This study examined relationships between the economic, human, social, and cultural capital of families and adolescents' academic achievement. Data were collected from 387 14-yr.-old Hong Kong students (187 girls, 200 boys), who completed questionnaires to assess their perceptions of the various dimensions of family capital. Academic achievement was measured by performance in Chinese language, English language, and mathematics. The findings indicated that different combinations of the dimensions of family capital combined to contribute to moderate amounts of variance in adolescent girls' academic performance, whereas social capital was the only family measure to have a meaningful and significant modest association with adolescent boys' academic achievement.[Reproduced with permission of author(s) and publisher from: Majoribanks, Kevin, & Kwok, Yanny.
