Touchstone Ohio Tax-Free Bond Fund (Prospectus Summary) | Touchstone Ohio Tax-Free Bond Fund

TOUCHSTONE OHIO TAX-FREE BOND FUND SUMMARY

The Fund's Investment Goal

The Touchstone Ohio Tax-Free Bond Fund (the “Fund”) seeks the highest level of interest income exempt from federal income tax and Ohio personal income tax, consistent with the protection of capital.

The Fund's Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund.  You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 or more in the Touchstone Funds.  More information about these and other discounts is available from your financial professional and in the section entitled “Choosing a Class of Shares” in the Fund's prospectus on page 23 and in the Fund's Statement of Additional Information (“SAI”) on page 37.

Example.

This example is intended 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 indicated and then, except as indicated, 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 (reflecting any one-year contractual fee waiver).  Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example Touchstone Ohio Tax-Free Bond Fund (USD $)	Ohio Tax-Free Bond Fund Class A	Ohio Tax-Free Bond Fund Class C
Expense Example, With Redemption, 1 Year	558	263
Expense Example, With Redemption, 3 Years	782	587
Expense Example, With Redemption, 5 Years	1,025	1,037
Expense Example, With Redemption, 10 Years	1,720	2,285

Assuming No Redemption

Expense Example, No Redemption (USD $)	Touchstone Ohio Tax-Free Bond Fund Ohio Tax-Free Bond Fund Class C
Expense Example, No Redemption, 1 Year	163
Expense Example, No Redemption, 3 Years	587
Expense Example, No Redemption, 5 Years	1,037
Expense Example, No Redemption, 10 Years	2,285

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 rate may 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 year, the Fund's portfolio turnover rate was 24% of the average value of its portfolio.

The Fund's Principal Investment Strategies

The Fund invests at least 80% of its assets in high-quality, long-term Ohio municipal obligations, including general obligation bonds, revenue bonds, and industrial development bonds.  High-quality, long-term Ohio municipal obligations are, for purposes of this Fund, considered to be obligations rated within the three highest rating categories, with remaining maturities of 3 years or more.  This is a non-fundamental investment policy and the Fund will provide shareholders with at least 60-days prior notice of any change in this policy.

The Fund concentrates its investments in securities of issuers located in the State of Ohio and is non-diversified under the Investment Company Act of 1940, as amended (the “1940 Act”).  The Fund invests primarily in Ohio municipal obligations rated within the three highest rating categories.  The Fund may also purchase Ohio municipal obligations and other securities rated within the four highest rating categories.  If a security's rating is reduced below the four highest rating categories, the security will be sold.  A security may also be sold due to changes in market conditions or Fort Washington Investment Advisors, Inc.'s (“Fort Washington” or “Sub-Advisor”) outlook.  The Fund may purchase unrated obligations that the sub-advisor determines to be of comparable quality.  The Fund will seek to maintain an average weighted maturity of more than 10 years, but may reduce its average weighted maturity to 10 years or below if warranted by market conditions.

The Fund may invest more than 25% of its assets in municipal obligations within a particular segment of the bond market (such as housing agency bonds or airport bonds).  The Fund may also invest more than 25% of its assets in private activity bonds and industrial development bonds which may be backed only by nongovernmental entities.  Under normal circumstances, the Fund will limit its investment in securities whose income is subject to the alternative minimum tax to less than 20% of its assets.  The Fund will not invest more than 25% of its assets in securities backed by nongovernmental entities that are in the same industry.

The Fund has a fundamental investment policy that under normal circumstances at least 80% of the income it distributes will be exempt from federal income tax, including the alternative minimum tax, and Ohio personal income tax. This fundamental policy may not be changed without the approval of the Fund's shareholders.

The Principal Risks

The Fund's share price will fluctuate.  You could lose money on your investment in the Fund and the Fund could return less than other investments.  The Fund is subject to the principal risks summarized below.

Credit Risk: The 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:  As interest rates rise, the value of fixed-income securities the Fund owns will be likely to decrease. 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 of the expected life, taking into account any prepayment or call features of the security, of a fixed-income security that is used to determine the price sensitivity of the security for a given change in interest rates. Specifically, duration is the approximate change in the value of a fixed-income security that will result from a 1% change in interest rates, and generally is stated in years. Maturity, on the other hand, is the date on which a fixed-income security becomes due for payment of principal.

