8U & 10U trainings (practices) take place one day per week, on the day of the coaches' choosing. All 8U & 10U matches are held at the WUSC fields on Saturdays. 8U matches are 6v6, with 5 field players and a goalkeeper. 10U matches are 7v7, with 6 field players and a goalkeeper. 8U & 10U matches typically have referees assigned, but coaches may step in to referee matches as needed. The US Soccer "Build Out Line" is used at both levels. "Offsides" is not called inside the Neutral Third (between the Build-Out Lines). "Offsides" is introduced at the 8U level with only flagrant offenses being called, and is fully enforced in the Attacking Third for 10U.
