A point re: "Nice kid, really smart, does not really listen."

A brilliant person talking to me about DS once said, "Listening is about more than just receiving sound. He may hear, but that doesn't mean he can always listen."

I use this language when I'm talking to teachers about things that make it hard for DS to listen and execute: e.g., loud, chaotic settings. That is to say - every elementary classroom during every transition, every day.
