NIT bids by school and conference

This is a list of NIT bids by school (divided by their current conference affiliation). As of the 2014 tournament, 269 schools have made appearances in the tournament. The 12 schools whose names are listed in the last table are no longer in NCAA Division I Men's Basketball, and can no longer be included in the tournament.

Some schools have NIT tournament appearances under previous names. For example, UTEP was known as Texas Western when it won its NCAA title in 1966.
