The WIAA used RPI to seed the state basketball tournaments for the first time this year, and it could add it to football, soccer, volleyball baseball and softball after a trial year.
The Washington Interscholastic Activities Association is moving toward using Rating Percentage Index (RPI) to seed state tournaments for all team sports starting in the 2018-19 school year.
The WIAA approved the move at its Executive Board meeting last Saturday.
The WIAA used RPI to seed the regional and state basketball tournaments last season, its first use of such a system.
“For the most part, the coaches were really receptive and the fans really liked it,” WIAA executive director Mike Colbrese said.

A similar survey issued before the changes in the state basketball tournament found about 70 percent in favor.
The committee will still generate RPI reports, which it gets from Maxpreps.com, through the 2016-17 school year to study how it does in relation to the on-field product and report back to WIAA member schools.
Changes can be proposed and the ultimate decision on whether each sport adopts RPI can be made based on the information gathered.
“Nobody wanted to pull the trigger on it this year,” Whitmore said.
