In 1979, the NCAA developed the passing efficiency formula using average statistics from the previous 14 seasons of two-platoon football.

The rating ranges from −731.6 to 1261.6 and is calculated using the following formula:

{ (8.4 * yards) + (330 * touchdowns) – (200 * interceptions) + (100 * completions) } / attempts }

Among SuperWest players, Oregon’s Marcus Mariota leads the way with a rating of 171.8, followed by USC’s Caleb Williams, a 2023 addition, at 169.3.

A pair of Boise State quarterbacks, Kellen Moore (169.0) and Ryan Dinwiddie (168.9) rank third and fourth, respectively.

In addition to Williams, Oregon’s Bo Nix (149.6) and Washington’s Michael Penix Jr. (146.6) joined the SuperWest Top 50 list in 2023.

Below you’ll find an updated ranking of career leaders in Career Passing Efficiency Rating through 2023 with rank, years played, and school, as well as a breakdown by program.
