Same Nine Played Twice

For 9-hole courses, the USGA recommends the AGA provide an 18-hole Course Rating and Slope Rating to accommodate players who play the 9 holes twice. Similarly, on an 18-hole course, if the same 9 holes are frequently played back-to-back, then the club should contact their AGA to publish an appropriate 18-hole Course Rating and Slope Rating.

If one nine is closed for maintenance, depending on the length of time the 9 holes are to be closed, the club should contact their AGA to publish an appropriate temporary 18-hole Course Rating and Slope Rating based on playing the same 9 holes twice as well as unpublish the previous Ratings. When the 9 holes reopen, the AGA may re-publish/publish new Ratings for the 18 holes and unpublish the temporary Ratings if playing the same 9 holes twice is no longer being done.

Note: If the AGA has not issued an 18-hole Course Rating and Slope Rating, then the following score posting guidance should be used.

If the same nine is played back-to-back on a course for other/infrequent reasons, it is acceptable to post two separate 9-hole scores resulting in two 18-hole Score Differentials. It is also acceptable to use manual entry, as long as the course played is first selected within the score posting product. As an example, if the Front 9 with a Course Rating and Slope Rating of 35.1/124 is played twice, then Ratings of 70.2/124 may be used to post an 18-hole score.
