What does course rating and course slope really mean?

While course ratings are a measure of the difficulty of a course, slope ratings are a measure of how much more difficult a course is for a high handicap golfer versus a lower one. For example, if you have two courses that each have a course rating of 72, they should be the same difficulty for a scratch golfer.

How is course rating calculated?

The Course Rating is calculated from the effective playing length and obstacle factors for 9 or 18 designated holes.

The team also considers a number of potential obstacles, such as sidehill lies, width of fairways, difficulty of hitting the green, difficulty of the rough, bunkers, out-of-bounds areas, water hazards, green speed and the number of obstacles close to a landing area, which the USGA labels the "psychological" factor.

Why Have Two Numbers?

What is the average scratch golf score?

It turns out that that statistically, no matter how easy or hard a course is, scratch golfers will almost always shoot in the high 60’s to low 70’s. While this might not seem like a big deal, having a very narrow spread of scores even on courses that are much easier or harder than average ones creates a rating that underestimates changes in course difficulties for the rest of the golfing population. However, they also realized that this phenomenon was the exact opposite for mid-high handicap golfers. While one course might only play slightly harder in the eyes of a scratch golfer, less proficient golfers might find their scores to be significantly higher on this new, harder course.

What is the role of slope in golf?

The most important role of a slope is leveling the playing field for players of different skill levels. For example, let's say Player A and Player B average 85 strokes each for 18 holes. But Player A's average is established on a very difficult course (say, a slope rating of 150), while Player B's average is established on a much easier course (say, a slope rating of 105). If handicaps were simply estimates of golfers' average scores, then these two players would have the same handicap index. But Player A is clearly the better golfer, and in a match between the two Player B would clearly need some strokes.

What is the minimum slope rating for 18 holes?

The minimum slope rating is 55 and the maximum is 155 (slope does not relate specifically to strokes played as course rating does).
