Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	The Intermediate 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 Intermediate Fund's performance.

The Example assumes that you invest $10,000 in the Intermediate 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 Intermediate Fund's operating expenses remain the same (taking into account the Expense Caps only in the first year).

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies of the Intermediate Fund
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Intermediate Fund normally invests at least 80% of its net assets (plus any borrowings for investment purposes) in fixed income securities. The fixed income securities in which the Fund will generally invest include those of governments, agencies, inflation-protected securities, asset-backed securities, municipal bonds and companies across a wide range of industries and market capitalizations and are generally rated within the BBB-category or better by Standard & Poor's Rating Group ("Standard & Poor's") or the Baa3 category or better by Moody's Investors Services ("Moody's"). The Fund normally invests within the intermediate term structure of the yield curve and will seek to achieve its investment objective through duration tilts, sector allocations, credit exposures, and security selection. The maturities of the securities in which the Fund expects to invest will generally range from 1 to 10 years. The average-dollar weighted maturity of the securities in which the Fund expects to invest will generally range from 3 to 10 years. Duration tilts may be interpreted as differences in the duration of the Fund relative to duration of the benchmark. Duration is a measure of the sensitivity of the Fund's NAV to interest rate movements. For fixed-coupon bonds, duration can be intuitively defined as the average maturity of all bond payments, where each payment is weighted by its value. Duration tilts will be limited from 75% to 125% of the Barclays Capital Intermediate Government/Credit Index. The Advisor determines that a particular security should be purchased by evaluating macroeconomic factors including interest rate trends, monetary policy, inflation outlook, treasury supply and demand, interest rate volatility, the strategy duration target, and yield curve position. The Intermediate Fund may seek to enhance returns through the use of other investment strategies such as the use of options (for hedging purposes), investment in foreign securities, and in 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 emerging markets. Through its investment in foreign securities, the Fund may invest up to 20% of its net assets in American Depositary Receipts ("ADRs"). The Fund also may invest up to 20% of its net assets in other investment companies and may invest in the securities of small and medium-sized 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 Intermediate 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 Intermediate Fund
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	Losing all or a portion of your investment is a risk of investing in the Fund. The following principal risks could affect the value of your investment: ·  Asset-Backed Securities Risk. Asset-backed securities may decline in value        when defaults on the underlying assets occur and may exhibit additional           volatility in periods of changing interest rates. When interest rates decline,    the prepayment of assets underlying such securities may require the               Intermediate Fund to reinvest that money at lower prevailing interest rates,      resulting in reduced returns. ·  Credit Risk. The risk that the Intermediate Fund could lose money if the          issuer or guarantor of a fixed income security, or the counterparty to a          derivative contract, is unable or unwilling to meet its financial obligations. ·  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 Intermediate Fund will indirectly bear its proportionate share    of these costs. ·  Foreign and Emerging Market Securities Risk. The Intermediate 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 Intermediate Fund's investments. The risks are enhanced    in emerging markets. ·  Foreign Governments Investment Risk. The issuer of the foreign debt or the        governmental authorities that control the repayment of such debt may be unable    or unwilling to repay principal or interest when due, and the Intermediate        Fund may have limited recourse in the event of a default. The market prices of    debt obligations of foreign governments and their agencies, and the               Intermediate Fund's net asset value ("NAV"), may be more volatile than prices    of U.S. debt obligations. ·  Government-Sponsored Entities Risk. Securities issued by government-sponsored    entities may not be backed by the full faith and credit of the United States. ·  Inflation Protected Securities Risk. Inflation protected securities include       the risk that the rate of inflation will be lower than expected or that the       relevant index intended to measure the rate of inflation will not accurately      measure the rate of inflation and the securities will not work as intended. ·  Interest Rate Risk. The risk that fixed income securities will decline in         value because of an increase in interest rates; a fund with a longer average      portfolio duration will be more sensitive to changes in interest rates than a    fund with a shorter average portfolio duration. ·  Issuer Risk. The value of securities held by the Intermediate Fund may            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. ·  Management Risk. Management risk means that your investment in the                Intermediate Fund varies with the success and failure of the Advisor's            investment strategies and the Advisor's research, analysis and determination      of portfolio securities. ·  New Fund Risk. The Intermediate 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 Intermediate Fund may be appropriate for investors who: ·  Have a long-term investment horizon; and ·  Want to add an investment with potential for income and to diversify their        investment portfolio.

[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 Intermediate Fund to ensure that Net Annual Fund Operating Expenses (excluding acquired fund fees and expenses ("AFFE"), interest, taxes and extraordinary expenses) do not exceed 0.94% of average daily net assets of the Intermediate Fund's Class A shares and 0.69% of average daily net assets of the Intermediate Fund's Class I shares (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 Intermediate Fund for three years from the date they were waived or paid, subject to the Expense Caps.
