The NCAA men's volleyball tournament, officially titled the NCAA National Collegiate Men's Volleyball Championship, is an annual competition that determines the National Collegiate Athletic Association (NCAA) championship in American college men's volleyball. It had been the only NCAA championship in the sport from 1970 until 2012, when the NCAA launched a Division III championship. Unlike most NCAA sports, men's volleyball uses a modified version of the National Collegiate championship format, which means Division I and Division II teams compete against each other in the same tournament. In the past, schools from the Pacific Coast region have dominated this sport, in particular UCLA with coach Al Scates leading the program to 19 NCAA titles (more than any other coach). Competition structure Before the 2011–12 school year (2012 championship), men's volleyball did not have an official divisional structure; even now, that structure is truncated. The National Collegiate Championship remains as the NCAA's top-level championship, but Division III members now have their own championship event. With the introduction of an official Division III championship, schools in that division are no longer eligible for the National Collegiate Championship. The last exception was Rutgers–Newark, whose men's volleyball program had been a grandfathered scholarship program, and could compete for the National Collegiate Championship through 2014. Rutgers–Newark completed a transition to Division III men's volleyball at the end of that season, and joined the D-III Continental Volleyball Conference effective with the 2015 season. There are three general regions for men's volleyball: "West", "Midwest", and "East". As of the current 2023 NCAA men's volleyball season, five "major conferences", defined here as leagues that include full members of Division I, represent these regions. The three "traditional" major conferences are the Mountain Pacific Sports Federation (MPSF), Midwestern Intercollegiate Volleyball Association (MIVA), and Eastern Intercollegiate Volleyball Association (EIVA). In the 2018 season, the ranks of "major" conferences expanded to include the Big West Conference, the first Division I all-sports conference ever to sponsor men's volleyball. The Northeast Conference (NEC) became the second D-I all-sports conference to sponsor men's volleyball in the 2023 season. As of that season, two Division II conferences sponsor men's volleyball at the National Collegiate level. Conference Carolinas (CC) was the first NCAA conference ever to sponsor men's volleyball as a scholarship sport, having launched its men's volleyball league in the 2012 season. The 2021 season was to have been the first for the Southern Intercollegiate Athletic Conference
