My daughter was 10 when she was certified. She got her Jr. AOW at 11 and is a terrific diver. I do agree with the point that it very much depends on the maturity of the child. Sammi is a straight A student, very focused and a terrific athlete. Even so, I didn't push her into diving --it was something she wanted to do.
Now she wants to be a cave diver.
