The World Handicap System

The World Handicap System (WHS) goes LIVE on 2nd November, and every golfer needs to understand its impact on handicapping.

Here are some resources to help Members understand how the new system will work.


Course Assessment

To prepare for the introduction of the new system, our course has been assessed, and is based on how a scratch golfer would view the course.

RGC Ratings are Blues XX, Whites XX, Yellows XX and Reds XX.


Slope Rating

This rating represents the relative difficulty of a course for a bogey golfer as compared with a scratch golfer.
In this context, bogey means a 20 handicap for men and 24 for women. Slope Rating has been set separately for each tee colour.

  • Slope Rating will be higher on a course with long carries, narrow fairways, thick rough, etc.
  • Slope Rating falls within the range of 55 and 155
  • In GB & Ireland the average Slope rating is 125
  • For Handicap purposes, a Neutral Slope rating of 113 is used

RGC's Slope Ratings are:

Blue tees – xxx
White – xxx
Yellow – xxx
Red – xxx


Your Handicap Index

As a Member, you currently have a playing handicap. Under the WHS you will have a "Handicap Index" instead.

This will be computed as the average of the best 8 of your last 20 qualifying scores posted since 1st January 2018. If you have not posted 20 qualifying scores since that date, a method similar to allocating a new handicap will be used.

NOTE: The more cards submitted before 2nd November, even if they are just supplimentaries, then the more likely that on transition to the WHS, your new Handicap Index will reflect your current playing level and form.


Course Handicap

So, our course at RGC has been assessed, and we have our Slope Ratings. Members will soon learn about their personal Handicap Index.

Your handicap on a specific day is calculated by reference to the particular course and tee that you are playing from. This is the same process whether playing at home, or elsewhere.

Your Handicap Index is multiplied by the Slope Rating for the course and tee, and then divided by the Neutral Slope Rating of 113.

For example, if the Slope Rating of the Blue tees on a particular course was 127, then your Handicap Index is calculted as follows:

10.0 then 10 x 127 ÷ 113 = 11.2 will be your Course Handicap for the day.
20.4 then 20 x 127 ÷ 113 = 22.5
29.6 then 30 x 127 ÷ 113 = 33.7.       Etc.

Good News!  Charts will be available at all clubs, and in the PSI software used on the club terminals and phone Apps will take the strain, so you will not need to do this calculation yourself. Our chart is on the wall next to the door to the Pro's Shop.

N.B. It is your Handicap Index that must be recorded on your scorecard.


Submitting Scores

On completion of the round, as soon as possible on the day, you must post your scores electronically on the PSI of the club you played at. If using phone Apps, scores must be posted before midnight. Your Handicap Index will be updated in the “Cloud” at 5 minutes past midnight. There will be sanctions for non-submission of scores.

Please also register for your England Golf account at  Do do so, you will need a valid email address which RGC knows about.

By signing up you can also receive the England Golf WHS newsletters directly to your inbox.

From the 2nd November you can also track your handicap through the England Golf WHS Platform.


Adjustments to your Handicap Index

We will no longer have a “ratcheting system” of handicap adjustment. Currently, a good score results in a much bigger handicap adjustment than having a poor score. A spell of poor form is rewarded by multiple 0.1 increases in handicap. Under the WHS your Handicap Index is likely to vary a lot more over the short term, the advantage being that it will better reflect your current form.

Your Handicap Index will be calculatd as the average of your best 8 out of the last 20 "Acceptable Scores" (see below). It is recalculated (just after midnight) whenever a new score is returned.

The upward movement of your Handicap Index within a defined period of time is however CAPPED, to limit the rate of increase during a period of particularly poor form.

For handicap purposes, a big score at any hole will still be reduced to a net double bogey.

There may also be exceptional score adjustments after a very low score is returned.


"Acceptable Scores" for Handicap Purposes

There are two categories :

1. Competition Scores – scores in all singles competition rounds of Individual Strokeplay (Medal or Stableford) played over a qualifying measured course from a specific tee.

2. General Play Scores – scores in non-competition and social golf can be used but pre-registration with the Pro is required. As with Supplementary Scores currently, you must register your intention to submit a score for handicap purposes prior to commencement of the round.

Team and Matchplay scores are currently excluded in England.


Playing Handicap

We have covered Course Handicaps, and how they are calculated by first by multiplying your Handicap Index by the Slope Rating, and then dividing by 113.

You will then need to determine your Playing Handicap by altering your Course Handicap, dependent on the format of the competition. For example:

  • In 4 ball Matchplay the restriction is 90%
  • Individual Strokeplay (Medal and Stableford) the restriction is 95%.

So a bit of juggling is necessary when it comes to getting the right handicap for recording scores on your scorecard.


Playing Conditions Calculation

Adjustment for course conditions on the day is made automatically by the software. It looks at all the scores submitted on the course for that day and determines if the course or weather conditions on the day differed from “Normal”. This is similar to the current CSS adjustment. If there is a howling wind blowing, most scores will be lower than normal, and the software will detect this and make appropriate adjustments.

The adjustment will however be conservative in nature. In easy conditions it may adjust the gross score for the round by 1, or increase the gross by up to 3 in tough conditions.


Other changes that you will notice

No “Competition” handicap status, “C” status
No handicap categories, currently Categories 1 – 6
No Standard Scratch
No 0.1 handicap increases
