Classrooms Without Walls

ZIS believes that cultural excursions and school trips represent excellent learning opportunities. All Upper School students participate in mandatory Classrooms Without Walls (CWW) trips which are directly related to our Mission and Philosophy - Learn, Care, Challenge, Lead.  Most trips are covered by tuition fees (except for trips such as Ghana, Nepal, Tanzania and Sri Lanka for which a co-payment is required). CWW Trips are usually 5 days in length and take place in June each 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.
