Chequers, good point that about Ofsted also inspecting schools. Which is a big part of what they do. The Ofsted stamp of approval is not necessarily goldplating for highly rated schools either.
If the programme were about poorly performing schools (as opposed to nurseries), would the same parents whose dcs go to school then pull all of their children out of school, in the same way some posters seem to be urging parents who use nurseries to do, based on the programme?
I suspect not. If you and dcs are happy with your school/nursery, there is no reason to change. The programme makes not one iota of difference. I suspect the programme is only interesting because it is another stick to beat working parents with, after all it would be working parents in the main who rely on nurseries and cms.
soapbox, in the world of nurseries, you are right, parents don't and will not put up with substandard care. The best short term solution is to vote with your feet. I know if I could not find a nursery that dd liked, I would have investigated nannies and cms. It is not denial that my nursery is good when in fact it is shit . It is market forces at its best.
