Polygraph questions? Call 818-248-5600 for answers.

The three most important factors in obtaining a test result with high accuracy are:

1. A properly trained Polygraph Examiner - (our examiner received approved training by an American Polygraph Association Accredited School)

2. A thorough pre-test interview to insure the issue at hand is fully understood clearly by both the examiner and examinee - (there are no surprise questions during a real polygraph test)

3. Test questions accurately designed to verify the truth of a single issue. - (most polygraph on television depict random, emotion-inducing, surprise questions on a variety of subjects. Those type of tests, although entertaining, have no verifiable validity or accuracy)
