The MHSAA is a private, not-for-profit corporation of voluntary membership by over 1,300 public and private senior high schools and junior high/middle schools which exists to develop common rules for athletic eligibility and competition. No government funds or tax dollars support the MHSAA, which was the first such association nationally to not accept membership dues or tournament entry fees from schools. Member schools which enforce these rules are permitted to participate in MHSAA tournaments, which attract approximately 1.6 million spectators each year.

Due to changing enrollment 20 schools moved either up or down a class.
