The Society of American Law Teachers (SALT) has released the results of its 2012-3013 Salary Survey, reporting the median faculty salaries and summer stipends at 68 of the 200 American law schools -- most law schools did not respond.
For those schools that did respond to the survey, the salaries range from the 120,000's to the 180,000's for full-tenured professors. Most also get a summer stipend.
Not too shabby! Although, it would be interesting to also see teaching loads and/or publications listed along with salary to get the full picture of what this salary covers. The teaching loads are likely internal information, so the law schools would have to comply with another request -- one that feels a bit like an investigation.
