When reffing an under 6 and under 8 match, who has the kickoff the 2nd and 4th quarter?USSF answer (March 22, 2007):
USYS rules are silent on the matter of a specific restart, noting only that (small-sided) teams at these ages play quarters of equal time, 8 minutes for U6 and 12 minutes for U8. Many leagues do not treat the quarter as equivalent to a half i.e., there is no specific restart because the instructions are simply to stop play (or use a convenient existing stoppage) near the quarter time mark. If the referee stopped play, the restart would be a dropped ball, otherwise it would be based on whatever else stopped play.
If you wish a definitive answer, you might check with the competition in which you play or officiate.
