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 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 portfolio turnover rate of the Fund was 88.66% of the average value of its portfolio.

Expense Example [Heading]	rr_ExpenseExampleHeading	Example.
Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	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 the contractual fee waiver). Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy [Heading]	rr_StrategyHeading	The Fund's Principal Investment Strategies
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund is a "fund-of-funds," which seeks to achieve its investment goal by primarily investing in a diversified portfolio of affiliated underlying equity and fixed-income funds (although a portion of its assets may be invested in cash, cash equivalents, or in money market funds). These affiliated underlying funds, in turn, invest in a variety of U.S. and foreign equity and fixed-income securities. The following table details, under normal circumstances, how the Fund expects to allocate its assets among equity and fixed-income funds. Equity Fund Allocation   Fixed-Income Fund Allocation         20-40%                      60-80% The Fund's sub-advisor, Ibbotson Associates, Inc. ("Ibbotson"), seeks to develop an optimal model allocation among underlying funds using an analysis that looks at forecasted returns, standard deviations in historical returns, and the correlation of the performance of different market sectors. The Fund may invest 0-45% of its assets in any individual underlying fund. Ibbotson and the Fund's investment advisor agree from time to time upon the universe of underlying funds that Ibbotson may consider when making allocation decisions. Ibbotson's analysis in selecting and weighting the underlying funds from that universe includes historical returns-based style analysis, holdings-based style analysis, manager interviews, relative and absolute performance, including correlations with other underlying funds as well as corresponding benchmarks, and historical volatility (the variability of returns from one period to the next). When considering equity funds, Ibbotson focuses on the underlying funds' foreign and domestic exposure, market capitalization ranges, use of derivative strategies, and investment style (growth vs. value). When considering fixed-income funds, Ibbotson's primary focus is the overall level of risk in the type of fixed-income securities in which the underlying funds invest and on maximizing current income and long-term capital growth. Ibbotson, subject to approval by the Fund's investment advisor, may change the Fund's target allocation to each asset class, the underlying funds in each asset class (including adding or deleting underlying funds), or target allocations to each underlying fund without prior approval from or notice to shareholders. Decisions to sell shares of the underlying funds are made to adjust an underlying fund's target allocation based on Ibbotson's view of the Fund's characteristics and other allocation criteria, for cash flow resulting from redemptions, or as a result of periodic rebalancing of the Fund's holdings. For information on the underlying funds, please see the section entitled "Additional Information Regarding the Underlying Funds" under "Investment Strategies and Risks" in the Fund's Prospectus.
Risk [Heading]	rr_RiskHeading	The Principal Risks
Risk Narrative [Text Block]	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. Risks of Fund of Funds Structure: The value of an investment in the Fund is based on the performance of the underlying funds in which it invests and the allocation of its assets among those funds. The underlying funds may change their investment goals, policies or practices and there can be no assurance that the underlying funds will achieve their respective investment goals. Because the Fund invests in mutual funds, it bears a proportionate share of the expenses charged by the underlying funds in which it invests. The principal risks of an investment in the Fund include the principal risks of investing in the underlying funds. The Fund is exposed to the risks of the underlying funds in which it invests in direct proportion to the amount of assets the Fund allocates to each underlying fund. To the extent that the Fund invests more of its assets in one underlying fund than another, the Fund will have greater exposure to the risks of that underlying fund. One underlying fund may buy the same security that another underlying fund is selling. You would indirectly bear the costs of both trades. In addition, you may receive taxable gains from portfolio transactions by the underlying funds, as well as taxable gains from the Fund's transactions in shares of the underlying funds. The Fund's ability to achieve its investment goal depends upon Ibbotson's skill in selecting the best mix of underlying funds. There is the risk that Ibbotson's evaluations and assumptions regarding the underlying funds may be incorrect in view of actual market conditions. The underlying funds are expected to be subject to the following principal risks. o Underlying Equity Fund Risks: These underlying funds are subject to the risk that stock prices will fall (or rise with respect to short positions) over short or extended periods of time.  Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. Conversely, the risk of price increases with respect to securities sold short will also cause a decline in the value of the underlying fund's shares. The prices of securities issued by these companies may decline in response to such developments, which could result in a decline in the value of the underlying fund's shares. The risks of investing in underlying equity funds include risks specific to their investment strategies, such as investment style risk and capitalization risk.. o Underlying Fixed Income Funds Risks: The prices of an underlying fund's fixed income securities respond to economic developments, particularly interest rate changes, as well as to perceptions about the creditworthiness of individual issuers, including governments. Other principal risks include call risk and high-yield debt ("junk bond") risk. Call risk refers to situations when an issuer prepays (or "calls") a debt obligation prior to maturity and an underlying fund holding that debt must invest the resulting proceeds at lower interest rates. High-yield debt risk refers to non-investment grade debt obligations ("junk bonds") that carry a higher risk of default by the issuer, and are generally considered speculative and less liquid than investment-grade debt obligations. o Derivatives Risk: Certain of the underlying funds may invest in derivatives, such as futures, options or swap contracts, to pursue their investment goals. The use of such derivatives may expose an underlying fund to additional risks that it would not be subject to if it invested directly in the securities underlying those derivatives, including the risk of counterparty default. These additional risks could cause an underlying fund to experience losses to which it would otherwise not be subject. An underlying fund may use derivatives to gain exposure to (or hedge exposure against) a particular market, currency or instrument, to adjust the underlying fund's duration or attempt to manage interest rate risk, and for certain other purposes consistent with its investment strategy. An underlying fund may not fully benefit from or may lose money on derivative investments. o Foreign Securities Risk: Certain underlying funds may invest in foreign securities, which pose risks in addition to those posed by domestic securities because political and economic events unique in a country or region will affect those markets and their issuers. These events will not necessarily affect the U.S. economy or similar issuers located in the United States. In addition, investments in foreign securities are generally denominated in foreign currency. Foreign markets may be less liquid and more volatile than U.S. markets and offer less protection to investors. Emerging markets may be more likely to experience political turmoil or rapid changes in market or economic conditions than more developed countries. In addition, the financial stability of issuers (including governments) in emerging market countries may be more precarious than in other countries. Management Risk: 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. Merger Arbitrage Risk: Investments in companies that are expected to be, or already are, the subject of a publicly announced transaction carry the risk that the proposed or expected transaction may not be completed or may be completed on less favorable terms than originally expected, which may lower performance. 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 of the Fund's Prospectus.

[1] The Total Annual Fund Operating Expenses do not correlate to the ratio of expenses to average net assets that are included in the Fund's Annual Report dated July 31, 2012, which reflects the operating expenses of the Fund and does not include Acquired Fund Fees and Expenses.

[2] Expenses shown above have been restated to reflect a change in the Fund's contractual fee waiver, and will differ from the expenses shown in the Fund's Annual Report.

[3] Effective September 10, 2012, Touchstone Advisors 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 in order to limit annual fund operating expenses to 0.33%, 1.08%, 0.08% and 0.08% for Class A shares, Class C shares, Class Y shares, and Institutional shares, respectively. This expense limitation will remain in effect until September 10, 2013 but can be terminated by a vote of the Board of Trustees of the Fund if they deem the termination to be beneficial to the Fund shareholders. Following the expiration of the contractual fee waiver above, Touchstone Advisors has contractually agreed to waive a portion of its fees and/or reimburse certain Fund expenses in order to limit annual fund operating expenses to 0.41%, 1.16%, 0.16% and 0.16% for Class A shares, Class C shares, Class Y shares, and Institutional shares, respectively. This expense limitation will remain in effect until at least April 16, 2014 but can be terminated by a vote of the Board of Trustees of the Fund if they deem the termination to be beneficial to the Fund shareholders. Touchstone Advisors is entitled to recoup, subject to approval by the Board of Trustees of the Fund, such amounts reduced or reimbursed for a period of up to three (3) 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 "Contractual Fee Waiver Agreement" under the section entitled "The Funds' Management" in the Fund's Prospectus for more information. The fee table reflects only expense limitations in effect until April 16, 2014.

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 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 portfolio turnover rate of the Fund was 76.54% of the average value of its portfolio.

Expense Example [Heading]	rr_ExpenseExampleHeading	Example.
Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	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 the contractual fee waiver). Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy [Heading]	rr_StrategyHeading	The Fund's Principal Investment Strategies
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund is a "fund-of-funds," which seeks to achieve its investment goal by primarily investing in a diversified portfolio of affiliated underlying equity and fixed-income funds (although a portion of its assets may be invested in cash, cash equivalents, or in money market funds). These affiliated underlying funds, in turn, invest in a variety of U.S. and foreign equity and fixed-income securities. The following table details, under normal circumstances, how the Fund expects to allocate its assets among equity and fixed-income funds.               Equity Fund Allocation   Fixed-Income Fund Allocation                      90-100%                      0-10% The Fund's sub-advisor, Ibbotson Associates, Inc. ("Ibbotson"), seeks to develop an optimal model allocation among underlying funds using an analysis that looks at forecasted returns, standard deviations in historical returns, and the correlation of the performance of different market sectors. The Fund may invest 0-45% of its assets in any individual underlying fund. Ibbotson and the Fund's investment advisor agree from time to time upon the universe of underlying funds that Ibbotson may consider when making allocation decisions. Ibbotson's analysis in selecting and weighting the underlying funds from that universe includes historical returns-based style analysis, holdings-based style analysis, manager interviews, relative and absolute performance, including correlations with other underlying funds as well as corresponding benchmarks, and historical volatility (the variability of returns from one period to the next). When considering equity funds, Ibbotson focuses on the underlying funds' foreign and domestic exposure, market capitalization ranges, use of derivative strategies, and investment style (growth vs. value). When considering fixed-income funds, Ibbotson's primary focus is the overall level of risk in the type of fixed income securities in which the underlying funds invest and on maximizing current income and long-term capital growth. Ibbotson, subject to approval by the Fund's investment advisor, may change the Fund's target allocation to each asset class, the underlying funds in each asset class (including adding or deleting underlying funds), or target allocations to each underlying fund without prior approval from or notice to shareholders. Decisions to sell shares of the underlying funds are made to adjust an underlying fund's target allocation based on Ibbotson's view of the Fund's characteristics and other allocation criteria, for cash flow resulting from redemptions, or as a result of periodic rebalancing of the Fund's holdings. For information on the underlying funds, please see the section entitled "Additional Information Regarding the Underlying Funds" under "Investment Strategies and Risks" in the Fund's Prospectus.
Risk [Heading]	rr_RiskHeading	The Principal Risks
Risk Narrative [Text Block]	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. Risks of Fund of Funds Structure: The value of an investment in the Fund is based on the performance of the underlying funds in which it invests and the allocation of its assets among those funds. The underlying funds may change their investment goals, policies or practices and there can be no assurance that the underlying funds will achieve their respective investment goals. Because the Fund invests in mutual funds, it bears a proportionate share of the expenses charged by the underlying funds in which it invests. The principal risks of an investment in the Fund include the principal risks of investing in the underlying funds. The Fund is exposed to the risks of the underlying funds in which it invests in direct proportion to the amount of assets the Fund allocates to each underlying fund. To the extent that the Fund invests more of its assets in one underlying fund than another, the Fund will have greater exposure to the risks of that underlying fund. One underlying fund may buy the same security that another underlying fund is selling. You would indirectly bear the costs of both trades. In addition, you may receive taxable gains from portfolio transactions by the underlying funds, as well as taxable gains from the Fund's transactions in shares of the underlying funds. The Fund's ability to achieve its investment goal depends upon Ibbotson's skill in selecting the best mix of underlying funds. There is the risk that Ibbotson's evaluations and assumptions regarding the underlying funds may be incorrect in view of actual market conditions. The underlying funds are expected to be subject to the following principal risks. o Underlying Equity Fund Risks: These underlying funds are subject to the risk that stock prices will fall (or rise with respect to short positions) over short or extended periods of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. Conversely, the risk of price increases with respect to securities sold short will also cause a decline in the value of the underlying fund's shares. The prices of securities issued by these companies may decline in response to such developments, which could result in a decline in the value of the underlying fund's shares. The risks of investing in underlying equity funds include risks specific to their investment strategies, such as investment style risk and capitalization risk. o Underlying Fixed Income Funds Risks: The prices of an underlying fund's fixed income securities respond to economic developments, particularly interest rate changes, as well as to perceptions about the creditworthiness of individual issuers, including governments. Other principal risks include call risk and high-yield debt ("junk bond") risk. Call risk refers to situations when an issuer prepays (or "calls") a debt obligation prior to maturity and an underlying fund holding that debt  must invest the resulting proceeds at lower interest rates. High-yield debt risk refers to non-investment grade debt obligations ("junk bonds") that carry a higher risk of default by the issuer, resulting in losses to the underlying fund, and are generally considered speculative and less liquid than investment-grade debt obligations. o Derivatives Risk: Certain of the underlying funds may invest in derivatives, such as futures, options or swap contracts, to pursue their investment goals. The use of such derivatives may expose an underlying fund to additional risks that it would not be subject to if it invested directly in the securities underlying those derivatives, including the risk of counterparty default. These additional risks could cause an underlying fund to experience losses to which it would otherwise not be subject. An underlying fund may use derivatives to gain exposure to (or hedge exposure against) a particular market, currency or instrument, to adjust the underlying fund's duration or attempt to manage interest rate risk, and for certain other purposes consistent with its investment strategy. An underlying fund may not fully benefit from or may lose money on derivative investments. o Foreign Securities Risk: Certain underlying funds may invest in foreign securities, which pose risks in addition to those posed by domestic securities because political and economic events unique in a country or region will affect those markets and their issuers. These events will not necessarily affect the U.S. economy or similar issuers located in the United States. In addition, investments in foreign securities are generally denominated in foreign currency. Foreign markets may be less liquid and more volatile than U.S. markets and offer less protection to investors. Emerging markets may be more likely to experience political turmoil or rapid changes in market or economic conditions than more developed countries. In addition, the financial stability of issuers (including governments) in emerging market countries may be more precarious than in other countries. o Management Risk:  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. o Merger Arbitrage Risk:  Investments in companies that are expected to be, or already are, the subject of a publicly announced transaction carry the risk that the proposed or expected transaction may not be completed or may be completed on less favorable terms than originally expected, which may lower performance. 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 of the Fund's Prospectus.

