Yes, historically in lots of schools, low percentages achieve top grades. In others, vast numbers achieve the very top grades. The national figures for %s at each grade hide vast differences between schools.
It’s not discrimination against certain schools. It’s the reality of the cohort in terms of its ability and background situation, along with the ability of the school to get grades out of its given cohort.
And I agree that some sharp elbowed people can only accept either top grades for all or top grades for their kids. Accepting that the vast majority won’t be getting A*-B and that one’s own child is probably within that vast majority, just seems impossible for lots of people. Instead there must be a discrimination or an error, not just the case that this is what this child was going to get. Sounds harsh, but there’s something in it.
And yes, this year group have had a shit experience and it’s been horrible and the continued lack of clarity about appeals makes it worse. But a shot situation cannot mean all children must be given the inflated ucas grades that were used or inflated teacher grades which were significantly higher than usual.
The system does need to be fair and seems to have some problems, but in the end, similar percentages should get the top grades and the pandemic can’t be used to say everyone must have high grades - or they are meaningless for all too.
