Parole provides community supervision to offenders released by the State Board of Paroles and Pardons to finish serving their sentences outside of prison, subject to certain conditions. Offenders are classified based on their need for services and risk of committing new offenses. Offenders on parole must pay a supervision fee based on a sliding scale determined by monthly income. Special conditions may be imposed by the Board to further restrict freedom, limit movement in the community, add further punitive measures, or to require rehabilitative services. Violation of any of the standard or special conditions of parole may result in the imposition of additional punitive sanctions, up to and including sending the offender back to prison.