Investment-Grade Debt Securities Risk:  Investment-grade debt securities may be downgraded by a Nationally Recognized Statistical Rating Organization (“NRSRO”) to below investment-grade status, which would increase the risk of holding these securities, or a rating may become stale in that it fails to reflect changes to an issuer's financial condition.  Investment-grade debt securities rated in the lowest rating category by an NRSRO involve a higher degree of risk than fixed-income securities in the higher-rating categories.  While such securities are considered investment-grade quality and are deemed to have adequate capacity for payment of principal and interest, such securities lack outstanding investment characteristics and have speculative characteristics as well.  For example, changes in economic conditions or other circumstances are more likely to lead to a weakened capacity to make principal and interest payments than is the case with higher-grade securities.

Management Risk:  The Advisor engages one or more sub-advisors to make investment decisions for a portion or all of the Fund's portfolio.  There is a risk that the Advisor may be unable to identify and retain sub-advisors who achieve superior investment returns relative to other similar sub-advisors.  The value of your investment may decrease if the sub-advisor's judgment about the attractiveness, value or market trends affecting a particular security, issuer, industry or sector or about market movements is incorrect.

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, the ongoing issues facing 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.

Non-Diversification Risk: The Fund is non-diversified, which means that it may invest a greater percentage of its assets than diversified mutual funds in the securities of a limited number of issuers.  The use of a non-diversified investment strategy may increase the volatility of the Fund's investment performance, as the Fund may be more susceptible to risks associated with a single economic, political or regulatory event than a diversified fund.

Prepayment Risk: Prepayment risk is the risk that a debt security may be paid off and proceeds invested earlier than anticipated. Prepayment risk is more prevalent during periods of falling interest rates.

Sector Focus Risk:  A fund that focuses its investments in the securities of a particular bond market sector (e.g., housing agency bonds or airport bonds) is subject to the risk that adverse circumstances will have a greater impact on the fund than a fund that does not focus its investments in a particular sector.  It is possible that economic, business, or political developments or other changes affecting one security in the area of focus will affect other securities in that area of focus in the same manner, thereby increasing the risk of such investments.

State Risk:  Political and economic conditions in the state of Ohio may impact the value of Ohio municipal obligations.  The Fund may lose value due to decreased economic growth, increased unemployment and decreased tax revenue in the state of Ohio.

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the FDIC or any other government agency.  As with any mutual fund, there is no guarantee that the Fund will achieve its investment goal.  You can find more information about the Fund's investments and risks under the “Investment Strategies and Risks” section in the Fund's prospectus.

The Fund's Performance

The bar chart and performance table below illustrate some indication of the risks of investing in the Fund.  The bar chart shows changes in performance (before taxes) of the Fund's Class A shares for each of the last 10 calendar years.  The bar chart does not reflect any sales charges, which would reduce your return.  Past performance (before and after taxes) does not necessarily indicate how it will perform in the future.  Updated performance is available at no cost by visiting www.TouchstoneInvestments.com or by calling 1.800.543.0407.

Touchstone Ohio Tax-Free Bond Fund - Class A Total Returns as of December 31

The year-to-date return of the Fund's Class A shares as of September 30, 2013 is (2.67)%.

The performance table shows how the Fund's average annual total returns (before and after taxes) for 1 year, 5 years and 10 years compare with those of the Barclays Capital Municipal Bond Index.  After-tax returns are calculated using the highest individual federal income tax rate and do not reflect the impact of state and local taxes.  Your after-tax returns may differ from those shown and depend on your tax situation.  The after-tax returns do not apply to shares held in an IRA, 401(k), or other tax-deferred account.  The after-tax returns shown in the table are for Class A shares only.  The after-tax returns for other classes of shares offered by the Fund will differ from the Class A shares after-tax returns.

[1] Touchstone Advisors, Inc. and the Trust have entered into an expense limitation agreement whereby Touchstone Advisors has contractually agreed to waive a portion of its fees or reimburse certain Fund expenses (excluding dividend expenses relating to short sales, interest, taxes, brokerage commissions, other expenditures which are capitalized in accordance with generally accepted accounting principles, the cost of 'Acquired Fund Fees and Expenses,' if any, and other extraordinary expenses not incurred in the ordinary course of business) in order to limit annual fund operating expenses to 0.85% and 1.60% for Classes A and C shares, respectively. This expense limitation will remain in effect until at least October 29, 2014, but can be terminated by a vote of the Board of Trustees of the Fund (the 'Board') if they deem the termination to be beneficial to the Fund's shareholders. Touchstone Advisors is entitled to recoup, subject to approval by the Board, such amounts reduced or reimbursed for a period of up to three years from the year in which Touchstone Advisors reduced its compensation or assumed expenses for the Fund. No recoupment will occur unless the Fund's expenses are below the expense limitation. See the discussion entitled 'Expense Limitation' under the section entitled 'The Investment Advisor and Sub-Advisor' in the Fund's Statement of Additional Information for more information.

