  1. After completing the appropriate forms, the examiner will begin the pre-test.

  2. During the pre-test, the examiner will thoroughly discuss and review the case (the reason for taking the test and the events which preceded the test).  The client and examinee will then jointly agree on the pertinent test questions including the scope of each- What is included and/or excluded in each question.

  3. The number of relevant questions is determined by the nature of the case and usually does not exceed (4) four unique questions.  The limit is a professional standard, from the test's reliability standpoint and has nothing to do with pricing. There are no surprises during the test, and all questions will be reviewed with the examinee before the initiation of the lie detector test.

  7. The entire test questions will then be verified with the examinee, explained and reviewed prior to the test.
