The old Leiter Law Rankings site is going offline August 20, so readers who want any of the material there should copy it before then. I am going to post here some of the data that strike me as particularly useful, starting with data on placement in law teaching.

===========

This study is based on the educational credentials of all tenure-track and tenured law faculty as of Spring 2008.  (The underlying data comes from this interesting article.)  This excludes adjuncts, legal writing instructors, and other ‘faculty’ who are not in tenure-stream positions.  But it still covers more than 7,000 faculty at AALS-member law schools. 

Bear in mind that faculty in this sample graduated from law school over a very long period of time, from the 1950s through to nearly the present; schools whose reputations were stronger long ago may do better here than they would in a study confined only to recent hiring, while schools whose reputations have improved over time will likely fare worse here.    Circa 1960, for example, it would have been common to think of Yale, Harvard, and Columbia as clearly the top three law schools, with Penn, Michigan, and perhaps Chicago just a notch below.  Stanford rose to prominence during the 1950s and 1960s, and Chicago’s competitive position improved significantly with the rise of law-and-economics in the 1970s, where it was the primary innovator.  NYU and Georgetown both became far more prominent schools starting in the 1970s as well.  (You can get some sense of the small reputational shifts since the 1970s from this data.)   Columbia slipped out of the “top 3” during the 1960s, Penn slipped out of “the top five” by the 1970s, and Michigan did the same in the 1990s.  Thus, the data below to some extent reflects the large time period covered, which mostly explains the differences (where there are differences) with data focusing on more recent placement in law teaching.

There are two rankings, below.  The first is an attempt to take account of the fact that schools differ quite a bit in the number of students they graduate.  I call it a ‘per capita’ measure, but that’s not what it really is:  it is just an attempt to adjust the results to reflect differences in the pool of graduates each school produces.  (The formula used was to divide the total number of graduates in law teaching by the average number of graduates of the school [rounded to the nearest 25] in recent graduating classes.)  The second ranking is based on the total number of graduates of each school in law teaching.  Gross numbers have some importance too:  alumni in teaching often favor (or at least look favorably upon) graduates of their school, and schools with large numbers of graduates in law teaching are ones whose graduates hiring schools expect to be looking at every year.

Because the ‘per capita’ figure is a rough measure (based on estimates of class size), I’ve created more ties as the numbers became smaller in order to give a more realistic sense of peer clusters. 

I.  Ranking by “Per Capita” Number of Graduates in Law Teaching (“per capita” here really means the total number of graduates divided by the average size of a recent graduating class rounded to the nearest 25)
