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 19% of the average value of its portfolio.

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 Fund invests primarily in municipal obligations, the interest on which is, in the opinion of the issuer’s bond counsel, exempt from federal individual income tax (but not necessarily the federal alternative minimum tax (the “AMT”)). Under normal circumstances at least 80% of the value of the Fund’s assets will be invested in tax-exempt municipal obligations (which may include obligations that pay interest subject to the AMT). This is a fundamental policy that cannot be changed without shareholder approval.The Adviser allocates the Fund’s investments among a diversified portfolio of municipal securities offering the potential for high current income. The Fund may invest any portion of its assets in municipal securities that are rated below investment grade (or, if unrated, considered by the Adviser to be of comparable quality), commonly known as “high yield” or “junk” bonds.In selecting securities for the Fund, the Adviser performs in-depth credit analysis of the issuer’s creditworthiness and of the securities. The Adviser attempts to identify securities paying attractive current income, and securities that it believes are undervalued.The Adviser considers the duration and the maturity of the Fund’s portfolio; however, these factors are a lesser consideration than credit and yield considerations due to the nature of the securities in which the Fund invests. There is no lower limit on the rating of securities that may be in the Fund. Some of the securities that the Fund buys and holds may be in default.The Adviser may sell investments when it believes that they no longer offer attractive potential future returns compared to other investment opportunities or that they present undesirable risks, or in an attempt to limit losses on investments that may decline or have declined in value.The Fund may invest up to 100% of its assets in high yield, lower-rated fixed-income securities, including securities below investment grade, commonly known as “high yield” or “junk” bonds. A security will be considered to be below investment grade if it is rated Ba1 or lower by Moody’s Investors Service, Inc. and BB+ or lower by Standard & Poor’s Ratings Group, or if unrated, is considered by the Adviser to be of comparable quality. A below investment grade rating reflects a greater possibility that the issuer of an investment may be unable to make timely payments of interest and principal and thus default. If this happens, or is perceived as likely to happen, the value of that investment will usually be more volatile and is likely to fall.The Fund may invest in other tax-exempt securities that are not municipal obligations. The Fund’s investments may include any type of debt instrument, including, for example, zero-coupon securities, floating and variable-rate demand notes and bonds, and residual interest bonds, which are an inverse floating rate security (“inverse floaters”). The Fund may invest any portion of its assets in obligations that pay interest subject to the AMT.The Fund may invest without limit in municipal obligations that pay interest from similar revenue sources, in municipal securities of issuers within a single state, or in municipal securities issued by entities having similar characteristics. The issuers may be located in the same geographic areas or may pay their interest obligations from revenue of similar projects, such as hospitals, airports, utility systems and housing finance agencies. The Fund may invest more than 25% of its total assets in a segment of the municipal securities market with similar characteristics if the Fund’s investment team determines that the potential return from such investment justifies the additional risk.The Fund may enter into exchange-traded or over-the-counter derivatives transactions of any kind, such as futures contracts, options on futures, and swap contracts, including, for example, interest rate swaps and credit default swaps. The Fund may enter into any of these transactions for a variety of purposes, including, but not limited to, hedging various risks such as credit risk, interest rate risk, and liquidity risk; taking a net long or short position in certain investments or markets; providing liquidity in the Fund; equitizing cash; minimizing transaction costs; generating income; adjusting the Fund’s sensitivity to interest rate risk or other risk; replicating certain direct investments; and asset and sector allocation.
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:Debt Securities Risk — The value of a debt security or other income-producing security 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. Other factors that may affect the value of debt securities, include, among others, public health crises and responses by governments and companies to such crises. These and other events may affect the creditworthiness of the issuer of a debt security and may impair an issuer's ability to timely meet its debt obligations as they come due.Municipal Obligations Risk – The values of municipal obligations that depend on a specific revenue source to fund their payment obligations may fluctuate as a result of changes in the cash flows generated by the revenue source or changes in the priority of the municipal obligation to receive the cash flows generated by the revenue source. Changes in the financial health of a municipality or other issuer, or an insurer of municipalities, may make it difficult to pay interest and principal when due and may affect the overall municipal securities market. Municipal obligations concentrated in a particular geographic region may make the Fund’s investments more susceptible to economic, political, regulatory, or other factors affecting issuers in those geographic areas and may increase the volatility of the Fund’s net asset value. In addition, changes in federal tax laws or the activity of an issuer may adversely affect the tax-exempt status of municipal obligations. Loss of tax-exempt status may cause interest received and distributed to shareholders by the Fund to be taxable and may result in a significant decline in the values of such municipal obligations. Investments in inverse floaters typically involve greater risk than investments in municipal obligations of comparable maturity and credit quality, and the values of inverse floaters are more volatile than those of municipal obligations due to the leverage they entail.High-Yield/Junk Bond Risk — Lower-quality debt securities can involve a substantially greater risk of default than higher quality debt securities, and their values can decline significantly over short and longer periods of time. Lower-quality debt securities tend to be more sensitive to adverse news about the issuer, or the market or economy in general.Derivatives Risk — Derivative instruments and strategies, including  futures and selling securities short, may not perfectly replicate direct investment in the security. Derivatives also entail exposure to counterparty credit risk, the risk of mispricing or improper valuation, and the risk that small price movements can result in substantial gains or losses.Credit Derivatives Risk – Credit default swaps can create investment leverage and may create additional investment risks that may subject the Fund to greater volatility than investments in more traditional securities.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 judgement 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, particularly during abnormal market conditions when redemption activity may be high. Illiquid investments and relatively less liquid investments may also be difficult to value. 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. Over recent years, the capacity of dealers to make markets in fixed income securities has been outpaced by the growth in the size of the fixed income markets. Liquidity risk may be magnified in a rising interest rate environment or when investor redemptions from fixed income funds may be higher than normal due to the increased supply in the market that would result from selling activity.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 and Y shares prior to July 30, 2016 reflects the historical performance of, respectively, the Class A, C and Y shares of the RS High Income Municipal Bond Fund, a series of RS Investment Trust (the predecessor to the Fund managed by RS Investment Management Co. LLC and sub-advised by a different manager) (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. The Fund’s investment team changed on April 1, 2020.
