As a result of recent market activity, current performance may vary from the figures shown. For more up-to-date information, please visit vankampen.com or speak with your financial advisor. 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 is unmanaged and does not include any sales charges or fees. Such costs would lower performance.

MARKET CONDITIONS The state of the U.S. economy remained mixed over the six-month period under review. On the positive side, economic growth continued to be robust, with Gross Domestic Product growth topping 4 percent in both the last quarter of 2003 and, preliminarily, the first quarter of this year. While this strength in output has historically triggered fears of rising interest rates, yields remained stubbornly low across the municipal curve. These low yields were partly the result of the continued low levels of observed inflation in the U.S. economy. Unfortunately, they also reflected continuing weakness in the job market, which remained soft throughout most of the period. The soft job numbers, coupled with persistently low inflation, led the Federal Open Market Committee (the Fed) to maintain its accommodative stance throughout the period. The surprisingly rapid job growth data released in April, coupled with rapidly rising commodity and high oil prices, led many investors to fear that the Fed would be forced to raise interest rates earlier than the market initially expected. As a result, bond yields across all major sectors spiked in April. Supply of new municipal bonds in calendar 2003 hit record levels as municipalities moved to take advantage of historically low interest rates. Many cities and states sought to reduce expenditures by refinancing existing debt and replacing it with lower-yielding bonds. In other cases, municipalities attempted to meet current and future funding needs by issuing new debt. This activity slowed in the first months of 2004. The low interest rates that prevailed over much of the period also had an impact on the demand for municipal bonds. Retail and institutional investor activity slowed as holders of municipal bonds saw little reason to sell bonds purchased at higher yield levels and reinvest at lower yields. However, the period was marked by rising activity among non-traditional investors, such as hedge funds and insurance companies seeking to take advantage of the attractiveness of municipal bonds relative to some taxable securities. Additionally, investors' search for yield led to significant outperformance by lower-rated bonds with greater credit risk. Sectors such as health care, with a preponderance of lower-rated issues, performed particularly well. (1)Team members may change without notice at any time. 2 PERFORMANCE ANALYSIS Closed-end fund returns 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 significantly. On an NAV basis, the trust outperformed its benchmark, the Lehman Brothers Municipal Bond Index, but underperformed on a market-price basis. (See table below.) 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 typically reinvested in longer-term securities, taking advantage of the difference between short- and longer-term rates. As yields rose during the period, the prices of bonds declined. The trust's use of leverage magnified this negative movement. However, the portfolio saw strong relative performance from its higher-yielding holdings during the period, which counterbalanced the effects of the leverage and helped produce a total return at NAV slightly higher than that of the benchmark, which is not leveraged. Our analysis of the macroeconomic environment, coupled with the levels of interest rates near multi-decade lows, led us to believe that interest rates were more likely to rise than to fall further. As a result, we kept the trust's duration (a measure of interest-rate sensitivity) below that of its benchmark in order to limit the potentially damaging impact of any increase in interest rates. This approach hampered the trust's returns for much of the period as interest rates fell; however, it helped buoy returns when interest rates soared in the final weeks of the period. The trust's performance was also modestly hampered by its bias, relative to the benchmark, toward high-quality securities. Municipal-bond investors during the period responded to the improving economy by reducing the yield spreads between higher- and lower-rated bonds (yield spreads reflect the premium demanded by investors to buy lower-rated bonds). As a result, lower-quality bonds outperformed. The portfolio had a 77 percent exposure to bonds rated AA/Aa or higher at the end of the period.

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. 3 We adjusted the portfolio's term structure in anticipation of rising interest rates. Our research showed that the intermediate portion of the curve offered the most promising total-return potential. As a result, we focused our purchases on the 14- to 19-year segment of the curve. Many of the securities we identified had the added appeal of premium coupons and 10-year call dates, which served to add income to the portfolio while limiting its interest-rate exposure. Our trading activity during the period was well below traditional norms because we wanted to avoid having to reinvest into securities with low yields. That said, we were able to make selective relative-value trades among securities and sectors as they moved into and out of fair value. Some of these acquisitions were funded by the proceeds of housing bonds that were called away by their issuers during the period. In other cases we sold bonds that met their performance objectives. We reinvested this cash into securities with more promising total-return characteristics. The trust's portfolio remained well diversified during the period, with its holdings spread across many major municipal-bond sectors. We believe this long-standing strategy helps to minimize the risk of over-concentration in any single sector, while also giving the portfolio exposure to as many potential sources of return as possible. The three largest sector exposures at the end of the period were general purpose, public building and public education. The trust also benefited from its holdings of United Airline-backed securities, which appreciated strongly during the period. As mentioned above, the portfolio's below-market duration served it well in the final weeks of the period, when interest rates rose sharply. While it is impossible to predict how long this trend will hold, we believe that the trust is well positioned to weather further increases in rates.

