The purpose of this study was to investigate various career paths pre-service teachers explore and the processes of establishing their commitment to becoming a teacher. A mixed-methods design was employed; 326 surveys measured the levels of pre-service teachers' career exploration and commitment using occupational identity status (achievement, moratorium, foreclosure, and diffusion), along with resilience and perceived instrumentality. Thirty-two interviews were followed to further explore detailed variations of their career decision-making journey. MANOVA analysis indicated significant differences for resilience and perceived instrumentality based on the four occupational identity statuses. Subsequent qualitative analysis identified various patterns where pre-service teachers differed in their entry motivation, negotiation for their career decision making, and the strength of their commitment to teaching. The findings of this study illuminate iterative and non-linear development of pre-service teachers' professional identity.
