Abstract: | Two hundred and thirty-six teachers were independently rated by their principals and supervisors on twenty-three scales of teacher competence. Each teacher received forty-six ratings (23 from a principal and 23 from a supervisor). The rating scales were intercorrelated and the resulting matrix factor analyzed. Two correlated factors emerged, one corresponding to principals’ ratings and the other to supervisors’ ratings. The results were interpreted to mean that the rating scales generated data that were more a reflection of the rater’s point of view than of a teacher’s actual classroom behavior. |
