In brief
A 1903-founded private school in Grand-Lancy with around 1,500 students, running parallel French and English sections plus a bilingual stream all the way through to the IB Diploma and French Baccalauréat.
Originally Collège Marie-Thérèse, IIL is now a non-profit association covering ages 3 to 19 on a leafy campus that mixes heritage and contemporary buildings. Programmes include the IGCSE, IB Diploma, Brevet and French Baccalauréat. NEASC accredited. Many teachers are English mother tongue or bilingual, which families with English-speaking children rate highly. Monique Roiné leads the school. Day school only, no boarding.
Families describe a genuinely international community and small enough class sizes that teachers can give individual attention. The strongest reviews mention dedicated teachers who follow up by email and unusual learning experiences such as river-based geography and outdoor science. The weaker signal centres on management and behaviour processes, with some parents reporting opaque decision-making and inconsistent handling of disciplinary matters. Communication between sections varies. Fees of CHF 18,820 to 30,390 land in the middle of Geneva's private market.

Reviews
- Geneva day school routinely named with Florimont and Collège du Léman as one of the established private options for families who want both French and English-medium tracks.
- Parents praise small classes, warmth in early years ("the warmest you'd meet" said one parent of the reception and nursery teachers), and dual access to the IB and UK A-levels.
- IB Diploma preparation is described as strong, though several parents say the academic load can be heavy for less academic children.
- Two families reported serious bullying that prompted them to remove their children, and other posters flag concerns about management responsiveness and the behaviour system.
- Commute is a recurring caveat: one Geneva parent estimated 45 minutes each way for primary-age pupils living off the south shore, against 5 to 10 minutes to a local school.
- Same SEN access issue noted at Florimont: one family reported IIL among Geneva private schools that declined a 9-year-old autistic child.
