Tennis Levels Explained: NTRP, ITN, and Aussie Ratings

"What level are you?" is the most awkward question in adult tennis. The honest answer is "it depends who you are asking", because there are at least four different rating systems in use in Australia and most people use different ones in different contexts. This post explains each system, who uses it, and how to give an answer that is both honest and useful.

The four rating systems you will hear about

NTRP: the American National Tennis Rating Program, used widely in social and league contexts globally.
ITN: the International Tennis Number, used by the ITF and worldwide.
UTR: Universal Tennis Rating, the algorithm-driven one used in junior tennis and high-level competition.
AMT / Tennis Australia ranking: the formal Australian competitive rating used in tournament play.

On top of those, almost every Australian club uses its own informal "grade" (A, B, C, social, beginner) that has nothing to do with any of the above. It is the system most regular players actually use day to day.

NTRP, 1.0 to 7.0

NTRP is the rating system most social tennis platforms in Australia use as a baseline because it is well-known and simple. The scale runs from 1.0 (never touched a racket) to 7.0 (world top 50). Most recreational adults sit between 2.5 and 4.0.

The honest plain-English version:

1.0 to 1.5. Brand new. Still working out which way to hold the racket.
2.0. Has hit before. Can keep a rally going for a few shots if everything lines up.
2.5. Comfortable rallying from the baseline. Serves go in most of the time. Often loses on unforced errors.
3.0. Plays a full match without too much drama. Has a recognisable forehand and backhand. Volleys are sketchy.
3.5. The default level of an active adult Aussie social player. Solid groundstrokes, reasonable second serve, knows where to be on the doubles court.
4.0. Plays club competition successfully. Has tactics. Can adjust mid-match. Most pennant B-graders sit here.
4.5. Strong club player. Probably plays A-grade pennant. Coaches juniors on the side.
5.0+. State-level juniors, ex-tour, college-level returners, the people who quietly destroy you at the local court.

Self-rating is notoriously generous. The rule of thumb is to subtract 0.5 from whatever you first guessed yourself. If you are not sure between 3.0 and 3.5, say 3.0 to the person you are about to meet for a first hit. It is much better to overdeliver than to be steamrolled or to steamroll someone.

ITN, 1 to 10

The ITF's International Tennis Number runs from 1 (top tour pro) to 10 (absolute beginner). It is the inverse direction of NTRP, which causes endless confusion. ITN 5 is roughly NTRP 4.0. ITN 7 is roughly NTRP 3.0.

You will see ITN mostly on international platforms and in coaching contexts. It is less common day to day in Australian social play.

UTR, 1.0 to 16.5

Universal Tennis Rating is an algorithm: it takes match results, weighs them by opponent strength, and produces a single number for every registered player. The pro tour uses it. Junior tennis pathways use it. American college recruiting uses it.

For social play in Australia, UTR is overkill. You only have a UTR if you have played enough rated matches for the algorithm to compute one. If someone asks for your UTR at a social hit, they are probably a serious junior or a parent.

Tennis Australia AMT ranking

The Australian Match Tennis system is Tennis Australia's formal ranking for tournament players. It tracks points earned at AMT-sanctioned events. Only matters if you are playing tournaments. Useful to know exists so you can recognise when someone is talking about it.

The informal club grade

The system most Aussie social players actually use:

Beginner: less than a year of play, still learning fundamentals.
Improver / social: comfortable rallying, plays for fun, no league.
C grade: lower-tier pennant, learning to play competitive sets.
B grade: solid pennant player, full match repertoire, occasional tournament.
A grade: top of the club ladder. Often ex-juniors or coaches.

Most clubs draw their own line between these. A B-grader at one club might be an A-grader at another. Geography matters: A grade in regional Tasmania is not A grade in inner-west Sydney.

How to honestly self-rate

A simple way to land in roughly the right NTRP bucket without overrating:

How many forehands in a row can you hit cross-court between the service line and baseline at medium pace? Under 10 means 2.5 or below. 10 to 20 means 3.0. 20-plus, comfortably, means 3.5.
What percentage of your second serves go in safely? Under 60% means 2.5. 60 to 80% means 3.0 to 3.5. 80%-plus means 4.0+.
Can you hit a volley back over the net 8 out of 10 times when the ball is fed nicely? No means 2.5 to 3.0. Yes means 3.5+.
Have you ever played a competitive set against someone you knew was better than you, and won at least three games? No means under 3.5. Yes means 3.5+.

Tally honestly. Most adult players who have been hitting once a week for a year or two land at 3.0 to 3.5. That is not a low score: it is the modal level for an active recreational Australian player.

What to actually say to a new hit partner

When someone asks your level before a first hit, the most useful answer combines a number and a context:

"I am probably a high 3.0 on NTRP. I play once a week, mostly social, comfortable rallying but my serve is patchy."

That is more useful than "3.5" alone, because it tells the other person what to expect and what to bring. They can play down or up, pick the right warm-up routine, and avoid the awkward first 15 minutes of figuring each other out.

How RallyHub handles ratings

On RallyHub we use NTRP as the default rating scale because it is the most widely understood, with a short plain-English description on every player profile so the number is not the whole story. We have considered switching to UTR or building our own algorithm-driven score from match history, and we may at some point. For now, the rule we push is the same one in this post: when in doubt, rate yourself half a point lower than you want to.
