There are different definitions of normal, depending on the setting. Sometimes you will get reports that show mild normative deficits (such as you have here, with the exception of Manual Dexterity, which is more of a moderate deficit), but "within functional limits", which is more of a clinical judgment call, and doesn't mean that an individual is completely normal, but that they can get by with their activities of daily living. TBH, school-based OTs don't much like to suggest direct service (therapy) once kids hit middle school, as their experience usually is scads of no-shows and non-compliant students, even more so than for other service providers, like educational specialists and speech/language therapists. If kids won't engage, it's a waste of time for both service provider and client. Also, by that time, most kids have ingrained habits, which are quite intractable to remediation. Consequently, for borderline kids, they tend to lean away from treatment. This does not mean your kid doesn't have weaknesses in this area, or that he would not benefit from therapy, of course.
And, BTW, dyslexia is just another name for reading disability, and is absolutely a federal IDEIA qualifying disability. If you even mention OCR to the school, you are likely to get a whole lot more cooperation--although they won't be saying nice things about you behind your back. If OCR substantiates your claims, they really go over the school's behavior toward every federally protected class with a fine-tooth comb--even the ones you haven't complained about. No school wants to go through that.
