You do not need a ranking, a tournament, or a coach to start. Tonight, after practice, log it: what they worked on, how long, how good the work was, 1 to 5. That is a day won. The vocabulary below you will pick up as you go.
How scoring works (the 5-minute version)
- Points → games. 0 is "love," then 15, 30, 40, game. At 40–40 ("deuce"), traditional scoring needs two points in a row; many junior events use no-ad instead: at deuce, the next point wins the game, and the receiver picks the side.
- Games → sets. First to 6 games, win by two. At 6–6, a tiebreak (first to 7 points, win by two) decides the set.
- Sets → match. Usually best of 3 sets. Many junior events replace the third set with a 10-point match tiebreak: first to 10, win by two. It's fast and brutal, which is why the mental game matters so much.
Tournaments: how the ladder works
In the U.S., most junior tournaments run through the USTA. Events are tiered by level: entry-level local events up through sectional, regional, and national championships. The names vary by section, but the shape is the same everywhere:
- Local events: round-robins and one-day matchplays. Low stakes, high learning. Live here for a while; it's where match craft is built.
- Sectional-ranking events: multi-day draws, seedings, consolation brackets. Results start feeding rankings.
- National-level events: for later. The pathway is long by design.
The full ladder, Level 7 to Level 1, with who gets in and how the points work, is in USTA tournament levels explained. Players also compete outside USTA: high-school tennis, UTR-rated flex leagues and verified events, and team formats like Junior Team Tennis.
The ratings alphabet: WTN, UTR, rankings
The long version, with what feeds each number and why a win can lower a rating, is in UTR vs WTN vs USTA rankings.
| Term | What it is | What to know |
|---|---|---|
| WTN | World Tennis Number, a global rating from ~40 (beginner) down toward 1 (pro) | Lower is better. Updates with results. The number every USTA player now gets. |
| UTR | Universal Tennis Rating, 1–16+, higher is better | Widely used for college recruiting and level-based matchplay. |
| Ranking | Points earned in your section's tournaments | Measures activity + results in your section, not pure level. |
Tournament-day survival kit
The full day, from check-in to the handshake, with a printable version of this list, is in Your first USTA tournament.
- Two racquets minimum (strings break), water + electrolytes, snacks that aren't sugar bombs
- Layers: matches start at 8am cold and finish at noon hot
- A printed or screenshotted draw; know the check-in desk and default time
- Sunscreen, a chair for you, and a charged phone (you're the scoreboard now)
- Patience: a "9am match" means 9am or whenever the court frees up
What great tennis parents do
- During the match: stay neutral. Players police their own lines and scores in juniors; that's the deal. Cheer good points (both kids'), say nothing about bad calls.
- After the match: the car ride home decides whether tournaments stay fun. Lead with "I love watching you play." The parents' guide has the full playbook.
- Long term: measure shows-up-and-works, not trophies. TierBreak's whole design exists to make the process visible so results can take their time: streaks, weekly reviews, proof from real points.
Where TierBreak fits from day one
In this order: log practices and win days for a week, track a match at a low-stakes event with two taps a point, read the Weekly Review together on Sunday. The Mental Pathway comes after the habit holds, and it is worth starting young: a ten-year-old who learns to breathe between points has a real edge at fourteen. By the time ratings matter, you will have years of the work written down behind them.
