This paper describes the development of a standard measure of juror usage in the 94 United States District Courts and explains how this measure is becoming a recognized quality standard through the self-enforcement of many court administrators and judges. The effect of the standard is to cut expenditures by reducing the number of jurors called while ensuring that those called will be effectively utilized. Of all those called to jury duty, the federal courts use only a small percentage, whereas the state and local courts use the great majority. The problem, therefore, is how to get this standard of juror usage recognized and used by the thousands of state and local courts.
