| 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 25.60% of the average value of its portfolio. |

| Expense Example [Heading] | rr_ExpenseExampleHeading | Example— | ||||||
| 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 | The Fund invests in a group of low-quality, high-risk, high yield corporate debt obligations. Under normal circumstances, at least 80% of the Fund’s net assets (plus any borrowings made for investment purposes) will be invested in corporate bonds rated Baa by Moody’s Investors Service (“Moody’s”) or BBB by S&P Global Ratings (“S&P”) or lower. As a result, this includes high yield/lower-rated debt securities (also known as “junk” bonds) that are rated by an independent rating agency to be non-investment grade (e.g., BB or lower by S&P or Ba or lower by Moody’s). Because of their low credit quality, these securities typically pay higher interest rates to compensate investors for the substantial credit risk they assume. The Fund may also invest in corporate issues that have defaulted. In addition, the Fund may invest in Rule 144A securities, which are generally privately placed securities purchased by qualified institutional buyers. While there are no restrictions on maturity, the Fund’s portfolio generally has an average maturity of less than ten years. The Fund seeks capital appreciation from selling bonds above the purchase price.
To select the securities in which to invest, the Fund’s sub-adviser conducts fundamental credit research on each issuer. The Fund will buy securities that the sub-adviser believes are attractively priced relative to current and expected fundamentals. The Fund may consider selling a security if, among other considerations, the issuer’s business fundamentals have deteriorated. |
||||||
| Strategy Portfolio Concentration [Text] | rr_StrategyPortfolioConcentration | The Fund invests in a group of low-quality, high-risk, high yield corporate debt obligations. Under normal circumstances, at least 80% of the Fund’s net assets (plus any borrowings made for investment purposes) will be invested in corporate bonds rated Baa by Moody’s Investors Service (“Moody’s”) or BBB by S&P Global Ratings (“S&P”) or lower. As a result, this includes high yield/lower-rated debt securities (also known as “junk” bonds) that are rated by an independent rating agency to be non-investment grade (e.g., BB or lower by S&P or Ba or lower by Moody’s).

| Bar Chart and Performance Table [Heading] | rr_BarChartAndPerformanceTableHeading | Fund Performance | ||||||
| Performance Narrative [Text Block] | rr_PerformanceNarrativeTextBlock | The following bar chart and table provide some indication of the risks of investing in the Fund. The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available at www.integrityvikingfunds.com or by calling 800-276-1262.
Prior to August 1, 2009, the Fund was managed by Integrity Money Management, Inc. Since August 1, 2009, the Fund has been managed by Viking Fund Management, LLC. In addition, effective May 5, 2008, the Fund replaced its sub-adviser. Accordingly, the results prior to May 5, 2008 were achieved while the Fund was sub-advised by its previous sub-advisor, and its investment strategies and techniques differed from those of, and may have produced different investment results than those achieved by, J.P. Morgan Investment Management Inc., which became the Fund’s sub-adviser effective May 5, 2008.
The bar chart below shows the variability of the Fund’s performance for Class A shares. The bar chart and highest/lowest quarterly returns that follow do not reflect sales charges, and if these charges were reflected, the returns would be less than those shown. |

| Integrity High Income 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 High Income 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 High Income Fund | Lower-Quality Debt Risk [Member] | ||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||
| Risk [Text Block] | rr_RiskTextBlock | Lower-Quality Debt Risk: Lower-quality debt securities (also known as “junk bonds”) and certain types of other securities involve greater risk of default or price changes due to changes in the credit quality of the issuer. The value of lower-quality debt securities and certain types of other securities often fluctuates in response to company, political, or economic developments and can decline significantly over short periods of time or during periods of general or regional economic difficulty. Lower-quality debt securities can be thinly traded or have restrictions on resale, making them difficult to sell at an acceptable price. The default rate for lower-quality debt securities is likely to be higher during economic recessions or periods of high interest rates. | ||||||
| Integrity High Income Fund | Credit Risk [Member] | ||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||
| Risk [Text Block] | rr_RiskTextBlock | Credit Risk: Credit risk is the risk that the credit strength of an issuer will weaken and/or an issuer of a security will fail to pay principal and interest in a timely manner, reducing the Fund’s total return. The Fund may invest in securities that are not investment grade and are generally considered speculative because they present a greater risk of loss, including default, than higher quality debt securities. Credit risk may be substantial for the Fund. | ||||||
| Integrity High Income Fund | Interest Rate Risk [Member] | ||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||
| Risk [Text Block] | rr_RiskTextBlock | Interest Rate Risk: Interest rate risk is the risk that debt securities will decline in value because of changes in interest rates. As nominal interest rates rise, the value of certain debt securities held by the Fund is likely to decrease. Debt securities with longer maturities tend to be more sensitive to changes in interest rates, usually making them more volatile than securities with shorter maturities. | ||||||
| Integrity High Income Fund | Income Risk [Member] | ||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||
| Risk [Text Block] | rr_RiskTextBlock | Income Risk: Income risk is the risk that the income from the Fund’s portfolio will decline because of falling market interest rates. This can result when the Fund invests the proceeds from new share sales, or from matured or called bonds, at market interest rates that are below the portfolio’s current earnings rate. | ||||||
| Integrity High Income 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 High Income Fund | Liquidity Risk [Member] | ||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||
| Risk [Text Block] | rr_RiskTextBlock | Liquidity Risk: Certain securities in which the Fund invests may be less readily marketable and may be subject to greater fluctuation in price than other securities. These features may make it more difficult to sell or buy a security at a favorable price or time. | ||||||
| Integrity High Income Fund | Management Risk [Member] | ||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||
| Risk [Text Block] | rr_RiskTextBlock | Management Risk: The Fund’s overall success depends on the sub-adviser’s ability to choose productive securities for the Fund. If the sub-adviser is unable to successfully choose productive securities, the Fund may underperform other funds with similar investment objectives. | ||||||
| Integrity High Income Fund | Market Volatility Risk [Member] | ||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||
| Risk [Text Block] | rr_RiskTextBlock | Market Volatility Risk: Market volatility risk is the risk that the value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies and/or general economic conditions. Price changes may be temporary or may last for extended periods. Volatile financial markets may expose the Fund to greater market and liquidity risk. | ||||||
| Integrity High Income 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 High Income 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. | ||||||
