He’s a nice story about a young girl who passed her driving test – after being told she’d never even pass her theory test.
However, the story makes me angry for a number of reasons. First of all, dyslexia is absolutely no bar whatsoever to either passing 
the theory test or to being a safe driver once you have. At worst, it is an obstacle which has to be overcome (it’s pretty obvious that difficulty in reading or comprehending words is going to be an issue, but it doesn’t have to be a terminal one).
Dyscalculia isn’t something I have any direct experience of as far as I am aware. I have quite a bit of experience teaching dyslexic pupils, but for all practical purposes dyscalculia is simply “dyslexia with numbers instead of words”. Apparently, about half of all dyslexics are dyscalculic as well, although dyscalculia can be manifest by itself, so I have probably experienced it without realising.
I find that a significant number of my pupils either have dyslexia, or have been tested for it for specific reasons while they’ve been at school. Some are only “mildly” dyslexic, whereas one or two have been severely so. I always point out that many famous – and very successful – people have been dyslexic, and it didn’t stop them. My favourite one – though not many pupils have heard of her these days – is the case of Susan Hampshire, who was a famous actress when I was growing up.
So it is both surprising and very frightening that in the 21st century someone like Abigail Elstone should have apparently been written-off so early in her life (when she was seven) by the system.
