Minority representation among lawyers is less than 9.7 percent, compared to 20.8 percent among accountants and auditors, 24.6 percent among physicians and surgeons and 18.2 percent among college and university teachers, says Chambliss, citing U.S. Census figures. Among students, minority representation has dropped the past two years, from 20.6 percent in 2001-02 to 20.3 percent in 2003-04, with the biggest slippage among African Americans. After law school graduation, minorities are less likely than whites to win judicial clerkship positions, or to go into private practice, and more likely to begin their careers in government or public interest jobs. In top-level jobs, fewer than 4.4 percent of partners in the nation's largest 250 firms and only 4.3 percent of corporate general counsel are minority. Chambliss reports that minority women are almost completely excluded from top private sector jobs. Chambliss cites an over reliance by law schools on Law School Admissions Test scores and by legal employers on law school rankings, class rank, law review membership and clerkships as barriers to minority students and lawyers, and adds that minorities in law firms lack access to clients and business networks.
