Thank you both so much! You certainly are the right people to ask! Unfortunately, I do not have the raw scores. You're right, Dottie--the 18 was for Information. The 19 was for Vocabulary. The rest of his scores varied quite widely--11,12, and 13 for Perceptual Reasoning, 12, 14, and 15 for Working Memory, and 10 and 11 for Processing Speed. (Honestly, I'm not sure what happens with arithmetic on this test. I overheard the neuropsychologist testing him on it and he didn't get to demonstrate what he's capable of. She commented that he probably would do very well on the Binet quantitative section, whatever that means.) I haven't had him achievement tested, but since he doesn't really read that well and he has his own idiosyncratic ways of doing math, I'm not sure how he'd do. If he could take a science achievement test, he would probably do extremely well on that!
