INDEPENDENT AUDITORS' REPORT
To the Board of Directors and Shareholders of
The BlackRock New Jersey Investment Quality
Municipal Trust
In planning and performing our audit of the
financial statements of The BlackRock New Jersey
Investment Quality Municipal Trust (the "Trust")
for the year ended October 31, 2000 (on which we
have issued our report dated December 8, 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
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 management, the Board of Directors and
Shareholders of The BlackRock New Jersey
Investment Quality Municipal Trust, and the
Securities and Exchange Commission, and is not
intended to be and should not be used by anyone
other than these specified parties.
