Below are listed the current NCAA FBS college football ratings as computed by the Donchess Inference Index. More information on how these NCAA computer ratings are computed can be found on the Methodology page and we do our predictions on each game at College Football game predictions.
DII Rating– This is a NCAA football ratings system that is a combination of the Standard Rating and the Aegis Rating. The Aegis Rating is weighted more highly in the beginning of the season whereas the Standard Rating is weighted more highly at the end of the season. This is the final rating that is used to rank the teams. We also use the Vegas Rating to help create our preseason rankings, but these place a much lesser roll as the season goes on.
Standard Rating– Looks at game outcome, date and score differential only. Record is the most important factor in this rating system. Further, this rating system is heavily based on the outcomes of games in the current season and is totally based on that come season end. This rating has the least amount of bias and shows what teams are “most politically correct” to make the top 4 playoff.
Aegis Rating– Replacing the Inference Rating, this uses mostly the same the same criteria as the Standard Rating, but heavily weighs the margin of victory of the game. Data from previous seasons weighs into this algorithm (especially, early in the season). This is system is a much better predictor of future game outcomes.
Vegas Rating– This is our newest rating. The Vegas rating takes into account what the Vegas line on each game is. More recent games are weighed the most heavily, and outcome and score differential are also of factor. This rating system is also a very good predictor of future outcomes. Overall, this rating tells us which teams are the best regardless of win-loss record.
It’s also important to note that the ratings early in the season are very unstable as there is not a lot of data on the games yet.

Top Conferences in College Football – Top to Bottom
The “top to bottom” approach gives the simple average of the rating for every team in the conference. In my opinion, this is the best and most unbiased way to rank conferences.
