An AISZ education extends far beyond classroom walls. Our students are challenged to be global citizens and live meaningful, engaged lives that make a difference.


CEESA Activities & Athletics program operates as an extension of the CEESA schools and organizes a number of sporting, academic and cultural events at the middle and high school levels. The sports and activities facilitate the development of each student through academic, athletic, and artistic/cultural endeavors. At every activity or competition, CEESA Sports and Activities program attempts to maximize the cultural, social and intercultural opportunities available at the host venue.

Sports include but are not limited to:

  • Volleyball
  • Football
  • Basketball
  • Tennis


The Arts thrive at the AISZ. Guided by a talented and creative faculty of trained teachers and artists, our students are taught foundation skills while also being challenged to express their own artistic vision. There are plentiful opportunities to explore the Arts at our campus, where students regularly perform for peers and the community.
