The Importance of Course And Slope Rating
Full Answer
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.
The slope rating of a golf course is a measure of its difficulty for bogey golfers. The term comes from the likelihood that when playing on more difficult courses, players’ scores will rise more quickly than their handicaps would predict. The “slope rating” of a course thus predicts that rise.
While the course rating indicates the difficulty of a course for a scratch golfer, the slope rating, by contrast, indicates how difficult the course should be for a bogey golfer (or someone who averages +18 for 18 holes). Also unlike course rating, slope values can range from 55 to 155 with 113 being the average.
Slope rating (a term trademarked by the United States Golf Association) is a measurement of the difficulty of a golf course for bogey golfers relative to the course rating. Course rating tells scratch golfers how difficult the golf course will be; slope rating tells bogey golfers how difficult it will be.
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.
The Course Rating is calculated from the effective playing length and obstacle factors for 9 or 18 designated holes. The Course Rating is expressed in strokes to one decimal point and represents the expected score for a scratch player. The Bogey Rating represents the expected score for a bogey player.
If you are playing a course with a slope in the 130's, you might want to aim for something under 95 as opposed to 90. On the other hand, a course with a slope in the low 100's may allow you to aim for an 85 – or even lower.
Slope Ratings range from 55 to 155, with the average being 113. When you play a course with a Slope Rating higher than 113, your Course Handicap will be higher than your USGA Handicap Index. When you play a course with a Slope Rating lower than 113, your Course Handicap will be lower than your Handicap Index.
The middle tees are for middle to high handicap men, low-handicap or long-hitting women, and low-handicap or long-hitting senior men. The forward tees are for middle or high handicap women and seniors, and beginners of all stripes.
What Is A Good Golf Handicap? A good golf handicap is ten or less. With a handicap index of ten or less, you will generally shoot somewhere around 82. Shooing in the low 80s is better than average but certainly not good enough to be considered a scratch player.
From Tom's tees, a slope of 130 gives him a 12 Course Handicap.
Slope ratings are calculated as a multiple of the difference between the expected good score for a bogey golfer (handicap in the range 20 to 24), called the bogey rating, and the expected good score for a scratch golfer (zero handicap), called the USGA Course Rating.

The higher the slope number, the harder the course is for the bogey golfer relative to the difficulty of the course for the scratch golfer. Slope numbers can range anywhere between 55 and 155 with the average slope in the United States being 120.

The average slope rating is 120, according to Dean Knuth, also known as “the pope of slope,” the man who invented the system in 1982. In conclusion, course ratings and slope ratings are useful and objective measures of golf course difficulty.
Authorized by golf associations and using USGA standards, course rating teams closely study a golf course and collect a lot of data, including on each hole.
A female scratch golfer can hit 210-yard tee shots on average and reach a 400-yard hole, at sea level, in two shots. Meanwhile, the USGA says bogey golfers have a course handicap of 20 for men and 24 for women on golf courses of standard difficulty. Average yards off the tee are 200 for men and 150 for women.
This begs another definition. Namely, the bogey rating. In a nutshell, it’s the playing difficulty of a golf course for a bogey golfer.
And what is a scratch golfer? According to the USGA, a scratch golfer is a man or woman who can play to a course handicap of zero on all rated golf courses. In others words, he or she can shoot a score that nearly matches the course rating from his or her designated tees.
One thing that makes golf different than other sports is the “playing field.”. Whether long or short, hilly or flat, no two golf courses are alike. And while they’re all challenging in their own way, some golf courses are harder than others. In fact, some courses are like childhood bullies who will steal your lunch money ...
Plus, courses change, which is why they must be re-rated at least every 10 years.
Slope rating (a term trademarked by the United States Golf Association) is a measurement of the difficulty of a golf course for bogey golfers relative to the course rating. Course rating tells scratch golfers how difficult the golf course will be; slope rating tells bogey golfers how difficult it will be. To put it another way: USGA Course Rating ...
The minimum slope rating is 55 and the maximum is 155 (slope does not relate specifically to strokes played as course rating does).
The minimum slope rating is 55 and the maximum is 155 (slope does not relate specifically to strokes played as course rating does). The higher the slope, the more difficult the course is. When the slope rating system was first put into effect, the USGA set the slope for an "average" golf course at 113; however, not many 18-hole golf courses have slope ratings that low. Some do, but the real-world average is higher than 113. (However, a slope of 113 is still used in certain calculations within the handicap system.)
USGA Course Rating is an evaluation of the difficulty of a golf course for scratch golfers. (More specifically, the number is an estimate of the average scores of the best 50-percent of rounds played by scratch golfers at the course being rated.) Course rating is very easy to understand because it is expressed in strokes.
Course rating is very easy to understand because it is expressed in strokes. A par-72 course that is easy might have a course rating of 68.9; one that is difficult might have a course rating of 74.5. That means that a scratch golfer should be expected to average 68.9 strokes in his better rounds at the easier course;
While frequently unused by new or casual golfers, slope and course rating are two of golf’s most important, and most commonly confused numbers. These two numbers might be a seemingly random arrangement of numbers on your scorecard, but in reality , they are two of the great equalizers in the game of golf.
While the course and slope ratings of a golf course are unlikely to change dramatically, they are usually re-evaluated every 4-5 years.
This scorecard shows the course rating (first number) and slope rating (second number) for each set of tees at a course.
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.
If you’re interested in calculating your handicap for a particular course, multiply your handicap by the course rating divided by 113. This will adjust your handicap to the difficulty of the course.
