Investment Objective, Heading	rr_ObjectiveHeading	Investment Objective
investment Objective, Primary	rr_ObjectivePrimaryTextBlock	The investment objective of The Teberg Fund (the "Fund") is to seek to maximize total return (capital appreciation plus income).
Expense, Heading	rr_ExpenseHeading	Fees and Expenses of the Fund
Expense, Narrative	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	rr_ShareholderFeesCaption	SHAREHOLDER FEES (fees paid directly from your investment)
Operating Expenses, Caption	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	rr_PortfolioTurnoverTextBlock	The Fund pays transaction costs 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 the most recent fiscal year, the Fund's portfolio turnover rate was 86.88% of the average value of its portfolio.

Expenses, Not Correlated to Ratio Due to Acquired Fund Fees	rr_ExpensesNotCorrelatedToRatioDueToAcquiredFundFees	The Total Annual Fund Operating Expenses for the Fund do not correlate to the Ratio of Expenses to Average Net Assets Before Expense Waiver provided in the Financial Highlights section of the statutory prospectus, which reflects the operating expenses of the Fund and does not include Acquired Fund Fees and Expenses ("AFFE").
Expense Example, Heading	rr_ExpenseExampleHeading	Example.
Expense Example, Narrative	rr_ExpenseExampleNarrativeTextBlock	This Example is intended to help you compare the cost of investing in 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.

Investment Strategy, Heading	rr_StrategyHeading	Principal Investment Strategies
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	To achieve the Fund's investment objective, the Advisor invests the Fund's assets primarily in shares of any number of other no-load and load-waived mutual funds, sometimes referred to in this Prospectus as "Underlying Funds." The Underlying Funds pursue their own investment objectives by investing in particular types of securities (e.g., equity or debt), emphasizing a particular investment style (e.g., value or growth), or emphasizing certain industries or sectors. Some of the Underlying Funds invest in the stocks of small, medium and large capitalization domestic or international companies while others invest in fixed-income securities of varying maturities (e.g., short-term, intermediate or long-term) and credit qualities (e.g., investment grade or lower than investment grade), including government and corporate bonds, as well as high-yield securities or "junk bonds." Over time, the Fund's asset mix is likely to consist of a combination of equity, fixed-income, or money market funds; however, the Fund reserves the right to invest all of its assets in any one of these asset classes depending upon market conditions and to actively trade in Underlying Funds. Additionally, the Fund may commit up to 80% of its net assets at any given time to Underlying Funds that invest in high-yield or "junk bond" securities. The Advisor is responsible for constructing and maintaining the allocation of the Fund's assets in a timely combination of Underlying Funds that maximizes the Fund's total return. The Advisor uses a "top down" approach to actively selecting Underlying Funds that begins with an analysis of the general economic outlook. The next step is to analyze historical market patterns with the goal of determining which categories and sectors are likely to perform well in certain economic conditions. Next, the Advisor analyzes the historical returns of a broad universe of mutual funds and selects those that exhibit the potential for superior growth based on factors including, but not limited to, their exposure to risk, historical performance, downside records, and competitive position. To determine when to sell Underlying Funds, the Advisor analyzes how the general economic outlook could impact certain categories and sectors based on historical market patterns. The Advisor continuously monitors the pricing of each Underlying Fund to identify if it is performing as anticipated with the goal of selling an Underlying Fund when it appears to have reached its expected growth potential. The Advisor may sell an Underlying Fund prior to reaching this growth level if the economic outlook changes or it appears that the Underlying Fund is not reacting to current conditions as it has to similar periods in the past. Because the Fund is a "fund of funds," you will indirectly bear your proportionate share of any fees and expenses charged by the Underlying Funds in which the Fund invests in addition to the expenses of the Fund. Actual Underlying Fund expenses are expected to vary with changes in the allocation of the Fund's assets among various Underlying Funds.
Risk, Heading	rr_RiskHeading	Principal Investment Risks
Risk, Narrative	rr_RiskNarrativeTextBlock	Losing all or a portion of your investment is a risk of investing in the Fund. The following additional risks could affect the value of your investment: · Management Risk. The risk that investment strategies employed by the Advisor in selecting the Underlying Funds and those used by the Underlying Funds in selecting investments may not result in an increase in the value of your investment equal to other investments or may cause your investment to lose value. · Stock Market Risk. The value of the Fund's shares will fluctuate based on the performance of the Underlying Funds of which the Fund owns shares and other factors affecting the securities markets generally. · Bond Market Risk. These risks apply to the extent the Underlying Funds hold fixed-income securities. Interest rate risk is the risk that interest rates may go up resulting in a decrease in the value of the securities held by the Underlying Funds. Credit risk is the risk that an issuer will not make timely payments of principal and interest. · High-Yield Securities Risk. The fixed-income securities held by Underlying Funds that are rated below investment grade (i.e., "junk bonds") are subject to additional risk factors such as increased possibility of default, illiquidity of the security, and changes in value based on public perception of the issuer. · Small and Medium Capitalization Companies Risk. Securities of smaller companies in which the Underlying Funds may invest involve greater risk than securities of larger companies because they can be subject to more abrupt or erratic share price changes than securities of larger, more established companies. · Non-Diversification Risk. The Fund is non-diversified, which means that compared with diversified funds, the Fund may invest a greater percentage of its assets in a particular Underlying Fund. The Fund's shares may be more susceptible to adverse changes in the value of a particular Underlying Fund than the shares of a diversified mutual fund. · Industry or Sector Emphasis Risk. To the extent that an Underlying Fund invests a substantial portion of its portfolio in a particular industry or sector, such Underlying Fund's shares may be more volatile and fluctuate more than shares of an Underlying Fund investing in a broader range of securities. · Underlying Funds Expense Risk. The Underlying Funds, which may include exchange-traded funds ("ETFs"), are either open-end or closed-end investment companies. ETFs are investment companies that are bought and sold on a national securities exchange. All Underlying Funds have management fees that are part of their costs. To the extent that the Fund invests in Underlying Funds, there will be some duplication of expenses because the Fund would bear its pro rata portion of such funds' management fees and operational expenses. · Portfolio Turnover Risk. A high portfolio turnover rate (100% or more) has the potential to result in the realization by the Fund and distribution to shareholders of a greater amount of capital gains than if the Fund had a low portfolio turnover rate. This may mean that you would be likely to have a higher tax liability. Distributions to shareholders of short-term capital gains are taxed as ordinary income under federal tax laws. When purchasing Fund securities through a broker, high portfolio turnover generally involves correspondingly greater brokerage commission expenses, which must be borne directly by the Fund. This Fund may be appropriate for investors who are: · seeking capital appreciation and income consistent with the assumption of an average level of market risk; · willing to leave their money invested in the Fund for at least five years; · able to tolerate a risk that they may experience share price fluctuations or lose money on their investment; or · able to tolerate the risks associated with investments in high-yield securities.