The Fund's Principal Investment Strategies

Investment Strategy, Narrative

rr_StrategyNarrativeTextBlock

The Fund invests primarily in high-quality, short-term municipal obligations that pay interest that is exempt from federal income tax.  High-quality, short-term municipal obligations are obligations rated within the two highest rating categories, with maturities of 397 days or less and that are rated in one of the two highest short-term rating categories or determined by the investment advisor to be of comparable quality.

The Fund has a fundamental investment policy that under normal circumstances it will invest its assets so that at least 80% of the income it distributes will be exempt from federal income tax, including the alternative minimum tax.  This fundamental policy may not be changed without the approval of the Fund's shareholders.

The Fund may invest more than 25% of its assets in municipal obligations within a particular segment of the bond market (such as housing agency bonds or airport bonds).  The Fund may also invest more than 25% of its assets in private activity bonds and industrial development bonds, which may be backed only by nongovernmental entities.  Under normal circumstances, the Fund will limit its investment in securities whose income is subject to the alternative minimum tax to less than 20% of its assets.  The Fund will not invest more than 25% of its assets in securities backed by nongovernmental entities that are in the same industry.

The Fund may invest in the following types of municipal obligations:

·Tax-exempt bonds, including general obligation bonds, revenue bonds and industrial development bonds.

·Tax-exempt notes.

·Tax-exempt commercial paper.

·Floating and variable rate municipal obligations.

·When-issued obligations.

·Obligations with puts attached.

The Fund maintains a dollar-weighted average portfolio maturity of 60 days or less, dollar-weighted average life of 120 days or less, and purchases only United States dollar-denominated securities with maturities of 397 days or less.  The Fund will hold at least 30% of its total assets in “Weekly Liquid Assets” which includes cash (including demand deposits), direct obligations of the U.S. government, agency discount notes with remaining maturities of 60 days or less, and securities (including repurchase agreements) that will mature or are subject to a demand feature that is exercisable and payable within 5 business days.  The Fund is also subject to the quality and diversification requirements of Rule 2a-7 under the Investment Company Act of 1940, as amended, that are designed to help it maintain a constant share price of $1.00 per share.

The Principal Risks

Risk, Narrative

rr_RiskNarrativeTextBlock

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the FDIC or any other government agency.  Although the Fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the Fund.  There is no guarantee that the Fund will be able to avoid a negative yield.  The Fund is subject to the “Principal Risks” summarized below.

Credit Risk:  The 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:  As interest rates rise, the value of fixed income securities the Fund owns will be likely to decrease. 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 of the expected life, taking into account any prepayment or call features of the security, of a fixed income security that is used to determine the price sensitivity of the security for a given change in interest rates. Specifically, duration is the change in the value of a fixed income security that will result from a 1% change in interest rates, and generally is stated in years. Maturity, on the other hand, is the date on which a fixed income security becomes due for payment of principal.

Management Risk:  The Advisor engages one or more sub-advisors to make investment decisions for a portion or all of the Fund's portfolio. There is a risk that the Advisor may be unable to identify and retain sub-advisors who achieve superior investment returns relative to other similar sub-advisors.  The value of your investment may decrease if the sub-advisor incorrectly judges market movements or the attractiveness or value or market trends affecting a particular security, issuer, industry or sector.

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, the ongoing issues facing 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.  This could cause the value of the Fund's shares to decrease to a price less than $1.00 per share.

Sector Focus Risk:  The Fund may focus its investments in certain industries within certain sectors.  A fund that focuses its investments in the securities of a particular market sector is subject to the risk that adverse circumstances will have a greater impact on the fund than a fund that does not focus its investments in a particular sector.  It is possible that economic, business or political developments or other changes affecting one security in the area of focus will affect other securities in that area of focus in the same manner, thereby increasing the risk of such investments.

[1] The Fund is authorized under its Rule 12b-1 plan for Class S shares to pay an annual fee of up to 1.00% of its average daily net assets. The Fund currently intends to limit the amount of Rule 12b-1 fees for Class S shares to a maximum of 0.35% per annum of the average daily net assets of Class S shares.

