SIS Winterthur

School premises reminiscent of the industrial heyday – internationality in a trendy business area.

Welcome to SIS Winterthur! Once the international production site of turbines, pumps and steel for the famous Sulzer company, the same premises are now home to our state-of-the-art schoolhouse. In this place of energy, children grow up to become bilingual, open-minded and committed global citizens. Learning both German and English at a young age, and with equal pedagogical consistency, is a gift that lasts for a lifetime.

Dear visitors,

SIS Winterthur has been successfully implementing the bilingual educational concept since 2001. 

Our kindergarten-to-grade 6 day school community is conveniently located in the heart of Winterthur. Our kindergarten is open to children from 3 to 6 years of age. The school is within walking distance to the historic city centre, forests and gardens, which offers students plentiful opportunities for class excursions.

The two school languages, German and English, act as a bridge connecting the many nationalities under our roof. We strengthen our close-knit community with a variety of school traditions: a buddy system, school assemblies, theme weeks, reading marathons, a recycling programme, sports days, a year-end party and an Advent celebration, among other local and international holidays.

Goal-orientated and differentiated lessons prepare our students for the diverse pathways available to them after primary school.

Our focus on academic achievement, coupled with a strong emphasis on overall student well-being, is what makes our bilingual learning environment at SIS Winterthur unique.

I look forward to welcoming you at our school for a personal tour.
