child having a bad time in school
mum thinks it is the school's fault - that her child is fine, but that the school are failing to meet her needs
school say that they think the child has undiagnosed special needs of some kind
EP has seen child in classroom and has already come to the conclusion that yes, the child has SEN of some kind.
So EP is referring on to a paed who will be able to make the kind of diagnosis from which, if school and EP are right in their instinct, extra ££ and help for the child in school will flow.
I've got to say, as an educational dissident myself, I completely see the school's POV here, even the welfare part of it. They see the child is having a horrible time, but they do not have the resources to address it without the funding that would follow some medical condition that would explain why the child is having such a horrible time. If the mother is trying to block this bid for extra help for the child, then it is indeed the mother who is responsible for the continuation of the horrible time at school.
Either
a) go see the paed. Be ready to hear that the child is not neuro-typical and, with that extra help, help them to make a go of it in the school environment
OR
b) withdraw them from school. Go to see the paed. Explain that you think that, whether or not the child is neurotypical, school was a major trigger for them, so that actually diagnosis is not really relevant or welcome at this point, since you will just be working hard to meet the child's individual needs with a home-based education.
But yes, you go and see the paed. You do not want social services being called, which is what the school and EP would (justifiably from their POV) be likely to do next.
Sorry. I know this is not what you want to hear.
