GHIN vs GN21 thru the LPGA Amateur Golf Assoc.

Register for GHIN thru CGA 



Experienced Golfers: Golf allows friendly and serious competition between players of differing abilities.  A handicap enables golfers to compete fairly - each player with the opportunity to succeed.  Since many LPGA Amateur golf events include some type of competition,  members with USGA handicaps ensure that they compete fairly with the other LPGA Amateur members.  In addition, a member must have a current handicap index to compete in the LPGA Amateur Champions Cup series, and the LPGA Amateur Championship Series which begins with the Chapter Championship, and other Chapter golf events.  A player without an index may always participate in the fun division.


Newer Golfers:  In addition to the reasons listed above, a handicap can gives tangible evidence of improvement. Many of our new players also suggest that having a handicap makes one feel like a real golfer.  For most competitions, we allow higher handicap players to participate, but they must play at a maximum of 40.4.  The exceptions are the Chapter Championship, Stroke Play division and the Championship Cup Match Play division.  A player must be 40.4 or below to compete.  Chapter Championship Scramble Teams may include players with an index of 40.4 or higher.  The same requirement of 40.4 maximum applies.

What do I need to establish a handicap?

To set up a handicap, please collect information on five or more 18 hole rounds you've played.  Some may be 9 hole rounds as long as they equal five 18 hole rounds.  If you are using the LPGA Women Who Play GN 21 system (formerly Golf Life Management System), you will establish service and post scores at the national website.  Following member log in, choose Handicap.  For CGA GHIN service we have a link to sign up through LPGA Women Who Play as a member with CGA Then, establish your handicap. Handicaps are adjusted on the first and 15th of every month.  

Which service should I choose?    


LPGA Women Who Play Headquarters established the GN21 service in 2004.  It is included in your dues and is maintained online. This is a valid USGA Handicap and can be used for all events except those specifically sponsored by the Colorado Golf Association, "CGA" such as the Team Competition and other Statewide CGA events. Please consider the features on the table below when deciding whether to use the CGA system or use the LPGA Amateur GN21 system.  These systems are independent of one another and because of this, it is highly recommended that you utilize only ONE system.

Excerpts from the CGA website on handicaps:

The purpose of the USGA Handicap System is to make the game of golf enjoyable by enabling golfers of differing abilities to compete on an equitable basis. A golfer begins with a USGA Handicap Index and converts that to a Course Handicap based upon the Slope Rating of the golf course being played.

The handicap calculated reflects a golfer's "potential" ability to play the game. With this in mind, the system disregards unusually high holes played or rounds posted. One of the basic premises of the USGA system is that golfers will try to make the best score they can on each and every round they play. They will also post every acceptable round for peer review.
