How to Keep Score at a Junior Tennis Match: A Guide for Parents and Coaches

Tennis rules · Junior tournaments · Updated 2026-09-08

At most levels of junior tennis there is no chair umpire. Two players walk on with a can of balls, spin a racquet, and from that moment they are responsible for the lines, the score and the pace of play. A roving official covers several courts at once and steps in for disputes, timing and conduct, but nobody is writing the score down for them. The players own it.

If you are a parent or a coach in the stands, that can feel uncomfortable in a tight third set. This guide covers who is responsible for the score, how it should be called out loud, what the players do when their numbers do not match, and what a spectator may and may not do. It also covers keeping your own quiet record, which is the most useful thing you can do from the sideline. If you are still learning the scoring itself, start with how tennis scoring works.

The players keep the score, and the server announces it

In a self-officiated match both players are jointly responsible for the score, and by convention the server announces it: the point score before every point, and the game score before every game. It is not a formality. It is the mechanism that keeps two people in agreement over two hours, and it heads off most of the score disputes you will ever watch.

Announcing means loud enough that the opponent hears it from the other baseline, before the toss. The receiver's job is to listen and to say something immediately if a number is wrong. The moment to correct a score is before the next point is played; three points later, far more of the match has to be unwound.

What gets called, and when

Server's total first is the convention at every level, and it removes ambiguity: thirty fifteen and fifteen thirty are different scores, and who is speaking tells you which. At three points all the call is deuce, then advantage to whoever leads, and that can swing back and forth many times, which is exactly where two honest players quietly diverge. See what is deuce in tennis for that, and tennis tiebreak rules for how the count and the serve rotate once a set reaches 6-6.

Where the score actually drifts

Disputes almost never begin at thirty fifteen in the second game. They begin at a few predictable moments, and if you know them you can see trouble arriving before the players do.

• The changeover. Players sit, drink, replay the last game in their heads, then stand up carrying two different game totals.
• A long deuce game, where one player has counted a swing of advantage that the other has not.
• A let, or an unintentional hindrance. The point is replayed, and one player scores it anyway.
• The end of a set. One player has it finished at 7-5, the other has 6-5 and is waiting to serve again.
• The switch into a tiebreak, where the point count restarts from zero and the serve rotation changes.
• A first serve that one player counted as a fault and the other has forgotten.

The fix for nearly all of it costs nothing: both players say the score out loud at the changeover, before either one sits down. Games, sets, and who serves next. Two seconds there saves the argument that otherwise arrives at 5-4 in the third.

When the two players disagree

It happens in every tournament, on every court, and there is a calm standard procedure that junior players are taught. The principle is simple: keep whatever both players agree on, and replay only what is genuinely in dispute. Nobody gets to set the score by being louder or more certain.

1. Stop before the next point: As soon as one player hears a score that does not match, play pauses. Once another point has been played on a disputed score, the untangling gets harder.
2. Go back to the last score both agree on: Work backwards together to a point score both remember the same way. Everything up to it stands, and the disputed points are replayed from there with the correct server and the correct side of the court.
3. Apply the same idea to games: If it is the game count that slipped, keep every game both players agree was won and replay only the one in dispute. If neither can reconstruct the set, resume from a score both are willing to accept rather than insisting on being right.
4. Let the agreed score decide serve and ends: Who serves and which end each player stands on follow from the score. If they do not line up, the score is still wrong somewhere, and the mismatch tells you roughly where.
5. Ask for the roving official rather than argue: Either player may stop and call for the official, and asking is not an accusation about the opponent. The official helps reconstruct the score or decides how play restarts, and that ruling stands.

What a spectator may do, and must not do

Watching is welcome. Officiating from the stands is not. Line calls and the score belong to the two people on court, and coaching is allowed only where the event's own rules allow it. Some junior events permit coaching at changeovers or set breaks and many permit none at all, so read the tournament information rather than assuming.

The first row is the hardest. You will see a ball that was clearly in get called out, and there is nothing to be done from where you sit. Note it, and if a pattern builds across a set, ask the official to come and watch the court. Officials would far rather stand quietly on a court for three games than sort out an argument afterwards.

Keep your own record, quietly

The most valuable thing a spectator can do is keep an accurate private record: not to enforce it, and not to wave it at anybody, but so that if the players get stuck you can give the official a clear account of who served which game and how each one finished. An official arriving at game eleven has no information at all, and you have all of it. Fill each game in as it ends, because your memory drifts in the same places theirs does.

