As of the most recently completed 2024âÂÂ25 basketball season, 362 men's college basketball programs competed in the National Collegiate Athletic Association's Division I. This number includes programs transitioning from a lower NCAA division, most from Division II and one from Division III. For the 2024âÂÂ25 season, four schools became full Division I members, having completed transitions from Division II, while two schools started transitions from Division II.
Each program employs a head coach. As of the 2025âÂÂ26 season, the longest-tenured head coach is Greg Kampe, who has been head coach at Oakland since 1984. However, Kampe does not have the longest tenure at the Division I level because Oakland played in NCAA Division II before the 1997âÂÂ98 season. The longest tenure at the D-I level is that of Tom Izzo of Michigan State, who has coached the Spartans since 1995âÂÂ96.
