Understanding the

NTRP Rating System

September 16, 2019

On September 12, 2019, the Senior Product Manager - Events and Ratings of the USTA, Heather Hawkes visited the Caribbean Puerto Rico district to present the talk “Understanding the NTRP. "


Heather, had the task of clarifying all kinds of doubts about the rating system for the players of the recreational leagues of the USTA.


 After the conference, Heather was able to answer questions in a Q&A in which league players of all categories, team captains, parents, volunteers and board directors participated.


It was a very good initiative for all those who wished to clarify their most frequent doubts such as: why did they raise me? How do the ratings work? How do they calculate the ratings? Among other questions.


What is NTRP?


Developed in 1978, the National Tennis Rating Program (NTRP) is a classification system that identifies and describes general characteristics of tennis-playing ability. ADVERTISEMENT The NTRP General Characteristics Guide outlines the abilities of each level from 1.5 (beginner) through 7.0 (touring pro). Generally, USTA League offers programs for the 2.5 through 5.0 levels.


How does the year-end NTRP calculation work?  (Also in Year-end)


Computerized ratings are affected by the score of a match as well as your partner’s and your opponent’s dynamic NTRP rating. Based on player dynamic ratings at the start of a match, the NTRP algorithm expects a particular outcome of a match. The actual outcome is then compared to the expected outcome and, as a result, a player’s dynamic rating adjusts up or down (or there is no change, if the outcome was as expected.) Computerized ratings are not directly affected by what position you played, your actual number of wins and losses, age, or team standing.
