The study being referenced compares college exit exams as well as mean salaries. They found that the exit exams were not significantly different between people who went to elite vs non elite colleges. This doesn’t prove but might suggest that a better education is not what explains the higher salaries.
There ain't no such thing as standardized exit exams for colleges - especially for the elite rung of the colleges. My college department's professors set their exam papers as did every other faculty in similar colleges - so it's really puzzling what this article is arguing.
Lower rung universities do have papers set by the university for all colleges affiliated with that university but again every university sets their own exams.
There are also entrance exams for MBA schools which are entire different beast and not really connected to what you study in Bachelor's

How can you have a common exit exam for people who have studied different degrees? No two degrees cover the same content.
Is it covering baseline content that you could expect anyone to know no matter what degree they did... well then I guess that explains why everyone would get the same score!
