Has anyone had (or their child had) a QB test for ADHD?
My son had one today and his hyperactivity was 2.1, 98th percentile.
I should have asked more at the time but I was being distracted by my hyperactive child at the time - the usual 
I understand and work in percentiles but I don't understand what it's measured against.
Im told its measured against kids the same age who don't have ADHD.
So is he at the top of the hyperactivity scale? Do 2% are more hyper than him and 97% are less hyper than him?
How does that work if it's measured against children who don't have ADHD?
Are the 50th centiles NT and the 0.2% sloths?
I don't see how that would work?
Does anyone know?
(He tested in normal range for the impulsivity and concentration).
