2024 WORLD HANDICAP SYSTEM (WHS) CHANGES

 

  1. A lower minimum length for a golf course to obtain a Course Rating and Slope Rating. 

  • In 2023, an 18-hole course had to be at least 3,000 yards to receive a Course Rating and Slope Rating (or 1,500 yards for 9 holes).

 

  • With the 2024 WHS Revision: the yardage requirements have been cut in half, to 1,500 and 750 yards, respectively. This is good news for golfers who regularly play par-3 and shorter-length courses and have wanted those scores to count toward their Handicap Index.

 

  1. A new treatment of 9-holes scores

  • In 2023 and previous years, 9-hole scores were combined in the order posted to create an 18-hole Score Differential. This meant that a 9-hole score could have been combined with another 9-hole score from days, weeks, or even months before – which at times lead to volatile results.

 

  • With the 2024 WHS Revision: when a player posts a 9-hole score, it is combined with their expected Score Differential over 9 holes to create an 18-hole Score Differential for immediate use – with expected score based on the player’s Handicap Index at the time the round is played, as well as a course of standard difficulty.

 

How does the new formula work? Using the data gathered from previous year's posted scores, a model scoring formula for every handicap index for males and females has been developed. The appropriate one will be applied to your index and create an ‘expected score’ on any remaining holes you had for handicap purposes, taking the place of applying a score of net par for any missing holes. The new formula is built to account for a standard golf course, so the calculations are no longer course dependent compared to the math applied in the past.

 

Additionally, golfers who mostly play nine-hole rounds will have their handicap index updated in the same timely manner as those posting 18-hole rounds. Nightly calculations will be run for everybody in the WHS. Any lingering nine-hole scores will be recalculated under the new system in mid-January and any short-course score posted in the new year will show up around that time as well.

 

  1. An updated approach for holes not played

  • Prior to 2023, when a hole was not played (due to darkness, for example), the score recorded was a net par.

 

  • With the 2024 WHS Revision: when 10-17 holes are played, an 18-hole Score Differential is determined by adding the player’s Score Differential from the holes played to an expected Score Differential for the number of holes not played. Since a player’s expected score is not specific to a course or reliant upon the course’s stroke index allocation (as net par was previously), this will lead to more consistency.
