How do Hogwarts' muggle-borns drop off the radar?

If my sister took her kids out of school, she'd have to inform 
certain authorities, and demonstrate that they are receiving an 
education at either another school, or private tutorship. They 
would have to have exams and reach formal levels to show that 
everything is going well.
So when, for example, the Potters and the Grangers send their 
Harry and Hermione off to Hogwarts, what do they tell the local 
authorities? Suddenly the kids aren't at school anywhere, and 
there's no record any longer of either of them getting an 
education. I assume the parents or guardians can still draw 
child benefit payments, so either England is an easy country to 
'lose' your kids, or it's something else JKR overlooked. Or I did.

I was just wondering about it, probably because I'm going 
through an insomnia phase, and these things become important 
at 3 in the morning!
