No. Coaches with no training certifications are required to attend the appropriate level of training. Training is a benefit. It makes coaches – even long time coaches – better coaches. And better coaches make a more enjoyable experience for the players.
For coaches that have been working outside of AYSO who possess a USSF certification, AYSO has a Coach Reciprocity Agreement in which they can be cross certified over to an appropriate AYSO coach certification. These coaches must still complete a volunteer application and have Safe Haven and CDC Concussion training in place.
