Decoding the NCAA Hockey Tournament Selection Process

The annual NCAA Division I Men's Ice Hockey Tournament, a high-stakes single-elimination competition, has been a cornerstone of college hockey since 1948. Orchestrated by the National Collegiate Athletic Association (NCAA), this tournament crowns the top men's team in Division I, showcasing the pinnacle of collegiate hockey talent in the United States. This article seeks to explain the intricacies of the selection and seeding process, clarifying how teams earn their coveted spots and how the tournament bracket takes shape.

Tournament Overview

The NCAA Men's Division I Ice Hockey Championship is a single elimination competition that has determined the collegiate national champion since the inaugural 1948 NCAA Men's Division I Ice Hockey Tournament. The tournament features 16 teams representing all six Division I conferences in the nation. The Championship Committee seeds the entire field from 1 to 16 within four regionals of 4 teams.

Automatic Qualification: Conference Champions

Six teams receive automatic bids by winning their conference tournaments, securing their place in the national competition. The six conferences that receive automatic bids are:

Hockey East
ECAC Hockey
Big Ten
NCHC
CCHA
Atlantic Hockey (AHA)

The NCAA mandates that a conference receives an automatic bid to the NCAA Tournament if it exists for at least two years and has at least six teams. There is no mandate on how a conference should award the automatic bids, though almost every conference in every sport awards it to the winner of that conference's postseason tournament.

At-Large Bids: Selecting the Remaining Teams

With the automatic bids accounted for, the remaining 10 teams are selected on an at-large basis by the Division I Men’s Ice Hockey Committee. This selection process relies on a number of criteria to evaluate team performance and potential.

Key Evaluation Criteria

In the comparisons between teams, the team with the most points will be selected. Several factors are considered when the committee makes their selections:

RPI (Rating Percentage Index): The RPI was created by the NCAA in the late 1970s, originally to help the basketball selection committee. It's a method of adjusting for the varying strengths of schedule of the different teams. Originally, the RPI was weighted 25-50-25, as it is in men's basketball. At one time, hockey experimented with making a team's own winning percentage comprise 35% of the RPI, which worked OK when there were just four conferences that were generally comparable. But it wound up tilting the RPI too much in favor of strong teams from weak conferences -- particularly with the advent of "mid-major" conferences such as Atlantic Hockey (1999) and College Hockey America (2001) -- so the composition of the RPI was returned to 25-50-25. For purposes of calculating a final RPI, games are weighted based upon whether they are home or road games. Road wins and home losses are weighted by a factor of 1.2, while home wins and road losses are weighted by 0.8. Unlike basketball, all components of the RPI are weighted. As of 2021-22, when college hockey went to 3-on-3 overtimes across the board, The Committee decided to weight these differently. The manual notes, "If the points awarded in the RPI for a win in a postseason conference tournament game are fewer than the average regular-season RPI point value per game, then points awarded for the postseason tournament game will be deleted. This is being done so that an institution is not penalized for a win in a postseason conference tournament by having its overall RPI decrease.
Head-to-Head Competition: Head-to-head competition, results versus common opponents, the quality wins bonus (QWB) and home/away weighting are also factored in. Each of the above criteria carries one point, aside from head-to-head competition, "which will carry the number of points equal to the net difference in the results of these games (e.g., if Team A defeats Team B three out of four games, Team A would receive two points in the selection process)."
Results Versus Common Opponents: As of 2012-13, two teams' records vs. common opponents is not a straight win-loss percentage. Instead, you get a win-loss percentage against each individual common opponent, then average all those percentages together. This helps smooth out situations, for instance, where a team can beat up on the same opponent four times, while the other team in the comparison only was 1-0 against that opponent. 4-0 vs. 1-0 was a big difference. Note: The various RPI tweaks have no bearing on Record vs. CO and Head-to-Head criteria. In other words, home/road weighting and OT weighting, etc…, are not factored into the Record vs. CO and H2H.
Quality Wins Bonus (QWB): A "Quality Win Bonus" was added for the 2013-14 season. For any win against the top 20 of the RPI, a team is awarded "bonus points" on a sliding scale from 1-20. In other words, a team is given a .050 RPI bonus for defeating the No. 1 team, sliding down to .0025 bonus for defeating the 20th team. The total bonus for the season is divided by the amount of games played (weighted for home-road), to give a final bonus figure. There was previously a more vague bonus system, which applied to wins against non-league teams in the Top 15 of RPI.
Home/Away Weighting: For purposes of calculating a final RPI, games are weighted based upon whether they are home or road games. Road wins and home losses are weighted by a factor of 1.2, while home wins and road losses are weighted by 0.8.

