Under the United States District Court for the Middle District of Florida's Plan for the Qualification and Selection of Grand and Petit Jurors, voter-registration lists are the primary sources for identifying prospective jurors. Every odd-numbered year, prospective jurors are selected randomly from county voter-registration lists, and their names are put into the divisional Master Jury Wheel. Prospective jurors are then sent a juror-qualification questionnaire, which they must complete and return to the court to verify that they are qualified for jury service. Those who qualify for service might be summoned to report for service.
