LEA wants a meeting with MS school, LEA, parents, EP and ASD outreach asap and urge me to get DS back to school with the additional provision they proposed
We had a meeting like this before we got our statement. This is where the SEN officers make it clear what line they expect school etc to follow. Chances are they have the EP and ASD outreach (who they employ) all geared up to put pressure gang up on you / school. If school resist they will probably face criticism about why they can't do x,y and z when its within their job description / what is expected of mainstream and have all this funding etc etc
You will then get a statement with exactly what SEN officers, EP and outreach in a secret meeting that has already happened have agreed. They will probably tell you it will go to a panel who will rubber stamp the provision the SEN officer has already decided to award.
If school refuse to agree and say they cannot meet need even if all this provision is put in the statement, the LA will probably find another mainstream school weaker HT who will agree.
It really depends how much you trust the school to back you up under what will be extreme pressure (before tribunal our nursery staff were called in and subjected to a 2 hour barrage of questions criticism by a panel of 4 LA staff). Whether school will def appear as a strong witness for you at tribunal against the LA.
The alternative if you have doubts about school (or school agree to play along) would be to let them issue the statement, put in the extra support, put him back in mainstream and you (and hopefully school) then get together evidence that it is still failing (hopefully quickly)
Usually you have to prove even with all the top level support it will not work before you can win a more expensive placement.
Possibly a private EP coming in now would be able to say even with x,y and z that will not be enough. But then it is still your EP -v- their EP. But yes ideally you want the private EP to see the placement you are arguing against and the placement you want because it will look better at tribunal if your EP can talk authoritatively about the mainstream placement and why its not suitable.
If its SLT / OT that you need and mainstream can't provide there is a good chance just before tribunal or on the day the LA will suddenly offer loads of SLT / OT on top.
So tactically it may be better to put him back in and let it go wrong. Really sorry but that is the option which probably gives you the best chance of success and maybe the quickest route to what you want.
You have to balance the downside now against the risk you lose at tribunal in 8 months time because you have not tried this provision - are forced to try it - it fails - and takes you another year to get back to tribunal.
It really depends on how strong your evidence is so Fiona will def be able to advise.
