Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	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 and may result in higher taxes when Fund 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 37% of the average value of its portfolio.
Portfolio Turnover, Rate	rr_PortfolioTurnoverRate	37.00%
Expenses Deferred Charges [Text Block]	rr_ExpensesDeferredChargesTextBlock	A contingent deferred sales charge of 0.75% may be imposed on Class A shares with respect to purchases of $1,000,000 or more that are redeemed within 18 months of purchase.

Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	The following example is designed to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods shown and then sell or continue to hold 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 any fee waiver/expense reimbursement in place through its expiration date. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy [Heading]	rr_StrategyHeading	<span style="color:#000000;font-family:Arial;font-size:13.12pt;font-weight:bold;margin-left:0%;">Principal Investment Strategy</span>
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Adviser pursues the Fund's investment objective by investing primarily in the equity securities of smaller companies that the Adviser believes to be undervalued relative to the underlying earnings potential of the company.Under normal circumstances, the Fund will invest at least 80% of its assets in equity securities of small companies. “Small companies” are companies that at the time of purchase have market capitalizations within the range of companies comprising the Russell 2000® Value Index. As of December 31, 2020, the Russell 2000® Value Index included companies with approximate market capitalizations between $43 million and $15.5 billion. The size of companies in the index changes with market conditions and the composition of the index.The Adviser invests in companies that it believes to be of high quality based on criteria such as market share position, profitability, balance sheet strength, competitive advantages, management competence and the ability to generate excess cash flow. The Adviser uses a bottom-up investment process in conducting fundamental analysis to identify companies that have sustainable returns trading below the Adviser’s assessment of intrinsic value and prospects for an inflection in business fundamentals that will enable the stock price to be revalued higher. The Adviser may sell a security if it believes the stock has reached its fair value estimate, if a more attractive opportunity is identified, or if the fundamentals of the company deteriorate.The Fund may invest a portion of its assets in equity securities of foreign companies traded in the U.S., including American Depositary Receipts and Global Depositary Receipts (ADRs and GDRs).As a result of the bottom-up stock selection process, the Fund managers from time to time may find more compelling investment opportunities in certain economic sectors, such as the financials and industrials sectors.
Risk [Heading]	rr_RiskHeading	<span style="color:#000000;font-family:Arial;font-size:13.12pt;font-weight:bold;margin-left:0%;">Principal Risks</span>
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	The Fund’s investments are subject to the following principal risks:Equity 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 in the United States or abroad. A company’s earnings or dividends may not increase as expected (or may decline) because of poor management, competitive pressures, reliance on particular suppliers or geographical regions, labor problems or shortages, corporate restructurings, fraudulent disclosures, man-made or natural disasters, military confrontations or wars, terrorism, public health crises, or other events, conditions and factors. Price changes may be temporary or last for extended periods.Stock Market Risk — Overall stock market risks may affect the value of the Fund. Domestic and international factors such as political events, war, trade disputes, interest rate levels and other fiscal and monetary policy changes, pandemics and other public health crises and related geopolitical events, as well as environmental disasters such as earthquakes, fires and floods, may add to instability in world economies and markets generally. The impact of these and other factors may be short-term or may last for extended periods.Small-Capitalization Stock Risk — Small-sized capitalization companies are 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.Sector Risk — To the extent the Fund focuses in one or more sectors, such as the financials sector, market or economic factors impacting those sectors could have a significant effect on the value of the Fund’s investments and could make the Fund’s performance more volatile.◼Financials Sector Risk — The Fund’s investments in companies within the financials sector means that market or economic factors impacting that sector could have a significant effect on the value of the Fund’s investments and could make the Fund’s performance more volatile. Financial companies, such as retail and commercial banks, insurance companies and financial services companies, are especially subject to the adverse effects of economic recession, currency exchange rates, extensive government regulation, decreases in the availability of capital, volatile interest rates, portfolio concentrations in geographic markets, industries or products (such as commercial and residential real estate loans) and competition from new entrants in their fields of business.◼Industrials Sector Risk — Companies in the industrials sector are affected by supply and demand both for their specific product or service and for industrials sector products in general. Government regulation, world events and economic conditions also affect the performance of investments in such issuers. Aerospace and defense companies, a component of the industrials sector, can be significantly affected by government spending policies. Transportation companies may experience occasional sharp price movements which may result from changes in the economy, fuel prices, labor agreements and insurance costs.Investment Style Risk — Different types of investment styles, for example growth or value, tend to perform differently and shift into and out of favor with investors depending on changes in market and economic sentiment and conditions. As a result, the Fund’s performance may at times be worse than the performance of other mutual funds that invest more broadly or that have different investment styles.Foreign Securities Risk — Foreign securities (including depositary receipts) are subject to political, regulatory, and economic risks not present in domestic investments. Foreign securities could be affected by factors not present in the U.S., including expropriation, confiscation of property, and difficulties in enforcing contracts. Compared to U.S. companies, there generally is less publicly available information about foreign companies and there may be less governmental regulation and supervision of foreign companies. Foreign securities generally experience more volatility than their domestic counterparts. In addition, to the extent investments are made in a limited number of countries, events in those countries will have a more significant impact on the Fund. Fluctuations in the exchange rates between the U.S. dollar and foreign currencies, currency exchange control regulations, and restrictions or prohibitions on the repatriation of foreign currencies may negatively affect an investment.Liquidity 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 investments and relatively less liquid investments may also be difficult to value. Liquidity risk may also refer to the risk that the Fund may not be able to pay redemption proceeds within the allowable time period because of unusual market conditions, unusually high volume of redemptions, or other reasons. To meet redemption requests or to raise cash to pursue other investment opportunities, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions, which may adversely affect the Fund.Management Risk — The portfolio managers may not execute the Fund's principal investment strategy effectively.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 Corporation (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.

[2] Victory Capital Management Inc., the Fund’s investment adviser, (“Adviser”) has contractually agreed to waive its management fee and/or reimburse expenses so that the total annual operating expenses (excluding certain items such as interest, taxes and brokerage commissions) do not exceed 1.15% of the Fund's Class Y shares through at least February 28, 2022. The Adviser is permitted to recoup advisory fees waived and expenses reimbursed 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, after giving effect to the recoupment amount. This agreement may only be terminated by the Fund’s Board of Trustees.
