The Polygraph Institute LLC
The Polygraph Institute offers world class credibility assessment training, featuring both basic and advanced polygraph, and forensic interview courses. Our school, and team of instructors with more than 100 combined years of experience, have been accredited by the American Polygraph Association and the American Association of Police Polygraphists for many years. Our school has an impressive record of multiple accreditation inspections with zero deficiencies. We have trained students from government agencies, police departments, sheriff's offices, and the private sector from more than sixteen countries worldwide graduating students with an impressive near 100% pass rates for polygraph licensing exams.
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), the only research driven screening format for pre-employment and post-conviction sex offender testing. Known for its strong evidence based approach, the SIST is widely regarded as one of the most accurate and 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 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. Our school is an advocate for mentoring and proficiency testing for field examiners following graduation. Contact us for these advanced services.
