The American Collegiate Hockey Association (ACHA) began as a men's collegiate hockey league in 1991, and quickly grew to a league of over 150 teams in three men's divisions. The Women's Division 2 was added in 2006, and the ACHA currently boasts five divisions with over 350 teams from across the nation. The purpose of the ACHA is to support quality, unity and regulation of four-year intercollegiate hockey programs nationwide. In order to do this, the ACHA has developed organization By-Laws and a Policies and Procedures Manual to provide the policy foundation for the organization as it works to fulfill its purpose. These documents are reviewed yearly at the ACHA's annual meeting. The American Collegiate Hockey Association is a chartered non-profit corporation. It is classified as a 501(c)(3) organization with the Internal Revenue Service.
