Risk Return [Abstract]	rr_RiskReturnAbstract
Risk/Return [Heading]	rr_RiskReturnHeading	SUMMARY SECTION
Objective [Heading]	rr_ObjectiveHeading	Investment Objective.
Objective, Primary [Text Block]	rr_ObjectivePrimaryTextBlock	The investment objective of the Frontegra Phocas Small Cap Value Fund (the "Fund") is long-term total investment return through capital appreciation. This investment objective is fundamental and may not be changed without shareholder approval.
Expense [Heading]	rr_ExpenseHeading	Fees and Expenses of the Fund.
Expense Narrative [Text Block]	rr_ExpenseNarrativeTextBlock	This table describes the fees and expenses that you may pay if you buy and hold Institutional Class shares of the Fund.
Shareholder Fees Caption [Text]	rr_ShareholderFeesCaption	Shareholder Fees (fees paid directly from your investment)
Operating Expenses Caption [Text]	rr_OperatingExpensesCaption	Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)
Portfolio Turnover [Heading]	rr_PortfolioTurnoverHeading	Portfolio Turnover.
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 rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During its most recent fiscal year, the Fund had a portfolio turnover rate of 50% of the average value of its portfolio.
Portfolio Turnover, Rate	rr_PortfolioTurnoverRate	50.00%
Expenses Not Correlated to Ratio Due to Acquired Fund Fees [Text]	rr_ExpensesNotCorrelatedToRatioDueToAcquiredFundFees	Acquired Fund Fees and Expenses ("AFFE") are fees and expenses incurred by the Fund in connection with its investments in other investment companies. Total Annual Fund Operating Expenses shown will not correlate to the Fund's ratio of expenses to average net assets appearing in the Financial Highlights table, which does not include AFFE.
Expense Example [Heading]	rr_ExpenseExampleHeading	Example.
Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	The following example is intended to help you compare the cost of investing in the Institutional Class shares of the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same.
Expense Example by, Year, Caption [Text]	rr_ExpenseExampleByYearCaption	Although your actual costs may be higher or lower, based on these assumptions your costs would be:
Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategy.
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	Under normal market conditions, the Fund invests at least 80% of its net assets in domestic common stocks and other equity securities (including convertible preferred stocks and warrants) of small-capitalization companies, consistent with companies within the Russell 2000® Value Index. As of September 30, 2012, the largest market capitalization of a company in the Russell 2000® Value Index was $3.8 billion and the weighted average market capitalization was $1.1 billion. For purposes of the 80% policy, net assets include any borrowings for investment purposes. The Fund will pursue its investment objective by investing in a diversified portfolio of small-capitalization securities selling at discounts to their fair value as assessed by the investment and research team of Phocas Financial Corporation ("Phocas"), the Fund's subadviser. Phocas will typically invest in 80 to 120 companies with initial weightings between 0.50% to 1.50% of total Fund value in order to have broad industry representation and reduce individual security risk within the Fund.
Risk [Heading]	rr_RiskHeading	Principal Investment Risks.
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	Market Risks. The Fund's investments are subject to market risk, which may cause the value of the Fund's investments to decline. If the value of the Fund's investments goes down, the share price of the Fund will go down, and you may lose money. U.S. and international markets have experienced extreme volatility, reduced liquidity, credit downgrades, increased likelihood of default and valuation difficulties in recent years. Equity Securities Risks. Common stocks and other equity securities held by the Fund will fluctuate in value based on the earnings of the company and on general industry and market conditions, leading to fluctuations in the Fund's share price. Stock Selection Risks. The stocks selected for the Fund may decline in value or not increase in value when the stock market in general is rising. Foreign Securities Risks. Investments in securities of foreign companies involve additional risks, including less liquidity, currency-rate fluctuations, political and economic instability and differences in financial reporting standards and securities market regulation. Management Risks. The Fund is subject to management risk as an actively-managed investment portfolio and depends on the decisions of the portfolio managers to produce the desired results. Small Capitalization Company Risks. Securities of companies with small market capitalizations are often more volatile, less liquid and more susceptible to market pressures than larger companies. Value Investing Risks. The Fund invests primarily in value-style stocks, stocks whose prices Phocas believes are undervalued in relation to fundamental measures. Value stocks may never increase in price or pay dividends as anticipated by Phocas, or may decline even further if the market fails to recognize the company's value, if the factors that Phocas believes will increase the price do not occur or if a stock judged to be undervalued is actually appropriately priced. Sector Risks. Although Phocas selects stocks based on their individual merits, some economic sectors will represent a larger portion of the Fund's overall investment portfolio than other sectors. Potential negative market or economic developments affecting one of the larger sectors could have a greater impact on the Fund than on a fund with fewer holdings in that sector.
Risk Lose Money [Text]	rr_RiskLoseMoney	If the value of the Fund's investments goes down, the share price of the Fund will go down, and you may lose money.
Bar Chart and Performance Table [Heading]	rr_BarChartAndPerformanceTableHeading	Performance.
Performance Narrative [Text Block]	rr_PerformanceNarrativeTextBlock	The Fund is the successor to the Phocas Small Cap Value Fund (the "Predecessor Fund") pursuant to a reorganization that was completed on October 8, 2010. Prior to this date, the Fund had no investment operations. Accordingly, the performance and financial information for periods prior to October 8, 2010 is historical information for the Predecessor Fund. The Fund has investment objectives, strategies and policies substantially similar to the Predecessor Fund, which was advised by Phocas, the current subadviser to the Fund. The Predecessor Fund was subject to different expenses than the Institutional Class shares offered by this prospectus. Accordingly, the performance for the Predecessor Fund may differ from that of the Fund.    The return information provided in the following bar chart and table illustrates how the performance of the Fund can vary, which is one indication of the risks of investing in the Fund. The bar chart shows the changes in the Fund's performance from year to year. The table shows how the Fund's average annual returns compare with a broad measure of market performance. Please keep in mind that the Fund's past performance (before and after taxes) does not necessarily represent how it will perform in the future. Updated performance data is available on the Company's website at www.frontegra.com or by calling toll-free to 1-888-825-2100.

[4] Acquired Fund Fees and Expenses ("AFFE") are fees and expenses incurred by the Fund in connection with its investments in other investment companies. Total Annual Fund Operating Expenses shown will not correlate to the Fund's ratio of expenses to average net assets appearing in the Financial Highlights table, which does not include AFFE.

[5] Pursuant to an expense cap agreement between Frontegra Asset Management, Inc. ("Frontegra"), the Fund's investment adviser, and the Fund, Frontegra has contractually agreed to waive its management fee and/or reimburse the Fund's operating expenses to the extent necessary to ensure that the Fund's total operating expenses (excluding taxes, interest, brokerage commissions, AFFE and extraordinary expenses) do not exceed 1.10% of the Fund's average daily net assets for the Institutional Class shares. Frontegra is entitled to recoup the fees waived and/or expenses reimbursed within a three-year period from the time the expenses were incurred to the extent of the expense limitation. The expense cap agreement will continue in effect until October 31, 2013 with successive renewal terms of one year unless terminated by Frontegra or the Company prior to any such renewal. "Other Expenses" are presented before any waivers or expense reimbursements and have been restated to reflect estimated current expenses due to a decrease in the Fund's assets since fiscal year end.
