I agree with alot that has been said, and I think one test score does not HG/PG make....nor does one test score that did not show this mean a child is not. Kids learn at different paces and some catch up. But I believe that consistentcy is key. Is the child consistently over the years showing HG/PG, or is as someone said, the est the only thing in their gifted portfolio so to speak.
To be honest, when speaking of my DD I don' now exacly where she falls...she looked very highly gifted at 18 months and at 2, but I wondered if kids would catch up....today at almost 3 and 1/2, she is even further ahead of her age mates and not by my doing. I can't give her enough books, answer enough questions, give her enough puzzles LOL. But through all of that the way that gets me, and in my own personal belief growing up in a school for HG/PG kids....some who were leaps and bounds above where I ever could be, is not the difference in achivement or when they were able to do things, but the concepts that they were able to deveop and grasp all on their own....the way they think. I had the experience to be around kids from the time I was 6 till I graduated highschool who were all gifted to varing degrees, but their were those few.. that stood out to em then and stand out to me even today with the way their brains worked who were definitly PG. Ansey will say things that strike me as so out there, so deep and profound, that I am sent back to my youth and my experiences with these kids. The othere night I found myself tucking in a 3 year ld, but listening to her explain basically the time space continum and the physics of time to me...out of nowhere and never having heard anything like this before. To me, that is the difference, the Way they think...the uniqueness.
Anyway, that was probably rambeling, but in other words...I believe kids develop at differnt paces, the fast devloper can be caught up to by a slower devloping child and this can account for a lot of the fall back from giftedness...but I would be hard pressed to believe a HG/PG child could fall out of giftedness, as I believe it is the way the brain works is actualy different in these kids. Just my 2 cents worth LOL
