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 SAM Global Equity Fund (the "Fund") is long-term growth of capital.
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 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 52% of the average value of its portfolio.
Portfolio Turnover, Rate	rr_PortfolioTurnoverRate	52.00%
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 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 a diversified portfolio of equity and equity-related securities issued by U.S. and non-U.S. companies that combine their market and financial strategy with a high level of environmental awareness and a clearly defined social policy ("Sustainable Leaders"). For purposes of the 80% policy, net assets include any borrowings for investment purposes. As part of its principal investment strategy, the Fund may invest in securities of foreign companies, including emerging markets companies, and companies with medium and small market capitalizations, including micro-cap stocks.
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. The Fund's foreign investments involve additional risks, including less liquidity, currency-rate fluctuations, political and economic instability and differences in financial reporting standards and securities market regulation. Emerging Markets Risks. The risks of foreign investments typically are greater in emerging markets due to factors such as smaller securities markets and lower trading volumes, less developed legal and accounting structures, substantial influence by an emerging market country's government over the private sector and potential high levels of inflation, deflation or currency devaluations. Sustainability Investment Criteria Risks. The Fund's sustainability investment criteria may limit the number of investment opportunities available to the Fund. The Fund's returns may be less than those funds that are not subject to such investment considerations. Companies that promote sustainability goals may not perform as well as companies that do not pursue such goals. Currency Risks. The value of the Fund's foreign holdings as measured in U.S. dollars may be affected unfavorably by changes in foreign currency exchange rates. The Fund may also incur costs in connection with conversions between various currencies. Small- and Medium-Capitalization Company Risks. Small-capitalization and medium-capitalization companies are often more volatile and less liquid than larger companies. Securities of these companies may be subject to greater and more abrupt price fluctuations and may be more susceptible to market pressures and business failures. Micro-Capitalization Company Risks. Micro-capitalization companies are generally even more volatile and less liquid relative to small-capitalization, medium-capitalization and large capitalization securities. 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.
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.
