Passer rating is a tackle football statistic that is used to evaluate a quarterback’s passing performance in the NCAA (National Collegiate Athletic Association) League. A different formula is used to calculate Passer Rating in the NFL and CFL.
It is intended to mix some different indicators into one “aggregate” rating to show a quarterback’s overall passing performance.
There is an upper limit to the statistic of 1,261.6 and a lower limit of -731.6.
Passer Rating as a measurement of a quarterback’s effectiveness was implemented in the 1970s.
The system was developed by the NFL’s statistical committee to replace an existing system that ranked a quarterback’s performance relative to their peers. The NCAA adopted the concept into a separate formula.
In NCAA Football, passer rating is calculated as follows:
NCAA Passer Rating = ((8.4 x Passing Yards) + (330 x Touchdown Passes) + (100 x Number of Completions) – (200 x Interceptions)) / Passing Attempts
If a quarterback has made 659 passing attempts and in that time has 450 completions, has passed for 5,477 yards, made 55 touchdown passes, and has had 10 interceptions, then:
NCAA Passer Rating = ((8.4 x 5477) + (330 x 55) + (100 x 450) – (200 x 10)) / 659
NCAA Passer Rating = (46006.8 + 18150 + 45000 – 2000) / 659
NCAA Passer Rating = 107156.8 / 659
NCAA Passer Rating = 162.61
Therefore, the quarterback’s passer rating in the NCAA league is 162.61
