RPI (Ratings Percentage Index)


This is the home for the Official KHSAA RPI calculations and results. This information is powered solely by data from the Sports Scoreboards.

Note: Any Kentucky High School RPI data displayed anywhere but or via its official Scoreboards should be viewed with skepticism and is likely inaccurate as that data is unofficial and not sanctioned by the KHSAA. The official KHSAA RPI data will be linked from this page.

RPI stands for “Ratings Percentage Index.” In short, it is a way to measure a team’s strength relative to other teams, based largely on the strength of their schedules. The RPI formula is used by both the NCAA and NAIA, along with many high school associations and among other organizations, as part of their postseason system. RPI is calculated from the team’s Winning Percentage (WP), the Opponent’s Winning Percentage (OWP) and the Opponents’ Opponents’ Winning Percentage (OOWP). The KHSAA is uniquely positioned to be the sole and authenticated source of RPI data due to the maintenance of required score reporting and scoreboard data for Baseball, Basketball, Field Hockey, Football, Soccer, Softball, and Volleyball.
