Offender Services

Offender Services Bureau is responsible for the determination of offender release eligibility and institution assignment of all offenders committed to the Department of Corrections. Offender Services Bureau is comprised of:

  • Intake and Assessment
  • Offender Classification/Movement
  • Offender Information

Intake and Assessment

Offender Intake and Assessment for the Arizona Department of Corrections, Rehabilitation & Reentry takes place at four locations: Arizona State Prison Complex-Phoenix, adult males; Arizona State Prison Complex-Perryville, adult and minor females sentenced to death; Arizona State Prison Complex-Tucson, minor males sentenced as adults; and Arizona State Prison Complex-Eyman, Browning Unit, males sentenced to death. This process usually takes about 5-10 days to complete.  Inmates who are sentenced to six months or less to serve are usually processed within 3 days.  

During the period at Intake Assessment, offenders take part in Admission/Orientation and are classified under the Offender Classification System. Upon entering the Department's custody, each offender is assessed for security and custody risk, and for specific services such as medical, mental health, substance abuse or sex offense treatment and/or programming needs such as education, vocational training and work skills and other placement considerations.

Offender Classification/Movement

Offenders received into the Arizona Department of Corrections, Rehabilitation & Reentry are initially classified utilizing an objective Custody Classification System (CCS). The classification profile consists of an offender's custody classification and internal risk levels, as well as programming needs. Offenders are reviewed on a annual basis. Classification scores are adjusted based on information received during the review period to include behavior, time left to serve, and overall history. An offender's placement is changed when the custody classification indicates the offender  no longer meets the custody/security designation of the current unit assignment. A daily count sheet and vacancy report are generated each weekday. Count information is submitted through each complex Offender Information Unit (OIU) each morning. The count sheet includes information on beds, types by unit statewide, the number of offenders physically assigned, on out count and pending in the county jails. The Classification Unit schedules offender movement from the county jails and transfers between the prison units.
