How are jurors selected for a trial in the United States?

In the United States, the selection of a jury is designed to ensure a fair trial by drawing a random cross-section of the community from the general population.1

The Selection Process

• Venire: The process begins with a large panel of prospective jurors, known as a venire, who are summoned for service.2
• Exemptions and Hardship: While selection is intended to be random, jurisdictions may exempt specific professional groups (such as police or doctors) and excuse individuals if service would impose an undue hardship.1
• Voir Dire: Once the panel is assembled, the court conducts voir dire, an elaborate screening process where the judge or attorneys question prospective jurors to detect potential bias or preconceived notions regarding the case.21
• Challenges: During voir dire, attorneys may dismiss jurors in two ways:
  • For cause: Dismissing a juror due to a specific, demonstrated likelihood of bias.21
  • Peremptory challenges: Dismissing a limited number of jurors without providing a specific reason.21

For grand juries, jurors are randomly selected from lists of registered voters, with the court typically choosing 16 to 23 individuals.3
