MLL, we have been over and over this. You will never get your DD's needs met at that school. Never. I would bet my last penny on it.
It is a private school - they don't have funding for additional needs, and they don't have access to the same assessment process as at a state school.
A friend of mine had a DD at a small caring independent school. They realised that her DD had traits of ASD. Their recommendation to her was that their school was not the right school for her DD - NOT because they didn't care. NOT because they didn't want a child with SEN (the school is a Christian school, and would never turn a child away, even if the parents were unable to pay the fees, they work something out) BUT they simply couldn't reach her needs, and give her the time, the expertise, the help she needed.
That little girl now has an AS diagnosis, and is going through the statutory assessment process. She has gone from no 1:1 but small class size, with some concerns, to practically full 1:1 provided by the Mainstream school while they go through the Statutory assessment process. This is a child who was only flagged as having SN at age 6 - until then she flew under the radar and was just 'quirky'. Now, there is no question of her diagnosis.
As Lucy grows, her needs are going to increase, because they are not being met, and they are not being managed, and she is not progressing.
Every EP will tell you 'she isn't bad enough for a statement', every one. Because they are employed by the LA, and resources are scarce. It is not their job to decide which children get a Statutory Assessment. It is their job to assess the child's educational needs and learning styles, their difficulties and their strengths, and make educational recommendations to help staff at the school meet those needs and enhance those strengths.
If I am honest, reading this thread has made me so
. Your darling daughter has spent years being criticised, maligned and faulted because she has SN.
Your DD has been at that school since she was 2, and they still can't meet her needs. It is a travesty
and you need to be brave enough to take her out of the school, regardless of whether they can give you a cosy chat in the morning, and move her to a school that can actually meet her needs, recognise her strengths and help her to overcome her difficulties.
This is NOT Lucy's fault, she is NOT being stubborn, non-compliant and disruptive, she is a child who is being FAILED. She is responding in the only way she can to the problems she is having at school. She is crying out for someone to recognise it.
My DD1 went to a private preschool (ie. community preschool rather than school nursery) because that's what we have in our area. They did their best, they were caring and kind, they recognised her SN instantly, we didn't know, and they gave her 1:1 for all 15 hours per week that she was there. She needed it. But every day was problematic, she couldn't cope, they didn't really know what they were doing. People would visit and say "use transistion sticks" then leave them a lollipop stick, and they didn't have the first idea how to use it. So they didn't. Visual timetables, used once or twice, then they gave up. DD1 was "stubborn, non compliant and disruptive".
Now, she has started a SN school and is in Reception. Her home-school book reports only positive parts of her day. She digs vegetables from the allotment, plays with wet oats to meet sensory needs, goes to assembly and they work with her to help her cope, even though she hates sitting down.
Please don't allow your DD to go unsupported any longer. Be brave, pull her out, enrol her in a state school, and get her needs met. Otherwise, you will have a 15 year old who is "stubborn, non-compliant and disruptive" and will have to face the adult world, where the support is gone. You either get it now, or have big trouble later.
