You won’t find another school like ours in Indiana or even the Midwest. The combination of International Baccalaureate® (IB) programs, immersion and dual language learning in French, Mandarin, Spanish, and English, and enhanced cultural experiences make our academics distinct.
It is the smaller classes, personalized attention, and differentiated instruction that makes our approach to education so successful in preparing students to be inquiring, knowledgeable, confident, and caring young people ready for college and beyond.

athletics

At the International School of Indiana (ISI), we strive for balance in the lives of our students. We believe that body, mind, and spirit work best when they’re working together.

So, we offer over 20 athletic teams annually for students in grades 5 to 12, and joining a team is as simple as attending the first scheduled practice. Through our open participation policy, ISI provides athletic opportunities to all our students. Every student is encouraged to take part in athletics as a participant, team manager, or supporter.

clubs & ActivitIes

ISI offers more than 40 clubs and extracurricular activities for students each year.
 
Opportunities that go beyond the classroom give each student an ISI experience that is uniquely theirs. With a student population as diverse, self-motivated, and engaged as ours, it is not surprising that there’s so much to do. Students can participate in any combination of student activities, including fine arts, travel and field trips, and special-interest clubs. Many groups have been founded on the initiative of the students themselves.
