WHAT IS UTR (Universal Tennis Rating)?

  • UTR® to provide is a universal scale for tennis players to self-assess. This is the first time our sport has had one common denominator; whereby a local player starting to engage and love the sport can compare themselves to the top juniors, to the best men’s and women’s open players locally, to each and every college player and program around the country, to pro circuit players, and also compare themselves to the very top pro tennis players like Federer, Nadal, Williams, and Sharapova.
  • UTR is a very straightforward rating system that college coaches generally put a lot of stock in for scouting and recruiting.  
  • UTR is not based on age or gender in any way, it is strictly a measure of level of play.
