| Performance Narrative [Text Block] | The bar chart below shows how the Fund’s investment results have varied from year-to-year as represented by the performance of the Retail Class shares. The table below shows how the Fund’s average annual returns for 1, 5, and 10 years compare with those of a value-style securities market index and the returns of a broad-based market index and a secondary index which is more representative of the Fund’s Strategy. This information provides some indication of the risks of investing in the Fund. Past performance (before and after taxes) information is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available on the Fund’s website at www.beckercap.com/mutual-fund.

| Performance Table Not Relevant to Tax Deferred | After-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts (“IRAs”). |

| Performance Table Closing [Text Block] | After-tax returns are calculated using the historical highest individual federal marginal income tax rates in effect and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts (“IRAs”). The index returns presented above assume reinvestment of all distributions and exclude the effect of taxes and fees (if expenses and taxes were deducted, the actual returns of the Index would be lower). The “Return After Taxes on Distributions” shows the effect of taxable distributions (dividends and capital gains distributions), but assumes that you still hold Fund shares at the end of the period.