These two factors of change, both physical change and increased experience, frequently work against each other and often times nearly cancel out most changes in ratings, however, the possibility is always there. Although many of us spend very little time considering the ratings of courses we play, looking at courses through a different lens, such as how a scratch versus bogey golfer might play a hole, is actually a great way to improve your course management skills.
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. However, if bogey-golfers on course A averages a score of 90 while bogey-golfers on course B average a score of 95 the slope rating for course B would be higher than for course A; indicating a higher level of difficulty for higher handicap players.
Course and slope rating are both used in determining a handicap differential. The course rating is an estimated average score for a scratch golfer. It’s usually a number between 67 and 77. Slope Rating is also an estimated average, but it’s for what an average or bogey golfer would shoot on that course. Let’s take a look at slope rating in action:
Slope Rating [Infographic] A golf course’s slope rating is listed on their score card, along with the par for that course and the course rating. These numbers are intended to help golfers determine the difficulty of the course. Course and slope rating are both used in determining a handicap differential.
A Course Rating represents the expected score for a scratch player (Handicap Index of 0.0) under normal playing conditions, while a Bogey Rating represents the expected score for a bogey player (Handicap Index 20.0 to 24.0). These two figures work together to calculate a Slope Rating, which is a measure of the relative difficulty of a golf course between the scratch player and all other players. In other words, the higher the Slope Rating of a golf course, the more strokes a higher-handicapped player will need to play that course on an equal basis to the scratch player.
By including a unified system for Course Rating under the WHS, a player can use their Handicap Index at any course, in any country, and have a fair and equal game with anyone, from whichever tees they most enjoy.
Therefore, the course rating provides scratch golfers information about the course difficulty, while the slope rating delivers the same information to bogey golfers. In other words, the USGA slope rating indicates the additional playing difficulty of the course for average golfers compared to scratch players. The dominant factor that defines the course difficulty is the golf course rating, not the slope rating.
The United States Golf Association established the average slope rating to 113, but it has later increased to about 120 as there aren’t many 18-hole golf courses with slope ratings set that low. As has been observed, most golf courses worldwide have average slope ratings of about 120.
USGA Golf Course Rating is an assessment of the difficulty of a given golf course for scratch golfers. The course rating estimates the scratch golfers’ average scores who played on the golf course under the rating procedure. It is expressed in strokes, so an easy par-72 golf course could have a 68.9 course rating, while the more difficult one is likely to have a rating of 74.5.
The minimum established number for a slope rating is 55, while the maximum is 155. The difficulty is proportional with the number, i.e., the lower the slope rating, the less difficult it is. The United States Golf Association established the average slope rating to 113, but it has later increased to about 120 as there aren’t many 18-hole golf courses with slope ratings set that low. As has been observed, most golf courses worldwide have average slope ratings of about 120.
The standard procedure to calculate the slope rating is to multiply the difference between the bogey rating and the USGA score rating. The score you get when the expected good score for a Scratch golfer (a zero handicapper) is multiplied by the expected good score for a bogey golfer (a Mid handicap golfer with a range from 18 to 30).
When rating the course, the team evaluates the landing area for a bogey golfer the first 200 yards off the tee. They measure the width of the fairway, consider any existing bunkers, and estimate the distance from the fairway center to the nearest boundary/hazard line or trees. The same measurement is applied for scratch golfers, adding 50 yards to the landing area off the tee. The process continues until the team reaches the green. There, the rating team measures the depth and the width of the Putting green, the bunkers and the water hazards, and the distance to the boundary line.
Thus, the slope number converts a golfer’s handicap into a course handicap. In this way, it is made sure that a bogey golfer is allowed to play at an equal level to a scratch golfer, and it helps them obtain enough strokes from the same set of tees. This is the mathematical formula of how it is derived:
You calculate slope rating by finding the bogey rating, which is like the course rating, but measured for a bogey golfer. Then subtract the course rating from that figure. Then multiply that figure by 5.381 for men and 4.24 for women. Then round up to the nearest whole number.
A golf course rating tells you what a scratch golfer would be expected to shoot from the tees they're playing on a particular course under normal conditions. The rating is different for men and women.
The golf course slope is a measure of a course's difficulty, but it is not considered the better of the two measurements. Golf course slope is actually derived from the golf course rating. Slope is a measure of a golf course's difficulty in a relative comparison of a scratch golfer to a bogey golfer (someone who shoots around 90 for 18 holes).
A male scratch golfer, for rating purposes, can hit tee shots an average of 250 yards and can reach a 470-yard hole in two shots.". A scratch woman can "can hit tee shots an average of 210 yards and can reach a 400-yard hole in two shots at sea level.".
Course slope is a figure that indicates the difficulty of a course in relation to a golfer who averages a bogey on every hole, and therefore, averages 18-over par on any given round.
Course rating is a figure that indicates the difficulty of a golf course to a golfer who averages even par on a round of 18. For instance, a course rating of 72 would portend that a "scratch golfer" would shoot 72 on that particular course.
Course and slope rating can impact final scores in scramble tournament play.
Handicap is a number assigned to a golfer, indicating the number of strokes over par they are on an average round of golf. For instance, a golfer with an 18 handicap would typically shoot 18-over par during a round of 18 holes. On a course with a course rating of 72, this golfer would be expected to shoot 90. Meanwhile, a golfer with a 20 handicap would be expected to shoot 92 on this same course.
