@bambi0611, I specifically didn’t use inputs as a measurement because they can be gamed. For instance, a college that simply admitted the applicants with the highest test scores would shoot up that ranking, but the applicants with the highest test scores may not be the ones with highest potential or contribute the most in class/to the school/to society. Furthermore, inputs tells you nothing about how good a job a school does in actually educating its student body.
That’s why I based my ranking solely on outputs (alumni achievements). Obviously, there is a strong correlation between inputs and outputs, and I’d rather have a smarter student body than a dumber student body, but I think that how well a school’s alumni do tells you more about how good a school is than how high an SAT score their students got in HS.
