I think Employment Prospects is what matters most and all the schools are lying about their prospects except probably HYS.
US News should say they are revamping the way they evaluate employment statistics so that school's can save face when they have been reporting like 90%+ employment with like 10% reporting.
Create a metric where you only measure "legal" jobs to get rid of the starbucks kids, and for every non-reporting graduate you penalize the school enough that it is in their best interest to get every student reporting even if they are unemployed or working a shit job.
The 2 problems with reporting currently IMO is (1) the selective reponse rate (with schools only seeking responses from employed/successful new grads) and (2) reporting the employment % without considering the type of employment.
Practically, with no other publications or the ABA stepping up, I think you have to work within US News to correct abuses of their system, knowing the law schools as a general rule are unethical, lying, and completely self interested to the detriment of future law students.
