AGA Rating System

   

If I am remembering this correctly, there is a distinction between AGA ranks (kyu, dan) and AGA ratings (-1.0, 3.5). I think an analogy would be between Elo ratings in chess and the various classes (Master, International Master, etc). So in the AGA system, the highest rank is 7-dan, but the ratings have no cap. This probably explains why Jie Li is listed as a 7-dan, since his actual rating could very well be 9.x. KGS uses a similar system -- players like toxxicu are 7-dan but several levels higher than other 7-dan players.

SAS: Some more (and more certain) information would be useful. The following is my understanding of the AGA system, but I don't live in America and would appreciate some confirmation for all of this.

The AGA rating page is here: [ext] http://www.usgo.org/ratings/default.asp


The above is essentially correct. The AGA does not (at present) set or define "ranks", only "ratings". However, it is common practice to convert a rating to a rank as outlined above. Players may not enter a tournament at a rating less than their current official rating. Unrated players, and players that believe they are stronger than their official ratings enter using their best estimate of their current strength, with approval/guidance from the TD.
