This chapter examines the crucial role of reflection in mentoring pre-service teachers, emphasizing the divergent nature of practicum experiences and the need for tailored mentorship. It introduces the “Mentorship Dimensions,” a tool developed through 7 years of case-study research to support reflective practice. This tool can help university advisors, classroom teachers, and school leaders critically engage with their approaches to both mentorship and supporting the development of reflective practices. By providing a reflective tool and demonstrating its application in case examples, this chapter aims to enhance mentorship through the development of reflective practices in teacher-education practica.
