Valid, WUSTL is a much better school. I would argue ku is a better investment.
But there is no way Washburn and ku are on the same level. Maybe 10-15+ years ago. Also, ku already is a tier 2. Washburn is...well...not.
I would then argue that buying a dunkin donuts franchise is a better investment than any law school but who goes to law school without a schollie paying a good chunk? Bottomline, ku is decent if you want to work in wichita/kc/topeka and maybe ok city or tulsa. Besides that, that name carries no weight. I am sure you can relay several stories of "well so and so I know got a job at Sidley in Chicago" to which I can reply with 10 more stories of recruiters from large firms (the kind that pay enough for you to retire your student loan debt in 3 years, thus making it a great investment) who see "ku law" on the resume and send it to the circular file. Bottomline, if you are happy sticking here and don't want a diploma that gives you national options, I suppose you could do worse.
It is a bad school for being the only school in the state and for the resources it has and many of the people who go/went there will readily admit they went because they got in state tuition, not because they thought it was respectable.
When did ku crack the 2nd tier?
