The 1997 Washington State Legislature enacted the Community Juvenile Accountability Act (CJAA) to test the use of “research-based” programs to reduce juvenile offender recidivism. The act required the use of a risk assessment to assign youth to these programs. The Washington Association of Juvenile Court Administrators worked with the Washington State Institute for Public Policy (Institute) to develop the Washington State Juvenile Court Assessment (WSJCA). The assessment was implemented in 1999 as a two-stage process. The first stage is a pre-screen assessment completed for all youth placed on probation. The second stage, a full assessment, is required for youth assessed as moderate or high risk on the pre-screen. This report examines the validity of the pre-screen and full assessment.
