Colleges are the most data-driven business entities. They will figure out the degree of grade inflation per AP test, and will adjust their AP Credits table to raise the score required for the tests with material grade inflation. The question is, why do we need this extreme quantization of results? a scale of 1 to 5, seriously? An ACT score that is 1 to 36 with no fractions, seriously? Why don't you scale it out of 100 and let the students differentiate?
There were some ap exams I believe that have had their 5 rate lowered such as both AP Physics C exams and AP World, so would that really count as inflated?
I think AP grade inflation is more common than AP exam score inflation….. this is because a lot of teachers have the prerogative of passing their kids and/or inflating their grades in the AP class- many of the kids get As in the class but struggle to get 2 or 3 in the exam where scoring is more standardized and less prone to teacher bias. So for those kids who get Bs/Cs in the class because the teacher may be tougher but end up with 4/5 in the exam- it tells us that they have at least had some understanding or ? mastery of the subject