[1] The Total Annual Fund Operating Expenses do not correlate to the ratio of expenses to average net assets that are included in the Fund's Annual Report dated July 31, 2012, which reflects the operating expenses of the Fund and does not include Acquired Fund Fees and Expenses.

[2] Expenses shown above have been restated to reflect a change in the Fund's contractual fee waiver, and will differ from the expenses shown in the Fund's Annual Report.

[3] Effective September 10, 2012, Touchstone Advisors 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 in order to limit annual fund operating expenses to 0.33%, 1.08%, 0.08%, and 0.08% for Class A shares, Class C shares, Class Y shares, and Institutional shares, respectively. This expense limitation will remain in effect until September 10, 2013, but can be terminated by a vote of the Board of Trustees of the Fund if they deem the termination to be beneficial to the Fund shareholders. Following the expiration of the contractual fee waiver above, Touchstone Advisors has contractually agreed to waive a portion of its fees and/or reimburse certain Fund expenses in order to limit annual fund operating expenses to 0.41%, 1.16%, 0.16%, and 0.16% for Class A shares, Class C shares, Class Y shares, and Institutional shares, respectively. This expense limitation will remain in effect until at least April 16, 2014 but can be terminated by a vote of the Board of Trustees of the Fund if they deem the termination to be beneficial to the Fund shareholders. Touchstone Advisors is entitled to recoup, subject to approval by the Board of Trustees of the Fund, such amounts reduced or reimbursed for a period of up to three (3) 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 "Contractual Fee Waiver Agreement" under the section entitled "The Funds' Management" in the Fund's Prospectus for more information. The fee table reflects only expense limitations in effect until April 16, 2014.

Strategy [Heading]	rr_StrategyHeading	The Fund's Principal Investment Strategies
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund normally invests at least 80% of its assets in equity of non-U.S. issuers. This is a non-fundamental investment policy that can be changed by the Fund upon 60 days' prior notice to shareholders.  The Fund primarily invests its assets in common stock of issuers located in developed markets. Generally, the Fund limits its investments in any country to 25% or less of its total assets, except that the Fund may invest more than 25% of its assets in issuers organized in Japan or the United Kingdom or in securities quoted or denominated in the Japanese yen, the British pound, or the euro. The Fund's sub-advisor, Acadian Asset Management LLC ("Acadian"), uses stock factors in an effort to predict how well each security will perform relative to its region/industry peer group and applies separate models to forecast peer group returns. The two forecasts are then combined to determine a world-relative return forecast for each stock in the allowable universe, and Acadian uses a sophisticated portfolio optimization system to trade off the expected return of the stocks with such considerations as the client's benchmark index, desired level of risk, transaction cost estimates, available liquidity, and other requirements. Acadian considers selling a security whose forecast has deteriorated and may adjust its buy and sell decisions based on shifts in the risk characteristics of a stock relative to other potential substitutes, the overall portfolio and the benchmark.
Risk [Heading]	rr_RiskHeading	The Principal Risks
Risk Narrative [Text Block]	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. Equity Securities Risk: The Fund is subject to the risk that stock prices will fall over short or extended periods of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by these companies may decline in response to such developments, which could result in a decline in the value of the Fund's shares. Management Risk: 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. Foreign Securities Risk: Investing in foreign securities poses additional risks since political and economic events unique in a country or region will affect those markets and their issuers. Because the Fund may invest a large portion of its assets in securities of companies located in Japan and the United Kingdom, the Fund's performance may be impacted by social, political, and economic conditions within Japan and the United Kingdom. These events will not necessarily affect the U.S. economy or similar issuers located in the United States. In addition, investments in foreign securities are generally denominated in foreign currency. As a result, changes in the value of those currencies compared to the U.S. dollar may affect (positively or negatively) the value of the Fund's investments. These currency movements may happen separately from, or in response to, events that do not otherwise affect the value of the security in the issuer's home country. There is a risk that foreign securities may not be subject to accounting standards or governmental supervision comparable to U.S. companies and that less public information about their operations may exist. There is risk associated with the clearance and settlement procedures in non-U.S. markets, which may be unable to keep pace with the volume of securities transactions and may cause delays. Foreign markets may be less liquid and more volatile than U.S. markets and offer less protection to investors. Over-the-counter securities may also be less liquid than exchange-traded securities. 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 of the Fund's Prospectus.

[1] Class C shares commenced operations on April 16, 2012. Class C shares would have had substantially similar annual returns because the shares are invested in the same portfolio. Annual returns would differ only to the extent that the Classes have different expenses.

[2] The Total Annual Fund Operating Expenses do not correlate to the ratio of expenses to average net assets that are included in the Fund's Annual Report dated July 31, 2012, which reflects the operating expenses of the Fund and does not include Acquired Fund Fees and Expenses.

[3] Touchstone Advisors 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 in order to limit annual fund operating expenses to 1.39%, 2.14%, 1.14%, and 0.99%, for Class A shares, Class C shares, Class Y shares, and Institutional shares, respectively. This expense limitation will remain in effect until at least April 16, 2014, but can be terminated by a vote of the Board of Trustees of the Fund if they deem the termination to be beneficial to the Fund shareholders. Touchstone Advisors is entitled to recoup, subject to approval by the Board of Trustees of the Fund, such amounts reduced or reimbursed for a period of up to three (3) 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 "Contractual Fee Waiver Agreement" under the section entitled "The Funds' Management" in the Fund's Prospectus for more information.

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 the contractual
fee waiver). Although your actual costs may be higher or lower, based on these
assumptions your costs would be:

Assuming Redemption at End of Period

Expense Example Touchstone Growth Allocation Fund (USD $)	Class A	Class C	Class Y	Institutional
Expense Example, with Redemption, 1 Year	708	317	116	116
Expense Example, with Redemption, 3 Years	1,102	774	581	1,441
Expense Example, with Redemption, 5 Years	1,569	1,402	1,166	3,125
Expense Example, with Redemption, 10 Years	2,857	3,093	2,758	6,825

Assuming No Redemption

Expense Example, No Redemption (USD $)	Expense Example, No Redemption, 1 Year	Expense Example, No Redemption, 3 Years	Expense Example, No Redemption, 5 Years	Expense Example, No Redemption, 10 Years
Touchstone Growth Allocation Fund Class C	217	774	1,402	3,093

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 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 portfolio turnover rate
of the Fund was 76.54% of the average value of its portfolio.

The Fund's Principal Investment Strategies

The Fund is a "fund-of-funds," which seeks to achieve its investment goal by
primarily investing in a diversified portfolio of affiliated underlying equity
and fixed-income funds (although a portion of its assets may be invested in
cash, cash equivalents, or in money market funds). These affiliated underlying
funds, in turn, invest in a variety of U.S. and foreign equity and fixed-income
securities.

The following table details, under normal circumstances, how the Fund expects to
allocate its assets among equity and fixed-income funds.

              Equity Fund Allocation   Fixed-Income Fund Allocation
                     90-100%                      0-10%

The Fund's sub-advisor, Ibbotson Associates, Inc. ("Ibbotson"), seeks to develop
an optimal model allocation among underlying funds using an analysis that looks
at forecasted returns, standard deviations in historical returns, and the
correlation of the performance of different market sectors. The Fund may invest
0-45% of its assets in any individual underlying fund.

Ibbotson and the Fund's investment advisor agree from time to time upon the
universe of underlying funds that Ibbotson may consider when making allocation
decisions. Ibbotson's analysis in selecting and weighting the underlying funds
from that universe includes historical returns-based style analysis,
holdings-based style analysis, manager interviews, relative and absolute
performance, including correlations with other underlying funds as well as
corresponding benchmarks, and historical volatility (the variability of returns
from one period to the next). When considering equity funds, Ibbotson focuses
on the underlying funds' foreign and domestic exposure, market capitalization
ranges, use of derivative strategies, and investment style (growth vs. value).
When considering fixed-income funds, Ibbotson's primary focus is the overall
level of risk in the type of fixed income securities in which the underlying
funds invest and on maximizing current income and long-term capital growth.

Ibbotson, subject to approval by the Fund's investment advisor, may change the
Fund's target allocation to each asset class, the underlying funds in each asset
class (including adding or deleting underlying funds), or target allocations to
each underlying fund without prior approval from or notice to shareholders.

Decisions to sell shares of the underlying funds are made to adjust an underlying
fund's target allocation based on Ibbotson's view of the Fund's characteristics
and other allocation criteria, for cash flow resulting from redemptions, or as a
result of periodic rebalancing of the Fund's holdings. For information on the
underlying funds, please see the section entitled "Additional Information
Regarding the Underlying Funds" under "Investment Strategies and Risks" in the
Fund's Prospectus.

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.

Risks of Fund of Funds Structure: The value of an investment in the Fund is
based on the performance of the underlying funds in which it invests and the
allocation of its assets among those funds. The underlying funds may change
their investment goals, policies or practices and there can be no assurance that
the underlying funds will achieve their respective investment goals. Because the
Fund invests in mutual funds, it bears a proportionate share of the expenses
charged by the underlying funds in which it invests. The principal risks of an
investment in the Fund include the principal risks of investing in the
underlying funds.

