The Royal Air Force College (RAFC) is the Royal Air Force training and education academy which provides initial training to all RAF personnel who are preparing to be commissioned officers. The College also provides initial training to aircrew cadets and is responsible for all RAF recruiting along with officer and aircrew selection. Originally established as a naval aviation training centre during World War I, the College was established as the world's first air academy in 1919. During World War II, the College was closed and its facilities were used as a flying training school.
