No, if its agreed she meets the criteria (and it sounds like she will), then the care and support plan (= Part 3 of the statement) leads on from the assessment of need (= Part 2 of the statement). There should also, as part of it, be a carers' assessment on you, which leads to a support plan for you.
Has she been assessed by a speech and language therapist? If she hasn't, I'd request an assessment asap!
Is she in an NHS ward/unit? I'd look on their website for their policy on learning difficulties. Under the Equality Act 2010, they have to make reasonable adjustments for disabilities, such as comprehension difficulties. My nearest hospital has an A4 "All About Me" folder for people with learning disabilities/dementia to show professionals, which has sections on comprehension, how to communicate with me, etc! There are also two learning difficulty nurses to accompany a disabled person and carer to appointments; ensure the disabled person is enabled to understand the doctor's message, etc. Appointments are supposed to be the first in the clinic, double the time and in a quiet room.
It would be a reasonable adjustment for the OT/physio to slow down their language, speak clearly, model the desired actions or whatever your daughter needs for her comprehension. Paediatric physios and OTs are usually very good on this, because so many of the children they see, also have speech and language difficulties! Its not enough for them to walk off, session over, because of her disability!
