Portfolio Turnover [Text Block]

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 581% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund normally invests at least 80% of its net assets in U.S. government securities and related derivatives. Related derivatives include exchange-traded futures on U.S. Treasury notes and bonds, and options on these futures, and other derivatives intended to hedge interest rate risk, such as swaps, options on swaps, and interest rate caps and floors. The Fund invests mainly in U.S. government bonds. These bonds include direct obligations of the U.S. Treasury, obligations guaranteed by the U.S. government, and obligations of U.S. government agencies and instrumentalities. The Fund is not required, however, to invest set amounts in any of the various types of U.S. government securities. Sentinel will choose the types of U.S. government securities that it believes will provide capital preservation and the best return with the least risk in light of its analysis of current market conditions and its outlook for interest rates and the economy.

The Fund invests substantially in U.S. government mortgage-backed securities issued and/or guaranteed by the Federal National Mortgage Association (“FNMA” or “Fannie Mae”), the Federal Home Loan Mortgage Corporation (“FHLMC” or “Freddie Mac”) and the Government National Mortgage Association (“GNMA” or “Ginnie Mae”).

The Fund may attempt to hedge various risks, such as interest rate risk, using derivative instruments (e.g., futures and options on futures, swaps, options on swaps, and caps and floors), and may use derivative instruments for other investment purposes such as replicating permitted investments, as long as such investments do not have the effect of leveraging portfolio risks. The Fund is not required to use hedging and may choose not to do so.

The Fund may sell a security if the security is overvalued on a relative basis compared to other securities available in the market or for duration management purposes. The Fund may also sell a security to meet redemptions.

The Fund utilizes an active trading approach, which may result in portfolio turnover greater than 100%.

Risk [Heading]

rr_RiskHeading

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

You could lose money by investing in the Fund. The following is a summary description of the principal risks of investing in the Fund:

· Derivatives Risk. Derivative investments involve counterparty risk (the risk that the counterparty of the derivative transaction will be unable to honor its financial obligation to the Fund), basis risk (the risk that the derivative instrument will not fully offset the underlying positions), and liquidity risk (the risk that the Fund cannot sell the derivative instrument because of an illiquid secondary market). In addition, the portfolio manager may incorrectly forecast the values of securities, currencies or interest rates or other economic factors in using derivatives for the Fund.

· General Fixed-Income Securities Risk. The market prices of bonds, including those issued by the U.S. government, go up as interest rates fall, and go down as interest rates rise. As a result, the net asset value of the shares of Funds holding bonds will fluctuate with conditions in the bond markets.

· Government Securities Risk. Economic, business, or political developments may affect the ability of government-sponsored guarantors to repay principal and to make interest payments on the securities in which the Fund invests. In addition, certain of these securities, including those issued or guaranteed by FNMA and FHLMC, are not backed by the full faith and credit of the U.S. government.

·  Mortgage-Backed Securities Risk. Mortgage-backed securities represent interests in “pools” of mortgages and are subject to certain additional risks. When interest rates rise, certain obligations will be paid off by the obligor more slowly than anticipated causing the value of these securities to fall. This is known as extension risk. In addition, adjustable and fixed rate mortgage-related securities are subject to prepayment risk. When interest rates decline, borrowers may pay off their mortgages sooner than expected. This can reduce the returns of the Fund because the Fund may have to reinvest that money at the lower prevailing interest rates. These securities also are subject to risk of default on the underlying mortgage, particularly during periods of economic downturn.

· Portfolio Turnover Risk. An active trading approach increases the Fund’s costs and may reduce the Fund’s performance. It may also increase the amount of capital gains tax that you have to pay on the Fund’s returns.

Bar Chart and Performance Table [Heading]

Performance

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

The following bar chart and table provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for 1, 5 and 10 years compare with those of broad measures of market performance. The bar chart shows changes in the Fund’s performance for Class A shares for each calendar year over a ten-year period. Sales charges are not reflected in the bar chart. If sales charges were reflected, returns would be less than those shown. However, the table includes, for share classes with a sales charge, the effect of the maximum sales charge, including any contingent deferred sales charge that would apply to a redemption at the end of the period. How the Fund performed in the past is not necessarily an indication of how the Fund will perform in the future. Updated information on the Fund’s results can be obtained by visiting www.sentinelinvestments.com.

Class A returns shown are based on the 2.25% maximum sales charge and are not adjusted to reflect a maximum 4% sales charge in effect from inception through April 10, 2005 and from June 1, 2006 through July 31, 2010, nor have they been adjusted to reflect the maximum sales charge of 2% in effect from April 11, 2005 to May 31, 2006. If they were, the returns would be lower. The Class C share returns prior to June 1, 2006 (the inception date for the Class C shares) are based on the returns of the Class A shares adjusted to reflect that Class C shares do not charge a front-end sales charge and adjusted for Class C’s estimated higher expenses. Class I share performance prior to May 4, 2007 (the inception date for the Class I shares) is based on the Fund’s Class A share performance, restated to reflect that Class I shares are offered without a sales charge.

Effective March 30, 2013, the Fund replaced its primary benchmark index (Barclays US Government Bond Index) and secondary benchmark index (Barclays US Mortgage Backed Securities Index) with one index, the Barclays US Government/Mortgage Backed Securities Index, because the Fund believes this one index, which consists of the asset classes in which the Fund invests, is a more appropriate measure of the Fund's investment strategy.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund normally divides its assets among several broad asset classes. Sentinel has broad discretion in allocating assets among the classes. The classes are:

1. INVESTMENT-GRADE BONDS. The Fund may invest up to 70% of its total assets in U.S. and non-U.S. sovereign government debt, and U.S. and non- U.S. dollar denominated investment-grade corporate bonds, and may include dollar roll transactions.

2. BELOW INVESTMENT-GRADE BONDS. The Fund may invest up to 70% of its total assets in U.S. dollar and non-U.S. dollar -denominated bonds rated below investment-grade (e.g., rated below BBB by Standard and Poor’s or below Baa by Moody’s) or which are unrated. These bonds are sometimes called “junk bonds”. The Fund expects that normally, no more than 45% of its total assets will be invested in this asset class, but Sentinel may increase the total assets invested in this asset class up to 70% for short periods of time when Sentinel believes that this asset class offers attractive yields and good value relative to other asset classes.

3. EQUITY AND EQUITY-RELATED SECURITIES. The Fund may invest up to 100% of its total assets in these securities, including common stocks, preferred stocks, and debt securities that are convertible into equity securities. In choosing investments within this category, investments which offer relatively high dividend or interest yields will be emphasized, but there will also be some emphasis on the potential for capital appreciation. The Fund may invest up to 70% of its total assets in foreign securities, including emerging markets.

The Fund may attempt to hedge various risks, such as interest rate and currency risk, using derivative instruments (e.g., exchange-traded futures and options, and other derivatives such as swaps, options on swaps, and caps and floors), and may use derivative instruments for other investment purposes such as replicating permitted investments, as long as such investments do not have the effect of leveraging portfolio risks. The Fund is not required to use hedging and may choose not to do so.

When making allocation decisions for the portfolio, the investment team works collaboratively to determine the appropriate allocation weightings based on their consideration of top-down macro-economic data relating to the U.S. and global markets, as well as bottom-up fundamental analysis to determine which asset classes appear to offer better relative value.

The Fund utilizes an active trading approach, which may result in portfolio turnover greater than 100%.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

You could lose money by investing in the Fund. The following is a summary description of the principal risks of investing in the Fund:

· Asset Allocation Risk The Fund’s allocations to the various asset classes and market sectors could cause the Fund to underperform other funds with a similar investment objective.

· Derivatives Risk. Derivative investments involve counterparty risk (the risk that the counterparty of the derivative transaction will be unable to honor its financial obligation to the Fund), basis risk (the risk that the derivative instrument will not fully offset the underlying positions), and liquidity risk (the risk that the Fund cannot sell the derivative instrument because of an illiquid secondary market). In addition, the portfolio manager may incorrectly forecast the values of securities, currencies or interest rates or other economic factors in using derivatives for the Fund.

· Emerging Markets Risk. The risks of foreign investments are usually much greater for the emerging markets. Investments in emerging markets may be considered speculative. Emerging markets are riskier because they develop unevenly and may never fully develop. In addition, many emerging securities markets have lower trading volumes and less liquidity than developed markets.

· Foreign Banks and Securities Depositories Risk. Some foreign banks and securities depositories in which the Fund generally holds its foreign securities may be recently organized or new to the foreign custody business. In addition, there may be limited or no regulatory oversight over their operations. Also, the laws of certain countries may put limits on the Fund’s ability to recover its assets if a foreign bank, depository or issuer of a security, or any of their agents, goes bankrupt.

· General Fixed-Income Securities Risk. The market prices of bonds, including those issued by the U.S. government, go up as interest rates fall, and go down as interest rates rise. As a result, the net asset value of the Fund will fluctuate with conditions in the bond markets. In the case of corporate bonds and commercial paper, values may fluctuate as perceptions of credit quality change. In addition, corporate bonds may be downgraded or default. During periods of declining interest rates or for other reasons, bonds may be “called”, or redeemed, by the bond issuer prior to the bond’s maturity date, resulting in the Fund receiving payment earlier than expected. This may reduce the Fund’s income if the proceeds are reinvested at a lower interest rate.

· General Foreign Securities Risk. Investments in foreign securities may be affected unfavorably by changes in currency rates or exchange control regulations, or political or social instability in the particular foreign country or region. The Fund is not required to hedge against changes in foreign currency exchange rates.

· Government Securities Risk. Economic, business, or political developments may affect the ability of government-sponsored guarantors to repay principal and to make interest payments on the securities in which the Fund invests. In addition, certain of these securities, including those issued or guaranteed by FNMA and FHLMC, are not backed by the full faith and credit of the U.S. government.

· Investment Style Risk. The Fund invests in “growth” and “value” stocks, and in stocks with characteristics of both. These different types of stocks may be out of favor at any particular time. The stocks of “growth” companies may be more sensitive to investor perceptions about company earnings and may be more volatile than the market in general. The stocks of “value” companies may be undervalued by the market for long periods of time.

· Lower-Quality Bonds Risk. Bonds with lower credit ratings are more speculative and likely to default than higher-quality bonds. Lower-rated bonds also tend to fluctuate more widely in value.

· Mortgage-Backed Securities Risk. Mortgage-backed securities represent interests in “pools” of mortgages and are subject to certain additional risks. When interest rates rise, certain obligations will be paid off by the obligor more slowly than anticipated causing the value of these securities to fall. This is known as extension risk. In addition, adjustable and fixed rate mortgage-related securities are subject to prepayment risk. When interest rates decline, borrowers may pay off their mortgages sooner than expected. This can reduce the returns of the Fund because the Fund may have to reinvest that money at the lower prevailing interest rates. These securities also are subject to risk of default on the underlying mortgage, particularly during periods of economic downturn.

· Portfolio Turnover Risk. An active trading approach increases the Fund’s costs and may reduce the Fund’s performance. It may also increase the amount of capital gains tax that you have to pay on the Fund’s returns.

· Sector Risk. Investments in a particular sector may trail returns from other economic sectors.

· Stock Market and Selection Risk. The stock market may go down in value, and may go down sharply and unpredictably. The stocks selected by the portfolio manager may underperform the stock market or other funds with similar investment objectives and investment strategies.

The following bar chart and table provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for 1 and 5 years and since inception compare with those of broad measures of market performance. The bar chart shows changes in the Fund’s performance for Class A shares for each calendar year since inception. Sales charges are not reflected in the bar chart. If sales charges were reflected, returns would be less than those shown. However, the table includes, for share classes with a sales charge, the effect of the maximum sales charge, including any contingent deferred sales charge that would apply to a redemption at the end of the period. How the Fund performed in the past is not necessarily an indication of how the Fund will perform in the future. Updated information on the Fund’s results can be obtained by visiting www.sentinelinvestments.com.

Performance of the Class A shares prior to June 30, 2012, has not been adjusted to reflect the decrease in the maximum 12b-1 fee from 0.30% to 0.25%. If it had, those returns would be higher. Performance of the Class I shares prior to December 17, 2010 (the inception date for the Class I shares) is based on the Fund’s Class A share performance, restated to reflect that Class I shares are offered without a sales charge. Effective December 17, 2010, the Fund changed its investment strategies.

SENTINEL MID CAP II FUND | SENTINEL MID CAP II FUND

SENTINEL MID CAP II FUND

Investment Objective

The Fund seeks long-term capital appreciation.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $25,000 in shares of the Sentinel Funds that include Class A shares. More information about these and other discounts is available from your financial professional and in the section entitled “Share Classes” on page 98 of the Fund’s prospectus and “How to Purchase Shares and Reduce Sales Charges” on page 52 of the Fund’s statement of additional information.

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same.

Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Expense Example SENTINEL MID CAP II FUND (USD $)	1 Year	3 Years	5 Years	10 Years
CLASS A	642	942	1,263	2,170
CLASS C	331	712	1,220	2,615
CLASS I	105	328	569	1,259

You would pay the following expenses if you did not redeem your shares:

Expense Example No Redemption (USD $)	1 Year	3 Years	5 Years	10 Years
SENTINEL MID CAP II FUND CLASS C	231	712	1,220	2,615

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 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 158% of the average value of its portfolio.

Principal Investment Strategies

The Fund normally invests at least 80% of its net assets in mid-capitalization companies. For this purpose, mid-capitalization companies are companies that have, at the time of purchase, market capitalizations between $500 million and $25 billion. The Fund seeks to invest primarily in common stocks of mid-capitalization companies that Sentinel believes are high quality, have superior business models, solid management teams, sustainable growth potential and are attractively valued. The Fund may invest without limitation in foreign securities, although only where the securities are trading in the U.S. or Canada and only where trading is denominated in U.S. or Canadian dollars.

Up to 25% of the Fund’s assets may be invested in securities within a single industry. For portfolio construction purposes, the Fund uses the Standard & Poor’s MidCap 400 Index as a sector-weighting guide, generally using a plus or minus 25% weighting. The Fund attempts to be well-balanced across major economic sectors. Although the Fund may invest in any economic sector, at times it may emphasize one or more particular sectors.

The Fund would typically sell a security if the portfolio managers believe it is overvalued, if the original investment premise is no longer true, if the market cap exceeds a specified threshold and/or if the holding size exceeds the portfolio managers’ company or sector weighting guidelines. The Fund may also sell a partial position in a security in order to manage the size of the position. A security may also be sold to meet redemptions.

Principal Investment Risks

You could lose money by investing in the Fund. The following is a summary description of the principal risks of investing in the Fund:

· General Foreign Securities Risk. Investments in foreign securities may be affected unfavorably by changes in currency rates or exchange control regulations, or political and/or social instability in a particular foreign country or region.

· Investment Style Risk. The Fund’s growth style of investing may be out of favor at any particular time. The stocks of growth companies may be more sensitive to investor perceptions about company earnings than other stocks and may be more volatile than the market in general.

· Restricted and Illiquid Securities Risk. The Fund will not be able to readily resell illiquid securities and resale of some of these securities may be restricted by law or contractual provisions. The inability to sell these securities at the most opportune time may negatively affect the Fund’s net asset value.

· Sector Risk. Investments in a particular sector may trail returns from other economic sectors.

· Stocks of Smaller Companies Risk. The stocks of small- and/or mid-capitalization companies in which the Fund invests typically involve more risk than the stocks of larger companies. These smaller companies may have more limited financial resources and product lines, and may have less seasoned managers. In addition, these stocks may trade less frequently and in lower share volumes, making them subject to wider price fluctuations.

Performance

The following bar chart and table provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for 1, 5 and 10 years compare with those of broad measures of market performance. The bar chart shows changes in the Fund’s performance for Class I shares for each calendar year over a ten-year period. The table includes, for share classes with a sales charge, the effect of the maximum sales charge, including any contingent deferred sales charge that would apply to a redemption at the end of the period. How the Fund performed in the past (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated information on the Fund’s results can be obtained by visiting www.sentinelinvestments.com.

The Sentinel Mid Cap II Fund, which began operations on May 4, 2007, is a successor to the Synovus Mid Cap Value Fund, which was a successor to a similarly managed collective investment fund, which began operations on April 3, 2000. Performance for the Fund is based on the performance of its predecessors, which had different expenses but substantially similar investment risks. Performance from October 24, 2001 to May 4, 2007 is based on the Synovus Mid Cap Value Fund’s Class A, Class C or Institutional Class shares, as applicable, adjusted, in the case of Class A shares, for the current maximum sales charge. Performance of the Class A shares from their inception on May 4, 2007 to June 29, 2012, has not been adjusted to reflect the lower maximum 12b-1 fee in effect prior to May 4, 2007 or the decrease in the maximum 12b-1 fee, effective June 30, 2012, from 0.30% to 0.25%. If it had, those returns would be higher. Information for Class I shares is presented because the Class I share class has the longest period of annual returns.

Effective at the close of business on January 13, 2012, the Fund’s investment strategies were modified from a focus on value-style investing to a focus on investing in high quality companies with sustainable growth potential and attractive valuations, and the Fund changed its portfolio management team. The performance information provided below relates to the Fund’s investment strategies as implemented by the Fund’s sub-advisers prior to the close of business January 13, 2012.

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $25,000 in shares of the Sentinel Funds that include Class A shares. More information about these and other discounts is available from your financial professional and in the section entitled “Share Classes” on page 98 of the Fund’s prospectus and “How to Purchase Shares and Reduce Sales Charges” on page 52 of the Fund’s statement of additional information.

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same.

Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Expense Example Sentinel International Equity Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Class A	641	939	1,258	2,159
Class C	408	942	1,601	3,365
CLASS I	96	300	520	1,155

You would pay the following expenses if you did not redeem your shares:

Expense Example No Redemption (USD $)	1 Year	3 Years	5 Years	10 Years
Sentinel International Equity Fund Class C	308	942	1,601	3,365

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 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 37% of the average value of its portfolio.

Principal Investment Strategies

The Fund normally invests at least 80% of its net assets in equity securities. The Fund invests mainly in common stocks of established companies located in or that conduct their business mainly in one or more foreign countries, which may include emerging markets. The Fund will normally be invested in ten or more foreign countries and may invest up to 40% of its assets in any one country if Sentinel feels that economic and business conditions make it appropriate to do so. The Fund focuses its investments on developed foreign countries, but may invest up to 25% of its total assets in emerging markets. It normally will have substantial investments in European countries. Normally, at least 75% of the Fund’s total assets are invested in securities of non-U.S. issuers selected by Sentinel mainly for their long-term capital growth prospects. The remaining 25% may be invested in companies organized in the United States that have at least 50% of their assets and/or revenues outside the United States. The Fund also expects to purchase American Depositary Receipts (ADRs) and Global Depositary Receipts in bearer form, which are designed for use in non-U.S. securities markets.

The Fund also may invest in convertible or debt securities rated Baa or higher by Moody’s Investors Service, Inc. or BBB or higher by Standard & Poor’s.

Sentinel applies a multi-dimensional strategy for portfolio construction — trend identification, stock selection and risk management. Trends are identified that affect global and regional economic and financial environments, setting a framework for stock selection; stocks are then analyzed and ranked based on the following five factors: valuation, growth, management, business quality and balance sheet strength. Risk is managed through portfolio diversification. Typically, the Fund has no more than double the weight of the MSCI EAFE index or less than half the weight of the index in the largest countries in the index.

