Where Pediatricians Work Some pediatricians work in an office, either alone or with a group of other doctors, while some work in a hospital, health maintenance organization, clinic, or medical school. Still, others work as locum tenems doctors, traveling around a city or around the country, filling in for other doctors on a part-time basis.
In a residency, aspiring pediatricians have the opportunity to receive focused instruction related to children's medicine. Residents work hands-on with patients during clinical rotations. They assess their own work, as well as case studies, in meetings and group settings designed specifically for residents. According to the American Association of Medical Colleges, a pediatric residency lasts three years.
