REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Board of Trustees and Shareholders of
Van Kampen Trust for Investment Grade Municipals
In planning and performing our audit of the financial statements of Van
Kampen Trust for Investment Grade Municipals (the "Trust") as of and
for the year ended October 31, 2006 (on which we have issued our report
dated January 11, 2007), in accordance with the standards of the Public
Company Accounting Oversight Board (United States), we considered its
internal control over financial reporting, including control activities
for safeguarding securities, as a basis for designing our auditing
procedures for the purpose of expressing our opinion on the financial
statements and to comply with the requirements of Form N-SAR, but not
for the purpose of expressing an opinion on the effectiveness of the
Trust's internal control over financial reporting.  Accordingly, we
express no such opinion.
The management of the Trust is responsible for establishing and
maintaining effective internal control over financial reporting.  In
fulfilling this responsibility, estimates and judgments by management
are required to assess the expected benefits and related costs of
controls.  The Trust's internal control over financial reporting is a
process designed to provide reasonable assurance regarding the
reliability of financial reporting and the preparation of financial
statements for external purposes in accordance with generally accepted
accounting principles.  Such internal control includes policies and
procedures that provide reasonable assurance regarding prevention or
timely detection of unauthorized acquisition, use or disposition of a
Trust's assets that could have a material effect on the financial
statements.
Because of its inherent limitations, internal control over financial
reporting may not prevent or detect misstatements.  Also, projections
of any evaluation of effectiveness to future periods are subject to the
risk that controls may become inadequate because of changes in
conditions, or that the degree of compliance with the policies or
procedures may deteriorate.
A control deficiency exists when the design or operation of a control
does not allow management or employees, in the normal course of
performing their assigned functions, to prevent or detect misstatements
on a timely basis.  A significant deficiency is a control deficiency,
or combination of control deficiencies, that adversely affect the
Trust's ability to initiate, authorize, record, process or report
external financial data reliably in accordance with generally accepted
accounting principles such that there is more than a remote likelihood
that a misstatement of the Trust's annual or interim financial
statements that is more than inconsequential will not be prevented or
detected.  A material weakness is a significant deficiency, or
combination of significant deficiencies, that results in more than a
remote likelihood that a material misstatement of the annual or interim
financial statements will not be prevented or detected.
Our consideration of the Trust's internal control over financial
reporting was for the limited purpose described in the first paragraph
and would not necessarily disclose all deficiencies in internal control
that might be significant deficiencies or material weaknesses under
standards established by the Public Company Accounting Oversight Board
(United States).  However, as discussed below, we noted the following
deficiency in the design of the Fund's internal control over financial
reporting, that we consider to be a material weakness, as defined
above, as of October 31, 2006.

The Trust's controls related to the review and analysis of the relevant
terms and conditions of certain transfers of securities were not
designed to appropriately determine whether the transfers qualified for
sale accounting under the provisions of Statement of Financial
Accounting Standards No. 140 "Accounting for Transfers and Servicing of
Financial Assets and Extinguishments of Liabilities." As a result of
this weakness, material adjustments to the Trust's financial statements
and financial highlights as of and for the period ended October 31,
2006, prior to their filing, were recorded to appropriately account for
such transfers of securities as secured borrowings, rather than sales.
The effects of the adjustments on the financial statements were to
increase assets and liabilities by corresponding and equal amounts, and
to increase interest income and interest expense by corresponding and
equal amounts. Additionally adjustments were made to certain ratios
reported in the financial highlights for the current year. This
material weakness was considered in determining the nature, timing, and
extent of audit tests applied in our audit of the financial statements
as of and for the year ended October 31, 2006, of the Trust  and this
report does not affect our report on such financial statements.
This report is intended solely for the information and use of
shareholders, management and the Board of Trustees of Van Kampen Trust
for Investment Grade 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.
