The Massachusetts Health & Education
Tax-Exempt Trust

The Benefits and Risks of Leveraging

The Massachusetts Health & Education Tax-Exempt Trust utilizes leverage to seek
to enhance the yield and net asset value of its Common Shares. However, these
objectives cannot be achieved in all interest rate environments. To leverage,
the Trust issues Preferred Shares, which pay dividends at prevailing short-term
interest rates, and invests the proceeds in long-term municipal bonds. The
interest earned on these investments, net of dividends to Preferred Shares, is
paid to Common Shareholders in the form of dividends, and the value of these
portfolio holdings is reflected in the per share net asset value of the Trust's
Common Shares. However, in order to benefit Common Shareholders, the yield curve
must be positively sloped; that is, short-term interest rates must be lower than
long-term interest rates. At the same time, a period of generally declining
interest rates will benefit Common Shareholders. If either of these conditions
change, then the risks of leveraging will begin to outweigh the benefits.

To illustrate these concepts, assume a fund's Common Share capitalization of
$100 million and the issuance of Preferred Shares for an additional $50 million,
creating a total value of $150 million available for investment in long-term
municipal bonds. If prevailing short-term interest rates are approximately 3%
and long-term interest rates are approximately 6%, the yield curve has a
strongly positive slope. The fund pays dividends on the $50 million of Preferred
Shares based on the lower short-term interest rates. At the same time, the
fund's total portfolio of $150 million earns the income based on long-term
interest rates. Of course, increases in short- term interest rates would reduce
(and even eliminate) the dividends on the Common Shares.

In this case, the dividends paid to Preferred Shareholders are significantly
lower than the income earned on the fund's long-term investments, and therefore
the Common Shareholders are the beneficiaries of the incremental yield. However,
if short-term interest rates rise, narrowing the differential between short-term
and long-term interest rates, the incremental yield pickup on the Common Shares
will be reduced or eliminated completely. At the same time, the market value of
the fund's Common Shares (that is, its price as listed on the American Stock
Exchange) may, as a result, decline. Furthermore, if long-term interest rates
rise, the Common Shares' net asset value will reflect the full decline in the
price of the portfolio's investments, since the value of the fund's Preferred
Shares does not fluctuate. In addition to the decline in net asset value, the
market value of the fund's Common Shares may also decline.

As a part of its investment strategy, the Trust may invest in certain securities
whose potential income return is inversely related to changes in a floating
interest rate ("inverse floaters"). In general, income on inverse floaters will
decrease when short-term interest rates increase and increase when short-term
interest rates decrease. Investments in inverse floaters may be characterized as
derivative securities and may subject the Trust to the risks of reduced or
eliminated interest payments and losses of invested principal. In addition,
inverse floaters have the effect of providing investment leverage and, as a
result, the market value of such securities will generally be more volatile than
that of fixed-rate, tax-exempt securities. To the extent the Trust invests in
inverse floaters, the market value of the Trust's portfolio and the net asset
value of the Trust's shares may also be more volatile than if the Trust did not
invest in these securities. As of June 30, 2005, the Trust did not invest in
inverse floaters.

Swap Agreements

The Trust may invest in swap agreements, which are over-the-counter contracts in
which one party agrees to make periodic payments based on the change in market
value of a specified bond, basket of bonds, or index in return for periodic
payments based on a fixed or variable interest rate or the change in market
value of a different bond, basket of bonds or index. Swap agreements may be used
to obtain or reduce exposure to a bond or market without owning or taking
physical custody of securities. Swap agreements involve the risk that the party
with whom the Trust has entered into the swap will default on its obligation to
pay the Trust and the risk that the Trust will not be able to meet its
obligations to pay the other party to the agreement.

A Letter From the President

Dear Shareholder

The financial markets continued to face a number of crosscurrents over the past
several months. On June 30, 2005, the Federal Reserve Board (the Fed) increased
the federal funds rate for the ninth consecutive time since June 2004, bringing
the target short-term interest rate to 3.25%. During the same week, first
quarter 2005 U.S. gross domestic product growth was revised upward to 3.8% --
behind the 4.4% annualized growth rate recorded for all of 2004 but ahead of
many economists' expectations. Signs of a slowing economy, coupled with easing
inflationary fears, have prompted some observers to believe that the Fed may
soon end its monetary tightening campaign.

After ending 2004 in a strong rally, U.S. equity markets have struggled to
record meaningful gains in 2005. Continued high oil prices and Fed interest rate
hikes have exerted downward pressure on stocks. Offsetting this somewhat have
been surprisingly strong corporate earnings and lower long-term bond yields.
Outside U.S. borders, results have been mixed. Several European markets have
been performing well despite ongoing economic problems. In Asia, many markets
have benefited from higher economic growth rates and relatively attractive
valuations, although Japanese stocks have struggled as a result of slowing
exports and high oil prices.

