting from legal restrictions, cost, or liquidity constraints. The Fund's use of representative sampling may cause the tracking error to be higher than would be the case if the Fund purchased all of the securities in the Index.

You may lose money by investing in the Fund. There is no guarantee that the Fund will achieve its objective. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Company (FDIC) or any other government agency.

By itself, the Fund does not constitute a complete investment plan and should be considered a long-term investment for investors who can afford to weather changes in the value of their investment.

VictoryShares US 500 Enhanced Volatility Wtd ETF

Investment Objective

The Fund seeks to provide investment results that track the performance of the Nasdaq Victory US Large Cap 500 Long/Cash Volatility Weighted Index before fees and expenses.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares ("Shares") of the Fund. Investors may incur usual or customary brokerage commissions and other charges on their purchases and sales of Shares of the Fund in the secondary market, which are not reflected in the table or the example below.

Example:

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The amounts shown reflect the fee waiver/expense reimbursement in placed through the expiration date. Although your actual costs may be higher or lower, based upon these assumptions your costs would be:

Expense Example	1 Year	3 Years	5 Years	10 Years
VictoryShares US 500 Enhanced Volatility Wtd ETF | VictoryShares US 500 Enhanced Volatility Wtd ETF | USD ($)	36	126	224	512

Portfolio Turnover:

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover will generally indicate higher transaction costs resulting in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover was 37% of the average value of its portfolio.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by investing, under normal market conditions, at least 80% of its assets directly or indirectly in the securities included in the Nasdaq Victory US Large Cap 500 Long/Cash Volatility Weighted Index (the "Index"), an unmanaged, volatility weighted index maintained exclusively by Nasdaq Inc. (the "Index Provider"). The Index Provider is not affiliated with the Fund or the Adviser.

The Index combines fundamental criteria with individual security risk control achieved through volatility weighting of individual securities. In accordance with a rules-based mathematical formula, the Index tactically reduces its exposure to the equity markets during periods of significant market decline and reallocates to stocks when market prices have either further declined or rebounded. The term "Enhanced" in the Fund's name refers to a feature of the Index that is designed to enhance risk-adjusted returns while attempting to minimize downside market risk through defensive positioning, as described below.

The Index follows a rules-based methodology to construct its constituent securities:

•  The Index universe begins with all publicly traded U.S. stocks and then screens for all companies with positive earnings in each of the four most recent quarters.

•  The Index identifies the 500 largest U.S. stocks by market capitalization measured at the time the Index's constituent securities are determined.

•  The 500 stocks are weighted based on their daily standard deviation (volatility) of daily price changes over the last 180 trading days. Stocks with lower volatility receive a higher weighting and stocks with higher volatility receive a lower weighting.

The Index is reconstituted every March and September (based on information as of the prior month-end) and is adjusted to limit exposure to any particular sector to 25%. The Index may include more than or fewer than 500 stocks depending on the number of companies meeting the Index's criteria. As of September 30, 2018, the Index had a market capitalization range from $2.3 billion to $1.1 trillion.

The Index follows a mathematical index construction process designed to limit risk during periods of significant (non-normal) market decline by reducing its exposure to the equity market. Market decline is measured by reference to the Nasdaq Victory US Large Cap 500 Volatility Weighted Index ("Reference Index"), which is composed of the same securities as in the Index but without any allocation to cash.

During a period of significant market decline, defined as a decline of 10% or more from the Reference Index's all-time daily high closing value compared to its most recent month-end closing value, the Index's exposure to the market may be as low as 25% depending on the magnitude and duration of such decline.

If the month-end value of the Reference Index declines 10% or more from its all-time closing high, the Index will reallocate 75% of the stocks included in the Index to cash or cash equivalents.

The Index will reallocate to stocks as follows:

•  The Index will return to being 100% allocated to stocks if the month-end closing value of the stocks in the Reference Index returns to a level that is less than a 10% decline from its all-time daily high closing value.

•  If the Reference Index declines by 20% (or more) from its all-time daily high closing value as measured at month-end, 25% of the Index will reallocate to the stocks of the Reference Index at their current securities weightings.

•  If the Reference Index declines by 30% (or more) from its all-time daily high closing value as measured at month-end, another 25% of the Index will reallocate to the stocks of the Reference Index at their current securities weightings.

•  If the Reference Index declines by 40% (or more) from its all-time daily high closing value as measured at month-end, the remaining 25% of the Index will reallocated to the stocks of the Reference Index at their current securities weighting and the Index will then be 100% allocated to stocks.

The Index will make any prescribed allocations to cash in accordance with the mathematical formula only at month end. In the event that it does, the Fund may experience higher portfolio turnover and incur additional transaction costs.

During any periods of significant market decline, when the Index's exposure to the market is less than 100%, the cash portion of the Index will be allocated to 30-day U.S. Treasury bills. The Fund will invest the portion of its portfolio corresponding to the cash portion of the Index in Treasury bills with a duration generally of 90 days or less or in investment companies, such as money market funds.

While the Fund generally seeks to track the returns of the Index before fees and expenses by employing a replication strategy that seeks to hold all the stocks in the Index, at times the Fund may pursue its investment objective by investing in the Index securities indirectly by investing all or a portion of its assets in another investment company advised by the Adviser, including an exchange-traded fund ("ETF"), that seeks to track the Index or the Reference Index.

Principal Risks of Investing in the Fund

The Fund's investments are subject to the following principal risks:

nEquity Risk — The value of the equity securities in which the Fund invests may decline in response to developments affecting individual companies and/or general economic conditions. A company's earnings or dividends may not increase as expected. Price changes may be temporary or last for extended periods.

nETF Structure Risks — The Fund is structured as an ETF and as a result is subject to special risks, including:

nNot Individually Redeemable —The Fund's Shares are not individually redeemable and may be redeemed by the Fund at its net asset value per share ("NAV") only in large blocks known as "Creation Units." You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit. Alternatively, you may redeem your Shares by selling them on the secondary market at prevailing market prices.

nTrading Issues —Trading in Shares on the Exchange (as defined below) may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. There is no guarantee that an active secondary market will develop for the Shares. In stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund's underlying portfolio holdings, which may lead to differences between the market price of the Shares and the underlying value of those Shares.

nMarket Price Variance Risk —The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a "bid-ask spread" charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a premium or discount to NAV.

nAuthorized Participants Concentration Risk —A limited number of financial institutions may be responsible for all or a significant portion of the creation and redemption activity for the Fund. If these firms exit the business or are unable or unwilling to process creation and/or redemption orders, Shares may trade at a premium or discount to NAV.

nIntraday Indicative Value (IIV) Risk —The Exchange intends to disseminate the approximate per share value of the Fund's published basket of securities ("Deposit Securities") every 15 seconds (the "intraday indicative value" or "IIV''). The IIV is not a "real-time" update of the NAV per share of the Fund because the IIV may not be calculated in the same manner as the NAV. For example, the calculation of the NAV may be subject to fair valuation at different prices than those used in the calculations of the IIV and, unlike the calculation of NAV, the IIV does not take into account Fund expenses. In addition, the IIV is based on the published Deposit Securities and not on the Fund's actual holdings.

nFixed Income Risk — The value of the Fund's direct or indirect investments in fixed income securities changes in response to various factors, including, for example, market-related factors (such as changes in interest rates or changes in the risk appetite of investors generally) and changes in the actual or perceived ability of the issuer (or of issuers generally) to meet its (or their) obligations.

nIndex/Defensive Positioning Risk — Because the Index's allocation to cash versus securities is determined at month-end, there is a risk that the Index, and thus the Fund, will not react to changes in market conditions that occur between reallocations. The Fund will incur transaction costs and potentially adverse tax consequences in the event the Index allocates to cash. There is no guarantee that the Index's prescribed defensive strategy, if employed, will be successful in minimizing downside market risk.

nInvestment Company Risk — An investment company (including an ETF) or similar vehicle in which the Fund invests may not achieve its investment objective. Underlying investment vehicles are subject to investment advisory and other expenses, which will be indirectly paid by the Fund. Lack of liquidity in an ETF could result in an ETF being more volatile than the underlying portfolio of securities.

nLarge Capitalization Stock Risk — The securities of large cap companies may underperform the securities of smaller cap companies or the market as a whole. The growth rate of larger, more established companies may lag those of smaller companies, especially during periods of economic expansion.

nLimited History of Operations — The Fund is a new ETF and, therefore, has a limited history of operations for investors to evaluate.

nPassive Investment Risk — The Fund is designed to track the Index and is not actively managed. The Fund will not buy or sell shares of an equity security due to current or projected performance of a security, industry or sector, unless that security is added to or removed, respectively, from the Index. The Fund does not, therefore, seek returns in excess of the Index, and does not attempt to take defensive positions or hedge against potential risks unless such defensive positions are also taken by the applicable Index.

nPortfolio Turnover Risk — Higher portfolio turnover ratios resulting from additional purchases and sales of portfolio securities will generally result in higher transaction costs and Fund expenses and may result in more significant distributions of short-term capital gains to investors, which are taxed as ordinary income.

nStock Market Risk — Overall stock market risks may affect the value of the Fund. Factors such as domestic and international economic growth and market conditions, interest rate levels and political events affect the securities markets.

nTracking Risks — The Fund's return may not match the return of the Index for a number of reasons, including: the Fund incurs operating expenses not applicable to the Index, and incurs costs in buying and selling securities; the Fund may not be fully invested at times; differences in the valuation of securities; and differences between the Fund's portfolio and the Index resulting from legal restrictions, cost or liquidity constraints.

