Can Principals Identify Effective Teachers? Evidence on Subjective Performance Evaluation in Education
研究校长能否区分高效与低效教师，将其评价与传统薪酬决定因素（学历、经验）及基于学生成绩的增值指标对比，发现校长能识别成绩最好和最差的教师，但难以区分中间水平的教师。
We examine how well principals can distinguish between more and less effective teachers. To put principal evaluations in context, we compare them with the traditional determinants of teacher compensation—education and experience—as well as value-added measures of teacher effectiveness based on student achievement gains. We present “out-of-sample” predictions that mitigate concerns that the teacher quality and student achievement measures are determined simultaneously. We find that principals can generally identify teachers who produce the largest and smallest standardized achievement gains but have far less ability to distinguish between teachers in the middle of this distribution.
