----------------------------

This Amendment No. 21 amends the Statement on Schedule 13D (the "Schedule
13D") filed with the Securities and Exchange Commission on February 11, 2015

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,

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

(a), (b) According to the Issuer's Form 10-K filed with the Securities and
Exchange Commission on March 3, 2015, there were 67,519,701 shares of
Common Stock issued and outstanding as of February 20, 2015.  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) 17,779 shares of Common Stock held
directly by RCBA Inc., which represents 0.0% of the outstanding shares of
the Common Stock; (ii) 1,420,626 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 2.1% of the outstanding shares of the Common Stock; and
(v) 3,306,595 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 4.9% 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 4,745,000 shares of the Common
Stock, which is 7.0% 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.
