Self ratings and student ratings of 17 instructors who served as teaching assistants in a large introductory psychology course for two consecutive semesters were compared with student achievement on an externally constructed final examination. Instructor self-ratings and student ratings demonstrated good convergent validity during the second semester, especially on scales measuring student involvement in the classroom, teacher support, and teacher skill. There was significant discriminant validity, but student ratings on all scales were more highly intercorrelated than were the instructor ratings. Student ratings of the instructor's control of classroom correlated with achievement during the second semester.A number of different methods for evaluating instruction in higher education are now in use. Student ratings are still the predominant method; by comparison, instructor self-ratings and peer or colleague ratings have been used infrequently (Centra, Note 1). Much of the concern over student, peer, and self-evaluations is their relationship to student achievement, the criterion that faculty often cite as the most defensible one for assessing faculty competence. The purpose of this study was to further investigate the interrelationships among instructor self-ratings, student ratings, and student achievement.In the only study located on the relationship between instructor selfratings and student achievement, Doyle and Crichton (1978) found that the 295
