I'm just starting this again for this year (my 8yo seems to have anxiety and outbursts--couldn't even make it through one week, so it's time to chat with her new teacher!). We're finally asking for an eval. So I've just been reading that you can get a 504 for that. Sounds like it might be worth it in your case so you can get some appropriate responses in place for when the anxiety causes a disruption. Just some beginning info, I'm sure there are lots who have really been through it who can speak with greater insight.
