Given the shortage of primary care physicians, faculties of medicine have been seeking ways to encourage medical students to opt for family medicine as their career choice. The Faculty of Medicine in Geneva decided to incorporate a mandatory one-month rotation during clerkship in a primary care physician's private office. Such a learning environment offers a privileged opportunity for the student but represents a considerable challenge for clinical teachers. With the goal of identifying training priorities, we sought to investigate the differences in perception of clinical supervision held by clinical teachers and by students.
