Bilingual Experience

English and German play equal roles in school communication – in the classroom and in all parts of day-to-day school life. As a result, children learn to express themselves naturally and confidently in both languages.

Independent and Value-Centred

The teaching philosophy at SIS Swiss International School is independent and guided by clear values. We strive to embody the values we seek to impart to our students: integrity, appreciation, responsibility and commitment. 

Day School Community from Kindergarten to College

For our students, school is a place to learn and thrive – an environment that is stable and nurturing while providing appropriate challenges. By learning and playing together, students develop the ability to share with others and build assertiveness.

Performance with Student-Centred Approach

The varied, stimulating environment of SIS Swiss International School supports students in attaining academic excellence while allowing them to take enjoyment and pride in what they learn.

International Education – Local Insight

Our intention is that SIS students graduate as global citizens with a strong sense of their origins. For students at college level, we offer targeted preparation for the national high school diploma (Matura). At the same time, they have the opportunity to complete the International Baccalaureate Diploma Programme (IBDP), which culminates in a globally recognised university entrance qualification.

Global Mindset through Diversity

At SIS Swiss International School, our students develop a global mindset through meaningful interaction with different cultures, perspectives and ways of thinking. Through this, they cultivate empathy, critical thinking and adaptability, broadening their understanding of both local and global contexts.

Learning Enhanced by Technology

At SIS, technology is used in a targeted manner across all subjects, underpinned by a pedagogical concept for learning and teaching. From kindergarten onwards, students explore the areas of digital technology, programming and media as well as communication and e-safety. We use up-to-date, dedicated software to support the learning process of our students.

Strong Network

Our schools are part of the SIS Group, which has been a pioneer in the bilingual education arena since 1999. At present, more than 3.800 students attend SIS schools at one of our 16 locations in Switzerland, Germany and Brazil.
