The precollege career choices of National Merit Scholars and the extent to which these choices remained stable or changed 7 to 8 years after these students entered college were determined. From 1956 through 1960, the students' vocational plans were obtained from a personal data form completed during their senior year in high school. These same scholars submitted information concerning their career plans or choices in the Summer of 1965. The most popular initial choices among men were the physical sciences, mathematics and engineering. Among women, the physical sciences, mathematics and education were most often chosen. From the data collected in 1965, it was evident that a considerable change in career objectives occurred in both sexes. Among men, engineering suffered the greatest loss of talent to other career fields. Medicine, law and the biological sciences were the only fields keeping at least 50 percent of their initial recruits. Education initially attracted large proportions of women, but subsequently lost many of them to other fields. (CS)
