JOIN THE YOUTH SOCCER COMMUNITY


Become an AYSO Youth Referee

AYSO offers a great opportunity for players ages 10 and up to get involved as Youth Referees.

Youth referees play an important role in supporting younger players while developing confidence, leadership, and decision-making skills. Referees can choose the number of games they officiate and work around their own schedule.

No prior experience is required. Training and support are provided.

Why Become a Youth Referee?

  • Earn community service hours
  • Build leadership and communication skills
  • Stay active and involved in the game
  • Gain confidence making decisions
  • Develop a deeper understanding of the rules, helping you become a smarter player
  • Support younger players in a positive way

How Youth Refereeing Works

  • Youth referees can officiate games for younger divisions
  • You choose the games that fit your schedule
  • New referees are supported by experienced referees, coaches, and the referee team
  • 06U games do not use referees; coaches serve as game leaders at this level.

8U Referee (Minimum age: 10)

  • Online training only
  • Eligible to officiate 07U and 08U matches

Regional Referee (Minimum age: 12)

  • Online training plus in-person field session
  • Eligible to officiate 09U and 10U matches

Getting Started

Step 1: Set Up a Unique Email Address

Before registering, your child must have their own unique email address.

  • This cannot be a shared email for multiple people, as it is tied to each volunteer’s individual AYSO account, training records, and access to AYSOU
  • Your child will use this email to log into AYSOU and complete their online training courses

If your child does not already have an email address, please create one for them.
For children under 13, this email should be managed by a parent or guardian.



Step 2: Start Registration from the Parent Account

Log into your account and:

  • Click My Account
  • Select “Volunteer” from the left-side menu

Then:

  • Click “Find Volunteer Roles”
  • Select “View Divisions” under the Referee Program
  • Select Referee, then click “View Selected Opportunities” in the bottom right


Step 3: Add Your Child as a Volunteer

You will now select the user who will be volunteering.

  • Choose “Add New User” to add your child
  • Enter their information and complete the required waivers
  • Click “Invite User and Continue”

An email will be sent to your child’s email address with the subject:
“ACTION NEEDED: [Parent Name] volunteered you to be a Youth Referee”


Step 4: Accept the Invite and Create the Account

Open your child’s email and click “Accept Invite.”

Important:

  • If you are still logged into ayso599.org as the parent, log out first
  • If prompted, select “Use another account” and enter your child’s email

Complete the account setup:

  • Verify the email address
  • Confirm name and birthdate (this is the last chance to update without support)
  • Select “Other” for relationship
  • Add contact information and save

Your child now has their own AYSO Volunteer Account.


Step 5: Complete Training

Most training is done through AYSO's training system called "ASYOU". 
You must be logged in as your child for them to complete referee training.

  • Always check the top bar to confirm who is logged in
  • The AYSOU button will only be active when logged into a volunteer account
  • Be careful not to complete training under the wrong account, as this is difficult to correct

👉 See AYSO Volunteer Training page (background check, LiveScan, Safe Haven and SafeSport are not required for youth volunteers; remaining safety trainings are required.)



Step 6: Complete Referee Training

👉 See Referee Training & Certification page



Step 7: Start Refereeing


Once training is complete, your child can begin signing up for games that match their level and comfort level.

New youth referees are supported and often paired with experienced referees for their first games.

And yes—this was the hardest part.
