Dear James

You will be aware that from the 2nd of November 2020, the current handicapping system for golf in Ireland (CONGU) is being replaced by the World Handicap System (WHS).

This note is an attempt to explain, with the help of the diagram below, the main impacts of the WHS as it applies to each golfers handicap going forward. Further detailed information is available on the GolfNet website regarding the WHS. This can be found at

When members enter a competition all the necessary calculations will be done by the system and they will be made aware of their playing handicap at that point. The following is to make members aware of how the system works.

The Handicap Index:

The Handicap Index replaces your existing exact handicap but note that it is not the handicap you will have when playing in the competition. The index is an averaged calculation based on the best 8 qualifying rounds out of the last 20. Prior to the launch of the WHS, scores for each individual member have been provided to the GUI to allow the initial calculation of an individuals handicap index. Your index will be available on a new website, from the 2nd of November. This website will become the source of all handicap information pertaining to players from this date while CLUBV1 will be used now to manage competitions only.

It is worth noting that the handicap index is recalculated at the end of each day and not at the end of competition close. This index can be viewed, going forward, by registering on the new site, GolfIreland. ( This site will be available from the 2nd of November onwards.

Attached for information is the Handicap Index for all male members at Fortwilliam as calculated by the WHS from scores provided

Slope Rating.

The slope rating is the number which indicates the relative playing difficulty of a course for bogey golfers compared to scratch golfers and is calculated using a combination of course and bogey rating. Again more detail on this can be located at
It is worth noting that the slope rating will vary depending on the markers being used, white, green or red.

Marker Slope Rating
White 114
Green 112
Red 129

Handicap Allowance

The handicap allowance is a further adjustment to the Handicap Index as you can see from the diagram and is based around the format of play. By way of example:

Format of Play Handicap Adjsutment
Individual Stroke Play 95%
Individual Stableford 95%
Fourball Stroke Play 85%
Fourball Stableford 85%
Individual matchplay 100%
Foursomes 50% of combined
Greensomes 60% of lowest h/c

Again further details on allowances can be located at
