But first, the context: 'The govt had its own political agenda to keep grade inflation low. And they don't listen to experts. There was no system-level thinking at all. Ofqual was boxed into corner from moment Gavin Williamson & Nick Gibb decided against teacher-assessed grades'
'Ofqual had no choice but to come up with a methodology because Gavin Williamson couldn't stomach centre assessed grades. Really not Ofqual's fault. Apart from should have come up with a better appeals system. And they still need to for the kids who need to appeal teacher grades'
'But given Williamson's decision, they needed statistical model. So they collaborated with the exam boards to come up with different models. And this was the one that came out best in tests. Done in collaboration with Cambridge Assessment'
'Gavin Williamson & Nick Gibb both briefed, both signed off on it. They knew in advance. This is down to them. How much of this could have been predicted? All of it. It's flabbergasting. And now there's a university crisis alongside a Covid crisis & a health & safety crisis'
