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.

Trust Report

FOR THE 6-MONTH PERIOD ENDED APRIL 30, 2005

Van Kampen California Quality Municipal Trust 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.

From a credit perspective, the state of California has made some positive
strides. The California government's measures to stem current and projected
budget deficits have been met with broad approval by investors. This in turn has
resulted in improved demand for California bonds and a general rise in bond
prices. However, the state faces notable challenges to achieving fiscal balance.
For example, the governor's declining popularity could hinder his plans for
resolving the state's deficit.

During the period, the state maintained its position as the leading issuer of
new municipal debt. More than half of the new issuance which came to market was
protected by credit insurance, which was helpful for us as we attempted to put
cash to work.

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 California
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. We remained focused on
keeping the portfolio's credit quality high. Almost seventy percent of the bonds
in the portfolio were rated AAA at the close of the period. However, we also
took advantage of what we believed to be compelling opportunities to add
higher-coupon securities when our analyst identified securities with attractive
structures and yield characteristics. By the end of the period, bonds rated BBB
represented 13 percent of the portfolio. We also added unrated securities in

                                                                               3


cases where our rigorous internal analysis indicated credit strength comparable
to BBB rated securities. This unrated portion totaled 11 percent as of the close
of the reporting period. These allocations to lower rated and unrated securities
proved beneficial as the market favored higher-coupon securities.

Our purchases during the period 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. As part of this strategy, we also kept the
trust's duration (a measure of interest rate sensitivity) below that of the
market.

The portfolio remained well diversified across the major sectors of the
California municipal market. We continued to favor the essential services
segments of the market, while avoiding the housing sector out of concerns about
those bonds' structural characteristics. We remained especially selective
regarding the health care sector, and continued to avoid tobacco bonds. We also
avoided zero coupon bonds. Tax districts, public building and public education
represented the portfolio's top exposures.

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

(c) These securities are restricted and may be resold only in transactions
    exempt from registration which are normally those transactions with
    qualified institutional buyers. Restricted securities comprise 1.9% of net
    assets applicable to common shares.

(d) Security is a "step-up" bond where the coupon increases or steps up at a
    predetermined date.

(e) 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. 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.

(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 by .01%. Per share, ratios and
   supplemental data for the 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.

VAN KAMPEN CALIFORNIA QUALITY MUNICIPAL TRUST

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

1. SIGNIFICANT ACCOUNTING POLICIES

Van Kampen California Quality 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 and California income taxes
consistent with preservation of capital. The Trust will invest in a portfolio
consisting substantially of California municipal obligations rated investment
grade at the time of investment, but may invest up to 20% of its assets in
unrated securities which are believed to be of comparable quality to those rated
investment grade. The Trust commenced investment operations on September 27,
1991.

    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
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, 2005, the Trust had $1,996,800 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.

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.

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,

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. Effective November 1, 2004, the investment advisory fee was
reduced from .60% to .55%.

    For the six months ended April 30, 2005, the Trust recognized expenses of
approximately $4,600 representing legal services provided by Skadden, Arps,
Slate, Meagher & Flom LLP, counsel to the Trust, 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 $20,200
representing Van Kampen Investments Inc.'s or its affiliates' (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.

    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.

                                                                              19


VAN KAMPEN CALIFORNIA QUALITY MUNICIPAL TRUST

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

    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 $34,200,455 and $34,042,161,
respectively.

4. PREFERRED SHARES

The Trust has outstanding 3,000 shares of Auction Preferred Shares ("APS").
Dividends are cumulative and the dividend rate is reset through an auction
process every 28 days. The rate in effect on April 30, 2005 was 2.450% and for
the six months then ended rates ranged from 1.500% to 2.450%.

    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 in 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 redemptions if the tests are not met.

5. 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

6. TRUST MERGER

On March 18, 2005, the Trustees of California Quality Municipal Trust,
California Municipal Trust and Trust for Investment Grade California Municipals
("Target Trusts") announced its intention to merge the Target Trusts into
California Value Municipal Income Trust ("Acquiring Trust"). The Trustees of
each of the trusts have approved in principal an agreement and plan of
reorganization between the trusts providing for a transfer of assets and
liabilities of the Target Trusts to the Acquiring Trust in exchange for shares
of beneficial interest of the Acquiring Trust (the "Reorganization"). The
Reorganization is subject to the approval by the shareholders of the Target
Trusts. The issuance of additional common shares of the Acquiring Trust is
subject to the approval of the shareholders of the Acquiring Trust.

7. 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

 20


VAN KAMPEN CALIFORNIA QUALITY MUNICIPAL TRUST

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

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.

                                                                              21


VAN KAMPEN CALIFORNIA QUALITY 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 CALIFORNIA QUALITY 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
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
prorata 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

    This Policy is not applicable to partnerships, corporations, trusts or other

accounts, 529 Educational Savings Accounts, accounts subject to the Uniform
Gifts to Minors Act, or similar accounts.

WE RESPECT YOUR PRIVACY

We appreciate that you have provided us with your personal financial
information. We strive to maintain the privacy of such information while we help
you achieve your financial objectives. This Policy describes what non-public
personal information we collect about you, why we collect it, and when we may
share it with others.

    We hope this Policy will help you understand how we collect and share
non-public personal information that we gather about you. Throughout this
Policy, we refer to the non-public information that personally identifies you or
your accounts as "personal information."

1. WHAT PERSONAL INFORMATION DO WE COLLECT ABOUT YOU?

maintain accurate information about you. We may obtain this information from
applications and other forms you submit to us, from your dealings with us, from
consumer reporting agencies, from our Web sites and from third parties and other
sources.

    For example:

     --  We may collect information such as your name, address, e-mail address,
         telephone/fax numbers, assets, income and investment objectives through
         applications and other forms you submit to us.

     --  We may obtain information about account balances, your use of
         account(s) and the types of products and services you prefer to receive
         from us through your dealings and transactions with us and other
         sources.

     --  We may obtain information about your creditworthiness and credit
         history from consumer reporting agencies.

     --  We may collect background information from and through third-party
         vendors to verify representations you have made and to comply with
         various regulatory requirements.

     --  If you interact with us through our public and private Web sites, we
         may collect information that you provide directly through online
         communications (such as an e-mail address). We may also collect
         information about your Internet service provider, your domain name,
         your computer's operating system and Web browser,

                                                             (continued on back)

2. WHEN DO WE DISCLOSE PERSONAL INFORMATION WE COLLECT ABOUT YOU?

To provide you with the products and services you request, to serve you better

about you to our affiliated companies and to non-affiliated third parties as
required or permitted by law.

about you to non-affiliated third parties include: for servicing and processing
transactions, to offer our own products and services, to protect against fraud,
for institutional risk control, to respond to judicial process or to perform
services on our behalf. When we share personal information with these companies,
they are required to limit their use of personal information to the particular
purpose for which it was shared and they are not allowed to share personal
information with others except to fulfill that limited purpose.

3. HOW DO WE PROTECT THE SECURITY AND CONFIDENTIALITY OF PERSONAL INFORMATION WE
COLLECT ABOUT YOU?

We maintain physical, electronic and procedural security measures to help
safeguard the personal information we collect about you. We have internal
policies governing the proper handling of client information. Third parties that
provide support or marketing services on our behalf may also receive personal
information, and we require them to adhere to confidentiality standards with
respect to such information.
