Other countries have managed it
To be fair other countries either ran some sort of exam or accepted that grades would be inflated. The grade inflation is not due to teacher favouritism or incompetence , it is because of well understood factors always present when teachers mark work not based on a specific assessments.and then compare those to exam based grades. It is like comparing apples and pears.
The major problem with this government is their inability to clearly face up to the consequences of decisions and to manage expectations about those decisions.
It was clear to anyone with half a brain from the moment exams were cancelled that we would have quite a lot of grade inflation. Deciding we wouldn't is like saying I can decide to eat 3,000 cal worth of cake for a week and lose weight. Well I can if I hobble the scales so it just looks like I have lost weight.
Other countries understood there would be grade inflation if they cancelled exams. It isn't the end of the world. For some young people it will give them a chance to show they can do it antway. Some will rise to the challenge, some won't. After this shitty year they ALL deserve that opportunity
Universities would have understood this and planned for this if it has been faced early. Instead they are left scrabbling at the last minute yet again to deal with an inevitable outcome because the government was too cowardly to buy the bullet early on and just say ' we are cancelling exams, we trust teachers to do a good job buy we also know that some grade inflation is inevitable'
