Quick Facts

International School of Arizona is a non-profit 501(c)(3) organization. Donations are tax deductible to the extent allowable by law. Tax ID#86-0900797.

Our mission is to provide academic excellence in Early Childhood School, Lower School, and Middle School through second language immersion. In a diverse, safe and nurturing environment, ISA prepares students to become global citizens.

Our vision is to be a world-class international school for students, from the early age of two, straight through to 8th grade. We will be recognized for academic excellence, exceptional/best practice instruction, state of the art facilities, and language and cultural enrichment programs.

If you're concerned about the effects of a full-immersion program on English scores, where students spend 80-85% of the week in the target language, here are our results on the Stanford 10 Achievement Tests which were conducted with students across the U.S.A. in April 2014:
