Forensic assessment is to provide a medical, psychiatric or psychological assessment to assist the Court in its deliberations. While treatment issues may emerge in the assessment process, the primary purpose is legal and not medical or psychological.
Forensic assessment is used when a psychologist is hired to answer a specific legal question (i.e. competency, insanity, etc.). Depending on the specific question, the psychologist will conduct a clinical interview, collateral interviews (e.g. with witnesses, family, friends, attorneys, police officers, etc.) review records (i.e. medical, psychological, criminal, school, etc.), administer psychological tests, and form an opinion to answer the legal question
