NAV per share is determined by dividing the value of the trust's portfolio
securities, cash and other assets, less all liabilities, by the total number of
common shares outstanding. The common share market price is the price the market
is willing to pay for shares of the trust at a given time. Common share market
price is influenced by a range of factors, including supply and demand and
market conditions. Total return assumes an investment at the beginning of the
period, reinvestment of all distributions for the period in accordance with the
trust's dividend reinvestment plan, and sale of all shares at the end of the
period.

The Lehman Brothers Municipal Bond Index is a broad-based statistical composite
of municipal bonds. The index does not include any expenses, fees or sales
charges, which would lower performance. The index is unmanaged and should not be
considered an investment. It is not possible to invest directly in an index.

Trust Report

FOR THE 6-MONTH PERIOD ENDED APRIL 30, 2005

Van Kampen Trust for Insured Municipals is managed by the Adviser's Municipal
Fixed Income team.(1) Current members include Joseph Piraro and Robert Wimmel,
Vice Presidents of the Adviser; and John Reynoldson, Executive Director of the
Adviser.

MARKET CONDITIONS

The six-month period ended April 30, 2005, was characterized by continued
short-term interest rate increases. As crude oil prices reached record highs,
the prospect of rising inflation also cast a shadow. The Federal Open Market
Committee (the "Fed") raised the federal funds target rate 100 basis points
during the period through a series of four "measured" 0.25 percent tightenings
to 2.75 percent by the end of April. Although rates in the short and
intermediate areas of the yield curve shifted upward as the Fed tightened, long-
term interest rates fell as buyers did not seem deterred by the prospect of
rising inflation. As a result, the yield curve (the difference between short and
longer-term yields) flattened and the long end of the municipal market handily
outperformed the shorter end.

The municipal market in total posted positive returns during the period, though
it was not uniformly strong. In contrast to the strong showing by longer-term
bonds, shorter-term municipals were hampered by the Fed's tightening and turned
in a flat to slightly negative showing. Within the investment-grade segment of
the market, yield differentials between BBB-rated and AAA-rated municipal
securities were slightly wider, though BBB-rated securities still outperformed
high grades due to their higher coupons, while securities rated below investment
grade strongly outperformed as investors sought out their higher yields.

The Fed's interest rate hikes did not appear to dampen investors' appetites for
municipal bonds, as net inflows into municipal bond funds topped $290 million
during the period. The supply of new issues was modest during the closing months
of 2004 (the first two months of the period) before soaring in the opening
months of 2005 as long-term issuers rushed to bring securities to market in
anticipation of additional interest rate increases in the near term.

PERFORMANCE ANALYSIS

The trust's return can be calculated based upon either the market price or the
net asset value (NAV) of its shares. NAV per share is determined by dividing the
value of the trust's portfolio securities, cash and other assets, less all
liabilities, by the total number of common shares outstanding, while market
price reflects the supply and demand for the shares. As a result, the two
returns can differ, as they did during the reporting period. On an NAV basis,
the trust outperformed its benchmark index, the Lehman Brothers Municipal Bond
Index. On a market price basis, the trust underperformed its benchmark.

AND INDEX DEFINITION.

The trust uses leverage to enhance its dividend to common shareholders. The
trust borrows money at short-term rates through the issuance of preferred
shares. The proceeds are reinvested in longer-term securities, taking advantage
of the difference between short- and longer-term rates. The Fed's policy of
raising interest rates throughout the period made the trust's borrowing activity
more expensive. These expenses, however, were more than offset by the positive
performance of the bonds held by the trust.

One of our primary strategies in managing the trust during the period was to
take advantage of compelling opportunities in the 25- to 30-year segment of the
market. We focused here on purchasing securities with premium (that is, above-
market) coupons and moderate interest rate sensitivity. Our purchases of these
securities were funded by the proceeds of sales of several shorter-maturity
positions, many of which had been refunded during the period. This was part of
our ongoing strategy of positioning the trust for an environment of rising
short-term interest rates by limiting the trust's exposure to that segment of
the market.

