%X Numerous studies investigate high-stakes personnel evaluation systems in education, but nearly all focus on evaluation of teachers. We instead examine the evaluation of school principals at scale using data from the first 4 years of implementation of Tennessee¡¯s multiple-measure administrator evaluation system. We focus specifically on the rubric-based practice ratings given by principals¡¯ supervisors that constitute one half of principals¡¯ overall evaluation scores. We find that supervisors¡¯ ratings are internally consistent, relatively stable over time, and predictive of other performance measures, such as student achievement growth and teachers¡¯ ratings of school leadership quality. However, raters fail to differentiate dimensions of principal practice, and ratings may be biased by factors, such as school poverty, outside the principal¡¯s control
