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

This Amendment No. 11 amends the Statement on Schedule 13D (the "Schedule
13D") filed with the Securities and Exchange Commission on February 28, 2012
by Blum Capital Partners, L.P., a California limited partnership, ("Blum LP");
Richard C. Blum & Associates, Inc., a California corporation ("RCBA Inc.");
Blum Strategic GP III, L.L.C., a Delaware limited liability company ("Blum GP
III"); Blum Strategic GP III, L.P., a Delaware limited partnership ("Blum GP
III LP"); Blum Strategic Partners III, L.P., a Delaware limited partnership
("Blum Strategic III"); Blum Strategic GP IV, L.L.C., a Delaware limited
liability company ("Blum GP IV"); and Blum Strategic GP IV, L.P., a Delaware
limited partnership ("Blum GP IV LP"); Blum Strategic Partners IV, L.P., a
Delaware limited partnership ("Blum Strategic IV") (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 231 N. Martingale Road, Schaumburg,
Illinois 60173.

The following amendments to the Schedule 13D are hereby made. Unless otherwise
defined herein, all capitalized terms shall have the meaning ascribed to them
in the Schedule 13D as previously amended.

There have been no changes to Item 2 since the Schedule 13D Amendment filed on
February 28, 2012.

CUSIP NO. 141665109             SCHEDULE 13D                     Page 11 of 13


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

(a), (b) According to the Issuer's 10-Q filed with the Securities and
Exchange Commission on May 10, 2012, there were 67,233,533 shares of
Common Stock issued and outstanding as of April 30, 2012.  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) 192 shares of Common Stock held directly by RCBA
Inc.; (ii) 546,081 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 0.8% of the outstanding shares of the Common Stock;
(iii) 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 9.8% of the outstanding shares
of the Common Stock; and (iv) 6,666,593 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 9.9% of
the outstanding shares of the Common Stock.

Voting and investment power concerning the above shares are held solely by
Blum LP, Blum GP III and Blum GP IV. 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 13,816,962 shares of the Common
Stock, which is 20.6% 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 and Blum GP IV LP, 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
and Blum GP IV.

(c) Since the last Schedule 13D Amendment filed on April 3, 2012, the
Reporting Persons have made the following transactions in the Common Stock of
the Issuer:

Entity                             Trade Date    Shares    Price/Share
-------                            ----------   --------   -----------

which Blum LP serves as the        05-02-2012     60,139        6.7922
