I do have to say (politely) that none of the HE council workers I've interacted with are in any way qualified to judge whether or not the education I provide is "suitable". All my letters and emails from them are absolutely riddled with the most basic grammatical errors. Clearly school didn't do them much good, from an educational perspective at least.
I think the national curriculum is dreadful, but I do keep my eye on where my son "should be", in case he ever goes to school. He's lightyears ahead in all areas.
Of course when you say your child is ahead academically, you immediately get "well I bet he's behind socially", as if people have such a narrow mind that they can't possibly imagine any other form of socialising than one gained from being sat at a desk 5 hours a day.
If I sound fed up, it's because I am - fed up of questioning by council bods who can't even write a coherent sentence, and of people generally being incredibly rude and assuming we are religious nutjobs, hippie off gridders or anti social weirdos.
I still don't object, in principle, to a register. I've got a good relationship with our local LA, despite often feeling resentful of them!
