While most studies have focused primarily on the correlates of career barriers, research examining specific career barrier typology experienced among college students remains limited. Employing cluster analysis, this study explored the career barrier typology of 318 college students using the Korean college students’ Career Barrier Inventory (KCBI). The variables used in this study included ‘personality’ (hardiness, trait anxiety, locus of control, resilience, and optimism) and ‘career maturity attitude’. Two major conclusions were drawn. Firstly, cluster analysis of the KCBI identified four groups of participants; (a) a salient external career barrier group, (b) a well adjusted group, (c) a salient internal career barrier group, and (d) the worst career barrier group. Secondly, the results suggest discrepant differences of personality variables and career attitude maturity among the clustered groups. Limitations of the present study and suggestions for future research are also discussed.
