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 through Grade 8. We will be recognized for academic excellence, exceptional and best practice instruction, state of the art facilities, and language and cultural enrichment programs.
