In this article, we review key factors in promoting a culturally diverse and inclusive learning environment for all undergraduate medical students, and the role of primary care educators in preparing students to work with diverse teams, patients and communities. These factors include approaches to curriculum and assessment, student community, faculty development and recruitment, and wider institutional factors. By highlighting these, including areas where further research, evaluation and consensus are needed, we hope to support further discourse on how primary care educators can promote culturally diverse and inclusive undergraduate medical education.
