Member schools

The conference has had two significant membership changes in the 2020s. First, the MAC announced in April 2019 that York College of Pennsylvania would join from the Capital Athletic Conference in 2020.^[2] The following month, the MAC announced that upon York's arrival, the MAC Commonwealth and MAC Freedom would be realigned so that each would have 9 members. Eastern moved from the MAC Freedom to the MAC Commonwealth, while Arcadia and Lycoming moved in the opposite direction.^[3] Then in 2023, Lycoming and Wilkes left both the MAC Freedom and the overall MAC, leading the MAC to move Lebanon Valley from MAC Commonwealth to MAC Freedom in order to balance the membership numbers.

Footnotes

1. While officially sponsoring ice hockey, the larger MAC does not conduct a conference tournament; all MAC ice hockey schools compete in the single-sport United Collegiate Hockey Conference for that league's automatic bids to the NCAA Division III men's and women's tournaments. The MAC uses regular-season results of UCHC games involving MAC members to extrapolate a conference champion. The relationship between the MAC and UCHC is similar to that in Division I between the Ivy League and ECAC Hockey.
