International School of Geneva

The International School of Geneva , also known as "Ecolint" or "The International School", is a private international school based in Geneva, Switzerland. Founded in 1924 in the service of the League of Nations, it is the oldest and largest operating international school in the world. In the mid-1960s, a group of teachers from Ecolint created the International Schools Examinations Syndicate , which later became the International Baccalaureate Organization and then the International Baccalaureate .
Ecolint is composed of three campuses in and around Geneva, each with its own principal working under the Director General of the Foundation of the International School of Geneva and a Governing Board elected by parents and staff with co-opted members from the UN and Swiss Government. Ecolint is a bilingual school, with instruction primarily in English and French. In addition to the IB, it is a testing centre for the US college boards and the British IGCSE .
