Teaching with autism

Good evening all,

I have just been diagnosed with autism. I feel quite happy really because I used to do and feel certain ways and I actually have an answer now.

I have a meeting with my headteacher (boss) on Monday is there any teachers here please? When speaking before about potentially been autistic last week. He said I would be the first in the schools history and they are here to support me anyway possible.

I don't know what sort of reasonable adjustments would be good for me. I've looked into a quite space and also looking at requesting help during my PPA time to make sure I'm using the time effectively. Also. My HOD ( head of department) is very last minute and disorganised so I'm mentioning to her also and the head that actually I need to know these things in advance. (I feel this won't change her at all)

Can anyone else think of anything else or if you're a teacher what I could ask or think about please?
