The ACHA was established on April 20, 1991. Fifteen charter members met during the Chicago Showcase in
Skokie, Illinois at the North Shore Hilton. These member teams had been playing college hockey for many years but wished to legitimize its play by standardizing some of its procedures. The members that created the organization were Tom Keegan (ACHA), Al Murdoch (Iowa State), Joe Battista (Penn State), Jim Gilmore (Ohio), Ernie Ferrari (Stanford), Howard Jenks (California), Jeff Aikens (North Dakota State), Don Spencer (West Virginia), Jim Barry (Navy), Scott Fuller (Navy), Leo Golembiewski (Arizona), Ron Starr (DePaul), Cary Adams (PCHA), Jim Warden (PCHA) and Jack White (UCLA). The inaugural year of the ACHA was the 1991–1992 season. The goal of the organization was to create an impartial governing body to monitor national tournaments, player eligibility, and general oversight. Over the years the ACHA quickly grew to over 150 teams in three men's divisions. and

In 2017, the ACHA adopted a new hosting format for holding the annual National Championship Tournament for all Men's & Women's Divisions.
