USGA Handicap Formula™
Handicap differentials are computed by determining the difference between the adjusted gross score (after, applying ESC) and the USGA Course Rating, multiplying the difference by 113, dividing the resulting figure by the USGA Slope rating and rounding off to the nearest tenth.
|Example #1:||Adjusted gross score||95|
|(Slope=125)||USGA Course Rating||-71.5|
|Handicap Differential||(23.5*113)/125 = 21.2|
|Example #2:||Adjusted gross score||95|
|(Slope=100)||USGA Course Rating||-71.5|
|Handicap Differential||(23.5*113)/100 = 26.6|
The 10 lowest differentials of the 20 most recent acceptable scores are selected and totaled. This figure is then multiplied by .096 and all numbers after the tenths digit are deleted (do not round off to the nearest tenth).
*10 lowest differentials
Total of 10 lowest handicap differentials = 154.8
Total multiplied by .096 = 14.861
Delete all numbers after the tenths digit = 14.8
USGA Handicap Index equals = 14.8
Fewer than 20 Scores Available
A USGA Handicap Index shall not be issued to a player with fewer than five scores. When at least 5 but fewer than 20 acceptable scores are available, the formula for determining a USGA Handicap Index is as follows:
Score Posting & Handicap FAQs
When should I post my scores?
Post your scores as soon as possible at the golf course terminal where you played. Any other method of posting (Posting via the Internet, posting the score at your course when you next play, etc.) should be secondary options of score posting not the first.
How do I post scores at a golf course other than my home course?
You would choose the Guest/IGN Score Posting Option, enter your GHIN number, select Post Score and then enter your round information to have your posted score transmitted to GHIN and then routed back to your club.
Can I post my score at a club that doesn't use GHIN as its handicap computational service?
Yes, you would choose the Guest Score Posting Option, choose Washington Golf from the list of participating golf associations and then enter your score information which will be routed back to your home club. Your score will be transmitted to GHIN through a service called the International Golf Network (IGN). WA Golf pays a yearly fee to the IGN so that our members can use this service when needed.
How many holes do I need to play to post an 18-hole score?
That an 18-hole score needs to be posted if you play 13 or more holes. If you play 7 to 12 holes you need to post a nine-hole score. Any hole not played should be recorded as par plus any handicap strokes you are entitled to for that hole. This score should be preceded by an “X”.
Do I have to use Equitable Stroke Control (ESC)?
For handicap purposes, all scores including tournament scores are subject to the use of ESC. This required procedure reduces high hole scores in order to make handicaps more representative of a player’s “potential” ability. There should be an ESC chart by all of the WA Golf Handicap System computers.
What should I do if my score gets posted twice or I post an incorrect score?
