Adolescents' expectations about school and work may be key antecedents of adult attainment and this relationship may vary by specific racial, ethnic, and gender groups. This article examines how educational and occupational expectations change in adolescence and how expectations predict corresponding attainment in adulthood. Participants included African American and Hispanic females and males. Educational and occupational expectations were reported at ages 14, 16, and 18, and educational and occupational attainment at ages 20 and 26. Results indicated distinct developmental trajectories per racial or ethnic and gender group. Educational expectations were more nuanced for African American and Hispanic females than for their male counterparts; occupational expectations were more varied for Hispanic females than for other groups. Educational expectations positively predicted educational attainment for all participants, whereas occupational attainment was predicted just by educational expectations and for Hispanic females and males only.
