Anyone aged 14+ can become a soccer referee through the process described at
http://www.epsarc.org/referees/become-a-referee/
This process includes a 4-6 hour online course followed by a field training session. Once qualified, referees can earn good money working at age-appropriate games.
Chester Upland Youth Soccer regularly hosts the field portion of the referee training program, providing free transportation, scholarships and referee gear to qualified applicants. If you are interested in learning more, please complete this form.
