Golf's handicap system: A beginner's guide

A golfer is asked what his handicap is. His reply: "my golf game."

It's an old joke but it really is a loaded question.

When you're playing golf with people you've never played with before, the question about a handicap is a common one. And because only 20 percent of all golfers have legitimate handicaps, the answers, whether the golfer is trying to be truthful or not, are often without merit.

Most golfers who don't have a handicap just guess their average score and subtract 72 from it. That's not a handicap.

And even those who have a real USGA or R&A handicap index, because of the way handicaps are reported nowadays, can fudge their way to being a sandbagger (but that's a different discussion).

Fortunately, in many tournament settings there are certain safeguards to look out for with handicaps. For example, if you play in the Golf Channel Am Tour, your handicap will land you in a certain flight, but your tournament scores on the Am Tour carry far more weight. Shoot a few low scores or win a couple of times, and you're likely to get bumped up to more skilled flight. In fact, the national champion in each flight, except at the championship level, automatically moves up to the next flight the following season.

In an ideal world, of course, everybody reports their actual scores and makes the proper adjustments and there's little need to intercede.

But to get a better understanding of what a handicap should be and how the system works, let's take a look:

A brief look back at golf handicaps

Handicaps in golf are almost as old as the game itself, though they certainly weren't administered the way they are today. In the mid-1800s in Scotland it was simply a matter of matching the lesser player against the more accomplished player. The terms "third-one" or "half-one" came about, meaning that the lesser player would get a stroke every three or two holes, respectively. The assigning of these "odds" often came at the discretion of individuals competing or a committee, but courses weren't rated yet, so this method didn't travel from course to course.

By the late 1800s golfers started getting handicaps for tournaments. One method involved computing the average of the best three scores of the year and subtracting par from that average. Critics argued that such a method clearly favored the better players, and that was certainly true. Today a variation of that method still exists because handicaps really aren't your average; they are a measurement of your potential, but we'll get back to that later.

In order for handicaps to travel, however, courses had to be rated. In other words, not all courses are created equal. Basically a course rating is the reflection of what a scratch golfer would shoot on that course. If it's a particularly difficult track, the course rating could be 75 or 76, playing two or three strokes over par for scratch players. Chambers Bay, which hosted the 2015 U.S. Open, rates 76.6 from the back tees with a slope rating of 140.

Slope, by the way, didn't really come around until 1979 when Dean Knuth (he was a Navy commander then) invented the formula to predict what bogey golfers would shoot on a course on a particular set of tees. Regarded as the world's foremost authority on course ratings and handicaps, Knuth was the United States Golf Association's Senior Director of Handicapping, GHIN and Green Section Administration from 1981-97.

"By comparing the bogey rating to the scratch rating, I was able to develop the Slope Rating for each course -- a way to predict how fast scores go up as the golfer's handicaps go up," Knuth wrote on his Web site, popeofslope.com.

Course and slope ratings aren't just used to determine handicaps; they are also used to adjust a person's handicap when they travel. Without going into the formula, suffice it to say that when a course is harder than average, a player will get more strokes than his or her handicap at a tournament at said course. If the course is easier, it's fewer strokes.

How is a handicap calculated?

Individual handicaps are determined by a formula that takes your adjusted score (when you first set up your handicap, triple bogey is maximum on each hole) and subtracts the course rating. That figure is then multiplied by 113 (which represents the slope rating of a course of average difficulty) and divided by the actual course rating for the selected set of tees.

It might look like this if you shot 82 at Chambers Bay from the back tees: (82 minus 76) X 113/140. In this example, your differential would be 4.8, which is far lower than the actual score of 8-over par.

You can establish a handicap by entering as few as five scores, but only the lowest differential would be used to determine you handicap. In the above example, your other four scores could all be more than 100, but you'd still carry a handicap index of 4.8. That's why, of course, you want to enter all your scores. Once you get to 20, the average of the 10 lowest differentials of your last 20 scores are used to determine your handicap. That figure is multiplied by .96, and that's your handicap index.

