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.
Indiana's classes are determined by student enrollment, broken into classes of roughly equal size depending on sport. The 2011-12 school year marks a change in the classification period, as schools are reclassified in all class sports biennially instead of quadrennially.
It is also important to note that some schools (mostly private) are placed in classes higher than their enrollment. This is due to a new IHSAA rule that took effect for the 2012-13 year that dictates that school that wins two state championships in a row is automatically moved up into the next class.
