General Referee Information

Referees, like the coaches, administrators and everyone else who makes our league “go” are volunteers. Most are the parents of players who begin when their children are playing in the youngest age groups and move “up” with them.  Some (especially those with significant playing or prior referee experience) start directly with the older kids.  All are welcome.
The best reason for being a referee is for the kids. Referees play a vital role in keeping the games safe, fair and fun - which is what Mt Diablo Soccer is all about; and is why the kids enjoy our region so much.
But why should you do it? While everyone is welcome, refereeing is especially likely to appeal to you if you like being involved (you tend to get fidgety on the sidelines) enjoy sports, even strange ones (you wish you were playing, instead of just your kids) enjoy (or need!) physical activity (reff'ing is a great, light, regular workout) don't have quite enough time, patience or soccer skills to be a coach. If any of these describe you, you should give refereeing a try.
When you do, you'll find out that it’s fun! Especially at the younger age levels, refereeing is not particularly stressful.  Your role is to help the kids structure their game as soccer and, occasionally, to intervene to keep it fair.  Best of all, you get to be out on the field with the kids enjoying the game “up-close”, while everyone else has to watch from the touch-lines.
Mt. Diablo Soccer has a very clear philosophy - its games are to be played so that they are a safe, positive, enjoyable, growth experience for the children. However, this is not achieved by adopting idiosyncratic or peculiar rules. Our games follow standard international soccer (FIFA) Law very closely, with only a very few changes to adapt to AYSO philosophy (e.g. controlled substitution to ensure that “everyone plays”) and, at the youngest age levels, to adapt the game to the physical and mental maturity of the players.
If you are interested in becoming a referee for Mt. Diablo Soccer, take the following steps:
  • Register as a volunteer for the current year. Visit and complete the registration. All volunteers MUST register every yearNew adult volunteers: we do require in-person verification of identification with a photo id (driver's license, passport, or state ID) - we have several in-person verification events scheduled, or the lead instructor can verify your ID in the classroom. You will not be able to complete the next step(s) until your ID is verified. 
  • Complete the Safe Haven Training for Volunteers online at You must have completed the volunteer application and had your ID verified before you will be able to log in to AYSOU. You only need to take this course once in your volunteer career, so if you have already taken the course, you do not need to repeat it.   Additionally, it is strongly encouraged that ALL referees also complete the CDC Concussion Awareness training course online at AYSOU. 
  • Register for the desired course on - pre-registration is encouraged, but walk-ins are welcome. Once logged in to click on Live Courses, then click on the Sessions button next to Regional Referee Course. Locate the course you'd like to register for, and click the Register button.
    Please note: AYSOU is a new system for AYSO national, and the course registration process does not have a search filter currently, the easiest way to find the course is to use your browser's Find feature (typically Ctl-F (Windows) or Cmd-F (Mac) and search on MDSA. 
The fall season is our main season. It starts around Labor Day and continues until the first week of November. Mt Diablo Soccer and the neighboring AYSO regions offer clinics and training courses that prepare (or refresh) referees for the season and are usually held during the late summer or the first couple of weeks of the Fall.


Safety Resources

The AYSO Incident Report Form is used whenever there is a personal injury, damaged property, or threats of or actual physical violence surrounding an AYSO game, practice, event or property. The form should be prepared by the Coach, AYSO Official, or other AYSO Volunteer. The form may also be prepared by a member of the regional staff such as the regional safety director, or by tournament or event staff members.
