What's the difference between an international school and a bilingual private school in Switzerland?+
International schools usually offer globally recognised curricula (IB, American, British, French) with a multicultural student body. A bilingual private school may follow the Swiss programme while teaching in two languages. The choice depends on your family's future mobility.
How much does an international school in Geneva or Lausanne cost?+
Expect between CHF 25,000 and CHF 45,000 per year for day tuition at a top international school in French-speaking Switzerland. Premium boarding exceeds CHF 100,000. Some companies cover fees as part of expat packages.
Do you need to speak French to attend an international school in Geneva?+
No. Most international schools teach in English and offer French as a foreign language (FLE). This is often the best choice for a newly arrived English-speaking family. Some schools offer a progressive path toward bilingualism.
When should we apply?+
The best schools have waiting lists. Ideally, start the process 6 to 12 months before the desired start. We can open applications in parallel at several schools matching your child's profile.
