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. For the most recent fiscal year, the Fund’s portfolio turnover rate was 75% of the average value of its portfolio.
Portfolio Turnover, Rate	rr_PortfolioTurnoverRate	75.00%
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. For additional information, see the section titled Choosing a Share Class.Applies to shares sold within 12 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;">Principal Investment Strategy</span>
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Adviser pursues the Fund’s investment objective by investing, under normal circumstances, in a portfolio of small- and mid-capitalization growth-oriented companies. The Fund typically invests in equity securities of U.S. companies but may also invest any portion of its assets in foreign securities, including depositary receipts such as American Depositary Receipts (“ADRs”) and Global Depositary Receipts (“GDRs”).The Fund principally invests in equity securities of companies with market capitalizations (at the time of purchase) less than $8 billion or 120% of the market capitalization of the largest company included in the Russell 2500® Index (“Index”) (currently, approximately $48.0 billion, based on the size of the largest company in the Index on March 31, 2022), whichever is greater. The size of companies in the Index changes with market conditions and the composition of the Index. The Fund may hold investments in companies whose market capitalizations fall outside these parameters due to changes in market values of those companies after the Fund’s investment in those companies.The Adviser employs both fundamental analysis and quantitative screening in seeking to identify companies that it believes will produce sustainable earnings growth over a multi-year horizon. Investment candidates typically exhibit some or all of the following key criteria: strong organic revenue growth, expanding margins and profitability, innovative products or services, defensible competitive advantages, growing market share, and experienced management teams. Valuation is an integral part of the investment process and purchase decisions are based on the Adviser’s expectation of the potential reward relative to risk of each security based in part on the investment team’s proprietary earnings calculations.The Adviser regularly reviews the Fund’s investments and will sell securities when the Adviser believes the securities are no longer attractive because (1) of a deterioration in rank of the security in accordance with the Adviser’s process, (2) of price appreciation, (3) of a change in the fundamental outlook of the company or (4) other investments available are considered to be more attractive.As a result of the Adviser’s investment process, the Fund’s investments may be focused in one or more economic sectors from time to time, including the information technology sector.
Risk [Heading]	rr_RiskHeading	<span style="color:#000000;font-family:Arial;font-size:13.12pt;font-weight:bold;">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.Smaller-Capitalization Stock Risk — Small- and mid-sized 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.Limited Portfolio Risk — To the extent the Fund invests its assets in a more limited number of issuers than many other funds, a decline in the market value of a particular security may affect the Fund's value more than if the Fund invested in a larger number of issuers.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. Depositary receipts may have additional risks, including creditworthiness of the depositary bank and the risk of an illiquid market. 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.Sector Focus Risk — While the Fund reserves the right to dynamically allocate its assets across economic sectors, listed below are some of the risks associated with investments in the sectors in which the Fund has made significant investments as of the date of this Prospectus. 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.◼Information Technology Risk — Information Technology companies tend to significantly rely on technological events or advances in their product development, production or operations and are particularly vulnerable to rapid changes in technological product cycles, government regulation and competition.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 an investment that is large relative to the typical trading volume for that investment, 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 investments at an unfavorable time and/or under unfavorable conditions, which may adversely affect the Fund.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.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.

Performance Narrative [Text Block]	rr_PerformanceNarrativeTextBlock	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 of the Fund's share classes, including applicable maximum sales charges, over the same period to one or more broad measures of market performance, which have characteristics relevant to the Fund’s investment strategy. We assume reinvestment of dividends and distributions.Performance data for the classes varies based on differences in their fee and expense structures and reflects any expense limitations in effect during the periods shown. The Fund's past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future. Updated performance information is available on the Fund’s website at VictoryFunds.com.Performance information for the Fund’s Class A, C, R and Y shares prior to July 30, 2016 reflects the historical performance of, respectively, the Class A, C, K and Y shares of the RS Select Growth Fund, a series of RS Investment Trust (the predecessor to the Fund managed by RS Investment Management Co. LLC) (the “predecessor fund”). The Fund’s performance has not been restated to reflect any differences in expenses paid by the predecessor fund and those paid by the Fund.
