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.</li></ul><ul><li><i>Non-U. S. Securities Risk</i> 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.</li></ul><ul><li><i>Interest Rate Risk</i> The value of debt securities tends to decrease when nominal interest rates rise. Longer-duration securities tend to be more sensitive to interest rate changes, and thus more volatile, than shorter-duration securities.</li></ul><ul><li><i>Credit Risk</i> Changing economic conditions may adversely affect an obligated entity’s actual or perceived ability to pay interest or principal on a fixed income security when due, which in turn can adversely affect the price of or income derived from the security.</li></ul><ul><li><i>Allocation Risk</i> The allocation techniques and decisions of the investment adviser may not produce the desired results.</li></ul><ul><li><i> U.S. Government Securities Risk</i> U.S. government securities that are not issued or guaranteed by the U.S. Treasury are generally more susceptible to loss than are securities that are so issued or guaranteed.</li></ul><ul><li><i>Mortgage Risk</i> Mortgage related securities tend to become more sensitive to interest rate changes as interest rates rise, increasing their volatility. When interest rates decline, underlying borrowers may pay off their loans sooner than expected, forcing the fund to reinvest disposition proceeds at lower prevailing interest rates.</li></ul><ul><li><i>Reinvestment Risk</i> Income from the Fund’s investments may decline if the Fund is forced to invest the proceeds from matured, called or otherwise disposed of debt securities or convertible securities at interest rates that are below the Fund’s earnings rate at that time.</li></ul><ul><li><i>Growth Securities Risk</i> 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.</li></ul><ul><li><i> Small- and Medium-Sized Capitalization Company Risk</i> 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.</li></ul><ul><li><i> Value Securities Risk</i> 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.</li></ul><p>As with all mutual funds, investors may lose money by investing in the Balanced Fund.</p><p>The foregoing descriptions are only summaries.

The performance table is intended to provide some indication of the risks of investment in the Balanced Fund by showing how the Balanced Fund’s average annual total returns compare with the returns of a broad-based securities market index and a performance average of other similar mutual funds, each over a one-year, five-year and ten-year period. After-tax returns for Institutional Class and R Class shares will vary. After-tax returns are estimated using the highest historical individual federal marginal income tax rates and do not reflect the effect of local, state or foreign taxes. Actual after-tax returns will depend on a shareholder’s own tax situation and may differ from those shown. After-tax returns may not be relevant to shareholders who hold their shares through tax-deferred arrangements (such as 401(k) plans and individual retirement accounts). As with all mutual funds, past performance (before and after taxes) is not necessarily an indication of future performance.falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringIf the Fund has annual returns for at least one calendar year, provide a table showing the Fund's (A) average annual total return; (B) average annual total return (after taxes on distributions); and (C) average annual total return (after taxes on distributions and redemption). A Money Market Fund should show only the returns described in clause (A) of the preceding sentence. All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement. The table also shouldshow the returns of an appropriate broadbased securities market index as defined in Instruction 5 to Item 22(b)(7) for the same periods. A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____). For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: 1 -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Paragraph 2 -Subparagraph iv -Subsection b falsefalsePerformance Table Narrative28false0rr_AverageAnnualReturnCaptionrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalse1falsetruefalse00Periods ended December 31, 2010falsefalsefalsefalsefalseOtherxbrli:stringItemTypestringThis item represents Average Anuual Total Returns.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. 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 __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

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.</li></ul><ul><li><i>Non-U.S. Securities Risk</i> 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.</li></ul><ul><li><i> Growth Securities Risk</i> 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.</li></ul><ul><li><i> Small-and Medium-Sized Capitalization Company Risk</i> 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.</li></ul><p>As with all mutual funds, investors may lose money by investing in the Growth Fund.</p><p>The foregoing descriptions are only summaries.