The Fund generally may sell a security when there is a deterioration of one or more of the five factors described above or when the portfolio manager identifies a more favorable investment opportunity. The Fund may also sell a security to meet redemptions.

Principal Investment Risks

You could lose money by investing in the Fund. The following is a summary description of the principal risks of investing in the Fund:

· Emerging Markets Risk. The risks of foreign investments are usually much greater for the emerging markets. Investments in emerging markets may be considered speculative. Emerging markets are riskier because they develop unevenly and may never fully develop. In addition, many emerging securities markets have lower trading volumes and less liquidity than developed markets.

· Foreign Banks and Securities Depositories Risk. Some foreign banks and securities depositories in which the Fund generally holds its foreign securities may be recently organized or new to the foreign custody business. In addition, there may be limited or no regulatory oversight over their operations. Also, the laws of certain countries may put limits on the Fund’s ability to recover its assets if a foreign bank, depository or issuer of a security, or any of their agents, goes bankrupt.

· General Foreign Securities Risk. Investments in foreign securities may be affected unfavorably by changes in currency rates or exchange control regulations, or political and/or social instability in a particular foreign country or region.

· Investment Style Risk. The Fund’s growth style of investing may be out of favor at any particular time. The stocks of growth companies may be more sensitive to investor perceptions about company earnings than other stocks and may be more volatile than the market in general.

· Sector Risk. Investments in a particular sector may trail returns from other economic sectors.

· Stock Market and Selection Risk. The stock market may go down in value, and may go down sharply and unpredictably. The stocks selected by the portfolio manager may underperform the stock market or other funds with similar investment objectives and investment strategies.

Performance

The following bar chart and table provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for 1, 5 and 10 years compare with those of a broad measure of market performance. The bar chart shows changes in the Fund’s performance for Class A shares for each calendar year over a ten-year period. Sales charges are not reflected in the bar chart. If sales charges were reflected, returns would be less than those shown. However, the table includes, for share classes with a sales charge, the effect of the maximum sales charge, including any contingent deferred sales charge that would apply to a redemption at the end of the period. How the Fund performed in the past (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated information on the Fund’s results can be obtained by visiting www.sentinelinvestments.com.

Performance of the Class A shares prior to June 30, 2012, has not been adjusted to reflect the decrease in the maximum 12b-1 fee from 0.30% to 0.25%. If it had, those returns would be higher. Performance of the Class I shares prior to August 27, 2007 (the inception date for the Class I shares) is based on the Fund’s Class A share performance, restated to reflect that Class I shares are offered without a sales charge.

Inception: 1993

Annual Total Return for Class A Shares (%) as of December 31

During the ten-year period shown in the above bar chart, the highest return for a quarter was 24.26% (quarter ended June 30, 2009) and the lowest return for a quarter was -21.09% (quarter ended September 30, 2011).

After-tax returns are calculated using the historical highest applicable individual federal marginal income tax rates in effect during the relevant period and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. After-tax returns are shown only for Class A shares and after-tax returns for other classes of shares will vary.

[1] You pay a deferred sales charge of 1% on certain redemptions of Class A shares made within twelve months of purchase if you bought them without an initial sales charge as part of an investment of $1,000,000 or more.

[1] 12b-1 fees have been restated to reflect a reduction in the maximum fee from 0.30% to 0.25% effective June 30, 2012. Because of this restatement, the Total Annual Fund Operating Expenses do not correlate to the ratio of expenses to average net assets shown in the Fund's most recent annual report.

[1] Return after taxes on distributions and sale of fund shares may be higher than return before taxes and/or return after taxes on distributions when a net capital loss occurs upon the redemption of fund shares.

Strategy [Heading]

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund normally invests at least 80% of its net assets in mid-capitalization companies. For this purpose, mid-capitalization companies are companies that have, at the time of purchase, market capitalizations between $500 million and $25 billion. The Fund seeks to invest primarily in common stocks of mid-capitalization companies that Sentinel believes are high quality, have superior business models, solid management teams, sustainable growth potential and are attractively valued. The Fund may invest without limitation in foreign securities, although only where the securities are trading in the U.S. or Canada and only where trading is denominated in U.S. or Canadian dollars.

Up to 25% of the Fund’s assets may be invested in securities within a single industry. For portfolio construction purposes, the Fund uses the Standard & Poor’s MidCap 400 Index as a sector-weighting guide, generally using a plus or minus 25% weighting. The Fund attempts to be well-balanced across major economic sectors. Although the Fund may invest in any economic sector, at times it may emphasize one or more particular sectors.

The Fund would typically sell a security if the portfolio managers believe it is overvalued, if the original investment premise is no longer true, if the market cap exceeds a specified threshold and/or if the holding size exceeds the portfolio managers’ company or sector weighting guidelines. The Fund may also sell a partial position in a security in order to manage the size of the position. A security may also be sold to meet redemptions. A security will be sold when it is determined that it no longer meets the environmental, social and/or corporate governance performance criteria.

Sustainable and Responsible Investing. The Fund employs a process of environmental, social and corporate governance (“ESG”) screening that is overseen by Sentinel’s in-house sustainable research department. While no investment is ever made solely based on the qualitative criteria alone, the Fund believes sustainable screening provides a unique and more comprehensive view of the companies it considers for investment. Generally, companies are eliminated from investment consideration if they produce tobacco or tobacco products or alcoholic beverages; generate nuclear power or supply nuclear facilities with industry specific components, as a primary line of business; have material interests in the manufacture of weapons or weapons-specific components; are involved in gambling as a main line of business; and/or lack diversity at the level of the board of directors/senior management. The Fund favors companies that publish and enforce codes of conduct and vendor standards; promote equal opportunity, diversity and good employee relations; are sensitive to community concerns; seek alternatives to animal testing when not required by law; and/or have minimal impact on the environment and engage in proactive environmental initiatives.

Sentinel may, in its discretion, choose to apply additional screens, modify the application of the screens listed above or vary the application of the screens listed above to the Funds’ investments at any time without shareholder approval.

For additional information on the environmental, social and governance screening process used by the Fund, please see “Additional Information About Each Fund — Investment Objectives and Strategies — Sentinel Sustainable Mid Cap Opportunities Fund — Principal Investment Strategies” at page 88 of the Prospectus.

·  Stocks of Smaller Companies Risk. The stocks of small- and mid-capitalization companies in which the Fund invests typically involve more risk than the stocks of larger companies. These smaller companies may have more limited financial resources, narrower product lines, and may have less seasoned managers. In addition, these stocks may trade less frequently and in lower share volumes, making them subject to wider price fluctuations.

· Sustainable/Responsible Investing Risk. The Fund’s environmental, social and corporate governance criteria may cause the Fund to forgo opportunities to buy certain securities, and/or forgo opportunities to gain exposure to certain industries, sectors, regions and countries. In addition, the Fund may be required to sell a security when it might otherwise be disadvantageous for it to do so.

The Sentinel Sustainable Mid Cap Opportunities Fund, which began operations on April 4, 2008, is a successor to the Citizens Emerging Growth Fund, which began operations on February 8, 1994. Performance for the Class A shares of the Fund prior to April 4, 2008 is based on the performance of the Standard shares of the Citizens Emerging Growth Fund, which was offered without a sales charge, and has been restated to reflect the current maximum sales charge. Performance of the Class A shares from their inception on April 4, 2008 to June 29, 2012, has not been adjusted to reflect the lower maximum 12b-1 fee in effect prior to April 4, 2008 or the decrease in the maximum 12b-1 fee, effective June 30, 2012, from 0.30% to 0.25%. If it had, those returns would be higher. Performance for the Class I shares from November 1, 1999 to April 4, 2008 is based on the performance of the Institutional shares of Citizens Emerging Growth Fund, which had different expenses but substantially similar investment risks.

[1] The Standard & Poor's MidCap 400 Index measures the performance of the mid-sized company segment of the U.S. stock market. The market value-weighted index is based on 400 stocks chosen on the basis of market capitalization, liquidity and industry group representation. The Fund compares its performance to this index because Fund management believes it is an appropriate alternative measure of the Fund's investment strategy.

Sentinel Short Maturity Government Fund

Investment Objective

The Fund seeks high current income and limited fluctuations in principal value.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $1,000,000 in shares of the Sentinel Funds that include Class A shares. More information about these and other discounts is available from your financial professional and in the section entitled “Share Classes” on page 98 of the Fund’s prospectus and “How to Purchase Shares and Reduce Sales Charges” on page 52 of the Fund’s statement of additional information.

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same.

Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Expense Example Sentinel Short Maturity Government Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Class A	187	372	572	1,150
Class S	127	397	686	1,511

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 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 27% of the average value of its portfolio.

Principal Investment Strategies

The Fund normally invests at least 80% of its net assets in U.S. government securities with average lives, at the time of purchase, of three years or less, and related derivatives. Related derivatives include exchange-traded futures on U.S. Treasury notes and bonds, and options on these futures, and other derivatives intended to hedge interest rate risk, such as swaps, options on swaps, and interest rate caps and floors. The remainder of the Fund’s assets may be invested in U.S. government securities with other maturities. Normally, the dollar-weighted average life of the Fund’s portfolio is less than three years. The U.S. government securities in which the Fund invests include direct obligations of the U.S. Treasury, obligations guaranteed by the U.S. government and obligations of U.S. government agencies and instrumentalities. The Fund is not required to invest set amounts in any type of U.S. government securities. Sentinel chooses the types of U.S. government securities that it believes will provide capital preservation and the best return with the least risk in light of its analysis of current market conditions and its outlook for interest rates and the economy.

The Fund invests substantially in U.S. government mortgage-backed securities issued and/or guaranteed by the Federal National Mortgage Association (“FNMA” or “Fannie Mae”), the Federal Home Loan Mortgage Corporation (“FHLMC” or “Freddie Mac”) and the Government National Mortgage Association (“GNMA” or “Ginnie Mae”). The Fund seeks to invest in mortgage-backed securities with shorter average lives by focusing on securities that have been outstanding for a long period, or which have limited original terms.

The Fund may attempt to hedge various risks such as interest rate risk using derivative instruments (e.g., futures and options on futures, swaps, options on swaps, and caps and floors), and may use derivative instruments for other investment purposes such as replicating permitted investments, as long as such investments do not have the effect of leveraging portfolio risks. The Fund is not required to use hedging and may choose not to do so.

The Fund may sell a security if the security is overvalued on a relative basis compared to other securities available in the market or for duration management purposes. The Fund may also sell a security to meet redemptions.

Principal Investment Risks

You could lose money by investing in the Fund. The following is a summary description of the principal risks of investing in the Fund:

· Derivatives Risk. Derivative investments involve counterparty risk (the risk that the counterparty of the derivative transaction will be unable to honor its financial obligation to the Fund), basis risk (the risk that the derivative instrument will not fully offset the underlying positions), and liquidity risk (the risk that the Fund cannot sell the derivative instrument because of an illiquid secondary market). In addition, the portfolio manager may incorrectly forecast the values of securities, currencies or interest rates or other economic factors in using derivatives for the Fund.

· General Fixed-Income Securities Risk. The market prices of bonds, including those issued by the U.S. government, go up as interest rates fall, and go down as interest rates rise. As a result, the net asset value of the shares of Funds holding bonds will fluctuate with conditions in the bond markets.

· Government Securities Risk. Economic, business, or political developments may affect the ability of government-sponsored guarantors to repay principal and to make interest payments on the securities in which the Fund invests. In addition, certain of these securities, including those issued or guaranteed by FNMA and FHLMC, are not backed by the full faith and credit of the U.S. government.

·  Mortgage-Backed Securities Risk. Mortgage-backed securities represent interests in “pools” of mortgages and are subject to certain additional risks. When interest rates rise, certain obligations will be paid off by the obligor more slowly than anticipated causing the value of these securities to fall. This is known as extension risk. In addition, adjustable and fixed rate mortgage-related securities are subject to prepayment risk. When interest rates decline, borrowers may pay off their mortgages sooner than expected. This can reduce the returns of the Fund because the Fund may have to reinvest that money at the lower prevailing interest rates. These securities also are subject to risk of default on the underlying mortgage, particularly during periods of economic downturn.

Performance

The following bar chart and table provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for 1, 5 and 10 years compare with those of broad measures of market performance. The bar chart shows changes in the Fund’s performance for Class A shares for each calendar year over a ten-year period. Sales charges are not reflected in the bar chart. If sales charges were reflected, returns would be less than those shown. However, the table includes, for share classes with a sales charge, the effect of the maximum sales charge. How the Fund performed in the past (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated information on the Fund’s results can be obtained by visiting www.sentinelinvestments.com.

Class A returns prior to June 1, 2006, have not been adjusted to reflect the decrease in the maximum 12b-1 fee from 0.35% to 0.25%. If they had, those returns would be higher. The Class A returns shown are based on the 1% maximum sales charge and are not adjusted to reflect a maximum sales charge of 3% in effect from June 1, 2006 to December 31, 2008. If they were, the returns would be lower. The Class S share returns prior to March 4, 2005 (the inception date for the Class S shares) are based on the returns of the Class A shares adjusted to reflect that Class S shares do not charge a front-end sales charge and adjusted for Class S’s higher expenses.

Annual Total Return for Class A Shares (%) as of December 31

During the ten-year period shown in the above bar chart, the highest return for a quarter was 2.11% (quarter ended September 30, 2006) and the lowest return for a quarter was -0.47% (quarter ended March 31, 2005).

After-tax returns are calculated using the historical highest applicable individual federal marginal income tax rates in effect during the relevant period and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. After-tax returns are shown only for Class A shares and after-tax returns for other classes of shares will vary.

[1] You pay a deferred sales charge of 0.50% on certain redemptions of Class A shares made within twelve months of purchase if you bought them without an initial sales charge as part of an investment of $1,000,000 or more.

[1] Sentinel Financial Services Company, the Fund's distributor, has contractually agreed, effective April 1, 2013, to waive 0.25% of Rule 12b-1 fees for Class S shares. This waiver agreement will remain in effect through March 31, 2014, unless renewed by the Fund's distributor. Excluding this waiver would result in Rule 12b-1 fees of 0.75%.

[1] Return after taxes on distributions and sale of fund shares may be higher than return before taxes and/or return after taxes on distributions when a net capital loss occurs upon the redemption of fund shares.

[2] The Barclays US Mortgage Backed Securities Index is an index of agency mortgage-backed pass-through securities issued by Government National Mortgage Association (GNMA), Federal National Mortgage Association (FNMA), and Federal Home Loan Mortgage Corporation (FHLMC). The Fund compares its performance to this index because the Fund's investment strategy includes investments in the asset classes that comprise this index.

[1] The Barclays US Mortgage Backed Securities Index is an index of agency mortgage-backed pass-through securities issued by Government National Mortgage Association (GNMA), Federal National Mortgage Association (FNMA), and Federal Home Loan Mortgage Corporation (FHLMC). The Fund compares its performance to this index because the Fund's investment strategy includes investments in the asset classes that comprise this index.

[2] You pay a deferred sales charge of 0.50% on certain redemptions of Class A shares made within twelve months of purchase if you bought them without an initial sales charge as part of an investment of $1,000,000 or more.

[3] Sentinel Financial Services Company, the Fund's distributor, has contractually agreed, effective April 1, 2013, to waive 0.25% of Rule 12b-1 fees for Class S shares. This waiver agreement will remain in effect through March 31, 2014, unless renewed by the Fund's distributor. Excluding this waiver would result in Rule 12b-1 fees of 0.75%.

[4] Return after taxes on distributions and sale of fund shares may be higher than return before taxes and/or return after taxes on distributions when a net capital loss occurs upon the redemption of fund shares.

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 8% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund normally invests at least 80% of its net assets in common stocks. The Fund invests mainly in a diverse group of common stocks of well-established companies, typically above $5 billion in market capitalization, many of which historically have paid regular dividends. When appropriate, the Fund also may invest in preferred stocks or debentures convertible into common stocks. Up to 25% of the Fund’s assets may be invested in securities within a single industry. The Fund may invest without limitation in foreign securities. Under normal circumstances, the Fund invests predominantly in common stocks of U.S. companies.

Sentinel’s investment philosophy centers on building a diverse portfolio consisting largely of securities of high quality companies with a positive multi-year outlook offered at attractive valuation levels, based on a number of metrics, including value relative to its history, peers and/or the market over time. Although the Fund may invest in any economic sector, at times it may emphasize one or more particular sectors. Sentinel has a preference for companies that earn above-average rates of return on capital and that generate free cash flow. Additionally, earnings revision trends are important.

The Fund may sell a stock if the fundamentals of the company are deteriorating or the original investment premise is no longer valid, the stock is trading meaningfully higher than what the portfolio manager believes is a fair valuation, to manage the size of the holding or the sector weighting and/or to take advantage of a more attractive investment opportunity. A stock may also be sold to meet redemptions.

Risk [Heading]

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

You could lose money by investing in the Fund. The following is a summary description of the principal risks of investing in the Fund:

· Foreign Banks and Securities Depositories Risk. Some foreign banks and securities depositories in which the Fund generally holds its foreign securities may be recently organized or new to the foreign custody business. In addition, there may be limited or no regulatory oversight over their operations. Also, the laws of certain countries may put limits on the Fund’s ability to recover its assets if a foreign bank, depository or issuer of a security, or any of their agents, goes bankrupt.

· General Foreign Securities Risk. Investments in foreign securities may be affected unfavorably by changes in currency rates or exchange control regulations, or political and/or social instability in a particular foreign country or region.

· Investment Style Risk. The Fund uses a “blend” strategy to invest in both growth and value stocks, and/or in stocks with characteristics of both. This strategy may be out of favor at any particular time. The prices of growth stocks may fall dramatically if the company fails to meet earnings or revenue projections. The prices of value stocks may lag the stock market for long periods of time if the market fails to recognize the company’s intrinsic worth.

· Sector Risk. Investments in a particular sector may trail returns from other economic sectors.

· Stock Market and Selection Risk. The stock market may go down in value, and may go down sharply and unpredictably. The stocks selected by the portfolio manager may underperform the stock market or other funds with similar investment objectives and investment strategies.

The following bar chart and table provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for 1, 5 and 10 years compare with those of broad measures of market performance. The bar chart shows changes in the Fund’s performance for Class A shares for each calendar year over a ten-year period. Sales charges are not reflected in the bar chart. If sales charges were reflected, returns would be less than those shown. However, the table includes, for share classes with a sales charge, the effect of the maximum sales charge, including any contingent deferred sales charge that would apply to a redemption at the end of the period. How the Fund performed in the past (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated information on the Fund’s results can be obtained by visiting www.sentinelinvestments.com.

Performance of the Class A shares prior to June 30, 2012, has not been adjusted to reflect the decrease in the maximum 12b-1 fee from 0.30% to 0.25%. If it had, those returns would be higher. Performance of the Class I shares prior to May 4, 2007 (the inception date for the Class I shares) is based on the Fund’s Class A share performance, restated to reflect that Class I shares are offered without a sales charge.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund normally invests primarily in common stocks and investment-grade bonds with at least 25% of its assets in bonds and at least 25% of its assets in common stock. When determining this percentage, convertible bonds and/or preferred stocks are considered common stocks, unless these securities are held primarily for income. Sentinel will divide the Fund’s assets among stocks and bonds based on whether it believes stocks or bonds offer a better value at the time. More bonds normally enhance price stability, and more stocks usually enhance growth potential. Up to 25% of the Fund’s assets may be invested in securities within a single industry.

