Parole is a form of early release of a prison inmate where the prisoner agrees to abide by behavioral conditions, including checking-in with their designated parole officers, or else they may be rearrested and returned to prison.

A probation or parole officer is an official appointed or sworn to investigate, report on, and supervise the conduct of convicted offenders on probation or those released from incarceration to community supervision such as parole. Most probation and parole officers are employed by the government of the jurisdiction in which they operate, although some are employed by private companies that provide contracted services to the government.
