This study investigated the effectiveness of a self‐appraisal‐based performance evaluation system (SABPE) that incorporates self‐assessment into traditional supervisory evaluation procedures. Its subject sample consisted of 88 faculty members and their chairpersons at a land‐grant state university. Results indicated that (1) there was high congruency between self‐ and chairperson ratings, (2) both ratings had moderate to high levels of criterion‐related validity, and (3) both faculty members and chairpersons reported high SABPE acceptance. The implications of these results for future self‐appraisal research
