| Independents |
The schools listed below are members of the Indiana High School Athletic Association and are not members of a conference. Of these, several were at one time members of a conference but became independent because of budget and travel concerns. However, some of them, mostly private schools, are also independent in order to better prepare for the state tournament, a practice that the IHSAA has begun to crack down on in recent years.
