Course Rating™
The Foundation of Fair Handicapping
The driving force behind the USGA Handicap Index® formula is the Course Rating™ and Slope Rating®.
Overview
If the ratings don’t accurately reflect the playing difficulty of the golf course, Handicap Index® values will not travel well from golf course to golf course. All golf courses must be rated according to USGA Course Rating™ Procedures and only by amateur golf associations licensed by the USGA. A golf facility is NOT permitted to rate its own golf course.
AZ GOLF has been authorized and licensed by the USGA to rate golf courses in Arizona. Because Course Rating™ and Slope Rating® are so important to your Handicap Index®, this service is provided as part of a club’s membership with AZ GOLF.
The USGA requires all golf courses to be rerated at least once every 10 years. Because new courses change rapidly in the first few years, they should be rerated every five years for the first ten years of operation.
The Course Rating™ teams consist of a combination of AZ GOLF staff and volunteers. The process has become quite complex and requires individuals with an analytical nature. It generally takes a team of raters three to four hours to rate a course. Each hole is evaluated using the USGA Course Rating™ System guidelines from two different points of view: how it plays for a scratch player (a golfer with a Course Handicap™ of zero) and a bogey player (a golfer with a Course Handicap™ of 20 for men or 24 for women). In essence, they are trying to predict scoring for each of these groups of players.
Following the analysis and obstacle evaluation, the Course Rating™ team will normally play the golf course to clarify any doubts or questions that may come up on specific holes or shots.

Course Measuring
Despite the extensive evaluation of obstacles, golf course length still has the most impact on Course Rating™ and Slope Rating®. Having an accurate starting point is critical. The rating system requires that a hole be rated from an average tee location, typically the center of the teeing ground, to the center of the green. This allows for day-to-day variances in tee placements and hole locations. For this reason, it’s AZ GOLF’s policy to measure a golf course prior to the rating.
For several years, AZ GOLF has been using a Global Positioning System (GPS) to measure golf courses. AZ GOLF was the first association in the world to utilize this latest technology! It is still one of only a few associations that have adopted this method.
The measurement of golf courses is part of the services the Course Rating™ Department provides to member clubs. This service includes a club’s overall yardage from every set of tees and the driving range. Measurements are available for new courses and changes to existing courses.
