Especially if the teacher is concerned about him, then one of your options is to have the school district evaluate him for possible learning disabilities (some possibilities: reading disability, receptive/expressive language disability).
That would address primarily academic/school-based concerns. But CAPD would fit many of the symptoms, and you would need a clinic-based evaluation by an audiologist for that, which requires a referral from your physician. If your insurance allows, you could also request a referral for a neuropsych, preferably at a hospital or clinic, where you could have an audiologist on the same team do the CAPD testing.
Given the range of possible issues (LDs, vision, CAPD, attention, social responsiveness), there may be some advantage to having a clinic/hospital-based team do the whole evaluation, rather than going through the schools, which most likely won't have the resources to follow up on the vision, and very likely will not be able to do the CAPD testing.
