    WHAT HAPPENS DURING A POLYGRAPH/LIE DETECTOR?
    There are generally three phases that will occur during a polygraph examination. Those are the Pre-Polygraph interview, the Polygraph Examination and Post-examination interview. Pre-Polygraph Interview Phase In the Pre-Polygraph interview phase, we will complete all the necessary paperwork and review the case with you. We will explain how the examination will be conducted and review all examination questions with you at that time. Polygraph Examination Phase In the Examination phase, we will attach the polygraph sensors to you. We will then ask all the previously reviewed questions. The physiological changes in your body will be recorded on a chart. Post-Exam Phase In the Post-examination phase, the polygraph charts are examined, using a numerical scoring system. The numerical scoring system will allow us to make one of three determinations: truthful, inconclusive or deceptive. When appropriate, the examinee will be given the opportunity to explain any physiological responses to one or more of the questions. The results will be given to the client as soon as practical, with a written report to follow.
