What rules does my child play under in 14U club water polo? Eligibility, game length, ball and cap rules, fouls and exclusions, cards and injuries.
USA Water Polo-sanctioned 14U games use the USA Water Polo Rules 2026-2027, which are based on the World Aquatics rules. National championships (National Junior Olympics, its zone qualifiers and Champions Cup) also follow USA Water Polo's Conduct of Championships, which sets 14U-specific details such as period length, ball size and eligibility.
14U plays the full rules. USA Water Polo's modified rules for younger players (no direct shot from a free throw outside 6 meters, no set exclusion time, smaller goals, goalkeeper can't cross half pool) apply only to 12U and 10U.
Key 14U differences from adult play come from the Conduct of Championships: a size 4 ball for boys and girls and 6-minute periods at Junior Olympics finals and Champions Cup.
For USA Water Polo national championships, under the Conduct of Championships:
A game is always four periods of actual play: the clock stops at every whistle and restarts when the ball is put back into play, so a game takes much longer than the clock time.
| Period length | Breaks | |
|---|---|---|
| USA Water Polo Rules default (WP 12) | 8 minutes | 2 min after periods 1 and 3, 3 min at half time |
| National Junior Olympics Championship Finals, 14U | 6 minutes | 2 min (Qualifying Division) |
| Champions Cup (14U) | 6 minutes | Rules default |
Ties: where a result is needed, a tied game goes straight to a penalty shootout: each coach names five shooters plus a goalkeeper, teams alternate shots, and if still tied after five each, the same five keep shooting until one team scores and the other misses.
Size 4 (the women's compact ball) for both boys and girls at 14U.
USA Water Polo's Conduct of Championships sets these ball sizes for the National Junior Olympics and Champions Cup:
| Division | Ball |
|---|---|
| 16U and 18U boys | Size 5 (men's) |
| 14U boys and girls, 16U and 18U girls | Size 4 (women's compact) |
| 12U boys, girls and mixed | Size 3 (intermediate) |
| 10U girls and mixed | Size 2 (junior) |
Under the USA Water Polo Rules (WP 3), a women's ball weighs 400-450 grams, measures 0.65-0.67 meters around and is inflated to 6.5-7.5 psi.

At USA Water Polo national championships, a 14U team needs a rostered coach and 7 eligible players ready at game time or it forfeits 5-0. Junior Olympics zone qualifying rosters can list up to 18 athletes.
Under USA Water Polo Rule WP 21.14, a team may keep the ball for no more than:

The shot clock resets:
The same shot clock applies at USA Water Polo national championships, including 14U.
An exclusion is water polo's version of a penalty box. Under USA Water Polo Rule WP 22, the other team gets a free throw and the player must swim, without leaving the water, to the re-entry area at the corner nearest their own goal line.
The player (or a substitute) can come back in after the earliest of:
Common exclusion fouls include holding, sinking or pulling back an opponent who doesn't have the ball, intentionally splashing an opponent in the face, blocking a pass or shot with two hands outside 6 meters, and interfering with a free throw.
