The NCAA Evaluation Tool (NET) rankings are updated daily from early December through Selection Sunday. The rankings are based on two main factors: the Team Value Index (TVI), which rewards teams for beating quality opponents, especially away from home; and an adjusted net efficiency rating, which accounts for the strength of the opponent and the location of the game. While the exact time of the update is not specified, one source mentions that it is usually updated by 8:30 EST.

The NCAA Evaluation Tool (NET) rankings are updated daily
The NET rankings algorithm is composed of two parts: the Team Value Index (TVI) and an adjusted net efficiency rating. The TVI rewards teams for defeating quality opponents, especially when playing away from home. The adjusted net efficiency rating accounts for the strength of the opponent and the location of the game (home, away, or neutral).
The NCAA Evaluation Tool has undergone changes to increase its accuracy and simplicity. Initially, it comprised five components, which were reduced to just two. The updated NET rankings now reflect a more accurate measure of the strength of a team's schedule, considering factors such as opponent strength and game location to determine an expected win percentage.
While the NET rankings are updated daily, the timing can vary. Updates are typically released between 8:00 and 8:30 a.m. EST, but there may be days when the rankings are updated earlier or later.

NET rankings are based on two factors: Team Value Index (TVI) and adjusted net efficiency rating
The NCAA Evaluation Tool (NET) ranking system is used to rank college basketball teams. The NET rankings are based on two factors: Team Value Index (TVI) and adjusted net efficiency rating.
The Team Value Index (TVI) is a results-based feature that rewards teams for beating quality opponents, particularly away from home. The TVI only considers games against Division I opponents and is based on results. The algorithm factors in the opponent, location, and winner to produce a TVI score. The strength of schedule is considered in the TVI, but its exact impact is not publicly known.
The adjusted net efficiency rating is a team's net efficiency, adjusted for the strength of opponents and location (home, away, or neutral) across all games played. A team's net efficiency is calculated as the offensive efficiency (points per possession) minus the defensive efficiency (opponent points per possession). A higher net efficiency against stronger opposition is valued more highly than the same efficiency against lesser opponents, and achieving a certain efficiency on the road is rated higher than the same efficiency at home.
The NET ranking system was introduced in 2018 to replace the Rating Percentage Index (RPI) system. In May 2020, the NCAA announced changes to the NET to increase accuracy and simplify the metric by reducing the number of components from five to two. The NET rankings do not include game date or game order, so a team's first game counts the same as its 30th. The NET rankings are updated daily and play an important role in establishing a team's resume.

The strength of schedule is a key consideration in ranking teams
The strength of a team's schedule is a key consideration when ranking teams in any sport. This is especially true if teams in a league do not play each other the same number of times. In the context of sports betting, strength of schedule (SOS) is a vital component in the overall scheme of things. Simply looking at a team's record is not enough to understand how good they are.
In the National Football League (NFL), the strength of schedule is the combined record of all teams in a schedule, and the strength of victory (SOV) is the combined record of all teams that were beaten in that schedule. For example, opponents of the 2016 New England Patriots had a combined record of 111-142-3 (a win percentage of 0.439, the SOS), and the Patriots' wins came against teams with a combined record of 93–129–2 (a win percentage of 0.420, the SOV). The NFL uses strength of schedule as a secondary tie-breaker for divisional rankings and playoff qualification, and as a primary tie-breaker for the NFL Draft.
In the National Basketball Association (NBA), the 30 teams are all guaranteed to face each other at least twice in an 82-game regular season, although intra-division games are more frequent (as many as four times). The NBA does not use strength of schedule as a tie-breaker, but it is still an important factor in evaluating the quality of a team.
In college basketball, the NCAA Evaluation Tool (NET) rankings are the primary sorting tool for evaluating teams. The NET rankings include the Team Value Index (TVI), which rewards teams for beating quality opponents, particularly away from home. The adjusted net efficiency rating takes into account the strength of the opponent and location (home/away/neutral) across all games played. The overall and non-conference strength of schedule has been modernised to reflect a truer measure of how hard it is to defeat opponents.
In summary, the strength of schedule is a key consideration in ranking teams because it provides context for a team's performance. By taking into account the quality of a team's opponents, the strength of schedule allows for a more accurate evaluation of a team's capabilities.

NET rankings are one of the biggest factors in determining the NCAA Tournament field
The NCAA Evaluation Tool (NET) rankings are a crucial factor in determining the NCAA Tournament field. Introduced in 2018, the NET rankings serve as the primary evaluation tool for college basketball teams, offering a more accurate and comprehensive assessment of team performance. The NET rankings consider various factors, including wins, losses, strength of schedule, and efficiency, to provide a detailed picture of a team's strength and worthiness for the tournament.
The NET rankings are designed to address some of the limitations of the previous RPI system, which primarily relied on winning percentages and opponent strength. By contrast, the NET rankings take into account a broader range of factors and use machine learning techniques to optimize the ranking model. This allows for a more dynamic and nuanced evaluation of teams, ensuring that the rankings are as accurate as possible.
One of the key advantages of the NET rankings is their ability to consider the strength of schedule. This factor takes into account the difficulty of each game on a team's schedule, assigning a difficulty score based on opponent strength and game location. By aggregating these scores, the NET rankings can provide a more accurate prediction of a team's expected win percentage, which is crucial in determining their overall strength and tournament readiness.
The NET rankings also utilize the quadrant system, which organizes the quality of wins and losses based on game location and opponent ranking. Quadrant 1 wins and Quadrant 3/4 losses play a significant role in the NCAA tournament selection and seeding process. This system ensures that teams are evaluated based on the level of competition they have faced, providing a more informed assessment of their performance.
Overall, the NET rankings are a critical tool in determining the NCAA Tournament field. By considering a range of factors and utilizing advanced analytical techniques, the NET provides a more accurate and reliable evaluation of college basketball teams. The rankings play a pivotal role in establishing a team's resume and their potential success in the tournament.
