Hi Momofone,
I read somewhere that the optimal testing age is 7.9. Consider testing again (or with a different test) in a year. I have seen 2 cases of friends whose children tested a standard deviation above their first test, administered at a young age (about 6). You never know what goes on with the tester-student (is the student un-interested? is the tester impatient or intimidating? is the time of day that sleepy time? All kinds of things). I distinctly remember my testing experience as a high schooler and being self-conscious & shy (not a good thing when your responses are timed!)
