Evaluate for sensory issues, auditory processing issues, AND AUTISM. Yeah, sorry, I don't care if it's been ruled out. Still sounds like it.
I'll tell you I had Autism (Asperger's specifically) ruled out by a professional for DD1 and a year later she got the diagnosis. You know what? I had ruled it out myself. She didn't fit the symptoms in a classic manner, so it was really easy to over look with a quick evaluation. It took a 4 hour in depth evaluation to be able to identify it. Now it seems to scream out at me like neon signs.
Anyway, if the school is willing to do the evaluations, I don't think it could hurt.
