Educational correlates of early and late sexual maturation in adolescence.

From the National Health Examination Survey data, 4,735 Caucasian males and females, 12 to 17 years, were classified by age and stage of sexual maturation (Tanner). Early and late maturers were each compared to all other youth of comparable age and sex, in eight education-related categories: youth and parental aspirations and expectations concerning the level of education which would be achieved by the student, teacher reports of intellectual ability and academic achievement, and test scores (WISC and WRAT). Except at age 12, late maturing boys received significantly lower ratings than mid maturers in all these areas, and early maturing males received higher ratings. For females, no differences persisted across age groups. In advising male adolescents, physicians should be alert to the possibility that school functioning may be linked to maturational processes.
