This brief, filed by Educational Testing Service (ETS), a non-profit educational corporation, deals with whether Test 21, a test of verbal ability developed by the U.S. Civil Service Commission and used by the Metropolitan Police Department of the District of Columbia to select police recruits, is sufficiently job-related to be legally permissible in selecting potential employees. As friend of the court, ETS presents a framework that utilizes technical evidence of test validity in an appropriate balance with the analytical judgments about fairness and rationality needed to implement properly the concept of job-relatedness under Title VII of the Civil Rights Act of 1964.
