Stress and anxiety - school avoidance

Our 12 year old daughter is ASD, ADHD and PDA. We have been in complete school avoidance since March of this year (since year 7) and have just now had agreement from the LA to assess for her EHCP.

Our daughter is academically around a year behind based on the assessment from her mainstream school, she is academically able but needs to be in a setting that is much smaller, provides focused support and accommodates her needs e.g. anxiety, sensory, which we believe is a SEN school.

Question 1 – We live in East Herts, what secondary school would you advise would be suitable? We have identified that Roman Fields/James Marks Academy might be a good fit but wondered if there were any others? Not familiar with the other SRP provisions e.g. Avanti Grange/The priory/Bushey Meads

Question 2-We have requested that the LA broaden its assessment to include OT and CAHMS/SENCO have also supported our recommendation. I there a list of experienced professionals in Hertfordshire that deals,specifically with autistic girls with sensory issues, ASD, ADHD and PDA, not wanting to engage with peers or parents ( school avoidance etc.) 

 Truly sorry for the long post, just so many questions and Thank you if you go this far Blush.
