Rules of Handicapping FAQs

9-Hole Scores

Q. How did the treatment of 9-hole scores change under the World Handicap System™ in 2024?

A. Beginning in January 2024, when a player posts a 9-hole score, the WHS™ will automatically calculate an 18-hole Score Differential™ for the round, based on the player’s 9-hole Score Differential and expected Score Differential based on their current Handicap Index®, allowing the 9-hole round to be considered in the player’s Handicap Index calculation right away.

As part of this change, golfers are required to play and post all 9 holes with a valid 9-hole Course Rating™ and Slope Rating™. Click here to watch a video about the treatment of 9-hole scores.
