Medical residency is a post-graduate training program that a medical school graduate with a Doctor of Medicine (MD) degree takes part in to become a licensed physician. During residency, doctors work at hospitals, clinics, or medical offices to continue their education and medical training in a specialized field. Residency training may take place after receiving an MD, but it is one of the most important parts of the journey towards becoming a licensed physician. Medical residency programs are three to seven-year programs that transform med school graduates into doctors. During their residency, doctors provide direct care to patients, including diagnosing, managing, and treating health conditions and injuries. Residents practice medicine under the supervision of an attending physician, and much of the day is spent following the lead of senior doctors and taking notes. Junior residents generally start with more supervision and less complicated tasks, and responsibilities increase as residents gain education and experience. Medical residency placements may take place at a clinic or teaching hospital, and residents may work in doctors offices or outpatient clinics assisting with patient examinations and treatments. Medical residency programs allow the opportunity to gain knowledge and experience in ones chosen field of specialty and, upon completion, can lead to full licensure and the opportunity to become board-certified and practice independently without supervision.
