09/17/21 – Initial RPI Rankings Released for Field Hockey, Soccer and Volleyball

September 17, 2021 2021-2022 News Releases


FOR IMMEDIATE RELEASE: September 17, 2021

The first official KHSAA Ratings Percentage Index (RPI) standings for the 2021 field hockey, boys’ and girls’ soccer and volleyball seasons have been posted at

Football’s RPI rankings will be released for the first time on September 20. Due to the limited number of contests for football compared to the other sports and the application of RPI data on a much more extensive basis as the office maintains the district standings, there will be additional clarification and operations in football that are not necessary in other sports.

The RPI ( is a tool developed for all team sports by using the official KHSAA/Riherds Scoreboard data. It is provided for a variety of reasons, including district tiebreaking and bracketing in specific sports, as well as a means to increase publicity, interest and promotion. 

The Board of Control has also approved that the RPI is to be used as a tiebreaking/contest result mechanism to decide seeded district games not played by the deadline due to pandemic or other reasons.

The RPI rankings are updated on an hourly basis, but are not calculated for teams with missing one or more scores from the previous day or earlier. 

COVID-related considerations and scoreboard notes:

  • Please note that different from the last academic year, in all sports, there is no longer a waiver of forfeits due to COVID cancellations.
  • Contests marked on a team’s schedule as a COVID cancelation will have a 1-0 or 0-1 score which is factored into the RPI calculations as any other win or loss, based on which team is unable to fulfill the scheduled contest.
  • For field hockey, soccer and volleyball, in the event that there is a mutual COVID cancelation (both teams in quarantine) the score will be recorded as a 0-1 loss vs. NA for both. The NA opponent will be assigned a .50000 winning percentage, which is the average value of opponents’ opponents winning percentages across all sports as explained in the out-of-state section below.

RPI measures a team’s strength relative to other teams, based largely on the strength of their schedules (margin of victory is not a factor). RPI is calculated from the team’s Winning Percentage (WP), the Opponent’s Winning Percentage (OWP) and the Opponents’ Opponents’ Winning Percentage (OOWP). These three components are combined to produce the RPI using the following formula: RPI = (WP * WPVAL) + (OWP * OWPVAL) + (OOWP * OOWPVAL).

The RPI uses the following final calculation:

  • WPVAL shall be .35 (or 35 percent)
  • OWPVAL shall be .35 (or 35 percent)
  • OOWPVAL shall be .30 (or 30 percent)

All out-of-state opponents will be handled in the following manner:

  • All out-of-state teams will be assigned a .50000 WP for all calculations. Were this not the case, schools would be chasing tens of thousands of opponents of out-of-state opponents over the course of a season, and there is no way to ensure the accuracy of that data.
  • The .50000 figure was selected because it is the average value of opponents’ opponents winning percentages across all sports.
  • This same value of .50000 is also assigned to any in-state home school competing against a member school.
