| Abstract: | The purpose of this study was to assess the predictive validity of observer ratings of personality and job-related competencies in a selection setting. Based on ratings from multiple raters of both the predictors and the criteria in a sample of MBA students, results indicated that observer ratings of Conscientiousness, Emotional Stability, leadership, and interpersonal skills predicted work performance, team performance, and academic performance. For work performance and team performance, a composite of the four predictors had incremental predictive validity over general mental ability, even after controlling for how well the rater knew the ratee. |
