Portfolio Turnover

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 shares are held in a taxable account. These transaction costs, which are not reflected in "Annual Fund Operating Expenses" or in the "Example of Expenses," affect the Global Environmental Markets Fund's performance. During the Global Environmental Markets Fund's most recent fiscal year, the Global Environmental Markets Fund's portfolio turnover rate was 27% of the average value of its portfolio.

Expense Example Narrative [Text Block]

This example is intended to help you compare the cost of investing in Institutional Class, Individual Investor Class, Class A and Class R shares of the Global Environmental Markets Fund with the cost of investing in other mutual funds.

The table assumes that an investor invests $10,000 in Institutional Class, Individual Investor Class, Class A or Class R shares of the Global Environmental Markets Fund for the time periods indicated and then redeems all of his or her shares at the end of those periods. The table also assumes that the investment has a 5% return each year, that all dividends and distributions are reinvested and that the Global Environmental Markets Fund's operating expenses remain the same throughout those periods. Although an investor's actual expenses may be higher or lower than those shown in the table, based on these assumptions his or her expenses would be:

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Global Environmental Markets Fund follows a sustainable investing approach, combining rigorous financial analysis with equally rigorous environmental, social and governance (ESG) analysis in order to identify investments. Under normal market conditions, the Global Environmental Markets Fund will invest primarily in equity securities (such as common stocks, preferred stocks and securities convertible into common and preferred stocks) of companies located around the world, including at least 40% of its net assets in securities of non-U.S. issuers, including those located in emerging markets. The Fund's investments may be diversified across multiple countries or geographic regions, or may be focused on a select geographic region, although the Global Environmental Markets Fund will normally have investments in a minimum of three countries other than the United States.

The Global Environmental Markets Fund invests in environmental markets—companies whose businesses and technologies focus on environmental markets, including alternative energy and energy efficiency; water infrastructure technologies and pollution control; environmental support services and waste management technologies; and sustainable food, agriculture and forestry. The Global Environmental Markets Fund's portfolio manager selects equity securities on a company-by-company basis primarily through the use of fundamental analysis. The Global Environmental Markets Fund is not constrained by any particular investment style, and may therefore invest in "growth" stocks, "value" stocks or a combination of both. Additionally, it may buy stocks in any sector or industry, and it is not limited to investing in securities of a specific market capitalization.

The Global Environmental Markets Fund may utilize derivatives for hedging and for investment purposes.

The Global Environmental Markets Fund seeks to invest in companies with positive overall environmental performance and whose products or services help other companies and countries improve their environmental performance, and avoids investing in companies with significant environmental problems or worsening environmental profiles. In addition, the Fund strives to be fossil fuel-free (avoiding investing in companies that PWM determines are significantly involved in the extraction and/or refining of fossil fuels).

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

• Market Risk Conditions in a broad or specialized market, a sector thereof or an individual industry may adversely affect security prices, thereby reducing the value of the Fund's investments.

• Derivatives Risk Derivatives involve special risks and may result in losses. The values of derivatives can be very volatile, especially in unusual market conditions, and that volatility can be exacerbated by the use of leverage, which is common for derivative strategies. Derivatives may be illiquid, and may also be subject to the risk of nonperformance by a transaction counterparty. The Fund may not be able to enter into, or terminate, a derivatives position when desired. Derivatives are also subject to mispricing and improper valuation, and may increase the amount of taxes payable by shareholders.

• Non-U. S. Securities Risk Non-U.S. securities may have less liquidity and more volatile prices than domestic securities, which can make it difficult for the Fund to sell such securities at desired times or prices. Non-U.S. markets may differ from U.S. markets in material and adverse ways. For example, securities transaction expenses generally are higher, transaction settlement may be slower, recourse in the event of default may be more limited and taxes and currency exchange controls may limit amounts available for distribution to shareholders. Non-U.S. investments are also subject to the effects of local political, social, diplomatic or economic events.

• Turnover Risk Frequent changes in the securities held by a Fund increases the Fund's transaction costs and may result in adverse tax consequences, which together may adversely affect the Fund's performance.

