The IHSAA began using RPI in 2018 to determine its at-large playoff qualifiers. Below is an explanation of the system. District champions across all six classifications receive automatic qualification into the playoffs.
The IHSAA’s RPI Formula
Teams will receive RPI numbers ranging between .0000 and 1.000 (higher is better) through three criteria weighted at different percentages.
-Your Own Winning Percentage (37.5%)
-Your Opponents’ Composite Winning Percentage (37.5%)
-Your Opponents’ Opponents’ Composite Winning Percentage (25%)
So, RPI = (.375 x WP) + (.375 x OWP) + (.250 x OOWP).
Three-Way District Ties
New in 2019, only one champion will be named out of each district. Two-way ties are broken through head-to-head competition, but with any true three-way ties for district championships, the automatic qualifying spot as district champion will go to the team with the highest RPI. The other two teams will reenter the at-large field and may qualify for the playoffs through RPI.