The Fund is exposed to the risks of the underlying funds in which it invests in
direct proportion to the amount of assets the Fund allocates to each underlying
fund. To the extent that the Fund invests more of its assets in one underlying
fund than another, the Fund will have greater exposure to the risks of that
underlying fund. One underlying fund may buy the same security that another
underlying fund is selling. You would indirectly bear the costs of both trades.
In addition, you may receive taxable gains from portfolio transactions by the
underlying funds, as well as taxable gains from the Fund's transactions in
shares of the underlying funds. The Fund's ability to achieve its investment
goal depends upon Ibbotson's skill in selecting the best mix of underlying
funds. There is the risk that Ibbotson's evaluations and assumptions regarding
the underlying funds may be incorrect in view of actual market conditions.

The underlying funds are expected to be subject to the following principal
risks.

o Underlying Equity Fund Risks: These underlying funds are subject to the
risk that stock prices will fall (or rise with respect to short positions)
over short or extended periods of time. Individual companies may report poor
results or be negatively affected by industry and/or economic trends and
developments. Conversely, the risk of price increases with respect to
securities sold short will also cause a decline in the value of the underlying
fund's shares. The prices of securities issued by these companies may decline in
response to such developments, which could result in a decline in the value of
the underlying fund's shares. The risks of investing in underlying equity funds
include risks specific to their investment strategies, such as investment style
risk and capitalization risk.

o Underlying Fixed Income Funds Risks: The prices of an underlying fund's fixed
income securities respond to economic developments, particularly interest rate
changes, as well as to perceptions about the creditworthiness of individual
issuers, including governments. Other principal risks include call risk and
high-yield debt ("junk bond") risk. Call risk refers to situations when an
issuer prepays (or "calls") a debt obligation prior to maturity and an
underlying fund holding that debt  must invest the resulting proceeds at lower
interest rates. High-yield debt risk refers to non-investment grade debt
obligations ("junk bonds") that carry a higher risk of default by the issuer,
resulting in losses to the underlying fund, and are generally considered
speculative and less liquid than investment-grade debt obligations.

o Derivatives Risk: Certain of the underlying funds may invest in derivatives,
such as futures, options or swap contracts, to pursue their investment goals.
The use of such derivatives may expose an underlying fund to additional risks
that it would not be subject to if it invested directly in the securities
underlying those derivatives, including the risk of counterparty default.
These additional risks could cause an underlying fund to experience losses to
which it would otherwise not be subject. An underlying fund may use derivatives
to gain exposure to (or hedge exposure against) a particular market, currency
or instrument, to adjust the underlying fund's duration or attempt to manage
interest rate risk, and for certain other purposes consistent with its
investment strategy. An underlying fund may not fully benefit from or may
lose money on derivative investments.

o Foreign Securities Risk: Certain underlying funds may invest in foreign
securities, which pose risks in addition to those posed by domestic securities
because political and economic events unique in a country or region will affect
those markets and their issuers. These events will not necessarily affect the
U.S. economy or similar issuers located in the United States. In addition,
investments in foreign securities are generally denominated in foreign currency.
Foreign markets may be less liquid and more volatile than U.S. markets and offer
less protection to investors. Emerging markets may be more likely to experience
political turmoil or rapid changes in market or economic conditions than more
developed countries. In addition, the financial stability of issuers (including
governments) in emerging market countries may be more precarious than in other
countries.

o Management Risk:  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.

o Merger Arbitrage Risk:  Investments in companies that are expected to be, or
already are, the subject of a publicly announced transaction carry the risk that
the proposed or expected transaction may not be completed or may be completed on
less favorable terms than originally expected, which may lower performance.

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 of the Fund's Prospectus.

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 the contractual fee
waiver). Although your actual costs may be higher or lower, based on these
assumptions your costs would be:

Assuming Redemption at End of Period

Expense Example Touchstone Moderate Growth Allocation Fund (USD $)	Class A	Class C	Class Y	Institutional
Expense Example, with Redemption, 1 Year	703	311	110	110
Expense Example, with Redemption, 3 Years	1,060	736	603	7,352

Touchstone Moderate Growth Allocation Fund Class C	211	736	1,325	2,923

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 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 portfolio turnover rate of the Fund was
77.44% of the average value of its portfolio.

The Fund's Principal Investment Strategies

The Fund is a "fund-of-funds," which seeks to achieve its investment goal by
primarily investing in a diversified portfolio of affiliated underlying equity
and fixed-income funds (although a portion of its assets may be invested in
cash, cash equivalents, or in money market funds). These affiliated underlying
funds, in turn, invest in a variety of U.S. and foreign equity and fixed-income
securities.

The following table details, under normal circumstances, how the Fund expects to
allocate its assets among equity and fixed-income funds.

Equity Fund Allocation   Fixed-Income Fund Allocation
        70-90%                      10-30%

The Fund's sub-advisor, Ibbotson Associates, Inc. ("Ibbotson"), seeks to develop
an optimal model allocation among underlying funds using an analysis that looks
at forecasted returns, standard deviations in historical returns, and the
correlation of the performance of different market sectors.  The Fund may invest
0-45% of its assets in any individual underlying fund.

Ibbotson and the Fund's investment advisor agree from time to time upon the universe
of underlying funds that Ibbotson may consider when making allocation decisions.
Ibbotson's analysis in selecting and weighting the underlying funds from that
universe includes historical returns-based style analysis, holdings-based style
analysis, manager interviews, relative and absolute performance, including
correlations with other underlying funds as well as corresponding benchmarks,
and historical volatility (the variability of returns from one period to the next).
When considering equity funds, Ibbotson focuses on the underlying funds' foreign
and domestic exposure, market capitalization ranges, use of derivative strategies,
and investment style (growth vs. value). When considering fixed-income funds,
Ibbotson's primary focus is the overall level of risk in the type of fixed income
securities in which the underlying funds invest and on maximizing current income
and long-term capital growth.

Ibbotson, subject to approval by the Fund's investment advisor, may change the
Fund's target allocation to each asset class, the underlying funds in each asset
class (including adding or deleting underlying funds), or target allocations to
each underlying fund without prior approval from or notice to shareholders.

Decisions to sell shares of the underlying funds are made to adjust an underlying
fund's target allocation based on Ibbotson's view of the Fund's characteristics
and other allocation criteria, for cash flow resulting from redemptions, or as a
result of periodic rebalancing of the Fund's holdings. For information on the
underlying funds, please see the section entitled "Additional Information Regarding
the Underlying Funds" under "Investment Strategies and Risks" in the Fund's Prospectus.

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.

Risks of Fund of Funds Structure: The value of an investment in the Fund is
based on the performance of the underlying funds in which it invests and the
allocation of its assets among those funds. The underlying funds may change
their investment goals, policies or practices and there can be no assurance that
the underlying funds will achieve their respective investment goals. Because the
Fund invests in mutual funds, it bears a proportionate share of the expenses
charged by the underlying funds in which it invests. The principal risks of an
investment in the Fund include the principal risks of investing in the
underlying funds.

The Fund is exposed to the risks of the underlying funds in which it invests in
direct proportion to the amount of assets the Fund allocates to each underlying
fund. To the extent that the Fund invests more of its assets in one underlying
fund than another, the Fund will have greater exposure to the risks of that
underlying fund. One underlying fund may buy the same security that another
underlying fund is selling. You would indirectly bear the costs of both trades.
In addition, you may receive taxable gains from portfolio transactions by the
underlying funds, as well as taxable gains from the Fund's transactions in
shares of the underlying funds. The Fund's ability to achieve its investment
goal depends upon Ibbotson's skill in selecting the best mix of underlying
funds. There is the risk that Ibbotson's evaluations and assumptions regarding
the underlying funds may be incorrect in view of actual market conditions.

The underlying funds are expected to be subject to the following principal
risks.

o Underlying Equity Fund Risks: These underlying funds are subject to the risk
that stock prices will fall (or rise with respect to short positions) over short
or extended periods of time.  Individual companies may report poor results or
be negatively affected by industry and/or economic trends and developments.
Conversely, the risk of price increases with respect to securities sold short
will also cause a decline in the value of the underlying fund's shares. The
prices of securities issued by these companies may decline in response to such
developments, which could result in a decline in the value of the underlying
fund's shares. The risks of investing in underlying equity funds include risks
specific to their investment strategies, such as investment style risk and
capitalization risk.

o Underlying Fixed Income Funds Risks: The prices of an underlying fund's
fixed income securities respond to economic developments, particularly interest
rate changes, as well as to perceptions about the creditworthiness of individual
issuers, including governments. Other principal risks include call risk and
high-yield debt ("junk bond") risk. Call risk refers to situations when an issuer
prepays (or "calls") a debt obligation prior to maturity and an underlying fund
holding that debt  must invest the resulting proceeds at lower interest rates.
High-yield debt risk refers to non-investment grade debt obligations ("junk bonds")
that carry a higher risk of default by the issuer, resulting in losses to the
underlying fund, and are generally considered speculative and less liquid than
investment-grade debt obligations.

o Derivatives Risk: Certain of the underlying funds may invest in derivatives,
such as futures, options or swap contracts, to pursue their investment goals.
The use of such derivatives may expose an underlying fund to additional risks
that it would not be subject to if it invested directly in the securities
underlying those derivatives, including the risk of counterparty default.
These additional risks could cause an underlying fund to experience losses
to which it would otherwise not be subject. An underlying fund may use
derivatives to gain exposure to (or hedge exposure against) a particular market,
currency or instrument, to adjust the underlying fund's duration or attempt to
manage interest rate risk, and for certain other purposes consistent with its
investment strategy.  An underlying fund may not fully benefit from or may
lose money on derivative investments.

o Foreign Securities Risk: Certain underlying funds may invest in foreign
securities, which pose risks in addition to those posed by domestic securities
because political and economic events unique in a country or region will affect
those markets and their issuers. These events will not necessarily affect the
U.S. economy or similar issuers located in the United States. In addition,
investments in foreign securities are generally denominated in foreign currency.
Foreign markets may be less liquid and more volatile than U.S. markets and offer
less protection to investors. Emerging markets may be more likely to experience
political turmoil or rapid changes in market or economic conditions than more
developed countries. In addition, the financial stability of issuers (including
governments) in emerging market countries may be more precarious than in other
countries.

o Management Risk: 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.

o Merger Arbitrage Risk: Investments in companies that are expected to be, or
already are, the subject of a publicly announced transaction carry the risk that
the proposed or expected transaction may not be completed or may be completed on
less favorable terms than originally expected, which may lower performance.

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 of the Fund's Prospectus.

