Forty-one States and Provinces reported that they had current or continuing good time programs. Of the inmates involved, 85 percent to 100 percent have some sort of sentence reduction as a result of their behavior and participation in programs. Despite new legislation and public interest in mandatory sentencing, the use of good time as an incentive seems likely to continue. The opportunity to reinforce appropriate behavior during incarceration and to encourage participation in rehabilitative programs makes it an effective management tool. A small but notable group of U.S. States and the Correctional Service of Canada have "bad time" policies, whereby prisoners may have sentences expanded for misbehavior. Recent State legislation and changes instituted by departments of corrections have in some cases made the implementation of good time a complex issue for the public to understand and corrections officials to manage. Tables show good time applications by State and Province as well as good time policy provisions. Information on good time applications addresses the existence of a good time policy; provisions for awarding good time (maximum amount receivable, statutory days per month, and earned days per month); the application of good time to parole eligibility and release date; deduction from sentence (on entry and as earned); and assessment method for earned time awards. The table on good time policy provisions addresses rescission of good time, restoring good time, loss of good time, inmates excluded from earning good time, lifer eligibility, purpose of good time, and recent good time policy revisions.
