Correctional Service Canada has these core programs that have been tested, validated, evaluated, and that have demonstrated they have the desired impact. They change behaviour, and the measure is often one of recidivism.
These programs are rolled out in various sites at various times. Not every institution offers all the programs all the time, and even those institutions that list a catalogue of programs may not have, for a variety of reasons, all the programs in their catalogue available on any given day.
We will typically see 25% of offenders engaged in a core correctional program at any given time. That has less to do with the motivation of the offender and more to do with the ability of the service to put the program in place and deliver it.
