Overview

Zurich International School (ZIS) is a leading, non-profit day school offering a comprehensive education program for students, both local and expat, aged 3 to 18 in the greater Zurich area. There is an additional bilingual pathway for students aged 3 to 9
ZIS understands that education is about finding the right balance. Our goal is to ensure that every child leaves with a love of learning. So we give them a safe environment to explore without fear of failure. Our rigorous curriculum – including the International Baccalaureate Diploma Programme (IB) and Advanced Placement courses (AP) – provides a foundation that helps students reach the most prestigious universities. But it also prepares them for a future that requires compassion, leadership, adaptability, resilience and original thinking.

At ZIS, we encourage students to discover new ideas and possibilities, and learn by trying and doing. Children are inspired to go further but to take their own path. That means that what they learn will be transferable and transformative.

Every student explores a wide range of extracurricular activities, from arts to sports, from debating to journalism. We encourage students to try new things so that they can discover who they really want to be. We work to create an environment in which students can be adventurous because they feel supported. We challenge each child to excel, but to protect their mental health and look out for others.

ZIS is truly international, with our 1,300 students representing over 70 nationalities and speaking 40 mother-tongue languages.

ZIS is made up of a Lower School for students aged 3 to 11 in Wadenswil and a Secondary Campus for students aged 11 to 18 in Adliswil.

ZIS, the longest accredited international school in Switzerland, is an International Baccalaureate (IB) Organisation World School, is accredited by the New England Association of Schools and Colleges (NEASC) Commission on International Education and is approved by the Department of Education of the Canton of Zurich.
Learn, Care, Challenge, Lead are the cornerstones of our mission.
