Ds's school have finally admitted they cannot meet his needs which are incredibly complex and we know that there are no schools in county that will be able to meet them. He has acute anxiety which is getting worse and is now close to permanent exclusion due to his behaviour when anxious. He has a year until secondary but we can't see him lasting at current school even until Christmas 
. Proposed sm has been issued with not a lot quantified and vital needs omitted e.g ongoing OT and SaLT 
. It is clear that LA wants him placed in a ms unit which they have yet to staff and set-up and will therefore be untested in dealing with dc's with his condition.
We have to get him out of his current school urgently and I asked in a recent meeting where he would be placed when he gets excluded and there was no answer to that! They have already placed him in a PRU on a 'course' and he's not going back there!
There is a specialist independent school out of county that we are visiting shortly that, after seeing his paperwork and assessments has already indicated that they would be able to meet his needs (but would have to be residential because of distance).
Now, should I bother spending time making all the amendments to the sm or just name the school we want in Part 4? Do I tell the LA that I don't agree with parts 2 & 3? If I do will they expect me to tell them why and want ongoing discussions which will waste time? They have pointed out that they have until 15th Feb to name a school but I have said that I need to lodge tribunal appeal asap.
Also, what can I do now to get him out of his current school?
Would be grateful for any advice.