With respect to equities, Sentinel’s investment philosophy centers on building a diverse portfolio consisting largely of securities of high quality companies with a positive multi year outlook offered at attractive valuation levels, based on a number of metrics, including value relative to its history, peers and/or the market over time. Although the Fund may invest in any economic sector, at times it may emphasize one or more particular sectors. Sentinel has a preference for companies that earn above-average rates of return on capital and that generate free cash flow. Additionally, earnings revision trends are important. The Fund may invest without limitation in foreign securities. Under normal circumstances, the equity securities in which the Fund invests are predominantly those of U.S companies.

The bond portion of the Fund may be invested without limitation in bonds in the first through the fourth highest rating categories of Moody’s (Aaa to Baa) and Standard and Poor’s (AAA to BBB). No more than 20% of the Fund’s total assets may be invested in lower-quality bonds (e.g., bonds rated below Baa by Moody’s or BBB by Standard & Poor’s). These lower-quality bonds have speculative characteristics. The Fund will only purchase securities rated B3 or lower by Moody’s or lower than B- by Standard and Poor’s if Sentinel believes the quality of the bonds is higher than indicated by the rating. The Fund may also purchase unrated bonds.

The Fund may make unlimited investments in U.S. government mortgage-backed securities issued and/or guaranteed by the Federal National Mortgage Association (“FNMA” or “Fannie Mae”), the Federal Home Loan Mortgage Corporation (“FHLMC” or “Freddie Mac”) and by the Government National Mortgage Association (“GNMA” or “Ginnie Mae”). While the original maximum life of a mortgage-backed security considered for this Fund can vary, its average life is likely to be substantially less than the original maturity of the underlying mortgages, because the mortgages in these pools may be prepaid, refinanced, curtailed, or foreclosed. Prepayments are passed through to the mortgage-backed security holder along with regularly scheduled minimum repayments of principal and payments of interest.

The Fund may attempt to hedge various risks, such as interest rate risk, using derivative instruments (e.g., exchange-traded futures and options, and other derivatives such as swaps, options on swaps, and caps and floors), and may use derivative instruments for other investment purposes such as replicating permitted investments, as long as such investments do not have the effect of leveraging portfolio risks. The Fund is not required to use hedging and may choose not to do so.

In managing the fixed-income portion of the portfolio, the Fund utilizes an active trading approach, which may result in portfolio turnover greater than 100%.

The Fund may sell a security if the fundamentals of the company are deteriorating or the original investment premise is no longer valid, the security is trading meaningfully higher than what the portfolio manager believes is a fair valuation, to manage the size of the holding or the sector weighting and/or to take advantage of a more attractive investment opportunity. The Fund may also sell a security to meet redemptions.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

You could lose money by investing in the Fund. The following is a summary description of the principal risks of investing in the Fund:

· Asset Allocation Risk The Fund’s allocations to the various asset classes and market sectors could cause the Fund to underperform other funds with a similar investment objective.

· Derivatives Risk. Derivative investments involve counterparty risk (the risk that the counterparty of the derivative transaction will be unable to honor its financial obligation to the Fund), basis risk (the risk that the derivative instrument will not fully offset the underlying positions), and liquidity risk (the risk that the Fund cannot sell the derivative instrument because of an illiquid secondary market). In addition, the portfolio manager may incorrectly forecast the values of securities, currencies or interest rates or other economic factors in using derivatives for the Fund.

· Foreign Banks and Securities Depositories Risk. Some foreign banks and securities depositories in which the Fund generally holds its foreign securities may be recently organized or new to the foreign custody business. In addition, there may be limited or no regulatory oversight over their operations. Also, the laws of certain countries may put limits on the Fund’s ability to recover its assets if a foreign bank, depository or issuer of a security, or any of their agents, goes bankrupt.

· General Fixed-Income Securities Risk. The market prices of bonds, including those issued by the U.S. government, go up as interest rates fall, and go down as interest rates rise. As a result, the net asset value of the Fund will fluctuate with conditions in the bond markets. In the case of corporate bonds and commercial paper, values may fluctuate as perceptions of credit quality change. In addition, corporate bonds may be downgraded or default. During periods of declining interest rates or for other reasons, bonds may be “called”, or redeemed, by the bond issuer prior to the bond’s maturity date, resulting in the Fund receiving payment earlier than expected. This may reduce the Fund’s income if the proceeds are reinvested at a lower interest rate.

· General Foreign Securities Risk. Investments in foreign securities may be affected unfavorably by changes in currency rates or exchange control regulations, or political and/or social instability in a particular foreign country or region.

· Government Securities Risk. Economic, business, or political developments may affect the ability of government-sponsored guarantors to repay principal and to make interest payments on the securities in which the Fund invests. In addition, certain of these securities, including those issued or guaranteed by FNMA and FHLMC, are not backed by the full faith and credit of the U.S. government.

· Investment Style Risk. The Fund uses a “blend” strategy to invest in both growth and value stocks, and/or in stocks with characteristics of both. This strategy may be out of favor at any particular time. The prices of growth stocks may fall dramatically if the company fails to meet earnings or revenue projections. The prices of value stocks may lag the stock market for long periods of time if the market fails to recognize the company’s intrinsic worth.

· Lower-Quality Bonds Risk. Bonds with lower credit ratings are more speculative and likely to default than higher-quality bonds. Lower-rated bonds also tend to fluctuate more widely in value.

· Mortgage-Backed Securities Risk. Mortgage-backed securities represent interests in “pools” of mortgages and are subject to certain additional risks. When interest rates rise, certain obligations will be paid off by the obligor more slowly than anticipated causing the value of these securities to fall. This is known as extension risk. In addition, adjustable and fixed rate mortgage-related securities are subject to prepayment risk. When interest rates decline, borrowers may pay off their mortgages sooner than expected. This can reduce the returns of the Fund because the Fund may have to reinvest that money at the lower prevailing interest rates. These securities also are subject to risk of default on the underlying mortgage, particularly during periods of economic downturn.

· Portfolio Turnover Risk. An active trading approach increases the Fund’s costs and may reduce the Fund’s performance. It may also increase the amount of capital gains tax that you have to pay on the Fund’s returns.

· Sector Risk. Investments in a particular sector may trail returns from other economic sectors.

· Stock Market and Selection Risk. The stock market may go down in value, and may go down sharply and unpredictably. The stocks selected by the portfolio manager may underperform the stock market or other funds with similar investment objectives and investment strategies.

The following bar chart and table provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for 1, 5 and 10 years compare with those of broad measures of market performance. The bar chart shows changes in the Fund’s performance for Class A shares for each calendar year over a ten-year period. Sales charges are not reflected in the bar chart. If sales charges were reflected, returns would be less than those shown. However, the table includes, for share classes with a sales charge, the effect of the maximum sales charge, including any contingent deferred sales charge that would apply to a redemption at the end of the period. How the Fund performed in the past (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated information on the Fund’s results can be obtained by visiting www.sentinelinvestments.com.

Performance of the Class A shares prior to June 30, 2012, has not been adjusted to reflect the decrease in the maximum 12b-1 fee from 0.30% to 0.25%. If it had, those returns would be higher. Performance of the Class I shares prior to August 27, 2007 (the inception date for the Class I shares) is based on the Fund’s Class A share performance, restated to reflect that Class I shares are offered without a sales charge.

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a non-diversified fund that invests in stocks of companies that Sentinel believes have attractive business models, solid management and growth potential.

As a non-diversified fund with fewer securities than a diversified portfolio, there is greater risk in that each holding has a greater impact on performance, either positively or negatively.

Sentinel looks to invest in high quality companies that are expected to grow as a result of superior investments, strong capital stewardship and unique positioning in attractive business segments. When selecting investments, focus is on company-specific variables, such as competitive industry dynamics, market leadership, proprietary products and services, and management expertise, as well as on financial characteristics, such as returns on sales and equity, debt/equity ratios and earnings and cash flow growth. In addition, Sentinel looks for companies that it perceives to be attractively valued relative to their future growth prospects, as well as to that of the market as a whole.

The Fund typically invests in 30-40 common stocks from any economic sector, and at times, it may emphasize one or more particular sectors. The Fund may invest up to 25% of its net assets in a single industry. While the Fund typically focuses on securities of U.S. companies, it may without limitation, invest in securities of foreign issuers.

Sentinel expects to sell Fund holdings when the fundamentals of a company are perceived to be deteriorating, the valuation of the underlying company relative to its future growth rate appears to have become excessive, or when more attractive alternative investments surface. Sentinel may also sell Fund holdings to meet redemptions.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

You could lose money by investing in the Fund. The following is a summary description of the principal risks of investing in the Fund:

· Foreign Banks and Securities Depositories Risk. Some foreign banks and securities depositories in which the Fund generally holds its foreign securities may be recently organized or new to the foreign custody business. In addition, there may be limited or no regulatory oversight over their operations. Also, the laws of certain countries may put limits on the Fund’s ability to recover its assets if a foreign bank, depository or issuer of a security, or any of their agents, goes bankrupt.

· General Foreign Securities Risk. Investments in foreign securities may be affected unfavorably by changes in currency rates or exchange control regulations, or political and/or social instability in a particular foreign country or region.

· Investment Style Risk. The Fund’s growth style of investing may be out of favor at any particular time. The stocks of growth companies may be more sensitive to investor perceptions about company earnings than other stocks and may be more volatile than the market in general.

· Non-Diversified Risk. The Fund is a non-diversified fund, meaning that it may hold fewer securities than a diversified portfolio and may take larger positions in individual securities. As a result, the Fund may be more affected by the performance of a particular security than a fund investing in a broader range of securities.

· Sector Risk. Investments in a particular sector may trail returns from other economic sectors.

· Stock Market and Selection Risk. The stock market may go down in value, and may go down sharply and unpredictably. The stocks selected by the portfolio manager may underperform the stock market or other funds with similar investment objectives and investment strategies.

The following bar chart and table provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for 1, 5 and 10 years compare with those of broad measures of market performance. The bar chart shows changes in the Fund’s performance for Class A shares for each calendar year over a ten-year period. Sales charges are not reflected in the bar chart. If sales charges were reflected, returns would be less than those shown. However, the table includes, for share classes with a sales charge, the effect of the maximum sales charge, including any contingent deferred sales charge that would apply to a redemption at the end of the period. How the Fund performed in the past (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated information on the Fund’s results can be obtained by visiting www.sentinelinvestments.com.

The Sentinel Growth Leaders Fund began operations on March 17, 2006. Performance for the Fund prior to March 17, 2006 is based on the performance of its predecessor, the Bramwell Focus Fund, which was offered without a sales charge. Performance of Class A shares reflects the current maximum sales charge. Performance of the Class A shares from their inception on March 17, 2006 to June 29, 2012, has not been adjusted to reflect the lower maximum 12b-1 fee in effect prior to March 17, 2006 or the decrease in the maximum 12b-1 fee, effective June 30, 2012, from 0.30% to 0.25%. If it had, those returns would be higher. Performance of Class C shares prior to March 17, 2006 (the inception date for the Class C shares) has been adjusted for the higher estimated expenses of those shares. Performance of the Class I shares from March 17, 2006 to August 27, 2007 (the inception date for the Class I shares) is based on the Fund’s Class A shares, restated to reflect that Class I shares are offered without a sales charge.

[1] The Standard & Poor's 500 Index consists of 500 widely held U.S. equity securities chosen for market size, liquidity, and industry group representation. The Fund compares its performance to this index because Fund management believes it is an appropriate alternative measure of the Fund's investment strategy.

[3] 12b-1 fees have been restated to reflect a reduction in the maximum fee from 0.30% to 0.25% effective June 30, 2012. Because of this restatement, the Total Annual Fund Operating Expenses do not correlate to the ratio of expenses to average net assets shown in the Fund's most recent annual report.

[4] The Fund's investment adviser has contractually agreed, effective March 30, 2013, to waive fees and/or reimburse certain expenses in order to limit Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement for Class A shares, on an annualized basis, to 1.45% of average daily net assets attributable to Class A shares through March 31, 2014. This agreement may be terminated upon 90 days' notice by a majority of the non-interested directors of the Fund.

[5] Return after taxes on distributions and sale of fund shares may be higher than return before taxes and/or return after taxes on distributions when a net capital loss occurs upon the redemption of fund shares.

[6] 12b-1 fees have been restated from fiscal year amounts to reflect the maximum fee payable under the applicable distribution plan for such share class. 12b-1 fees are not assessed with respect to shares owned by NLV Financial Corporation or an affiliate ("NLVFin"), which may result in an overall distribution fee charged to all shareholders of less than the maximum for so long as the NLVFin investment is maintained.

Strategy [Heading]

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund normally invests at least 80% of its total assets in municipal securities that generate income that, in the opinion of counsel to the issuer of the security, is exempt from federal and Georgia state income taxes.

The Fund may invest in municipal obligations whose interest is a tax-preference item for purposes of the federal alternative minimum tax (“AMT”). If you are subject to the AMT, a portion of the Fund’s distributions to you may not be exempt from federal income tax.

The Fund’s investment sub-adviser will purchase investment-grade municipal securities in an attempt to maintain an average weighted portfolio maturity of five to fifteen years, as determined by market conditions. As a core, general obligation, revenue, school, housing, hospital development and insured municipal bonds are represented. GLOBALT considers the relative yield, maturity and availability of various types of municipal bonds and the general economic outlook in determining how much to invest in a specific type of municipal bond in the Fund’s portfolio. Duration adjustments are made relative to the Barclays 10-Year Municipal Bond Index.

The Fund is “non-diversified,” which means that the Fund may concentrate its assets in a smaller number of issuers than a diversified fund, thus increasing the importance of each holding.

Risk [Heading]

rr_RiskHeading

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

You could lose money by investing in the Fund. The following is a summary description of the principal risks of investing in the Fund:

· General Fixed-Income Securities Risk. The market prices of bonds, including those issued by the U.S. government, go up as interest rates fall, and go down as interest rates rise. As a result, the net asset value of the shares of Funds holding bonds will fluctuate with conditions in the bond markets.

· Municipal Lease Risk. Municipal leases contain non-appropriation clauses under which the municipality may elect annually not to appropriate funds for future lease payments. As a result, the Fund may not receive payments from a lease obligation as originally anticipated.

· Non-Diversified Risk. Because the Fund holds fewer securities than a diversified portfolio and may take larger positions in individual securities, the Fund may be more affected by the performance of any particular security.

· Related Projects Risk. The Fund invests in issuers that finance similar types of municipal projects and obligors whose principal business activities are in the same types of municipal projects. As a result, the value of the Fund’s shares may be adversely affected by the effects of economic, political, tax law or business developments related to the municipal projects.

· State-Specific Risk. The Fund is more susceptible to factors adversely affecting Georgia governmental entities than a municipal bond fund that is diversified nationally. Changes in the economic condition and governmental policies of the State of Georgia may cause the value of the Fund’s shares to fall.

· Taxability Risk. While the Fund seeks to invest in municipal bonds whose interest payments will be excludable from gross income for federal income tax purposes, a municipal bond may be reclassified as taxable by the Internal Revenue Service. In addition, future legislative, administrative or court actions may cause interest on municipal bonds to be subject to federal income taxation, subjecting an investor to increased tax liability and/or adversely impacting the value of the security.

· U.S. Territory-Specific Risk. The Fund is susceptible to factors adversely affecting certain U.S. territories that issue securities that may be exempt from federal, and in certain circumstances, state and local taxes.

Strategy [Heading]

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund normally invests at least 80% of its net assets in mid-capitalization companies. For this purpose, mid-capitalization companies are companies that have, at the time of purchase, market capitalizations between $500 million and $25 billion. The Fund seeks to invest primarily in common stocks of mid-capitalization companies that Sentinel believes are high quality, have superior business models, solid management teams, sustainable growth potential and are attractively valued. The Fund may invest without limitation in foreign securities, although only where the securities are trading in the U.S. or Canada and only where trading is denominated in U.S. or Canadian dollars.

Up to 25% of the Fund’s assets may be invested in securities within a single industry. For portfolio construction purposes, the Fund uses the Standard & Poor’s MidCap 400 Index as a sector-weighting guide, generally using a plus or minus 25% weighting. The Fund attempts to be well-balanced across major economic sectors. Although the Fund may invest in any economic sector, at times it may emphasize one or more particular sectors.

The Fund would typically sell a security if the portfolio managers believe it is overvalued, if the original investment premise is no longer true, if the market cap exceeds a specified threshold and/or if the holding size exceeds the portfolio managers’ company or sector weighting guidelines. The Fund may also sell a partial position in a security in order to manage the size of the position. A security may also be sold to meet redemptions.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

You could lose money by investing in the Fund. The following is a summary description of the principal risks of investing in the Fund:

· General Foreign Securities Risk. Investments in foreign securities may be affected unfavorably by changes in currency rates or exchange control regulations, or political and/or social instability in a particular foreign country or region.

· Investment Style Risk. The Fund’s growth style of investing may be out of favor at any particular time. The stocks of growth companies may be more sensitive to investor perceptions about company earnings than other stocks and may be more volatile than the market in general.

· Sector Risk. Investments in a particular sector may trail returns from other economic sectors.

· Stock Market and Selection Risk. The stock market may go down in value, and may go down sharply and unpredictably. The stocks selected by the portfolio manager may underperform the stock market or other funds with similar investment objectives and investment strategies.

· Stocks of Smaller Companies Risk. The stocks of small- and/or mid-capitalization companies in which the Fund invests typically involve more risk than the stocks of larger companies. These smaller companies may have more limited financial resources and product lines, and may have less seasoned managers. In addition, these stocks may trade less frequently and in lower share volumes, making them subject to wider price fluctuations.

The following bar chart and table provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for 1, 5 and 10 years compare with those of broad measures of market performance. The bar chart shows changes in the Fund’s performance for Class A shares for each calendar year over a ten-year period. Sales charges are not reflected in the bar chart. If sales charges were reflected, returns would be less than those shown. However, the table includes, for share classes with a sales charge, the effect of the maximum sales charge, including any contingent deferred sales charge that would apply to a redemption at the end of the period. How the Fund performed in the past (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated information on the Fund’s results can be obtained by visiting www.sentinelinvestments.com.

Performance of the Class A shares prior to June 30, 2012, has not been adjusted to reflect the decrease in the maximum 12b-1 fee from 0.30% to 0.25%. If it had, those returns would be higher. Performance of the Class I shares prior to August 27, 2007 (the inception date for the Class I shares) is based on the Fund’s Class A share performance, restated to reflect that Class I shares are offered without a sales charge.

Sentinel Balanced Fund

Investment Objective

The Fund seeks a combination of growth of capital and current income, with relatively low risk and relatively low fluctuations in value.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $25,000 in shares of the Sentinel Funds that include Class A shares. More information about these and other discounts is available from your financial professional and in the section entitled “Share Classes” on page 98 of the Fund’s prospectus and “How to Purchase Shares and Reduce Sales Charges” on page 52 of the Fund’s statement of additional information.

