I don't know the full background to your DS's difficulties - just what you've posted on this thread.
I fully appreciate the frustration in trying to get the right sort of help for a child via the 'established' channels. God knows I was faced with that too.
But each blocker needs to be tackled and not seen as a brick wall.
If a Paed will not dx then you have a legal right to referral to an alternative consultant. I exercised that right.
If the alternative consulatnt is still scratching his head you can ask for a tertiary referral. Many on here have done that.
If you want to bypass the NHS and can afford to do so then go for a private dx. I did that.
If the LA Ed Pysch is crap. Look for a private Ed Pysch. You did that and didn't rate the report you received very highly. However you also stated that the report recommended 1:1 support. You could use that report to support your assertion that your child does need 1:1. You start doing that by applying for a statutoty assessment yourself, describing your child's longterm difficulties and enclosing the private report that supports 1:1. When the LA fails to act you utilise the SENDIST process to force them to recognise your son's difficulties. You use every piece of ammo available to you to force your point of view.
If the SENCO is rubbish and the Head Teacher is in denial then you really need to seriously consider changing schools. If you are going down the SA route then you don't need the support of the SENCO and Head - you counter their views with your private assessments.
I expect that by now you're reading this and thinking - yeah, yeah, simplistic advice, been there done that and don't have the T shirt.
It's easy to get so totally embroiled in the difficulties and frustrations that you don't see the bigger picture. What has been tried in the past and has not worked, might, with a fresh approach and renewed energy, it might just work the second time around.
You shouldn't have all your eggs in one basket via an alternative therapy approach. If alternative therapy works for you that's fine, but you also need to engage with the formal support system, jump through their silly hoops and force them to recognise that your child does have very debiliatating difficulties that the formal SEN support framework must address.
Again, I realise that you can pick as many holes in what I've written as you want to. I don't come on this board to slag people off. I come on this board as the mother of a much older child than most on here to share my experiences and offer my advice. If you knew the particulars of my son's case and the unbelievably bad way in which his difficulties were handled by GP, SALT, Ed Pysch, LA, School Nurse, CAMHS, EOTAS, etc - the same people that you too say were useless, you would think I had written a work of fiction. But I didn't let these people become blockers to getting him support. I worked round them, and with them when I had to.
I admit I was very annoyed to see TH recommended to a first time poster. By all means try alternative therapy but not as a first resort.
If soemone came on a breast cancer thread who had no knowledge of the condition she had been diagnosed with I think you'd be annoyed to see alternative therapies backed up by claims that they will cure her suggested, rather than the traditional chemo, meds, etc. How would she be able to differentiate?
So that's my explanation and that's my response to your question 'What should I do?'.
