An article on Inside Higher Ed relates a study that shows Republican professors (both of them) grade in a less egalitarian manner than Democratic professors. Republican professors awarded a wider range of marks, giving more high grades and more low grades. Democratic professors tended to give fewer “extreme” grades.
It would make sense that Republicans would be more merit based in their grading, something that keeps with their philosophy (greater tolerance for difference in outcomes). The study points out that Black students tend to fare worse under Republican than Democratic grading, but also states that they tend to receive lower scores under both regimes. I presume they are leaving the charge of racism to others.
This probably should not be a shock, but interesting in its own way. I guess you should hope you have a Republican (assuming you can find one) for subjects you are good in, and a Democrat for those you are not good in.
I am just surprised they could find enough Republican professors from which to draw any data.
From the linked article:
On grade distribution, Republicans were more likely to give very high and very low grades. Among grades given by Republicans, 6.2 percent were C- or lower, compared to only 4.0 percent of the Democratic grades. But Republicans were also more likely to give out A+ grades (8 percent of their grades, compared to only 3.5 percent from Democrats).
With regard to race of students, the study found that black students received lower grades, on average, than did white students whether classes were taught by Democrats or Republicans. In courses with Democratic professors, the gap was 0.27 on a grade point average. In Republican-led classrooms, the gap was 0.42.
