The new Wallington headmistress is more than just a name. She came from Nonsuch and is apparently super dupa. It wouldn't surprise me if Wallington becomes the new Nonsuch in a few years time.
Nonsuch on the other hand has the prestige. The problem is, since the previous head's departure, it is seen as a headless chicken as demonstrated by the re-sit of the NVR test for one group of girls fiasco.
It is true that Nonsuch, at the moment, does not have a permanent head. But the resit of NVR has nothing to do with that. In one of the rooms (just one) the invigilators did not allow time for the practice questions and children probably lost about one to two minutes per section. It was the fault of one invigilator in one of the rooms and it goes to the credit of the Nonsuch school that they immediately admitted the mistake and as fairly as possible, went about correcting it.
The new Wallington Girls head was Dy Head at Nonsuch. Before that she was at a boy's grammar school, probably Wilson's. I am told that at both places she did not stay long. I hope that she stays long enough at Wallington Girls and meet the aspirations of the parents and students there.
By the way, the sudden departure of Nonsuch Head teacher is still a mystery.