[2] Touchstone Advisors, Inc. and the Trust have entered into an expense limitation agreement whereby Touchstone Advisors has contractually agreed to waive a portion of its fees and/or reimburse certain Fund expenses (excluding dividend expenses relating to short sales, interest, taxes, brokerage commissions, other expenditures which are capitalized in accordance with generally accepted accounting principles, the cost of 'Acquired Fund Fees and Expenses,' if any, and other extraordinary expenses not incurred in the ordinary course of business) in order to limit annual fund operating expenses to 0.89% and 0.90% for Classes A and S shares, respectively. This expense limitation will remain in effect until at least October 29, 2014, but can be terminated by a vote of the Board of Trustees of the Fund (the 'Board') if they deem the termination to be beneficial to the Fund's shareholders. Touchstone Advisors is entitled to recoup, subject to approval by the Board, such amounts reduced or reimbursed for a period of up to three years from the year in which Touchstone Advisors reduced its compensation and/or assumed expenses for the Fund. No recoupment will occur unless the Fund's expenses are below the expense limitation. See the discussion entitled 'Expense Limitation' under the section entitled 'The Investment Advisor' in the Fund's Statement of Additional Information for more information.

[3] The fee waivers do not correlate to the ratio of net expenses to average net assets shown in the annual report due to an additional voluntary fee waiver. During the last fiscal year, Touchstone Advisors voluntarily waived additional fees or reimbursed certain Fund expenses. Due to the voluntary fee waivers, the Fund's actual ratio of net expenses to average net assets was 0.30% and 0.30% for Class A shares and Class S shares, respectively.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio).  A higher portfolio turnover rate may 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 year, the Fund's portfolio turnover rate was 24% of the average value of its portfolio.

The Fund's Principal Investment Strategies

Investment Strategy, Narrative

rr_StrategyNarrativeTextBlock

The Fund invests at least 80% of its assets in high-quality, long-term Ohio municipal obligations, including general obligation bonds, revenue bonds, and industrial development bonds.  High-quality, long-term Ohio municipal obligations are, for purposes of this Fund, considered to be obligations rated within the three highest rating categories, with remaining maturities of 3 years or more.  This is a non-fundamental investment policy and the Fund will provide shareholders with at least 60-days prior notice of any change in this policy.

The Fund concentrates its investments in securities of issuers located in the State of Ohio and is non-diversified under the Investment Company Act of 1940, as amended (the “1940 Act”).  The Fund invests primarily in Ohio municipal obligations rated within the three highest rating categories.  The Fund may also purchase Ohio municipal obligations and other securities rated within the four highest rating categories.  If a security's rating is reduced below the four highest rating categories, the security will be sold.  A security may also be sold due to changes in market conditions or Fort Washington Investment Advisors, Inc.'s (“Fort Washington” or “Sub-Advisor”) outlook.  The Fund may purchase unrated obligations that the sub-advisor determines to be of comparable quality.  The Fund will seek to maintain an average weighted maturity of more than 10 years, but may reduce its average weighted maturity to 10 years or below if warranted by market conditions.

The Fund may invest more than 25% of its assets in municipal obligations within a particular segment of the bond market (such as housing agency bonds or airport bonds).  The Fund may also invest more than 25% of its assets in private activity bonds and industrial development bonds which may be backed only by nongovernmental entities.  Under normal circumstances, the Fund will limit its investment in securities whose income is subject to the alternative minimum tax to less than 20% of its assets.  The Fund will not invest more than 25% of its assets in securities backed by nongovernmental entities that are in the same industry.

The Fund has a fundamental investment policy that under normal circumstances at least 80% of the income it distributes will be exempt from federal income tax, including the alternative minimum tax, and Ohio personal income tax. This fundamental policy may not be changed without the approval of the Fund's shareholders.

Risk, Heading

rr_RiskHeading

The Principal Risks

Risk, Narrative

rr_RiskNarrativeTextBlock

The Fund's share price will fluctuate.  You could lose money on your investment in the Fund and the Fund could return less than other investments.  The Fund is subject to the principal risks summarized below.

Credit Risk: The 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:  As interest rates rise, the value of fixed-income securities the Fund owns will be likely to decrease. 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 of the expected life, taking into account any prepayment or call features of the security, of a fixed-income security that is used to determine the price sensitivity of the security for a given change in interest rates. Specifically, duration is the approximate change in the value of a fixed-income security that will result from a 1% change in interest rates, and generally is stated in years. Maturity, on the other hand, is the date on which a fixed-income security becomes due for payment of principal.

