:iagree: I had my son tested right before he turned 4.
I wanted to know just what I was dealing with. I knew he was "ahead," but I didn't know if he was ahead enough that he would require special schooling.
Even though we don't need his IQ score and achievement testing for HSing, it's reassuring that what I am seeing as gifted, is in fact gifted, and it's not my "mommy goggles." I was of the thought that everyone thinks their kid is a genius, so I was probably just biased.
As far as the "how do you know," The Ruf levels are a good place to start, or you can google "signs of giftedness in children."
FWIW, I now prefer the term, "asynchronous learner," over the word "gifted." :D Gifted is such a loaded word, and means something different to everyone.
ETA: Apparently I like to use "quotes" a lot.:lol:
