I just thought that I should post a message about the ITF's International Tennis Number. This is a global Ratings Scheme that was launched by the ITF in January 2003.
The goal of this scheme is to enable all players worldwide to know where they rate to players globally.
A website has been developed that details how players from different countries can do an objective On Court Assessment that determines their Official ITN Rating.
Please go to www.oncourtassessment.com
and have a look as more and more countries are starting to adopt this system as their national rating system.