Investment-Grade Debt Securities Risk:  Investment-grade debt securities may be downgraded by a Nationally Recognized Statistical Rating Organization (“NRSRO”) to below investment-grade status, which would increase the risk of holding these securities, or a rating may become stale in that it fails to reflect changes to an issuer's financial condition.  Investment-grade debt securities rated in the lowest rating category by an NRSRO involve a higher degree of risk than fixed-income securities in the higher-rating categories.  While such securities are considered investment-grade quality and are deemed to have adequate capacity for payment of principal and interest, such securities lack outstanding investment characteristics and have speculative characteristics as well.  For example, changes in economic conditions or other circumstances are more likely to lead to a weakened capacity to make principal and interest payments than is the case with higher-grade securities.

Management Risk:  The Advisor engages one or more sub-advisors to make investment decisions for a portion or all of the Fund's portfolio.  There is a risk that the Advisor may be unable to identify and retain sub-advisors who achieve superior investment returns relative to other similar sub-advisors.  The value of your investment may decrease if the sub-advisor's judgment about the attractiveness, value or market trends affecting a particular security, issuer, industry or sector or about market movements is incorrect.

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, the ongoing issues facing 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.

Non-Diversification Risk: The Fund is non-diversified, which means that it may invest a greater percentage of its assets than diversified mutual funds in the securities of a limited number of issuers.  The use of a non-diversified investment strategy may increase the volatility of the Fund's investment performance, as the Fund may be more susceptible to risks associated with a single economic, political or regulatory event than a diversified fund.

Prepayment Risk: Prepayment risk is the risk that a debt security may be paid off and proceeds invested earlier than anticipated. Prepayment risk is more prevalent during periods of falling interest rates.

Sector Focus Risk:  A fund that focuses its investments in the securities of a particular bond market sector (e.g., housing agency bonds or airport bonds) is subject to the risk that adverse circumstances will have a greater impact on the fund than a fund that does not focus its investments in a particular sector.  It is possible that economic, business, or political developments or other changes affecting one security in the area of focus will affect other securities in that area of focus in the same manner, thereby increasing the risk of such investments.

State Risk:  Political and economic conditions in the state of Ohio may impact the value of Ohio municipal obligations.  The Fund may lose value due to decreased economic growth, increased unemployment and decreased tax revenue in the state of Ohio.

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the FDIC or any other government agency.  As with any mutual fund, there is no guarantee that the Fund will achieve its investment goal.  You can find more information about the Fund's investments and risks under the “Investment Strategies and Risks” section in the Fund's prospectus.

You could lose money on your investment in the Fund and the Fund could return less than other investments.

Risk, Nondiversified Status

rr_RiskNondiversifiedStatus

The Fund is non-diversified, which means that it may invest a greater percentage of its assets than diversified mutual funds in the securities of a limited number of issuers. The use of a non-diversified investment strategy may increase the volatility of the Fund’s investment performance, as the Fund may be more susceptible to risks associated with a single economic, political or regulatory event than a diversified fund.

Touchstone Tax-Free Money Market Fund (Prospectus Summary) | Touchstone Tax-Free Money Market Fund

TOUCHSTONE TAX-FREE MONEY MARKET FUND SUMMARY

The Fund's Investment Goal

The Touchstone Tax-Free Money Market Fund (the “Fund”) seeks the highest level of interest income exempt from federal income tax, consistent with the protection of capital.  The Fund is a money market fund, which seeks to maintain a constant share price of $1.00 per share.

The Fund's Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund:

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees Touchstone Tax-Free Money Market Fund (USD $)	Tax-Free Money Market Fund Class A	Tax-Free Money Market Fund Class S
Wire Redemption Fee	15	15

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

Annual Fund Operating Expenses Touchstone Tax-Free Money Market Fund		Tax-Free Money Market Fund Class A	Tax-Free Money Market Fund Class S
Management Fees		0.50%	0.50%
Distribution (12b-1) Fees	[1]	0.25%	0.35%

Total Annual Fund Operating Expenses		1.18%	1.27%
Fee Waiver or Expense Reimbursement	[2][3]	(0.29%)	(0.37%)
Total Annual Fund Operating Expenses After Fee Waiver or Expense Reimbursement		0.89%	0.90%

Example.

