Collège du Léman

Collège du Léman, founded in 1960 in Versoix on the shores of Lake Geneva, is one of Switzerland's largest international schools, with roughly 1,900 students representing more than 100 nationalities. It operates as a co-educational day and boarding school across ages 2 to 18, with boarding available from age 10. Since 2015 it has been part of Nord Anglia Education, a for-profit international schools group.

Its defining feature is genuine curricular breadth. The lower years follow a bilingual English/French model, and the High School offers five exit pathways: the IB Diploma Programme, the IB Career-related Programme, the American High School Diploma, the French Baccalauréat and the Swiss Maturité. A British strand is also present, with students prepared for IGCSE and GCE A-Level examinations. This lets families match a leaving qualification to their next destination rather than commit to a single system.

External recognition is strong: the school is accredited by both the Council of International Schools and the New England Association of Schools and Colleges, and is an IB World School authorized for the Diploma Programme (since 2005) and the Career-related Programme (since 2016). No state-graded inspection rating is published — international schools in Geneva are not graded by a Swiss state inspectorate — so the accreditation stack, rather than a public graded report, is the primary quality assurance.

Fees are high. Published 2026-27 day fees run from CHF 24,900 to CHF 37,500, and full-year boarding is CHF 117,500, with boarders paying both day and boarding charges and exam fees invoiced separately. The trade-offs are scale and corporate-group ownership: the school is large and complex, and Nord Anglia's commercial priorities sit alongside school-level decisions.
