Upper School (ages 14-18)

ZIS provides the challenge and support to ensure you become your best self and reach your potential, whatever your interest or passion.

At ZIS, we see each student as an individual, with their own unique interests, strengths and capabilities. We also believe that students benefit enormously from being able to chart their own individual learning journey. This is why we do everything we can to help you make the most of the extensive options available.

We encourage our students to stretch themselves academically, while also stressing the importance of good character, care for others and leadership. We as a community have risen to the challenges of the time and shown great creativity and flexibility as we challenge our students to be resilient, open-minded and compassionate global citizens.
