This document is an assessment of the service needs of one state's juvenile court wards written by a group of representatives of private and governmental agencies involved in working with children in the juvenile justice system. The group's goals were to generate accurate program and fiscal information about the juvenile justice and juvenile service systems in Oregon and to use this information to guide analyses of state policies and to develop policy recommendations. The document describes research design, sampling design, and census. Results of a needs assessment survey on a representative sample of juvenile court wards are discussed; questions investigated included the following: (1) characteristics of sample court wards; (2) problems in client profiles related to juvenile court status or referral history; (3) the child's past or present danger of abuse, neglect or exploitation; (4) treatment settings needed by the wards; (5) the need to remove a child from his own home; (6) needed services; and (7) other information availability. Suggested areas of future research conclude the report. The survey instruments are appended. (ABL)
