Abstract:

This study investigates whether within-school sorting increases socioeconomic test score inequalities. Using universal test score data on 6th- and 8th-grade students in Hungary, we document the extent of within-school sorting in an institutional context where sorting based on ability or prior achievement is rare. We identify sorting schools as schools that systematically assign students with low and high socioeconomic status into different classrooms within the school. Then, exploiting school fixed effects and quasi-exogenous variation in sorting induced by enrollment and class size rules, we show that sorting has a significant and economically meaningful effect on test score inequalities between students from different socioeconomic backgrounds. Sorting harms low-status students, while high-status students gain much less, if anything, from attending sorting schools. We attribute our findings to the within-school reallocation of educational resources and differences in educational practices.
