Here’s information on how teams make the 68-team field each season.
How are the teams selected for the bracket?
There are two ways that a team can earn a bid to the NCAA tournament. The 32 Division I conferences (31 in 2021) all receive an automatic bid, which they each award to the team that wins the postseason conference tournament. Regardless of how a team performed during the regular season, if they are eligible for postseason play and win their conference tournament, they receive a bid to the NCAA tournament. These teams are known as automatic qualifiers.
The second avenue for an invitation is an at-large bid. The selection committee (more on them in a second) convenes on Selection Sunday, after all regular season and conference tournament games are played, and decides which 36 teams (37 in 2021) that are not automatic qualifiers have the pedigree to earn an invitation to the tournament.
Here is the NCAA’s comprehensive guide to how teams are selected for the tournament.
What is the March Madness selection committee?
The 10-member NCAA Men’s Division I Basketball Committee is responsible for selecting, seeding and bracketing the field for the NCAA Tournament. School and conference administrators are nominated by their conference, serve five-year terms and represent a cross-section of the Division I membership.
How do they decide which teams get an at-large bid?
There are a multitude of stats and rankings that the Selection Committee takes into account, but there is no set formula that determines whether a team receives an at-large bid or not.
What happens once the teams are selected?
Once the field of 68 is finalized, each team is assigned a seed and placed in one of four regions, which determines their first-round matchups and their path to the championship.
What are seeds?
The NCAA men’s basketball tournament is made up of 68 teams. On Selection Sunday, before any tournament game is played, those teams are ranked 1 through 68 by the Selection Committee, with the best team in college basketball — based on regular season and conference tournament performance — sitting at No. 1. Four of those teams are eliminated in the opening round of the tournament (known as the First Four), leaving us with a field of 64 for the first round.
Those 64 teams are split into four regions of 16 teams each, with each team being ranked 1 through 16. That ranking is the team’s seed.
In order to reward better teams, first-round matchups are determined by pitting the top team in the region against the bottom team (No. 1 vs. No. 16). Then the next highest vs. the next lowest (No. 2 vs. No. 15), and so on. In theory, this means that the 1 seeds have the easiest opening matchup in the bracket.
