The present study evaluated the effectiveness of performance appraisal training in an organizational setting. Four hundred and two middle level managers were randomly assigned to one of three conditions: no training, computer assisted instruction only (CAI), or CAI training plus a behavior modeling workshop (CAIW). Training effectiveness was assessed on two categories of dependent variables, managerial learning and managerial job performance. As predicted trained managers were found to be more knowledgeable of performance appraisal than untrained managers. Also as predicted, managers in the CAIW group conducted appraisal discussions which were perceived by employees as more satisfying than employees of managers in the no training group. Only partial support was obtained for the hypothesis that trained managers would be more effective in completing performance appraisal forms.
