According to the NCAA, “the Rating Percentage Index (RPI) is a statistical tool that measures the strength of a team’s performance based on their wins and losses and their strength of schedule.” The RPI is used to help determine which teams get selected for the NCAA Tournament at the end of the season. The RPI rankings are updated weekly throughout the season, with the final rankings released just before the selection show.
As former NCAA Division I baseball coach, Tim Parenton, stated, “RPI is a very important analytical tool, as it gives you a picture of what needs to happen in your upcoming games to either increase or maintain those rankings.” Coaches and players alike closely monitor their RPI ranking throughout the season, as it can make or break their chances of making it to the NCAA Tournament.
