This study explores the career development of women during the five year period after high school, examining the determinants of that development and presenting data which may provide a basis for better vocational guidance and a theory of occupational choice in women. The study employs longitudinal data from the Project TALENT data bank and 17,009 women were analyzed in total. From the predictor variables employed, career choices of women after high school could be predicted with some degree of accuracy. Post high school experiences were the best determinants of career outcomes. Educational attainment and marital-familial status best predicted whether women would choose careers in the professions or be housewives and office workers. Of the personal variables, scholastic aptitude and socioeconomic status as well as early career choices, were the best predictors. However, different clusters of characteristics were predictive of different outcomes. (EK)
