Curriculum and academics

Mosaic International School is built around genuine bilingual immersion. Since 2004 the school has taught its programme in both French and English, with children spending time in each language across the week rather than treating one as a foreign language lesson. The academic content draws on the Swiss Plan d’études romand, the framework used in the canton of Geneva, combined with the Cambridge International and English national curriculum, so that pupils build skills recognised in both the local Swiss and the international systems. Families comparing dual language options can read our guide to bilingual schools.

The school has historically focused on the early years and primary stage, ending at around age 13, and from August 2026 it is adding a bilingual middle school that follows the local Swiss curriculum with an enriched programme intended to open the way to a range of local and international routes for further study. It does not currently offer the IB Diploma, so families looking for a through school to age 18 should plan the move to a secondary school as part of their decision. Ask about the new middle school places and onward pathways during admissions.

Mosaic International School fees

Mosaic International School is a private bilingual day school and sits in the lower to middle band of the Geneva market for primary age children, below the large international through schools mapped in our Geneva school fees guide. The school publishes tuition by year group, so check the schedule for the stage your child will enter, and note that the new middle school may carry a different rate.

Plan for the costs that sit above tuition. These usually include a registration or application charge on entry, with further line items for lunch, activities and clubs, trips and outings, and materials. As a smaller school, Mosaic keeps its fee structure simpler than the large campuses, but confirm the current schedule and exactly what is included directly with the school.

Admissions and intake

Mosaic International School runs an academic year from late August and admits across the primary year groups subject to availability, with the early years the natural entry point and the new bilingual middle school opening from August 2026. As a small school, places in some year groups can be limited, so register early once a move to Geneva is confirmed.

Admission is based on prior school reports where a child has attended before, age appropriate observation for the youngest children, and a review of readiness for the bilingual programme, although immersion is designed to bring in children who do not yet speak both languages. Applications are made through the school and require passport documentation and any recent reports.

Location and who goes there

The school is in Champel, a residential district on the left bank of Geneva close to the city centre and the university hospital, an area popular with local and expatriate families. Because it is a day school rooted in the city, its community is drawn largely from Champel and the surrounding left bank neighbourhoods rather than from boarding, which gives it a local, neighbourhood feel.
