Hi, my daughter has learning difficulties and possible PDA, a form of autism. After a very negative start to her school life, which caused all kinds of problems, we home educated her from year 1 until the beginning of year 3. She then went back to another school, but they started her in the year below, due to her learning difficulties etc. She then made friends and never moved up. The school have said that the LEA want her to move up but have always stressed that it's our choice. Because she hates change so much and is settled now in school with her own friends, we've never wanted her to move up.
Anyway, the other day, I phoned SENDIASS, the people who can organise for us to look at secondary schools for her and they made some calls and said that schools won't take out of year group, so she'll either have to miss year 6 or year 7! This did come as a huge shock. When I told the SENCO at school that she'd have to miss a year, at first she said, "not necessarily" I said that it was definitely the case, then she said "oh well, we did talk about this at her last meeting" Sounding quite defensive now. I said that we didn't and that I'd have remembered that! She then said "oh well, it's a new thing schools have bought in." After speaking to SENDIASS again, I know that it isn't new at all. 
We have decided that she will miss year 6 rather than year 7, so that means that her application will be late, we haven't even seen the school and there are all kinds of issues regarding her Statement being changed to the new format and her needing an ed psych report.
This has come at such an awkward time as she is starting to isolate herself, doesn't want to be around people, especially children, hates noise and is very anxious a lot of the time.
She doesn't know about all this yet, and we're waiting until everything is sorted out before we tell her.
Does anyone have any advice to give me, about how to prepare her for the news/ shock? What to get organised etc? Thanks.
