The type of facility will tell you exactly what the classification your son was designated. Classification codes refer to the assessment of the offender's level of risk, or their needs. The lower the number the higher the risk. Prison classification is a method of assessing inmate risks that balance security requirements with program needs. Upon admission, processing and evaluation of offenders begins. They are put through a series of evaluations, including medical and mental health screenings. Prison classification specialists develop an individual profile of each inmate that includes the offender’s crime, social background, education, job skills and work history, health, and criminal record, including prior prison sentences. Based on this information, the offender is assigned to the most appropriate custody classification and prison. From this initial classification, inmate behavior and continuing risk assessments by prison staff will determine the inmate’s progression through the various custody levels to minimum custody and eventual release. Prison managers assign inmates to work, rehabilitative self improvement programs, and treatment. As inmates serve their sentences, the inmates who comply with prison rules, do assigned work, and participate in corrective programs, may progress toward minimum custody. Inmates who violate prison rules are punished and may be classified for a more restrictive custody classification and a more secure prison. Inmates are then required to demonstrate responsible and improved behavior over time to progress from this status to less restrictive custody classifications and prisons. The security rating system has five tiers which are: A1 - high security A2 - maximum security B - medium security C1 - minimum security C2 - minimum security Maximum security units are comprised of cells with sliding cell doors that are remotely operated from a secure control station. Maximum security units are designated by the Director of Prisons at selected close security prisons. These units are utilized to confine the most dangerous inmates who are a severe threat to public safety, correctional staff, and other inmates. Inmates confined in a maximum security unit typically are in their cell 23 hours a day. During the other hour they may be allowed to shower and exercise in the cell block or an exterior cage. All inmate movement is strictly controlled with the use of physical restraints and correctional officer escort.
