# International School of Brussels

The International School of Brussels (ISB) is an English-language international school in the Brussels municipality of Watermael-Boitsfort.

## History

ISB was founded in October 1951 as the American School of Brussels, initially to serve U.S. Department of Defense personnel and their families residing in the area. It began with four teachers and 27 students, aged 5 to 11, at a location in Woluwe-Saint-Pierre. By 1953, the school had about 100 students and relocated to the Château des Fougères in Watermael-Boitsfort and adopted its current name.
In 1966, ISB added a high school building, followed by a new elementary school building in 1967. The entire school initially operated within the Château. ISB became the 50th International Baccalaureate school worldwide on January 1, 1977, and hosted its first International Festival the same year.
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. This decision marked a shift towards increased financial planning to support the school's operations and development.

## Leadership

The board of trustees has approximately 18 members and three to four ex-officio members. There are also several honorary trustees, who are all volunteers. To ensure continuity and institutional memory in a population with a 25% turnover each year, the board strives for a balance of long-term and short-term members. Board members are appointed for three-year renewable terms, with a maximum length of service of nine years. Each member serves on one of the standing committees or an ad hoc committee, depending on his or her area of expertise. The Board is responsible for setting the school's strategy and is the guardian of the school's mission. This includes holding the school accountable for delivering on all aspects of the mission, verifying that the school operates on a sound financial basis, and taking all necessary steps to ensure the long-term success of the school.

## Extracurricular activities

ISB offers extensive extracurricular programs, including:
* Athletics: Sports such as basketball, cross country, football, volleyball, field hockey, and track & field. Notably, ISB is one of the few international schools that offer American football.
* Arts: Music programs, theater productions, and art exhibitions.
* Cultural Events: The annual International Festival celebrates the diverse cultures represented within the school community.
