How to Access AYSOU:
-
First, you must be registered as a volunteer at ayso157.org — either as a Referee, Coach, or Board Member.
-
After completing your volunteer registration, please allow 24 hours for the AYSOU link to become available.
-
Once available, log in to your account at ayso157.org.
-
Navigate to your Account page and find the Volunteer panel — you’ll see the AYSOU button there.
If you need help accessing AYSOU, see the “What if I don’t see the AYSOU button?” section or contact [email protected] for assistance.

Click on the Volunteer link from the Account page.
Click on the AYSOU link to get into the training site.
Note: For households with multiple persons in different volunteer roles, you will need to make sure that you properly log out and log back in so that when you take training, you are taking it under your learner account versus someone else in your family. AYSO157 and AYSOU use single-sign on tokens which can sometimes get confused. To be extra sure, start each session in an Incognito window, log into ayso1.org and then access your account and AYSOU button.What if I do not see an AYSOU button?
If you do not see the AYSOU button on your account, it may be due to one of the following reasons:
-
You are not logged into ayso157.org using the same account under which your referee or coach volunteer registration was completed.
-
You just completed your registration, and the system has not yet updated. Please allow up to 24 hours for the AYSOU button to appear.
If neither of these resolves your issue, please contact [email protected] for assistance.
