A Growing, International Network of Bilingual Schools

Our Educational Concept

Our Students and Their Learning Needs Are at the Heart of Our Efforts

Our educational concept lies at the heart of our social, pedagogical, didactical and entrepreneurial approach. But every concept is only as good as its implementation in everyday school life – that is why we make it our highest priority to live by it on a daily basis. Our students and their learning needs are at the heart of our efforts. This is put into practice by taking into account the following eight aspects:

  • Bilingual Experience

English and the national language 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 Approach

The teaching philosophy at SIS Swiss International School is not ideological but instead founded on clearly defined core values. We strive to embody the values we seek to impart to our students: honesty, appreciation, personal responsibility and commitment.

  • Day School Community

Our day school offers a structured and challenging programme of classroom instruction with fixed hours, lunch, supervised homework hours and additional flexible supervised periods and courses.

  • Performance through Diversity

Our varied, stimulating environment supports students in achieving excellent academic performance while allowing them to take enjoyment and pride in what they learn. Our international student body combined with teachers hailing from diverse backgrounds result in a diversified range of teaching and learning methods applied to the learning process.

  • 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. At the same time, they have the opportunity to complete the International Baccalaureate Diploma Programme (IBDP), which results in a globally recognised university entrance qualification.

  • Continuity from Kindergarten to College

SIS Swiss International School offers a single unified learning concept – from kindergarten through primary and secondary school to college. Because we cater to all education levels, we can facilitate a seamless transition from one stage to the next.

  • 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 area since 1999. At present, more than 5.000 students attend SIS schools at one of our 17 locations in Switzerland, Germany and Brazil. Our international organisation provides teachers and students with a platform to exchange experiences and insights across national borders.



All SIS schools are approved or recognised by the local educational authorities and are firm fixtures in their area's school landscape. At the same time, our schools are part of a growing SIS network. Currently, more than 5.000 students from both local and internationally mobile families attend classes at one of the 17 schools in Switzerland, Germany or Brazil.


SIS is a company of the Kalaidos Swiss Education Group which belongs to the Klett Group Germany.

Together, as a school group, we empower change for sustainable living.


As an educational institution, we are aware of our responsibility when it comes to sustainability. The impact of SIS Swiss International Schools extends beyond just their operational aspects; it also encompasses what and how we teach in SIS schools, ultimately influencing future generations.


Thus, the national companies of SIS Group strategically approach sustainability from two core directions. Firstly, they diligently assess and work to reduce our CO2 emissions with the ultimate goal to become climate neutral. Secondly, within our educational framework, we strive to promote a sustainable mindset that includes social, environmental, cultural, and economic factors.