In the bond markets, the yield curve flattening "conundrum" continued. As
short-term yields increased in concert with Fed interest rate hikes, yields on
longer-term bonds declined (as their prices, which move opposite yields,
increased). Over the past year, the two-year Treasury yield rose 96 basis points
(.96%) while the 10-year Treasury yield declined 68 basis points. At period-end,
the spread between the two-year and 10-year Treasury yields was just 28 basis
points.

Amid these conditions, the major market benchmarks posted six-month and 12-month
returns as follows:

Entering the second half of 2005, we expect more of the same type of "muddle
through" environment that has befallen financial markets in the first half of
the year. Nevertheless, opportunities do exist and we encourage you to work with
your financial advisor to diversify your portfolio among a variety of asset
types. This can help to diffuse risk while also tapping into the potential
benefits of a broader range of investment alternatives. We thank you for
trusting Merrill Lynch Investment Managers with your investment assets, and we
look forward to serving you in the months and years ahead.

                                        Sincerely,

A Discussion With Your Trust's Portfolio Managers

      As the period progressed and lower-rated bonds outperformed, we
increasingly saw better value from higher-grade credits and began to focus our
investment there.

Describe the market environment relative to municipal bonds.

Over the past six months, long-term bond yields declined as their prices, which
move in the opposite direction, increased. In the meantime, the Federal Reserve
Board (the Fed) continued to raise short-term interest rates at each of its
meetings during the period, lifting the federal funds target to 3.25% on June
30. As longer-term bond yields declined and short-term yields moved upward in
unison with the Fed interest rate hikes, the yield curve continued to flatten.
Over the six months ended June 30, 2005, 30-year U.S. Treasury bond yields
declined 67 basis points to 4.16% and yields on the 10-year Treasury note fell
30 basis points to 3.94%.

In the tax-exempt market, yields on 30-year revenue bonds, as measured by the
Bond Buyer Revenue Bond Index, fell 27 basis points to 4.77%. According to
Municipal Market Data, yields on AAA-rated issues maturing in 30 years declined
35 basis points to 4.26%, while AAA-rated bonds maturing in 10 years saw their
yields decline 7 basis points to 3.45%.

The declining tax-exempt bond yields have prompted municipalities to both issue
new debt and refund outstanding, higher-couponed issues. During the six-month
period, more than $206 billion in new municipal bonds was underwritten, an
increase of 8.6% versus the same six months in 2004. The new issuance was
boosted by a greater than 55% increase in refunding issues, which have been
heavily weighted in the 10-year - 20-year maturity range to lower the overall
interest cost of the refunding issue. This concentration has put pressure on
intermediate tax-exempt bond yields while supporting longer-term bond prices.

Investor demand for municipal product generally has remained positive. According
to statistics from the Investment Company Institute, through May 31, 2005,
year-to-date net new cash flows into long-term municipal bond funds have
exceeded $1.35 billion. This represents a significant improvement from the $7.86
billion net outflow seen during the same period in 2004. Recent June weekly
figures from AMG Data Service have also shown continued positive flows.
Throughout much of the past six months, high yield tax-exempt bond funds have
been the principal target for these new cash inflows. During June, these
lower-rated/non-rated bond funds received an average of $150 million per week.
The need to invest these cash flows has led to very strong demand for
lower-rated issues and a consequent narrowing of credit spreads. Additionally,
thus far in 2005, the percentage of new issues bearing an insurer's guarantee
has risen to nearly 60%, up from 53.6% during the same period a year ago. The
increasing percentage of insured issuance has further reduced the availability
of lower-rated municipal securities, lending more support to higher prices for
these issues.

Describe conditions in the Commonwealth of Massachusetts.

The Massachusetts economy continued to improve, with rising revenue collections
and a May 2005 unemployment rate of 4.9%, below the national average of 5.1%.
The commonwealth's budget for the 2005 fiscal year projected financial reserves
of just over $800 million, but as a result of strong revenue performance, the
most recent estimates were approaching $1.8 billion at period-end. For the first
half of the 2005 fiscal year, tax collections were 10% higher than during the
same period a year earlier.

