CUSIP NO. 4506B109              SCHEDULE 13D                    Page 7 of 9

Item 1.  Security and Issuer
----------------------------

This Amendment No. 3 amends the Statement on Schedule 13D (the "Schedule
13D") filed with the Securities and Exchange Commission (the "Commission") on
July 1, 2004 by Blum Capital Partners, L.P., a California limited
partnership, ("Blum L.P."); Richard C. Blum & Associates, Inc., a California
corporation ("RCBA Inc."); Blum Strategic GP II, L.L.C., a Delaware limited
liability company ("Blum GP II"); and Richard C. Blum, the Chairman and a
substantial shareholder of RCBA Inc. and a managing member of Blum GP II
(collectively, the "Reporting Persons").  This amendment relates to shares of
Common Stock, $.01 par value (the "Common Stock") of ITT Educational
Services, Inc., a Delaware corporation (the "Issuer").  The principal
executive office and mailing address of the Issuer is 13000 North Meridian
Street, Carmel, Indiana 46032-1404.  The following amendments to the Schedule
13D are hereby made.  Unless otherwise defined herein, all capitalized terms
shall have the meanings ascribed to them in the Schedule 13D.


Item 5.  Interest in Securities of the Issuer
---------------------------------------------

(a),(b) According to the Issuer's most recent Form 10-Q, there were
45,737,061 shares of Common Stock issued and outstanding as of June 30, 2004.
Based on such information, after taking into account the transactions
described in Item 5(c) below, the Reporting Persons report beneficial
ownership of the following shares of Common Stock: (i) 2,070,100 shares of
Common Stock held by Blum L.P. and RCBA Inc. on behalf of the limited
partnerships for which Blum L.P. serves as the general partner, or on behalf
of an entity for which Blum L.P. serves as investment advisor, which
represents 4.5% of the outstanding shares of the Common Stock; (ii) 2,742,700
shares of the Common Stock held by Blum GP II on behalf of the limited
partnership for which it serves as the general partner and on behalf of the
limited partnership for which it serves as the managing limited partner,
which represents 6.0% of the outstanding shares of the Common Stock; and
(iii) 59,000 shares of the Common Stock that are legally owned by The Nuclear
Decommissioning Trust of Dominion Nuclear Connecticut, Inc. ("Dominion
Connecticut") and 59,000 shares of the Common Stock that are legally owned by
Virginia Electric and Power Company Qualified Nuclear Decommissioning Trust
("Virginia Electric")(collectively, the "Investment Advisory Clients"), with
respect to which Blum L.P. has voting and investment power.  Each Investment
Advisory Client has entered into an investment management agreement with Blum
L.P., but neither Investment Advisory Client has any contract, arrangement or
understanding with the other Investment Advisory Client, or any other
Reporting Person, with respect to the acquisition, ownership, disposition or
voting of any shares of the Common Stock.  Each Investment Advisory Client
disclaims membership in a group with any Reporting Person or with the other
Investment Advisory Client, and each disclaims beneficial ownership of any
shares beneficially owned by the Reporting Persons other than for their own
account.



CUSIP NO. 4506B109            SCHEDULE 13D                     Page 8 of 9


Voting and investment power concerning the above shares are held solely by
Blum L.P. and Blum GP II.  The Reporting Persons therefore may be deemed to
be members in a group, in which case the group would be deemed to have
beneficial ownership of an aggregate of 4,930,800 shares of the Common Stock,
which is 10.8% of the outstanding Common Stock. As the sole general partner
of Blum L.P., RCBA Inc. is deemed the beneficial owner of the securities over
which Blum L.P. has voting and investment power. As Chairman, director and a
substantial shareholder of RCBA Inc., Richard C. Blum might be deemed to be
the beneficial owner of the securities beneficially owned by RCBA Inc.
Additionally, Mr. Blum may be deemed to be the beneficial owner of the
securities over which Blum GP II has voting and investment power.  Although
Mr. Blum is joining in this Schedule as a Reporting Person, the filing of
this Schedule shall not be construed as an admission that he, or any of the
other shareholders, directors or executive officers of RCBA Inc., managing
members and members of Blum GP II, is, for any purpose, the beneficial owner
of any of the securities that are beneficially owned by RCBA Inc. or Blum GP
II.

c) Since the most recent filing of Schedule 13D, the Reporting Persons
purchased the following shares of Common Stock in the open market:
