All players must be registered with a team in order to play AAU basketball. The maximum number of players a team may have is 15. All players must wear jerseys--the home team wears white and the visiting team wears dark colors. If a player gets into a fight, he must be ejected from the game immediately and must also be suspended for the next game. All teams must have an adult, non-playing coach. General basketball rules regarding gameplay, fouls and point-scoring are in effect in AAU basketball for all ages, and those rules must be officiated in order for a game to count toward a team's AAU record.
The ball's size should have a circumference of 28.5" (undersized basketball) for grades 1 through 6. Grades 7 through 12 must use a standard men's size ball. In fifth grade only, the leading team is required to play defense from behind the three point arc if a team goes up by more than 30 points. AAU athletes may practice by playing scrimmage games if non-playing adults are also in attendance. These games do not count towards a team's official record. Official games must be played on a gym floor with minimum dimensions of 84' x 50', and the gym must also be air conditioned.
Grades 1 through 3 play six minute quarters, grades 4 through 6 play seven minute quarters and grades 7 through 12 play eight minute quarters. If overtime must be played, grades 1 through 6 play three minutes and grades 7 through 12 play four minutes. All students have eight minutes for warm-ups and halftime.
