The NCAA Division I Men’s and Women’s Basketball Championships
The men’s and women’s tournaments feature a 68-team bracket, composed of 31 automatic qualifiers and 37 at-large teams.
31 automatic qualifiers — Teams that win their conference tournaments receive automatic bids.
37 at-large teams — The NCAA Division I Men’s and Women’s Basketball Committees use a combination of metrics and evaluation tools to choose the at-large teams.
Each tournament features an opening-round First Four, followed by first and second rounds, regional semifinals and finals — affectionately known as the Sweet 16 and Elite Eight, respectively — and the Men’s and Women’s Final Fours.
Men’s and women’s teams that do not make the field of 68 are eligible for the National Invitation Tournament and the Women’s Basketball Invitation Tournament. The NIT and WBIT are both managed by the NCAA and have their own selection process.
Who selects the teams?
The NCAA Division I Men’s and Women’s Basketball Committees, respectively, oversee the selection, seeding and bracketing process for each tournament. These committees evaluate teams starting with the first night of the season and all the way until Selection Sunday using data-driven metrics, game results and expert observations to determine the best at-large teams and ensure competitive balance in the tournaments. The committees meet multiple times throughout the season to analyze team performance and adjust rankings accordingly. That’s nearly five months of evaluating!
The Division I men’s and women’s committees are composed of conference commissioners, athletics directors and experienced administrators from across Division I basketball. Each committee consists of 12 members serving five-year terms, ensuring a fair and balanced approach to selection.
Selection begins with each committee member submitting an initial ballot on the first day of the selections meeting, followed by rounds of voting and discussion until the final bracket is set.
What metrics are used to evaluate teams throughout the season?
Committee members rely on a broad set of observation, consultation and data resources throughout the season and during selection week to make informed decisions.
These resources include game evaluations, conference monitoring, coaches rankings, box scores, head-to-head results, common-opponent results, imbalanced conference schedules and results, nonconference strength of schedule, quality wins and losses, road performance, player/coach availability and computer metrics.
Two commonly referred-to computer metrics used in the men’s and women’s process are the NCAA Evaluation Tool (or NET) and Wins Above Bubble (WAB).
How are the brackets built?
The Division I Men’s and Women’s Basketball Committees are responsible for selecting the 37 at-large teams and ranking them into their respective brackets. While there are some differences in the details of how each bracket is created, the general process and principles of selecting the teams and seeding them are similar.
