The Mid Cap 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 year ended October 31, 2023, the Fund’s portfolio turnover rate was 40% of the average value of its portfolio.

Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Mid Cap Fund seeks to achieve its investment objective by investing at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities of mid‑capitalization companies. The Fund invests primarily in publicly traded stocks of U.S. companies which Congress Asset Management Company, LLP (the “Advisor”) considers to have a mid‑size market capitalization. The Mid Cap Fund defines mid‑capitalization companies as those whose market capitalization, at the time of purchase, are consistent with the market capitalizations of companies in the Russell Midcap Growth® Index. As of the last reconstitution date, June 26, 2023, the market capitalization of companies in the Russell Midcap Growth® Index ranged from $504 million to $49.4 billion. The Fund may invest any portion of the remaining 20% of its net assets in equity securities of small‑capitalization and large‑capitalization companies. The Fund may invest up to 20% of its total assets in U.S. dollar-denominated foreign equity securities, including through American Depositary Receipts (“ADRs”) and Global Depositary Receipts (“GDRs”) issued by U.S. depository banks, which are traded on U.S. exchanges. The Fund invests in companies that the Advisor believes are experiencing or will experience earnings growth. The Advisor
employs a “bottom‑up” approach to research and stock selection, which means that the Advisor bases its investments on a company’s future prospects and not on any significant economic or market cycle. The Advisor also uses a growth‑style approach to selecting securities with a focus on high quality companies. The Advisor’s fundamental approach emphasizes earnings growth and free cash flow. The Advisor may sell a security for a number of reasons including, but not limited to, if a determination is made that the security no longer meets its investment criteria or if a new security is judged more attractive than a current holding. The Mid Cap Fund may, from time to time, have significant exposure to one or more sectors of the market. As of October 31, 2022, 31.2% of the Fund’s net assets were invested in securities within the information technology sector.

Congress Mid Cap Growth Fund | General Market Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock General Market Risk: Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes due to a number of factors, including: inflation (or expectations for inflation); interest rates; global demand for particular products or resources; natural disasters or events; pandemic diseases; terrorism; regulatory events; and government controls. U.S. and international markets have experienced significant periods of volatility in recent years and months due to a number of economic, political and global macro factors which has resulted in disruptions to business operations and supply chains, stress on the global health care system, growth concerns in the U.S. and overseas, staffing shortages and the inability to meet consumer demand, and widespread concern and uncertainty. Continuing uncertainties regarding interest rates, rising inflation, political events, rising government debt in the U.S., and trade tensions also contribute to market volatility. Conflict, loss of life and disaster connected to ongoing armed conflict between Ukraine and Russia in Europe and Israel and Hamas in the Middle East could have severe adverse effects on the region, including significant adverse affects on the regional or global economies and the markets for certain securities. The U.S. and the European Union imposed sanctions on certain Russian individuals and companies, including certain financial institutions, and have limited certain exports and imports to and from Russia. The war has contributed to market volatility and may continue to do so.
Congress Mid Cap Growth Fund | Foreign Investment Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Foreign Investment Risk: Foreign securities involve increased risks due to political, social and economic developments abroad, as well as due to differences between U.S. and foreign regulatory practices. When the Fund invests in ADRs as a substitute for an investment directly in the underlying foreign shares, the Fund is exposed to the risk that the ADRs may not provide a return that corresponds precisely with that of the underlying foreign shares. GDRs generally are subject to the same risks as the foreign securities that they evidence or into which they may be converted.

The Large Cap Fund may also invest up to 20% of its net assets from time to time in equity securities of small-capitalization and mid‑capitalization companies. Equity securities in which the Fund may invest include common stock and preferred stock. The Large Cap Fund may also invest up to 20% of its total assets in U.S. dollar-denominated foreign equity securities, including through American Depositary Receipts (“ADRs”) and Global Depositary Receipts (“GDRs”) issued by U.S. depository banks, which are traded on U.S. exchanges.

Performance Narrative [Text Block] rr_PerformanceNarrativeTextBlock
The following performance information provides some indication of the risks of investing in the Fund.
The performance information shown for periods before September 15, 2017, reflects the historical performance of the Century Shares Trust, a series of Century Capital Management Trust (the “Accounting Survivor”). Effective as of the close of business on September 15, 2017, the Accounting Survivor was reorganized into the Fund (the “Reorganization”). As part of the Reorganization, Institutional Class shares of the Accounting Survivor were exchanged for Institutional Class shares of the Fund. As of the date of the Reorganization, the Accounting Survivor did not have any Retail Class shares outstanding. Upon completion of the Reorganization, the Fund assumed the performance, financial and other historical information of the Accounting Survivor. The Accounting Survivor and the Fund have substantially similar investment objectives and strategies. Disclosure differences between the investment objectives and strategies for the Accounting Survivor and the Fund have not resulted, and are not expected to result, in substantial differences in the actual management of the Accounting Survivor and the Fund. One of the two portfolio managers of the Accounting Survivor is a member of the portfolio management team of the Fund. The Fund has lower expenses than the Accounting Survivor (including a lower management fee). The Accounting Survivor’s performance would have been higher than that shown had it operated with the Fund’s current expense levels.
The bar chart below only illustrates how Institutional Class shares of the Fund’s total returns have varied from one calendar year to another over the past 10 years. The returns for the Fund’s Retail Class shares, both before and after taxes, may be lower than the returns shown in the bar chart below for the Institutional Class shares of the Fund, depending on the fees and expenses of the Retail Class shares. As the Fund’s expense ratio was lower than that of the Accounting Survivor at the time of the Reorganization for the Institutional Class shares, the Fund’s returns would have been higher than those shown here. The table below illustrates how the Fund’s average annual total returns for the 1‑year, 5-year and 10-year periods compare with a domestic broad‑based market index and a secondary index provided to offer a broader market perspective. The Fund’s performance, before and after taxes, is not necessarily an indication of how the Fund will perform in the future. Updated performance is available on the Fund’s website at https://congress-mutual-funds.web.app.

