Touchstone Core Municipal Bond Fund Investment Risks - Touchstone Core Municipal Bond Fund	Jun. 30, 2026
Fixed-Income Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Fixed-Income Risk: The market value of the Fund’s fixed-income securities responds to economic developments, particularly interest rate changes, as well as to perceptions about the creditworthiness of individual issuers, including governments. Generally, the Fund’s fixed-income securities will decrease in value if interest rates rise and increase in value if interest rates fall. Normally, the longer the maturity or duration of the fixed-income securities the Fund owns, the more sensitive the value of the Fund’s shares will be to changes in interest rates.
Credit Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	●Credit Risk: The fixed-income securities in the Fund’s portfolio are subject to the possibility that a deterioration, whether sudden or gradual, in the financial condition of an issuer, or a deterioration in general economic conditions, could cause an issuer to fail to make timely payments of principal or interest, when due. This may cause the issuer’s securities to decline in value.
Interest Rate Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	●Interest Rate Risk: In general, when interest rates rise, the prices of debt securities fall, and when interest rates fall, the prices of debt securities rise. The price volatility of a debt security also depends on its maturity. Longer-term securities are generally more volatile, so the longer the average maturity or duration of these securities, the greater their price risk. Duration is a measure used to determine the sensitivity of a security’s price to changes in interest rates that incorporates a security’s yield, coupon, final maturity, and call features, among other characteristics. The longer a fixed-income security’s duration, the more sensitive it will be to changes in interest rates. Maturity, on the other hand, is the date on which a fixed-income security becomes due for payment of principal. Recent and potential future changes in government policy may affect interest rates.
Investment-Grade Debt Securities Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	●Investment-Grade Debt Securities Risk: Investment-grade debt securities may be downgraded by a NRSRO to below-investment-grade status, which would increase the risk of holding these securities. Investment-grade debt securities rated in the lowest rating category by a NRSRO involve a higher degree of risk than fixed-income securities with higher credit ratings.
Prepayment Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	●Prepayment Risk: The risk that a debt security may be paid off and proceeds reinvested earlier than anticipated. Prepayment impacts both the interest rate sensitivity of the underlying asset, such as an asset-backed or mortgage-backed security and its cash flow projections. Therefore, prepayment risk may make it difficult to calculate the average duration of the Fund’s asset- or mortgage-backed securities which in turn would make it difficult to assess the interest rate risk of the Fund.
US Government Securities Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	●U.S. Government Securities Risk: Certain U.S. government securities are backed by the right of the issuer to borrow from the U.S. Treasury while others are supported only by the credit of the issuer or instrumentality. While the U.S. government is able to provide financial support to U.S. government-sponsored agencies or instrumentalities, no assurance can be given that it will always do so. Such securities are generally neither issued nor guaranteed by the U.S. Treasury.
Municipal Securities Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Municipal Securities Risk: The value of municipal securities may be affected by uncertainties in the municipal market related to legislation or litigation involving the taxation of municipal securities or the rights of municipal securities holders in the event of bankruptcy. In addition, a downturn in the national economy may negatively impact the economic performance of issuers of municipal securities, and may increase the likelihood that issuers of securities in which the Fund may invest may be unable to meet their obligations. Also, some municipal obligations may be backed by a letter of credit issued by a bank or other financial institution. Adverse developments affecting banks or other financial institutions could have a negative effect on the value of the Fund’s portfolio securities. In order to be tax exempt, tax-exempt securities must meet certain legal requirements. Failure to meet such requirements may cause the interest received and distributed by the Fund to shareholders to be taxable. The Fund may invest in securities whose interest is subject to state tax, federal regular income tax, or federal alternative minimum tax. Consult your tax professional for more information.
Management Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Management Risk: In managing the Fund’s portfolio, the Adviser engages one or more sub-advisers to make investment decisions for a portion of or the entire portfolio. There is a risk that the Adviser may be unable to identify and retain sub-advisers who achieve superior investment returns relative to other similar sub-advisers.
Economic and Market Events Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Economic and Market Events Risk: Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times, and for varying periods of time, result in unusually high market volatility, which could negatively impact the Fund’s performance and cause the Fund to experience illiquidity, shareholder redemptions, or other potentially adverse effects. Reduced liquidity in credit and fixed-income markets could negatively affect issuers worldwide. Financial institutions could suffer losses as interest rates rise or economic conditions deteriorate. In addition, the Fund’s service providers are susceptible to operational and information or cybersecurity risks that could result in losses to a Fund and its shareholders.
ESG Investing Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	ESG Investing Risk: The Fund's sub-adviser may consider ESG factors that it deems relevant or additive, along with other material factors and analysis, when selecting investments for the Fund. The Fund’s ESG criteria may cause the Fund to forgo opportunities to buy certain securities, or forgo opportunities to gain exposure to certain industries, sectors, regions and countries. In addition, the Fund may be required to sell a security when it might otherwise be disadvantageous for it to do so.
Cyber Security Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Cybersecurity Risk: Cybersecurity breaches are either intentional or unintentional events that allow an unauthorized party to gain access to Fund assets, customer data, or proprietary information, or cause a Fund or Fund service provider to suffer data corruption or lose operational functionality. A cybersecurity breach could result in the loss or theft of customer data or funds, loss or theft of proprietary information or corporate data, physical damage to a computer or network system, or costs associated with system repairs, any of which could have a substantial impact on the Fund. Such incidents could affect issuers in which a Fund invests, thereby causing the Fund’s investments to lose value. The Fund has established risk management systems reasonably designed to seek to reduce the risks associated with cyber-events. However, there is no guarantee that the Fund will be able to prevent or mitigate the impact of any or all cyber-events.
Risk Lose Money [Member]
