Lack of research on the characteristics of peer assessment in EFL writing may inhibit teachers from appreciating the utility of this innovative assessment. This study addressed the following research questions: (1) How similar are peer, self- and teacher ratings of EFL writing?; (2) Do students favour peer ratings?; and (3) Does peer feedback influence students' attitudes about peer rating? Forty-seven college students studying English writing in a Japanese college were assigned to write two essays. Each essay was commented on and rated by two teachers, three peers and the writers themselves. Students also completed a five-item questionnaire about their attitudes regarding peer rating. Peer and teacher ratings were found to correlate significantly. The results of the questionnaire indicated that students had favourable attitudes towards peer rating. A regression analysis suggested that peer feedback did not influence students' favourable attitudes about the feedback. (Contains 4 notes and 8 tables.)
