PERFORMANCE DATA QUOTED REPRESENTS PAST PERFORMANCE, WHICH IS NO GUARANTEE OF
FUTURE RESULTS, AND CURRENT PERFORMANCE MAY BE LOWER OR HIGHER THAN THE FIGURES
SHOWN. FOR THE MOST RECENT MONTH-END PERFORMANCE FIGURES, PLEASE VISIT
VANKAMPEN.COM OR SPEAK WITH YOUR FINANCIAL ADVISOR. INVESTMENT RETURNS, NET
ASSET VALUE (NAV) AND COMMON SHARE MARKET PRICE WILL FLUCTUATE AND TRUST SHARES,
WHEN SOLD, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST.

NAV per share is determined by dividing the value of the trust's portfolio
securities, cash and other assets, less all liabilities and preferred shares, 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 SIX-MONTH PERIOD ENDED APRIL 30, 2006

MARKET CONDITIONS

The economy continued to grow during the six-month period ended April 30, 2006,
demonstrating some resiliency in the face of rising oil and other commodity
prices, the Gulf Coast hurricanes, and emerging weakness in the housing market.
This expansion was more modest in the final months of 2005, but gained
considerable momentum in the first quarter.

Against the backdrop of growth and good employment data, the Federal Open Market
Committee (the "Fed") continued raising the federal funds target rate during the
period, implementing four additional increases of 25 basis points each. These
moves brought the target rate to 4.75 percent. The final hike of the period
represented the fifteenth consecutive increase--the longest stretch of increases
in 25 years. As the period came to a close, market observers speculated about
the Fed's near-term intentions, given the central bank's view that although
longer-term inflation currently appeared contained, commodity prices could
amplify inflationary pressures.

Returns across the municipal bond market varied significantly. As investors
sought income opportunities, lower rated bonds outpaced investment-grade bonds
by a wide margin. Long-term bonds earned the best returns, broadly speaking,
while bonds in the three-to-seven year range posted the most muted gains.

Municipal bond issuance was robust during the final months of 2005. (In fact,
2005 marked a record high for municipal bond volume.) The tide changed in 2006,
however. As rising rates discouraged issuers from refinancing debt, national
municipal issuance dropped by approximately 25 percent in the first four months
of the year versus the same period in 2005. While supply ebbed, the market's
appetite for municipal bonds remained strong, with particularly heavy demand
from high yield municipal bond funds.

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 and preferred shares, 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 both an NAV basis and on a market price basis, the trust outperformed
its benchmark index, the Lehman Brothers Municipal Bond Index.

Performance data quoted represents past performance, which is no guarantee of
future results, and current performance may be lower or higher than the figures
shown. Investment return, net asset value and common share market price will
fluctuate and trust shares, when sold, may be worth more or less than their
original cost. See Performance Summary for additional performance information
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, which reduced the benefits of the trust's leverage activities.

We managed the trust according to our long-standing "relative value" discipline.
Our strategy involved buying bonds when our research indicates they are
attractively valued, and then selling them when they reached our return targets.
We then invested the proceeds into bonds which we believe offered greater future
total return prospects. We used rigorous research to seek fundamentally strong
issues with high liquidity. (Liquid securities are those for which there is a
robust market of purchasers and sellers.)

The trust invests in insured securities, with most bonds holding a credit rating
of AAA. Throughout the period, we followed a variety of strategies to pursue
yield within the parameters of our quality-driven approach.

We positioned the portfolio to reflect our view that yields would continue to
rise, with the yields of short-term bonds rising more rapidly than those of
long-term bonds. Reflecting this analysis, we kept the trust's duration shorter
than that of its benchmark; and this strategy served the trust well. (Duration
is a measure of interest rate sensitivity.)

                                                                               3


The trust also benefited from our view that the long-term segment of the yield
curve was most compelling. We sold shorter-maturity bonds that were pre-
refunded, capturing appreciation gains. We redeployed these assets, along with
proceeds from bonds that were called by their issuers, into longer-term bonds.
In our purchases, we generally selected bonds with maturities of 25 to 30 years,
and favored issues with premium coupons and defensive characteristics. In
contrast, we avoided non-callable bonds and zero-coupon bonds, as these tend to
underperform during periods of rising interest rates.

Although the supply of insured issuance dropped dramatically in 2006, we
maintained a well-diversified portfolio, with a bias to the essential services
sector of the market that proved advantageous. As of the close of the period,
the trust's largest sector weightings were in the airports, public education and
general purpose sectors. Overall, the trust's preference for well-known issues
with strong demand from in-state investors enhanced performance as well.

