This article uses Florida administrative data to evaluate the role that public high schools play in the growing female advantage in college enrollment. We first show evidence of gender sorting across public high schools that is beyond what one would observe if students were randomly assigned to their schools. Using regression and decomposition techniques, we then find that across-school gender sorting explains 12% and 16% of females' higher rates of enrollment among Hispanic and Black students, respectively. This relatively large contribution of high schools to gender disparities in college enrollment among Black and Hispanic students has implications for educators at all levels.
