Welcome to the International School of Indiana

The International School of Indiana (ISI) offers the Midwest's most distinct academics for students age 3 to grade 12. 

ISI is a rare school community thanks to an unmatched richness of diversity. Our 600 students and 115 faculty and staff members represent more than 50 different nationalities. But the values of the U.S. Midwest are also at the heart of the institution with more than 60% of our families Central Indiana natives, and there are no previous language studies required for ISI enrollment.

ISI offers all enrolled students access to certified full-continuum International Baccalaureate (IB) programming and full language immersion for age three through grade 5 students. ISI also plays a vital role in Indiana’s increasingly global business community by supporting the recruitment of top international professional talent. Through these programs, the International School of Indiana (ISI) promotes a dynamic framework in which to understand other cultures and perspectives, and it is fundamental to our mission at ISI to ensure students are ready for the world stage.

We hope you’ll take a much closer look and learn about ISI and how we are different. Schedule a tour or attend an open house. We think you’ll see what generations of students and parents already know: the International School of Indiana is the premier school in the Midwest when it comes to preparing students for the world we haven’t yet imagined. It’s the world our next class of students will graduate into—the one they will help to build.
