        SECTION 302 (a) CERTIFICATIONS
  I,
        Janice
        B. Fuellhart, certify that:
 
 1.
        I have
        reviewed this quarterly report on Form 10-QSB of ICF Corporation;
 
 2.
        Based
        on my knowledge, this quarterly 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 quarterly
        report;
 
 3.
        Based
        on my knowledge, the financial statements, and other financial information
        included in this quarterly 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 quarterly 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-14 and 15d-14) for the registrant and we have:
 
 a)
              Designed
                  such disclosure controls and procedures 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 quarterly report is
                  being
                  prepared;
 b)
              b)
                  Evaluated the effectiveness of the registrant's disclosure controls
                  and
                  procedures as of a date within 90 days prior to the filing date
                  of this
                  quarterly report (the "Evaluation Date");
                  and
 
 c)
              Presented
                  in this quarterly report our conclusions about the effectiveness
                  of the
                  disclosure controls and procedures based on our evaluation as of
                  the
                  Evaluation Date;
 
 5.
        The
        registrant's other certifying officers and I have disclosed, based on our
        most
        recent evaluation, to the registrant's auditors and the audit committee of
        registrant's board of directors (or persons performing the equivalent function):
  a)
              All
                  significant deficiencies in the design or operation of internal
                  controls
                  which could adversely affect the registrant's ability to record,
                  process,
                  summarize and report financial data and have identified for the
                  registrant's auditors any material weaknesses in internal controls;
                  and
 b)
              b)
                  Any fraud, whether or not material, that involves management or
                  other
                  employees who have a significant role in the registrant's internal
                  controls; and
 
 6.
        The
        registrant's other certifying officers and I have indicated in this quarterly
        report whether or not there were significant changes in internal controls
        or in
        other factors that could significantly affect internal controls subsequent
        to
        the date of our most recent evaluation, including any corrective actions
        with
        regard to significant deficiencies and material weaknesses.
