The USGA & The R&A announced updates to the World Handicap System™, effective January 2024.
Introduced in January 2020, the World Handicap System (WHS) was based
upon three key principles: be inclusive, provide a consistent measure
of ability, and remain modern. Four years later, with the first revision
to the WHS set for this January, those same principles apply to the
main changes going into effect, namely:
1) A lower minimum length for a golf course to obtain a Course Rating™ and Slope Rating™
Under the current system, an 18-hole course must be at least 3,000
yards to receive a Course Rating and Slope Rating (or 1,500 yards for 9
holes). Starting in 2024, the yardage requirements will be 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®.
2) A new treatment of 9-hole scores
Today, 9-hole scores are combined in the order posted to create an
18-hole Score Differential™. This means that a 9-hole score shot today
could be combined with a 9-hole score from days, weeks, or even months
before – which can lead to volatile results.
Beginning in 2024, when a player posts a 9-hole score, it will be
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.
3) An updated approach for holes not played
At present when a hole isn’t played (due to darkness, for example),
the score recorded is a net par. When the 2024 revision goes into
effect, when 10-17 holes are played, an 18-hole Score Differential will
be 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 is today),
this will lead to more consistency.
