Welcome to the ZIS Lions' Den!

We encourage athletes of all ages to achieve their full potential, and do this through our comprehensive program, excellent facilities and, above all, our dedicated coaching staff. We are committed to a program that encourages a philosophy of "team spirit" and a sense of "fair play" for which we are well-known on the international school circuit. Our athletes travel extensively around Europe and ZIS families host hundreds of visiting athletes each year. In this way our students and their families have the opportunity to participate in a fun and rewarding program, which also promotes their physical, emotional and social well-being.

We participate in two international and one national organizations:

We compete in all three competitions and host a minimum of two ISST, two SCIS and three SGIS tournaments per school year.

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.
