FIU will certainly be an accredited law school soon and will easily be Tier 3. It may nose up to the lower reaches of Tier 2 before long. If you want to practice in FL, go there. For everywhere else, I repeat, Case Western Reserve is a major, prestigious university. Every well-educated person I have ever met knows that. If you get a good scholarship to mitigate the outrageous tuition, go there. The reputation of the outstanding university rubs off on the merely good law school.
No one outside of Florida knows FIU from a hole in the ground, nor will FIU ever become a top university. Florida State is consistently ranked below Case Western Reserve. Where does that leave FIU?
