Maybe it would help if you could give us some idea what kinds of difficulties your child is experiencing in school? I am no expert on IQ tests, but I know my own kids tend to have unusual scatter, and this seems to go hand in hand with experiencing specific roadblocks while learning. By a "roadblock" I mean a problem/difficulty which once overcome (which can happen rather suddenly) then leads to very rapid learning in that area. I think children with that kind of learning profile might be more challenging to teach. I enjoy that challenge though (at least with my own children). These "roadblocks" seem different from learning disabilities in the sense that once overcome they are no longer a problem. I suppose another way of saying the same is my kids in some areas are late bloomers, but they do bloom impressively when it is their time to do so. I am not sure what a LD profile would look like on an IQ test, but maybe it could be similar? Your child has impressive scores on the verbal section, by the way!
