3rd year university, all engineering students are told their grades are going to be "normalized" with those of other faculties such as Science, Computing Science, Physics, Math etc.
We were all "huh?"
It turns out engineering grades for the same courses were held down, much lower which was a problem for students transferring between faculties and of course... weak students needed a better chance at passing in engineering. Instead of weeding them out.
Made me laugh because 1st year engineering was brutal for marks, they trashed students on purpose to get them to drop out - you don't get a refund on tuition then. The uni made good money off this and enrollment numbers looked good for the government.
So all of our grades took a jump up, I estimate +20% or ~1/9.0 scale
That was the day I realized student achievement and merit is arbitrary. Any problems you can blame the students for being lazy, low achievers. Set the bar wherever you like, but the Bell Curve can still be hacked and warped as needed.
In academia there are many "weak" profs that used a garbage thesis for their PhD. Some were pretty dumb but got their post-doc.
Merit? It could not be measured. Even volume, # of papers published actually means nothing. The content of the papers was most important but nobody ranks that, including the funding and grant agencies- that bring money into a university. An ounce of image is worth a pound of performance.
