INTERNAL CONTROL RPT

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders and the Board of Trustees of The Alger Institutional Funds:

In planning and performing our audits of the financial statements of The Alger
Institutional Funds (the "Trust"), including the Alger Capital Appreciation
Institutional Fund, Alger Focus Equity Fund, Alger Mid Cap Growth
Institutional Fund, and Alger Small Cap Growth Institutional Fund, as of and
for the year ended October 31, 2019, in accordance with the standards of the
Public Company Accounting Oversight Board (United States) (PCAOB), we
considered the Trust's internal control over financial reporting, including
controls over 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-CEN, 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. A 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. A trust's internal control over financial
reporting includes those policies and procedures that (1) pertain to the
maintenance of records that, in reasonable detail, accurately and fairly
reflect the transactions and dispositions of the assets of the trust; (2)
provide reasonable assurance that transactions are recorded as necessary to
permit preparation of financial statements in accordance with generally
accepted accounting principles, and that receipts and expenditures of the
trust are being made only in accordance with authorizations of management and
trustees of the trust; and (3) 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 deficiency in internal control over financial reporting 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 material weakness is a deficiency, or a
combination of deficiencies, in internal control over financial reporting,
such that there is a reasonable possibility that a material misstatement of
the trust's annual or interim financial statements will not be prevented or
detected on a timely basis.

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
material weaknesses under standards established by the PCAOB. However, we
noted no deficiencies in the Trust's internal control over financial reporting
and its operation, including controls for safeguarding securities, that we
consider to be a material weakness, as defined above, as of October 31, 2019.

This report is intended solely for the information and use of management and
the Board of Trustees of the Fund and the Securities and Exchange Commission
and is not intended to be and should not be used by anyone other than these
specified parties.
