I don't know the Course Rating™ and Slope Rating™ for the tees I played; how can I post the score?

Through the USGA GHIN Mobile App or GHIN.com, you should be able to search for the golf course you played and find the set of tees played and appropriate ratings for your gender. Alternatively, you can search the Course Rating and Slope Rating Database™ found here. If the Rating information cannot be found in your posting application or on the database, you should contact your club who can consult with Washington Golf to see if valid Ratings are available.
