As part of a 5-year study of 772 students who entered the University of Maryland, College Park, in 1980, a study was conducted of the relationship between John Holland's concept of vocational identity (sureness and confidence in one's vocational plans) and personality type (realistic, investigative, artistic, social, enterprising or conventional) to college satisfaction, retention and academic achievement. Study participants were treated as two groups, a random sample of 468 in the representative group and a black group of 339. Their scores on three instruments (My Vocational Situation, the Self-Directed Search, and the College Student Satisfaction Questionnaire) were analyzed. Results included the following: (1) no differences among the retention rates of the six personality typologies were found in the representative group, but in the black group, significant differences were found between the percentages of non-students in the artistic (39%) and investigative (7%) typologies; (2) in both groups, high levels of vocational identity were found to be associated with high grade point averages; (3) no significant differences were found among the personality types on any of the satisfaction scales for the black group, but in the representative group, social types were significantly more satisfied than investigative types with campus social life and were significantly more satisfied with the quality of their education than both artistic and conventional types; (4) both groups became increasingly confident of their vocational goals over each of the 4 survey years; and (5) no significant correlations in either group were found between grade point average and majors in programs congruent with personality type.