The performance table is intended to provide some indication of the risks of investment in the Growth Fund by showing how the Growth Fund’s average annual total returns compare with the returns of a broad-based securities market index and a performance average of other similar mutual funds over a one-year, five-year and ten-year period. After-tax returns are estimated using the highest historical individual federal marginal income tax rates and do not reflect the effect of local, state or foreign taxes. Actual after-tax returns will depend on a shareholder’s own tax situation and may differ from those shown. After-tax returns may not be relevant to shareholders who hold their shares through tax-deferred arrangements (such as 401(k) plans and individual retirement accounts). As with all mutual funds, past performance (before and after taxes) is not necessarily an indication of future performance.falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringIf the Fund has annual returns for at least one calendar year, provide a table showing the Fund's (A) average annual total return; (B) average annual total return (after taxes on distributions); and (C) average annual total return (after taxes on distributions and redemption). A Money Market Fund should show only the returns described in clause (A) of the preceding sentence. All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement. The table also shouldshow the returns of an appropriate broadbased securities market index as defined in Instruction 5 to Item 22(b)(7) for the same periods. A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____). For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: 1 -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Paragraph 2 -Subparagraph iv -Subsection b falsefalsePerformance Table Narrative57false0rr_AverageAnnualReturnCaptionrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalse1falsetruefalse00Periods ended December 31, 2010falsefalsefalsefalsefalseOtherxbrli:stringItemTypestringThis item represents Average Anuual Total Returns.

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.

The Lipper Multi-Cap Growth Funds Average is a total return performance average of the mutual funds tracked by Lipper, Inc. that, by portfolio practice, invest at least 75% of their equity assets in any one market capitalization range over an extended period of time. Multi-Cap Growth Funds typically have an above-average price-to-earnings ratio, price-to-book ratio, and three-year sales per-share growth value, compared to the S&P Super Composite 1500 Index. The Lipper Multi-Cap Growth Funds Index is not what is typically considered to be an "index" because it tracks the performance of other mutual funds rather than the changes in the value of a group of securities, a securities index or some other traditional economic indicator.</i>67Average Annual Total Returns Pax World Growth FundUnKnownUnKnownUnKnownUnKnownfalsetrueColumnprimaryElement*RowperiodPeriod*Rowdei_DocumentInformationDocumentAxisAxis*Rowrr_PerformanceMeasureAxisAxis*Rowrr_ProspectusShareClassAxisAxis*RowunitUnit*falsefalsefalseOtherus-types:textBlockItemTypestringContains a command for the SEC Viewer for the role corresponding to PerformanceTableData.No authoritative reference available.falsefalsePerformance [Table]59false0natruenanaNo definition available.falsetruefalsefalsefalsefalsefalsefalsefalsefalsehttp://esgmanagers.com/role/riskreturnsummarypaxworldportfolio1falsefalsefalse00Pax World Small Cap FundPax World Small Cap Fundfalsefalsefalsefalsefalse3falsefalsetruefalse{dei_DocumentInformationDocumentAxis} : Pax World Small Cap Fund 5/2/2010 - 5/1/2011 TwelveMonthsEnded_01May2011_S000021459_Memberhttp://www.sec.gov/CIK0000076721duration2010-05-02T00:00:002011-05-01T00:00:00falsefalsepwfst76721_S000021459Memberdei_DocumentInformationDocumentAxisxbrldihttp://xbrl.org/2006/xbrldipwfst76721_S000021459Memberdei_DocumentInformationDocumentAxisexplicitMemberPureStandardhttp://www.xbrl.org/2003/instancepurexbrli0OthernaNo definition available.No authoritative reference available.falsefalsePax World Small Cap Fund61false0rr_RiskReturnHeadingrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00<p>Pax World Small Cap Fund</p><p>(the “Small Cap Fund”)</p><p> Summary of Key Information</p>falsefalsefalsefalsefalseOtherxbrli:stringItemTypestringRisk/Return Summary Investment Objectives/Goals Include the following information, in plain English under rule 421(d) under the Securities Act, in the order and subject matter indicatedReference 1: 1 -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 2 falsefalseRisk/Return [Heading]62false0rr_ObjectiveHeadingrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00Investment ObjectivefalsefalsefalsefalsefalseOtherxbrli:stringItemTypestringInvestment Objectives/Goals.

