Parole refers to a temporary release from prison or jail that requires supervision and the consent of officials. Parole is different from probation, which is supervised time used as an alternative to prison. Probation and parole can both follow a period of incarceration in prison, especially if the prison sentence is shortened. Most people in these situations are supervised by correctional officers or other appropriate professionals, including mental health professionals; they may attend regular meetings or counseling sessions and may be required to report on their activities and travel. People on probation or parole often have strict guidelines; not only will they be returned to jail upon committing a crime, but they may also be prohibited from associating with known criminals or suspects. These strategies are designed to prevent people on parole or probation from returning to criminal engagements, and to increase the likelihood that they will remain positive members of the community through interactions with family, productive employment, and mental health treatment if needed.
