2024 National Collegiate Athletic Association Power Index (NPI) – Men’s Water Polo (October 13)
BRIDGEPORT, Pa. — The National Collegiate Athletic Association (NCAA) released the NCAA Power Index (NPI) for men’s water polo through games of October 13.
University of the Pacific leads the NPI with the University of California-Los Angeles, Stanford University, the University of Southern California, Fordham University, Pepperdine University, Harvard University, Princeton University, the University of California and the University of California-Irvine completing the Top 10.
The NPI is a system that houses the division’s statistical data and objectively applies the selection criteria to the data based on the sport committee’s established weighted criteria. NPI is a combination of the following: winning percentage; strength of schedule; home-away multiplier; quality win bonus; and overtime results (when relevant).
The weight of winning percentage versus strength of schedule is often referred to as one of the “dials” that a sport committee can adjust, placing any subjectivity within the criteria themselves. For example, a sport committee could set the dials to 30/70; 25/75, etc. Other “dials” a sport committee can also choose to apply are home and away multiplier, quality win bonus (QWB), and overtime win/loss weights.
The NPI was created due to the NCAA Championships Committee (which oversees all sports) reviewing the current team at-large selection process to ensure that selection criteria is applied consistently to teams during selections. The change from the current championships selection process to the NPI will take the data analysis from a subjective application, varying by sport committee, to an objective computer data analysis based on the weights established by each sport committee.
The following criteria will no longer be used by the NCAA: head-to-head competition; results versus common opponents;
results versus ranked teams; and secondary criteria. However, winning percentage and strength of schedule continue to be utilized in NCAA selections and seeding.
