Week 4 of the 2024 Iowa high school football season is in the books, and High School on SI is debuting its first computer rankings of the season.

Starting the season with a big Top 100 win against Pleasant Valley, the Bettendorf Bulldogs lead the way for the 5A computer rankings. Pella holds the edge in the 4A race after a thrilling victory over Xavier. Class leaders Bettendorf and Pella hit the road this Friday in attempts to keep their unbeaten streak alive.

SBLive's formula was created using its linear algebra-based ranking algorithm inspired by the Colley Bias-Free Ranking Method. Colley’s Method was created by Wes Colley, Ph.D., an astrophysicist at the University of Alabama at Huntsville. He devised his algorithm to help address the subjectivity and controversy regarding BCS college football selections in the 1990s and early 2000s, using a method that used no subjective variables.
