This document summarizes a research study that examined the relationship between principals' ethnicity and gender and the suspension of African American students. The study analyzed suspension data from a small urban school district where African American students made up the majority of suspensions. The study found significant relationships between the ethnicity and gender of principals and the suspension rates, duration, and types of infractions of suspended students. Specifically, African American students received longer suspensions and were suspended for more subjective infractions when the suspending principal was white.
