Ratings

Since 2009-07-01, NASPA has assigned ratings to players based on their performance at NASPA-sanctioned tournaments. On that date, NASPA inherited the NSA’s rating system, copying all current ratings to the new system.

The rating system is designed by the Ratings and Recognition Committee, implemented through a web application being developed by Web Committee, operated by the Tournament Committee.

NASPA tournaments are either fully rated or, in the case of Local Club Tournaments, 1/3-rated; the latter meaning that normally applied changes are divided by three. NASPA tournaments played with the SOWPODS lexicon may also count toward WESPA ratings.

The rating system overview describes how the rating system works at a very high (and not too technical) level.

The submitting tournament results article describes how to submit tournament results into the rating system.

Current ratings

You can find current rating information in the following places on this web site:

• full rating list as a 300K text file
• search by name
• search by rating or rank

You may also be interested in the tournament results (cross-tables) that contributed to these ratings.

Monthly ratings

For the sake of historical continuity dating back to a time when ratings were not available online and printing and shipping costs were significant, a monthly rating list is published near the beginning of each month. This list includes the results of all events that have been received as of when the list is finalized. When there are events which take place near the end of a month, and directors are late in submitting rating data, those events may count toward the following month’s rating list. Directors are encouraged to use the most recent available ratings for placing players in their tournaments.

How to read the ratings

The listings are simple text files with columns delimited by tabs. Each row contains the data for one rated player.

List of columns starting January 2009:

1. Player’s name (in all caps, starting with the last name)
2. Rating
3. Ranking (among all active players in the system)
4. NASPA membership expiration date in ISO8601 format (for the monthly listings for the first half of 2009, this value reflects the membership status as of the beginning of July 2009).
5. Cumulative number of rated games in the system (including games rated by the NSA).

List of columns for 2008 and before:

1. Player’s name (in all caps, starting with the last name)
2. Rating
3. Ranking (among all active players in the system)
4. NSA membership expiration (the number of the last issue of Scrabble News paid; EXP means expired, *** means non-member or non-matching name).

For rankings, a player is considerd active if he or she has played at least 28 rated games in the preceding 28 calendar months (until May 2007, the limit was 1 game in 12 months).

State and provincial rankings

The list of state and provincial rankings lists all active NASPA members according to their U.S. state or district, Canadian province or country. This list is updated with every change to the rating system, and archived at the end of each rating month. Archived lists prior to 2009–08 were made available by the NSA.
