Equitable Stroke Control (ESC) was a component of some golf handicapping systems that were in use prior to the implementation of the World Handicap System in 2020. It was used to adjust recorded scores in order to more accurately calculate a player's handicap. Its purpose was to avoid one or more very high scores on individual holes inflating the handicap calculation.
Equitable stroke control was a sliding scale system, based on the course (or playing) handicap of the golfer.