Strategy [Heading]	rr_StrategyHeading	The Fund's Principal Investment Strategies
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund's sub-advisor, Analytic Investors, LLC ("Analytic"), seeks to achieve the Fund's investment goal by investing the Fund's assets in a combination of equity securities, high quality short-term debt securities and derivative instruments. Equity Strategy. The Fund normally invests at least 80% of its assets in equity securities. This is a non-fundamental investment policy that can be changed by the Fund upon 60 days' prior notice to shareholders.  The Fund invests primarily in long and short positions in U.S. large-cap stocks included in the Russell 1000® Index, although the Fund may invest in small- and mid-cap equity securities. The Fund buys securities "long" that Analytic believes will outperform and sells securities "short" that Analytic believes will underperform. The Fund intends to take long and short equity positions that may vary over time based on Analytic's assessment of market conditions and other factors. The Fund's long equity exposure is ordinarily expected to range from 80% to 130% and its short equity exposure from 0% to 70% of the Fund's net assets, excluding cash. The Fund may take short positions at the higher end of this range when it has reduced its written call options positions under the options strategy (as described below) and may during these periods hold a substantial portion of the Fund's total assets in high quality short-term debt securities, cash, or cash equivalents. Analytic selects common stocks and other equity securities for the Fund using a proprietary system that ranks securities according to a quantitative model.  The model attempts to determine a security's intrinsic value by evaluating variables such as relative valuation, price momentum, company fundamentals, liquidity and risk. Options Strategy. Analytic seeks to reduce the overall portfolio risk through the use of options. The Fund's options strategy primarily focuses on the use of writing (selling) call options on equity indexes or index exchange traded funds ("ETFs"). For these purposes, the Fund treats options on indexes and ETFs as being written on securities having an aggregate value equal to the face or notional amount of the index or ETF subject to the option. The Fund may sell call options on broad-based domestic equity indexes or ETFs, such as the S&P 100® Index, as well as on narrower market indexes or ETFs or on indexes or ETFs of companies in a particular industry or sector. The Fund may also sell call options on foreign indexes or ETFs. The Fund seeks to write options on broad and narrow-based indexes and ETFs that correlate with the price movements of the Fund's equity securities. The Fund may also buy index put options to help protect the Fund from market declines that may occur in the future as the value of index put options increases as the prices of the stocks constituting the index decrease. However, during periods of market appreciation, the value of the index put option decreases as these stocks increase in price.  The Fund may also write (sell) covered call options on individual equity securities. The Fund may also purchase put options on individual equity securities which it owns. Other Derivative Strategies. In addition to the options strategy, the Fund may use other derivatives for a variety of purposes, including: to hedge against market and other risks in the portfolio; manage cash flows; and maintain market exposure and adjust the characteristics of its investments to more closely approximate those of its benchmark, with reduced transaction costs. Analytic may also use futures contracts to seek to gain broad market exposure and/or to hedge against market and other risks in the Fund's portfolio.    The Fund may engage in frequent and active trading of securities as part of its principal investment strategy. Analytic generally considers selling a security when it reaches fair value estimate, when the company's fundamentals do not appear to justify the current price, when there has been or there is an expectation of an adverse change in the company's fundamentals, when the risks of the security unexpectedly rise, or when other investment opportunities appear more attractive.
Risk [Heading]	rr_RiskHeading	The Principal Risks
Risk Narrative [Text Block]	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. Covered Call Options Risk:  Investments in covered calls involve certain risks. These risks include: o Limited Gains. When the Fund writes a covered call option, the Fund makes an obligation to deliver a security it already owns at an agreed-upon strike price on or before a predetermined date in the future in return for a premium. By selling a covered call option, the Fund may forego the opportunity to benefit from an increase in the price of the underlying stock above the exercise price, but continues to bear the risk of a decline in the value of the underlying stock.  While the Fund receives a premium for writing the call option, the price the Fund realizes from the sale of stock upon exercise of the option could be substantially below its prevailing market price. o Lack of Liquidity for the Option. A liquid market may not exist for the option. If the Fund is not able to close out the options transaction, the Fund will not be able to sell the underlying security until the option expires or is exercised. o Lack of Liquidity for the Security.  The Fund's investment strategy may also result in a lack of liquidity of the purchase and sale of portfolio securities. Because the Fund will generally hold the stocks underlying the call option, the Fund may be less likely to sell the stocks in its portfolio to take advantage of new investment opportunities. Derivatives Risk: The Fund may invest in derivatives, such as futures and options contracts, options related to futures contracts or swap contracts, to pursue its investment goal. The use of such derivatives may expose the Fund to additional risks to which it would otherwise not be subject. The lack of a liquid secondary market for a particular derivative instrument may prevent the Fund from closing its derivative positions and could adversely impact its ability to achieve its goals and to realize profits or limit losses. Since transactions in derivatives may involve leverage, a relatively small price movement in a derivative may result in an immediate and substantial loss to the Fund. Equity Securities Risk: The Fund is subject to the risk that stock prices will fall (or rise with respect to short positions) over short or extended periods of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by these companies may decline in response to such developments, which could result in a decline in the value of the Fund's shares. Conversely, the risk of price increases with respect to securities sold short will also cause a decline in the value of the Fund's shares. Management Risk: 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. Large-Cap Risk: Large-cap risk is the risk that stocks of larger companies may underperform relative to those of small and mid-sized companies. Larger cap companies may be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes, and also may not be able to attain the high growth rate of successful smaller companies, especially during extended periods of economic expansion. Futures Contracts Risk: A futures contract provides for the future sale by one party and purchase by another party of a specified quantity of the security or other financial instrument at a specified price and time. A futures contract on an index is an agreement in which two parties agree to take or make delivery of an amount of cash equal to the difference between the value of the index at the close of the last trading day of the contract and the price at which the index contract was originally written. The risks associated with futures include: the potential inability to terminate or sell a position, the lack of a liquid secondary market for the Fund's position and the risk that the counterparty to the transaction will not meet its obligations. Foreign Securities Risk: Investing in foreign securities poses additional risks since political and economic events unique in a country or region will affect those markets and their issuers. These events will not necessarily affect the U.S. economy or similar issuers located in the United States. Foreign markets may be less liquid and more volatile than U.S. markets and offer less protection to investors. Index and ETF Call Options Risk: Writing index and ETF call options is intended to reduce the Fund's volatility and provide income, although it may also reduce the Fund's ability to profit from increases in the value of its equity portfolio. Portfolio Turnover Risk: The risk that high portfolio turnover is likely to lead to increased Fund expenses that may result in lower investment returns. High portfolio turnover is also likely to result in higher short-term capital gains taxable to shareholders. Short Sales Risk: When selling a security short, the Fund will sell a security it does not own at the then-current market price. The Fund borrows the security to deliver to the buyer and is obligated to buy the security at a later date so it can return the security to the lender. If a security sold short increases in price, the Fund may have to cover its short position at a higher price than the short sale price, resulting in a loss. To borrow the security, the Fund also may be required to pay a premium, which would increase the cost of the security sold short. The amount of any gain will be decreased, and the amount of any loss increased, by the amount of the premium, dividends, interest or expenses the Fund may be required to pay in connection with the short sale. In addition, a lender may request, or market conditions may dictate, that securities sold short be returned to the lender on short notice, and the Fund may have to buy the securities sold short at an unfavorable price. If this occurs, any anticipated gain to the Fund may be reduced or eliminated or the short sale may result in a loss. In addition, because the Fund's loss on a short sale arises from increases in the value of the security sold short, such loss is theoretically unlimited. By contrast, the Fund's loss on a long position arises from decreases in the value of the security and is limited by the fact that a security's value cannot drop below zero. Leverage Risk: By engaging in certain derivative strategies or investing the proceeds received from selling securities short, the Fund is employing leverage, which creates special risks. The use of leverage may increase the Fund's exposure to long or short equity positions and make any change in the Fund's net asset value greater than without the use of leverage. Leverage generally results in increased volatility of returns. 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 of the Fund's Prospectus.

[1] The Total Annual Fund Operating Expenses do not correlate to the ratio of expenses to average net assets that are included in the Fund's Annual Report dated July 31, 2012, which reflects the operating expenses of the Fund and does not include Acquired Fund Fees and Expenses.

[2] Touchstone Advisors 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 in order to limit annual fund operating expenses to 1.55%, 2.30%, 1.30% and 1.25%, for Class A shares, Class C shares, Class Y shares, and Institutional shares, respectively. This expense limitation will remain in effect until at least April 16, 2014, but can be terminated by a vote of the Board of Trustees of the Fund if they deem the termination to be beneficial to the Fund shareholders. Touchstone Advisors is entitled to recoup, subject to approval by the Board of Trustees of the Fund, such amounts reduced or reimbursed for a period of up to three (3) 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 "Contractual Fee Waiver Agreement" under the section entitled "The Funds' Management" in the Fund's Prospectus for more information.

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 the contractual fee
waiver). Although your actual costs may be higher or lower, based on these
assumptions your costs would be:

Assuming Redemption at End of Period

Expense Example, with Redemption, 5 Years	2,059	1,906	1,374	1,485
Expense Example, with Redemption, 10 Years	3,741	3,971	2,929	3,216

Assuming No Redemption

Expense Example, No Redemption (USD $)	Expense Example, No Redemption, 1 Year	Expense Example, No Redemption, 3 Years	Expense Example, No Redemption, 5 Years	Expense Example, No Redemption, 10 Years
Touchstone Dynamic Equity Fund Class C	359	1,115	1,906	3,971

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 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 portfolio turnover rate
of the Fund was 233.99% of the average value of its portfolio.

The Fund's Principal Investment Strategies

The Fund's sub-advisor, Analytic Investors, LLC ("Analytic"), seeks to achieve
the Fund's investment goal by investing the Fund's assets in a combination of
equity securities, high quality short-term debt securities and derivative
instruments.

Equity Strategy. The Fund normally invests at least 80% of its assets in equity
securities. This is a non-fundamental investment policy that can be changed by
the Fund upon 60 days' prior notice to shareholders.  The Fund invests primarily
in long and short positions in U.S. large-cap stocks included in the Russell
1000® Index, although the Fund may invest in small- and mid-cap equity securities.
The Fund buys securities "long" that Analytic believes will outperform and sells
securities "short" that Analytic believes will underperform. The Fund intends to
take long and short equity positions that may vary over time based on Analytic's
assessment of market conditions and other factors. The Fund's long equity exposure
is ordinarily expected to range from 80% to 130% and its short equity exposure
from 0% to 70% of the Fund's net assets, excluding cash. The Fund may take short
positions at the higher end of this range when it has reduced its written call
options positions under the options strategy (as described below) and may during
these periods hold a substantial portion of the Fund's total assets in high
quality short-term debt securities, cash, or cash equivalents.

Analytic selects common stocks and other equity securities for the Fund using a
proprietary system that ranks securities according to a quantitative model.  The
model attempts to determine a security's intrinsic value by evaluating variables
such as relative valuation, price momentum, company fundamentals, liquidity and
risk.

Options Strategy. Analytic seeks to reduce the overall portfolio risk through
the use of options. The Fund's options strategy primarily focuses on the use of
writing (selling) call options on equity indexes or index exchange traded funds
("ETFs"). For these purposes, the Fund treats options on indexes and ETFs as
being written on securities having an aggregate value equal to the face or
notional amount of the index or ETF subject to the option. The Fund may sell
call options on broad-based domestic equity indexes or ETFs, such as the S&P
100® Index, as well as on narrower market indexes or ETFs or on indexes or ETFs
of companies in a particular industry or sector. The Fund may also sell call
options on foreign indexes or ETFs. The Fund seeks to write options on broad
and narrow-based indexes and ETFs that correlate with the price movements of
the Fund's equity securities.

The Fund may also buy index put options to help protect the Fund from market
declines that may occur in the future as the value of index put options increases
as the prices of the stocks constituting the index decrease. However, during
periods of market appreciation, the value of the index put option decreases
as these stocks increase in price.  The Fund may also write (sell) covered
call options on individual equity securities. The Fund may also purchase put
options on individual equity securities which it owns.

Other Derivative Strategies. In addition to the options strategy, the Fund may
use other derivatives for a variety of purposes, including: to hedge against
market and other risks in the portfolio; manage cash flows; and maintain market
exposure and adjust the characteristics of its investments to more closely
approximate those of its benchmark, with reduced transaction costs. Analytic
may also use futures contracts to seek to gain broad market exposure and/or to
hedge against market and other risks in the Fund's portfolio.
  
The Fund may engage in frequent and active trading of securities as part of its
principal investment strategy. Analytic generally considers selling a security
when it reaches fair value estimate, when the company's fundamentals do not
appear to justify the current price, when there has been or there is an
expectation of an adverse change in the company's fundamentals, when the risks
of the security unexpectedly rise, or when other investment opportunities appear
more attractive.

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.

