WHS: WORLD HANDICAPPING SYSTEM
Course Rating & Slope Rating
Course Rating represents the difficulty of a golf course for a scratch golfer (0 Handicap Index), calculated to the nearest 0.1
Slope Rating represents the relative difficulty of a course for a bogey golfer (20 to 24 Handicap Index) compared to a scratch golfer.
A course with long carries, narrow fairways, lots of hazards and thick rough will have a high slope rating because these features are more of a challenge to bogey golfers.
Slope Rating can be anywhere between 55 and 155, 113 is the neutral value that is used in handicap calculations.
