Two all-sports conferences, the Division I Ivy League and Division III Middle Atlantic Conference, officially sponsor ice hockey for both men and women, but neither hold conference tournaments nor compete for their own automatic bids to the NCAA tournament. All of the hockey-sponsoring schools in both leagues are members of hockey-only leagues and compete for those leagues' automatic bids, with Ivy League members competing in ECAC Hockey and MAC members competing in the United Collegiate Hockey Conference. The Ivies and MAC both extrapolate their own conference champions from results of regular-season games between their own members.
The Northeast-10 sponsors a championship for its members that play men's ice hockey, but the NCAA doesn't currently sponsor a national championship at Division II level for either sex. All members of that conference with women's teams participate in the NEWHA.
