The USGA will be migrating all GHIN Services into a modernized club & golfer administration platform alongside the World Handicap System launch beginning January 2020.
Through December the MGA will offer training materials and webinars to help clubs and golfers get acclimated with all the new GHIN golfer products. On January 1, 2020 the World Handicap System will launch with a new set of Rules of Handicapping. Although the Rules will be in effect as of the 1st, the underlying technology to support these changes will have a maintenance period of January 1-5 to enable the creation of a centralized computation database. Golfers with a Handicap Index today will have a new one calculated under WHS on January 6, 2020.
