Did he have any tests for autism?
He had GARS-3, and nothing unusual really was apparent there, which I expected when filling in the questionnaire sheet. I had wondered if this tests is typically used for those who are on the higher functioning end, because it seems like it would miss quite a bit. I could be completely wrong, since I'm just guessing.
Push school to test him even if they think they know the outcome. What you say here would be red flags and I think the school would hopefully hear you out and agree to test for autism.
Thank you!