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.</li></ul><ul><li><i>Non-U. S. Securities Risk</i> 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.</li></ul><ul><li><i> Turnover Risk</i> 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.</li></ul><ul><li><i>Growth Securities Risk</i> 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.</li></ul><ul><li><i>Small-and Medium-Sized Capitalization Company Risk</i> 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.</li></ul><ul><li><i> Value Securities Risk</i> 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.

Actual after-tax returns will depend on a shareholder’s own tax situation and may differ from those shown. After-tax returns may not be relevant to shareholders who hold their shares through tax-deferred arrangements (such as 401(k) plans and individual retirement accounts). As with all mutual funds, past performance (before and after taxes) is not necessarily an indication of future performance.falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringIf the Fund has annual returns for at least one calendar year, provide a table showing the Fund's (A) average annual total return; (B) average annual total return (after taxes on distributions); and (C) average annual total return (after taxes on distributions and redemption). A Money Market Fund should show only the returns described in clause (A) of the preceding sentence. All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement. The table also shouldshow the returns of an appropriate broadbased securities market index as defined in Instruction 5 to Item 22(b)(7) for the same periods. A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____). For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: 1 -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Paragraph 2 -Subparagraph iv -Subsection b falsefalsePerformance Table Narrative86false0rr_AverageAnnualReturnCaptionrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalse1falsetruefalse00Periods ended December 31, 2010falsefalsefalsefalsefalseOtherxbrli:stringItemTypestringThis item represents Average Anuual Total Returns.

Small-Cap Core Funds Index1<i>The Fund's inception date is March 27, 2008. The Fund's 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 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.</i>2<i>The Russell 2000 Index measures the performance of the small-cap segment of the U.S. equity universe. The Russell 2000 Index is a subset of the Russell 3000 Index representing approximately 10% of the total market capitalization of that index. It includes approximately 2000 of the smallest securities based on a combination of their market cap and current index membership.</i>3<i>Unlike the Small Cap Fund, the Russell 2000 Index and the Lipper Small-Cap Core Funds Index are not investments, are not professionally managed, have no policy of sustainable investing and (with the exception of the Lipper Small-Cap Core Funds Index) do not reflect deductions for fees, expenses or taxes.</i>4<i>The Lipper Small-Cap Core Funds Index tracks the results of the 30 largest mutual funds in the Lipper Small-Cap Core Funds Average. The Lipper Small-Cap Core Funds Average is a total return performance average of the mutual funds tracked by Lipper, Inc. that, by portfolio practice, invest at least 75% of their equity assets in companies with market capitalizations (on a three-year weighted basis) below Lipper's USDE small-cap ceiling. Small-cap core funds have more latitude in the companies in which they invest. These funds typically have an average price-to-earnings ratio, price-to-book ratio, and three-year sales-per-share growth value, compared to the S&P SmallCap 600 Index. The Lipper Small-Cap Core Funds Index is not what is typically considered to be an "index" because it tracks the performance of other mutual funds rather than the changes in the value of a group of securities, a securities index or some other traditional economic indicator.</i>57Average Annual Total Returns Pax World Small Cap FundUnKnownUnKnownUnKnownUnKnownfalsetrueColumnprimaryElement*RowperiodPeriod*Rowdei_DocumentInformationDocumentAxisAxis*Rowrr_PerformanceMeasureAxisAxis*Rowrr_ProspectusShareClassAxisAxis*RowunitUnit*falsefalsefalseOtherus-types:textBlockItemTypestringContains a command for the SEC Viewer for the role corresponding to PerformanceTableData.No authoritative reference available.falsefalsePerformance [Table]88false0natruenanaNo definition available.falsetruefalsefalsefalsefalsefalsefalsefalsefalsehttp://esgmanagers.com/role/riskreturnsummarypaxworldportfolio1falsefalsefalse00Pax World International FundPax World International Fundfalsefalsefalsefalsefalse4falsefalsetruefalse{dei_DocumentInformationDocumentAxis} : Pax World International Fund 5/2/2010 - 5/1/2011 TwelveMonthsEnded_01May2011_S000015760_Memberhttp://www.sec.gov/CIK0000076721duration2010-05-02T00:00:002011-05-01T00:00:00falsefalsepwfst76721_S000015760Memberdei_DocumentInformationDocumentAxisxbrldihttp://xbrl.org/2006/xbrldipwfst76721_S000015760Memberdei_DocumentInformationDocumentAxisexplicitMemberPureStandardhttp://www.xbrl.org/2003/instancepurexbrli0OthernaNo definition available.No authoritative reference available.falsefalsePax World International Fund90false0rr_RiskReturnHeadingrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00<p>Pax World International Fund</p><p>(the “International Fund”)</p><p>Summary of Key Information</p>falsefalsefalsefalsefalseOtherxbrli:stringItemTypestringRisk/Return Summary Investment Objectives/Goals Include the following information, in plain English under rule 421(d) under the Securities Act, in the order and subject matter indicatedReference 1: 1 -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 2 falsefalseRisk/Return [Heading]91false0rr_ObjectiveHeadingrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00Investment ObjectivefalsefalsefalsefalsefalseOtherxbrli:stringItemTypestringInvestment Objectives/Goals.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. 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 __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

