I’m still in high school but considering environmental law. At this point I highly doubt I could get accepted into an Ivy league college, but I’m hoping for Georgetown or Boston University. If I go to law school I’d like to go to a top tier school like Harvard, Yale, or Columbia. Do they really take into consideration what college you went to? I know that studying at Harvard will look better than studying at some unranked community college, but how do schools like Georgetown, BU, and NYU compare against schools like Harvard and Yale in law school admissions? And how much does it even matter?
LSAT and GPA are the two most important factors. The impact of undergrad is likely slight. Coming form a more prestigious undergrad does sometimes mean that your GPA or LSAT can be a little lower (e.g. the average LSAT of an undergrad from an Ivy admitted into a top tier law school may be 1-2 points lower than the average admitted LSAT for that school in general). Obviously correlation not causation, but still worth noting.
A slight boost probably exists at a lower level for schools like NYU, BU, Georgetown, etc. Though I haven’t seen those stats so I have no idea.
Georgetown appears to be top-notch in terms of admission to highly regarded law schools:

@stressedsopho: There is no evidence supporting the claim that law schools care about your undergrad institution. Even assuming they did, the impact would be minimal. Sometimes employers care about your undergrad institution, but any of the ones you have listed should be fine.
