Ed psych may do a verbal comprehension test this term, but I think social skills intervention is more pressing. He has made strides but it's clear to me that the gap is widening. Superficially, with motivation, clear expectations, in a low stim or familiar environment he copes (ish). Otherwise he melts down tho he's learning to hide his distress in school & wait till pickup.
He's almost 7, I'd guess he'd be on par with an average 4y old... but he's good at remembering rules (lol) which masks things somewhat. I'm familiar with centiles for weight, language etc. Is there any better way of demonstrating the delay other than my largely unsupported assertations?
