Item 1. Report to Stockholders.

Morgan Stanley Quality Municipal Investment Trust
LETTER TO THE SHAREHOLDERS - APRIL 30, 2003

Dear Shareholder:

During the six-month period ended April 30, 2003, U.S. economic growth was
positive but disappointing. The pattern of the recovery remained uneven with
many indicators fluctuating between strength and weakness. The military conflict
in Iraq and the ongoing war against terrorism cast a shadow over the economy and
the financial markets. The sluggish economy and uncertain geopolitical outlook
generally favored bonds and led to lower interest rates throughout the period.

Consumer spending was the best-performing sector of the economy last year.
Mortgage refinancing and low auto loan rates helped keep Americans buying. By
year-end, a growing apprehension about Iraq began to dominate investor sentiment
and consumer confidence waned. The most noticeable impact of the evolving war
risk was a spike in oil prices that had a dampening effect similar to a tax
increase. Confidence was also shaken when unemployment reached an eight-year
high. To guard against further downside risks, the Federal Reserve Board lowered
the federal funds rate from 1.75 to 1.25 percent in early November. This marked
the first change by the central bank in almost a year. Early in 2003 the Bush
administration proposed several tax relief measures to bolster the economy.
Uncertainty prior to the invasion of Iraq slowed economic activity in March.
However, resolution of the conflict prompted the financial markets again to
focus on the economic recovery.

Municipal Market Conditions

The yield on the 30-year insured municipal bond index continued to trend lower
over the six-month period ended April 30, 2003. The yield declined from a high
of 5.10 percent in November 2002 to a low of 4.70 percent in April. Throughout
the period, the municipal yield curve was at or near its steepest level in 25
years. The pickup along the yield curve for extending maturities from one to 30
years was 350 basis points on April 30, 2003.

The ratio of municipal yields as a percentage of U.S. Treasury yields is used to
gauge the relative value of municipals. In October 2002 the ratio of 30-year
insured municipal bond yields to 30-year Treasuries moved above 100 percent,
remaining there through the first quarter of 2003. In April the ratio fell to 99
percent as the Treasury flight-to-quality rally subsided. This still-high ratio
indicated that municipals were relatively cheaper than Treasuries.

The President's tax proposals, which included elimination of taxation on
dividend income and acceleration of a reduction in tax brackets, affected the
municipal market. The tax-exempt bond

Morgan Stanley Quality Municipal Investment Trust
LETTER TO THE SHAREHOLDERS - APRIL 30, 2003 continued

market reacted to potential tax-reform risk by adjusting the relationship of
tax-exempt issues to taxables.

Long-term municipal volume, as reported in The Bond Buyer, increased to a record
$357 billion in 2002 as state and local governments took advantage of lower
interest rates to meet cash flow needs and refinance outstanding debt. In the
first four months of 2003, new-issue volume reached a record $113 billion, 21
percent above last year's level. We expect this pace to continue throughout the
year as budgetary problems force states and municipalities to borrow.
California's share of national volume increased to 19 percent. New York,
Florida, Texas and New Jersey, the next largest states in terms of issuance,
represented an additional 28 percent of the national total.

Performance

The net asset value (NAV) of Morgan Stanley Quality Municipal Investment Trust
(IQT) increased from $15.23 to $15.59 per share for the six months ended April
30, 2003. Based on this change plus the reinvestment of tax-free dividends
totaling $0.48 per share and a long-term capital gain distribution of $0.09 per
share, the Trust's total NAV return was 6.61 percent. IQT's price on the New
York Stock Exchange (NYSE) increased from $14.08 to $14.43 per share during the
same period. Based on this change plus the reinvestment of dividends and
distributions, IQT's total market value return was 6.74 percent. On April 30,
2003 IQT's market value price was at a 7.44 percent discount to its NAV.

Monthly dividends for the second quarter of 2003 declared in March were
unchanged at $0.080 per share. The dividend reflects the level of the Trust's
undistributed net investment income and projected earnings. The Trust's level of
undistributed net investment income was $0.157 per share on April 30, 2003,
versus $0.189 per share six months earlier. (Past performance is no guarantee of
future results.)

Portfolio Structure

The Trust's total net assets of $362 million, including outstanding Auction Rate
Preferred Shares (ARPS), were diversified among 12 long-term sectors and 62
credits. Issues in three essential service sectors: general obligation, water
and sewer, and transportation accounted for 53 percent of the long-term
portfolio. The five states with the largest holdings -- New York, Florida,
Texas, New Jersey and Illinois -- collectively represented 48 percent of total
investments.

Importantly, the Trust has avoided bonds secured by tobacco settlement payments.
Many states have issued bonds backed by their entitlement to revenues from the
Master Settlement Agreement

with tobacco companies. A class action judgment against Philip Morris, a major
participant in the agreement, has created uncertainty about the company's
ability to meet its obligations.

