The NYT reports on a study by my UCLA law school colleague Rick Sander:
Thanks to vigorous recruiting and pressure from corporate clients, black lawyers are well represented now among new associates at the nation’s most prestigious law firms. But they remain far less likely to stay at the firms or to make partner than their white counterparts. A recent study says grades help explain the gap. To ensure diversity among new associates, the study found, elite law firms hire minority lawyers with, on average, much lower grades than white ones. That may, the study says, set them up to fail.
The study, which was prepared by Richard H. Sander, a law professor at the University of California, Los Angeles, and was published in The North Carolina Law Review in July, has given rise to fierce and growing criticism in law review articles and in the legal press.
Sander has done a great deal of work on affirmative action in law schools, you can access his various studies and reports here.
