AYSO has changed its training platform from aysou.org to EtrainU as of October 2021. The old AYSOU will still be available till around Christmas 2021. To access the new and current training platform, register as a volunteer in your region website say this one for Region 35 volunteers. Then you will see the AYSOU My Training button in the volunteer tab to access EtrainU, the new AYSO training platform.

If you are having challenges with EtrainU and prefer to use AYSOU until data migration stops, it can be accessed here.
