6. Probation Process for Parolees and Those Granted Sentence Reduction

The probation process for parolees and those granted sentence reduction consists of six steps

  • 1

    Case Acceptance This step occurs when the Probation Office receives a probation release notification from a prison/correctional institution. The case administration officer will register the case into the central system, compile documents to establish the case file by using the existing inquiry file of that case as a continuous monitoring file, and then assign it to the head of the work group or a delegated person, who will consider and assign the case to a probation officer.

  • 2

    Clarification of Probation Conditions and Information Gathering This step involves the probation officer's operations when the probationer reports to the probation officer as per the probation release notification from the prison/correctional institution. The probation officer will conduct an orientation, clarifying the order and probation conditions to the probationer, as well as collecting factual evidence about the probationer and scheduling reporting appointments.

  • 3

    Analysis and Planning In this step, the assigned probation officer will analyze and evaluate various information concerning the probationer's background, the nature of the offense, and the circumstances of the case. They will then plan the rehabilitation and corrective measures for the probationer by using criteria for risk or likelihood of re-offending and criteria for identifying problems and needs for offender classification.

  • 4

    Supervision and Monitoring of Conditions / Rehabilitation This is the operational step where the probation officer supervises, monitors, and assists offenders based on their risk level or likelihood of re-offending and the severity of their problems and needs. This ensures that probationers comply with probation conditions and receive rehabilitation to modify their behavior, become good citizens, and prevent recidivism.

  • 5

    Evaluation and Summary of Results In this step, the probation officer must review the performance in each case file. The probation officer must review the operational plan and re-evaluate the risk and problem/need assessment at specified intervals to ensure that the assigned rehabilitation activities or probation plan are being implemented according to the plan, thereby adjusting the probation plan to be effective in rehabilitating the probationer.

  • 6

    Preparation of Probation Report This final step involves the probation officer reviewing the case file and compiling information regarding the completed probation of the offender, both in cases where conditions were met and where they were not. This information is then compiled into a probation report to be submitted to the Department of Corrections.
