　　Dear Examinee:

　　As you know, due to unfortunate circumstances, ETS was forced to cancel the scores of the Octorber 1992 TOEFL administration in the People's Republic of China. At that time, you were notified that you would be able to take another TOEFL without charge up through the October 1993 administration. You should be aware that the TOEFL program has a long standing policy of not refunding test fees when administrations are cancelled.

　　We apologize for any inconvenience that this may cause to you.

　　Russell Webster

　　Executive Director
