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, such as internal medicine, pediatrics, or surgery. Residents work under the supervision of experienced physicians, allowing them to develop their clinical skills and knowledge. During residency, doctors-in-training rotate through different departments, gaining exposure to various patient care scenarios. This training is essential for obtaining board certification in their chosen specialty and is a crucial step before becoming fully licensed independent practitioners.
