The CHSAA selection and sowing index for spring 2025 is now available. Display all rankings for all classifications on the Sowing and selection center.
The sowing index is calculated by making the score of each team in the Chsaa RPI and in the Maxpreps ranking. These notes are standardized in their classification, then combined and averaged. Answers to the questions frequently asked about the sowing index, including an explanation of the way in which standardization is calculated, can be found on the FAQ page of the seed index.
During the regular season, RPI data is updated every hour and Maxpreps data is updated on Monday and Thursday. Once the regular season is completed, the data will be finalized and frozen.
More detailed data on each classification system is available on their pages:
