Welcome to the Upper School

Students who attend our Upper School are citizens of the world. It is often said that students at ZIS are allowed to choose their own adventure. Whether undertaking the International Baccalaureate diploma, Advanced Placement courses, or ZIS-developed courses, our outstanding learning environment allows students to:

  • create their own learning pathways
  • pursue their passion
  • undertake experiential learning opportunities in Switzerland and abroad

Have a look at our Upper School Profile to see more about our campus. Better yet - if you are able to come by for a visit, we’d be happy to show you around our community.

All best wishes,

John Switzer, Upper School Principal

About Us

With more than 1,450 students at four unique campuses, ZIS offers an extensive educational program with all the benefits of size but the intimacy of smaller settings.



We know that choosing the right school is one of the most important decisions you can make for your child. Our Admissions Team is here to help and guide you through the process.


Learning at ZIS

At ZIS we recognize the unique and diverse nature of our students. That’s why accommodating the individual learning needs of each and every student remains our highest priority.


Student Life

Co-curricular activities challenge our students’ personal, social and physical development and encourage a greater passion for learning. Opportunities range from the arts to sports to outreach and service work and beyond.



ZIS has four unique campuses offering a personal experience to each of our students. Whether it is an old villa or one of our modern buildings, ZIS offers an age-appropriate environment for your child’s learning.



The ZIS community extends beyond our students and includes ZIS families, alumni, faculty and staff, corporate partners, neighbors and friends.



Once a member of our community, always a part of our family around the world! Our alumni include former students, former parents and former faculty and staff. At ZIS we welcome our alumni’s engagement and strive to help you stay connected with your ZIS.
