One school for the whole journey, no transitions to manage. ISZN takes children from Nursery at 3 months through to A-Levels at 18, combining the structure of the British curriculum with a caring international environment</cite>. For a family that's already moved once to get to Switzerland, not having to research and re-apply to a new school every few years is a real relief.
A dual-language start, even inside a British system. Early Years benefit from a dual-language English/German foundation through Kindergarten 1, so children arriving with little or no German still get structured exposure to it before lessons move fully into English.
Genuinely small classes. With an average of 15 students per class, teachers know each learner personally, and lessons are dynamic enough that individual progress stays visible, which is a common frustration parents cite about larger local Sekundarschule classes.
Exam results that back up the pathway. In the 2026 cohort, IGCSE students achieved a 100% pass rate across nine subjects, with 83% of grades landing in the top C-to-A* range and 65% of students achieving seven or more passes at that level; 63% of German entries earned the top A/A* equivalent grades. The A-Level cohort achieved 48% of all grades at A or A*.
A campus built around convenience for working parents. Located just four minutes from Wallisellen station, the campus combines modern facilities with a full-day structure supporting busy families with reliable routines. Specialist science labs, performing arts spaces, a play hall, libraries, digital learning facilities, a gym and access to sports facilities are all on site.
Confirmed by the families already there. One ISZN parent says they've recommended the school to several friends and expats arriving in Switzerland, and appreciates the ongoing support the school has provided.
If you're deciding between staying in the local Sekundarschule system and moving to a fully British pathway, the clearest next step is seeing a real lesson in session. Book a private tour and ask to see a class at your child's current age group.