Covered Call Options Risk:  Investments in covered calls involve certain risks.
These risks include:

o Limited Gains. When the Fund writes a covered call option, the Fund makes
an obligation to deliver a security it already owns at an agreed-upon strike
price on or before a predetermined date in the future in return for a premium.
By selling a covered call option, the Fund may forego the opportunity to
benefit from an increase in the price of the underlying stock above the
exercise price, but continues to bear the risk of a decline in the value of the
underlying stock.  While the Fund receives a premium for writing the call
option, the price the Fund realizes from the sale of stock upon exercise of the
option could be substantially below its prevailing market price.

o Lack of Liquidity for the Option. A liquid market may not exist for the option.
If the Fund is not able to close out the options transaction, the Fund will not
be able to sell the underlying security until the option expires or is exercised.

o Lack of Liquidity for the Security.  The Fund's investment strategy may also
result in a lack of liquidity of the purchase and sale of portfolio securities.
Because the Fund will generally hold the stocks underlying the call option, the
Fund may be less likely to sell the stocks in its portfolio to take advantage
of new investment opportunities.

Derivatives Risk: The Fund may invest in derivatives, such as futures and
options contracts, options related to futures contracts or swap contracts, to
pursue its investment goal. The use of such derivatives may expose the Fund to
additional risks to which it would otherwise not be subject. The lack of a
liquid secondary market for a particular derivative instrument may prevent the
Fund from closing its derivative positions and could adversely impact its
ability to achieve its goals and to realize profits or limit losses. Since
transactions in derivatives may involve leverage, a relatively small price
movement in a derivative may result in an immediate and substantial loss to the
Fund.

Equity Securities Risk: The Fund is subject to the risk that stock prices will
fall (or rise with respect to short positions) over short or extended periods of
time. Individual companies may report poor results or be negatively affected by
industry and/or economic trends and developments. The prices of securities
issued by these companies may decline in response to such developments, which
could result in a decline in the value of the Fund's shares. Conversely, the
risk of price increases with respect to securities sold short will also cause a
decline in the value of the Fund's shares.

Management Risk: 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.

Large-Cap Risk: Large-cap risk is the risk that stocks of larger companies may
underperform relative to those of small and mid-sized companies. Larger cap
companies may be unable to respond quickly to new competitive challenges, such
as changes in technology and consumer tastes, and also may not be able to attain
the high growth rate of successful smaller companies, especially during extended
periods of economic expansion.

Futures Contracts Risk: A futures contract provides for the future sale by one
party and purchase by another party of a specified quantity of the security or
other financial instrument at a specified price and time. A futures contract on
an index is an agreement in which two parties agree to take or make delivery of
an amount of cash equal to the difference between the value of the index at the
close of the last trading day of the contract and the price at which the index
contract was originally written. The risks associated with futures include: the
potential inability to terminate or sell a position, the lack of a liquid
secondary market for the Fund's position and the risk that the counterparty to
the transaction will not meet its obligations.

Foreign Securities Risk: Investing in foreign securities poses additional risks
since political and economic events unique in a country or region will affect
those markets and their issuers. These events will not necessarily affect the
U.S. economy or similar issuers located in the United States. Foreign markets
may be less liquid and more volatile than U.S. markets and offer less protection
to investors.

Index and ETF Call Options Risk: Writing index and ETF call options is intended
to reduce the Fund's volatility and provide income, although it may also reduce
the Fund's ability to profit from increases in the value of its equity portfolio.

Portfolio Turnover Risk: The risk that high portfolio turnover is likely to
lead to increased Fund expenses that may result in lower investment returns.
High portfolio turnover is also likely to result in higher short-term capital
gains taxable to shareholders.

Short Sales Risk: When selling a security short, the Fund will sell a security
it does not own at the then-current market price. The Fund borrows the security
to deliver to the buyer and is obligated to buy the security at a later date so
it can return the security to the lender. If a security sold short increases in
price, the Fund may have to cover its short position at a higher price than the
short sale price, resulting in a loss. To borrow the security, the Fund also
may be required to pay a premium, which would increase the cost of the security
sold short. The amount of any gain will be decreased, and the amount of any
loss increased, by the amount of the premium, dividends, interest or expenses
the Fund may be required to pay in connection with the short sale. In addition,
a lender may request, or market conditions may dictate, that securities sold
short be returned to the lender on short notice, and the Fund may have to buy
the securities sold short at an unfavorable price. If this occurs, any
anticipated gain to the Fund may be reduced or eliminated or the short sale may
result in a loss. In addition, because the Fund's loss on a short sale arises
from increases in the value of the security sold short, such loss is
theoretically unlimited. By contrast, the Fund's loss on a long position arises
from decreases in the value of the security and is limited by the fact that a
security's value cannot drop below zero.

Leverage Risk: By engaging in certain derivative strategies or investing the
proceeds received from selling securities short, the Fund is employing leverage,
which creates special risks. The use of leverage may increase the Fund's
exposure to long or short equity positions and make any change in the Fund's net
asset value greater than without the use of leverage. Leverage generally
results in increased volatility of returns.

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 of the Fund's
Prospectus.

Touchstone Advisors is entitled to recoup, subject to approval by the Board of Trustees of the Fund, such amounts reduced or reimbursed for a period of up to three (3) 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.

Strategy [Heading]	rr_StrategyHeading	The Fund's Principal Investment Strategies
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	Under normal market conditions, the Fund invests primarily in equity securities of "emerging growth companies", as defined below.  Equity securities primarily includes common stocks. Although the Fund may invest in emerging growth companies of any size, the Fund emphasizes small- and mid-cap companies in its portfolio. For purposes of this Fund, small- and mid-cap companies include companies with market values generally within the range of market values of issuers included in the Russell 2500™ Growth Index. The index measures the performance of the small to mid-cap growth segment of the U.S. equity universe. It includes those Russell 2500 companies with higher price-to-book ratios and higher forecasted growth values. Copper Rock Capital Partners, LLC ("Copper Rock"), the Fund's sub-advisor, considers an "emerging growth company" to be a company that exhibits high quality, growth characteristics. Copper Rock employs a fundamental, bottom-up investment approach that focuses on identifying emerging companies that Copper Rock believes exhibit the potential for strong and sustainable revenue and earnings growth, strong financial and competitive positions, and are led by strong management teams. Copper Rock sells or reduces a position when the target price for a stock is attained, there is a change in the company's management team or business objectives, or when there is deterioration in a company's fundamentals. Copper Rock seeks to construct a portfolio that is diversified across sectors and industries. The Fund may engage in frequent and active trading of securities as part of its principal investment strategy.
Risk [Heading]	rr_RiskHeading	The Principal Risks
Risk Narrative [Text Block]	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. Equity Securities Risk: The Fund is subject to the risk that stock prices will fall over short or extended periods of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by these companies may decline in response to such developments, which could result in a decline in the value of the Fund's shares. Management Risk: 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. Mid-Cap Risk: The Fund is subject to the risk that medium-capitalization stocks may underperform other types of stocks or the equity markets as a whole. Stocks of mid-sized companies may be subject to more abrupt or erratic market movements than stocks of larger, more established companies. Mid-sized companies may have limited product lines or financial resources, and may be dependent upon a particular niche of the market. Small-Cap Risk: The Fund at times may be primarily invested in small-capitalization companies. The Fund is subject to the risk that small-capitalization stocks may underperform other types of stocks or the equity markets as a whole. Small-cap stock risk is the risk that stocks of smaller companies may be subject to more abrupt or erratic market movements than stocks of larger, more established companies. Small companies may have limited product lines or financial resources, or may be dependent upon a small or inexperienced management group. In addition, small-cap stocks typically are traded in lower volume, and their issuers typically are subject to greater degrees of changes in their earnings and prospects. Growth Investing Risk: Growth oriented funds may underperform when value investing is in favor and growth stocks may be more volatile than other stocks because they are more sensitive to investor perceptions of the issuing company's growth of earnings potential. Portfolio Turnover Risk: The risk that high portfolio turnover is likely to lead to increased Fund expenses that may result in lower investment returns. High portfolio turnover is also likely to result in higher short-term capital gains taxable to shareholders. 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 of the Fund's Prospectus.

[1] Class C shares commenced operations on April 16, 2012. Class C shares would have had substantially similar annual returns because the shares are invested in the same portfolio. Annual returns would differ only to the extent that the Classes have different expenses.

[2] The Total Annual Fund Operating Expenses do not correlate to the ratio of expenses to average net assets that are included in the Fund's Annual Report dated July 31, 2012, which reflects the operating expenses of the Fund and does not include Acquired Fund Fees and Expenses.

[3] Touchstone Advisors 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 in order to limit annual fund operating expenses to 1.39%, 2.14%, 1.14%, and 0.99%, for Class A shares, Class C shares, Class Y shares, and Institutional shares, respectively. This expense limitation will remain in effect until at least April 16, 2014, but can be terminated by a vote of the Board of Trustees of the Fund if they deem the termination to be beneficial to the Fund shareholders. Touchstone Advisors is entitled to recoup, subject to approval by the Board of Trustees of the Fund, such amounts reduced or reimbursed for a period of up to three (3) 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 "Contractual Fee Waiver Agreement" under the section entitled "The Funds' Management" in the Fund's Prospectus for more information.

[4] "Other Expenses" for Class C shares have been restated to reflect estimated amounts for the current fiscal year.

TOUCHSTONE INTERNATIONAL EQUITY FUND SUMMARY

The Fund's Investment Goal

The Fund seeks to provide investors with long-term capital appreciation.

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 for Class A
shares 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 56 and in
the section entitled "Choosing a Share Class" in the Fund's SAI on page 61.

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees Touchstone International Equity Fund (USD $)	Class A	Class C	Class Y	Institutional
Maximum Sales Charge (Load) Imposed on Purchases (as a percentage of offering price)	5.75%	none	none	none
Maximum Deferred Sales Charge (Load) (as a percentage of original purchase price or the amount redeemed, whichever is less)	none	1.00%	none	none
Wire Redemption Fee	15	15	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 International Equity Fund		Class A	Class C		Class Y	Institutional
Management Fees		0.90%	0.90%		0.90%	0.90%
Distribution and/or Service (12b-1) Fees		0.25%	1.00%		none	none
Other Expenses		7.60%	0.94%	[1]	5.08%	1.01%
Total Annual Fund Operating Expenses	[2]	8.75%	2.84%		5.98%	1.91%
Fee Waivers and/or Expense Reimbursement	[3]	(7.36%)	(0.70%)		(4.84%)	(0.92%)
Total Annual Fund Operating Expenses After Fee Waivers and/or Expense Reimbursement		1.39%	2.14%		1.14%	0.99%

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 the contractual
fee waiver). Although your actual costs may be higher or lower, based on these
assumptions your costs would be:

Assuming Redemption at End of Period

Expense Example Touchstone International Equity Fund (USD $)	Class A	Class C	Class Y	Institutional
Expense Example, with Redemption, 1 Year	708	317	116	101
Expense Example, with Redemption, 3 Years	1,905	764	1,016	443
Expense Example, with Redemption, 5 Years	3,512	1,390	2,264	881
Expense Example, with Redemption, 10 Years	7,032	3,077	5,278	2,100

Assuming No Redemption

Expense Example, No Redemption (USD $)	Expense Example, No Redemption, 1 Year	Expense Example, No Redemption, 3 Years	Expense Example, No Redemption, 5 Years	Expense Example, No Redemption, 10 Years
Touchstone International Equity Fund Class C	217	764	1,390	3,077

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 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 portfolio turnover rate
of the Fund was 54.85% of the average value of its portfolio.

The Fund's Principal Investment Strategies

The Fund normally invests at least 80% of its assets in equity of non-U.S.
issuers. This is a non-fundamental investment policy that can be changed by
the Fund upon 60 days' prior notice to shareholders.  The Fund primarily
invests its assets in common stock of issuers located in developed markets.
Generally, the Fund limits its investments in any country to 25% or less of
its total assets, except that the Fund may invest more than 25% of its assets
in issuers organized in Japan or the United Kingdom or in securities quoted
or denominated in the Japanese yen, the British pound, or the euro.

