A person is qualified to be a juror if that person is over age 18, a United States citizen, a resident of the county, able to communicate in English, and has not been convicted of a felony for which civil rights have not been restored. Jurors are randomly selected from a master jury list made up of the list of registered voters, licensed drivers, and identicard holders in each county. 

Jury Service. The court sets the length and number of jury terms within a 12-month period, subject to statutory requirements. Jurors are summoned for a jury term, which is the time that a summoned juror must be available to report for jury service. In counties with a jury source list that has at least 70,000 names, the jury term may not exceed two weeks, and the term of juror service may not exceed one week except to complete a trial.  In counties with a jury source list that has less than 70,000 names, the jury term may not exceed one month and the term of juror service may not exceed two weeks except to complete a trial.
 
It is the policy of the state to maximize the availability of residents of the state for jury service, and to minimize the burden from jury service.  Statute instructs that the jury term and juror service should be set at as brief an interval as is practical given the size of the jury source list for the judicial district.  The optimal jury term is one week or less.  Optimal juror service is one day or one trial, whichever is longer.
 
Excusal From Jury Service. No person may be excused from jury service except upon a showing of undue hardship, extreme inconvenience, public necessity, or any reason deemed sufficient by the court, for a period of time the court deems necessary.  A prospective juror excused from juror service for a particular time may be assigned to another jury term.  When the jury source list has been fully summoned and additional jurors are needed, jurors who have already served may be summoned again for service.  A juror who has previously served may be excused if they served at least one week of juror service within the preceding 12 months.

A person who is 70 years of age or older may request to be excused from jury service if the person attests they are unable to serve due to health reasons. A court must grant this request, and may not reassign the person to another jury term in the same 12-month period. Courts may not require a doctor's note, and must develop attestation forms.
