Participants were 12 to 17 years old and completed multiple self-reported questionnaires. Regression analyses and latent moderation…

High-achieving minority students have fewer friends than their majority counterparts. Exploring patterns of friendship formation in the Add Health data, we find strong racial homophily in friendship formations as well as strong achievement homophily within race. However, we find that achievement matters less in cross-racial friendships. As a…
