I, Norman M. Levine, certify that:

1.   I have reviewed this quarterly report on Form 10-Q of DeVry
     Inc.;

2.   Based on my knowledge, this report does not contain any
     untrue statement of a material fact or omit to state a material
     fact necessary to make the statements made, in light of the
     circumstances under which such statements were made, not
     misleading with respect to the period covered by this report;

3.   Based on my knowledge, the financial statements, and other
     financial information included in this report, fairly present in
     all material respects the financial condition, results of
     operations and cash flows of the registrant as of, and for, the
     periods presented in this report;

4.   The registrant's other certifying officers and I are
     responsible for establishing and maintaining disclosure controls
     and procedures (as defined in Exchange Act Rules 13a-15(e) and
     15d-15(e)) for the registrant and have:

     a)designed such disclosure controls and procedures, or
       caused such disclosure controls and procedures to be
       designed under our supervision, to ensure that material
       information relating to the registrant, including its
       consolidated subsidiaries, is made known to us by others
       within those entities, particularly during the period in
       which this report is being prepared;

     b)designed such internal control over financial reporting,
       or caused such internal control over financial reporting
       to be designed under our supervision, to provide
       reasonable assurance regarding the reliability of
       financial reporting and the preparation of financial
       statements for external purposes in accordance with
       generally accepted accounting principles;

     c)evaluated the effectiveness of the registrant's
       disclosure controls and procedures and presented in this
       report our conclusions about the effectiveness of the
       disclosure controls and procedures, as of the end of the
       period covered by this report and based on such
       evaluation; and

     d)disclosed in this report any change in the registrant's
       internal control over financial reporting that occurred
       during the registrant's most recent fiscal quarter (the
       registrant's last fiscal quarter in the case of an annual
       report) that has materially affected, or is reasonably
       likely to materially affect, the registrant's internal
       control over financial reporting; and

49

5.   The registrant's other certifying officers and I have
     disclosed, based on our most recent evaluation of internal
     control over financial reporting, to the registrant's auditors
     and the audit committee of registrant's board of directors (or
     persons performing the equivalent functions):

      a) all significant deficiencies and material weaknesses
         in the design or operation of internal controls over
         financial reporting which are reasonably likely to
         adversely affect the registrant's ability to record,
         process, summarize and report financial information; and

      b) any fraud, whether or not material, that involves
         management or other employees who have a significant role
         in the registrant's internal controls over financial
         reporting.
