Re: Supporting the less able...
couldn't you offer them courses in your dojo if that's logistically possible? Then they should be covered like any other student.Your foundation couldn't possibly reject that, could it?
Our dojo is in vicinity to a state boarding school for children from problematic households (children who have been taken away from violent parents, parents parking their kids there while they do a detoxication cure, children just abandoned by parents who don't care...) and in the last years we always had some students coming from there. They were insured like anyone else, and they weren't more or less violent than the rest of us. None of them stayed until reaching a high grade, but then none of the other kids does, neither (there is some room for improvement in kids' permanence).
I wih you much luck wiht your endeavour!