How to get a handicap

This is the easy part. You can either sign up for one at your home course or register for a GHIN (Golf Handicapping & Information Network) handicap with your local golf association connected with the USGA. I have mine at Memorial Park in Houston, though most of my rounds are on the road. I pay $33 a year for this service.

In the old days, you used to turn in your scorecards to your pro. There was more review back then, making it more difficult to fudge the numbers. Nowadays with the Internet and computers, golfers usually just enter their own scores into the GHIN system and like golf itself, integrity is a big part of the process.

It's certainly not necessary to know the handicapping formula, but the basic understanding of it will help you in your matches and tournaments with other players, especially against those who really don't have handicaps and are just guessing based on what they think their average score is.

At our club we have an issue with members not entering scores in to the GHIN system.
Which scores need to be entered?
> Tournament Play
> Men's Association Group Play
> Friendly Golf Group
> Random Individual Play ( If played according to the rules of golf )
> Practice Rounds

My current handicap is 28. Is there a rule about entering a maximum score on a given hole as one totals his or her score for the round?

Question, I was told you take lowest 10 scores out of your last 20 and then multiply by 113. OK, I understand that part but I was also told you take your lowest 2 tournament scores but I don't understand how that works to get your handicap. Right now my GHINS is 9.3R and my two tournament scores are 74 70.3/128 and 76 69.0/125. Could you explain the tournament scores and how they are figured in?

Is this even legal?? Our home course has three holes where you tee off over water. One of the ladies in the league "was tired of losing balls in the water" so she had her handicap reconfigured with her teeing off from the gold tees (the drop zone). She now hits from there, but incurs no penalty strokes. She is hitting one from the gold tees (not age eligible for our club) and I am hitting one from the red tees and over the water. It just doesn't feel right, regardless of how many balls she has lost. Shouldn't she be taking a penalty stroke of some kind for this???

I am troubled that my handicap is the same from 5 different sets of tees. Our championship course is 1,500 yards longer than our senior course, yet, my handicap is the same. How is that possible?

they should NOT be the same; each set of tees SHOULD have their own different slopes

I've been told you never score more than a double bogey if your handicap is 18 or less and I've also been told you never score more than a 7 no matter what the par.  This of course is for recording you score for handicapping, not for tournament score.  Are either of these correct?

What you are referring to, according to the USGA, is equitable stroke control, which sets a maximum number that a player can post on any hole depending on the player's course handicap. Mind you, it's the course handicap, not personal handicap index, which means depending on the difficulty or ease of the golf course you're playing, your handicap is adjusted slightly up or down for the course. So if you're a 9 handicap, for example, playing a tough course, your course handicap could be an 11 or 12.  Anyway, with that said,there's a chart that outlines the maximum number of strokes you can take on ahole depending on your course handicap. Players with a 9 or less can only take a maximum of double bogey. Handicaps 10-19 max out at 7 on any hole; 20-29, the max is 8; 30-39 the max is 9; and 40 or greater, it's 10.

How is the handicap calculated when players are using different tees? Two players both with 4.8 index and playing a new course, would not even. or would they?

Here you go, from an article I did a while back on that very topic:Basically, here's the formula: Take the player's handicap and multiply it by the course's slope rating for those tees, then divide it by 113 (USGA determined average slope), then add the course's rating for those tees. That gives you the score that the player is expected to shoot if he plays to his handicap. (In case you're interested, the USGA determines slope rating by taking the bogey rating (which could be 90 or so) minus course rating multiplied by 5.381 for men and 4.24 for women.)For example, if a 10-handicap plays from the white tees where the rating/slope is 68.3/121, the formula says the expected score should be almost exactly 79 (10 X 121 = 1,210, 1,210/113 = 10.7, 10.7 + 68.3 = 79). If you take a 7-handicap who plays from the blue tees where the rating/slope is 71.3/129, guess what? Yep, the answer is 79.29.Most of the time, there's no need to adjust for tees since that's already done in the handicapping process.
