Comments from teachers are being quoted by the Guardian, and this struck me:
The most important thing to note is that we already factored in those inconsistencies with regards to mocks, and then used other data such as assessment, coursework (which otherwise would be completely ignored this year), AS outcomes and a comparison against historic data to give the centre assessed grade. The allocation of centre assessed grades took weeks of work
That's what so infuriating about the latest govt announcement. Teachers came up with CAGs using mock results if available, but adjusted to allow for all the other knowledge they had about students' performance. Now the government are saying "we're not going to give you your CAG (unlike Scotland) but you can have your mock whatever that is and regardless of the context".
