Upper School Principal
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.
You are unique, with your own strengths, interests, and sense of purpose. That’s why we work with you to chart your own learning journey so you can make the most of the wide variety of academic and co-curricular options available at ZIS.
At ZIS, we allow you the freedom to choose your learning path. Our rigorous curriculum is respected by the world’s top universities, but the details are up to you. You can choose International Baccalaureate, Advanced Placement, or one of our ZIS-developed courses. We give you the opportunity to choose how to make yourself shine brightest.
We develop our Grade 9 and 10 courses to align with international benchmarks. In Grades 11 and 12 you can choose from:
- International Baccalaureate courses including the diploma and bilingual diploma
