Launched in January 2020, the World Handicap System (WHS) has been guided by three core principles: inclusivity, a consistent measure of ability, and modernity. As the system undergoes its first revision in January 2024, these principles remain central to key changes taking effect. Notably, the minimum length requirement for a golf course to receive a Course Rating™ and Slope Rating™ will be halved to 1,500 and 750 yards, respectively, a significant benefit for those playing shorter courses. Additionally, the treatment of 9-hole scores will be revamped, combining them with expected differentials for immediate use. The approach to unplayed holes will be updated, with an 18-hole Score Differential calculated by combining played and expected differentials. These changes aim to enhance consistency and accuracy in handicaps, catering to the diverse needs of golfers.