This example is intended 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 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 (reflecting any contractual fee waivers).  Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example Touchstone Tax-Free Money Market Fund (USD $)	Tax-Free Money Market Fund Class A	Tax-Free Money Market Fund Class S
Expense Example, With Redemption, 1 Year	91	92
Expense Example, With Redemption, 3 Years	346	366
Expense Example, With Redemption, 5 Years	621	661
Expense Example, With Redemption, 10 Years	1,406	1,501

The Fund's Principal Investment Strategies

The Fund invests primarily in high-quality, short-term municipal obligations that pay interest that is exempt from federal income tax.  High-quality, short-term municipal obligations are obligations rated within the two highest rating categories, with maturities of 397 days or less and that are rated in one of the two highest short-term rating categories or determined by the investment advisor to be of comparable quality.

The Fund has a fundamental investment policy that under normal circumstances it will invest its assets so that at least 80% of the income it distributes will be exempt from federal income tax, including the alternative minimum tax.  This fundamental policy may not be changed without the approval of the Fund's shareholders.

The Fund may invest more than 25% of its assets in municipal obligations within a particular segment of the bond market (such as housing agency bonds or airport bonds).  The Fund may also invest more than 25% of its assets in private activity bonds and industrial development bonds, which may be backed only by nongovernmental entities.  Under normal circumstances, the Fund will limit its investment in securities whose income is subject to the alternative minimum tax to less than 20% of its assets.  The Fund will not invest more than 25% of its assets in securities backed by nongovernmental entities that are in the same industry.

The Fund may invest in the following types of municipal obligations:

·Tax-exempt bonds, including general obligation bonds, revenue bonds and industrial development bonds.

·Tax-exempt notes.

·Tax-exempt commercial paper.

·Floating and variable rate municipal obligations.

·When-issued obligations.

·Obligations with puts attached.

The Fund maintains a dollar-weighted average portfolio maturity of 60 days or less, dollar-weighted average life of 120 days or less, and purchases only United States dollar-denominated securities with maturities of 397 days or less.  The Fund will hold at least 30% of its total assets in “Weekly Liquid Assets” which includes cash (including demand deposits), direct obligations of the U.S. government, agency discount notes with remaining maturities of 60 days or less, and securities (including repurchase agreements) that will mature or are subject to a demand feature that is exercisable and payable within 5 business days.  The Fund is also subject to the quality and diversification requirements of Rule 2a-7 under the Investment Company Act of 1940, as amended, that are designed to help it maintain a constant share price of $1.00 per share.

The Principal Risks

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the FDIC or any other government agency.  Although the Fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the Fund.  There is no guarantee that the Fund will be able to avoid a negative yield.  The Fund is subject to the “Principal Risks” summarized below.

Credit Risk:  The 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:  As interest rates rise, the value of fixed income securities the Fund owns will be likely to decrease. 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 of the expected life, taking into account any prepayment or call features of the security, of a fixed income security that is used to determine the price sensitivity of the security for a given change in interest rates. Specifically, duration is the change in the value of a fixed income security that will result from a 1% change in interest rates, and generally is stated in years. Maturity, on the other hand, is the date on which a fixed income security becomes due for payment of principal.

Management Risk:  The Advisor engages one or more sub-advisors to make investment decisions for a portion or all of the Fund's portfolio. There is a risk that the Advisor may be unable to identify and retain sub-advisors who achieve superior investment returns relative to other similar sub-advisors.  The value of your investment may decrease if the sub-advisor incorrectly judges market movements or the attractiveness or value or market trends affecting a particular security, issuer, industry or sector.

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, the ongoing issues facing 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.  This could cause the value of the Fund's shares to decrease to a price less than $1.00 per share.

Sector Focus Risk:  The Fund may focus its investments in certain industries within certain sectors.  A fund that focuses its investments in the securities of a particular market sector is subject to the risk that adverse circumstances will have a greater impact on the fund than a fund that does not focus its investments in a particular sector.  It is possible that economic, business or political developments or other changes affecting one security in the area of focus will affect other securities in that area of focus in the same manner, thereby increasing the risk of such investments.

See the discussion entitled 'Expense Limitation' under the section entitled 'The Investment Advisor' in the Fund's Statement of Additional Information for more information.

[3] The fee waivers do not correlate to the ratio of net expenses to average net assets shown in the annual report due to an additional voluntary fee waiver. During the last fiscal year, Touchstone Advisors voluntarily waived additional fees or reimbursed certain Fund expenses. Due to the voluntary fee waivers, the Fund's actual ratio of net expenses to average net assets was 0.30% and 0.30% for Class A shares and Class S shares, respectively.

