Classification and Population


The Classification and Population unit is responsible for the administration of several units including: reception and assessment of all offenders sentenced to the agency from 77 counties through the Lexington Assessment and Reception Center, initial and reclassification of all inmates, population office, and all central transportation units located at three sites across the state. The administration area sets policy and procedure for the agency, bed space management, system count, monitoring and implementing legislative changes as they relate to classification and programs.

Office Units

Assessment and Reception of Inmates

Male inmates with felony convictions and sentenced by the courts to the Department of Corrections are received by the Assessment and Reception Center (A&R) located in Lexington, Oklahoma, while female inmates are received by Mabel Bassett Correctional Center in McLoud, Oklahoma.  The seventy-seven counties schedule transportation to A&R.   

The Oklahoma Department of Corrections’ philosophy is that inmate re-entry begins at entry.  As such, inmates serving 100 years or less undergo a complete needs assessment to determine what treatment the inmate requires to reduce their probability of recidivism.  Case plans are established utilizing objective assessments; to determine the need for substance abuse treatment, and/or cognitive behavioral programs.  Inmates are also classified to maximum, medium, or minimum security. The inmate’s custody level is determined utilizing the most serious current offense, seriousness of previous offenses; escape risk, number of prior convictions, and additional risk factors.  Placement of inmates at facilities is made to meet the department’s mission of protecting the public, staff and inmates.

Population Office  

The Population Office is responsible for scheduling all inmate movement throughout the Department of Corrections, including contract facilities. In order for an inmate to move from one location to another, the facility must submit a transfer packet. The population staff are responsible to ensure that the inmate is correctly classified and eligible for placement at the requested custody level; balancing the need of the offender to move to lower levels of custody for reintegration purposes and maintaining the safety of the public.

Central Transportation Unit

The Central Transportation Unit (CTU) is responsible for transporting all inmates.  Once inmates receive their initial classification at the Assessment and Reception Center they move to their initial placement.  As well, when inmates become eligible for lower levels of security, need additional structure at higher security, or need a program located elsewhere, this unit ensures the inmate is transported in a safe and secure manner.   

CTU has three sites located around the state; located at the Lexington Assessment and Reception Center, John Lilley Correctional Center and the Jackie Brannon Correctional Center.  

CTU is also responsible for the OU Medical Center and the Lindsay Municipal Hospital.