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.</li></ul><ul><li><i>Non-U. S. Securities Risk</i> 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.</li></ul><ul><li><i>Growth Securities Risk</i> 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.</li></ul><ul><li><i>Small-and Medium-Sized Capitalization Company Risk</i> 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.</li></ul><ul><li><i> Value Securities Risk</i> 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.

International Large-Cap Core Funds Index1<i>The Fund's inception date is March 27, 2008. The Fund's 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 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.</i>2<i>The MSCI EAFE (Europe, Australasia, Far East) Index is a free float-adjusted market capitalization index that is designed to measure the equity market performance of developed markets, excluding the U.S. and Canada. As of July 2010 the MSCI EAFE Index consisted of the following 22 developed market country indices: Australia, Austria, Belgium, Denmark, Finland, France, Germany, Greece, Hong Kong, Ireland, Israel, Italy, Japan, the Netherlands, New Zealand, Norway, Portugal, Singapore, Spain, Sweden, Switzerland, and the United Kingdom. Performance for the MSCI EAFE Index is shown "net", which includes dividend reinvestments after deduction of foreign withholding tax.</i>3<i>The Lipper International Large-Cap Core Funds Index tracks the results of the 30 largest mutual funds in the Lipper International Large-Cap Core Funds Average. The Lipper International Large-Cap Core Funds Average is a total return performance average of the mutual funds tracked by Lipper, Inc. that, by portfolio practice, invest at least 75% of their equity assets in companies strictly outside of the U.S. with market capitalizations (on a three-year weighted basis) above Lipper's international large-cap floor. International large-cap core funds typically have an average price-to-cash flow ratio, price-to-book ratio, and three-year sales-per-share growth value compared to their large-cap-specific subset of the S&P/Citigroup World ex-U.S. BMI. The Lipper International Large-Cap Core Funds Index is not what is typically considered to be an "index" because it tracks the performance of other mutual funds rather than the changes in the value of a group of securities, a securities index, or some other traditional economic indicator.</i>4<i>Unlike the International Fund, the MSCI EAFE (Net) Index and the Lipper International Large-Cap Core Funds Index are not investments, are not professionally managed, have no policy of sustainable investing and (with the exception of the Lipper International Large-Cap Core Funds Index) do not reflect deductions for fees, expenses or taxes.</i>57Average Annual Total Returns Pax World International FundUnKnownUnKnownUnKnownUnKnownfalsetrueColumnprimaryElement*RowperiodPeriod*Rowdei_DocumentInformationDocumentAxisAxis*Rowrr_PerformanceMeasureAxisAxis*Rowrr_ProspectusShareClassAxisAxis*RowunitUnit*falsefalsefalseOtherus-types:textBlockItemTypestringContains a command for the SEC Viewer for the role corresponding to PerformanceTableData.No authoritative reference available.falsefalsePerformance [Table]117false0natruenanaNo definition available.falsetruefalsefalsefalsefalsefalsefalsefalsefalsehttp://esgmanagers.com/role/riskreturnsummarypaxworldportfolio1falsefalsefalse00Pax World High Yield Bond FundPax World High Yield Bond Fundfalsefalsefalsefalsefalse5falsefalsetruefalse{dei_DocumentInformationDocumentAxis} : Pax World High Yield Bond Fund 5/2/2010 - 5/1/2011 TwelveMonthsEnded_01May2011_S000015758_Memberhttp://www.sec.gov/CIK0000076721duration2010-05-02T00:00:002011-05-01T00:00:00falsefalsepwfst76721_S000015758Memberdei_DocumentInformationDocumentAxisxbrldihttp://xbrl.org/2006/xbrldipwfst76721_S000015758Memberdei_DocumentInformationDocumentAxisexplicitMemberPureStandardhttp://www.xbrl.org/2003/instancepurexbrli0OthernaNo definition available.No authoritative reference available.falsefalsePax World High Yield Bond Fund119false0rr_RiskReturnHeadingrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00<p>Pax World High Yield Bond Fund</p><p>(the “High Yield Bond Fund”)</p><p>Summary of Key Information</p>falsefalsefalsefalsefalseOtherxbrli:stringItemTypestringRisk/Return Summary Investment Objectives/Goals Include the following information, in plain English under rule 421(d) under the Securities Act, in the order and subject matter indicatedReference 1: 1 -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 2 falsefalseRisk/Return [Heading]120false0rr_ObjectiveHeadingrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00Investment ObjectivesfalsefalsefalsefalsefalseOtherxbrli:stringItemTypestringInvestment Objectives/Goals.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. 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 __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

