This study was done to determine how selected member teachers of the Association for Business Communication (ABC) employ peer evaluation of writing in their business communication classes. A purposive sample of 78 teachers responded to a questionnaire. The findings indicate that most often the peer evaluation group ranges in size from two students to the entire class and consists of juniors and seniors who most frequently evaluate in- and out-of-class letters. Students usually use a teacher-developed, analytic scale on which they make additional comments, both positive and negative. In general, the process is successful, as revealed by a number of specific instructor comments.