The Fund's Principal Investment Strategies

The Fund invests primarily in high-quality, short-term Ohio municipal obligations issued by the State of Ohio, its agencies and municipalities, that pay interest that is exempt from both federal income tax and Ohio personal income tax.  High-quality, short-term Ohio municipal obligations are obligations with maturities of 397 days or less and that are rated in one of the two highest short-term rating categories or determined by the investment advisor to be of comparable quality.  Under normal circumstances, at least 80% of the Fund's assets will be invested in Ohio municipal obligations.  This is a non-fundamental investment policy and the Fund will provide shareholders with at least 60-days prior notice of any change in this policy.

The Fund has a fundamental investment policy that under normal circumstances it will invest at least 80% of its assets in short-term municipal obligations that pay interest that is exempt from federal income tax, including the alternative minimum tax, and Ohio personal income tax.  This fundamental policy may not be changed without the approval of the Fund's shareholders.

The Fund concentrates its investments in securities of issuers located in the State of Ohio and is non-diversified under the Investment Company Act, as amended (the “1940 Act”). The Fund may invest more than 25% of its assets in municipal obligations within a particular segment of the bond market (such as housing agency bonds or airport bonds).  The Fund may also invest more than 25% of its assets in private activity bonds and industrial development bonds, which may be backed only by nongovernmental entities.  Under normal circumstances, the Fund will limit its investment in securities whose income is subject to the alternative minimum tax to less than 20% of its assets.  The Fund will not invest more than 25% of its assets in securities backed by nongovernmental entities that are in the same industry.  The Fund may invest in the following types of Ohio municipal obligations and other municipal obligations:

·Tax-exempt bonds, including general obligation bonds, revenue bonds and industrial development bonds

·Tax-exempt notes

·Tax-exempt commercial paper

·Floating and variable rate municipal obligations

·When-issued obligations

·Obligations with puts attached

The Fund maintains a dollar-weighted average portfolio maturity of 60 days or less, a dollar-weighted average life of 120 days or less, and purchases only United States dollar-denominated securities with maturities of 397 days or less.  The Fund will hold at least 30% of its total assets in “Weekly Liquid Assets”, which includes cash (including demand deposits), direct obligations of the U.S. government, agency discount notes with remaining maturities of 60 days or less, and securities (including repurchase agreements) that will mature or are subject to a demand feature that is exercisable and payable within 5 business days.  The Fund is also subject to quality and diversification requirements of Rule 2a-7 under the 1940 Act that are designed to help it maintain a constant share price of $1.00 per share.

The Principal Risks

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the FDIC or any other government agency.  Although the Fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the Fund.  There is no guarantee that the Fund will be able to avoid a negative yield.  The Fund is subject to the Principal Risks summarized below.

Credit Risk:  The 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:  As interest rates rise, the value of fixed-income securities the Fund owns will be likely to decrease. 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 of the expected life, taking into account any prepayment or call features of the security, of a fixed-income security that is used to determine the price sensitivity of the security for a given change in interest rates. Specifically, duration is the change in the value of a fixed-income security that will result from a 1% change in interest rates, and generally is stated in years. Maturity, on the other hand, is the date on which a fixed-income security becomes due for payment of principal.

Management Risk: The Advisor engages one or more sub-advisors to make investment decisions for a portion or all of the Fund's portfolio.  There is a risk that the Advisor may be unable to identify and retain sub-advisors who achieve superior investment returns relative to other similar sub-advisors.  The value of your investment may decrease if the sub- advisor's judgment about the attractiveness, value or market trends affecting a particular security, issuer, industry or sector or about market movements is incorrect.

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, the ongoing issues facing 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.  This could cause the value of the Fund's shares to decrease to a price less than $1.00 per share.

Non-Diversification Risk:  The Fund is non-diversified, which means that it may invest a greater percentage of its assets than diversified mutual funds in the securities of a limited number of issuers.  The use of a non-diversified investment strategy may increase the volatility of the Fund's investment performance, as the Fund may be more susceptible to risks associated with a single economic, political or regulatory event than a diversified fund.

Sector Focus Risk:  A fund that focuses its investments in the securities of a particular bond market sector (e.g., housing agency bonds or airport bonds) is subject to the risk that adverse circumstances will have a greater impact on the fund than a fund that does not focus its investments in a particular sector.  It is possible that economic, business or political developments or other changes affecting one security in the area of focus will affect other securities in that area of focus in the same manner, thereby increasing the risk of such investments.