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.</li></ul> <ul><li><i> Non-U. S. Securities Risk</i> 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.</li></ul> <ul><li><i>Interest Rate Risk</i> The value of debt securities tends to decrease when nominal interest rates rise. Longer-duration securities tend to be more sensitive to interest rate changes, and thus more volatile, than shorter-duration securities.</li></ul> <ul><li><i>Credit Risk </i> Changing economic conditions may adversely affect an obligated entity’s actual or perceived ability to pay interest or principal on a fixed income security when due, which in turn can adversely affect the price of or income derived from the security.</li></ul> <ul><li><i>Reinvestment Risk</i> Income from the Fund’s investments may decline if the Fund is forced to invest the proceeds from matured, called or otherwise disposed of debt securities or convertible securities at interest rates that are below the Fund’s earnings rate at that time.</li></ul> <ul><li><i>Small-and Medium-Sized Capitalization Company Risk </i> 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.</li></ul> <ul><li><i>High Yield Securities Risk </i> High yield securities (“junk bonds”) are considered predominately speculative with respect to the issuer’s continuing ability to make principal and interest payments when due.

The performance table is intended to provide some indication of the risks of investment in the High Yield Bond Fund by showing how the High Yield Bond Fund’s average annual total returns compare with the returns of a broad-based securities market index and a performance average of other similar mutual funds, each over a one-year, five-year and ten-year period. After-tax returns for Institutional Class and R Class shares will vary. After-tax returns are estimated using the highest historical individual federal marginal income tax rates and do not reflect the effect of local, state or foreign taxes. Actual after-tax returns will depend on a shareholder’s own tax situation and may differ from those shown. After-tax returns may not be relevant to shareholders who hold their shares through tax-deferred arrangements (such as 401(k) plans and individual retirement accounts). As with all mutual funds, past performance (before and after taxes) is not necessarily an indication of future performance.falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringIf the Fund has annual returns for at least one calendar year, provide a table showing the Fund's (A) average annual total return; (B) average annual total return (after taxes on distributions); and (C) average annual total return (after taxes on distributions and redemption). A Money Market Fund should show only the returns described in clause (A) of the preceding sentence. All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement. The table also shouldshow the returns of an appropriate broadbased securities market index as defined in Instruction 5 to Item 22(b)(7) for the same periods. A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____). For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: 1 -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Paragraph 2 -Subparagraph iv -Subsection b falsefalsePerformance Table Narrative145false0rr_AverageAnnualReturnCaptionrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalse1falsetruefalse00Periods ended December 31, 2010falsefalsefalsefalsefalseOtherxbrli:stringItemTypestringThis item represents Average Anuual Total Returns.

