Timeline / Implementation

The World Handicap System will launch on January 1, 2020. The final revision under the USGA Handicap System will be on December 15, 2019. At this time, please print all necessary reports that might be needed for future reference as these reports will no longer be available after December 31. There will be no revision on January 1, 2020, while GHIN goes offline for maintenance while the new platform is put into production for a launch on January 6 with the first revision of the World Handicap System.

Information and resources on the new GHIN platform can be found under “Launch 2020” on WPGA Product Support (Currently in maintenance - To be published on 12/31/19).

In January a package of information will be sent to each Member Club that will include a copy of the Rules of Handicapping and new Stroke Index Allocation tables for each rated set of tees to go along with the implementation of the World Handicap System.

As part of the rollout, the WPGA will be conducting five seminars throughout our jurisdiction to educate Handicap Committee Chairs, club staff, and the general public. Included in the Rules of Handicapping is a Club Authorization requirement that requires a member of the club, i.e. Handicap Committee Chair, to attend a workshop on the World Handicap System and pass a quiz showing proficiency.

Please contact the WPGA at any time with any questions or if you need assistance. We look forward to seeing you soon.
