Parole and probation are employed in the punishment phase of the criminal justice process. Parole comes into play after a person has been imprisoned and is released subject to supervision by an officer of the court. Probation, by contrast, refers to a criminal sentence separate and distinct from incarceration. Probation is the most frequent sentence imposed for less serious or first offenses and typically involves releasing the convicted offender into the community subject to a list of terms and conditions. Both parole and probation may include additional conditions, like attending drug education classes or receiving drug treatment.
