I'm not sure what your point isBecoming a referee:
Depending on your County FA either you can have theories sessions on one weekday and the weekday for a combined time of 20 hours of learning. Or one and a half weekends also for a combine time of 20 hours of learning. Which involves theory and technical practice. Thus being followed by the theory test consisting of 40 multiple choice questions being asked on the Laws of the game requiring 90% minimum to pass. With a maximum of 3 tries allowed before having to redo the course.
Being a referee:
After completing the 5 games of being a trainee referee congratulations you are now are qualified referee of varying levels based on your age (Y1 = 14, Y2 = 15, Lvl 7 = 16+). If you are Y1 enjoy trudging through 2 years of juniour football learning and prefecting your craft. Or if you're Y1 enjoy slogging through 1 year of juniour football learning your craft. And if you're a Lvl 7 you have a choice be pressured by appointment manager to go straight into open age due to the severe lack of referees or spend x number of years doing junior football learning and prefecting your craft. However during your next two years of refereeing if you last longer than that you are in the top 75 precentile of referees. Don't worry you will only experience abuse from players, spectators and fans. With 93.8% of referees saying they experience abuse.
Post referee:
Getting to this stage you either quit due to abuse being driven to your breaking point. Retire due to old age. Or no longer have the time refereeing. But don't worry I am sure there might be a chance someone will replace you.
