The SIS Swiss International Schools place their educational focus on bilingualism. By following the very successful immersion method, which invites children to dive headfirst into the foreign language, students learn a second language in a playful and completely natural way. They are immersed in an environment where only the foreign language is used. All teachers are generally native speakers and support their students from kindergarten to primary and secondary school. The very first SIS school was founded in Basel back in 1999. The concept of this bilingual school proved to be extremely successful, resulting in the founding of 16 SIS all-day schools in Switzerland, Brazil and Germany. Currently more than 3,600 local and international students enjoy a bilingual education at SIS schools.
