No, not permanently. But a good 4-6 weeks is certainly not unheard of. Ofsted has been truy hrrible to my childminder. It has been nothing short of a whitch hunt to find something wrong with her after every single parent whose children she cared for wrote Ofsted VERY strong letters supporting the childminder and condemning their decisions to suspend her.
This happened before Christmas and, as you can tell, I am still absolutely livid. I used to think Ofsted had their place, and now think whatever portion of government funding they get would be better spend elsewhere.
I hate them for they did to my lovely childminder. Really really cannot understand what value they bring to the system.
Your sister could, of course, work as a nanny if they shut her down.
Although, when my (truly fabulous!) childminder was shut down my son (almost 2 at the time) was completely extracted from all of his friends because Ofsted tol her she could not pick him up at school and drive him to the other childminder where all of the other children went until her registration was reinstated. She doesn't even NEED to be registered to give my son a ride somewhere else for 10 minutes. Yet, they felt it was their place to ensure my son was completely left out of the arrangement. Putting the welfare of firdren first MY FUCKING ARSE!!!!
I am still slightly annoyed with them. Can you tell?
