Founded in 1924, the International School of Geneva opened on 17 September with eight students and a rabbit, established by local educators and officials from the League of Nations and the ILO to provide international education based on the éducation nouvelle movement. In 1929 the school moved to La Grande Boissière and Marie-Thérèse Maurette became director. By 1958 the student body reached 1,000, and in 1968 the Foundation of Ecolint was formed and the English-French IB Diploma Programme began. In 1974 the school merged with Lycée des Nations - Collège International de la Châtaigneraie creating the La Châtaigneraie campus, and in 1975 merged with the United Nations Primary School. Campus des Nations opened in 2005 and leadership continued with Conrad Hughes becoming Director General in 2023; the centenary was celebrated in September 2024.
Community Life encompasses events spanning sports, humanitarian projects and musical activities across three campuses. Each campus hosts a vibrant Parent Teacher Association (PTA) that collaborates with campus leadership to strengthen community ties and facilitate communication between families and the school. PTA activities foster engagement and support school projects through fundraising and volunteer involvement.
PTAs are independent bodies that work closely with campus leadership to build community spirit, encourage communication between the school and parents, organize family activities and raise funds for community projects. They also provide a support system for families new to the school. Activities include the annual Kermesse (international fair), winter markets, food festivals and seasonal parties, along with information sessions on technology in the classroom, the sports programmes and summer camps.
