ORGANIZATION AND RATER DIFFERENCES IN PERFORMANCE APPRAISALS

This study examines the effects of organizational differences and rater differences on performance appraisals. Self, peer, and supervisory ratings of performance for nurses in four hospitals and self, student, peer, and supervisory ratings for resident advisors in seven university dormitory complexes were used in this study. The analyses indicate that both organization and rater differences have significant, independent effects on performance ratings. The findings suggest that organizational differences may restrict the generality of the findings of performance appraisal studies across organizational settings. They also may have a negative impact on the usefulness of any particular performance appraisal form in different settings, and on the ability of managers to accurately interpret and compare performance ratings for individuals in different organizational subunits.
