Thanks so much for the replies everyone. Just wanted to say that I agree with you all, and definitely understand these results are not fixed in any way at this age. The results of this test will in no way diminish the activities I do with my son, or change how I view him for the worse at all. I think my title and question were badly worded, I just wanted to be clear that I understood his FSIQ comes in technically below that line, particularly in this forum with so many HG+.
The purpose of having him tested was in order to get a bit more information about possible future educational options/decisions, as he'll be starting Transition (first year of school) next year (jan). He is also very anxious/sensitive and I had read that this can be associated with giftedness, so wanted to see if this was likely the case - basically in order to try and understand him a little better.
Aeh, thanks for the detailed response! You helped me understand the knowledge subtest a bit better. To be honest, I am still a little surprised at the score as we are a generally bookish family and DS is read to a lot as well as plenty of museum trips etc. To me, outside a test environment, his knowledge and vocabulary appears advanced. He has never been to daycare though, and we do minimal TV, so he may be sheltered in that respect. The psychologist commented that she felt that his knowledge scores would most likely jump up as he started attending school and gaining life experience outside the home. He is also very averse to taking risks and she said that he stopped/refused as soon as questions became slightly difficult for him.