State Risk:  Political and economic conditions in the state of Ohio may impact the value of Ohio municipal obligations.  The Fund's yield may decrease due to decreased economic growth, increased unemployment and decreased tax revenue in the state of Ohio.

The Principal Risks

Risk, Narrative

rr_RiskNarrativeTextBlock

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the FDIC or any other government agency.  Although the Fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the Fund.  There is no guarantee that the Fund will be able to avoid a negative yield.  The Fund is subject to the Principal Risks summarized below.

Credit Risk:  The 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:  As interest rates rise, the value of fixed-income securities the Fund owns will be likely to decrease. 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 of the expected life, taking into account any prepayment or call features of the security, of a fixed-income security that is used to determine the price sensitivity of the security for a given change in interest rates. Specifically, duration is the change in the value of a fixed-income security that will result from a 1% change in interest rates, and generally is stated in years. Maturity, on the other hand, is the date on which a fixed-income security becomes due for payment of principal.

Management Risk: The Advisor engages one or more sub-advisors to make investment decisions for a portion or all of the Fund's portfolio.  There is a risk that the Advisor may be unable to identify and retain sub-advisors who achieve superior investment returns relative to other similar sub-advisors.  The value of your investment may decrease if the sub- advisor's judgment about the attractiveness, value or market trends affecting a particular security, issuer, industry or sector or about market movements is incorrect.

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, the ongoing issues facing 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.  This could cause the value of the Fund's shares to decrease to a price less than $1.00 per share.

Non-Diversification Risk:  The Fund is non-diversified, which means that it may invest a greater percentage of its assets than diversified mutual funds in the securities of a limited number of issuers.  The use of a non-diversified investment strategy may increase the volatility of the Fund's investment performance, as the Fund may be more susceptible to risks associated with a single economic, political or regulatory event than a diversified fund.

Sector Focus Risk:  A fund that focuses its investments in the securities of a particular bond market sector (e.g., housing agency bonds or airport bonds) is subject to the risk that adverse circumstances will have a greater impact on the fund than a fund that does not focus its investments in a particular sector.  It is possible that economic, business or political developments or other changes affecting one security in the area of focus will affect other securities in that area of focus in the same manner, thereby increasing the risk of such investments.

State Risk:  Political and economic conditions in the state of Ohio may impact the value of Ohio municipal obligations.  The Fund's yield may decrease due to decreased economic growth, increased unemployment and decreased tax revenue in the state of Ohio.

Risk, Nondiversified Status

rr_RiskNondiversifiedStatus

The Fund is non-diversified, which means that it may invest a greater percentage of its assets than diversified mutual funds in the securities of a limited number of issuers. The use of a non-diversified investment strategy may increase the volatility of the Fund’s investment performance, as the Fund may be more susceptible to risks associated with a single economic, political or regulatory event than a diversified fund.

[1] Touchstone Advisors, Inc. and the Trust have entered into an expense limitation agreement whereby Touchstone Advisors has contractually agreed to waive a portion of its fees or reimburse certain Fund expenses (excluding dividend expenses relating to short sales, interest, taxes, brokerage commissions, other expenditures which are capitalized in accordance with generally accepted accounting principles, the cost of 'Acquired Fund Fees and Expenses,' if any, and other extraordinary expenses not incurred in the ordinary course of business) in order to limit annual fund operating expenses to 0.75% and 0.50% for Class A and Institutional Class shares, respectively. This expense limitation will remain in effect until at least October 29, 2014, but can be terminated by a vote of the Board of Trustees of the Fund (the 'Board') if they deem the termination to be beneficial to the Fund's shareholders. Touchstone Advisors is entitled to recoup, subject to approval by the Board, such amounts reduced or reimbursed for a period of up to three years from the year in which Touchstone Advisors reduced its compensation or assumed expenses for the Fund. No recoupment will occur unless the Fund's expenses are below the expense limitation. See the discussion entitled 'Expense Limitation' under the section entitled 'The Investment Advisor and Sub-Advisor' in the Fund's Statement of Additional Information for more information.

[2] The fee waivers do not correlate to the ratio of net expenses to average net assets shown in the annual report due to an additional voluntary fee waiver. During the last fiscal year, Touchstone Advisors voluntarily waived additional fees or reimbursed certain Fund expenses. Due to the voluntary fee waivers, the Fund's actual ratio of net expenses to average net assets was 0.24% and 0.24% for Class A and Institutional Class shares, respectively.
