Relationship between academic achievement and measured career interest: examination of Holland's theory

The present study was designed to examine Holland's hypothesis that person-environment congruence relates positively to academic achievement. The sample of 157 nontraditional premedical students completed Holland's Self-directed Search interest inventory. The students were enrolled in the Medical/Dental Education Preparatory Program, which is designed to increase the number of qualified applicants who are underrepresented in the medical profession. Using scores on Holland's inventory students were classified as congruent or incongruent. A cumulative grade point average and a science grade point average were calculated for each student. An analysis of variance supported Holland's Congruence-achievement hypothesis. Congruent students did in fact achieve significantly higher cumulative GPA and science GPA than did incongruent students. Implications for counseling and academic advisement as well as further research are discussed.
