1. This article examines how teachers assess the performance of principals based on a study using data from the 1987-1988 School and Staffing Survey (SASS). 2. The study found that teachers tend to rate principals of the same gender or race more positively. Specifically, female teachers consistently gave female principals higher ratings, viewing them as more helpful, supportive, and better leaders. Male principals received significantly lower ratings. 3. Additional findings include teaching experience receiving higher performance ratings from teachers than other credentials. Graduate training, even in school administration, was associated with lower ratings. Effective principals were characterized as having a clear vision and knowledge of teaching to guide instruction.
