The 2010 Illinois High School Association (IHSA) State Championship Tournaments ended the twenty-fifth State Championship Series conducted in Scholastic Bowl by the IHSA. It was the twentieth season in which there were separate State Championship Tournaments held for small schools (Class A) and large schools (Class AA). For the fifteenth year, both tournaments were held at the Peoria Civic Center. The tournaments were held on Friday, March 18, 2011.
Advancement
Teams were assigned to one of eight sectionals within each class. Coaches then seeded the top 8 teams in their sectional. The IHSA then assigned the seeded teams to one of four regionals (1 with 8, 2 with 7, etc), with the remainder of the teams assigned to a regional geographically. The winners of the regionals would advance to their respective sectional tournaments, where they would play a three match round robin to determine a winner. The determination of the geographic boundaries of the Sectional was arbitrarily decided by the IHSA Office.
Tournament Format
Each round was comprised of 30 toss-ups and accompanying bonus questions.
In the State Championship Tournament, teams would be randomly assigned to pools of four, and play a three match round robin. The winners of each pool would advance to the Championship Match, and the runners-up in each pool would advance to play for third place. Ties were broken by head-to-head results or total points scored among tied teams (in the event of a three-way tie).
The top four teams earned trophies and medals for team members, coaches, principals, and activities directors.
