Christopher Zorn at Lawyermetrics recently posted an interesting discussion of law school employment outcomes by US News rank. Zorn's post includes a chart that shows the decline in various employment outcomes as US News rank drops, just as one might expect. One of the interesting and potentially unexpected features Zorn pointed out was the "steep drop in Bar Passage Required employment between the teens and the 50-60 range," which flattened out after #50-60.
In this post, I have replicated Zorn's plot below (although with markedly less appealing visual presentation). I also added a layer for large firm (501+ lawyers), represented by the dark green area at the very bottom of the image. Interesetingly, the steep drop noted by Zorn for bar passage required jobs is even more pronounced in this subgroup. Indeed, it looks like big law employment drops of extremely rapidly and that past #50 or so in the US News peer rank, big firm employment doesn't vary much with further declines in ranking.
In addition, there appears to be a second "dropoff" among the unranked schools that is more apparent in this plot than in Zorn's. Note that some of the changes in slope near the edges in both my plot and Zorn's are attributable to using rank orderings on the X-axis. If the raw peer score is used instead of the rank, much of the curvature to the JD required line disappears, but the "Big Firm" line continues to show the steeper dropoff from ranks 1-50 in US News. The dropoff would be even steeper if federal clerkships were added to the "big firm" numbers, as large percentages of students at elite schools enter clerkships upon graduation.
