I rarely post on here, but I just had to respond to your post. I just got the scores from my two children who participated in the same study. Both scores were much lower than I expected, with my now 6 year old's scores being almost absurdly low (he didn't test in the gifted range either). Similarly to your son, he's shown extremely advanced abilities from a young age (he taught himself to read at 2 years old, currently reads around a 6th grade level, is working several years ahead in math, etc). It was our first experience with testing too. The only thing I can think is that 1) the test took over 3 hours for him to complete (the tester ran out of questions to ask him on every sub-test) and 2) he's a relatively shy child who takes a while to warm up in new situations, so maybe those things played a role? I'm at a bit of a loss myself, but I just wanted to let you know that you weren't alone.
Did you see the note at the bottom of the page that many of the scores were lower than expected and they're still working on the extended norms? So, I wonder if it was the test and not our kids, kwim? I would love to hear how the scores from the study compared to the scores of children who had been previously tested.