You may lose money by investing in the Fund. There is no guarantee that the Fund will achieve its objective. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Company (FDIC) or any other government agency.

By itself, the Fund does not constitute a complete investment plan and should be considered a long-term investment for investors who can afford to weather changes in the value of their investment.

The Fund's investments are subject to the following principal risks:

nEquity Risk — The value of the equity securities in which the Fund invests may decline in response to developments affecting individual companies and/or general economic conditions. A company's earnings or dividends may not increase as expected. Price changes may be temporary or last for extended periods.

nETF Structure Risks — The Fund is structured as an ETF and as a result is subject to special risks, including:

nNot Individually Redeemable —The Fund's Shares are not individually redeemable and may be redeemed by the Fund at its net asset value per share ("NAV") only in large blocks known as "Creation Units." You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit. Alternatively, you may redeem your Shares by selling them on the secondary market at prevailing market prices.

nTrading Issues —Trading in Shares on the Exchange (as defined below) may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. There is no guarantee that an active secondary market will develop for the Shares. In stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund's underlying portfolio holdings, which may lead to differences between the market price of the Shares and the underlying value of those Shares.

nMarket Price Variance Risk —The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a "bid-ask spread" charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a premium or discount to NAV.

nAuthorized Participants Concentration Risk —A limited number of financial institutions may be responsible for all or a significant portion of the creation and redemption activity for the Fund. If these firms exit the business or are unable or unwilling to process creation and/or redemption orders, Shares may trade at a premium or discount to NAV.

nIntraday Indicative Value (IIV) Risk —The Exchange intends to disseminate the approximate per share value of the Fund's published basket of securities ("Deposit Securities") every 15 seconds (the "intraday indicative value" or "IIV''). The IIV is not a "real-time" update of the NAV per share of the Fund because the IIV may not be calculated in the same manner as the NAV. For example, the calculation of the NAV may be subject to fair valuation at different prices than those used in the calculations of the IIV and, unlike the calculation of NAV, the IIV does not take into account Fund expenses. In addition, the IIV is based on the published Deposit Securities and not on the Fund's actual holdings.

nFixed Income Risk — The value of the Fund's direct or indirect investments in fixed income securities changes in response to various factors, including, for example, market-related factors (such as changes in interest rates or changes in the risk appetite of investors generally) and changes in the actual or perceived ability of the issuer (or of issuers generally) to meet its (or their) obligations.

nIndex/Defensive Positioning Risk — Because the Index's allocation to cash versus securities is determined at month-end, there is a risk that the Index, and thus the Fund, will not react to changes in market conditions that occur between reallocations. The Fund will incur transaction costs and potentially adverse tax consequences in the event the Index allocates to cash. There is no guarantee that the Index's prescribed defensive strategy, if employed, will be successful in minimizing downside market risk.

nInvestment Company Risk — An investment company (including an ETF) or similar vehicle in which the Fund invests may not achieve its investment objective. Underlying investment vehicles are subject to investment advisory and other expenses, which will be indirectly paid by the Fund. Lack of liquidity in an ETF could result in an ETF being more volatile than the underlying portfolio of securities.

nLarge Capitalization Stock Risk — The securities of large cap companies may underperform the securities of smaller cap companies or the market as a whole. The growth rate of larger, more established companies may lag those of smaller companies, especially during periods of economic expansion.

nLimited History of Operations — The Fund is a new ETF and, therefore, has a limited history of operations for investors to evaluate.

nPassive Investment Risk — The Fund is designed to track the Index and is not actively managed. The Fund will not buy or sell shares of an equity security due to current or projected performance of a security, industry or sector, unless that security is added to or removed, respectively, from the Index. The Fund does not, therefore, seek returns in excess of the Index, and does not attempt to take defensive positions or hedge against potential risks unless such defensive positions are also taken by the applicable Index.

nPortfolio Turnover Risk — Higher portfolio turnover ratios resulting from additional purchases and sales of portfolio securities will generally result in higher transaction costs and Fund expenses and may result in more significant distributions of short-term capital gains to investors, which are taxed as ordinary income.

nStock Market Risk — Overall stock market risks may affect the value of the Fund. Factors such as domestic and international economic growth and market conditions, interest rate levels and political events affect the securities markets.

nTracking Risks — The Fund's return may not match the return of the Index for a number of reasons, including: the Fund incurs operating expenses not applicable to the Index, and incurs costs in buying and selling securities; the Fund may not be fully invested at times; differences in the valuation of securities; and differences between the Fund's portfolio and the Index resulting from legal restrictions, cost or liquidity constraints.

You may lose money by investing in the Fund. There is no guarantee that the Fund will achieve its objective. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Company (FDIC) or any other government agency.

By itself, the Fund does not constitute a complete investment plan and should be considered a long-term investment for investors who can afford to weather changes in the value of their investment.

VictoryShares US EQ Income Enhanced Volatility Wtd ETF

VictoryShares US EQ Income Enhanced Volatility Wtd ETF

Investment Objective

The Fund seeks to provide investment results that track the performance of the Nasdaq Victory US Large Cap High Dividend 100 Long/Cash Volatility Weighted Index before fees and expenses.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares ("Shares") of the Fund. Investors may incur usual or customary brokerage commissions and other charges on their purchases and sales of Shares of the Fund in the secondary market, which are not reflected in the table or the example below.

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees	VictoryShares US EQ Income Enhanced Volatility Wtd ETF VictoryShares US EQ Income Enhanced Volatility Wtd ETF USD ($)
Shareholder Fees (fees paid directly from your investment)	none

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	VictoryShares US EQ Income Enhanced Volatility Wtd ETF VictoryShares US EQ Income Enhanced Volatility Wtd ETF
Management Fees	0.30%
Other Expenses	0.11%
Total Annual Fund Operating Expenses	0.41%
Fee Waivers/Expense Reimbursements	(0.06%)	[1]
Total Annual Fund Operating Expenses After Fee Waivers and Expense Reimbursements	0.35%	[1]

Example:

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The amounts shown reflect the fee waiver/expense reimbursement in place through the expiration date. Although your actual costs may be higher or lower, based upon these assumptions your costs would be:

Expense Example	1 Year	3 Years	5 Years	10 Years
VictoryShares US EQ Income Enhanced Volatility Wtd ETF | VictoryShares US EQ Income Enhanced Volatility Wtd ETF | USD ($)	36	126	224	512

Portfolio Turnover:

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover will generally indicate higher transaction costs resulting in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover was 52% of the average value of its portfolio.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by investing, under normal market conditions, at least 80% of its assets directly or indirectly in the securities included in the Nasdaq Victory US Large Cap 100 High Dividend Long/Cash Volatility Weighted Index (the "Index"), an unmanaged, volatility weighted index maintained exclusively by Nasdaq Inc. (the "Index Provider"). The Index Provider is not affiliated with the Fund or the Adviser.

The Index combines fundamental criteria with individual security risk control achieved through volatility weighting of individual securities. In accordance with a rules-based mathematical formula, the Index tactically reduces its exposure to the equity markets during periods of significant market decline and reallocates to stocks when market prices have further declined or rebounded. The term "Enhanced" in the Fund's name refers to a feature of the Index that is designed to enhance risk-adjusted returns while attempting to minimize downside market risk through defensive positioning, as described below.

The Index follows a rules-based methodology to construct its constituent securities:

•  The Index universe begins with the stocks included in the Nasdaq Victory US Large Cap 500 Volatility Weighted Index, a volatility weighted index comprised of the 500 largest U.S. companies by market capitalization with positive earnings in each of the four most recent quarters.

