Handicap in WHS

The Handicap Index in World Handicap System (WHS) is the designation of “the measure of a player’s demonstrated ability on a course of standard relative playing difficulty (that is, a course with a Slope Rating of 113)”. It is expressed as a number taken to one decimal place, to a maximum value of 54,0.

The player must have only one Handicap Index and use it around the world at whatever course he (or she) is playing.

  • Handicap Index is the average value of the lowest 8 of the most recent 20 Score Differentials in the player’s scoring record.
  • Score Differential is the numerical value attributed to a score (Adjusted Gross Score) achieved during a round of golf. It is calculated by de-sloping the score back to a course of standard difficulty.
  • Adjusted Gross Score is the number of strokes scored on all holes, adjusted for net double bogey on a holes, where number of strokes exceeds net double bogey (hole par + 2 + handicap strokes received on this hole).
  • Number of handicap strokes is determined by Course Handicap. It is the number of strokes a player receives for a specific set of tees at the course being played. A player is entitled to deduct these strokes from his gross score.
  • Course Handicap is a Handicap Index adjusted for the playing difficulty from a specific set of tees (calculated on the base of the Course Rating, Slope Rating and par).
  • Scoring Record is a register of a player’s submitted scores.
