No, I haven't done that. Don't know how to! I teach film, and often stats lump it in with Media.
My subject had a higher prior attainment This Year than last on average. I have the same CAGs as last year. The group size was identical! We had no group in 2018 but a huge cohort (32) in 2017. This underperforming year group skewed outcomes massively.
I think the class has to be 4 to be completely untouched.
Someone who has been through stuff with a fine tooth comb reckoned classes of about 8 to 12 were often the most affected. In a class of 8, one student is 12.5 % , so the exam board couldn't award my A and A * because their computer saw that as 25 % of the cohort. So , I got one A. And, yes statistically that us still 12.5% top grades, so on paper it sounds fine. But last year, we were on 25 % . It also has gone from 12.5 % D to E last year to 25 % this year. Never had that!! In theory, if they messed at the top end, they shouldn't by the same reasoning have allowed the percentage of Ds to go up so much.
I haven't read the A* to E pass rate anywhere?
Really cross with everything, even though the results weren't even dreadful.
Law took an absolute hammering in my school.
