SECTION 2 Part 1 – SafeSport (Adults only, not required for youth referees)
LiveScan requirements apply to “Regular Volunteers” which is defined as “a person who has direct contact with children 16 hours a month or 32 hours per year.” Most referees do not referee for that many hours (but it would be great if you did!) If it looks like you will, you can do the LiveScan at a later date. Or you can do it now.
Follow the instructions here to do your LiveScan:
AYSO LiveScan
SECTION 3 – Becoming a referee
In addition to the referee training, you will need to complete Safe Haven, Cardiac Arrest, and CDC/Concussion Awareness training in “etrainu” (also called "AYSOU", or "AYSO University").
“etrainu” is a separate training website where you can take online training courses for coaching and refereeing. It is accessed through the Sports Connect site; you must sign in there first (you can’t login to etrainu directly).
All AYSO referees will need to complete either Option 1 – the two Part Online/In-Person hybrid training class or Option 2 – the All-Day (8-hour) in person referee training course. The Castaic course is the Online/In-Person hybrid course.
Option 1 (for the Castaic course):
- Login to your account at Blue Sombrero/Sports Affinity. Click on the “Volunteer” button on the left-hand side of the screen. Under your name there will be an “AYSOU” button, click that button to open the etrainu system.
- If you do not see the AYSOU button under your name then you are in a family group that shows all your family names. You are probably logged into a family member’s account and are not logged into your account; the button only shows up if the person who is logged into their own account. Login to your account with your unique password and username and the button will show up.
- If you are logged into your account and the button does not show up then your background check expired and you will need to redo your background check.
- Once in etrainu – click on the “Training Library” button on the left.
- Click View Courses for SAFE HAVEN
- Enroll in and complete AYSO’s Safe Haven – Online
- Enroll in and complete CDC Concussions awareness – Online
- Enroll in and complete Sudden Cardiac Arrest – Online
- Click on the “Training Library” button on the left.
- Click View courses for Refereeing
- Enroll in and complete the “Regional Referee Online + In-Person Companion Course” course.
- Both courses must be completed - the "Regional Referee" portion must be done online before you attend the in-person course.

- Click on the “Training Event” Calendar button on the Left
- In the top part of the screen, type in Regional Referee, and a list of options will appear, pick the “Regional Referee – Online + In-Person Companion Course (2 Part Bundle)” option to help sort out classes.
- Search for “Castaic” and the course for Thursday 8/15 should show up.
- Attend the 3 hour in-person Referee Companion course you registered for.
(You can also search for other local courses, including the in-person only courses that take 8 hours)
FINISHED?
If you have done everything above or are renewing the required certifications to be an AYSO volunteer you should have the following completed:
1. Safe Haven – etrainu
2. Cardiac Arrest – etrainu
3. Concussion Awareness -etrainu
4. Regional Referee Training – etrainu + 1/2 day class time or ALL day class

7. California Mandated Fingerprinting – AYSO – AYSO 1441 Sports Connect your volunteer profile.Advice for youth referees and other volunteers.
- Additional Volunteer Users – users volunteering outside of the registration system will volunteer his/herself or add a new user to volunteer. If the volunteer now becomes an additional user, he/she will want to log in to the email account that was used to register the person as an additional volunteer and accept the invite to create a Username/Password on Sports Connect to get them access to AYSOU.
- AYSOU Certifications – Certifications will port over from AYSOU to Etrainu once the user volunteers, based on the system recognizing the volunteer ID. If the certifications do not port over, there is a mismatch in the ID. To ensure the best results DO NOT CREATE another account.
- All volunteers must have their own account tied to their own unique email address. A youth watching the videos on a parent’s account or a spouse watching the videos and doing the courses on their spouses’ account will not count and we cannot award credit after the fact.
