| 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 the most recent fiscal period, the Fund’s portfolio turnover rate was 41.80% of the average value of its portfolio. |

| Expense Example Narrative [Text Block] | rr_ExpenseExampleNarrativeTextBlock | This Example is intended to help you compare the cost of investing in the Fund with the costs of investing in other mutual funds. The Example assumes you invest $10,000 in the Fund for the time periods indicated and then either redeem or do not redeem your shares at those periods. The Example also assumes that your investment has a 5% return each year, that the Fund’s operating expenses remain the same, and that the contractual expense limitation agreement remains in place for the first year. Although your actual costs may be higher or lower, based on these assumptions your costs would be: |

| Strategy [Heading] | rr_StrategyHeading | Principal Investment Strategies | |||||||||||||||||||||||||||||||||||||
| Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | To pursue its objective, the Fund normally invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in dividend-paying equity securities, including common stock and preferred stock, of companies. In addition, under normal market conditions, the Fund invests at least 65% of its net assets in equity securities that have consistently increased dividends for a period of at least 10 years. In determining whether a company has increased its dividend for a period of at least 10 years, the Fund’s Portfolio Management Team (“Team”) will account for the effect of any stock splits or spin-offs and exclude special dividends.
Although the investment process results in the Fund holding primarily large-cap companies, the Fund may invest in companies of any size. In selecting securities, the Team considers a combination of factors, including, but not limited to, dividend yield, dividend growth rate, earnings growth, price-to-earnings (P/E) multiples, valuation, credit rating, balance sheet strength, and volatility. The Team emphasizes dividend yield in selecting stocks for the Fund because the Team believes that, over time, dividend income can contribute significantly to total return and is a more consistent source of investment return than capital appreciation.
While the Fund does not concentrate in any one industry, from time to time, based on economic conditions, it may make significant investments in certain sectors.
The Fund may invest up to 30% of its net assets in foreign equity securities, including common stock and preferred stock.
The Team may consider selling a security if, among other considerations, the issuer’s business fundamentals have deteriorated or the issuer fails to raise its dividend. |

| Integrity Dividend Harvest Fund | Risk Lose Money [Member] | |||||||||||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | ||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | As with all mutual funds, there is the risk that you could lose money through your investment in the Fund. | |||||||||||||||||||||||||||||||||||||
| Integrity Dividend Harvest Fund | Risk Not Insured Depository Institution [Member] | |||||||||||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | ||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. | |||||||||||||||||||||||||||||||||||||
| Integrity Dividend Harvest Fund | Dividend-Paying Stock Risk [Member] | |||||||||||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | ||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Dividend-Paying Stock Risk: Because the Fund can only distribute what it earns, the Fund’s distributions to shareholders could decline when dividend income from stocks in the Fund’s portfolio declines. The Fund’s emphasis on dividend-paying stocks involves the risk that such stocks may fall out of favor with investors and underperform the market. Also, a company may reduce or eliminate its dividend, which could affect the Fund’s ability to generate income. Key factors that might cause a company to reduce or eliminate its dividend include deteriorating fundamentals or changes in priority of the uses of capital, among other factors. | |||||||||||||||||||||||||||||||||||||
| Integrity Dividend Harvest Fund | General Market Risk [Member] | |||||||||||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | ||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | General Market Risk: There is no assurance that the Fund will meet its investment objective. The prices of the securities in which the Fund invests may fluctuate as a result of market factors such as interest rates, credit spreads, or commodity prices, and the Fund’s share price and the value of your investment may change. Since the value of the Fund’s shares can go up or down, it is possible to lose money by investing in the Fund. | |||||||||||||||||||||||||||||||||||||
| Integrity Dividend Harvest Fund | Preferred Stock Risk [Member] | |||||||||||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | ||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Preferred Stock Risk: Preferred stocks
are subject to the risks associated with other types of equity securities, such as potential volatility, as well as additional risks,
such as risks related to deferral and omission of distributions; credit and subordination risk; interest rate risk; call, reinvestment
and income risk; liquidity risk; risks related to limited voting rights; and risks related to special redemption rights.

|||||||||||||||||||||||||||||||||||||
| Integrity Dividend Harvest Fund | Sector Risk [Member] | |||||||||||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | ||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Sector Risk: To the extent that the Fund focuses on particular sectors from time to time, the Fund may be subject to greater risk of the adverse developments in such areas of focus than a fund that invests in a wider variety of sectors. | |||||||||||||||||||||||||||||||||||||
| Integrity Dividend Harvest Fund | Risks of Foreign Securities (including Depositary Receipts) [Member] | |||||||||||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | ||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Risks of Foreign Securities (including Depositary Receipts): The Fund may invest in securities of non-U.S. issuers which have special risks. These risks include international economic and political developments, foreign government actions including restrictions on payments to non-domestic persons such as the Fund, less regulation, less information, currency fluctuations, and interruptions in currency flow. The Fund’s investments in foreign securities are typically in the form of sponsored or unsponsored depositary receipts, such as American Depositary Receipts (“ADRs”), which are subject to risks similar to those associated with other foreign securities. In addition, ownership of unsponsored depositary receipts may not entitle the Fund to financial and other reports from the issuer of the underlying security and certain costs related to the receipts that would otherwise be borne by the issuer of a sponsored depositary receipt may be passed through, in whole or in part, to holders of unsponsored receipts. Moreover, investments in depositary receipts may be less liquid and more volatile than the underlying shares in their primary trading market. If a depositary receipt is denominated in a different currency than its underlying securities, the Fund will be subject to the currency risk of both the investment in the depositary receipt and the underlying security. Any distributions paid to the holders of depositary receipts are usually subject to a fee charged by the depositary. Holders of depositary receipts may have limited voting rights, and investment restrictions in certain countries may adversely impact the value of depositary receipts because such restrictions may limit the ability to convert the equity shares into depositary receipts and vice versa. Such restrictions may cause the equity shares of the underlying issuer to trade at a discount or premium to the market price of the depositary receipts. | |||||||||||||||||||||||||||||||||||||
| Integrity Dividend Harvest Fund | Risks of Investments in Smaller Companies [Member] | |||||||||||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | ||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Risks of Investments in Smaller Companies: The securities of mid-capitalization and small-capitalization companies involve greater risks than those associated with larger, more established companies and may be subject to more abrupt or erratic price movements. Securities of such issuers may lack sufficient market liquidity to enable the Fund to effect sales at an advantageous time or without a substantial drop in price. Both mid-capitalization and small-capitalization companies often have narrower markets and more limited managerial and financial resources than larger, more established companies. As a result, their performance can be more volatile and they face greater risk of business failure, which could increase the volatility of the Fund’s portfolio. Generally, the smaller the company size, the greater these risks become. | |||||||||||||||||||||||||||||||||||||
| Integrity Dividend Harvest Fund | Valuation Risk [Member] | |||||||||||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | ||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Valuation Risk: The sales price the Fund could receive for any particular portfolio investment may differ from the Fund’s valuation of the investment, particularly for securities that trade in thin or volatile markets or that are valued using a fair value methodology. | |||||||||||||||||||||||||||||||||||||
| Integrity Dividend Harvest Fund | Cybersecurity Risk [Member] | |||||||||||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | ||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Cybersecurity Risk: Cybersecurity breaches may allow an unauthorized party to gain access to Fund assets, customer data, or proprietary information, or cause the Fund and/or its service providers to suffer data corruption or lose operational functionality. The Fund’s share price may decline as a result of unauthorized actions taken during a security breach or subsequent market activity in response to the security breach. | |||||||||||||||||||||||||||||||||||||
