In the National Football League (NFL), quarterback passing proficiency is evaluated using a formula called passer rating. The NFL has used passer rating to determine its official passing leader since 1973. Passer rating in the NFL is on a scale from 0 to 158.3. Quarterbacks are required to throw at least 1,500 passes before their ratings qualify for NFL career statistics for the regular season, and 150 attempts for the postseason.
