Hi Asdx
Sorry to hear you'v had such bad news from the Paed. Sometimes we're all so busy just getting though the day we don't notice when situations are gradually deteriorating.
My DS was also 15 when his problems came to a head and he needed residential care, so I have some experience to share with you.
The first and most important thing is to keep him in school. If he leaves school he is no longer the LA's responsibility.
The help that he needs can only be provided in a socio-educational-health setting and that's what the Paed is trying to set up - it's called a tripartite funded placement for which the NHS, Education Service and Social Services all chip in their funding.
These are mainly independant sector settings that provide this comprehensive care but they are are very, very expensive - think upwards of £80K per year. You can see why the SS are telling you that you don't qualify.
Don't believe them.
Getting him help very quickly is important as he approaches the age of 16. As long as you keep him in school he remains the responsibility of the LA and his Statement (if he has one) remains in force, so it's up to the LA to identify a suitable placment in conjunction with the SS and NHS.
Unfortunately the Paed cannot secure this placement for your DS on his own. It'll be up to you to press all 3 sides to make that funding available.
To do that you'll need to prove need. The paed should put his concerns in writing to the LA and also to SS. Paeds are very good at telling you what's needed and very slippery when it comes to committing themselves in writing - their employer-the NHS discourages them from doing so as they would have to pick up the bill - so you can see why you'll have to get really involved to make this happen.
So I'd start by asking the Paed to produce a written statement of your DS's difficulties and his recommendations for a suitable placement. He should send copies to LA and SS.
You, at the same time, should be requesting that the LA review your DS's Statement and submit as evidence, the Paed's letter.
You should also be requesting an SS assessment of your son's needs in light of the Paed's report and also an assessmnet of your own needs as a carer.
At 15 he should have had a Transition Review. That's when Ed Pysch, SS, Paed, LA, Head all get together to plan the future for your son post-16. It's called a multi-disciplinary review and should be called by the Head of your son's school. If you haven't yet had that you need to write to the school and remind them.
You'll also need to strat investigating what provision exists for him - placements such as the Priory Group of FE Colleges and the Wing Centre in Hampshire.
This will be a difficult placement to obtain so you'll need to start immediately, investugating, gathering the evidence of need and kicking those who should fund it, as they will undoubedtedly drag their heels.
I am so sorry that you are faced with this while your DH is so unwell.
Best wishes
