Clarification: Was he tested by a PT or an OT? PTs generally don't deal with fine motor or visual integration. Gross motor is their area.
If he has dyslexia/dysgraphia, it is very likely that it is being masked at this point in his development, because of the shallowness of grade-level expectations, and his high cognitive capacity for compensation. If I recall, you also said you worked with him using a structured phonics-based program (TBT, All About Reading?) on reading, which would be the beginning stages of a dyslexia remediation/intervention, which might also mask an LD as far as scores go. If something like a CTOPP or PAL-II has not been administered, I would suggest that that should figure into the next round of testing, as they are more sensitive to the specific processing deficits of dyslexia/dysgraphia than standard cognitive and achievement batteries are. And if they were done, some more subtest analysis may be in order,to look for compensated dyslexic profiles.
