UChicago over Stanford?

UChicago is higher ranked than Stanford (US News) because UChicago is better at generating the right stats for the methodology. You could call it gaming the system, but that’s a little unfair since it’s not all deliberate. According to Parchment.com’s statistics, about one in three students choose UChicago over Stanford, if admitted to both.

Here’s a step by step walkthrough of the indicators that go into the ranking:

Graduation and retention rates

UChicago has a graduation rate of 86%. Stanford, only 75%. The difference is cultural. Stanford is a highly entrepreneurial and career-oriented school. Many people drop out of Stanford to pursue their business ideas or do other things.

Meanwhile, UChicago is known for sending a lot of people to grad school. If you’re trying to get into a good grad school, the last thing you want to do is drop out of undergrad. So the studious culture at UChicago lends itself to a higher graduation and retention rate.

Undergraduate academic reputation

This seems like a very fuzzy section. This section is supposed to account for “intangibles” via an opinion survey of various academics and high school counsellors.

I don’t have the raw scores to compare Chicago and Stanford, but I suspect UChicago would come out on top. Stanford has fantastic academics, no doubt. But historically UChicago has a very close knit and rosy relationship with academia. Everything from the Common Core curriculum to the anti-grade inflation teaching philosophy adds a subtle shade of approval in the ivory tower.

So the fact that academics were surveyed, rather than employers or the general population, gives UChicago an edge.

Another thing that caught my eye in the methodology was this bit:

To reduce the impact of strategic voting by respondents, U.S. News eliminated the two highest and two lowest scores each school received before calculating the average score.

I’m not sure how sound this methodology is. First of all, people could strategically rank their first-place college as third, now that this methodology is public. And second, this methodology benefits a school that comes in consistently third, rather than first or second. Here we can only speculate, but it wouldn’t surprise me if UChicago benefitted from this bit of the methodology as well.

Faculty resources

Class size is 40% of this category. UChicago wins out on class size—78% of classes at U of C have <20 students, versus 71% at Stanford. UChicago places great emphasis on making classes smaller, and interactions with the professor more personal. I applaud this approach and believe that Chicago’s win here is well deserved.

Another 35% of this category is average faculty salary, adjusted by cost of living. There are two key parts here.

  1. Using average salary as opposed to median salary means that a college is higher ranked if its distribution is positively skewed, i.e. the professors at the very top make a lot of money. I don’t know about Stanford, but I do know that UChicago keeps several high profile professors on retainer by offering them huge sums of money. This drives up the average, even though the median would not be as affected. However this is just speculation.
  2. Cost of living is the big one. Living in Chicago isn’t cheap, but it’s nothing compared to Boston or the Bay Area. That fact alone would greatly skew Chicago’s faculty salaries to appear higher.

Is better paid faculty better faculty? I have no idea.

U.S. News also weighs the proportion of professors with the highest degree in their fields (15 percent)

As I said before, UChicago is very academically inclined. It wouldn’t surprise me if the professors there were higher up the ivory tower, especially compared to a school like Stanford which hires from more diverse backgrounds (possibly with fewer years of formal education).

Student selectivity

This section is worth less than the previous ones. It looks at SAT/ACT, which UChicago wins out on. I suspect this has to do with athletics. No offense to athletes, but their scores just aren’t as high.

Also considered are what percent of the student body was top 10% of their high school class, which is probably subject to the same effect as SAT score. Athletes would drive down Stanford’s numbers, plus UChicago’s reputation as a mega-brain school doesn’t help.

However, Stanford has a lower acceptance rate than UChicago. A rare win for Stanford in the rankings.

Other categories

Per-student spending, I’m sure both schools spend a lot. I can’t seem to find hard numbers.

“Graduation rate performance”, basically US News runs a regression and gets an expected graduation rate. UChicago’s graduation rate is probably higher than expected, due to the cultural emphasis on post-college education, so this nets U of C some more points.

And alumni giving. Personally after our family has paid tuition I feel like we’ve given enough, but for some reason people feel compelled to give even more. I don’t have access to the full data but at 5% of the total ranking this section isn’t that huge of a factor.

I think you understand this part wrong. It means among all the score ONE school received (from all the surveyees), the highest two and the lowest two are removed before the data is averaged.

Say you have 7 people give scores to schools.

If Standard got 5,6,7,8,8,9,9, her average would be (7+8+8)/3=7.67.

This is a widely used scoring system, namely almost all the scoring Olympic sports, such as diving and gymnastics.

You can’t game it by give your first-place school as third… it’s not removing the highest two of a certain surveyee.

Interesting idea, but why remove only the top two scores? Wouldn’t there be far more than, say, 7 people who are scoring the schools?