At the end of April the portfolio's average maturity was 19 years. In the first
quarter of 2003 the Trust sold five and ten year U.S. Treasury futures to hedge
the portfolio against potential increases in interest rates. This action reduced
IQT's duration, a measure of sensitivity to interest rate changes, from 7.9 to
7.7 years. The accompanying charts provide current information on the
portfolio's credit ratings, maturity distribution and sector concentrations.
Optional redemption provisions by year of call and respective cost (book) yields
are also charted.

The Trust's procedure for reinvestment of all dividends and distributions on
common shares is through purchases in the open market. This method helps support
the market value of the Trust's shares. In addition, we would like to remind you
that the Trustees have approved a procedure whereby the Trust may, when
appropriate, purchase shares in the open market or in privately negotiated
transactions at a price not above market value or net asset value, which ever is
lower at the time of purchase. The Trust may also utilize procedures to reduce
or eliminate the amount of outstanding ARPS, including their purchase in the
open market or in privately negotiated transactions. During the six-month period
ended April 30, 2003 the Trust purchased and retired 216,200 shares of common
stock at a weighted average market discount of 7.85 percent.

The Impact of Leveraging

As discussed in previous reports, the total income available for distribution to
common shareholders includes incremental income provided by the Trust's
outstanding ARPS. ARPS dividends reflect prevailing short-term interest rates on
maturities normally ranging from one week to two years. Incremental income to
common shareholders depends on two factors. The first factor is the amount of
ARPS outstanding, while the second is the spread between the portfolio's cost
yield and ARPS expenses (ARPS auction rate and expenses). The greater the spread
and the amount of ARPS outstanding, the greater the amount of incremental income
available for distribution to common shareholders. The level of net investment
income available for distribution to common shareholders varies with the level
of short-term interest rates. ARPS leverage also increases the price volatility
of common shares and has the effect of extending portfolio duration.

Current earnings continued to benefit from lower short-term borrowing costs of
ARPS. During this six-month period, ARPS leverage contributed approximately
$0.10 per share to common share earnings applicable to common shareholders. IQT
has two ARPS series totaling

$105 million and representing 29 percent of total net assets. Series A is
currently a two-year auction maturing in September 2004 yielding 1.90 percent.
The yield on IQT's weekly ARPS series ranged between 0.70 and 1.34 percent.

We appreciate your ongoing support of Morgan Stanley Quality Municipal
Investment Trust and look forward to continuing to serve your investment needs.

Morgan Stanley Quality Municipal Investment Trust
NOTES TO FINANCIAL STATEMENTS - APRIL 30, 2003 (UNAUDITED)

1. Organization and Accounting Policies

Morgan Stanley Quality Municipal Investment Trust (the "Trust") is registered
under the Investment Company Act of 1940, as amended, as a diversified,
closed-end management investment company. The Trust's investment objective is to
provide current income which is exempt from federal income tax. The Trust was
organized as a Massachusetts business trust on July 2, 1991 and commenced
operations on September 27, 1991.

The following is a summary of significant accounting policies:

A. Valuation of Investments -- (1) portfolio securities are valued by an outside
independent pricing service approved by the Trustees. The pricing service uses
both a computerized grid matrix of tax-exempt securities and evaluations by its
staff, in each case based on information concerning market transactions and
quotations from dealers which reflect the bid side of the market each day. The
portfolio securities are thus valued by reference to a combination of
transactions and quotations for the same or other securities believed to be
comparable in quality, coupon, maturity, type of issue, call provisions, trading
characteristics and other features deemed to be relevant; (2) futures are valued
at the latest sale price on the commodities exchange on which they trade unless
the Trustees determine that such price does not reflect their market value, in
which case they will be valued at their fair value as determined in good faith
under procedures established by and under the supervision of the Trustees; and
(3) short-term debt securities having a maturity date of more than sixty days at
time of purchase are valued on a mark-to-market basis until sixty days prior to
maturity and thereafter at amortized cost based on their value on the 61st day.
Short-term debt securities having a maturity date of sixty days or less at the
time of purchase are valued at amortized cost.

B. Accounting for Investments -- Security transactions are accounted for on the
trade date (date the order to buy or sell is executed). Realized gains and
losses on security transactions are determined by the identified cost method.
Discounts are accreted and premiums are amortized over the life of the
respective securities. Interest income is accrued daily.