•  The Index identifies the 100 highest dividend yielding stocks in the Nasdaq Victory US Large Cap 500 Volatility Weighted Index.

•  The 100 stocks are weighted based on their daily standard deviation (volatility) of daily price changes over the last 180 trading days. Stocks with lower volatility receive a higher weighting and stocks with higher volatility receive a lower weighting.

The Index is reconstituted every March and September (based on information as of the prior month-end) and is adjusted to limit exposure to any particular sector to 25%. The Index may include less than 100 stocks depending on the number of companies meeting the Index's criteria. As of September 30, 2018, the Index had a market capitalization range from $4 billion to $360 billion.

The Index follows a mathematical index construction process designed to limit risk during periods of significant (non-normal) market decline by reducing its exposure to the equity market. Market decline is measured by reference to the Nasdaq Victory US Large Cap 100 High Dividend Volatility Weighted Index ("Reference Index"), which is composed of the same securities as in the Index but without any allocation to cash.

During a period of significant market decline, defined as a decline of 8% or more from the Reference Index's all-time daily high closing value compared to its most recent month-end closing value, the Index's exposure to the market may be as low as 25% depending on the magnitude and duration of such decline.

If the month-end value of the Reference Index declines 8% or more from its all-time closing high, the Index will reallocate 75% of the stocks included in the Index to cash or cash equivalents.

The Index will reallocate to stocks as follows:

•  The Index will return to being 100% allocated to stocks if the month-end closing value of the stocks in the Reference Index returns to a level that is less than an 8% decline from its all-time daily high closing value.

•  If the Reference Index declines by 16% (or more) from its all-time daily high closing value as measured at month-end, 25% of the Index will reallocate to the stocks of the Reference Index at their current securities weightings.

•  If the Reference Index declines by 24% (or more) from its all-time daily high closing value as measured at month-end, another 25% of the Index will reallocate to the stocks of the Reference Index at their current securities weightings.

•  If the Reference Index declines by 32% (or more) from its all-time daily high closing value as measured at month-end, the remaining 25% of the Index will reallocated to the stocks of the Reference Index at their current securities weighting and the Index will then be 100% allocated to stocks.

The Index will make any prescribed allocations to cash in accordance with the mathematical formula only at month end. In the event that it does, the Fund may experience higher portfolio turnover and incur additional transaction costs.

During any periods of significant market decline, when the Index's exposure to the market is less than 100%, the cash portion of the Index will be allocated to 30-day U.S. Treasury bills. The Fund will invest the portion of its portfolio corresponding to the cash portion of the Index in Treasury bills with a duration generally of 90 days or less or in investment companies, such as money market funds.

While the Fund generally seeks to track the returns of the Index before fees and expenses by employing a replication strategy that seeks to hold all the stocks in the Index, at times the Fund may pursue its investment objective by investing in the Index securities indirectly by investing all or a portion of its assets in another investment company advised by the Adviser, including an exchange-traded fund ("ETF"), that seeks to track the Index or the Reference Index.

Principal Risks of Investing in the Fund

The following summarizes the principal investment risks of the Fund. Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective and an investment in the Fund is not by itself a complete or balanced investment program.

nDividend Income Strategy Risk — The Fund's high dividend strategy may not be successful. Dividend paying stocks may fall out of favor relative to the overall market.

nEquity Risk — The value of the equity securities in which the Fund invests may decline in response to developments affecting individual companies and/or general economic conditions. A company's earnings or dividends may not increase as expected. Price changes may be temporary or last for extended periods.

nETF Structure Risks — The Fund is structured as an ETF and as a result is subject to special risks, including:

nNot Individually Redeemable —The Fund's Shares are not individually redeemable and may be redeemed by the Fund at its net asset value per share ("NAV") only in large blocks known as "Creation Units." You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit. Alternatively, you may redeem your Shares by selling them on the secondary market at prevailing market prices.

nTrading Issues —Trading in Shares on the Exchange (as defined below) may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. There is no guarantee that an active secondary market will develop for the Shares. In stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund's underlying portfolio holdings, which may lead to differences between the market price of the Shares and the underlying value of those Shares.

nMarket Price Variance Risk —The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a "bid-ask spread" charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a premium or discount to NAV.

nAuthorized Participants Concentration Risk —A limited number of financial institutions may be responsible for all or a significant portion of the creation and redemption activity for the Fund. If these firms exit the business or are unable or unwilling to process creation and/or redemption orders, Shares may trade at a premium or discount to NAV.

nIntraday Indicative Value (IIV) Risk —The Exchange intends to disseminate the approximate per share value of the Fund's published basket of securities ("Deposit Securities") every 15 seconds (the "intraday indicative value" or "IIV''). The IIV is not a "real-time" update of the NAV per share of the Fund because the IIV may not be calculated in the same manner as the NAV. For example, the calculation of the NAV may be subject to fair valuation at different prices than those used in the calculations of the IIV and, unlike the calculation of NAV, the IIV does not take into account Fund expenses. In addition, the IIV is based on the published Deposit Securities and not on the Fund's actual holdings.

nFixed Income Risk — The value of the Fund's direct or indirect investments in fixed income securities changes in response to various factors, including, for example, market-related factors (such as changes in interest rates or changes in the risk appetite of investors generally) and changes in the actual or perceived ability of the issuer (or of issuers generally) to meet its (or their) obligations.

The Fund will incur transaction costs and potentially adverse tax consequences in the event the Index allocates to cash. There is no guarantee that the Index's prescribed defensive strategy, if employed, will be successful in minimizing downside market risk.

nInvestment Company Risk — An investment company (including an ETF) or similar vehicle in which the Fund invests may not achieve its investment objective. Underlying investment vehicles are subject to investment advisory and other expenses, which will be indirectly paid by the Fund. Lack of liquidity in an ETF could result in an ETF being more volatile than the underlying portfolio of securities.

nLarge Capitalization Stock Risk — The securities of large cap companies may underperform the securities of smaller cap companies or the market as a whole. Larger, more established companies may not respond as quickly to competitive challenges (such as changes in technology and consumer tastes) and their growth rate may lag those of smaller companies, especially during periods of economic expansion.

nLimited History of Operations — The Fund is a new ETF and, therefore, has a limited history of operations for investors to evaluate.

nPassive Investment Risk — The Fund is designed to track the Index and is not actively managed. The Fund does not, therefore, seek returns in excess of the Index, and does not attempt to take defensive positions or hedge against potential risks unless such defensive positions are also taken by the applicable Index. The Adviser will not buy or sell shares of an equity security due to current or projected performance of a security, industry or sector, unless that security is added to or removed, respectively, from the Index.

nPortfolio Turnover Risk — Higher portfolio turnover ratios resulting from additional purchases and sales of portfolio securities will generally result in higher transaction costs and Fund expenses and may result in more significant distributions of short-term capital gains to investors, which are taxed as ordinary income.

n  Stock Market Risk — Overall stock market risks may affect the value of the Fund. Factors such as domestic and international economic growth and market conditions, interest rate levels and political events affect the securities markets.

n  Tracking Risk — The Fund's return may not match the return of the Index for a number of reasons, including: the Fund incurs operating expenses not applicable to the Index and incurs costs in buying and selling securities; the Fund may not be fully invested at times; differences in the valuation of securities; and differences between the Fund's portfolio and the Index resulting from legal restrictions, cost or liquidity constraints.

You may lose money by investing in the Fund. There is no guarantee that the Fund will achieve its objective. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Company (FDIC) or any other government agency.

The Fund seeks to achieve its investment objective by investing, under normal market conditions, at least 80% of its assets directly or indirectly in the securities included in the Nasdaq Victory US Large Cap 100 High Dividend Long/Cash Volatility Weighted Index (the "Index"), an unmanaged, volatility weighted index maintained exclusively by Nasdaq Inc. (the "Index Provider"). The Index Provider is not affiliated with the Fund or the Adviser.

The Index combines fundamental criteria with individual security risk control achieved through volatility weighting of individual securities. In accordance with a rules-based mathematical formula, the Index tactically reduces its exposure to the equity markets during periods of significant market decline and reallocates to stocks when market prices have further declined or rebounded. The term "Enhanced" in the Fund's name refers to a feature of the Index that is designed to enhance risk-adjusted returns while attempting to minimize downside market risk through defensive positioning, as described below.

The Index follows a rules-based methodology to construct its constituent securities:

•  The Index universe begins with the stocks included in the Nasdaq Victory US Large Cap 500 Volatility Weighted Index, a volatility weighted index comprised of the 500 largest U.S. companies by market capitalization with positive earnings in each of the four most recent quarters.

