Public Safety Performance Project is an initiative led by the Pew Charitable Trusts who is a nonprofit, non-governmental organization with a mission to serve the public interest by improving public policy, informing the public, and invigorating civic life. The Public Safety Performance Project promotes criminal and juvenile justice policies and practices that protect public safety, ensure accountability, and reduce correctional populations and costs. They focus on community supervision, jails, justice reinvestment and juvenile justice. The working methodology of the project is aimed at reforming jail, community supervision, and juvenile justice systems by helping jurisdictions safely reduce admissions to and the length of time people spend in jail; decrease the size of probation and parole populations so that community supervision agencies can focus their limited resources on the individuals with the greatest needs, implement best practices to increase successful outcomes, and reduce returns to jail and prison for new offenses and technical violations; reduce the number of young people entering the juvenile court system and improve the quality of services and supervision available in their home communities.