Massachusetts's budget adopted for fiscal year 2006 assumes a $600 million
drawdown of the commonwealth's budget stabilization funds, though this drawdown
conservatively assumes flat revenue growth. The commonwealth's debt levels,
however, remain the second-highest in the United States, due in part to the
costs of the Central Artery/Tunnel project (the "Big Dig"). The project's
completion considerably reduces the financial risk to the commonwealth, although
some uncertainty exists around construction-related problems associated with
tunnel leakage. Also, the School Building Assistance program, which changes how
school construction is financed in the commonwealth, is authorized to issue $10
billion of debt and will continue to add to current debt levels.

How did the Trust perform during the period?

For the six-month period ended June 30, 2005, the Common Shares of Massachusetts
Health and Education Tax-Exempt Trust had net annualized yields of 5.57% and
5.35%, based on a period-end per share net asset value of $14.12 and a per share
market price of $14.70, respectively, and $.390 per share income dividends. Over
the same period, the total investment return on the Trust's Common Shares was
+5.62%, based on a change in per share net asset value from $13.74 to $14.12,
and assuming reinvestment of all distributions.


4    THE MASSACHUSETTS HEALTH & EDUCATION TAX-EXEMPT TRUST    JUNE 30, 2005


The Trust's performance benefited from a relatively large position in lower
investment grade and, to a lesser extent, non-investment grade bonds. Besides
adding to the Trust's income stream, returns from these lower-rated issues
increased as credit spreads -- the amount of additional income investors receive
for taking on credit risk -- continued to tighten during the period.

Detracting from performance was the Trust's relatively low leverage ratio -- at
just over 23% of portfolio assets at period-end. When interest rates are
falling, portfolios with a higher degree of leverage tend to outperform those
with less leverage, and vice versa. During the past six months, long-term
interest rates fell more than we expected, and being relatively underleveraged
detracted from performance.

For a description of the Trust's total investment return based on a change in
the per share market value of the Trust's Common Shares (as measured by the
trading price of the Trust's shares on the American Stock Exchange), and
assuming reinvestment of dividends, please refer to the Financial Highlights
section of this report. As a closed-end fund, the Trust's shares may trade in
the secondary market at a premium or discount to the Trust's net asset value. As
a result, total investment returns based on changes in the market value of the
Trust's Common Shares can vary significantly from total investment return based
on changes in the Trust's net asset value.

What changes were made to the portfolio during the period?

We generally looked to invest in longer-dated bonds, as we did not believe that
long-term interest rates were likely to rise in line with short-term interest
rates during the period. Based on our expectations, we sold selected shorter
bonds when appropriate and reinvested the proceeds in longer-dated holdings. In
fact, longer-bond yields fell during the period as short-term interest rates
increased. Because bond prices move in the opposite direction of yields, this
meant that longer-term bonds significantly outperformed short-term bonds, and
our focus further out on the curve paid off.

Although the portfolio had an above-market weighting in lower-rated bonds, most
of our new purchases during the period consisted of bonds with credit ratings of
A or higher. As the period progressed and lower-rated bonds outperformed, we
increasingly saw better relative value in higher-grade credits. By period-end,
approximately 83% of the Trust's assets were rated investment grade (BBB or
better).

Otherwise, our primary focus throughout the period was on following the Trust's
mandate of investing in Massachusetts not-for-profit health care and education
bonds. We had little trouble finding suitable securities for investment and, at
period-end, 91% of the portfolio was held in these sectors, up from 86% six
months earlier.

For the six months ended June 30, 2005, the Trust's Auction Preferred Shares
(APS) had an average yield of 1.59%. The Trust's borrowing costs moved somewhat
higher during the period, predominantly as a result of the Fed's continued
interest rate hikes, but also reflecting seasonal (tax-time) factors as
investors redeemed monies from their short-term tax-exempt investments to pay
their tax liabilities. Still, the tax-exempt yield curve remained relatively
steep and continued to generate an income benefit to the holders of Common
Shares from the leveraging of Preferred Shares. However, should the spread
between short-term and long-term interest rates narrow, the benefits of
leveraging will decline and, as a result, reduce the yield on the Fund's Common
Shares. At the end of the period, the Trust's leverage amount, due to APS, was
22.66% of total net assets, before the deduction of Preferred Shares. (For a
more complete explanation of the benefits and risks of leveraging, see page 2 of
this report to shareholders.)

How would you characterize the Trust's position at the close of the period?

As of period-end, the Trust remained fully invested and reflected our generally
neutral view on interest rates. We would expect dividends on the Trust's
Preferred Shares to rise in line with further "measured" Fed interest rate
increases. However, we do not expect long-term yields on Massachusetts municipal
bonds to rise significantly. We remain relatively comfortable with the
portfolio's positioning -- specifically, its increased emphasis on high-quality
assets and longer-term bonds. Although we think the Trust is well structured, we
will continue to monitor conditions in the municipal market and will not
hesitate to make portfolio changes when we believe they are warranted.

