After reviewing the nature and content of the education of child psychologists, the discussion addresses the ethical issues of patients' informed consent and right to confidentiality. Since part of the child psychologist's role on a child protection team is to facilitate the effective interaction and functioning of the team, characteristics of a successful child protection team are outlined: mutual respect and support among team members, acceptance of the families, and flexibility. Aspects of the psychological assessment of children are assessment of the developmental level and possible emotional abuse as well as issues unique in the assessment of abused or neglected children. The psychological assessment of parents encompasses reaction to assessment, childhood history, impulse control, problemsolving, relationship with children, and possible mental disorders. The psychological assessment of family interaction involves observation of marital interaction during interviews and the observation of siblings in a playroom accessible to the psychologist. The discussion of the use of psychodiagnostic tests also addresses the use of psychological test results as evidence in court. Consideration of resources for psychologists working alone, student training, and research conclude the paper. 90 references.
