We adopted the perspectives of organizational support and self-regulation to examine how counseling and individual management, respectively, moderate career competencies to predict career success. Hierarchical linear modelling was conducted with 604 employees and 217 managers of 26 manufacturing companies in Taiwan. As we predicted, our results showed that career competencies were positively related to career success. Also, career counseling and individual career management were found to have a moderating effect on the relationship between career competencies and subjective career success. Implications and limitations of the findings are discussed.
