Indiana classes are determined by student enrollment, divided into classes of approximately the same size depending on the sport. Zionsville football would also move up to Class 6A after reaching consecutive 5A state championship games. Teams that accumulate six success factor points in tournaments over a two-year period advance in one class. Winning a state championship is four points, a semi-state is three points, a regional is two points and a sectional one point.
If a top team scores two points or more during the two-year cycle, they stay in that class. The Northern District is comprised of 21 of Indiana's counties, which consist of the northern third of Indiana.
