So, you want to become a soccer referee? You will need to successfully complete an Entry Level Referee Course. There are actually two entry levels.

Level 9 Entry Level - The "recreational referee" entry level training course is an 8 hour course. It is designed to provide entry level referee skills and information through classroom and field training for candidates to referee youth games (U-11,12,13,14) at a recreational level only. Participants must be at least 12 years old prior to attending this course. This course is geared primarily to 12-13 year olds. Those individuals who are 14 or over should complete the Level 8 course. Administration of the USSF written examination is included. Minimum passing score is 75%.
