I think I understand this. Probably. Grades comparison longitudinally are not the ‘real measure’ of actual attainment over time. Comparative judgement is a much more precise tool. Thank you.

Great post Daisy, now let me play Devil Advocate for a moment. It might be tricky to compare and draw conclusions as you’ve done here. But can we conclude that student achievement has declined / improved based on standardized assessment like PISA? Can we also go a bit on a limb and determine that at least 40-60 years ago, the content on exams was very different because a larger cohort quit school at a younger age to work and provide for their families? In Canada this was very prevalent. My grandparents and father in law all quit school at 12 or 14 because their families needed the money. Yet when it came to maths, nobody was smarter than my Grandfather.

Yes, I think you are absolutely right about the content changing because more students stay on at school. I've got some more on this coming up next week!
