You will need a minimum of 1 woman playing in a women's division and a minimum of 3 players who are ratings propagators playing on the same course layout during each round. Propagators are PDGA Members rated 800+ with a minimum of 8 officially rated rounds. Ratings propagators are required to calculate the ratings for the 2 rounds included in the WGE.
You can tell which players in your tournament are ratings propagator by checking to see if their player rating is bold on your individual tournament results page. In the example below, only Mark is a ratings propagator so his player rating is in bold. William and Thomas are not propagators because they do not have a minimum of 8 officially rated rounds. Rudolph isn't current so he cannot be counted on as a ratings propagator.
