Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	The Equity Income Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in the Annual Fund Operating Expenses or in the Example, affect the Equity Income Fund's performance.
Expense Breakpoint Discounts [Text]	rr_ExpenseBreakpointDiscounts	You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $25,000 in the Equity Income Fund.

Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	This Example is intended to help you compare the cost of investing in the Equity Income Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Equity Income Fund for the time periods indicated and then either redeem or do not 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 Equity Income Fund's operating expenses remain the same (taking into account the Expense Caps only in the first year). Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies of the Equity Income Fund
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Equity Income Fund normally invests at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities (including convertibles, preferred stocks, partnerships and limited partnerships). The Fund invests across a wide range of market capitalizations, while the overall portfolio maintains a large capitalization emphasis. The equity securities in which the Fund will generally invest include those which the Advisor believes have attractive fundamental characteristics, including stable or improving returns on equity, a solid balance sheet, and ample cash flow. The Fund seeks to achieve its investment objective through investment in strategically advantaged companies that generate free cash flow that can be used to reinvest in the company, pay down debt or distribute to shareholders in the form of dividends and/or share repurchases. The Equity Income Fund may seek to enhance returns through the use of other investment strategies such as the use of options (for hedging purposes), foreign securities, and other investment companies including exchange-traded funds ("ETFs"). The Fund may invest up to 20% of its net assets in put and call options. The Fund may invest up to 25% of its net assets in foreign securities, including in American Depositary Receipts ("ADRs") and emerging markets. The Fund may invest up to 20% of its net assets in other investment companies. The Advisor may sell a position if the fundamentals have deteriorated, a security becomes fully valued, or for purposes of portfolio construction and risk management. The Advisor may also sell a position if a better alternative becomes available. At the discretion of the Advisor, the Equity Income Fund may invest its assets in cash, cash equivalents, and high-quality, short-term debt securities and money market instruments for temporary defensive purposes in response to adverse market, economic or political conditions.
Risk [Heading]	rr_RiskHeading	Principal Risks of Investing in the Equity Income Fund
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	Losing all or a portion of your investment is a risk of investing in the Equity Income Fund. The following principal risks could affect the value of your investment: ·  Equity Risk. Stock prices may fluctuate widely over short or even extended        periods in response to company, market, or economic news. Stock markets also      tend to move in cycles, with periods of rising stock prices and periods of        falling stock prices. ·  ETF and Mutual Fund Risk. ETFs are typically open-end investment companies        that are bought and sold on a national securities exchange. Investment            companies (mutual funds) and ETFs have management fees that are part of their    costs, and the Equity Income Fund will indirectly bear its proportionate share    of these costs. ·  Foreign and Emerging Market Securities Risk. The Equity Income Fund may invest    in foreign securities which are subject to special risks. Foreign securities      can be more volatile than domestic (U.S.) securities. Securities markets of       other countries are generally smaller than U.S. securities markets. Many          foreign securities may be less liquid and more volatile than U.S. securities,    which could affect the Fund's investments. The risks are enhanced in emerging    markets. ·  Management Risk. Management risk means that your investment in the Equity         Income Fund varies with the success and failure of the Advisor's investment       strategies and the Advisor's research, analysis and determination of portfolio    securities. ·  Market and Issuer Risk. The risks that could affect the value of the Equity       Income Fund's shares and the total return on your investment include the          possibility that the securities held by the Fund will fluctuate as a result of    the movement of the overall stock market or of the value of the individual        securities held by the Fund. The value of securities held by the Fund may also    experience sudden, unpredictable drops in value or long periods of decline in    value due to reasons directly related to the issuer, including management         performance, financial leverage, and reduced demand for the issuer's goods and    services. ·  New Fund Risk. The Equity Income Fund is new with no operating history and        there can be no assurance that the Fund will grow to or maintain an               economically viable size. ·  Options Risk. Options on securities may be subject to greater fluctuations in    value than an investment in the underlying securities. Purchasing and writing    put and call options are highly specialized activities and entail greater than    ordinary investment risks. ·  Small and Medium Companies Risk. Investing in securities of small and medium      capitalization companies may involve greater volatility than investing in         larger and more established companies because small and medium capitalization    companies can be subject to more abrupt or erratic share price changes than       larger, more established companies.                                            The Equity Income Fund may be appropriate for investors who: ·  Have a long-term investment horizon; ·  Want to add an investment with potential for both income and capital              appreciation to diversify their investment portfolio;                          ·  Can accept the greater risks of investing in a portfolio with common stock        holdings; and                                                                  .  Are not primarily concerned with principal stability.

[2] Davidson Investment Advisors, Inc. (the "Advisor") has contractually agreed to waive all or a portion of its management fees and pay expenses of the Equity Income Fund to ensure that Net Annual Fund Operating Expenses (excluding acquired fund fees and expenses ("AFFE"), interest, taxes and extraordinary expenses) do not exceed 1.10% and 1.85% of average daily net assets of the Equity Income Fund's Class A and Class C shares, respectively (the "Expense Caps"). The Expense Caps will remain in effect through at least October 27, 2013, and may be terminated only by Advisors Series Trust's Board of Trustees (the "Board"). The Advisor may request recoupment of previously waived fees and paid expenses from the Equity Income Fund for three years from the date they were waived or paid, subject to the Expense Caps.
