yes, my DD cant attend secondary school. she is doing only 3 GCSEs at adult evening courses at a local FE college, and is at home all day. With luck, and if the EHCP provides what it is offered, she will have someone to work alongside her to help her study. Then she will hopefully will receive funding to get the other 2 GCSEs she needs next year to get the minimum. LEA may fund because they recognise its their fault that she cant go to school, because of what happened, and because of the timescale.
With luck, and support in place, she can rejoin mainstream at year 12 for college. It will have taken 5 years to get her back to where she should academically be. in Year 6 she was one of the highest achievers at a tiny primary - she entered secondary in the top stream for every subject. She lasted 2/3rd of the first year, and 1 month of the second. 2 months in the 'specialist learning centre' with a woman who didnt believe it was anything more than my bad parenting, who threatened me and her, and said that if I took her privately she would get the diagnosis I paid for, and that was it for school.
Luckily, because of other healthcare complications, we had back up to prove I WASNT a shit parent, annd managed to get a GP referral to a specialist centre for PDA in Nottingham, funded by our local commissioning group, but this was after a private assessment which diagnosed ADD, and ASD.
If you have the support of the school for getting a diagnosis you really have it sewn up, as so often schools dont want to know
