Nearly 70% of the entering class at the University of the District of Columbia David A. Clarke School of Law was black in 1998. A decade later, that figure hovered at around 30% — the lowest percentage among the country’s six historically black law schools.

The catalyst for that shift was a 1999 letter from the American Bar Association urging the school to examine its admissions standards and low first-time bar-passage rates. The school responded by accepting students with higher credentials, but the percentage of black students began to decline as the average Law School Admission Test (LSAT) scores rose.
