Changing to special needs school

Hello,

I wonder if anyone can advise me please? My daughter is in year 6, she has learning difficulties, she's diagnosed autistic, dyslexic, dyscalcula and possibly dyspraxic. Her learning is at a pre school level. The struggle is causing her high anxiety. She is too nervous to ask for help.

I already signed her up for a mainstream high school but I've changed my mind. I would like to apply to other schools more suited for her needs. Where do I start? How do I change her school? I have considered the idea of home schooling until we find her a suitable place.

I think I need support for planning this. I am autistic myself.

Thank you for taking the time to read my message.
