Instructions
Please READ THE INSTRUCTIONS CAREFULLY, and follow the steps to the letter! If you have any questions, please contact the Director of Referee Instruction.
- Register as a volunteer in Region 10 by following all of the steps in this document. (If time is short, you may complete the safety courses AFTER you complete the Regional Referee course).
- Locate the AYSOU referee training courses:
Log into your Region 10 volunteer account by clicking "Login" or "Register Now" at the top of this page.
Click "AYSOU" in the left menu.
Click "Training Library" in the left menu
Find the "Refereeing" block and click "View Courses."
- Complete the age-specific training course:
- To referee in 8U or younger (in Fall and Winter), find the "8U Official - Online" block and click "ENROLL." Take all the modules in order, including the exam at the end.
To referee in 9U or older, or 8U Spring Select, take either the "Regional Referee - Full In-Person Course," or the "Regional Referee Online + In-Person Companion Course." The Full In-Person course does not have an online training requirement, but requires a longer in-person session. Both should take roughly the same overall amount of time.
For the Full-In Person course, locate the course block and click "ENROLL VIA EVENT." You will be able to search for available course offerings. It is recommended that you click the "X" next to "Region 10" in the "Regions" box and enter your zip code and desired range in the "Location" box to find available courses offered by Region 10 and other nearby Regions. Click on your desired course and then click "Enroll." Be sure to read all course information and prerequisites. Some of the course offerings are listed below.
For the Online + In-Person Companion course, locate the course block and click "ENROLL." Take all the modules in order, including the exam at the end. You must complete the online course before coming to the in-person class. It is recommended that you take a picture of your completion certificate to bring with you to the in-person course. To complete training, you must also enroll and come to one of the in-person companion classes - Part 2 of the 2-part bundle. Click "Training Event" in the AYSO menu bar to search for available courses. In the "Courses" box, search for and select "Regional Referee Online + In-Person Companion Course." It is recommended that you click the "X" next to "Region 10" in the "Regions" box and enter your zip code and desired range in the "Location" box to find available courses offered by Region 10 and other nearby Regions. Click on your desired course and then click "Enroll." Be sure to read all course information and prerequisites. Some of the course offerings are listed below.
- If you do not receive a referee uniform upon completion of the course, please contact the Referee Uniform Coordinator to obtain a uniform.
