The Board of Trustees and Shareholders of
Van Kampen Merritt Select Sector Municipal Trust:
In planning and performing our audit of the Financial statements of
Van Kampen Merritt Trust Select Sector Municipal Trust
(the "Fund") for the year ended October 31, 1994, we considered its
internal control structure, including procedures 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, not to provide
assurance on the internal control structure.
The management of the Fund is responsible for establishing and
maintaining an internal control structure. In fulfilling this
responsibility, estimates and judgments by management are
required to assess the expected benefits and related costs of
internal control structure policies and procedures. Two of the
objectives of an internal control structure are to provide
management with reasonable, but not absolute, assurance that
assets are safeguarded against loss from unauthorized use or
disposition and that transactions are executed in accordance
with management's authorization and recorded properly to
permit the preparation of financial statements in accordance
with generally accepted accounting principles.
Because of inherent limitations in any internal control
structure, errors or irregularities may occur and may not be
detected. Also, projection of any evaluation of the structure
to future periods is subject to the risk that it may become
inadequate because of changes in conditions or that the
effectiveness of the design and operation may deteriorate.
Our consideration of the internal control structure would not
necessarily disclose all matters in the internal control structure
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 the
specific internal control structure elements does not reduce to a
relatively low level the risk that errors or irregularities 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 internal control structure, including procedures for
safeguarding securities, that we consider to be material
weaknesses as defined above as of October 31, 1994.
This report is intended solely for the information and use of
management and the Securities and Exchange Commission.
