| 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 year, the Fund’s portfolio turnover rate was 53.57% of the average value of its portfolio.

| Strategy [Heading] | rr_StrategyHeading | Principal Investment Strategies of the Fund | ||||
| Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | Under normal market conditions, the Fund invests primarily in a diversified portfolio of common stocks and other equity securities of companies of all sizes, including but not limited to, American Depositary Receipts (“ADRs”), preferred stocks, limited partnerships, and convertible securities. O’Shaughnessy Asset Management, LLC (the “Adviser”) employs a bottom-up, quantitative, factor-based approach to security selection based on research and analysis of historical data. The Adviser may eliminate or substitute factors at its discretion. Portfolio securities may be sold generally upon periodic rebalancing of the Fund’s portfolio. For selling decisions, the Adviser considers the same factors it uses in evaluating a security for purchase and generally sells securities when it believes such securities no longer meet its investment criteria. The Fund may from time to time emphasize investment in certain sectors of the market. The Adviser screens securities using a factor-based model that seeks to identify market leading companies by analysis of a number of factors including, but not limited to, low valuations, strong financial strength, conservative earnings reporting (earnings quality), strong earnings growth, market capitalization and volume. The Fund selects companies that offer a strong “shareholder yield” – the combination of dividend yield and the rate at which the company is buying back shares of its stock – at the time of initial purchase. While stocks often have both a strong dividend yield and a high rate of share repurchases, that may not always be the case. An individual stock may be deemed to be attractive even if its entire shareholder yield is generated from either dividends or share repurchases. Due to ongoing research, the Adviser may modify the characteristics utilized in the investment strategy, without prior notice to shareholders, in order to better achieve the investment objective. The Fund will primarily invest in common stocks of U.S. issuers but may also invest up to 20% of its total assets in common stocks of foreign securities and issuers, which may also include issuers located in emerging markets and frontier markets, also known as “pre-emerging markets,” as defined by countries listed on the Morgan Stanley Capital International (“MSCI”) Emerging Markets Index and/or the MSCI Frontier Markets Index. The Fund may invest up to 25% of its total assets in REITs or foreign real estate companies. The Fund may also invest up to 20% of its total assets in depositary receipts of foreign based companies (i.e., ADRs, European Depositary Receipts (“EDRs”), and Global Depositary Receipts (“GDRs”), etc.) whose common stock is not itself listed on a U.S. exchange. Depositary receipts may be purchased through “sponsored” or “unsponsored” facilities. A sponsored facility is established jointly by the issuer of the underlying security and a depositary, whereas a depositary may establish an unsponsored facility without participation by the issuer of the depositary security. The Fund may invest up to 10% of its total assets in other investment companies, including exchange-traded funds (“ETFs”). The Fund may also invest up to 100% of the Fund’s total assets in cash, cash equivalents, and high-quality, short-term debt securities, money market mutual funds and money market instruments for temporary defensive purposes. The Fund may also invest up to 50% of its total assets in ETFs that are aligned with the Fund’s principal investment strategies, for temporary defensive purposes.

| O'Shaughnessy Market Leaders Value Fund | Equity Securities Risk [Text Block] | ||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||
| Risk Narrative [Text Block] | rr_RiskTextBlock | Equity Securities Risk. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. The values of convertible securities tend to decline as interest rates rise and, because of the conversion feature, tend to vary with fluctuations in the market value of the underlying equity security. | ||||
| O'Shaughnessy Market Leaders Value Fund | General Market Risk Member | ||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||
| Risk Narrative [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 general financial markets, a particular financial market or other asset classes due to a number of factors, including: inflation (or expectations for inflation); deflation (or expectations for deflation); interest rates; market instability; financial system instability; debt crises and downgrades; embargoes; tariffs; sanctions and other trade barriers; regulatory events; other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics. 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 effects 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 recent market volatility and may continue to do so. | ||||
| O'Shaughnessy Market Leaders Value Fund | Value Style Investing Risk Member | ||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||
| Risk Narrative [Text Block] | rr_RiskTextBlock | Value Style Investing Risk. At times when the value investing style is out of favor, the Fund may underperform other funds that use different investing styles. Value stocks may be purchased based upon the belief that a given security may be out of favor; that belief may be misplaced or the security may stay out of favor for an extended period of time. | ||||
