High school hockey in Missouri consists of two leagues centered in the two largest cities in the state, St. Louis, Missouri and Kansas City, Missouri. The majority of the schools are located in the St. Louis metro area, those teams are members of the Mid-States Club Hockey Association (MSCHA), the larger of the two leagues in Missouri. Schools in the northwest, southwest, central and western portions of Missouri are members of the Mid America High School Hockey League (MAHSHL). High school ice hockey in Missouri is not sanctioned by the Missouri State High School Activities Association (MSHSAA) but is sanctioned by USA Hockey.
The Mid-States Club Hockey Association (MSCHA) is the main high school hockey league in Missouri (and is often referred to as Mid-States). The league is made up of teams in the St. Louis, Missouri metro area, all teams are located in Missouri except for one team, Edwardsville High School, located in Illinois. The MSCHA is a non-profit organization dedicated to the development of high school hockey.
Originally known as the Area High School Club Hockey League, the MSCHA was founded in 1971 with significant seed money and sponsorship from Union Electric, as well as support from the St. Louis Blues, including the donation of the Challenge Cup for the league's winner, and free usage of The Arena for the final. At the time, organized youth hockey was experiencing a boom in the St. Louis area, mostly caused by the Blues' arrival and subsequent appearance in three Stanley Cup finals. Eight teams contested that first season, with DeSmet winning the first championship. Of the eight teams that played that first year, only three can claim to have been in every Mid-States season: SLUH, CBC, and DeSmet. The league grew quickly, achieving a high of over 50 teams in its second year (when it also changed its name to the current MSCHA), but it also experienced a high rate of attrition, as clubs were disbanded due to loss of players or the removal of school support. Nevertheless, throughout the '70s the league enjoyed great success. Plans were tabled for expansion to Kansas City and Columbia, but they were dropped following a dispute over travel costs and the loss of Columbia's ice rinks.
