Using a sample drawn from Taiwan, this study evaluated the role of mother and father involvement in adolescent academic achievement. The participants were drawn from the Taiwan Education Panel Survey (TEPS) and consisted of 8,108 adolescents who studied seventh grade in 2001. Father and mother involvement related to academic achievement was measured by four types of involvement: career plan discussion, listening to adolescent thinking, monitoring academic progress, and participation in school activities. The results indicated that mothers were more involved than fathers in education and that mother involvement had more predictive power of adolescent academic achievement.
