Will the pychologist see through this?

School have bought in a private Ed pych for my son, the peadatrician has said depending on what the ed pych report says and what his speech therapy report says then she will make a decsion on whever to diagnose him with autism or not, salt reports back and this verifys he has socail communication difficulties, im worried because my son behaves in school that that there will not be a great deal to report, saying that school bought in a private Ot who basically said he had spd too and he has hypercussis as well.

Anyway can ed pychs see through these things? i am hoping so, its been a long hard battle.
