SEI INSTITUTIONAL INTERNATIONAL TRUST

                           INTERNATIONAL EQUITY FUND

                       SUPPLEMENT DATED DECEMBER 21, 2000
                    TO THE PROSPECTUS DATED JANUARY 31, 2000

THIS SUPPLEMENT PROVIDES NEW AND ADDITIONAL INFORMATION BEYOND THAT CONTAINED IN
THE CLASS D PROSPECTUS, AND SHOULD BE READ IN CONJUNCTION WITH SUCH PROSPECTUS.

As of the date of this supplement, offering of the Class D shares of the
International Equity Fund (the "Fund") of SEI Institutional International Trust
(the "Trust") will terminate.

At the December 11, 2000 meeting of the Board of Trustees, the Board of
Trustees, including all of the Trustees who are not "interested persons" (as
defined in the Investment Company Act of 1940) of the Trust approved of closing
the Class D shares of the Fund to new purchases immediately, and to a mandatory
redemption of all Class D shares of the Fund, at net asset value per share, on
January 31, 2001.

The decision to have the Fund redeem all outstanding Class D shares was based on
the lack of sales of Class D shares and limited size of the class, a change in
ownership of the primary dealer of Class D shares, and anticipated termination
of the Fund's distribution arrangements with such dealer. As is the case with
other redemptions, the mandatory redemption will constitute a taxable
disposition of shares for shareholders who do not hold their shares through
tax-advantaged plans.

The prospectus is hereby amended to reflect these changes.
