TIMOTHY D. HANEY, PORTFOLIO MANAGER, HAS MANAGED THE TRUST SINCE 1996 AND HAS WORKED IN THE INVESTMENT INDUSTRY SINCE 1988. THE FOLLOWING DISCUSSION REFLECTS HIS VIEWS ON THE TRUST'S PERFORMANCE. Q WHAT WAS THE MARKET ENVIRONMENT OF THE PAST SIX MONTHS, AND HOW DID THE TRUST PERFORM IN THAT ENVIRONMENT? A The environment over the past six months has been defined by two major themes. The first of these was the level of interest rates. The period began with interest rates at levels not seen in over three decades and, surprisingly for many, ended with rates slightly lower. The Federal Reserve Board (the Fed) helped keep rates low with a widely anticipated rate cut in November, driven by economic uncertainty and geopolitical risk. The low level of rates led to a boom in issuance by municipalities seeking to lock in low financing costs. As a result, issuance reached a record level of $354 billion in 2002 and continued to be exceptional in the first quarter of 2003. The other theme in the market during the period was the relative attractiveness of municipal bonds, which produced enough demand to absorb the record issuance. Investors, wary of volatility in the equity market and in the geopolitical arena, flocked to perceived safe haven investments. Their risk aversion counteracted growing expectations for economic recovery and rising interest rates and was a key factor in keeping interest rates at historically low levels. In their ongoing preference for low-risk assets, investors bid Treasury prices up to such high levels that municipal bonds became as attractively valued as they have ever been relative to Treasuries. Insurance companies also moved heavily into municipal bonds as their mainstay corporate bond holdings became less attractive. At the same time, issuers recognized investor concerns over economic weakness by insuring roughly 50 percent of all issuance. This credit enhancement made municipal bonds even more attractive to risk-averse investors. While lower financing costs were a boon to municipal issuers, the continuing weakness in the economy had a negative impact on municipal credit quality, particularly in the first quarter of 2003. Moody's upgrades barely exceeded the number of downgrades in the first quarter with 4 credit quality facing continued pressure from rising social service costs and weak national and regional economic conditions. As a result, municipalities face enormous deficits in 2003, when their combined shortfall is expected to reach $90 billion. Performance along the yield curve was varied. The Fed's November rate cut fueled a rally in short-term bonds that helped pull yields lower at the front end of the curve. Despite that rally, the best performing segment of the curve was the long-intermediate portion where performance was largely driven by buying activity among institutional investors drawn to the bonds' attractive total return potential. The trust's monthly dividend of $0.0825 per share translated to a distribution rate of 7.12 percent based on the trust's closing common share market price on April 30, 2003. Based on these figures, investors would have to earn a distribution rate of 11.60 percent on a taxable investment (for an investor in the 38.60 percent federal income tax bracket) to match the tax-exempt yield provided by the trust. For the six months through April 30, 2003, the trust produced a total return of 5.46 percent based on common share market price. By comparison, the Lehman Brothers Municipal Bond Index posted a total return of 3.59 percent for the same period. Of course, past performance is no guarantee of future results. Investment return, common share market price and net asset value will fluctuate and trust shares, when sold, may be worth more or less than their original cost. 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. The Lehman Brothers Municipal Bond Index is an unmanaged, broad-based statistical composite of municipal bonds. Index returns do not include any sales charges or fees that would be paid by an investor purchasing the securities the index represents. Such costs would lower performance. It is not possible to invest directly in an index. For additional information, please refer to the performance summary section. Q WHAT STRATEGIES DID YOU PURSUE IN MANAGING THE TRUST? A With interest rates hovering near record lows, we focused on protecting the trust from the potential adverse effects of rising interest rates, while maintaining the trust's yield. One of our primary methods for trying to do this was to purchase premium bonds with maturities of between 15 and 20 years, priced to a ten-year call date. Our quantitative analysis showed that this segment of the yield curve offered a favorable combination of total return potential and downside protection. The yield of these bonds is competitive, corresponding to their 15 to 20 year maturity dates, yet their interest rate volatility is more closely related to the 10-year call feature. We funded our purchases in this maturity range chiefly through sales of bonds in the 10- and 30-year segments of the yield curve. This alteration of the trust's yield curve exposure should be beneficial if rates 5 rise on the short end of the yield curve. Our preference for long-intermediate bonds led to several shifts in the portfolio's sector composition, though these were generally not reflective of strong sector views so much as the availability of bonds at key points on the yield curve. The strategy of shifting assets along the curve resulted in declines in the airport sector (down by 2.1 percent), transportation (down 1.6 percent), and public education (down 1.5 percent). In turn, portfolio holdings in retail electric/gas bonds were up by 2.9 percent and general purpose bonds exposure rose by 2.5 percent. The generally poor economies of the states and municipalities also led us to upgrade the portfolio's overall credit profile. The ongoing economic difficulties across the country have made uninsured and lower-quality paper increasingly unattractive in our analysis, and as a result we focused our purchases on higher-quality paper. During the period, the trust's exposure to AAA rated bonds climbed by 4.1 percent. One of the sectors we avoided during the period was tobacco bonds. These bonds were issued by states seeking to securitize their future income streams resulting from settlements from class action suits against the major tobacco companies. Recent litigation in Illinois resulted in a judge awarding billions more in a suit alleging that the companies misled smokers about the amount of nicotine in "light" cigarettes. In order to appeal, the law required the companies to put up such substantial amounts of money that some began talking about potential bankruptcy, and the tobacco bonds' credit ratings and price performance suffered accordingly. Our decision not to invest in these securities was a benefit to shareholders during the period. 6 BY THE NUMBERS YOUR TRUST'S INVESTMENTS April 30, 2003 (Unaudited) THE FOLLOWING PAGES DETAIL YOUR

