Brussels American School (BAS) was opened in October 1967. It is located near Brussels, Belgium on a 17-acre (69,000 m) area in Sterrebeek, part of the municipality of Zaventem. The school serves as a DoDDS private school for all US military or diplomatic dependents. It celebrated its fortieth anniversary in late 2007. It also takes many European students from Partnership for Peace (PfP) countries of NATO, to include Macedonia, Lithuania, Azerbaijan, etc. Its proximity to NATO (North Atlantic Treaty Organization) helps serve as an excellent opportunity for American children to enroll in a school taught to familiarize them with the American school system.
