My son would like to start judging, he has done all the seminars. Just wandering is there a certain age you have to be before you can start?

Theres no age restrictions, I past all exams by age 14 and was on 2 breed clubs at 15, but didn't accept appointments till I was 16, just so people would give me abit more respect.  How old is your son?  If he ever wants to talk about judging as a young person I have afew tips.  I have been given alot of encouragement and advice, not everyone has supported me, but a large majority have.  I have felt welcomed, and Some big names have been impressed when I ahve spoken to them in judges reception.
