The purpose of this study is to identify the predicting factors that distinguish teacher education graduates with a low level from those with a high level of teaching commitment. The results suggest that graduates with a low level of teaching commitment can be reliably distinguished from graduates with a high level of commitment by the personality factor ‘conscientiousness’, the type of teacher training, their initial motivation for teaching, their views of their teacher education (in terms of preparation for teaching, faculty support and mentor support) and their teacher efficacy.
