Residency programs are specialized training programs for medical graduates, typically lasting three to seven years. These programs provide hands-on experience in various medical fields, allowing residents to work under the supervision of experienced doctors. Residents gain practical skills and knowledge necessary for their future careers as licensed physicians. During residency, doctors-in-training rotate through different specialties, such as internal medicine, surgery, or pediatrics. This exposure helps them determine their preferred area of practice. Successful completion of a residency program is essential for obtaining board certification and practicing independently in their chosen specialty.