SIGNIFICANT ACCOUNTING POLICIES Van Kampen Strategic Sector Municipal Trust (the "Trust") is registered as a non-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 tax, consistent with preservation of capital. The Trust will invest in a portfolio consisting substantially of municipal obligations from those market sectors which the Adviser feels will best meet the Trust's investment objective. The Trust commenced investment operations on January 22, 1993. 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. 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 maintain, in a segregated account with its custodian, assets 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, 2003, there was $3,167,445 of when-issued or 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. 21 NOTES TO FINANCIAL STATEMENTS April 30, 2003 (Unaudited) 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, 2002, the Trust had an accumulated capital loss carryforward for tax purposes of $9,475,367 which will expire between October 31, 2003 and October 31, 2008. Of this amount, $6,109,988 will expire on October 31, 2003. At April 30, 2003 the cost and related gross unrealized appreciation and depreciation are as follows: <Table> Cost of investments for tax purposes........................ $235,039,683 ============ Gross tax unrealized appreciation........................... $ 21,494,056 Gross tax unrealized depreciation........................... (3,748,562) ------------ Net tax unrealized appreciation on investments.............. $ 17,745,494 ============ </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, which are included as ordinary income for tax purposes. The tax character of distributions paid during the year ended October 31, 2002 was as follows: <Table> <Caption> 2002 Distributions paid from: Ordinary Income........................................... $424,794 Long-Term capital gain.................................... -0- -------- $424,794 ======== </Table> As of October 31, 2002, the components of distributable earnings on a tax basis were as follows: <Table> Undistributed ordinary income............................... $41,137 </Table> 22 NOTES TO FINANCIAL STATEMENTS April 30, 2003 (Unaudited) 2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES Under the terms of the Trust's Investment Advisory Agreement, Van Kampen Investment Advisory Corp. (the "Adviser") will provide investment advice and facilities to the Trust for an annual fee payable monthly of .65% of the average daily net assets of the Trust. In addition, the Trust will pay a monthly administrative fee to Van Kampen Investments Inc. or its affiliates' (collectively "Van Kampen"), the Trust's Administrator, at an annual rate of ..10% of the average daily net assets of the Trust. The administrative services provided by the Administrator include record keeping and reporting responsibilities with respect to the Trust's portfolio and preferred shares and providing certain services to shareholders. For the six months ended April 30, 2003, the Trust recognized expenses of approximately $6,600 representing legal services provided by Skadden, Arps, Slate, Meagher & Flom (Illinois), 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, 2003, the Trust recognized expenses of approximately $18,500 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, in 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 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 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 $32,818,434 and $30,407,728, 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. 23 NOTES TO FINANCIAL STATEMENTS April 30, 2003 (Unaudited) 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. 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 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).

Dividends are cumulative and the dividend rate for both Series is generally reset every 28 days through an auction process. At April 30, 2003, the average rate in effect was 1.097%. During the six months ended April 30, 2003, the rates ranged from 0.990% to 1.800%.

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 BOARD OF TRUSTEES AND IMPORTANT ADDRESSES VAN KAMPEN STRATEGIC SECTOR MUNICIPAL TRUST BOARD OF TRUSTEES DAVID C.
