As medical trainees progress through their education, they experience multiple transitions to new roles with increasing autonomy and decreasing supervision. These transitions contribute to trainees' formation of identities as physicians. 1,2 Two articles in this issue of Medical Education provide rich accounts of trainees' transitions at different stages of medical education.
