In the past 50 years forensic psychological practice has expanded dramatically. Because the practice of forensic psychology differs in important ways from more traditional practice areas (Monahan, 1980) the "Specialty Guidelines for Forensic Psychologists" were developed and published in 1991 (Committee on Ethical Guidelines for Forensic Psychologists, 1991). These Specialty Guidelines for Forensic Psychology were developed by the American Psychology-Law Society (Division 41 of the American Psychological Association [APA]) and the American Academy of Forensic Psychology. They were adopted by the APA Council of Representatives on August 3, 2011.
