Data from the Cooperative Institutional Research Programs at ACE/UCLA on a national sample of students who first matriculated as college freshmen in 1966 were merged with followup data collected in 1967, 1970, and 1971. Cross-tabulations specify the level of career aspirations for women and men across the college years and across cohorts of college freshmen between 1966 and 1976. Multivariate regression analyses identify the characteristics of family background, personality, and college environment associated with changes in women's career aspirations from college matriculation to graduation and beyond. Separate regression results are presented for women and men with initially high and modest career plans. (Author)
