Medical school departments of psychiatry ("psychiatry departments"), defined as those academic departments directly overseen by Chairs of psychiatry at United States medical schools, are central organizations to the functioning of U.S. psychiatry. Psychiatry departments oversee the basic science training in behavioral sciences of all U.S. medical students, either in full or large measure. In addition to traditional courses in human development and psychopathology, many psychiatry departments play active roles in teaching topics as diverse as neuroscience, pharmacology, and doctor—patient skills such as interviewing. Psychiatry is one of six core clinical disciplines, including surgery, medicine, pediatrics, obstetrics-gynecology, in which clinical clerkships are mandated by the accrediting body for U.S. medical schools, the Liaison Committee on Medical Education (LCME); without a coherent and effective psychiatry program, the accreditation of a U.S. medical school may be put at risk. Core clinical clerkships in psychiatry are also mandated by most state licensing boards in the United States and are often required to be taken in hospitals that have psychiatry residency programs.
