Welcome to SIS Swiss International School Winterthur. As a private day school committed to consistent and genuine bilingual classroom instruction, we offer education on all levels from kindergarten through to secondary school and college. Teaching at SIS is based on our established and unified school concept.
SIS operates 17 bilingual day schools in Switzerland, Germany and Brazil. From kindergarten through to secondary and college level, more than 3.800 students from both local and internationally mobile families are educated in English and German.
In Switzerland, we have schools in eight locations. The combination of an international outlook and close ties to the local community empowers our students to take on the challenges of today’s globalised world with confidence.
Our teaching philosophy is non-ideological, but founded on clearly defined core values such as honesty, appreciation, personal responsibility and commitment.
