Juniors (18 and under) 

Most junior players will experience a decrease in their rating because of the changes. This is addressing some junior players starting too high on the WTN scale and seeing their initial WTN decrease when they play their first matches. These changes will be applied retrospectively since the launch of the WTN and all players will decrease within their cohort. The player ratings are now more of an accurate reflection of age, with a general incremental decrease in initial rating expected from aged 10 upwards.   

Adults (18-40 years old) 

Most adult players should expect only minor changes to their World Tennis Number. Players playing many matches against Junior players will likely decrease towards 40.  

Masters (40 years old +) 

Masters players’ will mostly see relatively smaller changes to their numbers in either direction of the scale relating to how their match results are weighted. Some will experience larger differences than others due to the profile of opponents they have played. 

Players with a verified WTN will see less change than those who don’t have a verified WTN (i.e. they are less frequent competitors recording fewer match results).
