The Residential Substance Abuse Treatment (RSAT) program, administered through the Bureau of Justice Assistance (BJA), was created to help States and units of local government develop, implement, and improve treatment programs in State and local correctional and detention facilities. It also helps them create and maintain community-based aftercare services for probationers and parolees. Prison- and jail-based (residential) programs provide services to offenders before their release. In these programs, offenders are usually housed apart from the general population. Aftercare programs are provided in community settings after offenders have been released. RSAT programs provide substance abuse treatment and other services such as housing, education, and vocational assistance. This Program Performance Report is divided into two sections: 1) jail- and prison-based programs, and 2) aftercare programs. It should be noted that State-based correctional facilities are included in the prison-based data section and the report is based on self-reported data from grantees and sub-recipients.
