  Ratings lists show a player's name, tournament rating, overall ranking and membership status, and as of January 2009 the number of rated games they have played in their career.

  • Tournament Directors must be careful to use player names exactly as they appear in the ratings list, to be sure that the right player is credited for tournament results.
  • Tournament ratings are calculated at the end of each NSA-sanctioned tournament and posted in cross-table form at this web site. A full list is compiled each month and is available electronically here and in hardcopy form.
  • Overall rankings are shown only in the online list, and include only those players who have played in at least 28 rounds of fully rated tournaments in the last 24 calendar months. (Until the end of May 2007, players were considered active if they had played at least one round in the past 12 calendar months.)
  • The membership status of players in good standing is shown as the issue number of the last newsletter which is due to be sent to them. Lapsed members are marked 'EXP'. Some players are marked '***'; this either means that they have never been members, or that their ratings list name does not exactly match their subscription name. For instance, John Chew might be playing as John Chew but receiving a subscription as John J. Chew. In this case, we would appreciate being informed of which form of the name is the preferred one. Please note however that the overall ratings list is updated monthly, so changes submitted will not appear online until the beginning of the following month.
  • The number of rated games a player has played affects their rating changes, in that player ratings change by 50% more until a player has played 50 games.
• See also the tournament results on which these ratings are based.

* The NSA is indebted to JC Green, who recovered and supplied a copy of the December 1999 ratings list after it had accidentally been deleted.
