@Bernie12 I think you make a lot of good points, but I think we are having two different conversations.
My initial point was that the relationship between rigor and selectivity and scores is “somewhat” linear…I’m sure if we dissect the schools’ stats school by school, variable by variable, the graph would be all over the place when examined at very low levels…but pull up to 10,000 feet and I would still guess that “rigor” if it is something that can actually be measured, would track somewhat proportionally with selectivity and scores. So I agree the schools with closer average scores will have more gray areas between them.
I’m not sure I understand your point about the average grades in certain STEM sections that did not change…that kind of supports the point of the professor teaching to a new center, no?? And the shift in “center” might be so subtle that even the professors don’t realize it?
I just think overall the student community is going to drive rigor the most. So the best way to OVERALL determine how rigorous a school may be, IMO, is to try to get a feel for the types of students attending. Without first hand information, scores and to a certain extent, selectivity, might be the best way to determine that. It’s certainly the most, if not only, objective one.
You also raise the point of “academic quality” which is not necessarily the same as “rigor”. This is one of those gray areas, as in the example of Brown being less stressful. But that doesn’t mean a student at the low end of the applicant pool is going to have an easier time at Brown than say, Bucknell, where they would have been at the high end of the applicant pool.
As for Chicago, I have heard that they are doing what they can to drop the “Where the fun goes to die” reputation, so I’m not surprised that it hasn’t gotten more “rigorous” since it’s gone up in the rankings. But it already was rigorous. Their dean’s list is a 3.2. That’s a lot lower than some other schools.
I also think scores are going up across the board, especially at the top schools as applicants realize the bar keeps getting higher and higher and as their parents are more and more willing to pay for the tutoring they need to hit their scores.
It’s all such a game and we are searching for answers that may not exist. The best thing to do is to apply to a wide range of schools so that after April 1st you can go to the campuses and talk with students and professors, try to get a feel for the rigor, and find the best match for you.
