Dysgraphia

[Yope]

How do you get an assessment for dysgraphia? I have no clue where to start.
My DS is 15.
He holds a pen in a most unusual way. I can't even understand how he manages to write whilst holding it the way he does. His fingers wrap round the pen in a sort of claw grip and his thumb.wraps right round over the top of his fingers. How he manages to write legibly like this I don't know. He presses overly hard on to the paper with his pen. He says his hand and wrist start hurting quite quickly when writing.
He holds his cutlery wrong. He doesn't hold it correctly in his grip despite a lifetime of me correcting him. He also holds his knife and fork in the wrong hands, the wrong way round, which is bizarre. He's right handed, but holds his fork in his right hand and knife in his left hand. When I correct him and tell him to swap his knife and fork round, and teach him how to properly hold his cutlery, he can't do it and gets instantly stressed.
Is this Dysgraphia? I've only just heard of this. Until now I thought he was just unable to be taught how to hold pens and cutlery.
Now I wonder if there's actually a cause?
I know this is a bit unusual but does anyone else have any experience?
How do you get teenagers assessed?
Thank you!

Find an educational psychologist , ours tested for dyslexia , processing and dysgraphia.
we had to go private , worth it if you can afford

How much did you pay, and where do I find one?
A quick google for Ed psych in my area came up with nothing.

My child used to do that, DC is dyslexic. I agree with the previous poster.

You might have to travel quite far , we did. I paid about £700 but the wait for a school referral can be years in our area.
there is a Facebook page Dysgraphia UK that has lots of recommendations and advice so might be worth joining and also asking there.

I've no idea about dysgraphia assessments, but I'm also right-handed but eat like I'm left-handed. It's hard work trying to eat with cutlery in the other hands. In my case, it might be something to do with genetics, as my mother is also right-handed but does some jobs as if she's left-handed. We're not dyslexic or anything, as far as we know.

Schools would normally try to teach the "correct" pencil grip, but some children simply don't grasp it. I remember one in a class that I worked in, and it was suspected that his extraordinary pencil grip was possibly related to dyslexia and dysgraphia, as his older sibling was the same, but with a diagnosis.

Or it could be dyspraxia (sometimes called DCD now) if it affects more than handwriting. Co-ordination and executive functioning issues are key aspects (in the lowest 5 percentiles of the population).

My daughter saw an OT for 6 sessions who provisionally diagnosed dyspraxia, and then a paediatrician who ruled out any other cause of her issues, to confirm the diagnosis.