At the end of the period, airport bonds represented the largest sector exposure
of the portfolio, totaling approximately 18 percent of assets. Although airport
bonds have received negative publicity, our analysis is that the airports will
persevere, regardless of which airlines survive. We continued to favor the
essential services segments of the market. Public builders and general purpose
rounded out the top three sectors.

                                                                               3


In turn, we avoided the housing sector out of concerns about those bonds'
structural characteristics. We also avoided zero coupon bonds. The trust
remained well diversified geographically, with no one state or region dominating
the portfolio. Many of our purchases were either from states with high taxes
(such as California or New York), and therefore, strong demand for their bonds;
or from states (such as Illinois) that lack dual tax-exempt status. Because they
do not carry dual tax-exemption, bonds in this latter group typically offered
higher yields than other higher-tax states. Because the trust invests
exclusively in bonds that offer the credit enhancement of insurance, the entire
portfolio of long-term investments was rated AAA at the close of the period.

There is no guarantee the security sectors mentioned will continue to perform
well or be held by the trust in the future.

(a) As required, effective November 1, 2001, the Trust has adopted the
    provisions of the AICPA Audit and Accounting Guide for Investment Companies
    and began accreting market discount on fixed income securities. The effect
    of this change for the year ended October 31, 2002 was to increase net
    investment income per share by less than $.01, decrease net realized and
    unrealized gains and losses per share by less than $.01, and increase the
    ratio of net investment income to average net assets applicable to common
    shares by .01%. Per share, ratios and supplemental data for periods prior to
    October 31, 2002 have not been restated to reflect this change in
    presentation.

(b) Total return assumes an investment at the common share market price at the
    beginning of the period indicated, reinvestment of all distributions for the
    period in accordance with the Trust's dividend reinvestment plan, and sale
    of all shares at the closing common share market price at the end of the
    period indicated.

(c) Ratios do not reflect the effect of dividend payments to preferred
    shareholders.

(d) Ratios reflect the effect of dividend payments to preferred shareholders.

(e) Calculated by subtracting the Trust's total liabilities (not including the
    preferred shares) from the Trust's total assets and dividing this by the
    number of preferred shares outstanding.

(f) Amount is less than $.01

VAN KAMPEN TRUST FOR INSURED MUNICIPALS

NOTES TO FINANCIAL STATEMENTS -- APRIL 30, 2005 (UNAUDITED)

1. SIGNIFICANT ACCOUNTING POLICIES

Van Kampen Trust for Insured Municipals (the "Trust") is registered as a
diversified, closed-end management investment company under the Investment
Company Act of 1940, as amended. The Trust's investment objective is to provide
a high level of current income exempt from federal income tax, consistent with
preservation of capital. In normal market conditions, the Trust intends to
invest substantially all of its assets in municipal securities which are covered
by insurance with respect to the timely payment of principal and interest. The
Trust commenced investment operations on January 24, 1992.

    The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements. The
preparation of financial statements in conformity with accounting principles
generally accepted in the United States of America requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.

A. SECURITY VALUATION Municipal bonds are valued by independent pricing services
or dealers using the mean of the bid and asked prices or, in the absence of
market quotations, at fair value based upon yield data relating to municipal
bonds with similar characteristics and general market conditions. Securities
which are not valued by independent pricing services or dealers are valued at
fair value using procedures established in good faith by the Board of Trustees.
Future contracts are valued at the settlement price established each day on the
exchange on which they are traded. Short-term securities with remaining
maturities of 60 days or less are valued at amortized cost, which approximates
market value.

