This monograph reports a 10 year followup study of approximately 200 junior high school boys to determine their transition from school to college and to work. The purpose of this monograph is to describe their careers and to analyze the possible determinants of their careers. All living subjects were located and 94 percent were contacted in person with coordinated interviews, questionnaires, and tests to bring the information about their family, educational, military, and work histories up to date. Predictor variables in this study consist of standard measures of intelligence, parental occupational level, school achievement and participation, community participation, peer acceptance, and level of vocational aspiration. In addition, measures were taken to assess readiness for vocational planning. Criterion variables consist of measures of career and of occupational success or satisfaction, including vocational coping behaviors and measures of career development and occupational status up to or at age 25.
