National Tennis Rating Program (NTRP)
The NTRP rating system is used to match tennis players of comparable skill levels so they can get the most enjoyment out of matches, group lessons, leagues, and tournaments.
For most situations, you can rate yourself. Read the criteria below and imagine you are competing against a player of the same ability and gender as yourself. Once you identify a level that best describes your abilities, check that you meet most or all of the criteria of the skill levels lower than the one you have selected as your rating. If you have difficulty choosing between two levels, go with the higher rating. Results based on past participation in USTA sanctioned tournaments and leagues can also be used to determine your NTRP rating.
Remember, ratings are not permanent and can be adjusted based on your play and match results.
