The question is not which school is best, but which fits your situation. Three things decide it almost every time: how long you are staying, how old the child is, and which qualification they will need to show afterwards.
A two or three year posting with a planned return home argues for continuity in the national curriculum: the French baccalauréat, the German Abitur, British A-levels, an American High School Diploma. A programme broken off at the wrong moment costs the child a year.
A long-term move argues the opposite way. Children pick up the language quickly at that age, the state school is free and good, and the child's social world is built in their own municipality rather than in an expatriate community that turns over every three years.
Below eight or nine, immersion in a state school works remarkably well, all the more so because every canton runs reception schemes for pupils who do not yet speak the language. After twelve the stakes change: entry into lower secondary involves selection, and a pupil discovering the language of instruction at the very moment they are being streamed starts at a real disadvantage.
In the canton of Vaud, for instance, a pupil arriving in years 9 to 11 who wants the pre-gymnasium track must sit an entrance examination held in late April or early May. Failing it means placement in the general track.
This is the most technical point, and the most widely misunderstood.
A Swiss private school does not automatically award the Swiss Matura. To do so, its programme must obtain federal recognition from the Swiss Maturity Commission, and the application must go through the canton — a private school is not permitted to approach that authority directly. Since the new rules took effect on 1 August 2024, cantons must moreover resubmit programmes that were already recognised.
A pupil at a private school without that recognition can still obtain the Matura, but by another route: the Swiss Federal Maturity Examination, run by SERI with two sessions a year. It is a demanding path, and better known about before enrolment than after.
The question to put to any private school before signing: is your Matura programme federally recognised, and since when? The answer should be verifiable.
Every private school taking pupils of compulsory school age must be authorised by its canton. In Geneva the authorisation is issued by the private education authorisation and supervision service; in Vaud the department authorises both the running of the school and the teaching; in Zurich authorisation rests with the Volksschulamt, and teachers themselves need a teaching permit.
But authorisation is not recognition. The canton of Geneva says so itself, for families' benefit: most private establishments receive no subsidy and no recognition from the canton or the Confederation, and operate as commercial businesses. A school can therefore be entirely in order and award no recognised qualification at all.
The phrase has no legal standing. In practice it denotes private schools teaching in English and preparing an international or foreign qualification — the International Baccalaureate, British IGCSEs and A-levels, the American High School Diploma, the French baccalauréat, the Italian maturità.
That is the most useful filter for a family arriving from abroad: search by qualification, not by label. A school preparing the French baccalauréat matters if you are returning to France; the International Baccalaureate matters if you do not yet know where you will be in five years.