•  The Index identifies the 100 highest dividend yielding stocks in the Nasdaq Victory US Large Cap 500 Volatility Weighted Index.

•  The 100 stocks are weighted based on their daily standard deviation (volatility) of daily price changes over the last 180 trading days. Stocks with lower volatility receive a higher weighting and stocks with higher volatility receive a lower weighting.

The Index is reconstituted every March and September (based on information as of the prior month-end) and is adjusted to limit exposure to any particular sector to 25%. The Index may include less than 100 stocks depending on the number of companies meeting the Index's criteria. As of September 30, 2018, the Index had a market capitalization range from $4 billion to $360 billion.

The Index follows a mathematical index construction process designed to limit risk during periods of significant (non-normal) market decline by reducing its exposure to the equity market. Market decline is measured by reference to the Nasdaq Victory US Large Cap 100 High Dividend Volatility Weighted Index ("Reference Index"), which is composed of the same securities as in the Index but without any allocation to cash.

During a period of significant market decline, defined as a decline of 8% or more from the Reference Index's all-time daily high closing value compared to its most recent month-end closing value, the Index's exposure to the market may be as low as 25% depending on the magnitude and duration of such decline.

If the month-end value of the Reference Index declines 8% or more from its all-time closing high, the Index will reallocate 75% of the stocks included in the Index to cash or cash equivalents.

The Index will reallocate to stocks as follows:

•  The Index will return to being 100% allocated to stocks if the month-end closing value of the stocks in the Reference Index returns to a level that is less than an 8% decline from its all-time daily high closing value.

•  If the Reference Index declines by 16% (or more) from its all-time daily high closing value as measured at month-end, 25% of the Index will reallocate to the stocks of the Reference Index at their current securities weightings.

•  If the Reference Index declines by 24% (or more) from its all-time daily high closing value as measured at month-end, another 25% of the Index will reallocate to the stocks of the Reference Index at their current securities weightings.

•  If the Reference Index declines by 32% (or more) from its all-time daily high closing value as measured at month-end, the remaining 25% of the Index will reallocated to the stocks of the Reference Index at their current securities weighting and the Index will then be 100% allocated to stocks.

The Index will make any prescribed allocations to cash in accordance with the mathematical formula only at month end. In the event that it does, the Fund may experience higher portfolio turnover and incur additional transaction costs.

During any periods of significant market decline, when the Index's exposure to the market is less than 100%, the cash portion of the Index will be allocated to 30-day U.S. Treasury bills. The Fund will invest the portion of its portfolio corresponding to the cash portion of the Index in Treasury bills with a duration generally of 90 days or less or in investment companies, such as money market funds.

While the Fund generally seeks to track the returns of the Index before fees and expenses by employing a replication strategy that seeks to hold all the stocks in the Index, at times the Fund may pursue its investment objective by investing in the Index securities indirectly by investing all or a portion of its assets in another investment company advised by the Adviser, including an exchange-traded fund ("ETF"), that seeks to track the Index or the Reference Index.

Principal Risks of Investing in the Fund

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The following summarizes the principal investment risks of the Fund. Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective and an investment in the Fund is not by itself a complete or balanced investment program.

nDividend Income Strategy Risk — The Fund's high dividend strategy may not be successful. Dividend paying stocks may fall out of favor relative to the overall market.

nEquity Risk — The value of the equity securities in which the Fund invests may decline in response to developments affecting individual companies and/or general economic conditions. A company's earnings or dividends may not increase as expected. Price changes may be temporary or last for extended periods.

nETF Structure Risks — The Fund is structured as an ETF and as a result is subject to special risks, including:

nNot Individually Redeemable —The Fund's Shares are not individually redeemable and may be redeemed by the Fund at its net asset value per share ("NAV") only in large blocks known as "Creation Units." You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit. Alternatively, you may redeem your Shares by selling them on the secondary market at prevailing market prices.

nTrading Issues —Trading in Shares on the Exchange (as defined below) may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. There is no guarantee that an active secondary market will develop for the Shares. In stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund's underlying portfolio holdings, which may lead to differences between the market price of the Shares and the underlying value of those Shares.

nMarket Price Variance Risk —The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a "bid-ask spread" charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a premium or discount to NAV.

nAuthorized Participants Concentration Risk —A limited number of financial institutions may be responsible for all or a significant portion of the creation and redemption activity for the Fund. If these firms exit the business or are unable or unwilling to process creation and/or redemption orders, Shares may trade at a premium or discount to NAV.

nIntraday Indicative Value (IIV) Risk —The Exchange intends to disseminate the approximate per share value of the Fund's published basket of securities ("Deposit Securities") every 15 seconds (the "intraday indicative value" or "IIV''). The IIV is not a "real-time" update of the NAV per share of the Fund because the IIV may not be calculated in the same manner as the NAV. For example, the calculation of the NAV may be subject to fair valuation at different prices than those used in the calculations of the IIV and, unlike the calculation of NAV, the IIV does not take into account Fund expenses. In addition, the IIV is based on the published Deposit Securities and not on the Fund's actual holdings.

nFixed Income Risk — The value of the Fund's direct or indirect investments in fixed income securities changes in response to various factors, including, for example, market-related factors (such as changes in interest rates or changes in the risk appetite of investors generally) and changes in the actual or perceived ability of the issuer (or of issuers generally) to meet its (or their) obligations.

nIndex/Defensive Positioning Risk — Because the Index's allocation to cash versus securities is determined at month-end, there is a risk that the Index, and thus the Fund, will not react to changes in market conditions that occur between reallocations. The Fund will incur transaction costs and potentially adverse tax consequences in the event the Index allocates to cash. There is no guarantee that the Index's prescribed defensive strategy, if employed, will be successful in minimizing downside market risk.

nInvestment Company Risk — An investment company (including an ETF) or similar vehicle in which the Fund invests may not achieve its investment objective. Underlying investment vehicles are subject to investment advisory and other expenses, which will be indirectly paid by the Fund. Lack of liquidity in an ETF could result in an ETF being more volatile than the underlying portfolio of securities.

nLarge Capitalization Stock Risk — The securities of large cap companies may underperform the securities of smaller cap companies or the market as a whole. Larger, more established companies may not respond as quickly to competitive challenges (such as changes in technology and consumer tastes) and their growth rate may lag those of smaller companies, especially during periods of economic expansion.

nLimited History of Operations — The Fund is a new ETF and, therefore, has a limited history of operations for investors to evaluate.

nPassive Investment Risk — The Fund is designed to track the Index and is not actively managed. The Fund does not, therefore, seek returns in excess of the Index, and does not attempt to take defensive positions or hedge against potential risks unless such defensive positions are also taken by the applicable Index. The Adviser will not buy or sell shares of an equity security due to current or projected performance of a security, industry or sector, unless that security is added to or removed, respectively, from the Index.

nPortfolio Turnover Risk — Higher portfolio turnover ratios resulting from additional purchases and sales of portfolio securities will generally result in higher transaction costs and Fund expenses and may result in more significant distributions of short-term capital gains to investors, which are taxed as ordinary income.

n  Stock Market Risk — Overall stock market risks may affect the value of the Fund. Factors such as domestic and international economic growth and market conditions, interest rate levels and political events affect the securities markets.

n  Tracking Risk — The Fund's return may not match the return of the Index for a number of reasons, including: the Fund incurs operating expenses not applicable to the Index and incurs costs in buying and selling securities; the Fund may not be fully invested at times; differences in the valuation of securities; and differences between the Fund's portfolio and the Index resulting from legal restrictions, cost or liquidity constraints.

You may lose money by investing in the Fund. There is no guarantee that the Fund will achieve its objective. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Company (FDIC) or any other government agency.

By itself, the Fund does not constitute a complete investment plan and should be considered a long-term investment for investors who can afford to weather changes in the value of their investment.

VictoryShares US Discovery Enhanced Volatility Wtd ETF

VictoryShares US Discovery Enhanced Volatility Wtd ETF

Investment Objective

The Fund seeks to provide investment results that track the performance of the Nasdaq Victory US Small Cap 500 Long/Cash Volatility Weighted Index before fees and expenses.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares ("Shares") of the Fund. Investors may incur usual or customary brokerage commissions and other charges on their purchases and sales of Shares of the Fund in the secondary market, which are not reflected in the table or the example below.

