1. Any offender committed to the department of corrections, except those persons committed pursuant to subsection 7 of section 558.016, or subsection 3 of section 566.125, may receive additional credit in terms of days spent in confinement upon recommendation for such credit by the offender's institutional superintendent when the offender meets the requirements for such credit as provided in subsections 3 and 4 of this section.

The policy may reward an inmate who has served his or her sentence in an orderly and peaceable manner and has taken advantage of the rehabilitation programs available to him or her. Any violation of institutional rules or the laws of this state may result in the loss of all or a portion of any credit earned by the inmate pursuant to this section.

4. The department shall cause the policy to be published in the code of state regulations.

5. No rule or portion of a rule promulgated under the authority of this chapter shall become effective unless it has been promulgated pursuant to the provisions of section 536.024.
