I agree with MumofThree, that if its slow processing speed, the tester will calculate GAI.
With my ds who was just tested, she did additional subtests on another day, because block design was so bad. (He has some vision issues and is starting VT). Also, my ds has poor handwriting. It's not completely clear if it all the vision issue, but we are going to work on that. If the handwriting doesn't improve, we will more on to OT.
I did find it helpful to hear from the tester what she saw, where his strengths and weaknesses were, and her recommendations. As a side note, my ds loved the tester and thought going was fun.
Keep us posted!
