Curriculum and academics
IIL teaches across three language streams. The French stream follows the local francophone route, the English stream was built up after the school created an English language primary section in 2001 and a secondary section in 2005, and a bilingual track lets students work across both languages. In the upper school the International Baccalaureate Diploma sits alongside the French language routes, giving families a choice between a globally portable qualification and a national one without changing school. The school has been an authorised IB World School since 2007.
Because it pairs a French heritage with a developed English and IB offer, IIL suits families moving between French speaking and English speaking systems, as well as long term residents who want their child fluent in both languages. It is one of several Diploma providers tracked in our Geneva IB schools hub, and parents weighing the international route can read our overview of the IB curriculum before deciding which stream fits their child.

Institut International de Lancy fees
Institut International de Lancy sits in the established private band of the Geneva market. Fees are quoted in Swiss francs and rise through the year groups towards the upper secondary diplomas, landing within the range mapped in our Geneva school fees guide. We do not republish a precise figure here because the schedule changes each year, so confirm the current rate with the school before you budget.
Plan for the costs that sit above headline tuition. Expect a registration or application charge, a deposit on acceptance, lunch and after school provision, and examination entry fees in the Diploma years. Transport and the strength of the Swiss franc add to the real cost for a relocating family, so build the full total into any relocation package discussion rather than the headline tuition alone.
Admissions and intake
IIL runs an academic year from August to June and admits across year groups subject to availability, with the early years and the start of secondary among the natural entry points and rolling international arrivals through the year. Places in popular streams can be limited, so register as soon as a move to the region is confirmed.
Admission is based on prior school reports, an age appropriate assessment and an evaluation of which language stream best fits a child. Applications are made through the school and require recent reports, passport documentation and, for transfers, a leaving record. Children with little French can usually enter the English stream and build the second language over time, which makes the school accessible to families arriving from English language systems.
Location and who goes there
The school is on Avenue Eugene-Lance in Grand-Lancy, a residential commune on the left bank southwest of central Geneva and within easy reach of both the city and the airport. Many IIL families live in the left bank communes of Lancy, Carouge and Plan-les-Ouates, with the wider parent body reflecting the international organisations, banks and multinational employers that bring families to the canton. The mix of more than ninety nationalities is a defining feature of the school community.