High Current Yield Bond Funds Index1<i>The Fund's 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 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 800.767.1729.</i>2<i>Inception of Institutional Class shares is June 1, 2004. The performance information shown for Institutional Class shares includes the performance of Individual Investor Class shares for the period prior to Institutional Class inception. Expenses have not been adjusted to reflect the expenses allocable to Institutional Class shares. If such expenses were reflected, the returns would be higher than those shown.</i>3<i>Inception of R Class shares is April 2, 2007. The performance information shown for R Class shares includes the performance of Individual Investor Class shares for the period prior to R Class inception. Expenses have not been adjusted to reflect the expenses allocable to R Class shares. If such expenses were reflected, the returns would be lower than those shown.</i>4<i>The BofA Merrill Lynch U.S. High Yield BB-B (Constrained 2%) Index tracks the performance of BB- and B-rated fixed income securities publicly issued in the major domestic or eurobond markets, with total index allocation to an individual issuer limited to 2%. The benchmark of High Yield Bond Fund was changed to the BofA Merrill Lynch U.S. High Yield BB-B (Constrained 2%) Index effective June 30, 2010. Pax World believes the BofA Merrill Lynch U.S. High Yield BB-B (Constrained 2%) Index more closely corresponds to the investments of the Fund.</i>5<i>Unlike the High Yield Bond Fund, the BofA Merrill Lynch U.S. High Yield BB-B (Constrained 2%) Index, the BofA Merrill Lynch High Yield Master I Index and the Lipper High Current Yield Bond Funds Index are not investments, are not professionally managed, have no policy of sustainable investing and (with the exception of the Lipper High Current Yield Bond Funds Index) do not reflect deductions for fees, expenses or taxes.</i>6<i>The BofA Merrill Lynch High Yield Master I Index tracks the performance of below investment grade U.S. dollar-denominated corporate bonds publicly issued in the U.S. domestic market.</i>7<i>The Lipper High Current Yield Bond Funds Index tracks the results of the 30 largest mutual funds in the Lipper High Current Yield Bond Funds Average. The Lipper High Current Yield Bond Funds Average is a total return performance average of mutual funds tracked by Lipper, Inc. that aim at high (relative) current yield from fixed income securities, have no quality or maturity restrictions and tend to invest in lower grade debt issues. The Lipper High Current Yield Bond Funds Index is not what is typically considered an "index" because it tracks the performance of other mutual funds rather than changes in the value of a group of securities, a securities index or some other traditional economic indicator.</i>68Average Annual Total Returns Pax World High Yield Bond FundUnKnownUnKnownUnKnownUnKnownfalsetrueColumnprimaryElement*RowperiodPeriod*Rowdei_DocumentInformationDocumentAxisAxis*Rowrr_PerformanceMeasureAxisAxis*Rowrr_ProspectusShareClassAxisAxis*RowunitUnit*falsefalsefalseOtherus-types:textBlockItemTypestringContains a command for the SEC Viewer for the role corresponding to PerformanceTableData.No authoritative reference available.falsefalsePerformance [Table]147false0natruenanaNo definition available.falsetruefalsefalsefalsefalsefalsefalsefalsefalsehttp://esgmanagers.com/role/riskreturnsummarypaxworldportfolio1falsefalsefalse00Pax World Global Women's Equality FundPax World Global Women's Equality Fundfalsefalsefalsefalsefalse6falsefalsetruefalse{dei_DocumentInformationDocumentAxis} : Pax World Global Women's Equality Fund 5/2/2010 - 5/1/2011 TwelveMonthsEnded_01May2011_S000019419_Memberhttp://www.sec.gov/CIK0000076721duration2010-05-02T00:00:002011-05-01T00:00:00falsefalsepwfst76721_S000019419Memberdei_DocumentInformationDocumentAxisxbrldihttp://xbrl.org/2006/xbrldipwfst76721_S000019419Memberdei_DocumentInformationDocumentAxisexplicitMemberPureStandardhttp://www.xbrl.org/2003/instancepurexbrli0OthernaNo definition available.No authoritative reference available.falsefalsePax World Global Women's Equality Fund149false0rr_RiskReturnHeadingrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00<p>Pax World Global Women's Equality Fund</p><p>(the “Women’s Equality Fund”)</p><p>Summary of Key Information</p>falsefalsefalsefalsefalseOtherxbrli:stringItemTypestringRisk/Return Summary Investment Objectives/Goals Include the following information, in plain English under rule 421(d) under the Securities Act, in the order and subject matter indicatedReference 1: 1 -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 2 falsefalseRisk/Return [Heading]150false0rr_ObjectiveHeadingrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00Investment ObjectivefalsefalsefalsefalsefalseOtherxbrli:stringItemTypestringInvestment Objectives/Goals.