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same.

Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Expense Example Sentinel Balanced Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Class A	605	826	1,066	1,751
Class C	297	609	1,047	2,264
CLASS I	110	343	595	1,317

You would pay the following expenses if you did not redeem your shares:

Expense Example No Redemption (USD $)	1 Year	3 Years	5 Years	10 Years
Sentinel Balanced Fund Class C	197	609	1,047	2,264

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 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 146% of the average value of its portfolio.

Principal Investment Strategies

The Fund normally invests primarily in common stocks and investment-grade bonds with at least 25% of its assets in bonds and at least 25% of its assets in common stock. When determining this percentage, convertible bonds and/or preferred stocks are considered common stocks, unless these securities are held primarily for income. Sentinel will divide the Fund’s assets among stocks and bonds based on whether it believes stocks or bonds offer a better value at the time. More bonds normally enhance price stability, and more stocks usually enhance growth potential. Up to 25% of the Fund’s assets may be invested in securities within a single industry.

With respect to equities, Sentinel’s investment philosophy centers on building a diverse portfolio consisting largely of securities of high quality companies with a positive multi year outlook offered at attractive valuation levels, based on a number of metrics, including value relative to its history, peers and/or the market over time. Although the Fund may invest in any economic sector, at times it may emphasize one or more particular sectors. Sentinel has a preference for companies that earn above-average rates of return on capital and that generate free cash flow. Additionally, earnings revision trends are important. The Fund may invest without limitation in foreign securities. Under normal circumstances, the equity securities in which the Fund invests are predominantly those of U.S companies.

The bond portion of the Fund may be invested without limitation in bonds in the first through the fourth highest rating categories of Moody’s (Aaa to Baa) and Standard and Poor’s (AAA to BBB). No more than 20% of the Fund’s total assets may be invested in lower-quality bonds (e.g., bonds rated below Baa by Moody’s or BBB by Standard & Poor’s). These lower-quality bonds have speculative characteristics. The Fund will only purchase securities rated B3 or lower by Moody’s or lower than B- by Standard and Poor’s if Sentinel believes the quality of the bonds is higher than indicated by the rating. The Fund may also purchase unrated bonds.

The Fund may make unlimited investments in U.S. government mortgage-backed securities issued and/or guaranteed by the Federal National Mortgage Association (“FNMA” or “Fannie Mae”), the Federal Home Loan Mortgage Corporation (“FHLMC” or “Freddie Mac”) and by the Government National Mortgage Association (“GNMA” or “Ginnie Mae”). While the original maximum life of a mortgage-backed security considered for this Fund can vary, its average life is likely to be substantially less than the original maturity of the underlying mortgages, because the mortgages in these pools may be prepaid, refinanced, curtailed, or foreclosed. Prepayments are passed through to the mortgage-backed security holder along with regularly scheduled minimum repayments of principal and payments of interest.

The Fund may attempt to hedge various risks, such as interest rate risk, using derivative instruments (e.g., exchange-traded futures and options, and other derivatives such as swaps, options on swaps, and caps and floors), and may use derivative instruments for other investment purposes such as replicating permitted investments, as long as such investments do not have the effect of leveraging portfolio risks. The Fund is not required to use hedging and may choose not to do so.

In managing the fixed-income portion of the portfolio, the Fund utilizes an active trading approach, which may result in portfolio turnover greater than 100%.

The Fund may sell a security if the fundamentals of the company are deteriorating or the original investment premise is no longer valid, the security is trading meaningfully higher than what the portfolio manager believes is a fair valuation, to manage the size of the holding or the sector weighting and/or to take advantage of a more attractive investment opportunity. The Fund may also sell a security to meet redemptions.

Principal Investment Risks

You could lose money by investing in the Fund. The following is a summary description of the principal risks of investing in the Fund:

· Asset Allocation Risk The Fund’s allocations to the various asset classes and market sectors could cause the Fund to underperform other funds with a similar investment objective.

· Derivatives Risk. Derivative investments involve counterparty risk (the risk that the counterparty of the derivative transaction will be unable to honor its financial obligation to the Fund), basis risk (the risk that the derivative instrument will not fully offset the underlying positions), and liquidity risk (the risk that the Fund cannot sell the derivative instrument because of an illiquid secondary market). In addition, the portfolio manager may incorrectly forecast the values of securities, currencies or interest rates or other economic factors in using derivatives for the Fund.

· Foreign Banks and Securities Depositories Risk. Some foreign banks and securities depositories in which the Fund generally holds its foreign securities may be recently organized or new to the foreign custody business. In addition, there may be limited or no regulatory oversight over their operations. Also, the laws of certain countries may put limits on the Fund’s ability to recover its assets if a foreign bank, depository or issuer of a security, or any of their agents, goes bankrupt.

· General Fixed-Income Securities Risk. The market prices of bonds, including those issued by the U.S. government, go up as interest rates fall, and go down as interest rates rise. As a result, the net asset value of the Fund will fluctuate with conditions in the bond markets. In the case of corporate bonds and commercial paper, values may fluctuate as perceptions of credit quality change. In addition, corporate bonds may be downgraded or default. During periods of declining interest rates or for other reasons, bonds may be “called”, or redeemed, by the bond issuer prior to the bond’s maturity date, resulting in the Fund receiving payment earlier than expected. This may reduce the Fund’s income if the proceeds are reinvested at a lower interest rate.

· General Foreign Securities Risk. Investments in foreign securities may be affected unfavorably by changes in currency rates or exchange control regulations, or political and/or social instability in a particular foreign country or region.

· Government Securities Risk. Economic, business, or political developments may affect the ability of government-sponsored guarantors to repay principal and to make interest payments on the securities in which the Fund invests. In addition, certain of these securities, including those issued or guaranteed by FNMA and FHLMC, are not backed by the full faith and credit of the U.S. government.

· Investment Style Risk. The Fund uses a “blend” strategy to invest in both growth and value stocks, and/or in stocks with characteristics of both. This strategy may be out of favor at any particular time. The prices of growth stocks may fall dramatically if the company fails to meet earnings or revenue projections. The prices of value stocks may lag the stock market for long periods of time if the market fails to recognize the company’s intrinsic worth.

· Lower-Quality Bonds Risk. Bonds with lower credit ratings are more speculative and likely to default than higher-quality bonds. Lower-rated bonds also tend to fluctuate more widely in value.

· Mortgage-Backed Securities Risk. Mortgage-backed securities represent interests in “pools” of mortgages and are subject to certain additional risks. When interest rates rise, certain obligations will be paid off by the obligor more slowly than anticipated causing the value of these securities to fall. This is known as extension risk. In addition, adjustable and fixed rate mortgage-related securities are subject to prepayment risk. When interest rates decline, borrowers may pay off their mortgages sooner than expected. This can reduce the returns of the Fund because the Fund may have to reinvest that money at the lower prevailing interest rates. These securities also are subject to risk of default on the underlying mortgage, particularly during periods of economic downturn.

· Portfolio Turnover Risk. An active trading approach increases the Fund’s costs and may reduce the Fund’s performance. It may also increase the amount of capital gains tax that you have to pay on the Fund’s returns.

· Sector Risk. Investments in a particular sector may trail returns from other economic sectors.

· Stock Market and Selection Risk. The stock market may go down in value, and may go down sharply and unpredictably. The stocks selected by the portfolio manager may underperform the stock market or other funds with similar investment objectives and investment strategies.

Performance

The following bar chart and table provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for 1, 5 and 10 years compare with those of broad measures of market performance. The bar chart shows changes in the Fund’s performance for Class A shares for each calendar year over a ten-year period. Sales charges are not reflected in the bar chart. If sales charges were reflected, returns would be less than those shown. However, the table includes, for share classes with a sales charge, the effect of the maximum sales charge, including any contingent deferred sales charge that would apply to a redemption at the end of the period. How the Fund performed in the past (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated information on the Fund’s results can be obtained by visiting www.sentinelinvestments.com.

Performance of the Class A shares prior to June 30, 2012, has not been adjusted to reflect the decrease in the maximum 12b-1 fee from 0.30% to 0.25%. If it had, those returns would be higher. Performance of the Class I shares prior to August 27, 2007 (the inception date for the Class I shares) is based on the Fund’s Class A share performance, restated to reflect that Class I shares are offered without a sales charge.

Investment Objective

The Fund seeks long-term capital appreciation.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $25,000 in shares of the Sentinel Funds that include Class A shares. More information about these and other discounts is available from your financial professional and in the section entitled “Share Classes” on page 98 of the Fund’s prospectus and “How to Purchase Shares and Reduce Sales Charges” on page 52 of the Fund’s statement of additional information.

Shareholder Fees (fees paid directly from your investment)

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same.

Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Expense Example Sentinel Sustainable Core Opportunities Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Class A	625	889	1,172	1,979
Class I	106	331	574	1,271

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 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 4% of the average value of its portfolio.

Principal Investment Strategies

The Fund normally invests at least 65% of its net assets in stocks of well-established U.S. companies, typically those above $5 billion in market capitalization. The Fund may invest without limitation in foreign securities.

Sentinel’s investment philosophy centers on building a diverse portfolio consisting largely of securities of high quality companies with a positive multi-year outlook offered at attractive valuation levels, based on a number of metrics, including value relative to its history, peers and/or the market over time. The Fund may also invest in stocks with the potential to provide current income, growth of income and relatively low risk as compared to the stock market as a whole when consistent with the Fund’s investment objective.

Up to 25% of the Fund’s assets may be invested in securities within a single industry. Although the Fund may invest in any economic sector, at times it may emphasize one or more particular sectors. Sentinel has a preference for companies that earn above-average rates of return on capital and that generate free cash flow. Additionally, earnings revision trends are important.

The Fund may sell a security if the fundamentals of the company are deteriorating or the original investment premise is no longer valid, the stock is trading meaningfully higher than what the portfolio manager believes is a fair valuation, to manage the size of the holding or the sector weighting and/or to take advantage of a more attractive investment opportunity, and to meet redemptions. A security will also be sold if it is determined that it no longer meets the environmental, social and/or corporate governance performance criteria.

Sustainable and Responsible Investing. The Fund employs a process of environmental, social and corporate governance (“ESG”) screening that is overseen by Sentinel’s in-house sustainable research department. While no investment is ever made solely based on the qualitative criteria alone, the Fund believes sustainable screening provides a unique and more comprehensive view of the companies it considers for investment. Generally, companies are eliminated from investment consideration if they produce tobacco or tobacco products or alcoholic beverages; generate nuclear power or supply nuclear facilities with industry specific components, as a primary line of business; have material interests in the manufacture of weapons or weapons-specific components; are involved in gambling as a main line of business; and/or lack diversity at the level of the board of directors/senior management. The Fund favors companies that publish and enforce codes of conduct and vendor standards; promote equal opportunity, diversity and good employee relations; are sensitive to community concerns; seek alternatives to animal testing when not required by law; and/or have minimal impact on the environment and engage in proactive environmental initiatives.

Sentinel may, in its discretion, choose to apply additional screens, modify the application of the screens listed above or vary the application of the screens listed above to the Funds’ investments at any time without shareholder approval.

For additional information on the environmental, social and governance screening process used by the Fund, please see “Additional Information About Each Fund — Investment Objectives and Strategies — Sentinel Sustainable Core Opportunities Fund — Principal Investment Strategies” at page 86 of the Prospectus.

Principal Investment Risks

· Foreign Banks and Securities Depositories Risk. Some foreign banks and securities depositories in which the Fund generally holds its foreign securities may be recently organized or new to the foreign custody business. In addition, there may be limited or no regulatory oversight over their operations. Also, the laws of certain countries may put limits on the Fund’s ability to recover its assets if a foreign bank, depository or issuer of a security, or any of their agents, goes bankrupt.

· General Foreign Securities Risk. Investments in foreign securities may be affected unfavorably by changes in currency rates or exchange control regulations, or political and/or social instability in a particular foreign country or region.

· Investment Style Risk. The Fund uses a “blend” strategy to invest in both growth and value stocks, and/or in stocks with characteristics of both. This strategy may be out of favor at any particular time. The prices of growth stocks may fall dramatically if the company fails to meet earnings or revenue projections. The prices of value stocks may lag the stock market for long periods of time if the market fails to recognize the company’s intrinsic worth.

· Sector Risk. Investments in a particular sector may trail returns from other economic sectors.

· Stock Market and Selection Risk. The stock market may go down in value, and may go down sharply and unpredictably. The stocks selected by the portfolio manager may underperform the stock market or other funds with similar investment objectives and investment strategies.

· Sustainable/Responsible Investing Risk. The Fund’s environmental, social and corporate governance criteria may cause the Fund to forgo opportunities to buy certain securities, and/or forgo opportunities to gain exposure to certain industries, sectors, regions and countries. In addition, the Fund may be required to sell a security when it might otherwise be disadvantageous for it to do so.

Performance

The following bar chart and table provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for 1, 5 and 10 years compare with those of broad measures of market performance. The bar chart shows changes in the Fund’s performance for Class A shares for each calendar year over a ten-year period. Sales charges are not reflected in the bar chart. If sales charges were reflected, returns would be less than those shown. However, the table includes, for share classes with a sales charge, the effect of the maximum sales charge. How the Fund performed in the past (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated information on the Fund’s results can be obtained by visiting www.sentinelinvestments.com.

The Sentinel Sustainable Core Opportunities Fund, which began operations on April 4, 2008, is a successor to the Citizens Value Fund, which was a successor to the Meyers Pride Value Fund, which began operations on June 13, 1996. Performance for the Class A shares of the Fund from September 24, 2001 to April 4, 2008 is based on the performance of the Standard shares of the predecessor Citizens Value Fund, which was offered without a sales charge and reflects the current maximum sales charge. Performance of the Class A shares from their inception on April 4, 2008 to June 29, 2012, has not been adjusted to reflect the lower maximum 12b-1 fee in effect prior to April 4, 2008 or the decrease in the maximum 12b-1 fee, effective June 30, 2012, from 0.30% to 0.25%. If it had, those returns would be higher. Performance of the Class I shares from March 31, 2006 to April 4, 2008 (the inception date for the Class I shares) is based on the performance of the Institutional shares of the Citizens Value Fund, which had different expenses but substantially similar investment risks and from September 24, 2001 to March 31, 2006 is based on the performance of the Standard shares of the Citizens Value Fund.

Inception: 1996 (the inception of the Fund’s predecessor)

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same.

Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Expense Example Sentinel Mid Cap Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Class A	633	915	1,217	2,075

Expense Example No Redemption (USD $)	1 Year	3 Years	5 Years	10 Years
Sentinel Mid Cap Fund Class C	270	829	1,415	3,003

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 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 25% of the average value of its portfolio.

Principal Investment Strategies

The Fund normally invests at least 80% of its net assets in mid-capitalization companies. For this purpose, mid-capitalization companies are companies that have, at the time of purchase, market capitalizations between $500 million and $25 billion. The Fund seeks to invest primarily in common stocks of mid-capitalization companies that Sentinel believes are high quality, have superior business models, solid management teams, sustainable growth potential and are attractively valued. The Fund may invest without limitation in foreign securities, although only where the securities are trading in the U.S. or Canada and only where trading is denominated in U.S. or Canadian dollars.

Up to 25% of the Fund’s assets may be invested in securities within a single industry. For portfolio construction purposes, the Fund uses the Standard & Poor’s MidCap 400 Index as a sector-weighting guide, generally using a plus or minus 25% weighting. The Fund attempts to be well-balanced across major economic sectors. Although the Fund may invest in any economic sector, at times it may emphasize one or more particular sectors.

The Fund would typically sell a security if the portfolio managers believe it is overvalued, if the original investment premise is no longer true, if the market cap exceeds a specified threshold and/or if the holding size exceeds the portfolio managers’ company or sector weighting guidelines. The Fund may also sell a partial position in a security in order to manage the size of the position. A security may also be sold to meet redemptions.

Principal Investment Risks

You could lose money by investing in the Fund. The following is a summary description of the principal risks of investing in the Fund:

· General Foreign Securities Risk. Investments in foreign securities may be affected unfavorably by changes in currency rates or exchange control regulations, or political and/or social instability in a particular foreign country or region.

· Investment Style Risk. The Fund’s growth style of investing may be out of favor at any particular time. The stocks of growth companies may be more sensitive to investor perceptions about company earnings than other stocks and may be more volatile than the market in general.

· Sector Risk. Investments in a particular sector may trail returns from other economic sectors.

· Stock Market and Selection Risk. The stock market may go down in value, and may go down sharply and unpredictably. The stocks selected by the portfolio manager may underperform the stock market or other funds with similar investment objectives and investment strategies.

· Stocks of Smaller Companies Risk. The stocks of small- and/or mid-capitalization companies in which the Fund invests typically involve more risk than the stocks of larger companies. These smaller companies may have more limited financial resources and product lines, and may have less seasoned managers. In addition, these stocks may trade less frequently and in lower share volumes, making them subject to wider price fluctuations.

Performance

The following bar chart and table provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for 1, 5 and 10 years compare with those of broad measures of market performance. The bar chart shows changes in the Fund’s performance for Class A shares for each calendar year over a ten-year period. Sales charges are not reflected in the bar chart. If sales charges were reflected, returns would be less than those shown. However, the table includes, for share classes with a sales charge, the effect of the maximum sales charge, including any contingent deferred sales charge that would apply to a redemption at the end of the period. How the Fund performed in the past (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated information on the Fund’s results can be obtained by visiting www.sentinelinvestments.com.

Performance of the Class A shares prior to June 30, 2012, has not been adjusted to reflect the decrease in the maximum 12b-1 fee from 0.30% to 0.25%. If it had, those returns would be higher. Performance of the Class I shares prior to August 27, 2007 (the inception date for the Class I shares) is based on the Fund’s Class A share performance, restated to reflect that Class I shares are offered without a sales charge.

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund normally invests primarily in a broad range of common stocks of companies that Sentinel believes have above-average growth potential.

Sentinel attempts to identify companies that are expected to grow as a result of the potential long-term return from their investment in research, development, capital spending and market expansion. In addition, Sentinel looks for companies that it perceives to be attractively valued relative to their future growth prospects, as well as to that of the market as a whole. When selecting investments focus is on company-specific variables, such as competitive industry dynamics, market leadership, proprietary products and services, and management expertise, as well as on financial characteristics, such as returns on sales and equity, debt/equity ratios and earnings and cash flow growth. Sentinel also analyzes a company’s dividend-paying characteristics when selecting investments with respect to the Fund’s current income objective.

The Fund may invest in any economic sector, and at times may emphasize one or more particular sectors. The Fund may invest up to 25% of its net assets in a single industry. The Fund may invest up to 25% of its net assets in securities of foreign issuers, although only where the securities are trading in the U.S. or Canada and only where trading is denominated in U.S. or Canadian dollars.

Sentinel expects to sell Fund holdings when the fundamentals of a company are perceived to be deteriorating, the valuation of the underlying company relative to its future growth rate appears to have become excessive, or when more attractive alternative investments surface. Sentinel may also sell Fund holdings to meet redemptions.

