All that's required is that the student is safe on the firing line, they follow the line commands, and they keep an open mind toward instruction. We have a variety of methods to accommodate students of all ages who may not be able to physically work with the field positions we teach (prone, seated, and standing).
Come on out to the next event if you want to observe what we do. Better yet, sign up and experience it first hand.
Shay, I have personally seen a 5 year-old boy at one of our shoots who did just fine. He was on the line between his mother and father, was safe and listened to instruction. He did sit out a few strings of fire when he wore out or his attention span got stretched but he had a good time and we enjoyed having him on the line.
