12.0. Monitoring the Operation of the Rating System
One of the functions of Congress is to establish the policies
under which FIDE titles and ratings are awarded. The function of the rating
system is to produce scientific measurement information of the best statistical
quality to enable Congress to award equal titles for equal proficiencies of
players. Thus the rating system must be properly scientifically maintained and
adjusted on both a short and long term basis.
The rating scale is arbitrary and open ended. Thus only
differences in ratings have any statistical significance in terms of
probability. Thus if the composition of the FIDE Rating pool were to change, the
rating scale could drift with respect to the true proficiency of the players. It
is a major objective to ensure the integrity of the system so that ratings of
the same value from year to year represent the same proficiency of play.
Part of the responsibilities of the Rating System Administrator
is to detect any drift in the rating scale.