12   THE MASSACHUSETTS HEALTH & EDUCATION TAX-EXEMPT TRUST    JUNE 30, 2005


Notes to Financial Statements

1. Significant Accounting Policies:

The Massachusetts Health & Education Tax-Exempt Trust (the "Trust") is
registered under the Investment Company Act of 1940, as amended, as a
non-diversified, closed-end management investment company. The Trust's financial
statements are prepared in conformity with U.S. generally accepted accounting
principles, which may require the use of management accruals and estimates.
Actual results may differ from these estimates. These unaudited financial
statements reflect all adjustments, which are, in the opinion of management,
necessary to present a fair statement of the results for the interim period. All
such adjustments are of a normal, recurring nature. The Trust determines and
makes available for publication the net asset value of its Common Shares on a
daily basis. The Trust's Common Shares are listed on the American Stock Exchange
under the symbol MHE. The following is a summary of significant accounting
policies followed by the Trust.

(a) Valuation of investments -- Municipal bonds are traded primarily in the
over-the-counter ("OTC") markets and are valued at the last available bid price
in the OTC market or on the basis of values as obtained by a pricing service.
Pricing services use valuation matrixes that incorporate both dealer-supplied
valuations and valuation models. The procedures of the pricing service and its
valuations are reviewed by the officers of the Trust under the general direction
of the Board of Trustees. Such valuations and procedures are reviewed
periodically by the Board of Trustees of the Trust. Financial futures contracts
and options thereon, which are traded on exchanges, are valued at their closing
prices as of the close of such exchanges. Options written or purchased are
valued at the last sale price in the case of exchange-traded options. In the
case of options traded in the OTC market, valuation is the last asked price
(options written) or the last bid price (options purchased). Swap agreements are
valued by quoted fair values received daily by the Trust's pricing service.
Short-term investments with a remaining maturity of 60 days or less are valued
at amortized cost, which approximates market value, under which method the
investment is valued at cost and any premium or discount is amortized on a
straight line basis to maturity. Investments in open-end investment companies
are valued at their net asset value each business day. Securities and other
assets for which market quotations are not readily available are valued at fair
value as determined in good faith by or under the direction of the Board of
Trustees of the Trust.

(b) Derivative financial instruments -- The Trust may engage in various
portfolio investment strategies both to increase the return of the Trust and to
hedge, or protect, its exposure to interest rate movements and movements in the
securities markets. Losses may arise due to changes in the value of the contract
or if the counterparty does not perform under the contract.

o     Financial futures contracts -- The Trust may purchase or sell financial
      futures contracts and options on such futures contracts. Futures contracts
      are contracts for delayed delivery of securities at a specific future date
      and at a specific price or yield. Upon entering into a contract, the Trust
      deposits and maintains as collateral such initial margin as required by
      the exchange on which the transaction is effected. Pursuant to the
      contract, the Trust agrees to receive from or pay to the broker an amount
      of cash equal to the daily fluctuation in value of the contract. Such
      receipts or payments are known as variation margin and are recorded by the
      Trust as unrealized gains or losses. When the contract is closed, the
      Trust records a realized gain or loss equal to the difference between the
      value of the contract at the time it was opened and the value at the time
      it was closed.

o     Options -- The Trust may write covered call options and purchase put
      options. When the Trust writes an option, an amount equal to the premium
      received by the Trust is reflected as an asset and an equivalent
      liability. The amount of the liability is subsequently marked-to-market to
      reflect the current market value of the option written. When a security is
      purchased or sold through an exercise of an option, the related premium
      paid (or received) is added to (or deducted from) the basis of the
      security acquired or deducted from (or added to) the proceeds of the
      security sold. When an option expires (or the Trust enters into a closing
      transaction), the Trust realizes a gain or loss on the option to the
      extent of the premiums received or paid (or gain or loss to the extent the
      cost of the closing transaction exceeds the premium paid or received).

      Written and purchased options are non-income producing investments.


     THE MASSACHUSETTS HEALTH & EDUCATION TAX-EXEMPT TRUST    JUNE 30, 2005   13


Notes to Financial Statements (concluded)

o     Forward interest rate swaps -- The Trust may enter into forward interest
      rate swaps. In a forward interest rate swap, the Trust and the
      counterparty agree to make periodic net payments on a specified notional
      contract amount, commencing on a specified future effective date, unless
      terminated earlier. When the agreement is closed, the Trust records a
      realized gain or loss in an amount equal to the value of the agreement.

