The Effect of School Rank on Personality Traits

Abstract

We study the effect of classroom rank on high-school students’ Big Five personality traits. We exploit idiosyncratic differences in the class distribution of earlier academic achievement. Such differences generate quasi-random variation in class rank for students with the same initial achievement. We find a positive and sizeable effect of rank on conscientiousness, but we find no effects on the other four personality traits. A thorough analysis of the mechanism suggests that the primary channels through which class rank improves conscientiousness are perceived ability and academic motivation.