The following bar chart and table provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for 1, 5 and 10 years compare with those of broad measures of market performance. The bar chart shows changes in the Fund’s performance for Class A shares for each calendar year over a ten-year period. Sales charges are not reflected in the bar chart. If sales charges were reflected, returns would be less than those shown. However, the table includes, for share classes with a sales charge, the effect of the maximum sales charge, including any contingent deferred sales charge that would apply to a redemption at the end of the period.

Updated information on the Fund’s results can be obtained by visiting www.sentinelinvestments.com.

The Sentinel Capital Growth Fund began operations on March 17, 2006. Performance for the Fund prior to March 17, 2006 is based on the performance of its predecessor, the Bramwell Growth Fund, which was offered without a sales charge. Performance of Class A shares reflects the current maximum sales charge. Performance of the Class A shares from their inception on March 17, 2006 to June 29, 2012, has not been adjusted to reflect the lower maximum 12b-1 fee in effect prior to March 17, 2006 or the decrease in the maximum 12b-1 fee, effective June 30, 2012, from 0.30% to 0.25%. If it had, those returns would be higher. Performance of Class C shares prior to their inception on March 17, 2006 has been adjusted for the higher estimated expenses of those shares. Performance of the Class I shares from March 17, 2006 to August 27, 2007 (the inception date for the Class I shares) is based on the Fund’s Class A shares, restated to reflect that Class I shares are offered without a sales charge.

Sentinel Sustainable Mid Cap Opportunities Fund

Investment Objective

The Fund seeks growth of capital.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $25,000 in shares of the Sentinel Funds that include Class A shares. More information about these and other discounts is available from your financial professional and in the section entitled “Share Classes” on page 98 of the Fund’s prospectus and “How to Purchase Shares and Reduce Sales Charges” on page 52 of the Fund’s statement of additional information.

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees Sentinel Sustainable Mid Cap Opportunities Fund	Class A		Class I
Maximum Sales Charge (Load) Imposed on Purchases (as a percentage of offering price)	5.00%		none
Maximum Deferred Sales Charge (Load)(as a percentage of purchase price or redemption proceeds, whichever is less)	none	[1]	none
Redemption Fees (as a percentage of amounts redeemed or exchanged within 30 days)	none		none

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses Sentinel Sustainable Mid Cap Opportunities Fund	Class A		Class I
Management Fee	0.70%		0.70%

Total Annual Fund Operating Expenses	1.38%		1.33%

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same.

Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Expense Example Sentinel Sustainable Mid Cap Opportunities Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Class A	633	915	1,217	2,075
Class I	135	421	729	1,601

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 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 117% of the average value of its portfolio.

Principal Investment Strategies

The Fund normally invests at least 80% of its net assets in mid-capitalization companies. For this purpose, mid-capitalization companies are companies that have, at the time of purchase, market capitalizations between $500 million and $25 billion. The Fund seeks to invest primarily in common stocks of mid-capitalization companies that Sentinel believes are high quality, have superior business models, solid management teams, sustainable growth potential and are attractively valued. The Fund may invest without limitation in foreign securities, although only where the securities are trading in the U.S. or Canada and only where trading is denominated in U.S. or Canadian dollars.

Up to 25% of the Fund’s assets may be invested in securities within a single industry. For portfolio construction purposes, the Fund uses the Standard & Poor’s MidCap 400 Index as a sector-weighting guide, generally using a plus or minus 25% weighting. The Fund attempts to be well-balanced across major economic sectors. Although the Fund may invest in any economic sector, at times it may emphasize one or more particular sectors.

The Fund would typically sell a security if the portfolio managers believe it is overvalued, if the original investment premise is no longer true, if the market cap exceeds a specified threshold and/or if the holding size exceeds the portfolio managers’ company or sector weighting guidelines. The Fund may also sell a partial position in a security in order to manage the size of the position. A security may also be sold to meet redemptions. A security will be sold when it is determined that it no longer meets the environmental, social and/or corporate governance performance criteria.

Sustainable and Responsible Investing. The Fund employs a process of environmental, social and corporate governance (“ESG”) screening that is overseen by Sentinel’s in-house sustainable research department. While no investment is ever made solely based on the qualitative criteria alone, the Fund believes sustainable screening provides a unique and more comprehensive view of the companies it considers for investment. Generally, companies are eliminated from investment consideration if they produce tobacco or tobacco products or alcoholic beverages; generate nuclear power or supply nuclear facilities with industry specific components, as a primary line of business; have material interests in the manufacture of weapons or weapons-specific components; are involved in gambling as a main line of business; and/or lack diversity at the level of the board of directors/senior management. The Fund favors companies that publish and enforce codes of conduct and vendor standards; promote equal opportunity, diversity and good employee relations; are sensitive to community concerns; seek alternatives to animal testing when not required by law; and/or have minimal impact on the environment and engage in proactive environmental initiatives.

Sentinel may, in its discretion, choose to apply additional screens, modify the application of the screens listed above or vary the application of the screens listed above to the Funds’ investments at any time without shareholder approval.

For additional information on the environmental, social and governance screening process used by the Fund, please see “Additional Information About Each Fund — Investment Objectives and Strategies — Sentinel Sustainable Mid Cap Opportunities Fund — Principal Investment Strategies” at page 88 of the Prospectus.

Principal Investment Risks

You could lose money by investing in the Fund. The following is a summary description of the principal risks of investing in the Fund:

· General Foreign Securities Risk. Investments in foreign securities may be affected unfavorably by changes in currency rates or exchange control regulations, or political and/or social instability in a particular foreign country or region.

· Investment Style Risk. The Fund’s growth style of investing may be out of favor at any particular time. The stocks of growth companies may be more sensitive to investor perceptions about company earnings than other stocks and may be more volatile than the market in general.

· Sector Risk. Investments in a particular sector may trail returns from other economic sectors.

· Stock Market and Selection Risk. The stock market may go down in value, and may go down sharply and unpredictably. The stocks selected by the portfolio manager may underperform the stock market or other funds with similar investment objectives and investment strategies.

·  Stocks of Smaller Companies Risk. The stocks of small- and mid-capitalization companies in which the Fund invests typically involve more risk than the stocks of larger companies. These smaller companies may have more limited financial resources, narrower product lines, and may have less seasoned managers. In addition, these stocks may trade less frequently and in lower share volumes, making them subject to wider price fluctuations.

· Sustainable/Responsible Investing Risk. The Fund’s environmental, social and corporate governance criteria may cause the Fund to forgo opportunities to buy certain securities, and/or forgo opportunities to gain exposure to certain industries, sectors, regions and countries. In addition, the Fund may be required to sell a security when it might otherwise be disadvantageous for it to do so.

Performance

The following bar chart and table provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for 1, 5 and 10 years compare with those of broad measures of market performance. The bar chart shows changes in the Fund’s performance for Class A shares for each calendar year over a ten-year period. Sales charges are not reflected in the bar chart. If sales charges were reflected, returns would be less than those shown. However, the table includes, for share classes with a sales charge, the effect of the maximum sales charge. How the Fund performed in the past (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated information on the Fund’s results can be obtained by visiting www.sentinelinvestments.com.

The Sentinel Sustainable Mid Cap Opportunities Fund, which began operations on April 4, 2008, is a successor to the Citizens Emerging Growth Fund, which began operations on February 8, 1994. Performance for the Class A shares of the Fund prior to April 4, 2008 is based on the performance of the Standard shares of the Citizens Emerging Growth Fund, which was offered without a sales charge, and has been restated to reflect the current maximum sales charge. Performance of the Class A shares from their inception on April 4, 2008 to June 29, 2012, has not been adjusted to reflect the lower maximum 12b-1 fee in effect prior to April 4, 2008 or the decrease in the maximum 12b-1 fee, effective June 30, 2012, from 0.30% to 0.25%. If it had, those returns would be higher. Performance for the Class I shares from November 1, 1999 to April 4, 2008 is based on the performance of the Institutional shares of Citizens Emerging Growth Fund, which had different expenses but substantially similar investment risks.

After-tax returns are calculated using the historical highest applicable individual federal marginal income tax rates in effect during the relevant period and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. After-tax returns are shown only for Class A shares and after-tax returns for other classes of shares will vary.

[1] You pay a deferred sales charge of 1% on certain redemptions of Class A shares made within twelve months of purchase if you bought them without an initial sales charge as part of an investment of $1,000,000 or more.

[1] 12b-1 fees have been restated to reflect a reduction in the maximum fee from 0.30% to 0.25% effective June 30, 2012. Because of this restatement, the Total Annual Fund Operating Expenses do not correlate to the ratio of expenses to average net assets shown in the Fund's most recent annual report.

[1] Return after taxes on distributions and sale of fund shares may be higher than return before taxes and/or return after taxes on distributions when a net capital loss occurs upon the redemption of fund shares.

[2] The Standard & Poor's MidCap 400 Index measures the performance of the mid-sized company segment of the U.S. stock market. The market value-weighted index is based on 400 stocks chosen on the basis of market capitalization, liquidity and industry group representation. The Fund compares its performance to this index because Fund management believes it is an appropriate alternative measure of the Fund's investment strategy.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $25,000 in shares of the Sentinel Funds that include Class A shares. More information about these and other discounts is available from your financial professional and in the section entitled “Share Classes” on page 98 of the Fund’s prospectus and “How to Purchase Shares and Reduce Sales Charges” on page 52 of the Fund’s statement of additional information.

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same.

Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Expense Example Sentinel Common Stock Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Class A	603	820	1,056	1,729
Class C	296	606	1,042	2,254
CLASS I	77	240	417	930

You would pay the following expenses if you did not redeem your shares:

Expense Example No Redemption (USD $)	1 Year	3 Years	5 Years	10 Years
Sentinel Common Stock Fund Class C	196	606	1,042	2,254

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 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 8% of the average value of its portfolio.

Principal Investment Strategies

The Fund normally invests at least 80% of its net assets in common stocks. The Fund invests mainly in a diverse group of common stocks of well-established companies, typically above $5 billion in market capitalization, many of which historically have paid regular dividends. When appropriate, the Fund also may invest in preferred stocks or debentures convertible into common stocks. Up to 25% of the Fund’s assets may be invested in securities within a single industry. The Fund may invest without limitation in foreign securities. Under normal circumstances, the Fund invests predominantly in common stocks of U.S. companies.

Sentinel’s investment philosophy centers on building a diverse portfolio consisting largely of securities of high quality companies with a positive multi-year outlook offered at attractive valuation levels, based on a number of metrics, including value relative to its history, peers and/or the market over time. Although the Fund may invest in any economic sector, at times it may emphasize one or more particular sectors. Sentinel has a preference for companies that earn above-average rates of return on capital and that generate free cash flow. Additionally, earnings revision trends are important.

The Fund may sell a stock if the fundamentals of the company are deteriorating or the original investment premise is no longer valid, the stock is trading meaningfully higher than what the portfolio manager believes is a fair valuation, to manage the size of the holding or the sector weighting and/or to take advantage of a more attractive investment opportunity. A stock may also be sold to meet redemptions.

Principal Investment Risks

You could lose money by investing in the Fund. The following is a summary description of the principal risks of investing in the Fund:

· Foreign Banks and Securities Depositories Risk. Some foreign banks and securities depositories in which the Fund generally holds its foreign securities may be recently organized or new to the foreign custody business. In addition, there may be limited or no regulatory oversight over their operations. Also, the laws of certain countries may put limits on the Fund’s ability to recover its assets if a foreign bank, depository or issuer of a security, or any of their agents, goes bankrupt.

· General Foreign Securities Risk. Investments in foreign securities may be affected unfavorably by changes in currency rates or exchange control regulations, or political and/or social instability in a particular foreign country or region.

· Investment Style Risk. The Fund uses a “blend” strategy to invest in both growth and value stocks, and/or in stocks with characteristics of both. This strategy may be out of favor at any particular time. The prices of growth stocks may fall dramatically if the company fails to meet earnings or revenue projections. The prices of value stocks may lag the stock market for long periods of time if the market fails to recognize the company’s intrinsic worth.

· Sector Risk. Investments in a particular sector may trail returns from other economic sectors.

· Stock Market and Selection Risk. The stock market may go down in value, and may go down sharply and unpredictably. The stocks selected by the portfolio manager may underperform the stock market or other funds with similar investment objectives and investment strategies.

Performance

The following bar chart and table provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for 1, 5 and 10 years compare with those of broad measures of market performance. The bar chart shows changes in the Fund’s performance for Class A shares for each calendar year over a ten-year period. Sales charges are not reflected in the bar chart. If sales charges were reflected, returns would be less than those shown. However, the table includes, for share classes with a sales charge, the effect of the maximum sales charge, including any contingent deferred sales charge that would apply to a redemption at the end of the period. How the Fund performed in the past (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated information on the Fund’s results can be obtained by visiting www.sentinelinvestments.com.

Performance of the Class A shares prior to June 30, 2012, has not been adjusted to reflect the decrease in the maximum 12b-1 fee from 0.30% to 0.25%. If it had, those returns would be higher. Performance of the Class I shares prior to May 4, 2007 (the inception date for the Class I shares) is based on the Fund’s Class A share performance, restated to reflect that Class I shares are offered without a sales charge.

Inception: 1934

Annual Total Return for Class A Shares (%) as of December 31

During the ten-year period shown in the above bar chart, the highest return for a quarter was 17.88% (quarter ended June 30, 2003) and the lowest return for a quarter was -21.75% (quarter ended December 31, 2008).

Average Annual Total Return (%) For the periods ended December 31, 2012

Average Annual Returns Sentinel Common Stock Fund		Average Annual Returns, 1 Year	Average Annual Returns, 5 Years	Average Annual Returns, 10 Years
Class A		8.79%	1.01%	7.32%
Class C		12.60%	1.15%	6.83%
CLASS I		14.92%	2.43%	8.10%
After Taxes on Distributions Class A		8.11%	0.72%	6.50%
After Taxes on Distributions and Sale of Fund Shares Class A	[1]	6.61%	0.83%	6.19%
Standard & Poor’s 500 Index (Reflects no deduction for fees, expenses or taxes)		16.00%	1.66%	7.10%
Russell 1000® Index (Reflects no deduction for fees, expenses or taxes)	[2]	16.42%	1.92%	7.52%

After-tax returns are calculated using the historical highest applicable individual federal marginal income tax rates in effect during the relevant period and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. After-tax returns are shown only for Class A shares and after-tax returns for other classes of shares will vary.

[1] You pay a deferred sales charge of 1% on certain redemptions of Class A shares made within twelve months of purchase if you bought them without an initial sales charge as part of an investment of $1,000,000 or more.

[1] 12b-1 fees have been restated to reflect a reduction in the maximum fee from 0.30% to 0.25% effective June 30, 2012. Because of this restatement, the Total Annual Fund Operating Expenses do not correlate to the ratio of expenses to average net assets shown in the Fund's most recent annual report.

[1] Return after taxes on distributions and sale of fund shares may be higher than return before taxes and/or return after taxes on distributions when a net capital loss occurs upon the redemption of fund shares.

[2] The Russell 1000 Index measures the performance of the large-cap segment of the U.S. equity universe. The Fund compares its performance to this index because Fund management believes it is an appropriate alternative measure of the Fund's investment strategy.

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund normally invests at least 80% of its net assets in mid-capitalization companies. For this purpose, mid-capitalization companies are companies that have, at the time of purchase, market capitalizations between $500 million and $25 billion. The Fund seeks to invest primarily in common stocks of mid-capitalization companies that Sentinel believes are high quality, have superior business models, solid management teams, sustainable growth potential and are attractively valued. The Fund may invest without limitation in foreign securities, although only where the securities are trading in the U.S. or Canada and only where trading is denominated in U.S. or Canadian dollars.

Up to 25% of the Fund’s assets may be invested in securities within a single industry. For portfolio construction purposes, the Fund uses the Standard & Poor’s MidCap 400 Index as a sector-weighting guide, generally using a plus or minus 25% weighting. The Fund attempts to be well-balanced across major economic sectors. Although the Fund may invest in any economic sector, at times it may emphasize one or more particular sectors.

The Fund would typically sell a security if the portfolio managers believe it is overvalued, if the original investment premise is no longer true, if the market cap exceeds a specified threshold and/or if the holding size exceeds the portfolio managers’ company or sector weighting guidelines. The Fund may also sell a partial position in a security in order to manage the size of the position. A security may also be sold to meet redemptions.

· General Foreign Securities Risk. Investments in foreign securities may be affected unfavorably by changes in currency rates or exchange control regulations, or political and/or social instability in a particular foreign country or region.

· Investment Style Risk. The Fund’s growth style of investing may be out of favor at any particular time. The stocks of growth companies may be more sensitive to investor perceptions about company earnings than other stocks and may be more volatile than the market in general.

· Restricted and Illiquid Securities Risk. The Fund will not be able to readily resell illiquid securities and resale of some of these securities may be restricted by law or contractual provisions. The inability to sell these securities at the most opportune time may negatively affect the Fund’s net asset value.

· Sector Risk. Investments in a particular sector may trail returns from other economic sectors.

· Stocks of Smaller Companies Risk. The stocks of small- and/or mid-capitalization companies in which the Fund invests typically involve more risk than the stocks of larger companies. These smaller companies may have more limited financial resources and product lines, and may have less seasoned managers. In addition, these stocks may trade less frequently and in lower share volumes, making them subject to wider price fluctuations.

The Sentinel Mid Cap II Fund, which began operations on May 4, 2007, is a successor to the Synovus Mid Cap Value Fund, which was a successor to a similarly managed collective investment fund, which began operations on April 3, 2000. Performance for the Fund is based on the performance of its predecessors, which had different expenses but substantially similar investment risks. Performance from October 24, 2001 to May 4, 2007 is based on the Synovus Mid Cap Value Fund’s Class A, Class C or Institutional Class shares, as applicable, adjusted, in the case of Class A shares, for the current maximum sales charge. Performance of the Class A shares from their inception on May 4, 2007 to June 29, 2012, has not been adjusted to reflect the lower maximum 12b-1 fee in effect prior to May 4, 2007 or the decrease in the maximum 12b-1 fee, effective June 30, 2012, from 0.30% to 0.25%. If it had, those returns would be higher. Information for Class I shares is presented because the Class I share class has the longest period of annual returns.

Effective at the close of business on January 13, 2012, the Fund’s investment strategies were modified from a focus on value-style investing to a focus on investing in high quality companies with sustainable growth potential and attractive valuations, and the Fund changed its portfolio management team. The performance information provided below relates to the Fund’s investment strategies as implemented by the Fund’s sub-advisers prior to the close of business January 13, 2012.

Sentinel Total Return Bond Fund

Investment Objective

The Fund seeks maximum investment return through a combination of current income and capital appreciation.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $100,000 in shares of the Sentinel Funds that include Class A shares. More information about these and other discounts is available from your financial professional and in the section entitled “Share Classes” on page 98 of the Fund’s prospectus and “How to Purchase Shares and Reduce Sales Charges” on page 52 of the Fund’s statement of additional information.

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same.

Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Expense Example Sentinel Total Return Bond Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Class A	324	533	760	1,411
Class C	282	563	970	2,105
Class I	81	252	439	978

You would pay the following expenses if you did not redeem your shares:

Expense Example No Redemption (USD $)	1 Year	3 Years	5 Years	10 Years
Sentinel Total Return Bond Fund Class C	182	563	970	2,105

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 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 915 % of the average value of its portfolio.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by investing in fixed-income securities and in related derivatives, such as interest rate and foreign currency derivatives (futures, options, swaps, options on swaps, and caps and floors). The Fund invests primarily in investment-grade bonds. At least 80% of the Fund’s assets will normally be invested in the following types of bonds and related derivatives:

1. Corporate bonds of varying maturities issued by various U.S. and non-U.S. private-sector entities denominated in U.S. dollars and foreign currencies;

2. Debt securities issued or guaranteed by the U.S. government, its agencies or instrumentalities, including mortgage-backed securities, and by non-U.S. sovereign and quasi-sovereign entities; and

3. Taxable or tax-exempt municipal securities.

The Fund may invest in securities of any duration.

The Fund may invest up to 50% of its assets in below investment-grade bonds.

The Fund may use derivative instruments (e.g., exchange-traded derivatives such as futures and options, and other derivatives such as swap agreements, options on swaps and interest rate caps and floors) in order to hedge various risks, such as interest rate and currency risk. The Fund may use derivative instruments for other investment purposes, such as replicating permitted investments, as long as such investments do not have the effect of leveraging portfolio risks. The Fund is not required to use hedging and may choose not to do so.

The Fund may sell a security if the security is overvalued on a relative basis compared to other securities available in the market, if the fundamentals of the company are deteriorating, or for duration management purposes. The Fund may also sell a security to meet redemptions.

The Fund utilizes an active trading approach, which may result in portfolio turnover greater than 100%.

Principal Investment Risks

You could lose money by investing in the Fund. The following is a summary description of the principal risks of investing in the Fund:

· Derivatives Risk. Derivative investments involve counterparty risk (the risk that the counterparty of the derivative transaction will be unable to honor its financial obligation to the Fund), basis risk (the risk that the derivative instrument will not fully offset the underlying positions), and liquidity risk (the risk that the Fund cannot sell the derivative instrument because of an illiquid secondary market). In addition, the portfolio manager may incorrectly forecast the values of securities, currencies or interest rates or other economic factors in using derivatives for the Fund.

·  Foreign Banks and Securities Depositories Risk. Some foreign banks and securities depositories in which the Fund generally holds its foreign securities may be recently organized or new to the foreign custody business. In addition, there may be limited or no regulatory oversight over their operations. Also, the laws of certain countries may put limits on the Fund’s ability to recover its assets if a foreign bank, depository or issuer of a security, or any of their agents, goes bankrupt.

· General Fixed-Income Securities Risk. The market prices of bonds, including those issued by the U.S. government, go up as interest rates fall, and go down as interest rates rise. As a result, the net asset value of the Fund will fluctuate with conditions in the bond markets. In the case of corporate bonds and commercial paper, values may fluctuate as perceptions of credit quality change. In addition, corporate bonds may be downgraded or default. During periods of declining interest rates or for other reasons, bonds may be “called”, or redeemed, by the bond issuer prior to the bond’s maturity date, resulting in the Fund receiving payment earlier than expected. This may reduce the Fund’s income if the proceeds are reinvested at a lower interest rate.

· General Foreign Securities Risk. Investments in foreign securities may be affected unfavorably by changes in currency rates or exchange control regulations, or political or social instability in the particular foreign country or region. The Fund is not required to hedge against changes in foreign currency exchange rates.

· Government Securities Risk. Economic, business, or political developments may affect the ability of government-sponsored guarantors to repay principal and to make interest payments on the securities in which the Fund invests. In addition, certain of these securities, including those issued or guaranteed by FNMA and FHLMC, are not backed by the full faith and credit of the U.S. government.

· Lower-Quality Bonds Risk. Bonds with lower credit ratings are more speculative and likely to default than higher-quality bonds. Lower-rated bonds also tend to fluctuate more widely in value.

· Mortgage-Backed Securities Risk. Mortgage-backed securities represent interests in “pools” of mortgages and are subject to certain additional risks. When interest rates rise, certain obligations will be paid off by the obligor more slowly than anticipated causing the value of these securities to fall. This is known as extension risk. In addition, adjustable and fixed rate mortgage-related securities are subject to prepayment risk. When interest rates decline, borrowers may pay off their mortgages sooner than expected. This can reduce the returns of the Fund because the Fund may have to reinvest that money at the lower prevailing interest rates. These securities also are subject to risk of default on the underlying mortgage, particularly during periods of economic downturn.

· Municipal Securities Risk. Municipal securities can be significantly affected by political changes as well as uncertainties in the municipal market related to taxation, legislative changes, or the rights of municipal security holders.

· Portfolio Turnover Risk. An active trading approach increases the Fund’s costs and may reduce the Fund’s performance. It may also increase the amount of capital gains tax that you have to pay on the Fund’s returns.

Performance

The following bar chart and table provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for 1 year and since inception compare with those of a broad measure of market performance. The bar chart shows the Fund’s performance for Class A shares for each calendar year since inception. Sales charges are not reflected in the bar chart. If sales charges were reflected, returns would be less than those shown. However, the table includes, for share classes with a sales charge, the effect of the maximum sales charge, including any contingent deferred sales charge that would apply to a redemption at the end of the period. How the Fund performed in the past (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated information on the Fund’s results can be obtained by visiting www.sentinelinvestments.com.

After-tax returns are calculated using the historical highest applicable individual federal marginal income tax rates in effect during the relevant period and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. After-tax returns are shown only for Class A shares and after-tax returns for other classes of shares will vary.

[1] You pay a deferred sales charge of 0.50% on certain redemptions of Class A shares made within twelve months of purchase if you bought them without an initial sales charge as part of an investment of $500,000 more.

[1] 12b-1 fees have been restated from fiscal year amounts to reflect the maximum fee payable under the applicable distribution plan for such share class. 12b-1 fees are not assessed with respect to shares owned by NLV Financial Corporation or an affiliate ("NLVFin"), which may result in an overall 12b-1 fee charged to all shareholders of less than the maximum for so long as the NLVFin investment is maintained.

[2] The Fund's investment advisor has contractually agreed, effective March 30, 2013, to waive fees and/or reimburse certain expenses in order to limit Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement for Class A shares, on an annualized basis, to 0.89% of average daily net assets attributable to Class A shares through March 31, 2014. This agreement may be terminated upon 90 days' notice by a majority of the non-interested directors of the Fund.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund normally invests at least 80% of its net assets in equity securities. The Fund invests mainly in common stocks of established companies located in or that conduct their business mainly in one or more foreign countries, which may include emerging markets. The Fund will normally be invested in ten or more foreign countries and may invest up to 40% of its assets in any one country if Sentinel feels that economic and business conditions make it appropriate to do so. The Fund focuses its investments on developed foreign countries, but may invest up to 25% of its total assets in emerging markets. It normally will have substantial investments in European countries. Normally, at least 75% of the Fund’s total assets are invested in securities of non-U.S. issuers selected by Sentinel mainly for their long-term capital growth prospects. The remaining 25% may be invested in companies organized in the United States that have at least 50% of their assets and/or revenues outside the United States. The Fund also expects to purchase American Depositary Receipts (ADRs) and Global Depositary Receipts in bearer form, which are designed for use in non-U.S. securities markets.

The Fund also may invest in convertible or debt securities rated Baa or higher by Moody’s Investors Service, Inc. or BBB or higher by Standard & Poor’s.

Sentinel applies a multi-dimensional strategy for portfolio construction — trend identification, stock selection and risk management. Trends are identified that affect global and regional economic and financial environments, setting a framework for stock selection; stocks are then analyzed and ranked based on the following five factors: valuation, growth, management, business quality and balance sheet strength. Risk is managed through portfolio diversification. Typically, the Fund has no more than double the weight of the MSCI EAFE index or less than half the weight of the index in the largest countries in the index.

The Fund generally may sell a security when there is a deterioration of one or more of the five factors described above or when the portfolio manager identifies a more favorable investment opportunity. The Fund may also sell a security to meet redemptions.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

You could lose money by investing in the Fund. The following is a summary description of the principal risks of investing in the Fund:

· Emerging Markets Risk. The risks of foreign investments are usually much greater for the emerging markets. Investments in emerging markets may be considered speculative. Emerging markets are riskier because they develop unevenly and may never fully develop. In addition, many emerging securities markets have lower trading volumes and less liquidity than developed markets.

· Foreign Banks and Securities Depositories Risk. Some foreign banks and securities depositories in which the Fund generally holds its foreign securities may be recently organized or new to the foreign custody business. In addition, there may be limited or no regulatory oversight over their operations. Also, the laws of certain countries may put limits on the Fund’s ability to recover its assets if a foreign bank, depository or issuer of a security, or any of their agents, goes bankrupt.

· General Foreign Securities Risk. Investments in foreign securities may be affected unfavorably by changes in currency rates or exchange control regulations, or political and/or social instability in a particular foreign country or region.

· Investment Style Risk. The Fund’s growth style of investing may be out of favor at any particular time. The stocks of growth companies may be more sensitive to investor perceptions about company earnings than other stocks and may be more volatile than the market in general.

· Sector Risk. Investments in a particular sector may trail returns from other economic sectors.

· Stock Market and Selection Risk. The stock market may go down in value, and may go down sharply and unpredictably. The stocks selected by the portfolio manager may underperform the stock market or other funds with similar investment objectives and investment strategies.

Strategy [Heading]

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund normally invests at least 65% of its net assets in stocks of well-established U.S. companies, typically those above $5 billion in market capitalization. The Fund may invest without limitation in foreign securities.

Sentinel’s investment philosophy centers on building a diverse portfolio consisting largely of securities of high quality companies with a positive multi-year outlook offered at attractive valuation levels, based on a number of metrics, including value relative to its history, peers and/or the market over time. The Fund may also invest in stocks with the potential to provide current income, growth of income and relatively low risk as compared to the stock market as a whole when consistent with the Fund’s investment objective.

Up to 25% of the Fund’s assets may be invested in securities within a single industry. Although the Fund may invest in any economic sector, at times it may emphasize one or more particular sectors. Sentinel has a preference for companies that earn above-average rates of return on capital and that generate free cash flow. Additionally, earnings revision trends are important.

The Fund may sell a security if the fundamentals of the company are deteriorating or the original investment premise is no longer valid, the stock is trading meaningfully higher than what the portfolio manager believes is a fair valuation, to manage the size of the holding or the sector weighting and/or to take advantage of a more attractive investment opportunity, and to meet redemptions. A security will also be sold if it is determined that it no longer meets the environmental, social and/or corporate governance performance criteria.

Sustainable and Responsible Investing. The Fund employs a process of environmental, social and corporate governance (“ESG”) screening that is overseen by Sentinel’s in-house sustainable research department. While no investment is ever made solely based on the qualitative criteria alone, the Fund believes sustainable screening provides a unique and more comprehensive view of the companies it considers for investment. Generally, companies are eliminated from investment consideration if they produce tobacco or tobacco products or alcoholic beverages; generate nuclear power or supply nuclear facilities with industry specific components, as a primary line of business; have material interests in the manufacture of weapons or weapons-specific components; are involved in gambling as a main line of business; and/or lack diversity at the level of the board of directors/senior management. The Fund favors companies that publish and enforce codes of conduct and vendor standards; promote equal opportunity, diversity and good employee relations; are sensitive to community concerns; seek alternatives to animal testing when not required by law; and/or have minimal impact on the environment and engage in proactive environmental initiatives.

Sentinel may, in its discretion, choose to apply additional screens, modify the application of the screens listed above or vary the application of the screens listed above to the Funds’ investments at any time without shareholder approval.

For additional information on the environmental, social and governance screening process used by the Fund, please see “Additional Information About Each Fund — Investment Objectives and Strategies — Sentinel Sustainable Core Opportunities Fund — Principal Investment Strategies” at page 86 of the Prospectus.

Risk [Heading]

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

· Foreign Banks and Securities Depositories Risk. Some foreign banks and securities depositories in which the Fund generally holds its foreign securities may be recently organized or new to the foreign custody business. In addition, there may be limited or no regulatory oversight over their operations. Also, the laws of certain countries may put limits on the Fund’s ability to recover its assets if a foreign bank, depository or issuer of a security, or any of their agents, goes bankrupt.

· General Foreign Securities Risk. Investments in foreign securities may be affected unfavorably by changes in currency rates or exchange control regulations, or political and/or social instability in a particular foreign country or region.

· Investment Style Risk. The Fund uses a “blend” strategy to invest in both growth and value stocks, and/or in stocks with characteristics of both. This strategy may be out of favor at any particular time. The prices of growth stocks may fall dramatically if the company fails to meet earnings or revenue projections. The prices of value stocks may lag the stock market for long periods of time if the market fails to recognize the company’s intrinsic worth.

· Sector Risk. Investments in a particular sector may trail returns from other economic sectors.

· Stock Market and Selection Risk. The stock market may go down in value, and may go down sharply and unpredictably. The stocks selected by the portfolio manager may underperform the stock market or other funds with similar investment objectives and investment strategies.

· Sustainable/Responsible Investing Risk. The Fund’s environmental, social and corporate governance criteria may cause the Fund to forgo opportunities to buy certain securities, and/or forgo opportunities to gain exposure to certain industries, sectors, regions and countries. In addition, the Fund may be required to sell a security when it might otherwise be disadvantageous for it to do so.

The following bar chart and table provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for 1, 5 and 10 years compare with those of broad measures of market performance. The bar chart shows changes in the Fund’s performance for Class A shares for each calendar year over a ten-year period. Sales charges are not reflected in the bar chart. If sales charges were reflected, returns would be less than those shown. However, the table includes, for share classes with a sales charge, the effect of the maximum sales charge. How the Fund performed in the past (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated information on the Fund’s results can be obtained by visiting www.sentinelinvestments.com.

The Sentinel Sustainable Core Opportunities Fund, which began operations on April 4, 2008, is a successor to the Citizens Value Fund, which was a successor to the Meyers Pride Value Fund, which began operations on June 13, 1996. Performance for the Class A shares of the Fund from September 24, 2001 to April 4, 2008 is based on the performance of the Standard shares of the predecessor Citizens Value Fund, which was offered without a sales charge and reflects the current maximum sales charge. Performance of the Class A shares from their inception on April 4, 2008 to June 29, 2012, has not been adjusted to reflect the lower maximum 12b-1 fee in effect prior to April 4, 2008 or the decrease in the maximum 12b-1 fee, effective June 30, 2012, from 0.30% to 0.25%. If it had, those returns would be higher. Performance of the Class I shares from March 31, 2006 to April 4, 2008 (the inception date for the Class I shares) is based on the performance of the Institutional shares of the Citizens Value Fund, which had different expenses but substantially similar investment risks and from September 24, 2001 to March 31, 2006 is based on the performance of the Standard shares of the Citizens Value Fund.

SENTINEL GEORGIA MUNICIPAL BOND FUND | SENTINEL GEORGIA MUNICIPAL BOND FUND

SENTINEL GEORGIA MUNICIPAL BOND FUND

Investment Objective

The Fund seeks current income exempt from both federal and Georgia state income taxes, consistent with preservation of capital.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund.

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees	SENTINEL GEORGIA MUNICIPAL BOND FUND CLASS I
Maximum Sales Charge (Load) Imposed on Purchases (as a percentage of offering price)	none
Maximum Deferred Sales Charge (Load)(as a percentage of purchase price or redemption proceeds, whichever is less)	none
Redemption Fees (as a percentage of amounts redeemed or exchanged within 30 days)	none

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	SENTINEL GEORGIA MUNICIPAL BOND FUND CLASS I
Management Fee	0.45%
Distribution and/or Service (12b-1) Fees	none
Other Expenses	0.23%
Total Annual Fund Operating Expenses	0.68%

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 (actual Fund minimums may be higher) in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same.

Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Expense Example (USD $)	1 Year	3 Years	5 Years	10 Years
SENTINEL GEORGIA MUNICIPAL BOND FUND CLASS I	69	218	379	847

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 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 5% of the average value of its portfolio.

Principal Investment Strategies

The Fund normally invests at least 80% of its total assets in municipal securities that generate income that, in the opinion of counsel to the issuer of the security, is exempt from federal and Georgia state income taxes.

The Fund may invest in municipal obligations whose interest is a tax-preference item for purposes of the federal alternative minimum tax (“AMT”). If you are subject to the AMT, a portion of the Fund’s distributions to you may not be exempt from federal income tax.

The Fund’s investment sub-adviser will purchase investment-grade municipal securities in an attempt to maintain an average weighted portfolio maturity of five to fifteen years, as determined by market conditions. As a core, general obligation, revenue, school, housing, hospital development and insured municipal bonds are represented. GLOBALT considers the relative yield, maturity and availability of various types of municipal bonds and the general economic outlook in determining how much to invest in a specific type of municipal bond in the Fund’s portfolio. Duration adjustments are made relative to the Barclays 10-Year Municipal Bond Index.

The Fund is “non-diversified,” which means that the Fund may concentrate its assets in a smaller number of issuers than a diversified fund, thus increasing the importance of each holding.

Principal Investment Risks

You could lose money by investing in the Fund. The following is a summary description of the principal risks of investing in the Fund:

· General Fixed-Income Securities Risk. The market prices of bonds, including those issued by the U.S. government, go up as interest rates fall, and go down as interest rates rise. As a result, the net asset value of the shares of Funds holding bonds will fluctuate with conditions in the bond markets.

· Municipal Lease Risk. Municipal leases contain non-appropriation clauses under which the municipality may elect annually not to appropriate funds for future lease payments. As a result, the Fund may not receive payments from a lease obligation as originally anticipated.

· Non-Diversified Risk. Because the Fund holds fewer securities than a diversified portfolio and may take larger positions in individual securities, the Fund may be more affected by the performance of any particular security.

· Related Projects Risk. The Fund invests in issuers that finance similar types of municipal projects and obligors whose principal business activities are in the same types of municipal projects. As a result, the value of the Fund’s shares may be adversely affected by the effects of economic, political, tax law or business developments related to the municipal projects.

· State-Specific Risk. The Fund is more susceptible to factors adversely affecting Georgia governmental entities than a municipal bond fund that is diversified nationally. Changes in the economic condition and governmental policies of the State of Georgia may cause the value of the Fund’s shares to fall.

· Taxability Risk. While the Fund seeks to invest in municipal bonds whose interest payments will be excludable from gross income for federal income tax purposes, a municipal bond may be reclassified as taxable by the Internal Revenue Service. In addition, future legislative, administrative or court actions may cause interest on municipal bonds to be subject to federal income taxation, subjecting an investor to increased tax liability and/or adversely impacting the value of the security.

· U.S. Territory-Specific Risk. The Fund is susceptible to factors adversely affecting certain U.S. territories that issue securities that may be exempt from federal, and in certain circumstances, state and local taxes.

Performance

The following bar chart and table provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for 1, 5 and 10 years compare with those of a broad measure of market performance. The bar chart shows changes in the Fund’s performance for Class I shares for each calendar year over a ten-year period. How the Fund performed in the past (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated information on the Fund’s results can be obtained by visiting www.sentinelinvestments.com.

