Abstract
This study examined the congruency concept in Holland's theory of vocational choice and the validity of the Self-directed Search interest inventory, utilizing a population of investigative-type students. Also examined were the race and sex differences in students' responses to Holland's six personality types. The sample of 100 black and white premedical students were enrolled in a medical education preparatory program. The program was designed to increase the number of qualified applicants who are underrepresented in the medical profession. The analysis produced positive support for Holland's congruency concept and the concurrent validity of the Self-directed Search. No significant differences were noted for race, although sex yielded significant differences for Holland's Realistic and Investigative personality types.
