This is a list of NCAA Division I Basketball Alignment History. Teams in italics are no longer in Division I. Seasons are listed by the calendar year in which they end--for example, if a school's first Division I season was the 1991-92 school year, it will be listed as having begun in 1992.
Dates used reflect when the school first became eligible for NCAA-sponsored postseason play--either the NCAA tournament for men or women, or the NIT since it was acquired by the NCAA in 2005. Note that it is possible for a school that is not eligible for NCAA postseason play to play in a tournament not operated by that organization. For example, South Dakota State's women's team, which was not eligible to compete in the NCAA tournament until 2009, played in the WNIT, which is not an NCAA-controlled tournament, in 2007 and 2008. Similarly, the Omaha men's team played in the 2014 CIT before becoming eligible for NCAA postseason play in 2016.
