The Low Handicap Index™ is the lowest Handicap Index® for the player during the 365-day period (one year) preceding the day on which the most recent score on their scoring record was played. It is not calculated; it is derived from each of the issued Handicap Index values that a golfer has on record during the eligible time period. A player does not have a Low Handicap Index until they have 20 scores in their record.
