Active Power Ratings The Active Power Rating is a number computed for every team such that if you sum the difference of the power ratings between a team and all it's opponents and add in a home-field advantage for each game, the result is exactly equal to the sum of the margin of victory or loss for each of the games played for that team. Another interpretation of the power rating is that based on past game scores, if two teams played each other on a neutral field the margin of victory or loss will, on average, be equal to the difference in power rating between these two teams.

Ranking We use the Active Power Ratings to rank teams within a state according to their playoff class and across states in a SportsPower class. This means that small schools are ranked with small schools and large schools are ranked with large schools. You can see teams ranked by their power rating within the state playoff structure and then between states by selecting a regional or national view.

SportsPower Classifications Each state has its own system for classifying schools into championship groups. Unfortunately this makes it difficult to compare teams between states in peer groups. SportsPower has defined 4 classes based on school enrollments so that approximately 25% of all of the teams are in the Mega, Large, Mid or Small class. We can then easily rank teams using their power ratings across states by using the SportsPower Classification and ensure that teams are ranked fairly.
