These Top 100 lists are updated every two months by the United States Chess Federation. Ages are as of the first day of the month in which the lists are first published. For example, ages for the December lists (published in November) are as of November 1.

Ratings shown are the official USCF ratings for the month indicated, which are generated early in the month before they become official. Only current USCF members with established ratings and ratings activity in the last year are shown. Please contact us if you have questions about these lists.
