The article in question is 'hidden' behind the Times 'paywall', however courtesy of Politics Home comes this snippet:
"The chair of Ofsted has argued in an interview with the Sunday Times that state schools need bad teachers to help children. "If every primary school has one pretty naff teacher, this helps kids realise that even if you know the quality of authority is not good, you have to learn how to play it” the schools inspector said."
No only is the chair of Ofsted ignorant of the fact that humans have children and that it is goats that have kids, she is apparently prepared to condone schools having bad staff.
Supposedly the lack of knowledge about who has what offspring can be put down to the fact she may be a dumb blonde (with a cleavage)?
