How many international secondary schools in Zurich
Zurich Canton hosts around ten international secondary schools delivering instruction predominantly in English. The cluster splits between full continuum providers such as Zurich International School, Inter-Community School Zurich, SIS Zurich and ISZN, plus the Zug border boarding settings such as Institut Montana Zugerberg and Lyceum Alpinum Zuoz that draw a meaningful share of Zurich families.
Year group sizes are smaller than at large international hubs. A typical Year 7 to 11 cohort in Zurich runs to 60 to 90 pupils across three or four form groups. Sixth form cohorts are smaller still, usually 50 to 80 pupils for IB Diploma and 30 to 50 for A-level or US High School Diploma. The smaller scale gives strong attention but limits Higher Level subject availability and constrains the team sports calendar.
The cluster is mature. All major providers have run secondary in Zurich for at least fifteen years, with three running for more than fifty. Cantonal authorities recognise both the IB Diploma and the Swiss Matura for direct entry to Swiss federal universities. A-level recognition for ETH and University of Zurich is straightforward provided AAB or higher is achieved including mathematics where required.
Fees and tiers
Secondary tuition in Zurich sits within three rough tiers. The value tier, CHF 32,000 to CHF 36,000 a year, covers smaller secondary providers and the lower senior years at the largest schools. The mid tier, CHF 37,000 to CHF 42,000, captures the principal years at ZIS Upper School, ICS Zurich and SIS Zurich senior school. The premium tier, CHF 43,000 to CHF 48,000, applies to sixth form years at the most established schools.
Capital contributions are common at Zurich secondary schools, typically a one-off CHF 8,000 to CHF 15,000 at enrolment. Sixth form charges include IB or A-level examination registration of CHF 1,200 to CHF 2,200 a year. Add 8 to 12 percent of tuition for trips, instrument hire and material fees.

Sixth form pathways: IB, A-level and Matura
Sixth form choice in Zurich runs across four pathways. The IB Diploma is offered at ZIS Upper School, ICS Zurich, ISZN and Institut Montana, with the highest enrolment at ZIS and ICS. A-levels are offered at ISZN through a Cambridge International programme. The US High School Diploma is offered at ZIS Upper School as an alternative to the IB Diploma. The Swiss Matura is delivered in bilingual form at SIS Zurich.
For university entry, the IB Diploma performs strongly across UK, US and Swiss admissions, but Swiss federal universities prefer either the Matura or the IB Diploma with German A. A-level pupils targeting ETH or University of Zurich should plan a one-year bridging Matura or take German as a fourth A-level subject. Our IB curriculum guide covers the global Diploma picture in more detail.
Illustrative example schools
The five secondary schools below are illustrative, not a ranking. Each runs a senior school of at least Year 7 through 13 with a published university outcomes record.
Zurich International School Upper School (Adliswil). The flagship international secondary in the canton with IB Diploma and US High School Diploma pathways. Strong destinations across US and UK universities.
Inter-Community School Zurich (Zumikon). Full continuum IB Middle Years and Diploma with bilingual stream options at primary. On the Gold Coast above the lake.
International School of Zurich North (Wallisellen). English National Curriculum through IGCSE and Cambridge A-level. Convenient for families based in the northern suburbs and around Zurich Airport.
SIS Swiss International School Zurich (Wollishofen). Bilingual Matura and IB Diploma pathways. The natural choice for families committing to a longer Swiss stay with one Swiss parent.
Institut Montana Zugerberg (Zug). A short cantonal hop south. Full boarding and day pupils with IB Diploma and Swiss Matura. Strong sports and outdoor programme.
Where secondary families live
International secondary families in Zurich cluster around four catchments. The Gold Coast above the lake, covering Kusnacht, Zumikon and Erlenbach, holds ICS Zurich and is popular with senior management families. The lake south shore, covering Adliswil, Kilchberg and Wadenswil, is dominated by ZIS Upper School. Central districts such as Enge, Wiedikon and Seefeld suit families using SIS Zurich senior school.
The northern suburbs around Wallisellen, Opfikon and Glattbrugg serve ISZN and offer shorter commutes for families with one parent at Zurich Airport or the major insurance and pharmaceutical hubs. Pupils travel independently from age 11 onward by SBB train and tram, and most schools sit within 30 minutes of central Zurich.
Admissions calendar
Most Zurich international secondary schools open the main August intake window in October of the previous year and close priority deadlines by late January. Mid-year transfers in Years 7 through 9 are common where places exist. Year 10 transfers are possible but require GCSE or IGCSE subject alignment.
Sixth form transfers are accepted before October of Year 12 for IB Diploma and before September of Year 12 for A-level. After those dates, schools usually decline transfers because Internal Assessment work and Cambridge coursework are already underway. Assessment for Years 9 through 11 typically covers English, mathematics and one other subject; sixth form assessment usually includes a subject interview. Capital contributions and IB or A-level registration fees are payable on acceptance.
