Grade inflation is up to the instructor. I know of no one who got complaints with grades so long as the professor clearly explained what students would be graded on and precisely how grades would be calculated. Occasionally, I would have some student pop in and tell me that they needed an A in my course to do this or that. I would tell them to bring in all their tests and I would have them add up everything and determine four grades: class participation, assignments, tests and the final. Then add those four and divide by four. I would ask them what did they get, and if they said 88.7, I would say that they needed an 89.5 to round up to a 90, or A.
As a rule that settled the issue. On the syllabus, I stated "I do not give 'extra credit' work." In HS, teachers would assign some report or something,and they would download stuff off the Internet and stick their name on it. That was extra credit.
I never had the grade dispute committee recommend that I ever change a grade, so they put me on the committee for eleven years. About a quarter of the professors that had disputed grades were very vague about how students were graded. In such cases, I and a couple other professors had some stuff drawn up as recommendations. Usually they developed less subjective and vague systems.
We had a couple of professors who gave students nothing but A's and B's. No one ever complained about their grades, so we could do nothing about it.
