A study was undertaken to identify the kinds and extent of sex discrimination in access to postsecondary education. The study examined: (1) the participation of women in educational activities (secondary schools and postsecondary collegiate and noncollegiate institutions); (2) the effect of differential socialization and socioeconomic status on women's aspirations, self-concept, and motivation; (3) institutional practices that may be discriminatory, individual behavior that may limit women's options, and specific aspects of the educational experience that contribute to women's progress; and (4) the mature woman's access to education. The implications of the study are that: (1) program efforts should be undertaken for high school preparation, participation in postsecondary education, and institutional practices and policies; (2) there is a need for both periodic data collection from high school students and studies to identify the factors that affect women's career decisions; and (3) legislative efforts that go beyond Title IX are needed.
