This article aims to examine the process of critical professional identity development as it was perceived by the teacher candidates who participated in the service-learning programme. This study presents three main processes that took place in the development of a critical professional identity among teacher candidates during service-learning. These processes included the following: (1) Deconstructing stereotypes through engagement with the ‘other', (2) Coping with difficulties, dilemmas or conflicts that arise from dialogue with the ‘other', and (3) Shifting from a hegemonic professional perception to a dialogic one.