• Growth Securities Risk Growth securities typically trade at higher multiples of current earnings than other securities. Therefore, the values of growth securities may be more sensitive to changes in current or expected earnings than the values of other securities.

• Small- and Medium-Sized Capitalization Company Risk Securities of small- and medium-sized companies may have less liquidity and more volatile prices than securities of larger companies, which can make it difficult for the Fund to sell such securities at desired times or prices.

• Value Securities Risk Value securities are securities the investment adviser believes are selling at a price lower than their true value, perhaps due to adverse business developments or special risks. If that belief is wrong or remains unrecognized by the market, the price of the securities may decline or may not appreciate as anticipated.

As with all mutual funds, investors may lose money by investing in the Global Environmental Markets Fund. The foregoing descriptions are only summaries. Please see "About the Funds—Risks" on page 71 for more detailed descriptions of the foregoing risks.

[1]	Unlike the Global Environmental Markets Fund, the MSCI World (Net) Index and the FTSE Environmental Opportunities Index Series are not investments, are not professionally managed, have no policy of sustainable investing and do not reflect deductions for fees, expenses or taxes. One cannot invest directly in any index.
[2]	The MSCI World (Net) Index is a free float-adjusted market capitalization weighted index that is designed to measure the equity market performance of developed markets. The MSCI World (Net) Index consisted of the following 23 developed market country indices: Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Hong Kong, Ireland, Israel, Italy, Japan, Netherlands, New Zealand, Norway, Portugal, Singapore, Spain, Sweden, Switzerland, the United Kingdom, and the United States. Performance for the MSCI World Index is shown "net", which includes dividend reinvestments after deduction of foreign withholding tax.
[3]	The FTSE Environmental Opportunities Index Series measures the performance of global companies that have significant involvement in environmental business activities, including renewable and alternative energy, energy efficiency, water technology; waste and pollution control; and food, agriculture and forestry. The FTSE Environmental Opportunities Index Series requires companies to have at least 20% of their business derived from environmental markets and technologies. The FTSE Environmental Opportunities Index Series is published by a joint venture of Impax Asset Management, Ltd. ("Impax") with FTSE International. Impax is also the sub-adviser to the Pax World Global Environmental Markets Fund.
[4]	The Fund charges a fee of $10.00 for each wire redemption, subject to change without notice.
[5]	The Global Environmental Markets Fund's investment adviser has contractually agreed to reimburse expenses (excluding Acquired Fund Fees and Expenses, if any) allocable to Institutional Class, Individual Investor Class, Class A and Class R shares of the Global Environmental Markets Fund to the extent such expenses exceed 1.15%, 1.40%, 1.40% and 1.65% of the average daily net assets of Institutional Class, Individual Investor Class, Class A and Class R shares, respectively. This reimbursement arrangement may not be amended or terminated without the approval of the Fund's Board of Trustees before December 31, 2016.
[6]	The Fund's inception date is March 27, 2008. The Fund's investment adviser assumed certain expenses during the period; total returns would have been lower had these expenses not been assumed. Total return figures include reinvested dividends and capital gains distributions, and changes in principal value, and, other than for Individual Investor Class shares, do not reflect the taxes that a shareholder might pay on Fund distributions or on the redemption of Fund shares. These figures represent past performance, which is no guarantee of future results. Investment return and principal value of an investment will fluctuate so that an investor's shares, when redeemed, may be worth more or less than their original cost. Current performance may be lower or higher than the performance data quoted. For more recent month-end performance data, please visit www.paxworld.com or call us at 800.767.1729.
[7]	This charge applies to investors who purchase $1 million or more of Class A shares without an initial sales charge and redeem them within 18 months of purchase, with certain exceptions. See "Shareholder Guide-Sales Charges."
[8]	Inception of Class A shares is May 1, 2013. The performance information shown for Class A shares includes the performance of Individual Investor Class shares, adjusted to reflect the sales charge applicable to Class A shares, for the period prior to Class A inception.
