A 2021 newsletter discussed mark inflation in India. The newsletter has some shocking statistics; how average marks are often 100% now. However, mark inflation is not new. Using our own data from the 1960's and 70's, the average in a typical Ontario high school with a post-secondary trajectory for its students was in the 68-72% range and only 4% of the students had a graduating average of 80+. Compare this to what happens today. The averages of the same schools (comparing apples to apples) are now all 95+. Here's a new flash, the human brain has not evolved, nor improved that much.
Mark inflation has also happened at the university level. In the 1970's, the average in a course was around 68-72 and only around 10-15% of the students could expect to get 80+. Compare this to the numbers you are familar with in today's situation.
A key point to consider is the difference between the high school inflation and higher education inflation. Both started out about the same in the 60's, but the slope is different and this creates an ever increasing gap in expectations. There was a gap in the late 80's and it was a little shock to the students to find a few marks being different. The gap is now quite large and it can be quite difficult for both instructors and students to deal with.
The key problem with mark inflation is that it comes down to poor standard setting and it arises from different sources - pressure from students, parents, instructors, and institutions. There are many forces at work that initiate, facilitiate, and sustain mark inflate. Some of the influences are outside of an instructor's control. However not all are. For example, we dislike those who take the easy road and never really set a standard for the student to try and achieve - somewhere above their level when entering the course. Everyone gets an A ultimately cheats students of the experience of being given a challenge and then discovering that they are able to reach it. This has to be balanced with those instructors, we also dislike, who set the impossible standard because they want to make sure that the students have it rough; they are equally cheating students of the discovery that rising to a challenge brings because they have done nothing to prepare the student for the challenge but have rather set them up to fail.
