The National Collegiate Athletic Association (NCAA) is divided into three divisions, based roughly on school size. Each division is made up of several conferences for regional league play. Unless otherwise noted, changes in conference affiliation will occur on July 1 of the given year.
This list includes conferences in sports that the NCAA does not fully split into divisions, such as men's volleyball and rifle. Note also that sports in which the NCAA sponsors separate championships for men and women are officially treated by the NCAA as two separate sports.
These conferences sponsor sports which do not have D-II championships.