Seeding the Tournament: Setting the Stage for Competition

The Championship Committee seeds the entire field from 1 to 16 within four regionals of 4 teams. The top four teams in the field are awarded the No. 1 seeds, the next four the No. 2 seeds, the next four the No. 3 seeds and the final four the No. Programs that are hosting regionals and qualify for the tournament will be placed at home. The committee tries to steer away from matchups between teams from the same conference while also maintaining bracket integrity.

Seeding Methodology

Since the advent of the objective system of Comparisons, there has always been a step-by-step methodology to determining the seeds. But since going to a 16-team tournament, the methodology has become highly straightforward. For one, there was a time when the emphasis was more upon individual comparisons. Now, the Pairwise Comparison chart, as described above, is used to rank the teams in a straight 1-16.

The teams are then grouped into four "bands" of four, with teams 1-4 given No. 1 seeds (Band 1), 5-8 given No. 2 seeds (Band 2), 9-12 given No. 3 seeds (Band 3), and 13-16 given No. 4 seeds (Band 4).

Regional Placement and Bracket Integrity

In setting up the tournament, the Championship Committee seeks to ensure "competitive equity, financial success and likelihood of playoff-type atmosphere at each regional site." A team serving as the host of a regional is placed within that regional. The top four teams are assigned overall seeds and placed within the bracket such that the national semifinals will feature the No. 1 seed versus the No. 4 seed and the No. 2 seed versus the No. 3 seed should the top four teams win their respective regional finals. Number 1 seeds are also placed as close to their home site as possible, with the No. 1 seed receiving first preference. The committee tries to steer away from matchups between teams from the same conference while also maintaining bracket integrity.

For the remaining teams, the current practice no longer favors geography, but instead places a strong premium upon maintaining a "serpentine" order. i.e. 1 vs. 16, 2 vs. 15, 3 vs. 14, etc… with the second-round set up to preserve, if possible, a 1 vs. 8, 2 vs. 7, 3 vs. 6, 4 vs. 5 setup. The committee will mix and match teams within bands in order to preserve the two sacrosanct issues mentioned above, but will not move teams outside their band. Generally speaking, in order to avoid an intra-conference matchup, the committee prefers flip-flopping the No. 3 seeds within their band to different regionals, as opposed to No. 2 seeds.

The regional winners that will face each other in the national semifinals (the Frozen Four semis) are pre-determined prior to the start of the tournament under the assumption that the four No. 1 seeds will advance. The region of the No. 1 overall seed is matched with the region of the No. 4 overall seed, and same for No. 2 and 3. This holds even if the No.

Hosting Considerations

Programs that are hosting regionals and qualify for the tournament will be placed at home.

Tournament Structure: Regionals and the Frozen Four

At each site, four teams will compete in single-elimination Regional Semifinal competition. The two winning teams will then compete against each other in single-elimination Regional Final competition at the same site. The winning team from each of the four Regionals will advance to the Men's Frozen Four.

Historical Context and Evolution

Up until 1976, the NCAA tournament invited two teams from each of the two major regions: East and West. Initially, all teams were invited based upon their regular season performance with the NCAA selection committee occasionally deferring to an in-season or unofficial tournament to make their selection easier. Over time, as each of the two regions became dominated by single conferences, the selection committee would just choose the top two teams from each of the two leagues or, when held, the champion(s) and runners-up of the conference tournaments.

During the first three decades of the national tournament other conferences did exist, however, most of these were either unofficial or contained teams that were largely regarded as inferior (MIAC for example) and were ignored by the selection committee. Things began to change in the 70s when several new programs joined the top level of play. For the first half of the decade, the NCAA tournament continued its recent pattern of only inviting two teams from both ECAC Hockey and the WCHA. However, after several years of petitioning by the new league, the selection committee finally changed the tournament format for the 1976 series. While it could continue to invite two teams from the more established leagues, the committee gave itself the ability to invite up to 4 additional teams to the tournament as it saw fit. Under this policy, the CCHA tournament champion was given a de facto automatic bid but the committee was reticent to include any additional teams in the field.

