SIS Swiss International School Männedorf-Zürich is a private bilingual day school on the Seestrasse in Männedorf, on the right bank of Lake Zürich. It takes children from age four to the end of primary school: a kindergarten for ages four to six, then primary school from age six. German and English are both languages of instruction throughout, used across the curriculum rather than taught only as subjects. Around 100 students attend. The school opened in 2009 and is one of seven SIS campuses in Switzerland.
