The Faculty of Medicine of Chiba University implements a curriculum for education on professionalism for students in multiple school years. The curriculum is designed to promote education solely for the Faculty of Medicine and that for interprofessional collaboration. Junior students attend lectures and workshops, which also involve patients, to learn about the definition of professionalism and ethics, and undergo the shadowing method to learn the necessary attitudes and behaviors as professionals from physicians prior to clinical training. In the clinical training, students attend workshops twice to reflect on their attitudes and behaviors from the viewpoint of professionalism. The interprofessional education program encourages students in each school year to learn skills required for interprofessional collaboration along with students of the Faculties of Nursing and Pharmacy. Students establish their identities as professionals - the most important goal for medical education, by comparing themselves with other health care professionals. It is important to implement both programs designed for the Faculty of Medicine and the promotion of education for interprofessional collaboration to help students establish their identities as professionals.