(c) Income taxes -- It is the Trust's policy to comply with the requirements of
the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no federal income tax provision is required.

(d) Security transactions and investment income -- Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Realized gains and losses on security transactions are determined on the
identified cost basis. Dividend income is recorded on the ex-dividend dates. The
Trust amortizes all premiums and discounts on debt securities.

(e) Dividends and distributions -- Dividends from net investment income are
declared daily and paid monthly. Distributions of capital gains are recorded on
the ex-dividend dates.

2. Investment Advisory Agreement and Transactions with Affiliates:

The Trust has entered into an advisory agreement with Fund Asset Management,
L.P. ("FAM") and an administrative agreement with Princeton Administrators, L.P.
("Princeton"). The general partner of FAM is Princeton Services, Inc. ("PSI"),
an indirect, wholly-owned subsidiary of Merrill Lynch & Co., Inc. ("ML & Co."),
which is the limited partner. FAM and Princeton are owned and controlled by ML &
Co.

FAM is responsible for the management of the Trust's portfolio and provides the
necessary personnel, facilities, equipment and certain other services necessary
to the operations of the Trust. For such services, the Trust pays a monthly fee
at an annual rate of .35% of the Trust's average daily net assets, including
proceeds from the issuance of Preferred Shares.

The Trust pays Princeton a monthly fee at an annual rate of .15% of the Trust's
average daily net assets, including proceeds from the issuance of Preferred
Shares, for the performance of administrative services (other than investment
advice and related portfolio activities) necessary for the operation of the
Trust.

Certain officers and/or trustees of the Trust are officers and/or directors of
FAM, PSI, Princeton, and/or ML & Co.

3. Investments:

Purchases and sales of investments, excluding short-term securities, for the six
months ended June 30, 2005 were $3,848,803 and $2,515,160, respectively.

4. Share Transactions:

Common Shares

The Trust is authorized to issue an unlimited number of Common Shares, par value
$.01 per share. Shares issued and outstanding during the six months ended June
30, 2005 and the year ended December 31, 2004 increased by 2,474 and 6,200,
respectively, as a result of reinvestment of dividends and distributions.

Preferred Shares

The Trust is authorized to issue an unlimited number of Preferred Shares, par
value $.01 per share. In addition, the Trust has authorized 400 shares of
Auction Preferred Shares, par value $.01 per share. Auction Preferred Shares are
redeemable shares of Preferred Shares of the Trust, with a par value of $.01 per
share and a liquidation preference of $50,000 per share, plus accrued and unpaid
dividends, that entitle their holders to receive cash dividends at an annual
rate that may vary for the successive dividend periods. The yield in effect at
June 30, 2005 was 2.10%.

5. Subsequent Event:

The Trust paid a tax-exempt income dividend to holders of Common Shares in the
amount of $.065000 per share on July 28, 2005 to shareholders of record on July
14, 2005.

The Massachusetts Health & Education Tax-Exempt Trust seeks to provide
shareholders with as high a level of current income exempt from both regular
federal income taxes and Massachusetts personal income taxes as is consistent
with the preservation of shareholders' capital. The Trust seeks to achieve its
investment objective by investing primarily in Massachusetts tax-exempt
obligations issued on behalf of participating not-for-profit institutions. The
Trust will continue to invest primarily in "investment grade" obligations. The
Trust is intended to be a long-term investment and not a short-term trading
vehicle.

This report, including the financial information herein, is transmitted to
shareholders of The Massachusetts Health & Education Tax-Exempt Trust for their
information. It is not a prospectus. Past performance results shown in this
report should not be considered a representation of future performance. The
Trust has leveraged its Common Shares and intends to remain leveraged by issuing
Preferred Shares to provide the Common Shareholders with a potentially higher
rate of return. Leverage creates risks for Common Shareholders, including the
likelihood of greater volatility of net asset value and market price of shares
of the Common Shares, and the risk that fluctuations in the short-term dividend
rates of the Preferred Shares may affect the yield to Common Shareholders.
Statements and other information herein are as dated and are subject to change.

A description of the policies and procedures that the Trust uses to determine
how to vote proxies relating to portfolio securities is available (1) without
charge, upon request, by calling toll-free 1-800-MER-FUND (1-800-637-3863); (2)
at www.mutualfunds.ml.com; and (3) on the Securities and Exchange Commission's
Web site at http://www.sec.gov. Information about how the Trust voted proxies
relating to securities held in the Trust's portfolio during the most recent
12-month period ended June 30 is available (1) at www.mutualfunds.ml.com and (2)