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees	VictoryShares US Discovery Enhanced Volatility Wtd ETF VictoryShares US Discovery Enhanced Volatility Wtd ETF USD ($)
Shareholder Fees (fees paid directly from your investment)	none

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	VictoryShares US Discovery Enhanced Volatility Wtd ETF VictoryShares US Discovery Enhanced Volatility Wtd ETF
Management Fees	0.30%
Other Expenses	0.13%
Total Annual Fund Operating Expenses	0.43%
Fee Waivers/Expense Reimbursements	(0.08%)	[1]
Total Annual Fund Operating Expenses After Fee Waivers and Expense Reimbursements	0.35%	[1]

Example:

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The amounts shown reflect the fee waiver/expense reimbursement in place through the expiration date. Although your actual costs may be higher or lower, based upon these assumptions your costs would be:

Expense Example	1 Year	3 Years	5 Years	10 Years
VictoryShares US Discovery Enhanced Volatility Wtd ETF | VictoryShares US Discovery Enhanced Volatility Wtd ETF | USD ($)	36	130	233	534

Portfolio Turnover:

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover will generally indicate higher transaction costs resulting in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover was 47% of the average value of its portfolio.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by investing, under normal market conditions, at least 80% of its assets directly or indirectly in the securities included in the Nasdaq Victory US Small Cap 500 Long/Cash Volatility Weighted Index (the "Index"), an unmanaged, volatility weighted index maintained exclusively by Nasdaq Inc. (the "Index Provider"). The Index Provider is not affiliated with the Fund or the Adviser.

The Index combines fundamental criteria with individual security risk control achieved through volatility weighting of individual securities. In accordance with a rules-based mathematical formula, the Index tactically reduces its exposure to the equity markets during periods of significant market decline and reallocates to stocks when market prices have further declined or rebounded. The term "Enhanced" in the Fund's name refers to a feature of the Index that is designed to enhance risk-adjusted returns while attempting to minimize downside market risk through defensive positioning, as described below.

The Index follows a rules-based methodology to construct its constituent securities:

•  The Index universe begins with all publicly traded U.S. stocks and then screens for all companies with positive earnings in each of the four most recent quarters.

•  The Index identifies the 500 largest U.S companies with market capitalizations of less than $3 billion measured at the time the Index's constituent securities are determined.

•  The 500 stocks are weighted based on their daily standard deviation (volatility) of daily price changes over the last 180 trading days. Stocks with lower volatility receive a higher weighting and stocks with higher volatility receive a lower weighting.

The Index is reconstituted every March and September (based on information as of the prior month-end) and is adjusted to limit exposure to any particular sector to 25%. The Index may include more than or fewer than 500 stocks depending on the number of companies meeting the Index's criteria. As of September 30, 2018, the Index had a market capitalization range from $166.6 million to $3.3 billion.

The Index follows a mathematical index construction process designed to limit risk during periods of significant (non-normal) market decline by reducing its exposure to the equity market. Market decline is measured by reference to the Nasdaq Victory US Small Cap 500 Volatility Weighted Index ("Reference Index"), which is composed of the same securities as in the Index but without any allocation to cash.

During a period of significant market decline, defined as a decline of 11% or more from the Reference Index's all-time daily high closing value compared to its most recent month-end closing value, the Index's exposure to the market may be as low as 25% depending on the magnitude and duration of such decline.

If the month-end value of the Reference Index declines 11% or more from its all-time closing high, the Index will reallocate 75% of the stocks included in the Index to cash or cash equivalents.

The Index will reallocate to stocks as follows:

•  The Index will return to being 100% allocated to stocks if the month-end closing value of the stocks in the Reference Index returns to a level that is less than a 11% decline from its all-time daily high closing value.

•  If the Reference Index declines by 22% (or more) from its all-time daily high closing value as measured at month-end, 25% of the Index will reallocate to the stocks of the Reference Index at their current securities weightings.

•  If the Reference Index declines by 33% (or more) from its all-time daily high closing value as measured at month-end, another 25% of the Index will reallocate to the stocks of the Reference Index at their current securities weightings.

•  If the Reference Index declines by 44% (or more) from its all-time daily high closing value as measured at month-end, the remaining 25% of the Index will reallocated to the stocks of the Reference Index at their current securities weighting and the Index will then be 100% allocated to stocks.

The Index will make any prescribed allocations to cash in accordance with the mathematical formula only at month end. In the event that it does, the Fund may experience higher portfolio turnover and incur additional transaction costs.

During any periods of significant market decline, when the Index's exposure to the market is less than 100%, the cash portion of the Index will be allocated to 30-day U.S. Treasury bills. The Fund will invest the portion of its portfolio corresponding to the cash portion of the Index in Treasury bills with a duration generally of 90 days or less or in investment companies, such as money market funds.

While the Fund generally seeks to track the returns of the Index before fees and expenses by employing a replication strategy that seeks to hold all the stocks in the Index, at times the Fund may pursue its investment objective by investing in the Index securities indirectly by investing all or a portion of its assets in another investment company advised by the Adviser, including an exchange-traded fund ("ETF"), that seeks to track the Index or the Reference Index.

Principal Risks of Investing in the Fund

The Fund's investments are subject to the following principal risks:

nEquity Risk — The value of the equity securities in which the Fund invests may decline in response to developments affecting individual companies and/or general economic conditions. A company's earnings or dividends may not increase as expected. Price changes may be temporary or last for extended periods.

nETF Structure Risks — The Fund is structured as an ETF and as a result is subject to special risks, including:

nNot Individually Redeemable —The Fund's Shares are not individually redeemable and may be redeemed by the Fund at its net asset value per share ("NAV") only in large blocks known as "Creation Units." You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit. Alternatively, you may redeem your Shares by selling them on the secondary market at prevailing market prices.

nTrading Issues —Trading in Shares on the Exchange (as defined below) may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. There is no guarantee that an active secondary market will develop for the Shares. In stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund's underlying portfolio holdings, which may lead to differences between the market price of the Shares and the underlying value of those Shares.

n  Market Price Variance Risk —The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a "bid-ask spread" charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a premium or discount to NAV.

n  Authorized Participants Concentration Risk —A limited number of financial institutions may be responsible for all or a significant portion of the creation and redemption activity for the Fund. If these firms exit the business or are unable or unwilling to process creation and/or redemption orders, Shares may trade at a premium or discount to NAV.

n  Intraday Indicative Value (IIV) Risk —The Exchange intends to disseminate the approximate per share value of the Fund's published basket of securities ("Deposit Securities") every 15 seconds (the "intraday indicative value" or "IIV''). The IIV is not a "real-time" update of the NAV per share of the Fund because the IIV may not be calculated in the same manner as the NAV. For example, the calculation of the NAV may be subject to fair valuation at different prices than those used in the calculations of the IIV and, unlike the calculation of NAV, the IIV does not take into account Fund expenses. In addition, the IIV is based on the published Deposit Securities and not on the Fund's actual holdings.

n  Fixed Income Risk — The value of the Fund's direct or indirect investments in fixed income securities changes in response to various factors, including, for example, market-related factors (such as changes in interest rates or changes in the risk appetite of investors generally) and changes in the actual or perceived ability of the issuer (or of issuers generally) to meet its (or their) obligations.

n  Index/Defensive Positioning Risk — Because the Index's allocation to cash versus securities is determined at month-end, there is a risk that the Index, and thus the Fund, will not react to changes in market conditions that occur between reallocations. The Fund will incur transaction costs and potentially adverse tax consequences in the event the Index allocates to cash. There is no guarantee that the Index's prescribed liquidation and reinvestment strategy, if employed, will be successful in minimizing downside market risk.

n  Investment Company Risk — An investment company (including an ETF) or similar vehicle in which the Fund invests may not achieve its investment objective. Underlying investment vehicles are subject to investment advisory and other expenses, which will be indirectly paid by the Fund. Lack of liquidity in an ETF could result in an ETF being more volatile than the underlying portfolio of securities.

nLimited History of Operations — The Fund is a new ETF and, therefore, has a limited history of operations for investors to evaluate.

nLiquidity Risk — In certain circumstances, such as the disruption of the orderly markets for the securities in which the Fund invests, the Fund might not be able to dispose of certain holdings quickly or at prices that represent true market value in the judgment of the Adviser. Markets for the securities in which the Fund invests may be disrupted by a number of events, including but not limited to economic crises, natural disasters, new legislation, or regulatory changes, and may prevent the Fund from limiting losses, realizing gains or achieving a high correlation with the Index.

n  Passive Investment Risk — The Fund is designed to track the Index and is not actively managed. The Fund will not buy or sell shares of an equity security due to current or projected performance of a security, industry or sector, unless that security is added to or removed, respectively, from the Index. The Fund does not, therefore, seek returns in excess of the Index, and does not attempt to take defensive positions or hedge against potential risks unless such defensive positions are also taken by the applicable Index.

n  Portfolio Turnover Risk — Higher portfolio turnover ratios resulting from additional purchases and sales of portfolio securities will generally result in higher transaction costs and Fund expenses and may result in more significant distributions of short-term capital gains to investors, which are taxed as ordinary income.

n  Small Company Risk — Small-sized companies may be subject to a number of risks not associated with larger, more established companies, potentially making their stock prices more volatile and increasing the risk of loss. Smaller companies may have limited markets, product lines, or financial resources and lack management experience and may experience higher failure rates than larger companies.

nStock Market Risk — Overall stock market risks may affect the value of the Fund. Factors such as domestic and international economic growth and market conditions, interest rate levels and political events affect the securities markets.

nTracking Risk — The Fund's return may not match the return of the Index for a number of reasons, including: the Fund incurs operating expenses not applicable to the Index and incurs costs in buying and selling securities; the Fund may not be fully invested at times; differences in the valuation of securities; and differences between the Fund's portfolio and the Index resulting from legal restrictions, cost or liquidity constraints.

