Welcome to the International School of Geneva

A not-for-profit foundation established in 1924, Ecolint is, with its 4,400 students, the oldest and largest international school in the world.

Each student is welcomed to the school with a respect for their personal and cultural identity and is offered an international education which allows them to develop their abilities to their highest potential.

We offer our students a high quality bilingual education and we encourage respect, mutual understanding and their engagement as active world citizens.

It is with great pride that we are celebrating this year the 90th anniversary of our school and we look forward to sharing our programme of activities with you throughout the year.
