Regular season Michigan High School Athletic Association, or MHSAA, football rankings are compiled by a panel of Associated Press media voters. There are rankings for Divisions 1 through 8, based on pre-determined school enrollment cut-off lines, along with additional rankings for schools fielding eight-player teams.
The top 256 teams in the state of Michigan - based on accumulated playoff points - qualify for the postseason, a format adopted in 1999. Points are awarded based on team record and strength of schedule. Once the field is set, the teams are then placed into eight divisions of 32 teams each based on enrollment. The largest 32 schools compete in the Division 1 playoffs, while the next 32 in size are placed in Division 2, and so forth.
Within each division are four regions of eight teams; each region contains two districts of four teams each. In district and regional play, the home team is determined by playoff points accrued during the regular season. The semi-finals are played at pre-arranged locations and the championship game of each division is played at Ford Field in Downtown Detroit.
Of the smaller schools fielding eight-player teams, the top 16 teams compete in the postseason and are placed into four regions of four teams each. While the first two rounds are played at the site of the team with the highest computer ranking, both the semi-finals and final are played at prearranged sites.
