It appears that students develop their motivation for self-growth through career exploration process. This study explored the relationships among career decisionmaking self-efficacy, vocational exploration activities and self-growth motivation in career exploration processes. Subjects were 224 women's junior college students majoring in liberal arts. Data were collected on two occasions in the process. At the beginning of a job-searching, the career decision-making self-efficacy expectations were measured. Eight months later, the questionnaire measuring the activity of vocational exploration and the change in self-growth motivation in their exploration process was administered to the students. These data were analyzed using covariance structure analysis. The results indicated that self-growth motivation was directly predicted by the career decision-making self-efficacy, and two factors of vocational exploration activity, i. e. collecting and integrating information about self and vocation, and reconsidering one's own vocational exploration activities. The career decisionmaking self-efficacy had a significant effect on all vocational exploration activity factors. Based on these results, the meaning of vocational exploration activity in the career development was discussed.
