The Polygraph Institute LLC
Our school offers world class credibility assessment training, featuring both basic and advanced polygraph and forensic interview courses. Serving government agencies, law enforcement, and private security sectors, we have been accredited by the American Polygraph Association, and recognized by the American Association of Police Polygraphists for more than fifteen years. With a team of instructors boasting over 100 years of combined polygraph experience, we have graduated hundreds of polygraph examiners, achieving an impressive near 100% pass rate for licensing exams nationwide.
Our basic polygraph examiner course focuses on validated test formats, the Empirical Scoring System, and the use of computer-assisted scoring tools to make scientifically-backed decisions regarding truth and deception. Our forensic interview courses emphasize the use of free narrative techniques, enabling the identification of evidence-based cues to accurately determine truthfulness. For untruthful subjects, our psychology-based behavioral intervention methods are grounded in scientific approaches, designed to increase admissions and facilitate a better flow of information.
Our instructors are the creators of the Single-Issue Screening Test (SIST), a cutting-edge format for pre-employment and post-conviction sex offender testing. Known for its strong defensibility, the SIST is widely regarded as one of the most reliable polygraph tests for pre-employment, tactical polygraph, and sex offender supervision applications. By attending our courses, you’ll receive training directly from the developers of this widely-recognized test.
Additionally, we offer an exclusive one-year support period to graduates of our basic examiner course, ensuring that they have the resources they need to succeed. Enroll in our next course to join the ranks of our highly skilled and confident polygraph examiner graduates.
