It is the intent of the State Legislature that all new prisoners

sentenced to the custody of the Department of Corrections will be

processed through the Lexington Assessment and Reception Center or

at a place determined by the Director of the Department of

Corrections. The Department of Corrections shall ensure

administration of a risk and needs assessment, as defined in Section

502 of this title, physical and psychological examinations, mental

health and substance abuse screens, inventory vocational skills, and

assess educational and training needs. A risk and needs assessment

shall not be required for any inmate who had a risk and needs

assessment administered by personnel certified by the Department of

Mental Health and Substance Abuse Services within six (6) months of

being sentenced to the custody of the Department of Corrections.

The Department of Corrections shall determine initial security and

custody classifications, plan for immediate or possible future

assignment to an institution, community treatment center or other

alternative to incarceration authorized by law, provide orientation

and instruction with respect to rules and procedures for prisoners,

and perform other such activities deemed necessary by the Department

of Corrections.
