An objective classification system uses classification instruments that have been validated for inmate populations, applies the same classification approach for all inmates, assigns inmates to custody levels consistent with their backgrounds, and provides for staff to manage similar offenders the same way. The NIC-sponsored jail objective classification system uses evaluation tools that meet criteria for validity, reliability, equity, and utility. The 3-part system consists of an inmate screening form, an initial custody assessment, and custody reassessment. The inmate screening form uses a checklist format that addresses four assessment factors: substance abuse needs, suicide risk, mental health needs, and medical health needs. The initial custody assessment identifies inmates with special needs and determines each inmate's custody level. Custody reassessment involves the continuous monitoring of an inmate's behavior while confined to ensure that custody levels are reflective of current behavior. This evaluation provides incentive for good behavior through structured rewards and punishments.
