Ecole des Nations

Geneva's longest-running Montessori school, founded in 1989 in Petit-Saconnex, taking children from age 3 to 12 in a bilingual French-English programme.

The school is small, around 90 children, in a quiet residential street with parks nearby. AMS-accredited and affiliated with the Romandie Montessori association, it follows AMI-aligned classroom practice with mixed-age groups and trained guides.

Families describe a family-scale environment with motivated teachers who build close relationships with individual children. The peace-education thread runs through how the school talks about itself and how parents talk about it. Fees of around CHF 22,000 are flat across ages. The natural exit is at 12, and parents need a clear plan for secondary, typically into one of the larger international schools or into the Swiss public system.

• A small and tightly positive review pool, all framed around fidelity to the Montessori method. Parents describe motivated, kind, professional teachers who "listened to children and established durable connections with them".
• One parent said the school helped their child develop "amazing creativity, curiosity and impressive problem solving" over five years, crediting the Montessori approach.
• Reviewers consistently flag the family-feel scale: a small school in a quiet street near parkland in Petit-Saconnex, which several treat as part of the substance, not the marketing.
• Bilingual French-English instruction and Cambridge exam preparation are repeatedly cited; peace education and respect-based culture are also called out.
• Pool is small (around five reviews on the main aggregator). The absence of negative signal is genuine but the pool is not large enough to stress test consistency across cohorts.