The Sentinel Georgia Municipal Bond Fund began operations on May 4, 2007. The Fund is a successor to the Synovus Georgia Municipal Bond Fund, which was a successor to a similarly managed collective investment fund, which commenced operations in 1992. Performance for the Class I shares from October 12, 2001 to May 4, 2007 is based on the Synovus Georgia Municipal Bond Fund’s Institutional Class shares.

Inception: 1992 (the inception of the Fund’s predecessor)

Annual Total Return for Class I Shares (%) as of December 31

During the ten-year period shown in the above bar chart, the highest return for a quarter was 4.24% (quarter ended December 31, 2008) and the lowest return for a quarter was -3.24% (quarter ended December 31, 2010).

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same.

Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Expense Example Sentinel Conservative Strategies Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Class A	606	829	1,071	1,762
Class C	284	569	980	2,127
Class I	102	318	552	1,225

You would pay the following expenses if you did not redeem your shares:

Expense Example No Redemption (USD $)	1 Year	3 Years	5 Years	10 Years
Sentinel Conservative Strategies Fund Class C	184	569	980	2,127

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 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 315% of the average value of its portfolio.

Principal Investment Strategies

The Fund normally divides its assets among several broad asset classes. Sentinel has broad discretion in allocating assets among the classes. The classes are:

1. INVESTMENT-GRADE BONDS. The Fund may invest up to 70% of its total assets in U.S. and non-U.S. sovereign government debt, and U.S. and non- U.S. dollar denominated investment-grade corporate bonds, and may include dollar roll transactions.

2. BELOW INVESTMENT-GRADE BONDS. The Fund may invest up to 70% of its total assets in U.S. dollar and non-U.S. dollar -denominated bonds rated below investment-grade (e.g., rated below BBB by Standard and Poor’s or below Baa by Moody’s) or which are unrated. These bonds are sometimes called “junk bonds”. The Fund expects that normally, no more than 45% of its total assets will be invested in this asset class, but Sentinel may increase the total assets invested in this asset class up to 70% for short periods of time when Sentinel believes that this asset class offers attractive yields and good value relative to other asset classes.

3. EQUITY AND EQUITY-RELATED SECURITIES. The Fund may invest up to 100% of its total assets in these securities, including common stocks, preferred stocks, and debt securities that are convertible into equity securities. In choosing investments within this category, investments which offer relatively high dividend or interest yields will be emphasized, but there will also be some emphasis on the potential for capital appreciation. The Fund may invest up to 70% of its total assets in foreign securities, including emerging markets.

The Fund may attempt to hedge various risks, such as interest rate and currency risk, using derivative instruments (e.g., exchange-traded futures and options, and other derivatives such as swaps, options on swaps, and caps and floors), and may use derivative instruments for other investment purposes such as replicating permitted investments, as long as such investments do not have the effect of leveraging portfolio risks. The Fund is not required to use hedging and may choose not to do so.

When making allocation decisions for the portfolio, the investment team works collaboratively to determine the appropriate allocation weightings based on their consideration of top-down macro-economic data relating to the U.S. and global markets, as well as bottom-up fundamental analysis to determine which asset classes appear to offer better relative value.

The Fund utilizes an active trading approach, which may result in portfolio turnover greater than 100%.

Principal Investment Risks

You could lose money by investing in the Fund. The following is a summary description of the principal risks of investing in the Fund:

· Asset Allocation Risk The Fund’s allocations to the various asset classes and market sectors could cause the Fund to underperform other funds with a similar investment objective.

· Derivatives Risk. Derivative investments involve counterparty risk (the risk that the counterparty of the derivative transaction will be unable to honor its financial obligation to the Fund), basis risk (the risk that the derivative instrument will not fully offset the underlying positions), and liquidity risk (the risk that the Fund cannot sell the derivative instrument because of an illiquid secondary market). In addition, the portfolio manager may incorrectly forecast the values of securities, currencies or interest rates or other economic factors in using derivatives for the Fund.

· Emerging Markets Risk. The risks of foreign investments are usually much greater for the emerging markets. Investments in emerging markets may be considered speculative. Emerging markets are riskier because they develop unevenly and may never fully develop. In addition, many emerging securities markets have lower trading volumes and less liquidity than developed markets.

· Foreign Banks and Securities Depositories Risk. Some foreign banks and securities depositories in which the Fund generally holds its foreign securities may be recently organized or new to the foreign custody business. In addition, there may be limited or no regulatory oversight over their operations. Also, the laws of certain countries may put limits on the Fund’s ability to recover its assets if a foreign bank, depository or issuer of a security, or any of their agents, goes bankrupt.

· General Fixed-Income Securities Risk. The market prices of bonds, including those issued by the U.S. government, go up as interest rates fall, and go down as interest rates rise. As a result, the net asset value of the Fund will fluctuate with conditions in the bond markets. In the case of corporate bonds and commercial paper, values may fluctuate as perceptions of credit quality change. In addition, corporate bonds may be downgraded or default. During periods of declining interest rates or for other reasons, bonds may be “called”, or redeemed, by the bond issuer prior to the bond’s maturity date, resulting in the Fund receiving payment earlier than expected. This may reduce the Fund’s income if the proceeds are reinvested at a lower interest rate.

· General Foreign Securities Risk. Investments in foreign securities may be affected unfavorably by changes in currency rates or exchange control regulations, or political or social instability in the particular foreign country or region. The Fund is not required to hedge against changes in foreign currency exchange rates.

· Government Securities Risk. Economic, business, or political developments may affect the ability of government-sponsored guarantors to repay principal and to make interest payments on the securities in which the Fund invests. In addition, certain of these securities, including those issued or guaranteed by FNMA and FHLMC, are not backed by the full faith and credit of the U.S. government.

· Investment Style Risk. The Fund invests in “growth” and “value” stocks, and in stocks with characteristics of both. These different types of stocks may be out of favor at any particular time. The stocks of “growth” companies may be more sensitive to investor perceptions about company earnings and may be more volatile than the market in general. The stocks of “value” companies may be undervalued by the market for long periods of time.

· Lower-Quality Bonds Risk. Bonds with lower credit ratings are more speculative and likely to default than higher-quality bonds. Lower-rated bonds also tend to fluctuate more widely in value.

· Mortgage-Backed Securities Risk. Mortgage-backed securities represent interests in “pools” of mortgages and are subject to certain additional risks. When interest rates rise, certain obligations will be paid off by the obligor more slowly than anticipated causing the value of these securities to fall. This is known as extension risk. In addition, adjustable and fixed rate mortgage-related securities are subject to prepayment risk. When interest rates decline, borrowers may pay off their mortgages sooner than expected. This can reduce the returns of the Fund because the Fund may have to reinvest that money at the lower prevailing interest rates. These securities also are subject to risk of default on the underlying mortgage, particularly during periods of economic downturn.

· Portfolio Turnover Risk. An active trading approach increases the Fund’s costs and may reduce the Fund’s performance. It may also increase the amount of capital gains tax that you have to pay on the Fund’s returns.

· Sector Risk. Investments in a particular sector may trail returns from other economic sectors.

· Stock Market and Selection Risk. The stock market may go down in value, and may go down sharply and unpredictably. The stocks selected by the portfolio manager may underperform the stock market or other funds with similar investment objectives and investment strategies.

Performance

The following bar chart and table provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for 1 and 5 years and since inception compare with those of broad measures of market performance. The bar chart shows changes in the Fund’s performance for Class A shares for each calendar year since inception. Sales charges are not reflected in the bar chart. If sales charges were reflected, returns would be less than those shown. However, the table includes, for share classes with a sales charge, the effect of the maximum sales charge, including any contingent deferred sales charge that would apply to a redemption at the end of the period. How the Fund performed in the past is not necessarily an indication of how the Fund will perform in the future. Updated information on the Fund’s results can be obtained by visiting www.sentinelinvestments.com.

Performance of the Class A shares prior to June 30, 2012, has not been adjusted to reflect the decrease in the maximum 12b-1 fee from 0.30% to 0.25%. If it had, those returns would be higher. Performance of the Class I shares prior to December 17, 2010 (the inception date for the Class I shares) is based on the Fund’s Class A share performance, restated to reflect that Class I shares are offered without a sales charge. Effective December 17, 2010, the Fund changed its investment strategies. The performance information provided below for periods prior to December 17, 2010 relates to the Fund’s investment strategies that were in effect prior to December 17, 2010.

Inception: 2003

Annual Total Return for Class A Shares (%) as of December 31

During the period(s) shown in the above bar chart, the highest return for a quarter was 7.66% (quarter ended September 30, 2009) and the lowest return for a quarter was -10.97% (quarter ended December 31, 2008).

After-tax returns are calculated using the historical highest applicable individual federal marginal income tax rates in effect during the relevant period and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. After-tax returns are shown only for Class A shares and after-tax returns for other classes of shares will vary.

[1] You pay a deferred sales charge of 1% on certain redemptions of Class A shares made within twelve months of purchase if you bought them without an initial sales charge as part of an investment of $1,000,000 or more.

[1] 12b-1 fees have been restated to reflect a reduction in the maximum fee from 0.30% to 0.25% effective June 30, 2012. Because of this restatement, the Total Annual Fund Operating Expenses do not correlate to the ratio of expenses to average net assets shown in the Fund's most recent annual report.

[1] The Barclays US Aggregate Bond Index measures the U.S. investment grade fixed-rate bond market, with index components for government and corporate securities, mortgage pass-through securities, and asset-backed securities. The Fund compares its performance to this index because the Fund's investment strategy includes investments in the asset classes that comprise the index.

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund normally invests at least 80% of its net assets in small-capitalization companies. For this purpose, small capitalization companies are companies that have, at the time of purchase, market capitalizations of less than $4 billion. The Fund seeks to invest primarily in common stocks of small companies that Sentinel believes are high quality, have superior business models, solid management teams, sustainable growth potential and are attractively valued. The Fund may invest without limitation in foreign securities, although only where the securities are trading in the U.S. or Canada and only where trading is denominated in U.S. or Canadian dollars.

Up to 25% of the Fund’s assets may be invested in securities within a single industry. For portfolio construction purposes, the Fund uses the Standard & Poor’s SmallCap 600 Index as a sector-weighting guide, generally using a plus or minus 25% weighting. The Fund attempts to be well-balanced across major economic sectors. Although the Fund may invest in any economic sector, at times it may emphasize one or more particular sectors.

The Fund would typically sell a security if the portfolio managers believe it is overvalued, if the original investment premise is no longer true, if the market cap exceeds a specified threshold, if the holding size exceeds the portfolio managers’ company or sector weighting guidelines and/or to take advantage of a more attractive investment opportunity. The Fund may also sell a partial position in a security in order to manage the size of the position. A security may also be sold to meet redemptions.

Principal Investment Risks

Risk Narrative [Text Block]

You could lose money by investing in the Fund. The following is a summary description of the principal risks of investing in the Fund:

· General Foreign Securities Risk. Investments in foreign securities may be affected unfavorably by changes in currency rates or exchange control regulations, or political and/or social instability in a particular foreign country or region.

· Investment Style Risk. The Fund’s growth style of investing may be out of favor at any particular time. The stocks of growth companies may be more sensitive to investor perceptions about company earnings than other stocks and may be more volatile than the market in general.

· Restricted and Illiquid Securities Risk. The Fund will not be able to readily resell illiquid securities and resale of some of these securities may be restricted by law or contractual provisions. The inability to sell these securities at the most opportune time may negatively affect the Fund’s net asset value.

· Sector Risk. Investments in a particular sector may trail returns from other economic sectors.

· Stock Market and Selection Risk. The stock market may go down in value, and may go down sharply and unpredictably. The stocks selected by the portfolio manager may underperform the stock market or other funds with similar investment objectives and investment strategies.

· Stocks of Smaller Companies Risk. The stocks of small- and/or mid-capitalization companies in which the Fund invests typically involve more risk than the stocks of larger companies. These smaller companies may have more limited financial resources and product lines, and may have less seasoned managers. In addition, these stocks may trade less frequently and in lower share volumes, making them subject to wider price fluctuations.

The Fund seeks long-term capital appreciation.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $25,000 in shares of the Sentinel Funds that include Class A shares. More information about these and other discounts is available from your financial professional and in the section entitled “Share Classes” on page 98 of the Fund’s prospectus and “How to Purchase Shares and Reduce Sales Charges” on page 52 of the Fund’s statement of additional information.

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same.

Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Expense Example Sentinel Growth Leaders Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Class A	651	968	1,307	2,264
Class C	447	1,056	1,788	3,721
CLASS I	133	415	718	1,579

You would pay the following expenses if you did not redeem your shares:

Expense Example No Redemption (USD $)	1 Year	3 Years	5 Years	10 Years
Sentinel Growth Leaders Fund Class C	347	1,056	1,788	3,721

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 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% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a non-diversified fund that invests in stocks of companies that Sentinel believes have attractive business models, solid management and growth potential.

As a non-diversified fund with fewer securities than a diversified portfolio, there is greater risk in that each holding has a greater impact on performance, either positively or negatively.

Sentinel looks to invest in high quality companies that are expected to grow as a result of superior investments, strong capital stewardship and unique positioning in attractive business segments. When selecting investments, focus is on company-specific variables, such as competitive industry dynamics, market leadership, proprietary products and services, and management expertise, as well as on financial characteristics, such as returns on sales and equity, debt/equity ratios and earnings and cash flow growth. In addition, Sentinel looks for companies that it perceives to be attractively valued relative to their future growth prospects, as well as to that of the market as a whole.

The Fund typically invests in 30-40 common stocks from any economic sector, and at times, it may emphasize one or more particular sectors. The Fund may invest up to 25% of its net assets in a single industry. While the Fund typically focuses on securities of U.S. companies, it may without limitation, invest in securities of foreign issuers.

Sentinel expects to sell Fund holdings when the fundamentals of a company are perceived to be deteriorating, the valuation of the underlying company relative to its future growth rate appears to have become excessive, or when more attractive alternative investments surface. Sentinel may also sell Fund holdings to meet redemptions.

Principal Investment Risks

You could lose money by investing in the Fund. The following is a summary description of the principal risks of investing in the Fund:

· Foreign Banks and Securities Depositories Risk. Some foreign banks and securities depositories in which the Fund generally holds its foreign securities may be recently organized or new to the foreign custody business. In addition, there may be limited or no regulatory oversight over their operations. Also, the laws of certain countries may put limits on the Fund’s ability to recover its assets if a foreign bank, depository or issuer of a security, or any of their agents, goes bankrupt.

· General Foreign Securities Risk. Investments in foreign securities may be affected unfavorably by changes in currency rates or exchange control regulations, or political and/or social instability in a particular foreign country or region.

· Investment Style Risk. The Fund’s growth style of investing may be out of favor at any particular time. The stocks of growth companies may be more sensitive to investor perceptions about company earnings than other stocks and may be more volatile than the market in general.

· Non-Diversified Risk. The Fund is a non-diversified fund, meaning that it may hold fewer securities than a diversified portfolio and may take larger positions in individual securities. As a result, the Fund may be more affected by the performance of a particular security than a fund investing in a broader range of securities.

· Sector Risk. Investments in a particular sector may trail returns from other economic sectors.

· Stock Market and Selection Risk. The stock market may go down in value, and may go down sharply and unpredictably. The stocks selected by the portfolio manager may underperform the stock market or other funds with similar investment objectives and investment strategies.

Performance

The following bar chart and table provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for 1, 5 and 10 years compare with those of broad measures of market performance. The bar chart shows changes in the Fund’s performance for Class A shares for each calendar year over a ten-year period. Sales charges are not reflected in the bar chart. If sales charges were reflected, returns would be less than those shown. However, the table includes, for share classes with a sales charge, the effect of the maximum sales charge, including any contingent deferred sales charge that would apply to a redemption at the end of the period. How the Fund performed in the past (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated information on the Fund’s results can be obtained by visiting www.sentinelinvestments.com.

The Sentinel Growth Leaders Fund began operations on March 17, 2006. Performance for the Fund prior to March 17, 2006 is based on the performance of its predecessor, the Bramwell Focus Fund, which was offered without a sales charge. Performance of Class A shares reflects the current maximum sales charge. Performance of the Class A shares from their inception on March 17, 2006 to June 29, 2012, has not been adjusted to reflect the lower maximum 12b-1 fee in effect prior to March 17, 2006 or the decrease in the maximum 12b-1 fee, effective June 30, 2012, from 0.30% to 0.25%. If it had, those returns would be higher. Performance of Class C shares prior to March 17, 2006 (the inception date for the Class C shares) has been adjusted for the higher estimated expenses of those shares. Performance of the Class I shares from March 17, 2006 to August 27, 2007 (the inception date for the Class I shares) is based on the Fund’s Class A shares, restated to reflect that Class I shares are offered without a sales charge.

Inception: 1999 (the inception of the Fund’s predecessor)

Annual Total Return for Class A Shares (%) as of December 31

During the ten-year period shown in the above bar chart, the highest return for a quarter was 12.70% (quarter ended March 31, 2012) and the lowest return for a quarter was -19.38% (quarter ended September 30, 2008).

Standard & Poor’s 500 Index (Reflects no deduction for fees, expenses or taxes)	[2]	16.00%	1.66%	7.10%

After-tax returns are calculated using the historical highest applicable individual federal marginal income tax rates in effect during the relevant period and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. After-tax returns are shown only for Class A shares and after-tax returns for other classes of shares will vary.

[1] You pay a deferred sales charge of 1% on certain redemptions of Class A shares made within twelve months of purchase if you bought them without an initial sales charge as part of an investment of $1,000,000 or more.

[1] 12b-1 fees have been restated to reflect a reduction in the maximum fee from 0.30% to 0.25% effective June 30, 2012. Because of this restatement, the Total Annual Fund Operating Expenses do not correlate to the ratio of expenses to average net assets shown in the Fund's most recent annual report.

[2] 12b-1 fees have been restated from fiscal year amounts to reflect the maximum fee payable under the applicable distribution plan for such share class. 12b-1 fees are not assessed with respect to shares owned by NLV Financial Corporation or an affiliate ("NLVFin"), which may result in an overall distribution fee charged to all shareholders of less than the maximum for so long as the NLVFin investment is maintained.

[3] The Fund's investment adviser has contractually agreed, effective March 30, 2013, to waive fees and/or reimburse certain expenses in order to limit Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement for Class A shares, on an annualized basis, to 1.45% of average daily net assets attributable to Class A shares through March 31, 2014. This agreement may be terminated upon 90 days' notice by a majority of the non-interested directors of the Fund.

[1] Return after taxes on distributions and sale of fund shares may be higher than return before taxes and/or return after taxes on distributions when a net capital loss occurs upon the redemption of fund shares.

[2] The Standard & Poor's 500 Index consists of 500 widely held U.S. equity securities chosen for market size, liquidity, and industry group representation. The Fund compares its performance to this index because Fund management believes it is an appropriate alternative measure of the Fund's investment strategy.

Expense Example No Redemption (USD $)	1 Year	3 Years	5 Years	10 Years
Sentinel Government Securities Fund Class C	162	502	866	1,889

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 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 581% of the average value of its portfolio.

