This chart highlights sentence credit policies listed in state statutes that are applicable to people in state prisons. Earned time is defined as a credit against a sentence or period of incarceration that a person earns for participation in or completion of productive activities. Earned time is distinguished from, and can be offered in addition to, “good time” credits, which are given for following prison rules and participating in required activities. A more detailed chart can be found in this PDF.
