In Indiana, the classification of high school football teams is based on student enrollment, with teams divided into classes of roughly equal size. For example, Zionsville football moved up to Class 6A after reaching consecutive 5A state championship games.
The Northern District is made up of 21 counties in the northern third of Indiana. Teams that accumulate six success factor points in tournaments over a two-year period advance in one class. Winning a state championship is worth 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 remain in that class.
