Parole is the release of a prison inmate before the end of their maximum sentence. However, parole can be revoked at any time for a number of reasons. If a parolee breaks any of the conditions of their parole, they are sent back to prison to finish out their sentence.
Parole Officers supervise parolees and try to ensure that they're able to reintegrate back into society and adjust to their new lives.
Their work often starts before an inmate is released; a parole officer will develop a post-release plan covering areas such as accommodation, finding work, and reconnecting with friends and family.
Parole officers' ultimate goals are to reintegrate their parolees into society, keep them out of prison, reduce crime rates, and help keep citizens safe.
