Swedish society has become more socially diverse in terms of ethnic background and cultural differences. In response to this fact, it is emphasised that teachers should have the skills to develop a culturally responsive pedagogy. The study described in this chapter focuses on how the mentorship model which is a part of the teacher training programme at one university supports teacher students in their efforts to develop this competence. The mentorship model is an attempt to ease teacher students’ efforts to develop professional knowledge and their transition from becoming a teacher to working as one. The present study focuses on how the mentorship model achieves its aim by promoting the teacher students’ professional reflection and preparation about culturally diverse school settings.
