The direct answer: junior tournaments don’t all use the scoring you see on TV, and the format changes with your kid’s age — 10s often play no-ad short sets to 4, 12s play fuller scoring, and some events use pro-sets or even timed matches when the facility needs courts back. None of it is random. Once you know the format table for your kid’s division, you’ll never be the parent asking the referee “wait, what are we playing?” five minutes before the match.
Why Formats Change by Age
The logic is simple: shorter attention spans, smaller bodies, and tighter schedules. A 10-year-old playing full best-of-3 with ad scoring could be out there for three hours — that’s not development, that’s attrition. So tournaments scale the scoring to the division:
- 10s (orange/green ball): usually short sets to 4 games, no-ad scoring, often with a 7-point tiebreak at 4-4. Matches wrap in 45–75 minutes.
- 12s: typically best-of-3 short sets or full sets depending on the tournament level; no-ad is common at lower levels, ad scoring appears as levels rise.
- 14s–18s: best-of-3 full sets with ad scoring at higher-level events; no-ad and short sets still appear at local and entry-level events.
- High school: varies by state — many play pro-sets (first to 8, win by 2) or best-of-3 with a 10-point match tiebreak in lieu of a third set.
Always check the tournament’s homepage before you go. The format is listed there, and it overrides every assumption.
The Formats, Translated
No-ad scoring. At deuce, the next point wins the game — the receiver chooses which side to receive on. It shortens matches and makes every deuce point electric. Kids either love the drama or melt under it; either way, practice it at home so the first no-ad deuce isn’t in a tournament.
Short sets (first to 4). Same as a regular set, just shorter. At 4-4 you play a tiebreak. The big strategic difference: there’s no time to “settle in.” Slow starters get punished — two loose service games and the set is basically gone.
Pro-sets (first to 8, win by 2). One long set instead of best-of-3. Common in high school and some adult/junior events. The danger: one bad 15-minute stretch can bury you with no second set to reset.
10-point match tiebreak in lieu of a third set. Split sets? Instead of a full third, you play a single tiebreak to 10 (win by 2). This is increasingly standard — it keeps tournaments on schedule and saves young bodies. The mental trap: kids treat it as a coin flip. It’s not — it’s a set, and the same rules apply: first four points matter enormously.
Timed matches. When a facility has a hard stop (indoor courts booked behind you), the referee can announce timed matches: most games ahead when time expires wins. It’s rare, it’s stressful, and it rewards fast play between points. If you hear “timed matches today,” tell your kid: no toweling off for 30 seconds, no staring at the fence. Play at a good clip.

How to Prepare Your Kid
Practice the actual format. If Saturday’s tournament is no-ad short sets, don’t practice ad-scoring full sets all week. Play practice sets in the tournament format — including the tiebreak. Familiarity is free confidence.
Teach the tiebreak rules before it’s 4-4. Who serves first, when sides switch, that it’s win-by-2. Kids who learn tiebreak procedure mid-tiebreak lose tiebreaks.
Adjust the game plan. In short sets, there is no feeling-out period — first-strike tennis wins. In no-ad, the returner’s choice of side at deuce is a real weapon: most kids return better from one side, and they should know which. In a 10-point tiebreak, treat points 1–4 like the whole match depends on them, because the whole match depends on them.
Be the Wall on Format Complaints
“This isn’t real tennis” is something you’ll hear when a format feels unfamiliar — usually right after a loss. Don’t join in. The format was the same for both kids. Be the parent who says “tough format today — what did you learn about playing it?” instead of the one lobbying the tournament director. Kids who adapt to formats become players who adapt to everything.
Takeaway Checklist
- ☐ Check the tournament homepage for the exact format before every event
- ☐ Practice in the tournament’s format the week before, tiebreaks included
- ☐ Teach tiebreak serving order and side switches at home, not at 4-4
- ☐ Short sets = no slow starts; no-ad = every deuce point is a set point for the nerves
- ☐ Screenshot the format table for the tennis bag
