but I think the artacle is right - predominantly the ofsted reports aren't worth the paper they're written on.
A nursery fairly near here received a bad ofsted report a couple of years ago. It was part of a chain so the owners ploughed lots of money into it to get the ofsted report back up, and at the same time they closed one of the better nurseries in the area. As soon as ofsted had been back, the nursery went back down to its former standard of crap, but because the ofsted said it had improved, many parents put their children in there because of the closure of the sister nursery.
yThe conditions were awful.
the preschoolers were in a room up two flights of stairs with no access to outside, the menu claimed they were getting fresh ingredients when in actual fact they were getting things like spaghetti hoops three/four times a week, the manager's 9 yo daughter would come out of school and go into the baby room to play with the babies . But because the ofsted report says it's ok now they won't be back for another 4 years or so.
IMO ofsted should do surprise inspections - there shouldn't be any warning of it happening - an ofsted inspector should be able to walk in and say "I'm here to inspect your nursery", and if the nursery/childminder is up to scratch then that won't be an issue. And if the nursery/childminder gets a bad report it should be closed until it has proven to have put steps in place to rectify the problems.
