Using the data from Project Talent and the Growth Study conducted by Educational Testing Service, this study determined the changes from 1961 to 1967 in the proportion of high school graduates, categorized by ability and socioeconomic status (SES), who made particular post-high school educational decisions. For males, the educational alternatives were: four-year college; junior college; technical or trade school; armed forces school, or none. For females, the choices were: four-year college, junior college; nursing school; secretarial, business or technical school; or none. The following conclusions were reached: (1) students pursuing some kind of postsecondary education increased for all SES groups for each sex; (2) male increases were greater for lower ability and lower SES groups, while for females, the increase was related only to ability; (3) four-year college attendance increased for all groups except lower ability males; (4) technical-trade school attendance increased slightly for males, primarily for lower ability and lower SES students; (5) technical-trade school attendance decreased slightly for females; (6) there was a large increase in junior college attendance, particularly among lower ability students; and (7) four-year college attendance decreased most for low ability, high SES students.
