REPORT OF INDEPENDENT AUDITORS
To the Board of Trustees and Shareholders of
Van Kampen Trust for Investment Grade California Municipals
In planning and performing our audit of the financial statements of Van Kampen
Trust for Investment Grade California Municipals (the "Trust") for the year
ended October 31, 2000 (on which we have issued our report dated December 6,
2000), we considered its internal control, including control activities for
safeguarding securities, in order to determine our auditing procedures for the
purpose of expressing our opinion on the financial statements and to comply with
the requirements of Form N-SAR, and not to provide assurance on the Trust's
internal control.
The management of the Trust is responsible for establishing and maintaining
internal control. In fulfilling this responsibility, estimates and judgments by
management are required to assess the expected benefits and related costs of
controls. Generally, controls that are relevant to an audit pertain to the
entity's objective of preparing financial statements for external purposes that
are fairly presented in conformity with accounting principles generally accepted
in the United States of America. Those controls include the safeguarding of
assets against unauthorized acquisition, use, or disposition.
Because of inherent limitations in any internal control, misstatements due to
error or fraud may occur and not be detected. Also, projections of any
evaluation of internal control to future periods are subject to the risk that
the internal control may become inadequate because of changes in conditions, or
that the degree of compliance with policies or procedures may deteriorate.
Our consideration of the Trust's internal control would not necessarily disclose
all matters in the internal control that might be material weaknesses under
standards established by the American Institute of Certified Public Accountants.
A material weakness is a condition in which the design or operation of one or
more of the internal control components does not reduce to a relatively low
level the risk that misstatements caused by error or fraud in amounts that would
be material in relation to the financial statements being audited may occur and
not be detected within a timely period by employees in the normal course of
performing their assigned functions. However, we noted no matters involving the
Trust's internal control and its operation, including controls for safeguarding
securities, that we consider to be material weaknesses as defined above as of
October 31, 2000.
This report is intended solely for the information and use of Trust's
management, the Board of Trustees and Shareholders of Van Kampen Trust for
Investment Grade California Municipals, and the Securities and Exchange
Commission and is not intended to be and should not be used by anyone other than
these specified parties.
