HiOP,
I have read through some of your posts so forgive me if there are things missed. I work in a community child development team, I complete ASD and other developmental assessments. I am a psychologist, paediatricians where I am are not involved unless child is under 5yo.
What you describe sounds like a complex profile. You have the impact of a medical dx to consider, and describe some things consistent with ASD and quite a lot of things consistent with dyspraxia and/or dyslexia. When you eventually get to have an assessment this will be done comprehensively. As I’m sure you’ve been told, your EHCP is supposed to be needs led so no dx should make any difference (although in reality I know it does matter).
However, I wonder whether school may be able to refer using their school hours for an assessment with their educational psychologist? This would be what we would suggest as a next step from within my assessment service (NHS, although of course there are huge discrepancies between services).
the reason I say this is that I would assess for neurodiversity (ASD/ADHD) and /or learning disability (IQ less than 70). I don’t think you child has s learning disability from your description. Learning difficulties (dyslexia/dyspraxia etc) are classed as different to learning disability (in the NHS) and are assessed by Educational psychologists , who work within schools and are generally employed by the local authority (separate to nhs health services). Your school would refer for that assessment, it’s unlikely your paediatrician would suggest that. In my team we would be asking for those assessments to be completed before moving into more intensive assessment pathways for ASD, especially given the health picture.
Another consideration is that you can now ask to be referred to a different nhs borough based on the ‘right to choose’ pathway, your GP should tell you where has the shortest waiting list and you can ask to be transferred there. They need to be able to justify using a good reason why they can’t do that if they say no.
anyway, sorry you may have already been through all of this before but thought I would just chip in incase there’s anything that would be useful to you.
Good luck OP!
