When the lease on the Dunn Loring site expired, the school leased the former Mount Vernon High School in Mount Vernon, Virginia, near Alexandria,[9][10] spending $5 million to renovate the nearly 50-year-old building.[11][12] The academy moved into the Alexandria site in 1989.[13] For much of its history it maintained two campuses: the main campus near Alexandria and the West Campus in Fairfax Station, near Fairfax.[14][15]
