The International School of Brussels (ISB) is an English-language international school with grades spanning from pre-school to high school. Its campus lies in the Brussels commune of Watermael-Boitsfort. History 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 established to accommodate U.S. Department of Defense military personnel and their families living in Brussels. It was located in the Brussels commune of Woluwe-Saint-Pierre. 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. In 1966, a new High School was opened, which however 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. Additionally, the first International Festival was hosted in 1977, a festival which celebrates different cultures in the school. 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. Buildings and campus ISB is located on a wooded campus. Green is the predominant colour on campus. Surrounding the school is a forest, with entries to the Brussels region's forest trails across the campus. An outdoor track, performing arts center, two gymnasiums, and of playing fields and woods are located on the campus. The 19th century building called the "Château" is the school's administration building. Designed with pillars, the building houses a reception area that hosts parents of students.
