RT Journal Article SR Electronic T1 School Principal Race, Teacher Racial Diversity, and Student Achievement JF Journal of Human Resources JO J Hum Resour FD University of Wisconsin Press SP 666 OP 712 DO 10.3368/jhr.58.4.0218-9328R2 VO 58 IS 2 A1 Bartanen, Brendan A1 Grissom, Jason A. YR 2023 UL http://jhr.uwpress.org/content/58/2/666.abstract AB Exploiting variation from principal and teacher transitions over long administrative data panels from Missouri and Tennessee, we estimate the effects of principal race on the racial composition of a school’s teachers. Evidence from the two states is strikingly similar. Principals increase the proportion of same-race teachers in the school by 1.9–2.3 percentage points, on average. Both increased hiring and increased retention of same-race teachers explain this compositional change. Further, leveraging longitudinal student-level data from Tennessee, we find that having a same-race principal improves math achievement, but this effect largely operates through avenues other than the racial composition of the teaching staff.
