RATINGS
Player ratings determine which bracket players who are over 18 years old play in for NTRP tournaments. USTA uses the National Tennis Rating Program (NTRP) to group players of similar ability. Players earn a rating based on how they fare against players with their rating. A player rating can go up or down at the end of each calendar year depending on how they do in their matches. If players do not have an NTRP rating when they register for a tournament, they will be asked to self-rate based on NTRP characteristics.
