Drake's law school, one of the 25 oldest law schools in the nation, traces its history to 1865. It is a charter member of the Association of American Law Schools; has been accredited since 1923, when accreditation began; and is one of only 75 ABA-approved law schools with a chapter of the Order of the Coif. Drake University Law School is home to the American Judicature Society; the archives of the National Bar Association, the nation's oldest and largest national association of predominately African-American lawyers and judges; and the Drake Constitutional Law Center, one of only four constitutional law programs established by the U.S. Congress and funded by the federal government.