| O'Shaughnessy Market Leaders Value Fund | Large-Sized Companies Risk Member | ||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||
| Risk Narrative [Text Block] | rr_RiskTextBlock | Large-Sized Companies Risk. Larger, more established companies may be unable to respond quickly to new competitive challenges like changes in consumer tastes or innovative smaller competitors. In addition, large-cap companies are sometimes unable to attain the high growth rates of successful, smaller companies, especially during extended periods of economic expansion. | ||||
| O'Shaughnessy Market Leaders Value Fund | Small- And Medium-Sized Companies Risk Member | ||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||
| Risk Narrative [Text Block] | rr_RiskTextBlock | Small- and Medium-Sized Companies Risk. Small- and medium-sized companies often have less predictable earnings, more limited product lines, markets, distribution channels or financial resources and the management of such companies may be dependent upon one or few key people. The market movements of equity securities of small- and medium-sized companies may be more abrupt and volatile than the market movements of equity securities of larger, more established companies or the stock market in general and small-sized companies in particular, are generally less liquid than the equity securities of larger companies. | ||||
| O'Shaughnessy Market Leaders Value Fund | Sector Risk Member | ||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||
| Risk Narrative [Text Block] | rr_RiskTextBlock | Sector Risk. To the extent the Fund invests a significant portion of its assets in the securities of companies in the same sector of the market, the Fund is more susceptible to economic, political, regulatory and other occurrences influencing those sectors. | ||||
| O'Shaughnessy Market Leaders Value Fund | REITs And Foreign Real Estate Company Risk Member | ||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||
| Risk Narrative [Text Block] | rr_RiskTextBlock | REITs and Foreign Real Estate Company Risk. Investing in REITs and foreign real estate companies makes the Fund more susceptible to risks associated with the ownership of real estate and with the real estate industry in general, as well as tax compliance risks, and may involve duplication of management fees and other expenses. REITs and foreign real estate companies may be less diversified than other pools of securities, may have lower trading volumes and may be subject to more abrupt or erratic price movements than the overall securities markets. | ||||
| O'Shaughnessy Market Leaders Value Fund | Management Risk Member | ||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||
| Risk Narrative [Text Block] | rr_RiskTextBlock | Management Risk. The Fund is an actively managed portfolio. The Adviser’s management practices and investment strategies might not work to meet the Fund’s investment objective. | ||||
| O'Shaughnessy Market Leaders Value Fund | Depositary Receipts Risk Member | ||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||
| Risk Narrative [Text Block] | rr_RiskTextBlock | Depositary Receipts Risk. The Fund’s equity investments may take the form of sponsored or unsponsored depositary receipts. Holders of unsponsored depositary receipts generally bear all the costs of such facilities and the depositary of an unsponsored facility frequently is under no obligation to distribute shareholder communications received from the issuer of the deposited security or to pass through voting rights to the holders of such receipts of the deposited securities. | ||||
| O'Shaughnessy Market Leaders Value Fund | Foreign Securities And Emerging Markets Risk Member | ||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||
| Risk Narrative [Text Block] | rr_RiskTextBlock | Foreign Securities and Emerging Markets Risk. The risks of investing in the securities of foreign issuers, including depositary receipts, can include fluctuations in foreign currencies, foreign currency exchange controls, political and economic instability, differences in securities regulation and trading, and foreign taxation issues. These risks are greater in emerging markets. | ||||
| O'Shaughnessy Market Leaders Value Fund | Investment Company Risk Member | ||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||
| Risk Narrative [Text Block] | rr_RiskTextBlock | Investment Company Risk. When the Fund invests in an ETF or mutual fund, it will bear additional expenses based on its pro rata share of the ETF’s or mutual fund’s operating expenses, including the potential duplication of management fees. The risk of owning an ETF or mutual fund generally reflects the risks of owning the underlying securities the ETF or mutual fund holds. The Fund also will incur brokerage costs when it purchases ETFs. | ||||
| O'Shaughnessy Market Leaders Value Fund | Frontier Markets Risk Member | ||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | |||||
| Risk Narrative [Text Block] | rr_RiskTextBlock | Frontier Markets Risk. There is an additional increased risk of price volatility associated with frontier market countries (pre-emerging markets), which may be further magnified by currency fluctuations relative to the U.S. dollar. Frontier market countries generally have smaller economies or less developed capital markets than in more advanced emerging markets and, as a result, the risks of investing in emerging market countries may be magnified in frontier market countries. | ||||
