Geneva is not a boarding château on a postcard. The day-school conversation starts with the International School of Geneva (Ecolint) — a foundation, ages 3–18, three campuses, and a school that helped invent the IB.
Use the portraits for Swiss-franc fees and which diploma sits where. This note is the city around them. The Switzerland country page is the wider walking map — including Collège Champittet on the Vaud side, Pully and Nyon, a lake door that is not a Geneva campus.
One school, three Tuesdays
Ecolint is not “the lake school.” It is La Grande Boissière, Campus des Nations, and La Châtaigneraie in Founex.
The portrait is specific: Nations holds PYP, MYP, DP and CP. Grande Boissière holds a Universal Learning Programme and the IB DP. Châtaigneraie holds PYP, MYP-aligned middle years, then IGCSE and IB DP or the Swiss maturité fédérale. English and French live on the pages. Ask which campus this child would actually sit on. A brochure that says “Geneva” is not an address.
Time the lake, not the postcard. Grand-Saconnex and Founex are not the same 7:40.
Official doors in the same week
Families who visit Ecolint often also walk Collège du Léman in Versoix — Nord Anglia, day and boarding, five published diplomas — or Institut Florimont in Petit-Lancy, a 1905 privé with Swiss Maturité, French Bac and IB. Collège Champittet is the official Vaud-side door: Pully, optional boarding, Swiss Maturité, French Bac and IB. Time that drive. Those houses share a lake and almost no Monday.
Read each house’s own franc PDF. We printed the 2026–27 tables we could open. Confirm them there.
Boarding is a different Geneva-adjacent childhood. Institut Le Rosey and Aiglon College live on the boarding map, not on this city hub. Go on a Sunday evening if that is the conversation.
French in the yard
Geneva is a French-speaking city. An English-medium classroom does not make the tram English. Ask how much French a shy eleven-year-old will really have by the second spring. Ask who translates the joke in the first month. The language of the yard is that test.
If you might stay, the Swiss maturité and a bilingual private are not optional colour. If you will leave, the portable IB may be the kindness. Write which.
The city hub is the short map. The Ecolint portrait is the long one. Zurich is another Swiss Tuesday; do not flatten it into “near Geneva.”
Friendly orientation, not formal admissions advice. Always confirm dates with the school.
