How many bilingual schools in Zurich
Zurich Canton currently lists around fourteen schools that publish a formal bilingual programme, almost all combining German and English. A further dozen Tagesschulen and Montessori houses run informal bilingual immersion in the kindergarten and early primary years. The bilingual market is concentrated in three networks: SIS Swiss International School, the bilingual stream at Inter-Community School Zurich, and the independent Montessori houses on the lake.
Class sizes at bilingual schools are smaller than at the large English medium internationals. A typical bilingual primary class in Zurich runs to 16 to 20 pupils, with the most popular providers capping each year at two form groups. That gives parents access to teachers but limits subject breadth in the senior years, where most pupils move to single-language IB or Matura pathways.
The bilingual cluster has matured rapidly since 2018. New campuses have opened in Kilchberg, Wollishofen and Pfaffikon to meet demand from dual-language families. Around 60 percent of pupils hold a Swiss passport plus a second nationality, with the largest groups being Swiss-American, Swiss-British and Swiss-German families. Pure expat enrolment is around 35 percent of the cluster.
Fees and tiers
Bilingual tuition in Zurich sits within three rough tiers. The value tier, CHF 18,000 to CHF 24,000 a year, covers the smaller Montessori and Tagesschule providers. The mid tier, CHF 25,000 to CHF 32,000, captures SIS Zurich primary, Lakeside School and Tandem International Montessori. The premium tier, CHF 33,000 to CHF 38,000, applies to ICS Zurich bilingual stream and the senior years at SIS.
Published tuition is not the all-in cost. Capital contributions are common at the larger providers, typically a one-off CHF 5,000 to CHF 12,000 at enrolment. Add 8 to 12 percent for lunch, transport, school trips and language support. Full year-by-year breakdowns sit in our Zurich fees guide, which also covers Swiss public school comparisons.

Languages and bilingual models
Three bilingual models dominate Zurich. The first is parallel immersion, where pupils spend mornings in German and afternoons in English with separate teachers for each language. SIS Zurich and Obersee Bilingual School follow this model. The second is subject split immersion, where certain subjects such as maths and science are taught in English and others in German. ICS Zurich and Tandem International Montessori use this approach at primary.
The third is one teacher one language, where two teachers share each classroom and consistently use a single language with the pupils. This is rare beyond age 8 because cost makes it impractical to staff. Children moving between Zurich bilingual schools and Swiss public schools generally find the transition manageable from age 9 onward, although families targeting Swiss federal universities should consider switching to a Matura pathway by age 14 to align with cantonal entry expectations.
French is rare in Zurich bilingual schools. Only one provider, the Ecole Mosaic in Kilchberg, runs a formal French English bilingual stream. Families seeking French immersion typically travel cross-canton to the Lycee Francais in Adliswil or relocate to Geneva, which our curriculum overview covers in detail.
Illustrative example schools
The five schools below are illustrative, not a ranking. Each runs a published bilingual programme accepted by Swiss cantonal education authorities and prepares pupils for both German and English medium secondary pathways.
SIS Swiss International School Zurich (Wollishofen). The largest bilingual provider in the canton, running parallel immersion German and English from age 3 through Diploma. Multiple campuses across German speaking Switzerland.
Inter-Community School Zurich (Zumikon). Premium bilingual stream alongside an English medium pathway, with IB Diploma at sixth form. Popular with senior management relocations to the Gold Coast.
Obersee Bilingual School (Pfaffikon SZ). Just outside Zurich Canton on the eastern shore. Parallel immersion through to IB Diploma. Strong choice for families based around Lachen and the Linth corridor.
Tandem International Montessori School (Kusnacht). Bilingual Montessori for ages 3 to 12. The bridge between immersion play based learning and a structured primary pathway.
Lakeside School (Kusnacht). Smaller bilingual primary on the lake shore with a senior school partnership for IB Diploma in nearby Adliswil.
Where bilingual families live
Bilingual families in Zurich cluster around four areas. The Gold Coast above the lake, covering Kusnacht, Zumikon and Erlenbach, holds Tandem Montessori, Lakeside School and ICS Zurich, and suits senior management families in finance and pharmaceuticals. The lake south shore, covering Wollishofen, Kilchberg and Adliswil, holds the SIS Zurich campus and is the natural choice for SIS families with a sub forty minute commute to Paradeplatz.
Central districts such as Enge and Wiedikon work for families with one parent commuting to a city centre office, with multiple smaller bilingual nurseries and Tagesschulen feeding into the larger providers at age 6. The eastern shore around Pfaffikon and Lachen serves Obersee Bilingual School families, and benefits from lower cantonal tax in Schwyz at the cost of a longer commute.
Admissions calendar
Most Zurich bilingual schools open their main August intake window in October of the previous year and close priority deadlines by late January. Mid-year transfers in kindergarten and lower primary are common where places exist. From age 9 onward, transfers are subject to a written German and English assessment plus a head teacher interview to confirm bilingual readiness.
If you are targeting SIS Zurich, ICS Zurich or Obersee, apply nine to twelve months before your desired start. Late applicants are placed on waiting lists with the most movement between May and August as withdrawals come through. Capital contributions are payable on acceptance. For sibling places the cluster generally honours priority where the older child is enrolled.
