I should add that while I do think this forum has been really helpful in challenging my son without pushing him too hard, I do agree that I have not, and will not, have my son's IQ tested. I know that he is gifted based on observation - and three years of teachers have agreed with me. He doesn't need a number to prove that, especially since I genuinely believe that IQ does not accurately show intelligence. And there are many people out there who will use a high IQ score as a weapon - I'm not going to do that to him. That having been said, I do think he needs extra challenges, and this forum has been useful in finding those challenges for him.
