It’s hard to say whether reputation will translate into better job prospects. Each school has a section on its website which reports student earnings. However, we don’t know how reliable that information is, we don’t know the effect of students going to grad school instead of into the job market on that salary data, and we don’t know how any of this translates into the job prospects for any individual student at a particular moment in time. FWIW, Rose self-reports higher salaries for its graduates.
There are probably too many variables to forecast job prospects based solely on the perceived value of a school’s degree. Grades are going to factor into job and career prospects. At this point they are unknown. Probably the more relevant question is at which school is this student more likely to thrive? If he’s hardy enough to do well at either school, then Rose is probably not worth the price differential. OTOH, if increased interaction with faculty and Rose’s hands on approach to learning would be more likely to bring out the best in him, then it probably be worth it if you have the money to spare. But only if you have the money to spare.
