The Admiralty Interview Board (AIB) is an assessment centre, tracing its roots to 1903, that is used by the Naval Service as part of the officer selection process for the Royal Navy, Royal Marines, Royal Naval Reserve, Royal Marines Reserve, and Royal Fleet Auxiliary. It is an equivalent of the Army Officer Selection Board and the Officer and Aircrew Selection Centre of the Royal Air Force. The board is based at HMS Sultan in Gosport, Hampshire, within a self-contained compound.
