Dear Sir/Madam:

The representations made in this letter are based solely on discussions with and
representations from the engagement partner and manager on the audit of the
financial statements of this registrant for the current fiscal year. Those
individuals are no longer with Arthur Andersen LLP. We have read the three
paragraphs of Item 4 included in the Form 8-K dated June 20, 2002 of PAREXEL
International Corporation to be filed with the Securities and Exchange
Commission and have found no basis for disagreement with the statements
contained therein.

Very truly yours,

/s/ Arthur Andersen LLP

Arthur Andersen LLP
