Welcome to the Lower School

At ZIS we believe in educating the whole child in innovative ways based upon a caring atmosphere, sound practice and extensive research. Whilst many things change, excellent literacy, numeracy skills and outstanding interpersonal skills are a prerequisite for our children to be successful in the future.

How do we accomplish this?

  • Focusing on reasoning, resilience and responsibility
  • Learning in purpose-built spaces both indoors and outdoors
  • Using real context wherever possible, virtually, in the classroom and on field trips 
  • Valuing all members of our community
    • our cherished students: we create an individual learning path for each one
    • our supportive parents: we view parents as partners in our students' education
    • our outstanding teachers: every year more highly qualified teachers join us

We look forward to working with you to make this year your child’s best year of education yet!

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.