The Fund's sub-advisor, Acadian Asset Management LLC ("Acadian"), uses stock
factors in an effort to predict how well each security will perform relative
to its region/industry peer group and applies separate models to forecast peer
group returns. The two forecasts are then combined to determine a world-relative
return forecast for each stock in the allowable universe, and Acadian uses a
sophisticated portfolio optimization system to trade off the expected return
of the stocks with such considerations as the client's benchmark index, desired
level of risk, transaction cost estimates, available liquidity, and other
requirements. Acadian considers selling a security whose forecast has
deteriorated and may adjust its buy and sell decisions based on shifts in the
risk characteristics of a stock relative to other potential substitutes, the
overall portfolio and the benchmark.

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.

Equity Securities Risk: The Fund is subject to the risk that stock prices will
fall over short or extended periods of time. Individual companies may report
poor results or be negatively affected by industry and/or economic trends and
developments. The prices of securities issued by these companies may decline in
response to such developments, which could result in a decline in the value of
the Fund's shares.

Management Risk: 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.

Foreign Securities Risk: Investing in foreign securities poses additional risks
since political and economic events unique in a country or region will affect
those markets and their issuers. Because the Fund may invest a large portion of
its assets in securities of companies located in Japan and the United Kingdom,
the Fund's performance may be impacted by social, political, and economic
conditions within Japan and the United Kingdom. These events will not necessarily
affect the U.S. economy or similar issuers located in the United States. In
addition, investments in foreign securities are generally denominated in foreign
currency. As a result, changes in the value of those currencies compared to the
U.S. dollar may affect (positively or negatively) the value of the Fund's
investments. These currency movements may happen separately from, or in response
to, events that do not otherwise affect the value of the security in the issuer's
home country. There is a risk that foreign securities may not be subject to
accounting standards or governmental supervision comparable to U.S. companies and
that less public information about their operations may exist. There is risk
associated with the clearance and settlement procedures in non-U.S. markets,
which may be unable to keep pace with the volume of securities transactions and
may cause delays. Foreign markets may be less liquid and more volatile than U.S.
markets and offer less protection to investors. Over-the-counter securities may
also be less liquid than exchange-traded securities.

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 of the Fund's Prospectus.

The Fund's Performance

The bar chart and the performance table below illustrate the risks and volatility
of an investment in the Fund by showing changes in the Fund's performance from
calendar year to calendar year and by showing how the  Fund's average annual total
returns for 1 year, 5 years, and since inception compare with the MSCI EAFE Index.
The bar chart does not reflect any sales charges, which would reduce your return.

Touchstone Balanced Allocation Fund Class C	203	700	1,254	2,766

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 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 portfolio turnover rate
of the Fund was 75.77% of the average value of its portfolio.

The Fund's Principal Investment Strategies

The Fund is a "fund-of-funds," which seeks to achieve its investment goal by
primarily investing in a diversified portfolio of affiliated underlying equity
and fixed-income funds (although a portion of its assets may be invested in
cash, cash equivalents, or in money market funds). These affiliated underlying
funds, in turn, invest in a variety of U.S. and foreign equity and fixed-income
securities.

The following table details, under normal circumstances, how the Fund expects to
allocate its assets among equity and fixed-income funds.

Equity Fund Allocation   Fixed-Income Fund Allocation
        50-70%                      30-50%

The Fund's sub-advisor, Ibbotson Associates, Inc. ("Ibbotson"), seeks to develop
an optimal model allocation among underlying funds using an analysis that looks
at forecasted returns, standard deviations in historical returns, and the
correlation of the performance of different market sectors. The Fund may invest
0-45% of its assets in any individual underlying fund.

Ibbotson and the Fund's investment advisor agree from time to time upon the
universe of underlying funds that Ibbotson may consider when making allocation
decisions. Ibbotson's analysis in selecting and weighting the underlying funds
from that universe includes historical returns-based style analysis, holdings-based
style analysis, manager interviews, relative and absolute performance, including
correlations with other underlying funds as well as corresponding benchmarks, and
historical volatility (the variability of returns from one period to the next).
When considering equity funds, Ibbotson focuses on the underlying funds' foreign
and domestic exposure, market capitalization ranges, use of derivative strategies,
and investment style (growth vs. value). When considering fixed-income funds,
Ibbotson's primary focus is the overall level of risk in the type of fixed income
securities in which the underlying funds invest and on maximizing current income
and long-term capital growth.

Ibbotson, subject to approval by the Fund's investment advisor, may change the
Fund's target allocation to each asset class, the underlying funds in each asset
class (including adding or deleting underlying funds), or target allocations to
each underlying fund without prior approval from or notice to shareholders.

Decisions to sell shares of the underlying funds are made to adjust an underlying
fund's target allocation based on Ibbotson's view of the Fund's characteristics
and other allocation criteria, for cash flow resulting from redemptions, or as a
result of periodic rebalancing of the Fund's holdings. For information on the
underlying funds, please see the section entitled "Additional Information Regarding
the Underlying Funds" under "Investment Strategies and Risks" in the Fund's Prospectus.

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.

Risks of Fund of Funds Structure: The value of an investment in the Fund is
based on the performance of the underlying funds in which it invests and the
allocation of its assets among those funds. The underlying funds may change
their investment goals, policies or practices and there can be no assurance that
the underlying funds will achieve their respective investment goals. Because the
Fund invests in mutual funds, it bears a proportionate share of the expenses
charged by the underlying funds in which it invests. The principal risks of an
investment in the Fund include the principal risks of investing in the underlying
funds.

The Fund is exposed to the risks of the underlying funds in which it invests in
direct proportion to the amount of assets the Fund allocates to each underlying
fund. To the extent that the Fund invests more of its assets in one underlying
fund than another, the Fund will have greater exposure to the risks of that
underlying fund. One underlying fund may buy the same security that another
underlying fund is selling. You would indirectly bear the costs of both trades.
In addition, you may receive taxable gains from portfolio transactions by the
underlying funds, as well as taxable gains from the Fund's transactions in
shares of the underlying funds. The Fund's ability to achieve its investment
goal depends upon Ibbotson's skill in selecting the best mix of underlying
funds. There is the risk that Ibbotson's evaluations and assumptions regarding
the underlying funds may be incorrect in view of actual market conditions.

The underlying funds are expected to be subject to the following principal risks.

o Underlying Equity Fund Risks: These underlying funds are subject to the risk
that stock prices will fall (or rise with respect to short positions) over short
or extended periods of time. Individual companies may report poor results or be
negatively affected by industry and/or economic trends and developments.
Conversely, the risk of price increases with respect to securities sold short
will also cause a decline in the value of the underlying fund's shares. The
prices of securities issued by these companies may decline in response to such
developments, which could result in a decline in the value of the underlying
fund's shares. The risks of investing in underlying equity funds include risks
specific to their investment strategies, such as investment style risk and
capitalization risk.

o Underlying Fixed-Income Funds Risks: The prices of an underlying fund's fixed
income securities respond to economic developments, particularly interest rate
changes, as well as to perceptions about the creditworthiness of individual
issuers, including governments. Other principal risks include call risk and
high-yield debt ("junk bond") risk. Call risk refers to situations when an
issuer prepays (or "calls") a debt obligation prior to maturity and an
underlying fund holding that debt must invest the resulting proceeds at lower
interest rates. High-yield debt risk refers to non-investment grade debt
obligations ("junk bonds") that carry a higher risk of default by the issuer,
resulting in losses to the underlying fund, and are generally considered
speculative and less liquid than investment-grade debt obligations.

o Derivatives Risk: Certain of the underlying funds may invest in derivatives,
such as futures, options or swap contracts, to pursue their investment goals.
The use of such derivatives may expose an underlying fund to additional risks
that it would not be subject to if it invested directly in the securities
underlying those derivatives, including the risk of counterparty default.
These additional risks could cause an underlying fund to experience losses to
which it would otherwise not be subject. An underlying fund may use derivatives
to gain exposure to (or hedge exposure against) a particular market, currency
or instrument, to adjust the underlying fund's duration or attempt to manage
interest rate risk, and for certain other purposes consistent with its
investment strategy. An underlying fund may not fully benefit from or may lose
money on derivative investments.

o Foreign Securities Risk:  Certain underlying funds may invest in foreign
securities, which pose risks in addition to those posed by domestic securities
because political and economic events unique in a country or region will affect
those markets and their issuers. These events will not necessarily affect the
U.S. economy or similar issuers located in the United States. In addition,
investments in foreign securities are generally denominated in foreign currency.
Foreign markets may be less liquid and more volatile than U.S. markets and offer
less protection to investors. Emerging markets may be more likely to experience
political turmoil or rapid changes in market or economic conditions than more
developed countries. In addition, the financial stability of issuers (including
governments) in emerging market countries may be more precarious than in other
countries.

o Management Risk: 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.

o Merger Arbitrage Risk: Investments in companies that are expected to be, or
already are, the subject of a publicly announced transaction carry the risk that
the proposed or expected transaction may not be completed or may be completed on
less favorable terms than originally expected, which may lower performance.

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 of the Fund's Prospectus.

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 the contractual fee
waiver). Although your actual costs may be higher or lower, based on these
assumptions your costs would be:

Assuming Redemption at End of Period

Expense Example Touchstone Conservative Allocation Fund (USD $)	Class A	Class C	Class Y	Institutional
Expense Example, with Redemption, 1 Year	684	291	90	90
Expense Example, with Redemption, 3 Years	1,000	671	465	356

Touchstone Conservative Allocation Fund Class C	191	671	1,211	2,689

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 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 portfolio turnover rate
of the Fund was 88.66% of the average value of its portfolio.

The Fund's Principal Investment Strategies

The Fund is a "fund-of-funds," which seeks to achieve its investment goal by
primarily investing in a diversified portfolio of affiliated underlying equity
and fixed-income funds (although a portion of its assets may be invested in
cash, cash equivalents, or in money market funds). These affiliated underlying
funds, in turn, invest in a variety of U.S. and foreign equity and fixed-income
securities.

The following table details, under normal circumstances, how the Fund expects to
allocate its assets among equity and fixed-income funds.

Equity Fund Allocation   Fixed-Income Fund Allocation
        20-40%                      60-80%

The Fund's sub-advisor, Ibbotson Associates, Inc. ("Ibbotson"), seeks to develop
an optimal model allocation among underlying funds using an analysis that looks
at forecasted returns, standard deviations in historical returns, and the
correlation of the performance of different market sectors. The Fund may invest
0-45% of its assets in any individual underlying fund.

Ibbotson and the Fund's investment advisor agree from time to time upon the
universe of underlying funds that Ibbotson may consider when making allocation
decisions. Ibbotson's analysis in selecting and weighting the underlying funds
from that universe includes historical returns-based style analysis,
holdings-based style analysis, manager interviews, relative and absolute
performance, including correlations with other underlying funds as well as
corresponding benchmarks, and historical volatility (the variability of returns
from one period to the next). When considering equity funds, Ibbotson focuses
on the underlying funds' foreign and domestic exposure, market capitalization
ranges, use of derivative strategies, and investment style (growth vs. value).
When considering fixed-income funds, Ibbotson's primary focus is the overall
level of risk in the type of fixed-income securities in which the underlying
funds invest and on maximizing current income and long-term capital growth.

Ibbotson, subject to approval by the Fund's investment advisor, may change the
Fund's target allocation to each asset class, the underlying funds in each
asset class (including adding or deleting underlying funds), or target allocations
to each underlying fund without prior approval from or notice to shareholders.

Decisions to sell shares of the underlying funds are made to adjust an underlying
fund's target allocation based on Ibbotson's view of the Fund's characteristics
and other allocation criteria, for cash flow resulting from redemptions, or as a
result of periodic rebalancing of the Fund's holdings. For information on the
underlying funds, please see the section entitled "Additional Information
Regarding the Underlying Funds" under "Investment Strategies and Risks" in the
Fund's Prospectus.

