For football, postseason inclusion was, through 2019, determined by wins and a computer point value, calculated for each team based upon its record and strength of schedule, with the top 256 teams (including all teams with six victories if playing a nine-game schedule) qualifying. These 256 teams were then ordered by enrollment and divided into 8 divisions of 32 teams each. This was nearly unique amongst high school football competition in the U.S. in that many teams do not know which classification they will compete for a state title in until after the regular season has ended; the Illinois High School Association, North Carolina High School Athletic Association, and Wisconsin Interscholastic Athletic Association also have a similar format. The MHSAA announced in 2019 that, beginning with the 2020 season, its football playoff system would change: The aforementioned computer point value (derived from a combination of a team's own record, its opponents' record and its opponents' opponents' record, with points awarded based on which of the four classes each opponent is in) will be the sole method to select playoff teams, and the eight divisions will be set in advance of the season.
