The school was founded in August 1984 by a decree of
King Fahd and originally served grades K–6. The Saudi government purchased the 34-acre campus of the former Fairfax Christian School in Fairfax from owner
Robert L. Thoburn for $3 million as a site for the school. Following the leasing of the Dunn Loring site, the school expanded its education program to include grades 7–12. When the lease on the Dunn Loring site expired, the school leased the former
Mount Vernon High School in
Mount Vernon, Virginia, near
Alexandria, spending $5 million to renovate the nearly 50-year-old building. The academy moved into the Alexandria site in 1989. For much of its history it maintained two campuses: the main campus near Alexandria and the West Campus in
Fairfax Station, near
Fairfax. In December 2015 there were plans for the school to move to a new campus near
Herndon. The original ISA closed in June 2016, and the new King Abdullah Academy near Herndon opened in Fall 2016.
King Abdullah Academy King Abdullah Academy, or KAA, opened in fall 2016 under the direction of the Saudi Arabian Cultural Mission to the United States. Its goal was to provide a U.S.-based, English-language curriculum rooted in Islamic values and Arabic language instruction. It primarily served children of Saudi diplomats and expatriates residing in the greater Washington, D.C. area. The school was built on a 40-acre campus previously zoned for educational use. As such, no additional hearings were required by the
Fairfax County Board of Supervisors. At the time of planning, Supervisor
Michael R. Frey reported no public opposition to the site. Located near
Washington Dulles International Airport, the King Abdullah Academy campus featured modern academic buildings, a soccer field, walking trails, outdoor classrooms, and an Olympic-style swimming pool. The school was purpose-built with security and architectural standards similar to those used for diplomatic and international facilities. KAA offered instruction in English, Arabic, and Islamic studies. The lower school (K–5) was co-educational, while middle and high school students were taught in gender-segregated classes. In January 2025, the school announced that it would close permanently at the end of the 2024–2025 academic year due to financial and administrative sustainability concerns. According to a letter from the board, the school had been unable to establish a viable long-term funding model to maintain operations independently of Saudi governmental support. The closure affected approximately 450 students and 160 staff members. Legal proceedings were initiated to investigate potential violations of the federal
WARN Act, as employees were allegedly notified with fewer than 67 days' notice. In June of 2025 it was announced that
Fairfax County Public Schools in Virginia would purchase the campus, buildings, and equipment for $150 million with the intention of opening a new public high school for the county. ==Programs and activities==
