I suspect this would have influenced preference orders on the CAF form if this OFSTED result had been announced a few weeks earlier!
They couldn't have announced it a couple of weeks earlier as they hadn't actually had the OFSTED at that point (or at least, were in the middle of it). Do parents really choose a school purely on the strength of an OFSTED?
When Archway was put into Special Measures 3 years ago, there was a sudden spate of parents wanting to transfer their children to Marling & Stroud High from there - that was despite there being no problems with the teaching & progress of brighter children at Archway found in the OFSTED. I wonder if those parents considered moving their children back when Archway got a 'Good' 5 weeks ago?