B. SECURITY TRANSACTIONS Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis. The
Trust may purchase and sell securities on a "when-issued" or "delayed delivery"
basis with settlement to occur at a later date. The value of the security so
purchased is subject to market fluctuations during this period. The Trust will
segregate assets with its custodian having an aggregate value at least equal to
the amount of the when-issued or delayed delivery purchase commitments until
payment is made. At April 30, 2005, there were $11,796,988 of when-issued and
delayed delivery purchase commitments.

C. INVESTMENT INCOME Interest income is recorded on an accrual basis. Bond
premium is amortized and discount is accreted over the expected life of each
applicable security.

D. FEDERAL INCOME TAXES It is the Trust's policy to comply with the requirements
of Subchapter M of the Internal Revenue Code applicable to regulated investment
companies and to distribute substantially all of its taxable income to its
shareholders. Therefore, no provision for federal income taxes is required.

    The Trust intends to utilize provisions of the federal income tax laws which
allow it to carry a realized capital loss forward for eight years following the
year of the loss and offset such losses against any future realized capital
gains. At October 31, 2004, the Trust had an accumulated capital loss
carryforward for tax purposes of $303,797, which will expire on October 31,
2012.

</Table>

E. DISTRIBUTION OF INCOME AND GAINS The Trust declares and pays monthly
dividends from net investment income to common shareholders. Net realized gains,
if any, are distributed annually on a pro rata basis to common and preferred
shareholders. Distributions from net realized gains for book purposes may
include short-term capital gains and a portion of futures gains, which are
included as ordinary income for tax purposes.

    The tax character of distributions paid during the year ended October 31,
2004 was as follows:

<Table>

  Ordinary income...........................................  $    6,491

                                                              $1,652,706
                                                              ==========
</Table>

F. INSURANCE EXPENSE The Trust typically invests in insured bonds. Any portfolio
securities not specifically covered by a primary insurance policy are insured
either through secondary market insurance or portfolio insurance. The insurance
policies guarantee the timely payment of principal and interest on the
securities in the Trust's portfolio.

2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

Under the terms of the Trust's Investment Advisory Agreement, Van Kampen Asset
Management (the "Adviser") provides investment advice and facilities to the
Trust for an annual fee payable monthly of .55% of the average daily net assets
of the Trust

    For the six months ended April 30, 2005, the Trust recognized expenses of
approximately $5,100 representing legal services provided by Skadden, Arps,
Slate, Meagher & Flom LLP, of which a trustee of the Trust is a partner of such
firm and he and his law firm provide legal services as legal counsel to the
Trust.

    Under separate Accounting Services and Legal Services agreements, the
Adviser provides accounting and legal services to the Trust. The Adviser
allocates the cost of such services to each trust. For the six months ended
April 30, 2005, the Trust recognized expenses of approximately $21,500
representing Van Kampen's cost of providing accounting and legal services to the
Trust, which are reported as part of "Other" and "Legal" expenses, respectively,
on the Statement of Operations.

    Certain officers and trustees of the Trust are also officers and directors
of Van Kampen. The Trust does not compensate its officers or trustees who are
also officers of Van Kampen.

    The Trust provides deferred compensation and retirement plans for its
trustees who are not officers of Van Kampen. Under the deferred compensation
plan, trustees may elect to defer all or a portion of their compensation to a
later date. Benefits under the retirement

                                                                              23

plan are payable upon retirement for a ten-year period and are based upon each
trustee's years of service to the Trust. The maximum annual benefit per trustee
under the plan is $2,500.

3. INVESTMENT TRANSACTIONS

During the period, the cost of purchases and proceeds from sales of investments,
excluding short-term investments, were $53,163,215 and $40,937,069,
respectively.

4. DERIVATIVE FINANCIAL INSTRUMENTS

A derivative financial instrument in very general terms refers to a security
whose value is "derived" from the value of an underlying asset, reference rate,
or index.

