RPI (Ratings Percentage Index)

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

Note: Any Kentucky High School RPI data displayed anywhere but khsaa.org or via its official Riherds.com/KHSAA 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 their own success and their strength of their schedules. A version of 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, accurate 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.

The RPI will be released each season at the start of the fifth playing week, and will be calculated for the regular season only. Any edits to the schedule of a team after the calculation of RPI has stopped for that season will not result in additional adjustment or recalculation.
