RPI, Rating Percentage Index is a statistical system used to comparatively rank teams. RPI is transparent as anyone can calculate the number by looking at standings.

The purpose of the RPI is to seed teams into state brackets using this statistical system.

The formula set to be used is: RPI = (40% x MWP) + (40% x OWP) + (20% x OOWP)


  • MWP (Modified Winning Percentage): Divide the number of possible points by the number of total available points from games played accounting for the adjustment between classifications.
  • OWP (Opponents Winning Percentage): Average of the winning percentage of a team’s opponents (Note: this is not calculated via the combined record of the opponents, but rather by averaging the winning percentage of the opponents).
  • OOWP (Opponents’ Opponents Winning Percentage: Same process as OWP except the calculation is with the opponents of the team’s opponent. **Note: there is an exception for out-of-state opponents – see below.
  • Any Utah teams that play out-of-state teams will be expected to monitor those teams' schedules and scores on a weekly basis throughout the season to make sure scores are entered to MaxPreps. Coaches and athletic directors will be responsible for contacting the out-of-state schools if scores are not being entered. Currently, each of the states surrounding Utah (Arizona, Colorado, Idaho, Nevada, New Mexico & Wyoming) already require their schools to input scores into MaxPreps.

    When calculating out-of-state opponents, states directly bordering Utah (AZ, CO, ID, NM, NV, WY) will count the same as UHSAA schools for both direct winning percentage and their opponents’ winning percentage. For non-bordering states, their direct winning percentage will count in full (such as .750) and each of their opponents will have a .500 winning percentage assigned. Were this not the case, schools would be chasing thousands of opponents of out-of-state opponents over the course of a season. The .500 figure was selected because it is the average value of opponents' opponents winning percentages across all sports in the data that's been run.

    Out of country opponents will not be counted.

    The RPI system will be an accurate reflection of all regular and region/postseason games. Teams could be seeded into the state bracket based on their RPI ranking versus the previous region rotation which could result in the top teams in the same side of the bracket. Classifications with unbalanced regions will also have better representation in the state tournament.

    Yes, all games played through the region qualifying tournaments will be included.

    Score reporting is essential for an accurate RPI. Scores will be entered by coaches into the Teams by MaxPreps app or on MaxPreps.com. The UHSAA will publish the RPI on its website at uhsaa.org. Any other publication sites may not be accurate.

    No, only scores from regular season and region games vs varsity teams should be reported. When entering a game vs a non-varsity opponent, it is important a school selects ‘Non-Varsity Opponent’ as the opposing team in MaxPreps. Otherwise, the result will appear on the opponents’ varsity schedule and factor into the RPI. If a school does put any of these games on their schedule, they should be marked as ‘Exhibition’ in MaxPreps.

    The RPI will only be published on UHSAA.org. Rankings seen anywhere else may not be accurate. The RPI will not appear on MaxPreps.com. The rankings seen on MaxPreps are separate and have no impact on the RPI.

    Baseball, basketball, football, lacrosse, soccer, softball and volleyball

    A 15 percent adjustment will be used between classifications.

    Out of state opponents for sports with 6 Classes

    1.46 (the average of all 6 classes)

    Out of state opponents for sports with 5 Classes

    1.55 (the average of 2A through 6A)

    There is a one-time exception for a team playing down. That means, when a 3A team plays a 2A or 1A opponent for the first time on their schedule, that 2A or 1A opponent will count as a 3A team. Subsequent games against teams from lower classifications will count as their true classification. This modifier only comes into play when a team wins. Under the modified RPI system, each game is assigned a value based on that team's classification. Again, there is a 15 percent difference between them. So, for example, a 5A team will always have a game value of 1.749, regardless of who they're playing. The value of the win changes according to their opponent (unless the exemption comes into play). The result gives us a modified winning percentage. This is the number that will be used throughout the formula, including for their opponents, and the opponents of their opponents. So a team that goes undefeated but plays multiple teams below their classification may end up with a winning percentage of less than 100%.

    For example, a 5A team (call them Team A) plays another 5A team (Team B), and beats them. They then play a different 5A team (Team C) and lose to them. The third week, the play a 4A team (Team D), and beat them. Finally, they play yet another 4A team (Team E), and beat them as well. Here's what the calculation would for Team A look like:

    OPPONENT

    RESULT

    GAME VALUE

    WIN VALUE

    WINNING PERCENTAGE

    Team B (5A)

    W

    1.749

    1.749

    1.00

    Team C (5A)

    L

    1.749

    0.000

    0.00

    Team D (4A)

    W

    1.749

    1.749

    1.00

    Team E (4A)

    W

    1.749

    1.521

    0.87

    Now, Team A in this scenario is 3-1. Their true (unmodified) winning percentage would be 0.75. However, with this modified system, where their total win value (roughly 5.019) is divided by their total game value (6.996), their modified winning percentage is 0.717.

    Over the course of a season, if Team A were to go 9-1 with wins over all 5A teams the rest of the way, their modified winning percentage would be 0.887 (as opposed to a true winning percentage of 0.900). It is worth remembering that this number is 40 percent of the overall formula.

    The RPI is based on a win loss formula. Score differential will have no bearing on the RPI.

    The RPI formula works off the averages of three components: winning percentage, opponents' winning percentage and opponents’ opponents winning percentage, so an imbalance of one or two games between teams will have virtually no impact on the ranking system.

    The final RPI calculations used for seeding purposes will be based on the final records of all teams.

    OWP is the average winning percentages of a team's opponents. (Note: This is not calculated via the combined record of the opponents, but rather averaging each winning percentage of the opponents.) It is also important to remember that when calculating OWP (and OOWP), the head-to-head matchup between teams is taken out of the equation. That game already is figured in both teams' WP. The RPI rationale for omitting that is so there isn't a double bonus or a double hit for that specific game to the teams, and you get an accurate reading of how teams rate when they are not playing each other.
