The American Collegiate Hockey Association (ACHA) is a college ice hockey association. The ACHA's purpose is to be an organization of collegiate affiliated programs, which provides structure, regulates operations, and promotes quality in collegiate ice hockey. The ACHA currently has three men's and two women's divisions and includes approximately 450 teams from across the United States and Canada. Most ACHA teams offer few athletic scholarships and typically receive far less university funding. The ACHA offers an opportunity for college hockey programs that struggle with large budgets and Title IX issues, as an alternative to the National Collegiate Athletic Association (NCAA) financial structure.

The Tri-State Collegiate Hockey League (TSCHL) is an ACHA Division II level ice hockey league. ACHA Division II level consists of players with previous Jr. A, AAA or Midget Major experience, along with high caliber high school experience. The level can range from varsity high school up to NCAA Division III skills, depending on the programs.
