The purpose of this study is to develop a gender-based career capital accumulation model for engineering female college students. The developed model was revised and supplemented through the expert validity test and finally completed. As a result of literature and case analysis, it was suggested that career capital can be developed through the learning process, master process, and interaction process based on gender-based competencies (reflection, emotion, caring, relationship skills, and communication). Career capital consists of knowing-why, knowing-how, and knowing-whom. The knowing-why derived from this study are self-awareness, engineering interest, engineering vision, and efficacy, and the knowing-how is composed of major application ability, foreign language ability, engineering skill, and major experience, and the knowing-whom is composed of role model, mentoring, sense of community, and networking. This study model showed that career capital can be developed based on gender-based competencies, and career capital accumulation can be achieved by securing confidence, engineering knowledge, and support in the career capital development stage. Based on the model developed in this study, implications and suggestions for follow-up studies were discussed, and the results of this study can be used as useful basic data for the development of career capital accumulation programs for gender-based engineering female college students.
