First of all, there are a number of factors that need to be considered when we classify an offender. We consider institutional adjustment, escape risk and risk to the safety of the public, and under each of those factors there are many subfactors.
We also use actuarial tools, which parole officers complete. Again, if the actuarial tool says one thing, and they're looking at something else that doesn't correspond, then they need to ask themselves some more questions.
In terms of the decision, for the most part the decision is made by the institutional head, although in certain cases it's more elevated than the institutional head.
