Feedback has helped to shape the WHS, which has been developed by the USGA and The R&A with support from each handicapping authority as well as the Japan Golf Association and Golf Canada.

The World Handicap System launched its first revision in Canada January 17th, 2024

As part of an ongoing review of Rules and Handicapping™ and Course Rating System™ with a continued emphasis on accuracy, consistency and equity. The revisions will go into effect January 17, 2024.

Many countries have seen significant increases in the number of scores being submitted for handicapping purposes since the WHS was introduced, reflecting golf’s broadening appeal. More than 100 million scores have been posted each year, unifying millions of golfers through a standard measure of playing ability. The 2024 update leverages the performance data gathered from around the world, in addition to feedback received from many of the 125 countries now using the system.

Significant updates to the WHS include:

• Inclusion of Shorter-Length Golf Courses Within the Course Rating System: The overall length requirements for Course Rating in the WHS will be significantly reduced. A set of tees on an 18-hole course may be as short as 1,500 yards [1,370 metres] to be eligible for a Course Rating and Slope Rating^®, and a set of tees on a 9-hole course may be as short as 750 yards [685 metres]. This change is intended to expand the WHS to thousands of shorter length courses, including par-3 courses, and enable more golfers to obtain and use a Handicap Index.

• Use of an Expected Score for a Hole Not Played: Improvements have been made to the method used to handle holes not played, which will now be based on a player’s expected score rather than a score of net par. This new method will produce a 9-hole or 18-hole Score Differential that more accurately reflects a player’s ability. As golfers across the world are playing more 9-hole rounds, an expected score can also be used to convert a 9-hole round into an 18-hole Score Differential. For some countries, this means that 9-hole scores will be considered in the calculation of a player’s Handicap Index immediately after the day of play, rather than waiting to combine with another 9-hole score.

• Playing Conditions Calculation Adjustments Made More Frequent: The Playing Conditions Calculation (PCC) has been modified to increase the likelihood of an adjustment for abnormal playing conditions. National associations were given discretion, beginning in July 2022, to introduce this revision within their computation platforms, which will be complete by 1 April 2024.

• Enhanced Guidance on Conducting a Handicap Review: The role of the Handicap Committee is vital to the success of the WHS and the Rules recommend that a Handicap Review is conducted regularly, or at least once a year to ensure a Handicap Index^® remains reflective of a player’s ability. New reporting tools have been developed that national associations can incorporate into their handicapping software to assist Committees in conducting the review process effectively and consistently

Golf Canada is excited about the above changes, and is also proud to continue to offer the following features of the World Handicap System:

• Flexibility in formats of play, allowing both competitive and recreational rounds to count for handicap purposes and ensuring a golfer’s handicap is more reflective of demonstrated ability.
• A minimal number of scores needed to obtain a new handicap. The number of scores needed to establish a Handicap Index is 54 holes from any combination of 18-hole and 9-hole rounds.
• A consistent handicap that is portable from tee to tee, course to course and country to country through worldwide use of the World Handicap System.
• An average-based calculation of a handicap, taken from the best eight out of the last 20 Score Differentials and factoring in memory of previous demonstrated ability for better responsiveness and control.
• A calculation that considers the impact that playing conditions (including course set up and weather conditions) might have on a player’s performance each day
• Daily handicap revisions, taking account of the course and weather conditions calculation.
• A limit of Net Double Bogey on the maximum hole score (for handicapping purposes only). Net Double Bogey will replace the previous Equitable Stroke Control (ESC) procedure for determining the maximum hole score.
• A maximum Handicap Index of 54.0, regardless of gender, to encourage more golfers to measure and track their performance to increase their enjoyment of the game.
