To get a special school placement, or a LSA, you need an EHCP in the vast majority of cases (in my area anyway). The OP’s DD’s school are not helping her get one so she can get access to support but are trying to off load her instead which is disgusting and not uncommon. It takes a long time to go through the EHCP process, you’re looking at a minimum of 5 months but that’s only if the LA keep to timescales which they don’t IME.
Having experienced similar, I can well believe a malicious referral to SS OP. Makes me wonder if your DD is at the same ‘outstanding’ secondary school as my DC was! Sorry you are experiencing it too.
We never had a referral to SS but I wouldn’t have put it past the school. They tried every dirty trick in the book to try to piss me off enough so I’d remove my DC. Head took it personally that I held him to account for their failure of duty to my DC. He even sent me an email once saying I was rude to blank him (those exact words) because I didn’t acknowledge him at parents evening after I was told my DC would not be entered for any GCSEs and I had walked out of a meeting where he had asked why he had to have my child in his school when they obviously didn’t want to learn and he had a waiting list of kids who did!
DC has ASD and a learning disability but it took 3 attempts and until Yr10 to get an EHCP.
I wouldn’t be too concerned about the SS referral, just go with it. It is utter nonsense to say you are denying her an education if you are trying to get here there despite her distress. In fact, even with this going on, I’d email the Head putting in a formal complaint that they are denying her access to an education by not putting support and reasonable adjustments in place (you sitting there is not THEM supporting her and is totally inappropriate). Escalate to Board of Governors or Academy Trust.
How on earth can they suspend her for meltdowns - do you have that reason on the suspension letters? Add that into the complaint as well as the meltdowns were obviously due to her being unsupported.
I’d also say that you will not be returning her to school until a meeting laying out a support program and strategies is arranged as she’s not safe in school if she’s self harming.
When you get the SS conclusion, make sure you put in another formal complaint about the malicious referral, all the way to the Department of Education.
I honestly boil with anger even now years later when I think of how much I let my DC’s school get away with so as not to cause a fuss and be labelled a problem parent! They bank on that.
