6.1b For a 9-hole Round

A 9-hole Course Handicap is calculated as follows:

Course Handicap = (Handicap Index ÷ 2(rounded to the nearest tenth)) x (9-hole Slope Rating ÷ 113) + (9-hole Course Rating – 9-hole par)

Rounding to the nearest whole number is the final step of the calculation.

(See Appendix E: Stroke Index Allocation for guidance on stroke index allocation for 9-hole rounds.)

Rule 6.1b Clarifications:

6.1b/1 – Use of 9-Hole Course and Slope Ratings in the Calculation of a 9-hole Course Handicap

When an Authorized Association issues Course Ratings and Slope Ratings to golf clubs, the 18-hole ratings should also be presented with front nine and back nine Course Ratings and Slope Ratings. For example:

 

 

White Tees (Men)

White Tees (Women)

Course Rating

Course Rating

Slope Rating

18-Holes

73.1

75.5

Holes 1-9

36.1

37.3

Holes 10-18

The calculation of a 9-hole Course Handicap must use the correct Course Rating andSlope Rating for the 9-hole golf course being played.

Note: The calculated 18-hole and 9-hole Course Handicap is rounded to the nearest whole number, with .5 rounded upwards, for the purpose of:

  • Applying adjustments for maximum hole score (see Rule 3.1 Maximum Hole Score for Handicap Purposes) and when a hole is not played (see Rule 3.2 When a Hole is Not Played).
  • Where applicable, calculating a Score Differential.

Otherwise, the full calculated value is retained and rounding occurs only after the Playing Handicap calculation.
