And by "inaccurate," they mean only that the lists included non-law faculty or faculty who didn't teach at the school in question–they do not mean that the data itself actually reflects the opinon of law students about professors whose classes they really took.  No one has any way of confirming that. The editors have appended a list of articles on "Rate My Professors," but as I noted before, the literature (if you actually read it) does not support the use to which National Jurist put it.  They still should withdraw the entire ranking, and hire some educational and statistical consultants to come up with a worthwhile metric.