    The Trust may invest up to 15% of its net assets in "inverse floating rate
obligations." The inverse floating rate obligations in which the Trust may
invest are typically created through a division of a fixed-rate municipal
obligation into two separate instruments, a short-term obligation and a
long-term obligation. The interest rate on the short-term obligation is set at
periodic auctions. The interest rate on the long-term obligation which the Trust
may purchase is the rate the issuer would have paid on the fixed-income
obligation, (i) plus the difference between such fixed rate and the rate on the
short-term obligation, if the short-term rate is lower than the fixed rate; or
(ii) minus such difference if the interest rate on the short-term obligation is
higher than the fixed rate. These securities have varying degrees of liquidity
and the market value of such securities generally will fluctuate in response to
changes in market rates of interest to a greater extent than the value of an
equal principal amount of a fixed rate security having similar credit quality,
redemption provisions and maturity. These securities tend to underperform the
market for fixed rate bonds in a rising interest rate environment, but tend to
outperform the market for fixed rate bonds when interest rates decline or remain
relatively stable. Although volatile, inverse floating rate obligations
typically offer the potential for yields exceeding the yields available on fixed
rate bonds with comparable credit quality, coupon, call provisions and maturity.
These securities usually permit the investor to convert the floating rate
security counterpart to a fixed rate (normally adjusted downward), and this
optional conversion feature may provide a partial hedge against rising rates if
exercised at an opportune time.

    In order to seek to manage the interest rate exposure of the Trust's
portfolio in a changing interest rate environment, the Trust may purchase or
sell financial futures contracts or engage in transactions involving interest
rate swaps, caps, floors or collars. The Trust expects to enter into these
transactions primarily as a hedge against anticipated interest rate or fixed
income market changes, for duration management or for risk management purposes,
but may also enter into these transactions to generate additional income. All of
the Trust's portfolio holdings, including derivative instruments, are marked to
market each day with the change in value reflected in unrealized
appreciation/depreciation. Upon disposition, a realized gain or loss is
recognized accordingly, except when taking delivery of a security underlying a
futures contract. In this instance, the recognition of gain or loss is postponed
until the disposal of the security underlying the future contract.

    During the period, the Trust invested in futures contracts, a type of
derivative. A futures contract is an arrangement involving the delivery of a
particular asset on a specified future date at an agreed upon price. The Trust
generally invests in exchange traded futures on U.S. Treasury Bonds and Notes
and typically closes the contract prior to the delivery date.

VAN KAMPEN TRUST FOR INSURED MUNICIPALS

NOTES TO FINANCIAL STATEMENTS -- APRIL 30, 2005 (UNAUDITED) continued

Upon entering into futures contracts, the Trust maintains an amount of cash or
liquid securities with a value equal to a percentage of the contract amount with
either a futures commission merchant pursuant to the rules and regulations
promulgated under the Investment Company Act of 1940, as amended, or with its
custodian in an account in the broker's name. This amount is known as initial
margin. During the period the futures contract is open, payments are received
from or made to the broker based upon changes in the value of the contract (the
variation margin). The risk of loss associated with a futures contract is in
excess of the variation margin reflected on the Statement of Assets and
Liabilities.

    Transaction in futures contracts for the six months ended April 30, 2005,
were as follows:

5. PREFERRED SHARES

The Trust has outstanding 3,600 Auction Preferred Shares ("APS") in two series
of 1,800 shares each. Dividends are cumulative and the dividend rate is
generally reset every 28 days for both series through an auction process. The
average rate in effect on April 30, 2005 was 2.770%. During the six months ended
April 30, 2005, the rates ranged from 1.400% to 2.850%.

    The Trust pays annual fees equivalent to .25% of the preferred share
liquidation value for the remarketing efforts associated with the preferred
auctions. These fees are included as a component of "Preferred Share
Maintenance" expense on the Statement of Operations.

    The APS are redeemable at the option of the Trust in whole or in part at the
liquidation value of $25,000 per share plus accumulated and unpaid dividends.
The Trust is subject to certain asset coverage tests and the APS are subject to
mandatory redemption if the tests are not met.

                                                                              25