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.</li></ul><ul><li><i>Non-U. S. Securities Risk </i> 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</li></ul><ul><li><i>Turnover Risk </i> 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.</li></ul><ul><li><i>Growth Securities Risk </i> 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.</li></ul><ul><li><i>Small-and Medium-Sized Capitalization Company Risk</i> 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.</li></ul><ul><li><i>Value Securities Risk </i> 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.</li></ul> <p>As with all mutual funds, investors may lose money by investing in the Women’s Equality Fund.</p><p>The foregoing descriptions are only summaries.

Cap Core Funds Index1<i>Pax World Global Women's Equality Fund, a series of Pax World Funds Series Trust I, acquired Women's Equity Fund, a series of Professionally Managed Portfolios ("Old Women's Equity Fund" ), on October 29, 2007. Performance information shown includes the performance of Retail Class shares of Old Women's Equity Fund for periods prior to October 29, 2007, which has not been adjusted to reflect any differences in expenses between Old Women's Equity Fund and the Global Women's Equality Fund; if such expense adjustments were reflected, the returns would be higher than those shown. The Fund's 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 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 800.767.1729.</i>2<i>Inception of Institutional Class shares is April 19, 2006. The performance information shown for Institutional Class shares includes the performance of the Retail Class shares of Old Women's Equity Fund shares for the period prior to Institutional Class inception. Expenses have not been adjusted to reflect the expenses allocable to Institutional Class shares or to reflect any differences in expenses between Old Women's Equity Fund and the Global Women's Equality Fund. If such expense adjustments and allocable expenses were reflected, the returns would be higher than those shown.</i>3<i>The MSCI World Large Cap Index is a subset of the MSCI World Index, and has a target coverage range of approximately 70% of the free float-adjusted market capitalization within the MSCI World Index. The MSCI World Index is a free float-adjusted market capitalization-weighted index that is designed to measure the equity market performance of developed markets. As of May 2010, the MSCI World Index consisted of the following 24 developed market country indices: Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Greece, 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 Large Cap Index is shown "net," which includes dividend reinvestments after deduction of foreign withholding taxes.</i>4<i>Unlike the Global Women's Equality Fund, the MSCI World Large Cap (Net) Index and the Lipper Global Large-Cap Core Funds Index are not investments, are not professionally managed, have no policy of sustainable investing and (with the exception of the Lipper Global Large-Cap Core Funds Index) do not reflect deductions for fees, expenses or taxes.</i>5<i>The Lipper Global Large-Cap Core Funds Index tracks the results of the 30 largest mutual funds in the Lipper Global Large-Cap Funds Average. The Lipper Global Large-Cap Funds Average is a total return performance average of the mutual funds tracked by Lipper, Inc. that, by portfolio practice, invest at least 75% of their equity assets in companies both inside and outside of the U.S. with market capitalizations (on a three year weighted basis) above Lipper's Global Large-Cap floor. Global Large-Cap Core funds typically have an average price-to-cash flow ratio, price-to-book ratio, and three-year sales-per-share growth value compared to their large-cap-specific subset of the S&P/Citigroup World BMI. The Lipper Global Large-Cap Core Funds Index is not what is typically considered to be an "index" because it tracks the performance of other mutual funds rather than changes in the value of a group of securities, a securities index or some other traditional economic indicator.