You may lose money by investing in the Fund. There is no guarantee that the Fund will achieve its objective. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Company (FDIC) or any other government agency.

By itself, the Fund does not constitute a complete investment plan and should be considered a long-term investment for investors who can afford to weather changes in the value of their investment.

Strategy [Heading]

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its investment objective by investing, under normal market conditions, at least 80% of its assets directly or indirectly in the securities included in the Nasdaq Victory US Small Cap 500 Long/Cash Volatility Weighted Index (the "Index"), an unmanaged, volatility weighted index maintained exclusively by Nasdaq Inc. (the "Index Provider"). The Index Provider is not affiliated with the Fund or the Adviser.

The Index combines fundamental criteria with individual security risk control achieved through volatility weighting of individual securities. In accordance with a rules-based mathematical formula, the Index tactically reduces its exposure to the equity markets during periods of significant market decline and reallocates to stocks when market prices have further declined or rebounded. The term "Enhanced" in the Fund's name refers to a feature of the Index that is designed to enhance risk-adjusted returns while attempting to minimize downside market risk through defensive positioning, as described below.

The Index follows a rules-based methodology to construct its constituent securities:

•  The Index universe begins with all publicly traded U.S. stocks and then screens for all companies with positive earnings in each of the four most recent quarters.

•  The Index identifies the 500 largest U.S companies with market capitalizations of less than $3 billion measured at the time the Index's constituent securities are determined.

•  The 500 stocks are weighted based on their daily standard deviation (volatility) of daily price changes over the last 180 trading days. Stocks with lower volatility receive a higher weighting and stocks with higher volatility receive a lower weighting.

The Index is reconstituted every March and September (based on information as of the prior month-end) and is adjusted to limit exposure to any particular sector to 25%. The Index may include more than or fewer than 500 stocks depending on the number of companies meeting the Index's criteria. As of September 30, 2018, the Index had a market capitalization range from $166.6 million to $3.3 billion.

The Index follows a mathematical index construction process designed to limit risk during periods of significant (non-normal) market decline by reducing its exposure to the equity market. Market decline is measured by reference to the Nasdaq Victory US Small Cap 500 Volatility Weighted Index ("Reference Index"), which is composed of the same securities as in the Index but without any allocation to cash.

During a period of significant market decline, defined as a decline of 11% or more from the Reference Index's all-time daily high closing value compared to its most recent month-end closing value, the Index's exposure to the market may be as low as 25% depending on the magnitude and duration of such decline.

If the month-end value of the Reference Index declines 11% or more from its all-time closing high, the Index will reallocate 75% of the stocks included in the Index to cash or cash equivalents.

The Index will reallocate to stocks as follows:

•  The Index will return to being 100% allocated to stocks if the month-end closing value of the stocks in the Reference Index returns to a level that is less than a 11% decline from its all-time daily high closing value.

•  If the Reference Index declines by 22% (or more) from its all-time daily high closing value as measured at month-end, 25% of the Index will reallocate to the stocks of the Reference Index at their current securities weightings.

•  If the Reference Index declines by 33% (or more) from its all-time daily high closing value as measured at month-end, another 25% of the Index will reallocate to the stocks of the Reference Index at their current securities weightings.

•  If the Reference Index declines by 44% (or more) from its all-time daily high closing value as measured at month-end, the remaining 25% of the Index will reallocated to the stocks of the Reference Index at their current securities weighting and the Index will then be 100% allocated to stocks.

The Index will make any prescribed allocations to cash in accordance with the mathematical formula only at month end. In the event that it does, the Fund may experience higher portfolio turnover and incur additional transaction costs.

During any periods of significant market decline, when the Index's exposure to the market is less than 100%, the cash portion of the Index will be allocated to 30-day U.S. Treasury bills. The Fund will invest the portion of its portfolio corresponding to the cash portion of the Index in Treasury bills with a duration generally of 90 days or less or in investment companies, such as money market funds.

While the Fund generally seeks to track the returns of the Index before fees and expenses by employing a replication strategy that seeks to hold all the stocks in the Index, at times the Fund may pursue its investment objective by investing in the Index securities indirectly by investing all or a portion of its assets in another investment company advised by the Adviser, including an exchange-traded fund ("ETF"), that seeks to track the Index or the Reference Index.

Risk [Heading]

rr_RiskHeading

Principal Risks of Investing in the Fund

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund's investments are subject to the following principal risks:

nEquity Risk — The value of the equity securities in which the Fund invests may decline in response to developments affecting individual companies and/or general economic conditions. A company's earnings or dividends may not increase as expected. Price changes may be temporary or last for extended periods.

nETF Structure Risks — The Fund is structured as an ETF and as a result is subject to special risks, including:

nNot Individually Redeemable —The Fund's Shares are not individually redeemable and may be redeemed by the Fund at its net asset value per share ("NAV") only in large blocks known as "Creation Units." You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit. Alternatively, you may redeem your Shares by selling them on the secondary market at prevailing market prices.

nTrading Issues —Trading in Shares on the Exchange (as defined below) may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. There is no guarantee that an active secondary market will develop for the Shares. In stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund's underlying portfolio holdings, which may lead to differences between the market price of the Shares and the underlying value of those Shares.

n  Market Price Variance Risk —The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a "bid-ask spread" charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a premium or discount to NAV.

n  Authorized Participants Concentration Risk —A limited number of financial institutions may be responsible for all or a significant portion of the creation and redemption activity for the Fund. If these firms exit the business or are unable or unwilling to process creation and/or redemption orders, Shares may trade at a premium or discount to NAV.

n  Intraday Indicative Value (IIV) Risk —The Exchange intends to disseminate the approximate per share value of the Fund's published basket of securities ("Deposit Securities") every 15 seconds (the "intraday indicative value" or "IIV''). The IIV is not a "real-time" update of the NAV per share of the Fund because the IIV may not be calculated in the same manner as the NAV. For example, the calculation of the NAV may be subject to fair valuation at different prices than those used in the calculations of the IIV and, unlike the calculation of NAV, the IIV does not take into account Fund expenses. In addition, the IIV is based on the published Deposit Securities and not on the Fund's actual holdings.

n  Fixed Income Risk — The value of the Fund's direct or indirect investments in fixed income securities changes in response to various factors, including, for example, market-related factors (such as changes in interest rates or changes in the risk appetite of investors generally) and changes in the actual or perceived ability of the issuer (or of issuers generally) to meet its (or their) obligations.

n  Index/Defensive Positioning Risk — Because the Index's allocation to cash versus securities is determined at month-end, there is a risk that the Index, and thus the Fund, will not react to changes in market conditions that occur between reallocations. The Fund will incur transaction costs and potentially adverse tax consequences in the event the Index allocates to cash. There is no guarantee that the Index's prescribed liquidation and reinvestment strategy, if employed, will be successful in minimizing downside market risk.

n  Investment Company Risk — An investment company (including an ETF) or similar vehicle in which the Fund invests may not achieve its investment objective. Underlying investment vehicles are subject to investment advisory and other expenses, which will be indirectly paid by the Fund. Lack of liquidity in an ETF could result in an ETF being more volatile than the underlying portfolio of securities.

nLimited History of Operations — The Fund is a new ETF and, therefore, has a limited history of operations for investors to evaluate.

