Very helpful post!
Back in the day, we used to use a reference called Rugg’s Recommendations, which listed (I am paraphrasing) recommended schools (by selectivity) for majors. Fred Rugg updated his book yearly until 2018 (35th edition), adding new majors that hadn’t been previously listed. (I still have the 34th edition on my computer!). It also (again, back then) listed expected standardized test scores by major. Those were additional pieces of data that helped with the college search. We did not look at outcome data in part b/c it wasn’t a driving factor in either kid’s decision. Starting salaries wasn’t their driving issue, and while yes, where kids ended up working after college was interesting, not uncommonly the top place on many schools’ lists is working back at that very college!
Both my kids changed majors, so even if we had taken outcome data, even understanding its potential weaknesses, into consideration, the info would have mattered little if they had made their college choices based in part on job placement from their initial intended major. So outcome data based on career starts or companies employed would have ultimately been meaningless for them.
Whats even more interesting is that my kids went to different schools, started with different majors, both then ended up pivoting to engineering (though different types), started in very different jobs in different cities, and through several different opportunities and job changes over the years, ended up working for the same company and now even have the same job title!!
Point being, there are lots of variables to look at when choosing colleges to apply to. We were full pay (except for the NMS) for one kid, and the other kid had a full tuition scholarship (plus NMS). So the cost difference to us was notable, but they were both happy at their schools, have done well, and we are all thrilled with the outcome. And if they had looked at outcome reports, even with the potential limits of those self reports, and especially limiting in small schools and/or with a low response rate, they might have looked at other schools that weren’t the radar, or eliminated some that were. Bottom line, WRT outcome reports, they can add some information to the overall research, but caveat emptor.
eta:
Hopefully it’s clear- we paid very different amounts for each kid’s college tuition. Their first jobs were very different (each chose different types of jobs based on their specific area of engineering) but regardless of placement data, regardless of first job salaries (they were, IIRC, pretty similar starting salaries, adjusting for the fact that one was a few years later than the other), they ended up in the same place with the same job title (I don’t know their current salaries. Not my business).
