Appendix: Discretionary Parole Grant Rates by state, 2019-2022

The Prison Policy Initiative collected these numbers from a mixture of publicly available information and open records requests for our briefing on parole grant rates. Where possible, we have linked the publicly available data. We calculated parole grant rates by looking at the total number of hearings where parole was a possible, but not a mandated, outcome, and then looking at the number of those hearings that resulted in approval. In many states, there are also various kinds of “nondecisions” which postpone someone’s consideration for parole. In effect, these nondecisions prolong someone’s time in custody, just like a denial would. In some states, the official published calculations of their “grant rate” look only at hearings that were “granted” or “denied,” ignoring the sometimes large number of hearings where release was possible, but the board did not make any decision, even though it had the power to. Where possible, we do include those nondecisions in our calculations. Because of this difference in definition, the grant rates reported here may be lower than the “grant rates” reported in some official state reports.

Note about California: Because California does not have a true discretionary parole system (i.e. it offers parole only to certain "exceptional" categories of people), we did not include it in this briefing. However, in December 2023, upon request, we published a briefing examining California's use of discretionary parole for certain people.

Massachusetts 4,294 3,625 2,578 2,279 2,764 2,007 1,585 1,583 64% 55% 61% 69% 8% -43% As mentioned in the methodology statement above, Massachusetts is a state that does not include nondecisions in the denominator of its grant rate calculation. However, Massachusetts’ reports also do not differentiate between nondecisions in discretionary parole hearings and nondecisions in revocation hearings, making it impossible for us to include nondecisions in our denominator (as we did for other states) without including many hearings that were not discretionary parole hearings at all. For this reason, we did not include nondecisions in these numbers. These grant rate numbers include only hearings where the result was “granted” or “denied” – likely inflating Massachusetts’ apparent parole grant rate in comparison to other states.

It is important to note that the Utah parole board sometimes grants parole with years of delay between the hearing and the release. These long parole dates are recorded as grants, but in practice, still lead to substantially more incarceration after the hearing.
