Illinois High School Association

The Illinois High School Association (IHSA) governs interscholastic athletics and activities for its Illinois member schools. In girls volleyball, it administers the state series across four classes, publishing participation materials, sites, assignments, seeds, schedules, scores, brackets, state-final information, results and historical records. IHSA also maintains a member-school index and sport resources. Its purpose is to supervise and promote educationally based interscholastic competition; it is a statewide secondary-school athletic association, not a club-volleyball federation.