nLiquidity Risk — In certain circumstances, such as the disruption of the orderly markets for the securities in which the Fund invests, the Fund might not be able to dispose of certain holdings quickly or at prices that represent true market value in the judgment of the Adviser. Markets for the securities in which the Fund invests may be disrupted by a number of events, including but not limited to economic crises, natural disasters, new legislation, or regulatory changes, and may prevent the Fund from limiting losses, realizing gains or achieving a high correlation with the Index.

n  Passive Investment Risk — The Fund is designed to track the Index and is not actively managed. The Fund will not buy or sell shares of an equity security due to current or projected performance of a security, industry or sector, unless that security is added to or removed, respectively, from the Index. The Fund does not, therefore, seek returns in excess of the Index, and does not attempt to take defensive positions or hedge against potential risks unless such defensive positions are also taken by the applicable Index.

n  Portfolio Turnover Risk — Higher portfolio turnover ratios resulting from additional purchases and sales of portfolio securities will generally result in higher transaction costs and Fund expenses and may result in more significant distributions of short-term capital gains to investors, which are taxed as ordinary income.

n  Small Company Risk — Small-sized companies may be subject to a number of risks not associated with larger, more established companies, potentially making their stock prices more volatile and increasing the risk of loss. Smaller companies may have limited markets, product lines, or financial resources and lack management experience and may experience higher failure rates than larger companies.

nStock Market Risk — Overall stock market risks may affect the value of the Fund. Factors such as domestic and international economic growth and market conditions, interest rate levels and political events affect the securities markets.

nTracking Risk — The Fund's return may not match the return of the Index for a number of reasons, including: the Fund incurs operating expenses not applicable to the Index and incurs costs in buying and selling securities; the Fund may not be fully invested at times; differences in the valuation of securities; and differences between the Fund's portfolio and the Index resulting from legal restrictions, cost or liquidity constraints.

You may lose money by investing in the Fund. There is no guarantee that the Fund will achieve its objective. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Company (FDIC) or any other government agency.

By itself, the Fund does not constitute a complete investment plan and should be considered a long-term investment for investors who can afford to weather changes in the value of their investment.

Investment Objective

The Fund seeks to provide investment results that track the performance of the Nasdaq Victory International 500 Long/Cash Volatility Weighted Index before fees and expenses.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares ("Shares") of the Fund. Investors may incur usual or customary brokerage commissions and other charges on their purchases and sales of Shares of the Fund in the secondary market, which are not reflected in the table or the example below.

Total Annual Fund Operating Expenses After Fee Waivers and Expense Reimbursements	0.45%	[1]

Example:

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The amounts shown reflect the fee waiver/expense reimbursement in place through the expiration date. Although your actual costs may be higher or lower, based upon these assumptions your costs would be:

Expense Example	1 Year	3 Years	5 Years	10 Years
VictoryShares Developed Enhanced Volatility Wtd ETF | VictoryShares Developed Enhanced Volatility Wtd ETF | USD ($)	46	173	311	713

Portfolio Turnover:

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover will generally indicate higher transaction costs resulting in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover was 38% of the average value of its portfolio.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by investing, under normal market conditions, at least 80% of its assets directly or indirectly in the securities included in the Nasdaq Victory International 500 Long/Cash Volatility Weighted Index (the "Index"), an unmanaged, volatility weighted index maintained exclusively by Nasdaq Inc. (the "Index Provider"). The Index Provider is not affiliated with the Fund or the Adviser.

The Index combines fundamental criteria with individual security risk control achieved through volatility weighting of individual securities. In accordance with a rules-based mathematical formula, the Index tactically reduces its exposure to the equity markets during periods of significant market decline and reallocates to stocks when market prices have further declined or rebounded. The term "Enhanced" in the Fund's name refers to a feature of the Index that is designed to enhance risk-adjusted returns while attempting to minimize downside market risk through defensive positioning, as described below.

The Index follows a rules-based methodology to construct its constituent securities:

•  The Index universe begins with all publicly traded foreign companies and then screens for all companies with positive earnings in each of the four most recent quarters.

•  The Index identifies the 500 largest foreign companies by market capitalization measured at the time the Index's constituent securities are determined.

•  The 500 stocks are weighted based on their daily standard deviation (volatility) of daily price changes over the last 180 trading days. Stocks with lower volatility receive a higher weighting and stocks with higher volatility receive a lower weighting.

The Index considers foreign companies to be those that are organized or domiciled in a developed country (excluding the U.S. and emerging markets) and whose stock principally trades on a foreign exchange. Representative developed markets include Canada, France, Germany, Japan, Hong Kong and Australia.

The Index is reconstituted every March and September (based on information as of the prior month-end) and is adjusted to limit exposure to any particular country to 20% and any particular sector to 25%. The Index may include more than or fewer than 500 stocks depending on the number of companies meeting the Index's criteria.

The Index follows a mathematical index construction process designed to limit risk during periods of significant (non-normal) market decline by reducing its exposure to the equity market. Market decline is measured by reference to the Nasdaq Victory International 500 Volatility Weighted Index ("Reference Index"), which is composed of the same securities as in the Index but without any allocation to cash.

During a period of significant market decline, defined as a decline of 12% or more from the Reference Index's all-time daily high closing value compared to its most recent month-end closing value, the Index's exposure to the market may be as low as 25% depending on the magnitude and duration of such decline.

If the month-end value of the Reference Index declines 12% or more from its all-time closing high, the Index will reallocate 75% of the stocks included in the Index to cash or cash equivalents.

The Index will reallocate to stocks as follows:

•  The Index will return to being 100% allocated to stocks if the month-end closing value of the stocks in the Reference Index returns to a level that is less than a 12% decline from its all-time daily high closing value.

•  If the Reference Index declines by 24% (or more) from its all-time daily high closing value as measured at month-end, 25% of the Index will reallocate to the stocks of the Reference Index at their current securities weightings.

•  If the Reference Index declines by 36% (or more) from its all-time daily high closing value as measured at month-end, another 25% of the Index will reallocate to the stocks of the Reference Index at their current securities weightings.

•  If the Reference Index declines by 48% (or more) from its all-time daily high closing value as measured at month-end, the remaining 25% of the Index will reallocated to the stocks of the Reference Index at their current securities weighting and the Index will then be 100% allocated to stocks.

The Index will make any prescribed allocations to cash in accordance with the mathematical formula only at month end. In the event that it does, the Fund may experience higher portfolio turnover and incur additional transaction costs.

During any periods of significant market decline, when the Index's exposure to the market is less than 100%, the cash portion of the Index will be allocated to 30-day U.S. Treasury bills. The Fund will invest the portion of its portfolio corresponding to the cash portion of the Index in Treasury bills with a duration generally of 90 days or less or in investment companies, such as money market funds.

The Fund seeks to track the returns of the Index before fees and expenses by employing, under normal circumstances, a "sampling" process to invest in a representative sample of stocks included in the Index. The Fund's portfolio managers select these stocks using a statistical optimization process designed to produce investment characteristics that closely approximate those of the Index. At times the Fund may pursue its investment objective by investing in the Index securities indirectly by investing all or a portion of its assets in another investment company advised by the Adviser, including an exchange-traded fund ("ETF") that seeks to track the Index or the Reference Index.

Principal Risks of Investing in the Fund

The Fund's investments are subject to the following principal risks:

nEquity Risk — The value of the equity securities in which the Fund invests may decline in response to developments affecting individual companies and/or general economic conditions. A company's earnings or dividends may not increase as expected. Price changes may be temporary or last for extended periods.

nETF Structure Risks — The Fund is structured as an ETF and as a result is subject to special risks, including:

nNot Individually Redeemable — The Fund's shares ("Shares") are not individually redeemable and may be redeemed by the Fund at its net asset value per share ("NAV") only in large blocks known as "Creation Units." You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit. Alternatively, you may redeem your Shares by selling them on the secondary market at prevailing market prices.

nTrading Issues — Trading in Shares on the Exchange (as defined below) may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. There is no guarantee that an active secondary market will develop for the Shares. In stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund's underlying portfolio holdings, which may lead to differences between the market price of the Shares and the underlying value of those Shares.

n  Market Price Variance Risk — The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a "bid-ask spread" charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a premium or discount to NAV.

n  International Closed Market Trading Risk — Many of the Fund's underlying securities trade on foreign exchanges that are closed when the Exchange (as defined below) is open; consequently, events may transpire while such foreign exchanges are closed but the Exchange is open that may change the value of such underlying securities relative to their last quoted prices on such foreign exchanges. Because the Fund generally relies on the last quoted prices for such securities when calculating its NAV, such events may cause Shares to trade at a premium or discount to NAV.