Principal Investment Strategies

The Fund normally invests at least 80% of its net assets in U.S. government securities and related derivatives. Related derivatives include exchange-traded futures on U.S. Treasury notes and bonds, and options on these futures, and other derivatives intended to hedge interest rate risk, such as swaps, options on swaps, and interest rate caps and floors. The Fund invests mainly in U.S. government bonds. These bonds include direct obligations of the U.S. Treasury, obligations guaranteed by the U.S. government, and obligations of U.S. government agencies and instrumentalities. The Fund is not required, however, to invest set amounts in any of the various types of U.S. government securities. Sentinel will choose the types of U.S. government securities that it believes will provide capital preservation and the best return with the least risk in light of its analysis of current market conditions and its outlook for interest rates and the economy.

The Fund invests substantially in U.S. government mortgage-backed securities issued and/or guaranteed by the Federal National Mortgage Association (“FNMA” or “Fannie Mae”), the Federal Home Loan Mortgage Corporation (“FHLMC” or “Freddie Mac”) and the Government National Mortgage Association (“GNMA” or “Ginnie Mae”).

The Fund may attempt to hedge various risks, such as interest rate risk, using derivative instruments (e.g., futures and options on futures, swaps, options on swaps, and caps and floors), and may use derivative instruments for other investment purposes such as replicating permitted investments, as long as such investments do not have the effect of leveraging portfolio risks. The Fund is not required to use hedging and may choose not to do so.

The Fund may sell a security if the security is overvalued on a relative basis compared to other securities available in the market or for duration management purposes. The Fund may also sell a security to meet redemptions.

The Fund utilizes an active trading approach, which may result in portfolio turnover greater than 100%.

Principal Investment Risks

You could lose money by investing in the Fund. The following is a summary description of the principal risks of investing in the Fund:

· Derivatives Risk. Derivative investments involve counterparty risk (the risk that the counterparty of the derivative transaction will be unable to honor its financial obligation to the Fund), basis risk (the risk that the derivative instrument will not fully offset the underlying positions), and liquidity risk (the risk that the Fund cannot sell the derivative instrument because of an illiquid secondary market). In addition, the portfolio manager may incorrectly forecast the values of securities, currencies or interest rates or other economic factors in using derivatives for the Fund.

· General Fixed-Income Securities Risk. The market prices of bonds, including those issued by the U.S. government, go up as interest rates fall, and go down as interest rates rise. As a result, the net asset value of the shares of Funds holding bonds will fluctuate with conditions in the bond markets.

· Government Securities Risk. Economic, business, or political developments may affect the ability of government-sponsored guarantors to repay principal and to make interest payments on the securities in which the Fund invests. In addition, certain of these securities, including those issued or guaranteed by FNMA and FHLMC, are not backed by the full faith and credit of the U.S. government.

·  Mortgage-Backed Securities Risk. Mortgage-backed securities represent interests in “pools” of mortgages and are subject to certain additional risks. When interest rates rise, certain obligations will be paid off by the obligor more slowly than anticipated causing the value of these securities to fall. This is known as extension risk. In addition, adjustable and fixed rate mortgage-related securities are subject to prepayment risk. When interest rates decline, borrowers may pay off their mortgages sooner than expected. This can reduce the returns of the Fund because the Fund may have to reinvest that money at the lower prevailing interest rates. These securities also are subject to risk of default on the underlying mortgage, particularly during periods of economic downturn.

· Portfolio Turnover Risk. An active trading approach increases the Fund’s costs and may reduce the Fund’s performance. It may also increase the amount of capital gains tax that you have to pay on the Fund’s returns.

Performance

The following bar chart and table provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for 1, 5 and 10 years compare with those of broad measures of market performance. The bar chart shows changes in the Fund’s performance for Class A shares for each calendar year over a ten-year period. Sales charges are not reflected in the bar chart. If sales charges were reflected, returns would be less than those shown. However, the table includes, for share classes with a sales charge, the effect of the maximum sales charge, including any contingent deferred sales charge that would apply to a redemption at the end of the period. How the Fund performed in the past is not necessarily an indication of how the Fund will perform in the future. Updated information on the Fund’s results can be obtained by visiting www.sentinelinvestments.com.

Class A returns shown are based on the 2.25% maximum sales charge and are not adjusted to reflect a maximum 4% sales charge in effect from inception through April 10, 2005 and from June 1, 2006 through July 31, 2010, nor have they been adjusted to reflect the maximum sales charge of 2% in effect from April 11, 2005 to May 31, 2006. If they were, the returns would be lower. The Class C share returns prior to June 1, 2006 (the inception date for the Class C shares) are based on the returns of the Class A shares adjusted to reflect that Class C shares do not charge a front-end sales charge and adjusted for Class C’s estimated higher expenses. Class I share performance prior to May 4, 2007 (the inception date for the Class I shares) is based on the Fund’s Class A share performance, restated to reflect that Class I shares are offered without a sales charge.

Inception: 1986

Annual Total Return for Class A Shares (%) as of December 31

During the ten-year period shown in the above bar chart, the highest return for a quarter was 4.13% (quarter ended June 30, 2010) and the lowest return for a quarter was -1.09% (quarter ended June 30, 2007).

After-tax returns are calculated using the historical highest applicable individual federal marginal income tax rates in effect during the relevant period and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. After-tax returns are shown only for Class A shares and after-tax returns for other classes of shares will vary.

[1] You pay a deferred sales charge of 0.50% on certain redemptions of Class A shares made within twelve months of purchase if you bought them without an initial sales charge as part of an investment of $500,000 or more.

[1] Return after taxes on distributions and sale of fund shares may be higher than return before taxes and/or return after taxes on distributions when a net capital loss occurs upon the redemption of fund shares.

[2] Effective March 30, 2013, the Fund replaced its primary benchmark index (Barclays US Government Bond Index) and secondary benchmark index (Barclays US Mortgage Backed Securities Index) with one index, the Barclays US Government/Mortgage Backed Securities Index, because the Fund believes this one index, which consists of the asset classes in which the Fund invests, is a more appropriate measure of the Fund's investment strategy.

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same.

Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Expense Example Sentinel Small Company Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Class A	617	865	1,132	1,893
Class C	298	612	1,052	2,275
CLASS I	83	259	450	1,002

You would pay the following expenses if you did not redeem your shares:

Expense Example No Redemption (USD $)	1 Year	3 Years	5 Years	10 Years
Sentinel Small Company Fund Class C	198	612	1,052	2,275

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 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 33% of the average value of its portfolio.

Principal Investment Strategies

The Fund normally invests at least 80% of its net assets in small-capitalization companies. For this purpose, small capitalization companies are companies that have, at the time of purchase, market capitalizations of less than $4 billion. The Fund seeks to invest primarily in common stocks of small companies that Sentinel believes are high quality, have superior business models, solid management teams, sustainable growth potential and are attractively valued. The Fund may invest without limitation in foreign securities, although only where the securities are trading in the U.S. or Canada and only where trading is denominated in U.S. or Canadian dollars.

Up to 25% of the Fund’s assets may be invested in securities within a single industry. For portfolio construction purposes, the Fund uses the Standard & Poor’s SmallCap 600 Index as a sector-weighting guide, generally using a plus or minus 25% weighting. The Fund attempts to be well-balanced across major economic sectors. Although the Fund may invest in any economic sector, at times it may emphasize one or more particular sectors.

The Fund would typically sell a security if the portfolio managers believe it is overvalued, if the original investment premise is no longer true, if the market cap exceeds a specified threshold, if the holding size exceeds the portfolio managers’ company or sector weighting guidelines and/or to take advantage of a more attractive investment opportunity. The Fund may also sell a partial position in a security in order to manage the size of the position. A security may also be sold to meet redemptions.

Principal Investment Risks

You could lose money by investing in the Fund. The following is a summary description of the principal risks of investing in the Fund:

· General Foreign Securities Risk. Investments in foreign securities may be affected unfavorably by changes in currency rates or exchange control regulations, or political and/or social instability in a particular foreign country or region.

· Investment Style Risk. The Fund’s growth style of investing may be out of favor at any particular time. The stocks of growth companies may be more sensitive to investor perceptions about company earnings than other stocks and may be more volatile than the market in general.

· Restricted and Illiquid Securities Risk. The Fund will not be able to readily resell illiquid securities and resale of some of these securities may be restricted by law or contractual provisions. The inability to sell these securities at the most opportune time may negatively affect the Fund’s net asset value.

· Sector Risk. Investments in a particular sector may trail returns from other economic sectors.

· Stock Market and Selection Risk. The stock market may go down in value, and may go down sharply and unpredictably. The stocks selected by the portfolio manager may underperform the stock market or other funds with similar investment objectives and investment strategies.

· Stocks of Smaller Companies Risk. The stocks of small- and/or mid-capitalization companies in which the Fund invests typically involve more risk than the stocks of larger companies. These smaller companies may have more limited financial resources and product lines, and may have less seasoned managers. In addition, these stocks may trade less frequently and in lower share volumes, making them subject to wider price fluctuations.

Performance

The following bar chart and table provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for 1, 5 and 10 years compare with those of broad measures of market performance. The bar chart shows changes in the Fund’s performance for Class A shares for each calendar year over a ten-year period. Sales charges are not reflected in the bar chart. If sales charges were reflected, returns would be less than those shown. However, the table includes, for share classes with a sales charge, the effect of the maximum sales charge, including any contingent deferred sales charge that would apply to a redemption at the end of the period. How the Fund performed in the past (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated information on the Fund’s results can be obtained by visiting www.sentinelinvestments.com.

Class I share performance prior to May 4, 2007 (the inception date for the Class I shares) is based on the Fund’s Class A share performance, restated to reflect that Class I shares are offered without a sales charge.

After-tax returns are calculated using the historical highest applicable individual federal marginal income tax rates in effect during the relevant period and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. After-tax returns are shown only for Class A shares and after-tax returns for other classes of shares will vary.

[1] You pay a deferred sales charge of 1% on certain redemptions of Class A shares made within twelve months of purchase if you bought them without an initial sales charge as part of an investment of $1,000,000 or more.

[1] Total Annual Fund Operating Expenses have been restated to reflect current fees. Because of this restatement, the Total Annual Fund Operating Expenses do not correlate to the ratio of expenses to average net assets shown in the Fund's most recent annual report.

[1] Return after taxes on distributions and sale of fund shares may be higher than return before taxes and/or return after taxes on distributions when a net capital loss occurs upon the redemption of fund shares.

[2] The Standard & Poor's SmallCap 600 Index measures the performance of 600 small-cap companies with market capitalization of $300 million to $1.5 billion within the U.S. equity universe. The Fund compares its performance to this index because Fund management believes it is an appropriate alternative measure of the Fund's investment strategy.

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 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 47% of the average value of its portfolio.

Principal Investment Strategies

The Fund normally invests primarily in a broad range of common stocks of companies that Sentinel believes have above-average growth potential.

Sentinel attempts to identify companies that are expected to grow as a result of the potential long-term return from their investment in research, development, capital spending and market expansion. In addition, Sentinel looks for companies that it perceives to be attractively valued relative to their future growth prospects, as well as to that of the market as a whole. When selecting investments focus is on company-specific variables, such as competitive industry dynamics, market leadership, proprietary products and services, and management expertise, as well as on financial characteristics, such as returns on sales and equity, debt/equity ratios and earnings and cash flow growth. Sentinel also analyzes a company’s dividend-paying characteristics when selecting investments with respect to the Fund’s current income objective.

The Fund may invest in any economic sector, and at times may emphasize one or more particular sectors. The Fund may invest up to 25% of its net assets in a single industry. The Fund may invest up to 25% of its net assets in securities of foreign issuers, although only where the securities are trading in the U.S. or Canada and only where trading is denominated in U.S. or Canadian dollars.

Sentinel expects to sell Fund holdings when the fundamentals of a company are perceived to be deteriorating, the valuation of the underlying company relative to its future growth rate appears to have become excessive, or when more attractive alternative investments surface. Sentinel may also sell Fund holdings to meet redemptions.

Principal Investment Risks

You could lose money by investing in the Fund. The following is a summary description of the principal risks of investing in the Fund:

· General Foreign Securities Risk. Investments in foreign securities may be affected unfavorably by changes in currency rates or exchange control regulations, or political and/or social instability in a particular foreign country or region.

· Investment Style Risk. The Fund’s growth style of investing may be out of favor at any particular time. The stocks of growth companies may be more sensitive to investor perceptions about company earnings than other stocks and may be more volatile than the market in general.

Performance

The following bar chart and table provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for 1, 5 and 10 years compare with those of broad measures of market performance. The bar chart shows changes in the Fund’s performance for Class A shares for each calendar year over a ten-year period. Sales charges are not reflected in the bar chart. If sales charges were reflected, returns would be less than those shown. However, the table includes, for share classes with a sales charge, the effect of the maximum sales charge, including any contingent deferred sales charge that would apply to a redemption at the end of the period. How the Fund performed in the past (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated information on the Fund’s results can be obtained by visiting www.sentinelinvestments.com.

The Sentinel Capital Growth Fund began operations on March 17, 2006. Performance for the Fund prior to March 17, 2006 is based on the performance of its predecessor, the Bramwell Growth Fund, which was offered without a sales charge. Performance of Class A shares reflects the current maximum sales charge. Performance of the Class A shares from their inception on March 17, 2006 to June 29, 2012, has not been adjusted to reflect the lower maximum 12b-1 fee in effect prior to March 17, 2006 or the decrease in the maximum 12b-1 fee, effective June 30, 2012, from 0.30% to 0.25%. If it had, those returns would be higher. Performance of Class C shares prior to their inception on March 17, 2006 has been adjusted for the higher estimated expenses of those shares. Performance of the Class I shares from March 17, 2006 to August 27, 2007 (the inception date for the Class I shares) is based on the Fund’s Class A shares, restated to reflect that Class I shares are offered without a sales charge.

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its investment objective by investing in fixed-income securities and in related derivatives, such as interest rate and foreign currency derivatives (futures, options, swaps, options on swaps, and caps and floors). The Fund invests primarily in investment-grade bonds. At least 80% of the Fund’s assets will normally be invested in the following types of bonds and related derivatives:

1. Corporate bonds of varying maturities issued by various U.S. and non-U.S. private-sector entities denominated in U.S. dollars and foreign currencies;

2. Debt securities issued or guaranteed by the U.S. government, its agencies or instrumentalities, including mortgage-backed securities, and by non-U.S. sovereign and quasi-sovereign entities; and

3. Taxable or tax-exempt municipal securities.

The Fund may invest in securities of any duration.

The Fund may invest up to 50% of its assets in below investment-grade bonds.

The Fund may use derivative instruments (e.g., exchange-traded derivatives such as futures and options, and other derivatives such as swap agreements, options on swaps and interest rate caps and floors) in order to hedge various risks, such as interest rate and currency risk. The Fund may use derivative instruments for other investment purposes, such as replicating permitted investments, as long as such investments do not have the effect of leveraging portfolio risks. The Fund is not required to use hedging and may choose not to do so.

The Fund may sell a security if the security is overvalued on a relative basis compared to other securities available in the market, if the fundamentals of the company are deteriorating, or for duration management purposes. The Fund may also sell a security to meet redemptions.

The Fund utilizes an active trading approach, which may result in portfolio turnover greater than 100%.

Risk [Heading]

rr_RiskHeading

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

You could lose money by investing in the Fund. The following is a summary description of the principal risks of investing in the Fund:

· Derivatives Risk. Derivative investments involve counterparty risk (the risk that the counterparty of the derivative transaction will be unable to honor its financial obligation to the Fund), basis risk (the risk that the derivative instrument will not fully offset the underlying positions), and liquidity risk (the risk that the Fund cannot sell the derivative instrument because of an illiquid secondary market). In addition, the portfolio manager may incorrectly forecast the values of securities, currencies or interest rates or other economic factors in using derivatives for the Fund.

·  Foreign Banks and Securities Depositories Risk. Some foreign banks and securities depositories in which the Fund generally holds its foreign securities may be recently organized or new to the foreign custody business. In addition, there may be limited or no regulatory oversight over their operations. Also, the laws of certain countries may put limits on the Fund’s ability to recover its assets if a foreign bank, depository or issuer of a security, or any of their agents, goes bankrupt.

· General Fixed-Income Securities Risk. The market prices of bonds, including those issued by the U.S. government, go up as interest rates fall, and go down as interest rates rise. As a result, the net asset value of the Fund will fluctuate with conditions in the bond markets. In the case of corporate bonds and commercial paper, values may fluctuate as perceptions of credit quality change. In addition, corporate bonds may be downgraded or default. During periods of declining interest rates or for other reasons, bonds may be “called”, or redeemed, by the bond issuer prior to the bond’s maturity date, resulting in the Fund receiving payment earlier than expected. This may reduce the Fund’s income if the proceeds are reinvested at a lower interest rate.

· General Foreign Securities Risk. Investments in foreign securities may be affected unfavorably by changes in currency rates or exchange control regulations, or political or social instability in the particular foreign country or region. The Fund is not required to hedge against changes in foreign currency exchange rates.

· Government Securities Risk. Economic, business, or political developments may affect the ability of government-sponsored guarantors to repay principal and to make interest payments on the securities in which the Fund invests. In addition, certain of these securities, including those issued or guaranteed by FNMA and FHLMC, are not backed by the full faith and credit of the U.S. government.

· Lower-Quality Bonds Risk. Bonds with lower credit ratings are more speculative and likely to default than higher-quality bonds. Lower-rated bonds also tend to fluctuate more widely in value.

· Mortgage-Backed Securities Risk. Mortgage-backed securities represent interests in “pools” of mortgages and are subject to certain additional risks. When interest rates rise, certain obligations will be paid off by the obligor more slowly than anticipated causing the value of these securities to fall. This is known as extension risk. In addition, adjustable and fixed rate mortgage-related securities are subject to prepayment risk. When interest rates decline, borrowers may pay off their mortgages sooner than expected. This can reduce the returns of the Fund because the Fund may have to reinvest that money at the lower prevailing interest rates. These securities also are subject to risk of default on the underlying mortgage, particularly during periods of economic downturn.

· Municipal Securities Risk. Municipal securities can be significantly affected by political changes as well as uncertainties in the municipal market related to taxation, legislative changes, or the rights of municipal security holders.

· Portfolio Turnover Risk. An active trading approach increases the Fund’s costs and may reduce the Fund’s performance. It may also increase the amount of capital gains tax that you have to pay on the Fund’s returns.

After-tax returns are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. After-tax returns are shown only for Class A shares and after-tax returns for other classes of shares will vary.

[1] You pay a deferred sales charge of 0.50% on certain redemptions of Class A shares made within twelve months of purchase if you bought them without an initial sales charge as part of an investment of $500,000 more.

[2] 12b-1 fees have been restated from fiscal year amounts to reflect the maximum fee payable under the applicable distribution plan for such share class. 12b-1 fees are not assessed with respect to shares owned by NLV Financial Corporation or an affiliate ("NLVFin"), which may result in an overall 12b-1 fee charged to all shareholders of less than the maximum for so long as the NLVFin investment is maintained.

[3] The Fund's investment advisor has contractually agreed, effective March 30, 2013, to waive fees and/or reimburse certain expenses in order to limit Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement for Class A shares, on an annualized basis, to 0.89% of average daily net assets attributable to Class A shares through March 31, 2014. This agreement may be terminated upon 90 days' notice by a majority of the non-interested directors of the Fund.
