These ratings are based on the Bradley-Terry method. Ratings are compiled for NCAA FBS (Division 1-A) football and Division 1 basketball. The basic method considers only win/loss results and home field advantage; the margin-aware method is modified to use margin of victory as well with diminishing returns for blowouts.

Home field and a small adjustment to produce more realistic win probabilities for teams at the extreme ends of the rating scales have only been applied to the ratings starting with 2011 football.

Starting in 2014, a preseason adjustment based on the previous year’s rating is included early in the season. This adjustment is gradually removed as more games are played and eventually disappears entirely. It has no effect on the late-season ratings but should produce more reasonable early-season results. Ratings without the preseason adjustment will also be available for comparison. In addition, team pages are now available showing each team’s results.

Details of the method are available here.
