Residents are mentored by peers, clinical faculty, and even research faculty. Interns have an R2 mentor, R1s have a R3 mentor, and R2s have an R4 mentor so that each resident will experience both “mentee” and “mentor” roles during residency. Faculty mentors assist with career and professional development. Peer mentors provide collegial support and guidance about study plans, rotation preparation, board exams, call, fellowships, and other aspects of resident life.
