Which model describing the duties of probation and parole officers see clients as wards whom officers are expected to control?

The model that describes the duties of probation and parole officers as seeing clients as wards whom officers are expected to control is the "Custodial Model." This approach emphasizes supervision and control, viewing clients primarily as individuals who require management and oversight to ensure compliance with the terms of their probation or parole. Officers in this model focus on enforcement and risk management rather than rehabilitation.
