(a) The opportunity to earn good behavior allowances offers the resident a tangible reward for positive efforts made during confinement.

(b) For any resident serving an indeterminate sentence, other than a life sentence, who is not granted parole or a reparole, but who nevertheless has performed well within division secure facilities, good behavior allowances can be used to obtain release under supervision and to demonstrate, prior to completion of the term of the sentence, that the resident can follow acceptable behavior patterns in the community as well as in a division facility.

(c) In the case of a resident sentenced to a definite term of one year or less, good behavior allowances can be used to shorten the term of the sentence.

(d) Good behavior allowances are a privilege to be earned by the resident. No resident has the right to demand that any good behavior allowance be granted to him.