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.

Risks of Fund of Funds Structure: The value of an investment in the Fund is
based on the performance of the underlying funds in which it invests and the
allocation of its assets among those funds. The underlying funds may change
their investment goals, policies or practices and there can be no assurance
that the underlying funds will achieve their respective investment goals.
Because the Fund invests in mutual funds, it bears a proportionate share of
the expenses charged by the underlying funds in which it invests. The
principal risks of an investment in the Fund include the principal risks of
investing in the underlying funds.

The Fund is exposed to the risks of the underlying funds in which it invests in
direct proportion to the amount of assets the Fund allocates to each underlying
fund. To the extent that the Fund invests more of its assets in one underlying
fund than another, the Fund will have greater exposure to the risks of that
underlying fund. One underlying fund may buy the same security that another
underlying fund is selling. You would indirectly bear the costs of both trades.
In addition, you may receive taxable gains from portfolio transactions by the
underlying funds, as well as taxable gains from the Fund's transactions in
shares of the underlying funds. The Fund's ability to achieve its investment
goal depends upon Ibbotson's skill in selecting the best mix of underlying
funds. There is the risk that Ibbotson's evaluations and assumptions regarding
the underlying funds may be incorrect in view of actual market conditions.

The underlying funds are expected to be subject to the following principal
risks.

o Underlying Equity Fund Risks: These underlying funds are subject to the risk
that stock prices will fall (or rise with respect to short positions) over
short or extended periods of time.  Individual companies may report poor results
or be negatively affected by industry and/or economic trends and developments.
Conversely, the risk of price increases with respect to securities sold short
will also cause a decline in the value of the underlying fund's shares. The
prices of securities issued by these companies may decline in response to such
developments, which could result in a decline in the value of the underlying
fund's shares. The risks of investing in underlying equity funds include risks
specific to their investment strategies, such as investment style risk and
capitalization risk..

o Underlying Fixed Income Funds Risks: The prices of an underlying fund's fixed
income securities respond to economic developments, particularly interest rate
changes, as well as to perceptions about the creditworthiness of individual
issuers, including governments. Other principal risks include call risk and
high-yield debt ("junk bond") risk. Call risk refers to situations when an
issuer prepays (or "calls") a debt obligation prior to maturity and an
underlying fund holding that debt must invest the resulting proceeds at
lower interest rates. High-yield debt risk refers to non-investment grade
debt obligations ("junk bonds") that carry a higher risk of default by the
issuer, and are generally considered speculative and less liquid than
investment-grade debt obligations.

o Derivatives Risk: Certain of the underlying funds may invest in derivatives,
such as futures, options or swap contracts, to pursue their investment goals.
The use of such derivatives may expose an underlying fund to additional risks
that it would not be subject to if it invested directly in the securities
underlying those derivatives, including the risk of counterparty default.
These additional risks could cause an underlying fund to experience losses
to which it would otherwise not be subject. An underlying fund may use
derivatives to gain exposure to (or hedge exposure against) a particular
market, currency or instrument, to adjust the underlying fund's duration or
attempt to manage interest rate risk, and for certain other purposes
consistent with its investment strategy. An underlying fund may not fully
benefit from or may lose money on derivative investments.

o Foreign Securities Risk: Certain underlying funds may invest in foreign
securities, which pose risks in addition to those posed by domestic securities
because political and economic events unique in a country or region will affect
those markets and their issuers. These events will not necessarily affect the
U.S. economy or similar issuers located in the United States. In addition,
investments in foreign securities are generally denominated in foreign currency.
Foreign markets may be less liquid and more volatile than U.S. markets and offer
less protection to investors. Emerging markets may be more likely to experience
political turmoil or rapid changes in market or economic conditions than more
developed countries. In addition, the financial stability of issuers (including
governments) in emerging market countries may be more precarious than in other
countries.

Management Risk: 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.

Merger Arbitrage Risk: Investments in companies that are expected to be, or
already are, the subject of a publicly announced transaction carry the risk that
the proposed or expected transaction may not be completed or may be completed on
less favorable terms than originally expected, which may lower performance.

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 of the Fund's
Prospectus.

Ibbotson, subject to approval by the Fund's investment advisor, may change the Fund's target allocation to each asset class, the underlying funds in each asset class (including adding or deleting underlying funds), or target allocations to each underlying fund without prior approval from or notice to shareholders. Decisions to sell shares of the underlying funds are made to adjust an underlying fund's target allocation based on Ibbotson's view of the Fund's characteristics and other allocation criteria, for cash flow resulting from redemptions, or as a result of periodic rebalancing of the Fund's holdings. For information on the underlying funds, please see the section entitled "Additional Information Regarding the Underlying Funds" under "Investment Strategies and Risks" in the Fund's Prospectus.
Risk [Heading]	rr_RiskHeading	The Principal Risks
Risk Narrative [Text Block]	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. Risks of Fund of Funds Structure: The value of an investment in the Fund is based on the performance of the underlying funds in which it invests and the allocation of its assets among those funds. The underlying funds may change their investment goals, policies or practices and there can be no assurance that the underlying funds will achieve their respective investment goals. Because the Fund invests in mutual funds, it bears a proportionate share of the expenses charged by the underlying funds in which it invests. The principal risks of an investment in the Fund include the principal risks of investing in the underlying funds. The Fund is exposed to the risks of the underlying funds in which it invests in direct proportion to the amount of assets the Fund allocates to each underlying fund. To the extent that the Fund invests more of its assets in one underlying fund than another, the Fund will have greater exposure to the risks of that underlying fund. One underlying fund may buy the same security that another underlying fund is selling. You would indirectly bear the costs of both trades. In addition, you may receive taxable gains from portfolio transactions by the underlying funds, as well as taxable gains from the Fund's transactions in shares of the underlying funds. The Fund's ability to achieve its investment goal depends upon Ibbotson's skill in selecting the best mix of underlying funds. There is the risk that Ibbotson's evaluations and assumptions regarding the underlying funds may be incorrect in view of actual market conditions. The underlying funds are expected to be subject to the following principal risks. o Underlying Equity Fund Risks: These underlying funds are subject to the risk that stock prices will fall (or rise with respect to short positions) over short or extended periods of time.  Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. Conversely, the risk of price increases with respect to securities sold short will also cause a decline in the value of the underlying fund's shares. The prices of securities issued by these companies may decline in response to such developments, which could result in a decline in the value of the underlying fund's shares. The risks of investing in underlying equity funds include risks specific to their investment strategies, such as investment style risk and capitalization risk. o Underlying Fixed Income Funds Risks: The prices of an underlying fund's fixed income securities respond to economic developments, particularly interest rate changes, as well as to perceptions about the creditworthiness of individual issuers, including governments. Other principal risks include call risk and high-yield debt ("junk bond") risk. Call risk refers to situations when an issuer prepays (or "calls") a debt obligation prior to maturity and an underlying fund holding that debt  must invest the resulting proceeds at lower interest rates. High-yield debt risk refers to non-investment grade debt obligations ("junk bonds") that carry a higher risk of default by the issuer, resulting in losses to the underlying fund, and are generally considered speculative and less liquid than investment-grade debt obligations. o Derivatives Risk: Certain of the underlying funds may invest in derivatives, such as futures, options or swap contracts, to pursue their investment goals. The use of such derivatives may expose an underlying fund to additional risks that it would not be subject to if it invested directly in the securities underlying those derivatives, including the risk of counterparty default. These additional risks could cause an underlying fund to experience losses to which it would otherwise not be subject. An underlying fund may use derivatives to gain exposure to (or hedge exposure against) a particular market, currency or instrument, to adjust the underlying fund's duration or attempt to manage interest rate risk, and for certain other purposes consistent with its investment strategy.  An underlying fund may not fully benefit from or may lose money on derivative investments. o Foreign Securities Risk: Certain underlying funds may invest in foreign securities, which pose risks in addition to those posed by domestic securities because political and economic events unique in a country or region will affect those markets and their issuers. These events will not necessarily affect the U.S. economy or similar issuers located in the United States. In addition, investments in foreign securities are generally denominated in foreign currency. Foreign markets may be less liquid and more volatile than U.S. markets and offer less protection to investors. Emerging markets may be more likely to experience political turmoil or rapid changes in market or economic conditions than more developed countries. In addition, the financial stability of issuers (including governments) in emerging market countries may be more precarious than in other countries. o Management Risk: 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. o Merger Arbitrage Risk: Investments in companies that are expected to be, or already are, the subject of a publicly announced transaction carry the risk that the proposed or expected transaction may not be completed or may be completed on less favorable terms than originally expected, which may lower performance. 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 of the Fund's Prospectus.

[1] The Total Annual Fund Operating Expenses do not correlate to the ratio of expenses to average net assets that are included in the Fund's Annual Report dated July 31, 2012, which reflects the operating expenses of the Fund and does not include Acquired Fund Fees and Expenses.

[2] Expenses shown above have been restated to reflect a change in the Fund's contractual fee waiver, and will differ from the expenses shown in the Fund's Annual Report.

[3] Effective September 10, 2012, Touchstone Advisors 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 in order to limit annual fund operating expenses to 0.33%, 1.08%, 0.08%, and 0.08% for Class A shares, Class C shares, Class Y shares, and Institutional shares, respectively. This expense limitation will remain in effect until September 10, 2013, but can be terminated by a vote of the Board of Trustees of the Fund if they deem the termination to be beneficial to the Fund shareholders. Following the expiration of the contractual fee waiver above, Touchstone Advisors has contractually agreed to waive a portion of its fees and/or reimburse certain Fund expenses in order to limit annual fund operating expenses to 0.41%, 1.16%, 0.16%, and 0.16% for Class A shares, Class C shares, Class Y shares, and Institutional shares, respectively. This expense limitation will remain in effect until at least April 16, 2014 but can be terminated by a vote of the Board of Trustees of the Fund if they deem the termination to be beneficial to the Fund shareholders. Touchstone Advisors is entitled to recoup, subject to approval by the Board of Trustees of the Fund, such amounts reduced or reimbursed for a period of up to three (3) 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 "Contractual Fee Waiver Agreement" under the section entitled "The Funds' Management" in the Fund's Prospectus for more information. The fee table reflects only expense limitations in effect until April 16, 2014.

