Report of Independent Registered Public Accounting
Firm

To the Shareholders and
Board of Trustees of Voya Prime Rate Trust
In planning and performing our audit of the financial
statements of Voya Prime Rate Trust (the Trust) as of
and for the year ended February 29, 2020, in accordance
with the standards of the Public Company Accounting
Oversight Board (United States), 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 company'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 U.S. generally accepted accounting
principles. A company'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 company; (2) provide
reasonable assurance that transactions are recorded as
necessary to permit preparation of financial statements in
accordance with U.S. generally accepted accounting
principles, and that receipts and expenditures of the
company are being made only in accordance with
authorizations of management and directors of the
company; and (3) provide reasonable assurance
regarding prevention or timely detection of unauthorized
acquisition, use or disposition of a company'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 company'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 Public
Company Accounting Oversight Board (United States).
However, we noted no deficiencies in the Trust's
internal control over financial reporting and its
operation, including controls over safeguarding
securities, that we consider to be a material weakness as
defined above as of February 29, 2020.

This report is intended solely for the information and use
of management and the Board of Trustees of Voya
Prime Rate 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.
