# Indiana High School Athletic Association

The Indiana High School Athletic Association (IHSAA) is the arbiter of interscholastic competition among public and private high schools in the U.S. state of Indiana.
Member schools are classified into four classes based on enrollment, ranging from the smallest, 1A, to the largest, 4A. Some sports provide specific classification, such as football (six classes) and soccer (three).
The IHSAA's boys and girls basketball tournaments, sometimes dubbed Hoosier Hysteria, are some of the oldest and best-attended state basketball tournaments in the United States.

## Athletic Conferences

In the regular season, most of the member-schools' sports activities are governed by Indiana's high school athletic conferences. Some conferences only offer select sports, while others include all. Some schools maintain independence in certain sports, electing not to compete in a conference.
Some smaller sports are governed by other organizations in Indiana. For example, boys' ice hockey, which has fewer participating teams than other sports statewide, is under the auspices of the Indiana State High School Hockey Association (ISHSHA).

## Controversy

In 2010, the association faced a state lawsuit over the scheduling of girls’ basketball games, which some programs believed disadvantaged girls’ teams by giving more favorable dates and times to boys’ programs. The association won the case when an Indiana judge ruled the schedule was not discriminatory.
