An education system that always fails a set number of people, regarless of how well people do, is a bad system, however.
There will always be 25% in the bottom quartile, regardless of how well any students perform.
I think their point is that you could have people in the bottom quartile who learned what they are expected to, are capable, but are failed anyway because of how they compare to others.
(Assuming curved tests really work like that, never bothered reading the pretty long grading policies)
I’ve been graded on a curve, and I’ve done it myself a couple of times. IMO, it’s usually a sign of a bad class (too much material being crammed in) or a bad teacher (didn’t get the concepts across to the majority of the students).
That said, it’s usually done when it’s needed to prevent a significant portion of the class from failing. I remember a chem exam I took where a 16/100 was a C.
The basic idea is that grades are normally distributed (ie a bell curve) which allows you to find the average grade range and shift the letter grade (eg a C or C+). There’s some professors who take the idea too far and rather than working off of an actual normal distribution try to fit the procedure to a simply skewed distribution or use it to pull down an 85/100 to a C, but in my experience that’s the exception to the rule, especially in math/science courses.
Also, iirc this is a parody account.
