As a teacher, who worked with dyslexic and dyspraxic children, I would suggest seeking a professional evaluation of your granddaughter's needs, before she is much older. The earlier the intervention, the better. I know in these days of cutbacks, it's difficult to get help, but trust your instincts and persist until someone listens.
My own school was very proactive and as soon as we realised there was a difficulty, we investigated. We were known as a "Dyslexia friendly school".
A number of staff had additional post grad qualifications in supporting pupils with dyslexia, because we wanted to provide the best support possible for all of our pupils.
Speculating on what is wrong with her isn't really helping.
I'm surprised the school haven't picked up on it. Her parents could ask initially for an appointment with the school, just to voice concerns and ask for advice. Then take it from there.
To my absolute shame, my own daughter wasn't diagnosed until she was in high school, and to this day, she still talks about how "stupid" she felt. She had a huge vocabulary and was really good at hiding the fact that she couldn't spell. As with every condition, there are varying degrees.
It was only when I started post graduate study on special educational needs, that I realised what was wrong.
I did have to fight her corner to get help. It paid off, because when she went to university, she was allowed extra time in exams, anonymous marking and tutors were aware that she was dyslexic.
It is really hard not to become frustrated, for both the child and family. Self esteem can take a battering when something like this happens.
I hope things improve for all of you. There is no magic cure, but there is lots of good advice and support out there.
Someone needs to go back to Junior School himself.
Things that (sometimes unreasonably) get on your nerves...hopefully lighthearted
