EXHIBIT 18

August 10, 2005

Computer Task Group Inc.
Buffalo, New York

Ladies and Gentlemen:

We have been furnished with a copy of the quarterly report on Form 10-Q of
Computer Task Group, Inc. (the "Company") for the three and six-month periods
ended July 1, 2005, and have read the Company's statements contained in Note 6
to the consolidated financial statements included therein. As stated in Note 6,
the Company changed its method of accounting for reporting changes in interim
periods to liabilities resulting from changes in judgments or settlements
related to tax exposure items and states that the newly adopted accounting
principle is preferable in the circumstances because it better reflects the
Company's consolidated financial position and operations at the time of the
change in tax exposure items. The Company had previously accounted for such
changes in judgments or settlements as adjustments to the estimated annual
effective tax rate. Under the new method, such changes in judgments or
settlements are recorded as discrete items in the interim period in which the
change occurs. In accordance with your request, we have reviewed and discussed
with Company officials the circumstances and business judgment and planning upon
which the decision to make this change in the method of accounting was based.

We have not audited any financial statements of the Company as of any date or
for any period subsequent to December 31, 2004, nor have we audited the
information set forth in the aforementioned Note 6 to the consolidated financial
statements; accordingly, we do not express an opinion concerning the factual
information contained therein.

With regard to the aforementioned accounting change, authoritative criteria have
not been established for evaluating the preferability of one acceptable method
of accounting over another acceptable method. However, for purposes of the
Company's compliance with the requirements of the Securities and Exchange
Commission, we are furnishing this letter.

Based on our review and discussion, with reliance on management's business
judgment and planning, we concur that the newly adopted method of accounting is
preferable in the Company's circumstances.

Very truly yours,

                                  /s/ KPMG LLP

                                       22