n  Authorized Participants Concentration Risk — A limited number of financial institutions may be responsible for all or a significant portion of the creation and redemption activity for the Fund. If these firms exit the business or are unable to process creation and/or redemption orders, Shares may trade at a premium or discount to NAV.

n  Intraday Indicative Value (IIV) Risk — The Exchange intends to disseminate the approximate per share value of the Fund's published basket of securities ("Deposit Securities") every 15 seconds (the "intraday indicative value" or "IIV''). The IIV is not a "real-time" update of the NAV per share of the Fund because the IIV may not be calculated in the same manner as the NAV. For example, the calculation of the NAV may be subject to fair valuation at different prices than those used in the calculations of the IIV and, unlike the calculation of NAV, the IIV does not take into account Fund expenses. The IIV calculations are based on local market prices and may not reflect events that occur subsequent to the local market's close which could affect premiums and discounts between the IIV and the market price of the Shares. In addition, the IIV is based on the published Deposit Securities and not on the Fund's actual holdings.

n  Fixed Income Risk — The value of the Fund's direct or indirect investments in fixed income securities changes in response to various factors, including, for example, market-related factors (such as changes in interest rates or changes in the risk appetite of investors generally) and changes in the actual or perceived ability of the issuer (or of issuers generally) to meet its (or their) obligations.

n  Foreign Investment Risk

nForeign Exposure Risk — Special risks associated with investments in foreign markets may include less liquidity, greater volatility, less developed or less efficient trading markets, lack of comprehensive company information, political instability and differing auditing and legal standards.

nCurrency Risk — The Fund's net asset value could decline as a result of changes in the exchange rates between foreign currencies and the US dollar. Additionally, certain foreign countries may impose restrictions on the ability of issuers of foreign securities to make payment of principal and interest to investors located outside the country, due to blockage of foreign currency exchanges or otherwise.

n  Index/Defensive Positioning Risk — Because the Index's allocation to cash versus securities is determined at month-end, there is a risk that the Index, and thus the Fund, will not react to changes in market conditions that occur between reallocations. The Fund will incur transaction costs and potentially adverse tax consequences in the event the Index allocates to cash. There is no guarantee that the Index's prescribed liquidation and reinvestment strategy, if employed, will be successful in minimizing downside market risk.

n  Investment Company Risk — An investment company (including an ETF) or similar vehicle in which the Fund invests may not achieve its investment objective. Underlying investment vehicles are subject to investment advisory and other expenses, which will be indirectly paid by the Fund. Lack of liquidity in an ETF could result in an ETF being more volatile than the underlying portfolio of securities.

n  Limited History of Operations — The Fund is a new ETF and, therefore, has a limited history of operations for investors to evaluate.

n  Passive Investment Risk — The Fund is designed to track the Index and is not actively managed. The Fund will not buy or sell shares of an equity security due to current or projected performance of a security, industry or sector, unless that security is added to or removed, respectively, from the Index.

The Fund does not, therefore, seek returns in excess of the Index, and does not attempt to take defensive positions or hedge against potential risks unless such defensive positions are also taken by the applicable Index.

n  Portfolio Turnover Risk — Higher portfolio turnover ratios resulting from additional purchases and sales of portfolio securities will generally result in higher transaction costs and Fund expenses and may result in more significant distributions of short-term capital gains to investors, which are taxed as ordinary income.

n  Sampling Risk — The Fund's use of a representative sampling approach, if used, could result in its holding a smaller number of securities than are in the Index. As a result, an adverse development with an issuer or a small number of issuers of securities held by the Fund could result in a greater decline in NAV than would be the case if the Fund held all of the securities of the Index. To the extent the assets in the Fund are similar, these risks will be greater.

n  Tracking Risk — The Fund's return may not match the return of the Index for a number of reasons, including: the Fund incurs operating expenses not applicable to the Index, and incurs costs in buying and selling securities; the Fund may not be fully invested at times; differences in the valuation of securities; and differences between the Fund's portfolio and the Index resulting from legal restrictions, cost, or liquidity constraints. The Fund's use of representative sampling may cause the tracking error to be higher than would be the case if the Fund purchased all of the securities in the Index.

You may lose money by investing in the Fund. There is no guarantee that the Fund will achieve its objective. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Company (FDIC) or any other government agency.

By itself, the Fund does not constitute a complete investment plan and should be considered a long-term investment for investors who can afford to weather changes in the value of their investment.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its investment objective by investing, under normal market conditions, at least 80% of its assets directly or indirectly in the securities included in the Nasdaq Victory International 500 Long/Cash Volatility Weighted Index (the "Index"), an unmanaged, volatility weighted index maintained exclusively by Nasdaq Inc. (the "Index Provider"). The Index Provider is not affiliated with the Fund or the Adviser.

The Index combines fundamental criteria with individual security risk control achieved through volatility weighting of individual securities. In accordance with a rules-based mathematical formula, the Index tactically reduces its exposure to the equity markets during periods of significant market decline and reallocates to stocks when market prices have further declined or rebounded. The term "Enhanced" in the Fund's name refers to a feature of the Index that is designed to enhance risk-adjusted returns while attempting to minimize downside market risk through defensive positioning, as described below.

The Index follows a rules-based methodology to construct its constituent securities:

•  The Index universe begins with all publicly traded foreign companies and then screens for all companies with positive earnings in each of the four most recent quarters.

•  The Index identifies the 500 largest foreign companies by market capitalization measured at the time the Index's constituent securities are determined.

•  The 500 stocks are weighted based on their daily standard deviation (volatility) of daily price changes over the last 180 trading days. Stocks with lower volatility receive a higher weighting and stocks with higher volatility receive a lower weighting.

The Index considers foreign companies to be those that are organized or domiciled in a developed country (excluding the U.S. and emerging markets) and whose stock principally trades on a foreign exchange. Representative developed markets include Canada, France, Germany, Japan, Hong Kong and Australia.

The Index is reconstituted every March and September (based on information as of the prior month-end) and is adjusted to limit exposure to any particular country to 20% and any particular sector to 25%. The Index may include more than or fewer than 500 stocks depending on the number of companies meeting the Index's criteria.

The Index follows a mathematical index construction process designed to limit risk during periods of significant (non-normal) market decline by reducing its exposure to the equity market. Market decline is measured by reference to the Nasdaq Victory International 500 Volatility Weighted Index ("Reference Index"), which is composed of the same securities as in the Index but without any allocation to cash.

During a period of significant market decline, defined as a decline of 12% or more from the Reference Index's all-time daily high closing value compared to its most recent month-end closing value, the Index's exposure to the market may be as low as 25% depending on the magnitude and duration of such decline.

If the month-end value of the Reference Index declines 12% or more from its all-time closing high, the Index will reallocate 75% of the stocks included in the Index to cash or cash equivalents.

The Index will reallocate to stocks as follows:

•  The Index will return to being 100% allocated to stocks if the month-end closing value of the stocks in the Reference Index returns to a level that is less than a 12% decline from its all-time daily high closing value.

•  If the Reference Index declines by 24% (or more) from its all-time daily high closing value as measured at month-end, 25% of the Index will reallocate to the stocks of the Reference Index at their current securities weightings.

•  If the Reference Index declines by 36% (or more) from its all-time daily high closing value as measured at month-end, another 25% of the Index will reallocate to the stocks of the Reference Index at their current securities weightings.

•  If the Reference Index declines by 48% (or more) from its all-time daily high closing value as measured at month-end, the remaining 25% of the Index will reallocated to the stocks of the Reference Index at their current securities weighting and the Index will then be 100% allocated to stocks.

The Index will make any prescribed allocations to cash in accordance with the mathematical formula only at month end. In the event that it does, the Fund may experience higher portfolio turnover and incur additional transaction costs.

During any periods of significant market decline, when the Index's exposure to the market is less than 100%, the cash portion of the Index will be allocated to 30-day U.S. Treasury bills. The Fund will invest the portion of its portfolio corresponding to the cash portion of the Index in Treasury bills with a duration generally of 90 days or less or in investment companies, such as money market funds.

The Fund seeks to track the returns of the Index before fees and expenses by employing, under normal circumstances, a "sampling" process to invest in a representative sample of stocks included in the Index. The Fund's portfolio managers select these stocks using a statistical optimization process designed to produce investment characteristics that closely approximate those of the Index. At times the Fund may pursue its investment objective by investing in the Index securities indirectly by investing all or a portion of its assets in another investment company advised by the Adviser, including an exchange-traded fund ("ETF") that seeks to track the Index or the Reference Index.
