ZIS Overview

At Zurich International School, we provide an education that ensures children develop a lifelong love of learning. 

Our students learn in a multicultural community where each person is respected. Students discover the world, its people, and its cultures through direct experience. Through play, study, and the relationships they form, students at ZIS learn to appreciate their own strengths and to respect differences rather than fear them.

Combined with academic rigor, this experience extends outside the classroom and equips students for success and global citizenship beyond school.
