Using Holland's theory of careers, this paper explores the relationships among personality, undergraduate training, and occupational choice. Data from the National Opinion Research Center (NORC) longitudinal study of 1961 college graduates permit multivariate analyses of the congruence among personality types, college majors, and occupations, and the extent to which incongruities lead to shifts in occupation following graduation. Preliminary results provide some support for Holland's theory, but also suggest the need to consider structural characteristics of undergraduate majors and occupations. (Author)
