This article presents findings from a case study of a K-12 school in Turkey where teachers shared perceptions of how the International Baccalaureate Learner Profile attributes related to their own practice. While discussing the interdependency of the attributes, teachers considered that being an inquirer is the most valuable attribute for effective International Baccalaureate teachers. Participants at all grade levels believed that being open-minded and reflective were important attributes. Despite the importance of inquiry, participants shared that they feel most capable of implementing the attribute of being knowledgeable. The conceptual framework developed for this study may be used by schools and teacher educators to develop attributes of teachers who can help students become global citizens with intercultural understandings.
