Public schooling in Switzerland is free, high-quality, and organized cantonally, taught in the local official language (German, French, or Italian depending on canton) — this is the default and by far the most common choice for resident families, including most expats who stay more than a couple of years. For families wanting English-language instruction or continuity with an international curriculum, private international schools are widely available in Zurich, Geneva, Basel, and other major cities, but cost CHF 20,000-40,000+ per child per year.
The choice between free, high-quality but local-language public school and expensive international school is one of the biggest financial and integration decisions a relocating family makes — many long-stay expat families choose public school specifically for language immersion and cost, reserving international school for shorter, career-driven postings.
Key Facts
Public school is free and compulsory from around age 4-6 (kindergarten/primary start varies by canton) through age 15-16, taught in the canton's official language.
Switzerland's PISA rankings and vocational education/apprenticeship system (a well-regarded dual-track path combining school and paid on-the-job training) are internationally recognized strengths.
International schools (offering English-language, IB, or other national curricula) are concentrated in Zurich, Geneva, Basel, Lausanne and Zug, and typically cost CHF 20,000-40,000+ per child per year.
School enrollment is managed at the commune level; families register locally and are typically assigned the nearest public school in their catchment.
The vocational apprenticeship track (about two-thirds of Swiss students) is a genuine, respected alternative to the academic/university track, not a fallback option as it can be perceived elsewhere.
Steps
Decide public vs. international school — Weigh language immersion and cost (public, free) against curriculum continuity and English instruction (international, expensive).
Register with the commune — Public school enrollment is arranged through the local commune based on residential address.
Apply early for international schools — Popular international schools in Zurich/Geneva often have waitlists — apply well ahead of the intended start date.
Assess language support — Ask about language integration classes for non-native speakers if choosing public school without existing language skills.

Common Mistakes
Assuming international school is the default choice — most long-term expat families in Switzerland actually choose free public school for cost and language-immersion benefits.
Applying to a popular international school too late and missing a place for the intended school year.
Underestimating the language transition for children entering public school without prior German/French/Italian — most schools provide support, but it should be planned for.
