2024 World Handicap System™ Revisions Hub

The USGA and The R&A have jointly introduced several major changes to the World Handicap System™. The changes predominantly focus on making more rounds of golf count towards a Handicap Index®. The changes go into effect on January 16th, 2024, in regions where active score posting season extends year-round (note: active score posting season in Massachusetts runs from April 1st to November 14th).

As previously devised, 9-hole scores awaited a second 9-hole round to be paired with, however, with the new change, a second 9-hole round is not necessary–-an expected 18-hole score differential will be calculated based on the 9-hole score. Further, players can post rounds of 10-17 holes and the Handicap System will automatically generate an expected 18-hole score differential.

Additionally, the minimum total yardage for official courses has been significantly reduced (now 1,500 yards for 18 holes), meaning that official rounds can be conducted at par-3 courses and the like.
