Another week of the 2025 Idaho high school football season has come and gone, andHigh School On SI has all of the latest rankings for each classification as of September 22.

High School On SI’s formula was created using its own linear algebra-based ranking algorithminspired 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 in order 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.

Our computer rankings run parallel to High School On SI’s expert power rankings–the statewide Top 15— released early each week.

The No. 1-ranked team in the all-classification High School On SI Idaho Top 15 is also the No. 1-ranked team in our 6A computer rankings, Rocky Mountain.
