Slope Rating represents the relative difficulty of a course from a specific set of tees for a 'bogey golfer' compared to a 'scratch' golfer. A course with long carries and thick rough will have a high slope rating because these features are more of a challenge to bogey golfers.
Mapperley's Slope Ratings are:
- White tees (men) 127
- Yellow tees (men) 123
- Red tees (men) 117
- Red tees (women) 128
A golfer's handicap for a specific course is determined by multiplying the player's Handicap Index by the ratio of the course Slope Rating divided by the neutral Slope Rating of 113. For example, from the White tees at Mapperley, Course Handicaps will be calculated as follows:
- A 10 Handicap Index golfer will have a Course Handicap of 10 x (127/113) = 11
- A 20 Handicap Index golfer will have a Course Handicap of 20 x (127/113) = 23
- A 30 Handicap Index golfer will have a Course Handicap of 30 x (127/113) = 34
- A 40 Handicap Index golfer will have a Course Handicap of 40 x (127/113) = 45

The sloping lines on the graphs in the 3rd and 4th pictures show why the term 'Slope' is used.
When the Slope Rating system is implemented it will make it easier to run competitions from different sets of tees - it would be possible to stage competitions where players nominate whether to play from White, Yellow or Red tees - their Course Handicaps would be adjusted accordingly and there would be an adjustment to the way that the results are calculated to reflect the difference in Course Ratings.
