The 1992 Illinois High School Association (IHSA) State Championship Tournaments was the sixth State Championship Series conducted in Scholastic Bowl by the IHSA. It was the first time that there were separate State Championship Tournaments held for small schools (Class A) and large schools (Class AA).
1992 marked the first time where small schools and large schools would be separated and compete for different State Titles. While the process for determining the cutoff for determining classification has changed over time, it has roughly hovered around the 725-750 student area. Thus, about 30-40% of the schools would compete as Class AA, and 60-70% of the schools would compete as Class A. This permits a roughly equal number of students to compete in each class.
In each class, the state was divided into 16 areas, termed in Illinois as Sectionals. Each sectional hosted a tournament, the winner of which advanced to the State Championship Tournament. The determination of these geographic boundaries was arbitrarily decided by the IHSA Office.
Each round was comprised of 30 toss-ups and accompanying bonus questions. The sectional tournaments and State Championship Tournament were all single elimination. Teams were randomly assigned to positions in the bracket without regard for record or performance.
The exception to the single elimination format occurred in the semifinals, where the two semifinal losers played a third place match. The top four teams earned trophies and medals for team members, coaches, principals, and activities directors. The trophies were of the design smaller than that of the athletic trophies given out by the IHSA.
The Class A State Championship Tournament was held at Rochester Elementary School.
The Class AA State Championship Tournament was held at Lanphier High School in Springfield. This was the second year that Lanphier at hosted a State Championship Tournament, and is the only site to host a State Championship Tournament in both the "Open" Era and the "Two-Class" Era.
1992 saw two Class AA schools not appear for the State Championship Tournament. One of these schools is known to be Maine South. The two schools had their Sectional titles stripped by the IHSA. Thus Hinsdale Central and Centralia earned byes in the Octafinals. As they happened to be next to each other in the pre-arranged bracket, they played each other in the Quarterfinals.

- This was the first time that the Class A and Class AA tournaments would be played at separate sites. This practice would continue through the 1996 season.
- This was the first time the two losers of the semifinal matches competed for third place.
