Now that the Scottish exam results have reverted back to those based on teacher predictions, students have done MUCH better than previous years, around 10-12% improvement, or over a grade compared to previous years.
To put this in a chart – here’s what it looks like: The middle column is what the results were last year, the last column is what they now are, with the government’s U turn.
|2016-19 Ave||2020 SQA moderated||2020 teacher predictions|
To display this graphically – we’ve leapt from blue to yellow, while even with moderation (red) that kind of increase is just about feasible, even if unlikely.
It is highly unlikely that this year’s students on average would have achieved 10-12 % points higher than the previous year’s students, had they sat their exams, had there been no disruption.
Had they sat the exams, they would have been moderated by the exam boards so that the pass rate and A* rate was broadly in line with previous years, and then the spread of results would have probably also been broadly similar.
What’s happened instead this year is that we now have results based on teacher predictions, rather than ‘pure moderation’ by the exam boards, which broadly keeps things in line year on year.
In case you don’t know, what the exam moderating authorities do with actual exam results, is they look at the raw marks, and then tweak the fail/ pass and A* raw mark boundaries so that there’s a similar percentage passing and achieving high grades every year, but now they’ve had that power stripped from them.
Now the grades are based purely on teacher predictions and teachers always over-predict, it doesn’t take much explaining to figure out why – because of the competitive education system, and it’s one of the few rules you can bend as a teacher, so nearly every teacher does it, because they know every other teacher does it!
TBH I don’t think either system is that valid. You’ve seen the results year on year, it’s highly unlikely that there’s going to be a gradual trend upwards, without there ever being a single ‘spike year’ – but that’s what you get when exam moderating authorities ‘control’ the grades every year – a gradual increase gives the impression of credibility.
Teacher predictions might well have more credibility, because they actually know the students, but there is a problem of reliability when, for just one year, this year, 2020, you allow exam results to be determined by teachers, and then you get a massive spike compared to previous years.
Students who sat exams in 2017 to 2019 should be complaining
Students from the last three years are the one’s who are being harmed by this unjust political interference – not only do they now have a worse track record of exam results compared to this year’s students, these are the students who are now graduating into a world of contracted employment, so they’re going to have ‘worse’ results, and a longer period of unemployment on their CVs.
This year’s students by contrast, if they’re going on to 2-5 years of FE/ HE, the chances are the economy will be recovering by the time they graduate, so they’ll have a better education record and less of a track history of unemployment.