</i>66Average Annual Total Returns Pax World Global Women's Equality FundUnKnownUnKnownUnKnownUnKnownfalsetrueColumnprimaryElement*RowperiodPeriod*Rowdei_DocumentInformationDocumentAxisAxis*Rowrr_PerformanceMeasureAxisAxis*Rowrr_ProspectusShareClassAxisAxis*RowunitUnit*falsefalsefalseOtherus-types:textBlockItemTypestringContains a command for the SEC Viewer for the role corresponding to PerformanceTableData.No authoritative reference available.falsefalsePerformance [Table]176false0natruenanaNo definition available.falsetruefalsefalsefalsefalsefalsefalsefalsefalsehttp://esgmanagers.com/role/riskreturnsummarypaxworldportfolio1falsefalsefalse00Pax World Global Green FundPax World Global Green Fundfalsefalsefalsefalsefalse7falsefalsetruefalse{dei_DocumentInformationDocumentAxis} : Pax World Global Green Fund 5/2/2010 - 5/1/2011 TwelveMonthsEnded_01May2011_S000021458_Memberhttp://www.sec.gov/CIK0000076721duration2010-05-02T00:00:002011-05-01T00:00:00falsefalsepwfst76721_S000021458Memberdei_DocumentInformationDocumentAxisxbrldihttp://xbrl.org/2006/xbrldipwfst76721_S000021458Memberdei_DocumentInformationDocumentAxisexplicitMemberPureStandardhttp://www.xbrl.org/2003/instancepurexbrli0OthernaNo definition available.No authoritative reference available.falsefalsePax World Global Green Fund178false0rr_RiskReturnHeadingrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00<p>Pax World Global Green Fund</p><p>(the “Global Green Fund”)</p><p> Summary of Key Information</p>falsefalsefalsefalsefalseOtherxbrli:stringItemTypestringRisk/Return Summary Investment Objectives/Goals Include the following information, in plain English under rule 421(d) under the Securities Act, in the order and subject matter indicatedReference 1: 1 -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 2 falsefalseRisk/Return [Heading]179false0rr_ObjectiveHeadingrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00Investment ObjectivefalsefalsefalsefalsefalseOtherxbrli:stringItemTypestringInvestment Objectives/Goals.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. 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 __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

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.</li></ul><ul><li><i>Non-U. S. Securities Risk</i> 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.</li></ul><ul><li><i>Turnover Risk</i> 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.</li></ul><ul><li><i>Growth Securities Risk</i> 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. the values of other securities.</li></ul><ul><li><i>Small-and Medium-Sized Capitalization Company Risk </i> 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.</li></ul><ul><li><i>Value Securities Risk</i> 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.

The Fund's 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 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.</i>2<i>The MSCI World Index is a free float-adjusted market capitalization weighted index that is designed to measure the equity market performance of developed markets. As of May 2010 the MSCI World (Net) Index consisted of the following 24 developed market country indices: Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Greece, 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.</i>3<i>Unlike the Global Green 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.</i>4<i>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 and waste and pollution control. 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 Green Fund.</i>57Average Annual Total Returns Pax World Global Green FundUnKnownUnKnownUnKnownUnKnownfalsetrueColumnprimaryElement*RowperiodPeriod*Rowdei_DocumentInformationDocumentAxisAxis*Rowrr_PerformanceMeasureAxisAxis*Rowrr_ProspectusShareClassAxisAxis*RowunitUnit*falsefalsefalseOtherus-types:textBlockItemTypestringContains a command for the SEC Viewer for the role corresponding to PerformanceTableData.No authoritative reference available.falsefalsePerformance [Table]1196Risk/Return Summary - Pax World PortfolioUnKnownUnKnownUnKnownUnKnownfalsetrue
