ISI is a member in good standing of the Indiana High School Athletic Association (IHSAA). Our teams compete with other private and public schools from all over Indiana and the Midwest.
We are also an active member of the Indianapolis Independent School League (IISL). Our upper school teams and athletes compete with their peers from 12 other local private schools. In the season culminating IISL tournaments, emphasis is placed on competing to the best of our ability, while still maintaining the characteristics of good sportsmanship.