SIGNIFICANT ACCOUNTING POLICIES Van Kampen Investment Grade Municipal Trust (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. The Trust will normally invest at least 80% of its total assets in tax-exempt municipal securities rated investment grade at the time of investment. The Trust commenced investment operations on November 30, 1989. Effective November 30, 2003, the Trust's investment adviser, Van Kampen Investment Advisory Corp. merged into its affiliate, Van Kampen Asset Management. 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 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, 2004, the Trust had $982,590 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 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, 2003, the Trust had an 18 VAN KAMPEN INVESTMENT GRADE MUNICIPAL TRUST NOTES TO FINANCIAL STATEMENTS -- APRIL 30, 2004 (UNAUDITED) continued accumulated capital loss carryforward for tax purposes of $3,897,092, which will expire between October 31, 2005 and October 31, 2010. At April 30, 2004, the cost and related gross unrealized appreciation and depreciation are as follows: <Table> Cost of investments for tax purposes........................ $72,315,567 =========== Gross tax unrealized appreciation........................... $ 3,898,482 Gross tax unrealized depreciation........................... (2,602,788) ----------- Net tax unrealized appreciation on investments.............. $ 1,295,694 =========== </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. 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, 2003 was as follows: <Table> Distributions paid from: Ordinary income........................................... $3,083 Long-term capital gain.................................... -0- ------ $3,083 ====== </Table> As of October 31, 2003, the components of distributable earnings on a tax basis were as follows: <Table> Undistributed ordinary income............................... $15,735 </Table> Net realized gains or losses differ for financial and tax reporting purposes primarily as a result of the capitalization of reorganization and restructuring costs for tax purposes. 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 .60% of the average daily net assets of the Trust. In addition, the Trust pays a monthly administrative fee to Van Kampen Investments Inc. or its affiliates (collectively "Van Kampen"), the Trust's Administrator, at an annual rate of .05% of the average daily net assets of the Trust. Effective June 1, 2004, the administrative fee was reduced from ..05% to .00%. For the six months ended April 30, 2004, the Trust recognized expenses of approximately $2,000 representing legal services provided by Skadden, Arps, Slate, Meagher & Flom LLP, counsel to the Trust, of which a trustee of the Trust is an affiliated person. 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, 2004, the Trust recognized expenses of approximately $12,000 representing Van Kampen Investments Inc.'s or its affiliates' 19 VAN KAMPEN INVESTMENT GRADE MUNICIPAL TRUST NOTES TO FINANCIAL STATEMENTS -- APRIL 30, 2004 (UNAUDITED) continued (collectively "Van Kampen") cost of providing accounting and legal services to the Trust, which are reported as part of "Other" and "Legal" expenses, respectively, in the Statement of Operations.

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 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. During the period, the Trust owned shares of the following affiliated companies. Affiliated companies are defined by the Investment Company Act of 1940, as amended, as those companies in which a fund holds 5% or more of the outstanding voting securities. <Table> <Caption> REALIZED INTEREST MARKET VALUE NAME PAR GAIN/(LOSS) INCOME 4/30/04 COST Dogwood Addition PRD Muni Ppty Owners Multi-Purp Dist No 8 Maumelle AK Impt Ser 2001 Rfdg.................. $ 425,960 $0 $20,736 $421,832 $ 425,960 Sun N Lake of Sebring, FL Impt Dist Spl Assmt........ 242,942 0 0 0 242,942 Sun N Lake of Sebring, FL Impt Dist Spl Assmt........ 225,000 0 0 0 224,243 Sun N Lake of Sebring, FL Impt Dist Spl Assmt Ser A.......................... 2,300,000 0 0 616,400 2,300,000 </Table> 3. INVESTMENT TRANSACTIONS During the period, the cost of purchases and proceeds from sales of investments, excluding short-term investments, were $8,741,237 and $7,592,694, 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 the 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. Risks may arise as a result of the potential inability of the counterparties to meet the terms of their contracts. 20 VAN KAMPEN INVESTMENT GRADE MUNICIPAL TRUST NOTES TO FINANCIAL STATEMENTS -- APRIL 30, 2004 (UNAUDITED) continued During the period, the Trust invested in futures contracts, a type of derivative. A futures contract is an agreement 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 delivery date. 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 future commission merchant pursuant to 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. Transactions in futures contracts, each with a par value of $100,000, for the six months ended April 30, 2004, were as follows: <Table> <Caption> CONTRACTS Outstanding at October 31, 2003............................. 62 Futures Opened.............................................. 184 Futures Closed..............................................

PREFERRED SHARES The Trust has outstanding 250 Remarketed Preferred Shares ("RP"). Dividends are cumulative and the dividend rate is currently reset every 28 days through a remarketing process. The rate in effect on April 30, 2004 was 0.97%. During the six months ended April 30, 2004, the rates ranged from 0.923% to 1.120%. The Trust pays annual fees equivalent to .25% of the preferred share liquidation value for the remarketing efforts associated with the preferred shares. These fees are included as a component of "Preferred Share Maintenance" expense in the Statement of Operations. The RP are redeemable at the option of the Trust in whole or in part at the liquidation value of $100,000 per share plus accumulated and unpaid dividends. The Trust is subject to certain asset coverage tests and the RP are subject to mandatory redemption if the tests are not met. 21 VAN KAMPEN INVESTMENT GRADE MUNICIPAL TRUST 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, State Street Bank and Trust Company, 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 22 VAN KAMPEN INVESTMENT GRADE MUNICIPAL TRUST 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 change 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 State Street Bank and Trust Company, P.O. Box 8200, Boston, MA 02266-8200. 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: Van Kampen Funds Inc.
