This study explored the contribution of the approach to Iranian English language teachers' professional development. Forty general English teachers at the university level attended three supervisory sessions wherein the teachers were coached into reflective practice. Pre/postintervention semistructured interviews, classroom observations, field notes, and reflective journals were used to collect qualitative data. Thematic analysis was used to identify recurring themes at each layer of the model. Further analysis revealed a significant difference between teachers' perceptions and teaching behaviors before and after the supervisory meetings. The results demonstrated that teachers experienced a process of growth with a developmental trajectory from the outer layers to the inner layers of the onion model. As a result of the activation of core qualities through core reflection supervision, teachers developed a sense of identity and mission that had an impact on their environment, behavior, and beliefs in a way that they shifted their attention from their own concerns to their responsibilities and ideals. The findings have important implications for various stakeholders in ELT. %U http://www.teljournal.org/article_119499_349e7dc26bf93a1fec2003b68672264e.pdf
