ITT 3.0 at ATCC
Five nights of coed team tennis: round robin, semifinals and finals.
What is ITT?
Impact Team Tennis is a national coed team tennis program that grew out of World TeamTennis, the league started by Billie Jean King. Players across the country compete on local teams, and league winners can advance to Regional Championships and the ITT Nationals.
Each team has at least two men and two women. A match is six fast, no-ad sets on two courts: men's and women's doubles, men's and women's singles, and two sets of mixed. Every game counts toward the team total, teammates can sub in, and cheering and coaching from the sidelines is encouraged.

All times are Pacific. No play on Thanksgiving, November 26. A three-round full round robin assumes four teams. Suggested semifinals: seed 1 vs. 4 and seed 2 vs. 3. Each team match uses two courts.
Who can play?
The average of the two highest-rated men and two highest-rated women on the entire roster must be 3.0 or below. Lower-rated reserves do not lower this average.
Men: 3.5 + 3.0 · Women: 3.0 + 2.5
(3.5 + 3.0 + 3.0 + 2.5) / 4 = 3.0 — eligible
Guest policy: non-members
Up to 20% of each team's roster can be non-members. Everyone else must be an ATCC member.
A non-member cannot already play on another ATCC team. If a guest is on any other ATCC team, they are not eligible to join an ITT roster as a non-member.
Example: a 10-player roster can include up to 2 non-members.
Register before the first match
Captains register their team on ITT. Every player registers individually and joins the roster. For ATCC, each player must have a USTA profile and add their USTA number. These ITT results do not affect your USTA NTRP rating.
Registration FAQs
Who registers first? Each team has one main captain (plus an unofficial co-captain). Only the main captain registers the team.
When do teammates register? After the captain's team is created, teammates register and join it.
Which league do I pick? Choose Thursday 3.0 Altadena in the drop-down menu, even though one night (Nov 4) is a Wednesday.
Regional advancement: one team, the league winner, qualifies for regionals. ITT allocates one qualifying team per four teams in an official local league division.
How the lines work
Six sets per team match, played in three waves across two courts.
| Court A | Court B | |
|---|---|---|
| Wave 1 | 1 · Women's doubles | 2 · Men's doubles |
| Wave 2 | 3 · Women's singles | 4 · Men's singles |
| Wave 3 | 5 · Mixed doubles | 6 · Mixed — MONEY COURT |
These are scorecard positions, not ATCC court numbers. With two team matches running, repeat this layout on a second court pair.
Scoring at a glance
| Game | Set | Team match |
|---|---|---|
| No-ad: four points win. At 3-3, one deciding point. | First to 6 games. At 5-5, use a nine-point tiebreak. | Add games from all six sets. The Money Court determines whether overtime is needed. |
On a deciding point in mixed doubles, men serve to men and women serve to women. Players cannot appear in both mixed doubles sets, including as substitutes.
Substitutions & lets
A reserve can change the lineup while the service and receiving positions stay fixed.
| Situation | What happens |
|---|---|
| Singles: Alex replaces Ben | Same-gender substitute enters after a point. Ben cannot return to that set. |
| Doubles: Cara replaces Dana | Cara inherits Dana's receiving side and service slot. The partner keeps both positions. |
| Player already played set 5 mixed | That player cannot enter set 6 or its overtime. |
| Set 6 continues into overtime | It is the same set. An eligible unused mixed player may enter; a player removed from mixed cannot return. |
| Super Tiebreak begins | It is a new set. Substitutions are allowed; partners may reset receiving positions. |
Doubles rotation example: Dana › Opponent 1 › Partner › Opponent 2. After Cara replaces Dana: Cara › Opponent 1 › Partner › Opponent 2. Cara takes Dana's deuce side; the partner stays on the ad side.
Money Court & service
Set 6 keeps the comeback alive.
| Match total / set 6 result | Next step |
|---|---|
| Leading team wins set 6 | Match ends. |
| Trailing team wins set 6 | Continue set 6 into overtime. Leader wins one game: match ends. Trailer ties the total: Super Tiebreak. |
| Overall total is tied | Go directly to the Super Tiebreak. |
Example: A leads 28-26, but B won set 6. B wins two overtime games: 28-28, so play a Super Tiebreak. If A wins an overtime game first, A wins the match.
Who serves first?
Home or away? Captains spin a racquet before the match. The team that wins the spin chooses whether to be home or away.
Home starts sets 1, 2 and 6; Away starts sets 3, 4 and 5. Receivers choose the end. Overtime continues the set 6 service order.
Tiebreak service map
| Format | Service turns | Finish |
|---|---|---|
| At 5-5: nine-point tiebreak | A: 1-2 · B: 3-4 · C: 5-6 · D: 7-8 · D serves point 9 if needed | First to 5. Change ends after 4. |
| Tied match: 13-point Super Tiebreak | A: 1-2 · B: 3-4 · C: 5-6 · D: 7-8 · A: 9-10 · B: 11-12 · B serves 13 if needed | First to 7. Change ends after 6. |
A and C are partners; B and D are opponents. Each two-point turn starts on the deuce side. On the final deciding serve the receiver chooses the side; mixed is gender-to-gender. No two-point margin. The Super Tiebreak starts with a new coin toss.
