Legalfielder: Western State does use a curved grading system, but the median for the curve is set pretty low at a 2.4 - at least that's what it was for all my first year classes. The attrition rate is also attributed to transfers - a few students in my class that were going to be on FLP probation transferred out so they wouldn't risk being dismissed at the end of this semester.
Livinglegend: While I don't believe they want their students to fail out, they are weeding out those students who may or may not pass the bar in order to keep students who's chances of passing the first time are much higher. Since this system is not used by any other law school, it is a questionable one. If a student has a cum of a 2.5, but only two or three foundation points, it hardly seems fair to dismiss them based on that system alone after one year of law school because it's really impossible to say for sure whether or not they'll pass the bar on their first try, and that is my biggest issue with it.
