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

Trust Report

FOR THE 6-MONTH PERIOD ENDED APRIL 30, 2005

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

MARKET CONDITIONS

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

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

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

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 the trust 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.

During the reporting period, we remained focused on keeping the portfolio's
credit quality high. Seventy-eight percent of the bonds in the portfolio were
rated AAA at the close of the period. However, as high-yield spreads continued
to tighten, lower quality bonds tended to perform better. Additionally, due to
our concerns about the long-term merits of tobacco bonds, we did not include
them in the portfolio. This decision prevented the trust from participating in
the short-term rebound experienced by tobacco and other lower-rated bonds during
the period.

                                                                               3


One of our primary strategies in managing the trust was to take advantage of
what we believed to be compelling opportunities in the 25- to 30-year segment of
the market. We focused here on purchasing securities with premium (that is,
above-market) coupons and moderate interest rate sensitivity.

Our purchases of these securities were funded by the proceeds of sales of
several shorter-maturity positions, many of which had been refunded during the
period. This was part of our ongoing strategy of positioning the trust for an
environment of rising short-term interest rates by limiting the trust's exposure
to that segment of the market. 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 and remained especially selective
regarding the health care sector. We also avoided zero coupon bonds. Public
education, tax districts, and public building 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.

(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 $.01, decrease net realized and unrealized gains and
   losses per share by $.01 and increase the ratio of net investment income to
   average net assets applicable to common shares from 7.11% to 7.13%. Per
   share, ratios, and supplemental data for periods prior to October 31, 2002
   have not been restated to reflect this change in presentation.

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

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

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

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

VAN KAMPEN TRUST FOR INVESTMENT GRADE CALIFORNIA MUNICIPALS

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

1. SIGNIFICANT ACCOUNTING POLICIES

Van Kampen Trust for Investment Grade California Municipals (the "Trust") is
registered as a diversified, closed-end management investment company under the
Investment Company Act of 1940, as amended. The Trust's investment objective is
to provide a high level of current income exempt from federal 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. The Trust commenced investment
operations on March 27, 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.
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 $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

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 $2,200 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 $16,600
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.

    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

5. PREFERRED SHARES

As of April 30, 2005, the Trust has outstanding 1,800 Auction Preferred Shares
("APS"). Dividends are cumulative and the dividend rate is currently reset every

2.250%. During the six months ended April 30, 2005, rates ranged from 1.250% to
2.250%.

    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

The Trust is subject to certain asset coverage tests and the APS are subject to
mandatory redemption if the tests are not met.

Trust's maximum exposure under these arrangements is unknown. However, the Trust

7. TRUST MERGER

On March 18, 2005, the Trustees of Trust for Investment Grade California
Municipals, California Quality Municipal Trust, and California Municipal Trust
("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.

8. DERIVATIVE FINANCIAL INSTRUMENTS

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

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

                                                                              19