C. Futures Contracts -- A futures contract is an agreement between two parties
to buy and sell financial instruments or contracts based on financial indices at
a set price on a future date. Upon entering into such a contract, the Trust is
required to pledge to the broker cash, U.S. Government securities or other
liquid portfolio securities equal to the minimum initial margin requirements of
the applicable futures exchange. 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 the value of

                                        17

Morgan Stanley Quality Municipal Investment Trust
NOTES TO FINANCIAL STATEMENTS - APRIL 30, 2003 (UNAUDITED) continued

the contract. Such receipts or payments known as variation margin are recorded
by the Trust as unrealized gains and losses. Upon closing of the contract, the
Trust realizes a 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.

D. Federal Income Tax Policy -- 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 and nontaxable
income to its shareholders. Accordingly, no federal income tax provision is
required.

E. Dividends and Distributions to Shareholders -- Dividends and distributions to
shareholders are recorded on the ex-dividend date. The amount of dividends and
distributions from net investment income and net realized capital gains are
determined in accordance with federal income tax regulations which may differ
from generally accepted accounting principles. These "book/tax" differences are
either considered temporary or permanent in nature. To the extent these
differences are permanent in nature, such amounts are reclassified within the
capital accounts based on their federal tax-basis treatment; temporary
differences do not require reclassification. Dividends and distributions which
exceed net investment income and net realized capital gains for financial
reporting purposes but not for tax purposes are reported as dividends in excess
of net investment income or distributions in excess of net realized capital
gains. To the extent they exceed net investment income and net realized capital
gains for tax purposes, they are reported as distributions of paid-in-capital.

F. Use of Estimates -- The preparation of financial statements in accordance
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts and disclosures.
Actual results could differ from those estimates.

2. Investment Management Agreement

Pursuant to an Investment Management Agreement with Morgan Stanley Investment
Advisors Inc. ("the Investment Manager"), the Trust pays the Investment Manager
a management fee, calculated weekly and payable monthly, by applying the annual
rate of 0.35% to the Trust's weekly net assets including preferred shares.

3. Security Transactions and Transactions With Affiliates

The cost of purchases and proceeds from sales of portfolio securities, excluding
short-term investments, for the six months ended April 30, 2003 aggregated
$30,291,020 and $37,750,875, respectively.

Morgan Stanley Trust, an affiliate of the Investment Manager, is the Trust's
transfer agent.

The Trust has an unfunded noncontributory defined benefit pension plan covering
all independent Trustees of the Trust who will have served as independent
Trustees for at least five years at the time of retirement. Benefits under this
plan are based on years of service and compensation during the last five years
of service. Aggregate pension costs for the six months ended April 30, 2003
included in Trustees' fees and expenses in the Statement of Operations amounted
to $3,354. At April 30, 2003, the Trust had an accrued pension liability of
$53,004 which is included in accrued expenses in the Statement of Assets and
Liabilities.

4. Preferred Shares of Beneficial Interest

The Trust is authorized to issue up to 1,000,000 non-participating preferred
shares of beneficial interest having a par value of $.01 per share, in one or
more series, with rights as determined by the Trustees, without approval of the
common shareholders. The Trust has issued Series A and Series B Auction Rate
Preferred Shares ("Preferred Shares") which have a liquidation value of $50,000
per share plus the redemption premium, if any, plus accumulated but unpaid
dividends, whether or not declared, thereon to the date of distribution. The
Trust may redeem such shares, in whole or in part, at the original purchase
price of $50,000 per share plus accumulated but unpaid dividends, whether or not
declared, thereon to the date of redemption.

Dividends, which are cumulative, are reset through auction procedures.

dividends to Series A and B at rates ranging from 1.05% to 1.90% in the
aggregate amount of $158,578.

The Trust is subject to certain restrictions relating to the preferred shares.
Failure to comply with these restrictions could preclude the Trust from
declaring any distributions to common

  $0.08    June 6, 2003  June 20, 2003

cash balances maintained by the Trust.

Morgan Stanley Quality Municipal Investment Trust
NOTES TO FINANCIAL STATEMENTS - APRIL 30, 2003 (UNAUDITED) continued

9. Risks Relating to Certain Financial Instruments

The Trust may invest a portion of its assets in residual interest bonds, which
are inverse floating rate municipal obligations. The prices of these securities
are subject to greater market fluctuations during periods of changing prevailing
interest rates than are comparable fixed rate obligations.

At April 30, 2003, the Trust held positions in residual interest bonds having a
total value of $7,825,560, which represents 3.0% of the Trust's net assets
applicable to common shareholders.

To hedge against adverse interest rate changes, the Trust may invest in
financial futures contracts or municipal bond index futures contracts ("futures
contracts").

These futures contracts involve elements of market risk in excess of the amount
reflected in the Statement of Assets and Liabilities. The Trust bears the risk
of an unfavorable change in the value of the underlying securities.

At April 30, 2003, the Trust had outstanding futures contracts.
