This dissertation contributes to the scholarship surrounding the development of international mindedness in teacher candidates. Phenomenological interview techniques were used to explore the experiences and perceptions of teacher candidates who enrolled in an undergraduate teacher preparation program leading to the International Baccalaureate educator certificate. By highlighting the teacher candidates, this study captured the strengths, challenges, and needs unique to this group. The findings can inform an understanding of how international mindedness develops in teacher candidates and subsequently how it is enacted, identifying curricular and instructional supports in practice that best support this learning. This study will also inform teacher educators and policy makers who are considering integrating the IB teacher certification into existing curriculum.
