Did your son's psychologist discuss the ceiling issues with you?

I wonder if anyone else finds it interesting that even at the Davidson Institute, a place specifically geared for profoundly gifted children, age becomes a barrier to acceptance. My 4 year old is reading at a 5th grade level, doing math at a 3rd grade level and most comfortable with children twice his age or older. Why should children be limited by age?

Isn't this the very problem we have with a formal education?
My child can not begin school because of age. Intelligence and ability seem to be completely irrelevant.
