This school is a the best environment I could have my children in in Indianapolis. The teachers, staff and administrators are incredible-they are constantly innovating new ways to develop curriculum that has meaningful, long-term impacts for our children's futures--and all done in a language immersion environment! After 5 years and with 3 children here, I highly recommend ISI to anyone who values culture, language, diversity, systems thinking and compassion. The new Head of School is a dynamic leader who will continue to bring about positive change as well.
