Referees are as critical to soccer as players and coaches. In AYSO, the game can’t be played if there aren’t enough referees. All AYSO referees are volunteers.  AYSO’s referee training is considered some of the best in the U.S. and includes both in-person courses in your community and online opportunities. Soccer knowledge is a plus, but is certainly not required. The AYSO referee training will give you all you need to know to have a terrific experience on the field.  For a schedule of available referee training, go to the www.aysotraining.org.

The build-out line is a component of the USSF's Player Development Initiative. It designates special rules in the 10U game that relate to offside and goalkeeper distribution.

First adopted by AYSO in the 2017/18 season it continues to evolve in minor ways each year.

Here's is the latest incarnation of the rules surrounding the build-out Line. It also explains the rationale behind the decision to implement this initiative and how it relates to the modern game.
