As Saracen says any forth coming changes (which may be proposed if we get a Labour Government next) will not be about what you have done in the past-they will be interested in what you are doing at the time.
She doesn't have to worry about any of that now, and if changes are planned, we'll get warning and spread the news quickly-we always do!

I'm wondering if I have misunderstood somehow?
There is no reason to record progress, or make the child write anything if as an unschooled child if he doesn't wish to.
What is the Grandmother right about?
I do agree with Saracen and Madwoman, I think the issue is with helping your mother 'deschool', see the education she is so amply helping to provide and to persuade her to do things differently.
The fact that your lad is already being put off, demonstrates to my mind, a need that requires addressing between you-and him.
I home educated three dyslexics-all the way through their teens, until they chose to go to college and then university level, where they have each done very well indeed, FAR exceeding what was predicted for them by the schools they left.
We didn't do any formal work at all. None.
When the children were ready and needed to, they started writing-even the most severely dyslexic one...
Forcing them to do so, or to record their learning in any way, before they are ready would have just put them off more and more.
What would have been the point in that?
