Report of Independent Registered Public Accounting Firm

To the Board of Trustees of Vanguard STAR Funds and Shareholders
of
Vanguard Total International Stock Index Fund

In planning and performing our audit of the financial statements of
Vanguard Total International Stock Index Fund (one of the funds
constituting Vanguard STAR Funds, referred to hereafter as the "Fund")
as of and for the year ended October 31, 2021, in accordance with the
standards of the Public Company Accounting Oversight Board (United
States) (PCAOB), we considered the Fund'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 Fund's internal control over
financial reporting. Accordingly, we do not express an opinion on the
effectiveness of the Fund's internal control over financial reporting.

The management of the Fund 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 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 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 Fund'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 over financial
reporting that might be material weaknesses under standards
established by the PCAOB. However, we noted no deficiencies in the
Fund'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 October 31, 2021.

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