The World Handicap System (WHS) was launched in January 2020 to replace the six different systems that were previously in use around the world.

​

The Oman Golf Association moved from the USGA Handicap System to WHS in May 2020 and in doing so also became part of the USGA's Golf Handicap Information Network (GHIN). GHIN is one of the largest handicap management tools in the world serving more that 2.3 million golfers. 

​

Developed by The R&A and USGA in close coordination with existing handicapping authorities, the WHS provides golfers with a more inclusive handicapping system with a consistent measure of playing ability and handicaps calculated in the same way wherever they are in the world.
