The International School of Brussels opened in October 1951 as the American School of Brussels with four teachers and twenty-seven students between the ages of 5 and 11. It was first founded to accommodate U.S. Department of Defense military personnel and their families living in Brussels.[2] It was located in the Brussels commune of Woluwe-Saint-Pierre.[2]

By the end of the 1953 term, the school was home to about 100 students and had moved to its current location at the Château des Fougères, in the Brussels commune of Watermael-Boitsfort. It changed its name from the American School of Brussels to the International School of Brussels.[3]

In 1966, a new High School was opened, however it later became the Middle School building. In 1967, the currently used Elementary School was opened.

In its early years, the entire school was housed in the old Château des Fougères. ISB became an International Baccalaureate school on 1 January 1977 making it the 50th IB school worldwide.[4] Additionally, the first International Festival was hosted in 1977, a festival which celebrates different cultures in the school.[2]

In February 2006, the school board opted to begin fundraising because it determined that the tuition charged to its students was insufficient for its needs.[5]
