@AlbionGirl I am grateful for that, though I do not know if that helps the Department of Education scorecard system that is linked to at the start of this thread.
@DiscreteAlgorith
If you search the website that I linked to you’ll find much more information than the Dept. of Education scorecard provides. Your community college is included in the data.
Higher averages tend to be associated with a large percentage of engineering majors, rather than STEM majors. Biology is a STEM field, but its graduates tend to have lower pay levels at graduation. Note that liberal arts includes science and math (basically all of STEM other than engineering and the less common engineering technology).
Higher averages can also be found at schools where elitist employers recruit, often without being too picky about one’s major.
Of course, a likely reason for higher pay levels for most engineering majors is that weaker (aspiring) engineers tend to be “weeded out” in school, while weaker practitioners of other subjects can often graduate but are “weeded out” in the job market. The “weeded out” people do find jobs, of course, but the jobs may be neither as well paying nor in their subject of passion or highest interest. But then the weaker aspiring engineers are no longer associated with engineering majors at graduation, while the weaker aspiring biologists and historians are more likely to graduate in their majors.
Academic seriousness of a given major at a particular school is not necessarily correlated to the major-specific job market for that major. Indeed, economics and finance majors tend to do well in the job markets, even though they are not necessarily considered highly difficult majors (and if you think of math as a qualifier for difficulty, only at a relatively small number of schools are economics majors highly math intensive).
The likely answer is that:
a. For employment that is major-specific, the differences in pay rates between schools tend to be relatively small, and may be more due to individual strength of the student/graduate in the subject and the region one is located in.
b. For employment in some fields (e.g. consulting, investment banking, perhaps unnamed multinational companies in some unnamed industries referred to by some posters), recruiting is school-elitist (basically emphasizing one’s high school achievement of getting into a super-selective school and getting a high SAT score), but one’s major is less important (though the hiring process has additional testing and screening for various generally applicable skills).
Of course, there can be exceptions.
If the Yale graduate (of any major) goes into consulting or investment banking, s/he will probably make more money than almost all state university graduates (of any major). But not everyone is interested in those jobs. Indeed, a Yale engineering graduate who wants to work in engineering (as opposed to consulting or banking) may not derive any recruiting benefit from being at Yale versus many state universities.
However, it does not appear to be generally true that most H/SS majors outperform engineering majors in pay in middle to late career. Some people may be looking at CEOs of big companies and such as examples, but few people from any college major become CEOs of big companies. On the other hand, the top performers from any college major tend to do well. Of course, being a top performer in the job market requires other skills in addition to the ones learned in schools (regardless of major).
http://online.wsj.com/public/resources/documents/info-Degrees_that_Pay_you_Back-sort.html may be of interest. Yes, the source is PayScale with all of its faults, but at last the by-major survey has far more samples per major than by-school surveys has per school.
@AlbionGirl: I understand that and, again, I am grateful, but the purpose of this thread is to give feedback on the DoE scorecard system, so that is what I am giving an opinion about, mainly.
As a comparison, my community college is listed in the first place on the TN scorecard database that you linked to, but the Department of Education has not done the same for whatever reason.
The OP hasn’t been around since September 21. I think we overwhelmed him!
And this thread is only 10 pages long, not a big one by CC standards at all 
In terms of aesthetics, the initial form seems to look a bit spammy and from the 90s. A better design would be beneficial.