We also found attractive yield opportunities by diversifying the portfolio to
include securities insured by less well-known, but financially sound companies
with AAA ratings. These bonds often offered higher yields than comparable issues
insured by more recognized companies.

A small stake in inverse floating rate securities, representing 2.4 percent of
assets at the close of the period, provided an additional boost to performance.

VIM's procedure for reinvesting all dividends and distributions in common shares
is through purchases in the open market. This method helps support the market
value of the Fund's shares. In addition, we would like to remind you that the
Trustees have approved a procedure whereby the Fund 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, whichever is lower at the time
of purchase.

There is no guarantee that any sectors mentioned will continue to perform as
discussed herein or that securities in such sectors will be held by the trust in
the future.

VAN KAMPEN TRUST FOR INSURED MUNICIPALS

NOTES TO FINANCIAL STATEMENTS -- APRIL 30, 2006 (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 (the "1940 Act"), as amended. The Trust's investment
objective is to seek to provide a high level of current income exempt from
federal income taxes, 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.
Futures 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 the 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, 2006, the Trust had no 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. During the prior fiscal year, the Trust utilized capital losses carried
forward of $303,797.

                                                                              21

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

included as ordinary income for tax purposes.

    The tax character of distributions paid during the year ended October 31,
2005 was as follows:

</Table>

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, 2006, the Trust recognized expenses of
approximately $6,900 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 Legal Services, Accounting Services and Chief Compliance
Officer (CCO) Employment agreements, the Adviser provides accounting and legal
services and the CCO provides compliance services to the Trust. The costs of
these services are allocated to each trust. For the six months ended April 30,
2006, the Trust recognized expenses of approximately $27,700, representing Van
Kampen Investments Inc.'s or its affiliates' (collectively "Van Kampen") cost of
providing accounting and legal services to the Trust, as well as, the salary,
benefits and related costs of the CCO and related support staff paid by Van
Kampen. Services provided pursuant to the Legal Services agreement are reported
as part of "Legal" expenses on the Statement of Operations. Services provided
pursuant to the Accounting Services and CCO Employment agreement are reported as
part of "Other" expenses 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

 22


VAN KAMPEN TRUST FOR INSURED MUNICIPALS

NOTES TO FINANCIAL STATEMENTS -- APRIL 30, 2006 (UNAUDITED) continued

defer all or a portion of their compensation to a later date. Benefits under the
retirement 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 $37,612,840 and $41,105,206,
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.

    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 futures contract.

    Summarized below are the specific types of derivative financial instruments
used by the Trust.

A. FUTURES CONTRACTS 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 contracts on U.S. Treasury
securities and typically closes the contract prior to the delivery date. These
contracts are generally used to manage the Trust's effective maturity and
duration. 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 1940 Act, 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, 2006,
were as follows:

NOTES TO FINANCIAL STATEMENTS -- APRIL 30, 2006 (UNAUDITED) continued

B. INDEXED SECURITY An inverse floating rate security is one where the coupon is
inversely indexed to a short-term floating interest rate multiplied by a
specific factor. As the floating rate rises, the coupon is reduced. Conversely,
as the floating rate declines, the coupon is increased. The price of these
securities may be more volatile than the price of a comparable fixed rate
security. These instruments are typically used by the Trust to enhance the yield
of the portfolio. These instruments are identified in the portfolio of
investments.

C. INTEREST RATE SWAPS The Trust may enter into interest rate swaps primarily to
preserve a return or spread on a particular investment or portion of its
portfolio, as a duration management technique or to protect against any increase
in the price of securities the Trust anticipates purchasing at a later date.
Interest rate swaps are contractual agreements to exchange periodic interest
payment streams calculated on a predetermined notional principal amount.
Interest rate swaps generally involve one party paying a fixed interest rate and
the other party paying a variable rate. The Trust will usually enter into swaps
on a net basis, i.e, the two payment streams are netted out in a cash settlement
on the payment date or dates specified in the instrument, with the Trust
receiving or paying, as the case may be, only the net amount of the two
payments. The Trust accrues the net amount with respect to each swap on a daily
basis. This net amount is recorded within unrealized appreciation/ depreciation
on swap contracts. Upon cash settlement of the periodic payments, the net amount
is recorded as realized gain/loss on swap contracts on the Statement of
Operations. Risks may arise as a result of the potential inability of the
counterparties to meet the terms of their contracts. If there is a default by
the counterparty, the Trust will have contractual remedies pursuant to the
agreements related to the transaction.

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, 2006 was 3.595%. During the six months ended April 30,
2006, the rates ranged from 2.590% to 4.500%.

    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.

