2019 Rules of Golf - Effect on CONGU Handicapping.

There are several new Rules, that will impact on Handicapping including Local Rule E-5 (Alternative to Stroke and Distance for Lost Ball or Ball Out of Bounds), whereby this rule is only appropriate for general play. It is not allowed when scores are to be submitted for handicap adjustment (Qualifying Competitions and Supplementary Scores).
Please see CONGU’s Guide for Committees for where other Rules have an effect on Handicapping.

A modern handicap system for all golfers everywhere. 
The new World Handicap System (WHS) has been designed to encourage more golfers to obtain a handicap - enabling them to play with, or against, each other anywhere around the world.

The idea for a new, unified system was conceived by The R&A and the USGA and developed following an extensive review of existing systems administered by six handicapping authorities. Adaptable across golfing cultures, the proposed new system will provide players with a consistent measure of playing ability globally, helping to make the game of golf more enjoyable.
