As a forensic social worker, your responsibilities are to gather information about criminal defendants. You may work on behalf of law enforcement, a court system, defense attorneys, or a state agency, such as child services, to make an assessment of the defendant’s mental status and develop a sentencing plan or alternative form of incarceration for the defendant. Your duties are to interview defendants, diagnose behavioral and mental health issues related to criminal behavior, and make policy recommendations to state agencies and judges. You may also act as an expert witness in a trial.
