Sorry, I should have said 'Not if everyone takes the same exam each year, not ones from different exam boards', although I thought that would be obvious!
It's not obvious because it's rubbish!
If you had a clue about examinations you'd know that different boards' syllabuses have different content
Even if they did, you seem to be expecting employers as well as colleges to look up the exam content for a given year, so they can make a judgment about the marking compared with other years.
That's ridiculous.
Colleges have to rely on the education authorities to produce a year-to-year-valid grading system
What evidence do you have that kids work harder?
And exams have simply changed. For example it's a lot easier/quicker to use a calculator than logarithm tables so there is indeed a lot more in, but more quality?
Then of course there is the internet and computer aided tools...
If you really think standards have gone up then you obviously haven't a clue about the basic mental arithmetic and spelling skills of your average student!
I've looked at exam papers in subjects which I know. And watched how much work kids do.
Yes exams have changed but if you have to cite calculators and log tables you're obviously struggling, that's ancient history.
Mental arithmetic isn't measured in an exam. "Showing your working" has always been the norm.
The internet isn't used in an exam.
Spelling features somewhat in relevant subjects, much as it always did.
In 4 stem subjects, difficulty dropped, when they decided maths had to come out, then went up. The A levels are harder now than they were when I did mine. Check 15-20 years ago, they were much easier.
A specific example - I'm sure you're familiar with the equations :
s = ut + 1/2(at^2), v^2 = u^2 + 2 as, v = u + at.
Those used to be in A level.
GCSEs were easier than O levels.
These equations weren't in O levels, but
Now they're in GCSEs.
Phys Chem Bio used to be separate only, now they've been combined into a double because some kids couldn't hack them separately. The breadth though, even in the combined, is large.
My interest has been piqued for a while because I happen to know some teachers who rant on about it. I know one fewer now - Nige just died of covid.
