A Georgia study found that the average cost of ISP per offender was $694.83 as compared to comparable incarceration costs of $25,215.13. Additional cost benefits were found to accrue as a result of probationers' earnings, taxes, restitution, fees and fines, and community service. ISP costs in New Jersey were estimated at $7,000 per offender per year as compared to $17,000 for incarceration. Similar savings were found in a program in Lucas County, Ohio. In a Washington State evaluation of intensive parole, comparison costs of incarceration, supervision, clerical support, community resources, and recidivism were calculated for intensive parolees and regular parolees. Results indicated a lower cost for intensive paroless ($5,546 versus $11,599). While these results suggest that ISP's are cost-effective, such analyses have assumed that ISP participants would otherwise have been incarcerated and that secondary costs and benefits can be accurately measured. Future studies should attempt to measure the full range of costs and benefits of ISP's more systematically. Such a comprehensive analysis will allow for more informed policy decisions. 23 references.
