In Brief
If you want bilingual English-French primary education in a manageable, neighbourhood school rather than an institution, and you are based on the left bank, Ecole Mosaic is worth a serious look. The ISP network brings resources a school of 280 would not normally have access to; just budget honestly for the language tutoring surcharge if your child is not already bilingual.
Ecole Mosaic occupies a specific and practical niche in the Geneva primary market. It is a bilingual English-French school in Champel - one of Geneva's more sought-after residential neighbourhoods on the left bank - running the Swiss PER curriculum alongside the English National Curriculum for children aged 3 to 13. Around 280 students attend, average class size is 17, and the school is part of the International Schools Partnership (ISP) global network, the same group that owns the British School of Geneva. ISP membership gives Mosaic access to collaborative STEAM programmes, a robotics lab, recording studio, music and theatre provision that a stand-alone school of this size could not sustain independently. A Middle School opened in 2024, extending the age range from 12 to 13.
The pedagogy is project-based rather than traditionally structured - families who have been through more formal French or Swiss state schools tend to notice the difference quickly. Teachers are described as accessible and genuinely invested in individual children, and the school's iSchoolAdvisor rating sits at 4.3 out of 5. One thing worth understanding before applying: children without a bilingual background - those not already comfortable in both English and French - are enrolled in compulsory language tutoring, which adds 15-40% to the annual fee depending on intensity. For a child starting from scratch in one language, that surcharge is not optional, so it needs to be factored into the full cost comparison at the outset.
The honest trade-off at Mosaic is the age ceiling. At 13, children leave for secondary - either back into the Swiss state system, into the French Bac track at a school such as Topffer or Florimont, or into the British or IB stream elsewhere in Geneva. That transition requires planning and sometimes a language shift, particularly if the child has been in English-dominant classes. Families who plan to stay in Geneva long-term should map the secondary pathway before they commit at primary level. The school has a bus service and a canteen. Registration carries a one-time fee of CHF 1,990 (CHF 1,490 for a second child), and there is a 20% discount from the third child.
What parents value
- –Bilingual English-French primary in Champel - one of the most convenient left-bank locations of any bilingual school in this guide, and genuinely accessible for families in the Champel-Eaux-Vives-Carouge arc.
- –ISP network access brings STEAM, robotics, music and theatre programming to a school of 280 students - a level of co-curricular provision that significantly exceeds what a comparable independent school would offer.
- –Average class size of 17 and consistent parent feedback on teacher accessibility and pastoral engagement. The school feels like a community, not a processing centre.
Points of consideration
- –Language tutoring surcharge of 15-40% applies to children without a bilingual background. For a child starting French or English from scratch, the real annual cost is meaningfully higher than the headline fee. Calculate this before comparing with other schools.
- –School stops at age 13. Secondary planning starts earlier than at most Geneva schools - map your child's likely route before committing at Early Years level.
- –ISP group ownership means some decisions sit above local management. Ask about the stability of the current Director General and what has changed in the past two years.
