Ratings through the 2015 Illinois high school football season. uses a computer model to provide an objective comparison of the high school football teams
and conferences in Illinois. To create our lists, we use software that was originally developed as an alternative to the NCAA
Bowl Championship Series methods and we apply it to all 579 high school football programs in Illinois. On these pages,
you can find single-season and multiple-season ratings. We recommend that you look at the multiple-season ratings first.
Because of the large number of schools involved, and because of the vast differences between 1A and 8A schools, this
computer model is at its best when dealing with broader trends involving many seasons. The more data it has, the better it

To do the calculations, we chose the
Wilson Performance Ratings, developed by David L. Wilson, a mathematician at the
University of Wisconsin. Wilson's method provides a simple and mathematically sound way to quantify the toughness of a
school's schedule and its propensity for winning.

We invite you to take a look at the numbers and decide for yourself. If you have questions, criticisms, or find an error in