The end of the court is the quiet cross-check that catches everything else. Players change ends after the first game of a set and then after every subsequent odd-numbered game, and at the end of a set only when that set's total games are odd. The full pattern is in when do you change ends in tennis. If your card says they should have swapped after game five and they have not, one of the two records is wrong, and you have found out at 3-2 rather than at 5-4.

The record keeps itself. Tennis Score Keeper₊ is a rules engine rather than a tally counter: it tracks games, sets, who serves, which side of the court, deuce and advantage, tiebreak rotation and the changeover count, with unlimited undo back to the first point. It is coming soon for iPhone and Apple Watch, so a parent in the stands can follow a whole match by tapping only two buttons. Learn more about Tennis Score Keeper₊.

Format, warm-up and defaults, in general terms

Junior events run on a schedule and often use shortened formats to keep courts moving. Before the first point, find out from the desk or the draw what is being played, because a set that ends at four games, or a third set replaced by a ten-point match tiebreak, changes the shape of what you are watching. The options are compared in tennis match formats explained.

• Warm-up is short, taken together on court, and includes a few practice serves. The length is set by the event.
• Late arrival follows the event's own published policy, typically a grace period with increasing penalties and a default past a longer limit. Check the tournament rather than assuming a number.
• Players are responsible for being courtside when the match is called, not for being tracked down.
• Balls, and who supplies them, are set by the event, as are rules on phones, headphones and video on court.
• A player may retire, and only an official may default a player, so neither is something the two players settle between themselves.

Etiquette from the stands

• Applaud good play from both players, and never a double fault or an unforced error.
• Keep your reactions small. A junior reads a parent's face from the far baseline, and so does the opponent.
• Stand up, move and leave between points or at changeovers, never during a point.
• Do not signal, nod or mouth anything at your player where coaching is not permitted. It counts, and everybody can see it.
• Take anything you need to raise to the official at a changeover, and speak to the official rather than to the court.
• Say nothing about line calls, before, during or after.

A short courtside routine

1. Confirm the format before the first point: Sets, games per set, no-ad or advantage, and what replaces a third set. Write it at the top of your card so you are never guessing at 4-4.
2. Note who serves first and who chose ends: The spin decides it, and the whole serve and end pattern for the set follows from that one fact.
3. Write each game down as it finishes: Winner, server, running total, and a mark if it went to deuce. It takes a second between games.
4. Check the ends at every changeover: If the players are on the ends your card predicts, both records agree and you can relax until the next one.
5. Stay silent while the match is live: No calls, no coaching, no score corrections across a fence. If something needs an official, go and get one.

Self-officiated tennis works better than it sounds like it should, because it rests on two people saying a number out loud a few hundred times in an afternoon. Your job in the stands is to make that easier, not to supervise it. Keep your record, keep quiet, and let the players run their match.

Frequently asked questions

Who keeps score in a junior tennis match?

The two players do. In self-officiated junior matches there is no chair umpire, so the players call their own lines and keep the score jointly, and the server announces it before every point and every game. A roving official supervises several courts and steps in for disputes, timing and conduct rather than calling every point.

What happens if two players disagree on the score?

They go back to the last score both players agree on and replay from there. Points and games that both remember the same way stand, and only the disputed part is replayed, with the correct server and the correct sides of the court. If they cannot reach an agreed score, either player can stop and ask the roving official, whose decision settles it.

Can a parent call the score or make line calls from the stands?

No. Line calls and the score belong to the players on court, and a call from a spectator has no standing. If you believe the score is being miscalled repeatedly, note the specific games and raise it with the official or the tournament desk rather than saying anything to the court.

How often should the score be called out loud?

Before every point and before every game, with the server's own total first. Both players should also say the full score at each changeover before sitting down. Most score disputes trace back to players who stopped announcing once the match got tight.

What does a roving official do at a junior tournament?

A roving official supervises several courts at once and handles disputes, time between points, conduct and defaults rather than calling lines on every point. Either player may stop play and ask for one, and asking is normal rather than an accusation. The official's decision on what happened on court settles it, and a question about how a rule applies can be taken to the tournament referee.

What should I write down when I follow my child's match?

Record each game as it finishes: the game number in the set, who won it, who served, which end the players are on, and a mark if the game reached deuce. Add the set score and, for a tiebreak, the points. That gives an official something concrete to work from if the players get stuck.

Do juniors change ends at the same times as the pros?

Yes. Players change ends after the first game of each set, then after every subsequent odd-numbered game, and at the end of a set only when that set's total number of games is odd. The changeover is also the most common place for the game count to drift, which is why both players should say the score out loud there.
