This study investigated the links between racial discrimination and school engagement and the roles of racial socialization and ethnic identity as protective factors in those linkages in a sample of 148, sixth through twelfth grade African American adolescents from working and middle-class two-parent families. In home interviews, youth described their ethnic identity, discrimination experiences at school, and school engagement (school bonding, school grades, school self-esteem), and parents rated their racial socialization practices. Analyses revealed that discrimination was negatively related to school self-esteem and school bonding. Racial socialization had additive effects on school self-esteem and school bonding, but did not moderate the discrimination--school engagement association. For boys, ethnic identity had additive effects on school bonding, but for girls, ethnic identity moderated the relation between discrimination and school bonding: when girls experienced more discrimination and had a lower ethnic identity, they reported lower school bonding. Discrimination, racial socialization, and ethnic identity were not related to school grades. (Contains 2 tables and 1 figure.)
