2018 AYSO Player Development Initiative 
Covers the referee implementation of 10U and 12U PDI in Section 1

6U & 8U
Throw-ins
Throw-ins are replaced by Kick-ins.  We have decided to stop allowing "dribble-ins".  The player must place the ball on the ground and kick it into play.  That player may not be the next player to touch the ball.  And, like throw-ins, no goal may be scored directly off of a kick-in, and opponents must be 2 yards away from the restart.

12U
Keeper Punts
Keepers are allowed to punt the ball in 12U

10U
Keeper Punts
No Punting
RESTART: IFK, if inside the goal area, ball is moved to goal area line parallel to goal line

Build-out line
For a goal-kick or keeper possession, the opponents must retreat behind the build-out line. 
If the keeper does not choose to wait, then an opponent who has not retreated is allowed to intercept the ball.  
This has been a cause for confusion.

Goal Keeper Possession
a. Opponents move behind BOL
b. Opponents may cross BOL once the ball is released from the Goal Keeper's hands
c. If opponents cross BOL before Keeper releases ball, and interfere with play:
 RESTART: IFK on BOL where infraction occurred
d.. Ball may be kicked to any point on the field
 

Goal Kick
a. Opponents move behind BOL
b. Opponents may cross BOL once the ball is kicked and moves
c. If opponents cross BOL before ball is put into play, and interfere with play:
RESTART: IFK on BOL where infraction occurred
d. Ball may be kicked to any point on the field

Build-out line is used to determine offside for 10U (no longer halfway line)
