Another week of the 2025 Iowa high school football season has come and gone, and High School On SI has all of the latest rankings for each classification as of September 15, 2025.

High School On SI's formula was created using its own 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 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 25 — released early each week.

Which teams took the top spot in each division? Here are High School On SI's latest Iowa high school football computer rankings, as of September 15, 2025:
