In addition to any good time credits earned and retained, the following shall apply with regard to program credit calculations:

(A) A system shall be developed whereby program credits may be earned by inmates for the successful completion of requirements for a general education diploma, a technical or vocational training program, a substance abuse treatment program or any other program designated by the secretary which has been shown to reduce offenders’ risk after release; and

(B) the amount of time which can be earned and retained by an inmate for the successful completion of programs and subtracted from any sentence is limited to not more than 120 days.

(2) Any time which is earned and subtracted from the prison part of the sentence of any inmate pursuant to program credit calculation shall not be added to such inmate’s postrelease supervision term, if applicable, except that the postrelease supervision term of a person sentenced to a term of imprisonment that includes a sentence for a sexually violent crime as defined in Kan.
