The Tri-State League was an NCAA Division I ice hockey-only conference. The league was the first attempt at creating a conference for hockey programs and, while it did not succeed in its goals, succeeding conferences were able to learn from the mistakes made and flaws in its design to form effective and long-lasting divisions.
