Are there special rules for the younger teams?
The 12U division plays with a lighter ball (Tachikara Volley-Lite), a lower net (70), and has special serving rules. If the player misses a serve from the normal line, she is allowed a second serve from five feet closer to the net. 12U players are generally not asked to referee unless they are comfortable doing so, and the scorekeeping is greatly simplified. All other age groups follow the standard rules.
