Thanks, guys! So the WIAT doesn't provide an IQ number? I want a test to provide an accurate picture, and I was thinking an assessment might be better. However, my son is already getting an assessment from his English and maths tutor; although this is probably just a report on his abilities as yet, not his potential. Ugh, so confused. I am also having trouble finding a psychologist who performs the SB. Thanks for your help smile
