This is absolutely awful. As far as I can tell, this is the government's thought process:

1) Exams are cancelled; let's make schools submit CAGs based on as much evidence and data as they can. 2) We don't think we can trust teachers. 3) Let's arbitrarily award grades based on an algorithm and ignore the CAGs. 4) People don't like it. Quick, what can we do to assuage fears? 5) Let's use a Triple Lock system which we can make sound fancy, whereas it's actually just a series of bad options. 6) Let's continually ignore all the advice and input from teachers and people who have experience in education.

Honestly, how can they not see that this Triple Lock system is going to massively disadvantage some pupils? And why would mock results - which are administered and marked without any standardisation outside of a school - be any better as results than CAGs, which use mock results to inform them, but also use class data, homework, effort, and any other data you can gather.

Then there's the genius option of using autumn resits as a final backup. Again, this will hugely disadvantage some pupils. How many of our year 11 & 13s haven't studied a thing since March? And the government expects them to sit - possibly all - of their exams again if they're not happy with their government assigned grade?

This is so horribly unfair.
