When I was a student at Fordham, I worked very closely for the former Dean, Bill Treanor on a number of projects. He showed me the infamous Fordham study on BTLs and asked me for my impressions – not because I was a BTL myself, but because I was obviously orthodox and learned (we discussed halachic perspectives on various legal issues often).
Anyway, I can confirm that although as Popa said the study’s conclusions seem strange, the study did indicate that BTL’s LSAT scores or “undergrad” grades were poor predictors of their law school performance, and that 80% of BTL law students over a period of over a decade had placed either in the top 10 or bottom 10% of the class, with no apparent way of predicting were they would end up, and without any equal distribution between those two percentiles. Consequently, the study recommended severely curtailing acceptances of BTL, and certainly to avoid offering them scholarships because there was little way to predict that any particular BTL student would end up doing well and getting a good job after school, thereby extending the schools alumni network, ect.
