The Comprehensive Youth Services Act (CYSA), which was enacted in 1997 to fund juvenile probation services, had the following three basic goals: (1) keep probation youths from further crime; (2) help probation and at-risk youths develop essential skills to avoid dependence on public assistance; and (3) help achieve overarching federal Temporary Assistance to Needy Family (TANF) goals. In evaluating the success of CYSA/TANF in accomplishing these goals, the following five areas were explored: (1) program implementation; (2) services provided; (3) services and programs provided in juvenile halls and camps/ranches; (4) the impact at the individual and system level; and (5) the funding environment and county claiming experiences. Overall, county probation departments (CPD) appear to have closely followed the planning guidelines laid out in the CYSA. The 23 services eligible for CYSA/TANF funding were provided in the context of a number of different programs, and the CPDs used their CYSA/TANF funds both to add new services and to enhance existing services in the service delivery areas stipulated by the legislation. Lessons learned during the evaluation occurred in the following areas: (1) tightening legislative intent; (2) demonstrating program effectiveness; and (3) understanding the difference between large and small counties.
