INDIANAPOLIS, In. -- Washburn volleyball remained ranked No. 7 in the final NPI Central Region rankings prior to the announcement of the NCAA Tournament bracket next week. 

The NCAA Power Index (NPI) is a ranking system used in Division II and Division III to evaluate team performance based on game results and the strength of opponents. These factors are used to calculate each team's NPI value and ranking. 

Eight teams from the central region will advance to the NCAA Central Region Tournament with three automatic qualifiers up for grabs for conference tournament champions in the MIAA, NSIC and GAC. The top ranked seed among the eight schools will serve as the host site for the eight-team tournament. 

The Ichabods are No. 7 in the region with a No. 25 rank nationally. Wayne State (NE) is the top-ranked team in the region and No. 2 in the nation. Four MIAA schools sit inside the top-eight of the region with Nebraska Kearney, Emporia State and Missouri Western joining Washburn. 

The NCAA selection show will take place on Sunday, Nov. 15 at 9 p.m. and is live streamed on ncaa.com.
