Students become medical doctors (MDs) or doctors of osteopathy (DOs, for osteopathic medical schools) after graduation from medical school, but to become licensed to practice medicine, physicians must complete at least 1 year of post-medical school education and training. The first year of this training is called internship or first-year residency. Most physicians, and any who practice a specialty of medicine, complete a residency. Residencies are several years of further education and training in a specific area of medicine. The September 15, 2010, issue of JAMA is a theme issue about medical education and includes articles about the education and training of physicians.