After failing to use most of the additional slots made available by the rule chance, the NCAA tournament was expanded into three full rounds in 1981. At the time, with just one large conference comprising all eastern teams, the ECAC subdivided itself into three regions. The conference's tournament champion as well as the two division champions from the other groups would receive automatic bids. For the west, the WCHA would continue to name two tournament co-champions who would each receive an automatic bid while the single CCHA champion would also receive an automatic bid. Within two years this cumbersome policy was abandoned and the NCAA tournament would only offer a single automatic bids to each of the three conferences with the rest of the field being made up of at-large bids.

The Advent of Objective Rankings

Beginning in 1981, when at-large bids were first officially introduced, the selection of teams that were offered bids was based upon their national rankings in polls. These were primarily done by some combination of head coaches and sports writers and tended to favor more established programs. In the early 1990s, the selection committee began to try and compare teams objectively by instituting a new ranking system. Some of the initial rankings that resulted were decried as some of the tournament invitees possessed arguably subpar records and their inclusion pushed out teams that were widely regarded as superior, such as Brown in 1993. Since then, at-large bids were offered to teams based upon their PairWise ranking which provided a single number for each program based upon several categories. The categories were altered and changed over time with each receiving different weights or priorities, however, by 2014 the system was largely seen by the committee as sufficient and went unchanged for several years afterwards.

Pairwise Comparison System

What it is: In the early 1990s, the NCAA Men's Ice Hockey Committee instituted a system designed to objectively compare teams to each other. The methodology evolved over time, getting more and more precise until becoming as it is today. Also, the criteria used has fluctuated somewhat over time. Record vs. The most notable change to the selection criteria over the years has been the reduction in the number of criteria, and more heavy reliance on RPI (plus adjustments). There was once a "Record in Last 16 (or 20) Games" component. In addition, as of 2013-14, the Record vs.

How it's applied: Each "Team Under Consideration" (TUC) is compared to every other "Team Under Consideration" (see below for TUC definition), using the three criteria. Within each "comparison," one point is awarded for winning each criterion. One point is also awarded for each head-to-head win. The team with the most "criteria points" at the end of this process, wins that comparison. If the comparison ends in a tie, it's broken by determining which team has the better RPI. This procedure is repeated for every possible TUC pair.

How the teams are ultimately selected: Using the chart, the teams are listed in order on the basis of most "comparisons" won. When taking out the teams that qualify automatically (by virtue of winning their conference tournament), the remaining top teams are then selected to fill out the 16-team field. If there is a tie in the amount of total comparisons won, this tie is also broken by comparing the two teams' RPI. (Note: That method of breaking ties is not outlined anywhere, and has simply been ascertained through experience and observation. Likewise, the ordering of teams in the chart -- based on total comparisons won -- is also not outlined anywhere. Other methods have been used in the past that, while practically amounting to the same thing, are not exactly the same.

History: To understand this further, it's important to know the history of the system. There came a time when the hockey community decided it wanted to take subjectivity out of the process. The Pairwise Comparison system was born. Originally, the system was designed as a way to objectively compare teams that were close in RPI, i.e. "on the bubble" of getting into the tournament. Once that bubble was ascertained by the committee (a subjective process in a sense, but not practically), the committee checked the individual comparisons among the teams, and figured out who was "winning the comparisons" against each other. It was only third-party sources -- after learning of this methodology's details -- that originally totaled up all the "comparison wins" and presented them in a chart in ranking form. College Hockey Online, the first Internet-only college hockey media organization, which went on-line in 1996. Some time over the next seven years, life imitated art -- in other words, the committee's methods morphed, and it began to actually utilize the chart, as is, without doing any micro-observation of the individual comparisons.

Team Under Consideration: As of 2013-14, the Record vs. TUC criterion has been removed, effectively making every team a TUC. Prior to that, a team under consideration was one which had an RPI of .500 or higher.

Committee Composition and Responsibilities

One representative from each of the six conferences make up the men's ice hockey committee (heretofore referred to as "The Committee"). Terms are 4 years long, and end in August of the year listed.

Common Misconceptions

Whether everyone agrees with this process for selecting and seeding the teams or not, the methodology is well-defined and transparent. There is no subjectivity in the selection process, other than the pre-determined subjectivity of which criteria is used. The selections are not based upon polls. They are not based upon the whim or opinion of any committee member. … There are many common misconceptions. For example, that teams which win their respective conference tournament will (or should) get preferential treatment in seeding; or that …