Strategy [Heading]	rr_StrategyHeading	The Fund's Principal Investment Strategies
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund is a "fund-of-funds," which seeks to achieve its investment goal by primarily investing in a diversified portfolio of affiliated underlying equity and fixed-income funds (although a portion of its assets may be invested in cash, cash equivalents, or in money market funds). These affiliated underlying funds, in turn, invest in a variety of U.S. and foreign equity and fixed-income securities. The following table details, under normal circumstances, how the Fund expects to allocate its assets among equity and fixed-income funds. Equity Fund Allocation   Fixed-Income Fund Allocation         50-70%                      30-50% The Fund's sub-advisor, Ibbotson Associates, Inc. ("Ibbotson"), seeks to develop an optimal model allocation among underlying funds using an analysis that looks at forecasted returns, standard deviations in historical returns, and the correlation of the performance of different market sectors. The Fund may invest 0-45% of its assets in any individual underlying fund. Ibbotson and the Fund's investment advisor agree from time to time upon the universe of underlying funds that Ibbotson may consider when making allocation decisions. Ibbotson's analysis in selecting and weighting the underlying funds from that universe includes historical returns-based style analysis, holdings-based style analysis, manager interviews, relative and absolute performance, including correlations with other underlying funds as well as corresponding benchmarks, and historical volatility (the variability of returns from one period to the next). When considering equity funds, Ibbotson focuses on the underlying funds' foreign and domestic exposure, market capitalization ranges, use of derivative strategies, and investment style (growth vs. value). When considering fixed-income funds, Ibbotson's primary focus is the overall level of risk in the type of fixed income securities in which the underlying funds invest and on maximizing current income and long-term capital growth. Ibbotson, subject to approval by the Fund's investment advisor, may change the Fund's target allocation to each asset class, the underlying funds in each asset class (including adding or deleting underlying funds), or target allocations to each underlying fund without prior approval from or notice to shareholders. Decisions to sell shares of the underlying funds are made to adjust an underlying fund's target allocation based on Ibbotson's view of the Fund's characteristics and other allocation criteria, for cash flow resulting from redemptions, or as a result of periodic rebalancing of the Fund's holdings. For information on the underlying funds, please see the section entitled "Additional Information Regarding the Underlying Funds" under "Investment Strategies and Risks" in the Fund's Prospectus.
Risk [Heading]	rr_RiskHeading	The Principal Risks
Risk Narrative [Text Block]	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. Risks of Fund of Funds Structure: The value of an investment in the Fund is based on the performance of the underlying funds in which it invests and the allocation of its assets among those funds. The underlying funds may change their investment goals, policies or practices and there can be no assurance that the underlying funds will achieve their respective investment goals. Because the Fund invests in mutual funds, it bears a proportionate share of the expenses charged by the underlying funds in which it invests. The principal risks of an investment in the Fund include the principal risks of investing in the underlying funds. The Fund is exposed to the risks of the underlying funds in which it invests in direct proportion to the amount of assets the Fund allocates to each underlying fund. To the extent that the Fund invests more of its assets in one underlying fund than another, the Fund will have greater exposure to the risks of that underlying fund. One underlying fund may buy the same security that another underlying fund is selling. You would indirectly bear the costs of both trades. In addition, you may receive taxable gains from portfolio transactions by the underlying funds, as well as taxable gains from the Fund's transactions in shares of the underlying funds. The Fund's ability to achieve its investment goal depends upon Ibbotson's skill in selecting the best mix of underlying funds. There is the risk that Ibbotson's evaluations and assumptions regarding the underlying funds may be incorrect in view of actual market conditions. The underlying funds are expected to be subject to the following principal risks. o Underlying Equity Fund Risks: These underlying funds are subject to the risk that stock prices will fall (or rise with respect to short positions) over short or extended periods of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. Conversely, the risk of price increases with respect to securities sold short will also cause a decline in the value of the underlying fund's shares. The prices of securities issued by these companies may decline in response to such developments, which could result in a decline in the value of the underlying fund's shares. The risks of investing in underlying equity funds include risks specific to their investment strategies, such as investment style risk and capitalization risk. o Underlying Fixed-Income Funds Risks: The prices of an underlying fund's fixed income securities respond to economic developments, particularly interest rate changes, as well as to perceptions about the creditworthiness of individual issuers, including governments. Other principal risks include call risk and high-yield debt ("junk bond") risk. Call risk refers to situations when an issuer prepays (or "calls") a debt obligation prior to maturity and an underlying fund holding that debt must invest the resulting proceeds at lower interest rates. High-yield debt risk refers to non-investment grade debt obligations ("junk bonds") that carry a higher risk of default by the issuer, resulting in losses to the underlying fund, and are generally considered speculative and less liquid than investment-grade debt obligations. o Derivatives Risk: Certain of the underlying funds may invest in derivatives, such as futures, options or swap contracts, to pursue their investment goals. The use of such derivatives may expose an underlying fund to additional risks that it would not be subject to if it invested directly in the securities underlying those derivatives, including the risk of counterparty default. These additional risks could cause an underlying fund to experience losses to which it would otherwise not be subject. An underlying fund may use derivatives to gain exposure to (or hedge exposure against) a particular market, currency or instrument, to adjust the underlying fund's duration or attempt to manage interest rate risk, and for certain other purposes consistent with its investment strategy. An underlying fund may not fully benefit from or may lose money on derivative investments. o Foreign Securities Risk:  Certain underlying funds may invest in foreign securities, which pose risks in addition to those posed by domestic securities because political and economic events unique in a country or region will affect those markets and their issuers. These events will not necessarily affect the U.S. economy or similar issuers located in the United States. In addition, investments in foreign securities are generally denominated in foreign currency. Foreign markets may be less liquid and more volatile than U.S. markets and offer less protection to investors. Emerging markets may be more likely to experience political turmoil or rapid changes in market or economic conditions than more developed countries. In addition, the financial stability of issuers (including governments) in emerging market countries may be more precarious than in other countries. o Management Risk: 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. o Merger Arbitrage Risk: Investments in companies that are expected to be, or already are, the subject of a publicly announced transaction carry the risk that the proposed or expected transaction may not be completed or may be completed on less favorable terms than originally expected, which may lower performance. 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 of the Fund's Prospectus.

[1] The Total Annual Fund Operating Expenses do not correlate to the ratio of expenses to average net assets that are included in the Fund's Annual Report dated July 31, 2012, which reflects the operating expenses of the Fund and does not include Acquired Fund Fees and Expenses.

[2] Expenses shown above have been restated to reflect a change in the Fund's contractual fee waiver, and will differ from the expenses shown in the Fund's Annual Report.

[3] Effective September 10, 2012, Touchstone Advisors 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 in order to limit annual fund operating expenses to 0.33%, 1.08%, 0.08%, and 0.08% for Class A shares, Class C shares, Class Y shares, and Institutional shares, respectively. This expense limitation will remain in effect until September 10, 2013, but can be terminated by a vote of the Board of Trustees of the Fund if they deem the termination to be beneficial to the Fund shareholders. Following the expiration of the contractual fee waiver above, Touchstone Advisors has contractually agreed to waive a portion of its fees and/or reimburse certain Fund expenses in order to limit annual fund operating expenses to 0.41%, 1.16%, 0.16%, and 0.16% for Class A shares, Class C shares, Class Y shares, and Institutional shares, respectively. This expense limitation will remain in effect until at least April 16, 2014 but can be terminated by a vote of the Board of Trustees of the Fund if they deem the termination to be beneficial to the Fund shareholders. Touchstone Advisors is entitled to recoup, subject to approval by the Board of Trustees of the Fund, such amounts reduced or reimbursed for a period of up to three (3) 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 "Contractual Fee Waiver Agreement" under the section entitled "The Funds' Management" in the Fund's Prospectus for more information. The fee table reflects only expense limitations in effect until April 16, 2014.

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 the contractual fee waiver).
Although your actual costs may be higher or lower, based on these assumptions
your costs would be:

Assuming Redemption at End of Period

Expense Example Touchstone Emerging Growth Fund (USD $)	Class A	Class C	Class Y	Institutional
Expense Example, with Redemption, 1 Year	709	318	117	102
Expense Example, with Redemption, 3 Years	1,160	768	438	359
Expense Example, with Redemption, 5 Years	1,730	1,398	822	659
Expense Example, with Redemption, 10 Years	3,273	3,095	1,900	1,512

Assuming No Redemption

Expense Example, No Redemption (USD $)	Expense Example, No Redemption, 1 Year	Expense Example, No Redemption, 3 Years	Expense Example, No Redemption, 5 Years	Expense Example, No Redemption, 10 Years
Touchstone Emerging Growth Fund Class C	218	768	1,398	3,095

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 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 portfolio turnover rate
of the Fund was 172.76% of the average value of its portfolio.

The Fund's Principal Investment Strategies

Under normal market conditions, the Fund invests primarily in equity securities
of "emerging growth companies", as defined below.  Equity securities primarily
includes common stocks. Although the Fund may invest in emerging growth
companies of any size, the Fund emphasizes small- and mid-cap companies in its
portfolio. For purposes of this Fund, small- and mid-cap companies include
companies with market values generally within the range of market values of
issuers included in the Russell 2500™ Growth Index. The index measures the
performance of the small to mid-cap growth segment of the U.S. equity universe.
It includes those Russell 2500 companies with higher price-to-book ratios and
higher forecasted growth values.

Copper Rock Capital Partners, LLC ("Copper Rock"), the Fund's sub-advisor,
considers an "emerging growth company" to be a company that exhibits high
quality, growth characteristics. Copper Rock employs a fundamental, bottom-up
investment approach that focuses on identifying emerging companies that Copper
Rock believes exhibit the potential for strong and sustainable revenue and
earnings growth, strong financial and competitive positions, and are led by
strong management teams. Copper Rock sells or reduces a position when the
target price for a stock is attained, there is a change in the company's
management team or business objectives, or when there is deterioration in a
company's fundamentals. Copper Rock seeks to construct a portfolio that is
diversified across sectors and industries.

The Fund may engage in frequent and active trading of securities as part of its
principal investment strategy.

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.

Equity Securities Risk: The Fund is subject to the risk that stock prices will
fall over short or extended periods of time. Individual companies may report
poor results or be negatively affected by industry and/or economic trends and
developments. The prices of securities issued by these companies may decline in
response to such developments, which could result in a decline in the value of
the Fund's shares.

Management Risk: 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.

Mid-Cap Risk: The Fund is subject to the risk that medium-capitalization stocks
may underperform other types of stocks or the equity markets as a whole. Stocks
of mid-sized companies may be subject to more abrupt or erratic market movements
than stocks of larger, more established companies. Mid-sized companies may have
limited product lines or financial resources, and may be dependent upon a
particular niche of the market.

Small-Cap Risk: The Fund at times may be primarily invested in small-capitalization
companies. The Fund is subject to the risk that small-capitalization stocks may
underperform other types of stocks or the equity markets as a whole. Small-cap
stock risk is the risk that stocks of smaller companies may be subject to more
abrupt or erratic market movements than stocks of larger, more established
companies. Small companies may have limited product lines or financial resources,
or may be dependent upon a small or inexperienced management group. In addition,
small-cap stocks typically are traded in lower volume, and their issuers typically
are subject to greater degrees of changes in their earnings and prospects.

Growth Investing Risk: Growth oriented funds may underperform when value investing
is in favor and growth stocks may be more volatile than other stocks because they
are more sensitive to investor perceptions of the issuing company's growth of
earnings potential.

Portfolio Turnover Risk: The risk that high portfolio turnover is likely to
lead to increased Fund expenses that may result in lower investment returns.
High portfolio turnover is also likely to result in higher short-term capital
gains taxable to shareholders.

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 of the Fund's Prospectus.

or other tax-deferred account. After-tax returns are only shown for Institutional
shares and after-tax returns for other Classes will vary.

Institutional shares and Class A shares began operations on July 29, 2005, and
Class Y shares began operations on December 9, 2005. Class Y shares performance
was calculated using the historical performance of Class A shares for the periods
prior to December 9, 2005. The Class Y shares performance for this period has
been restated to exclude the maximum applicable sales charge for Class A shares.

[1] "Other Expenses" for Class C shares have been restated to reflect estimated amounts for the current fiscal year.

[2] The Total Annual Fund Operating Expenses do not correlate to the ratio of expenses to average net assets that are included in the Fund's Annual Report dated July 31, 2012, which reflects the operating expenses of the Fund and does not include Acquired Fund Fees and Expenses.

[3] Touchstone Advisors 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 in order to limit annual fund operating expenses to 1.39%, 2.14%, 1.14%, and 0.99%, for Class A shares, Class C shares, Class Y shares, and Institutional shares, respectively. This expense limitation will remain in effect until at least April 16, 2014, but can be terminated by a vote of the Board of Trustees of the Fund if they deem the termination to be beneficial to the Fund shareholders. Touchstone Advisors is entitled to recoup, subject to approval by the Board of Trustees of the Fund, such amounts reduced or reimbursed for a period of up to three (3) 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 "Contractual Fee Waiver Agreement" under the section entitled "The Funds' Management" in the Fund's Prospectus for more information.

[1] Class C shares commenced operations on April 16, 2012. Class C shares would have had substantially similar annual returns because the shares are invested in the same portfolio. Annual returns would differ only to the extent that the Classes have different expenses.
