The league features seven of the top ACHA programs from across the country regardless of geographic considerations, with its membership ranging from Lynchburg, Virginia in the southeast to Minot, North Dakota in the northwest.

WMCH began play during the 2019–20 season with teams that had won four of the last seven national championships (Minnesota in 2013, Liberty in 2015, 2018, and 2019), and each of its members had participated in their respective national tournaments within the past two seasons (Minot State did so in Division 2, the rest in Division 1).

The conference lived up to that billing by earning four of the eight available bids to the 2020 ACHA National Tournament, before it was canceled due to the COVID-19 pandemic.

† The WMCH did not formally declare a regular season champion.

Liberty was the top-seeded team for the league playoffs due to having the highest ACHA ranking of the members.