6. INDEMNIFICATIONS

The Trust enters into contracts that contain a variety of indemnifications. The
Trust's maximum exposure under these arrangements is unknown. However, the Trust
has not had prior claims or losses pursuant to these contracts and expects the
risk of loss to be remote.

VAN KAMPEN TRUST FOR INSURED MUNICIPALS

DIVIDEND REINVESTMENT PLAN

    The Trust offers a dividend reinvestment plan (the "Plan") pursuant to which
Common Shareholders may elect to have dividends and capital gains distributions
reinvested in Common Shares of the Trust. The Trust declares dividends out of
net investment income, and will distribute annually net realized capital gains,
if any. Common Shareholders may join or withdraw from the Plan at any time.

    If you decide to participate in the Plan, EquiServe Trust Company, N.A., as
your Plan Agent, will automatically invest your dividends and capital gains
distributions in Common Shares of the Trust for your account.

HOW TO PARTICIPATE

    If you wish to participate and your shares are held in your own name, call
1-800-341-2929 for more information and a Plan brochure. If your shares are held
in the name of a brokerage firm, bank, or other nominee, you should contact your
nominee to see if it would participate in the Plan on your behalf. If you wish
to participate in the Plan, but your brokerage firm, bank or nominee is unable
to participate on your behalf, you should request that your shares be
re-registered in your own name which will enable your participation in the Plan.

HOW THE PLAN WORKS

    Participants in the Plan will receive the equivalent in Common Shares valued
on the valuation date, generally at the lower of market price or net asset
value, except as specified below. The valuation date will be the dividend or
distribution payment date or, if that date is not a trading day on the national
securities exchange or market system on which the Common Shares are listed for
trading, the next preceding trading day. If the market price per Common Share on
the valuation date equals or exceeds net asset value per Common Share on that
date, the Trust will issue new Common Shares to participants valued at the
higher of net asset value or 95% of the market price on the valuation date. In
the foregoing situation, the Trust will not issue Common Shares under the Plan
below net asset value. If net asset value per Common Share on the valuation date
exceeds the market price per Common Share on that date, or if the Board of
Trustees should declare a dividend or capital gains distribution payable to the
Common Shareholders only in cash, participants in the Plan will be deemed to
have elected to receive Common Shares from the Trust valued at the market price
on that date. Accordingly, in this circumstance, the Plan Agent will, as agent
for the participants, buy the Trust's Common Shares in the open market for the
participants' accounts on or shortly after the payment date. If, before the Plan
Agent has completed its purchases, the market price exceeds the net asset value
per share of the Common Shares, the average per share purchase price paid by the
Plan Agent may exceed the net asset value

                                                                              25

VAN KAMPEN TRUST FOR INSURED MUNICIPALS

DIVIDEND REINVESTMENT PLAN continued

of the Trust's Common Shares, resulting in the acquisition of fewer Common
Shares than if the dividend or distribution had been paid in Common Shares
issued by the Trust. All reinvestments are in full and fractional Common Shares
and are carried to three decimal places.

    Experience under the Plan may indicate that changes are desirable.
Accordingly, the Trust reserves the right to amend or terminate the Plan as
applied to any dividend or distribution paid subsequent to written notice of the
changes sent to all Common Shareholders of the Trust at least 90 days before the
record date for the dividend or distribution. The Plan also may be amended or
terminated by the Plan Agent by at least 90 days written notice to all Common
Shareholders of the Trust.

COSTS OF THE PLAN

    The Plan Agent's fees for the handling of the reinvestment of dividends and
distributions will be paid by the Trust. However, each participant will pay a
pro rata share of brokerage commissions incurred with respect to the Plan
Agent's open market purchases in connection with the reinvestment of dividends
and distributions. No other charges will be made to participants for reinvesting
dividends or capital gains distributions, except for certain brokerage
commissions, as described above.

TAX IMPLICATIONS

    You will receive tax information annually for your personal records and to
help you prepare your federal income tax return. The automatic reinvestment of
dividends and capital gains distributions does not relieve you of any income tax
which may be payable on dividends or distributions.

RIGHT TO WITHDRAW

    Plan participants may withdraw at any time by calling 1-800-341-2929 or by
writing EquiServe Trust Company, N.A., c/o Computershare Investor Services, P.O.
Box 43010, Providence, Rhode Island 02940-3010. If you withdraw, you will
receive, without charge, a share certificate issued in your name for all full
Common Shares credited to your account under the Plan and a cash payment will be
made for any fractional Common Share credited to your account under the Plan.
You may again elect to participate in the Plan at any time by calling
1-800-341-2929 or writing to the Trust at:
