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

This Amendment No. 4 amends the Statement on Schedule 13D (the "Schedule 13D")
filed with the Securities and Exchange Commission on August 13, 2007 by Blum

Delaware limited liability company ("Saddlepoint GP") (collectively, the
"Reporting Persons").

This amendment to the Schedule 13D relates to shares of common stock, $.01 par
value per share (the "Common Stock") of Career Education Corporation, a
Delaware corporation (the "Issuer").  The principal executive office and
mailing address of the Issuer is 2895 Greenspoint Parkway, Suite 600, Hoffman

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

(a), (b) According to the Issuer's Form DEF 14A filed with the Securities and
Exchange Commission on April 2, 2008, there were 89,480,978 shares of
Common Stock issued and outstanding as of March 17, 2008.  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) 2,917,565 shares of Common Stock held by Blum LP
and RCBA Inc. on behalf of the limited partnerships for which Blum LP serves
as the general partner, which represents 3.3% of the outstanding shares of the
Common Stock; (ii) 6,604,096 shares of the Common Stock held by Blum GP III
which serves as general partner of Blum GP III LP which, in turn, serves as
the general partner of Blum Strategic III, which represents 7.4% of the
outstanding shares of the Common Stock; (iii) 4,690,100 shares of the Common
Stock held by Blum GP IV which serves as general partner of Blum GP IV LP
which, in turn, serves as the general partner of Blum Strategic IV, which
represents 5.2% of the outstanding shares of the Common Stock; (iv) 464,900
shares of the Common Stock held by Saddlepoint GP on behalf of a partnership
for which it serves as the general partner, which represents 0.5% of the
outstanding shares of the Common Stock; and (v) 164,500 shares of the Common
Stock that are legally owned by The Nuclear Decommissioning Trust of Dominion
Nuclear Connecticut, Inc. ("Dominion Connecticut"), which represents 0.2% of
the outstanding shares of the Common Stock and 164,500 shares of the Common
Stock that are legally owned by Virginia Electric and Power Company Qualified
Nuclear Decommissioning Trust ("Virginia Electric"), which represents 0.2% of
the outstanding shares of the Common Stock (collectively, the "Investment
Advisory Clients"), with respect to which Blum LP has voting and investment
power.  Each Investment Advisory Client has entered into an investment
management agreement with Blum LP, 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. 141665109             SCHEDULE 13D                     Page 13 of 15


Voting and investment power concerning the above shares are held solely by
Blum LP, Blum GP III, Blum GP IV and Saddlepoint GP. 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 15,005,661
shares of the Common Stock, which is 16.8% of the outstanding Common Stock. As
the sole general partner of Blum LP, RCBA Inc. is deemed the beneficial owner
of the securities over which Blum LP has voting and investment power. The
filing of this Schedule shall not be construed as an admission that any of the
shareholders, directors or executive officers of RCBA Inc. or the managing
members and members of Blum GP III, Blum GP III LP, Blum GP IV, Blum GP IV LP
and Saddlepoint GP, is, for any purpose, the beneficial owner of any of the
securities that are beneficially owned by RCBA Inc., Blum GP III LP, Blum GP
III, Blum GP IV LP, Blum GP IV or Saddlepoint GP.

c) During the last 60 days, the Reporting Persons purchased the following
shares of Common Stock in the open market:
