Gender differences in teacher ratings of academic performance, social skills, and externalizing behavior were examined from fourth through seventh grade in a group of 1,023 students from 65 primary schools. Cohen's "d" and "t" tests and were used to report the magnitude of gender differences, and structural equation modeling was used to evaluate cross-domain influences in latent cascade models. Girls received significantly more positive teacher ratings than boys, but the differences leveled more out in the social and behavioral domain than in the academic. Teacher assessments of academic performance predicted future social skills to a larger extent than vice versa for both genders.