U.S. and international markets have experienced significant periods of volatility in recent years and months due to a number of economic, political and global macro factors which has resulted in disruptions to business operations and supply chains, stress on the global health care system, growth concerns in the U.S. and overseas, staffing shortages and the inability to meet consumer demand, and widespread concern and uncertainty. Continuing uncertainties regarding interest rates, rising inflation, political events, rising government debt in the U.S., and trade tensions also contribute to market volatility. Conflict, loss of life and disaster connected to ongoing armed conflict between Ukraine and Russia in Europe and Israel and Hamas in the Middle East could have severe adverse effects on the region, including significant adverse affects on the regional or global economies and the markets for certain securities. The U.S. and the European Union imposed sanctions on certain Russian individuals and companies, including certain financial institutions, and have limited certain exports and imports to and from Russia. The war has contributed to market volatility and may continue to do so.

Risk [Text Block] rr_RiskTextBlock Foreign Investment Risk: Foreign securities involve increased risks due to political, social and economic developments abroad, as well as due to differences between U.S. and foreign regulatory practices. When the Fund invests in ADRs as a substitute for an investment directly in the underlying foreign shares, the Fund is exposed to the risk that the ADRs may not provide a return that corresponds precisely with that of the underlying foreign shares. GDRs generally are subject to the same risks as the foreign securities that they evidence or into which they may be converted.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Small Cap Fund seeks to achieve its investment objective by investing at least 80% of its net assets (plus any borrowings for investment purposes) in the common stocks of small‑capitalization companies. The Small Cap Fund defines small‑capitalization companies as those companies with market capitalizations not exceeding the highest market capitalization in the Russell 2000® Growth Index during the preceding 12 months. As of the last reconstitution date, June 26, 2023, the market capitalization of companies in the Russell 2000® Growth Index ranged from $17.8 million to $11.4 billion. The Fund may invest any portion of the remaining 20% of its net assets in the equity securities of companies with market capitalizations that may be higher or lower than the range of issuer market capitalizations represented in the Russell 2000® Growth Index. The Small Cap Fund may invest in companies across all sectors of the economy, but may favor companies in particular sectors or industries at different times. The Small Cap Fund may, from time to time, have significant exposure to one or more sectors of the market. The Small Cap Fund may invest in U.S. dollar-denominated foreign equity securities, including through American Depositary Receipts (“ADRs”) and Global Depositary Receipts (“GDRs”) issued by U.S. depository banks, which are traded on U.S. exchanges. The Small Cap Fund may invest in such securities without limit, but such investments are not expected to exceed 20% of the Fund’s total assets.
The Advisor may invest the Small Cap Fund’s assets in the securities of companies that it believes have a history of growth or that it believes have growth potential. Growth may be measured by factors such as earnings or revenue. The Advisor may invest in the securities of companies with leading competitive positions and management that can achieve sustained growth. Companies with the potential for strong growth may have characteristics such as new products, technologies, distribution channels, strong industry or market positions. Growth stocks may be designated as such and purchased based on the premise that the market will eventually reward a given company’s long‑term earnings growth with a higher stock price when that company’s earnings grow faster than both inflation and the economy in general. In selecting investments for the Fund’s portfolio, the Advisor uses fundamental research to evaluate each company, focusing on the company’s earnings growth, return on equity, margin stability, and capital management. These and other factors are then weighed against valuation. A stock may be sold, among other reasons, if it has reached a price target, the issuer’s fundamental outlook has changed, or a better investment opportunity is available.

The following bar chart and table provide some indication of the risks of investing in the Fund. The bar chart below only illustrates how Institutional Class shares of the Fund’s total returns have varied from one calendar year to another over the past 10 years. The returns for the Fund’s Retail Class shares, both before and after taxes, may be lower than the returns shown in the bar chart below for the Institutional Class shares of the Fund, depending on the fees and expenses of the Retail Class shares. The table below illustrates how the Fund’s average annual total returns for the 1-year, 5-year and 10-year periods compare with those of a broad measure of market performance. The returns shown in the bar chart and table include reinvestment of all dividends and capital gains distributions and reflect fund expenses.

The Expense Cap is indefinite, and will remain in effect until at least February 28, 2025. The Agreement may be terminated at any time by the Board of Trustees upon 60 days’ written notice to the Advisor, or by the Advisor with the consent of the Board. The Advisor is permitted, with Board approval, to be reimbursed for fee reductions and/or expense payments made in the prior three years from the date the fees were waived and/or expenses were paid. This reimbursement may be requested if the amount actually paid by the Fund toward operating expenses for such period (taking into account any reimbursement) does not exceed the lesser of the Expense Cap in place at the time of waiver or at the time of reimbursement. The Small Cap Fund’s net operating expenses may be higher to the extent that the Fund incurs expenses that are excluded from the Expense Cap.
