Choosing a Polygraphist

What is a Polygraph?

A polygraph is a device that makes a permanent recording of various physiological changes taking place within the body of the test subject as a result of certain psychological stimuli.

Who is a Polygraph Examiner?

A person who purports to be able to detect deception or verify the truth of statements through the use of instrumentation or by the means of mechanical devise; and has graduated from an American Polygraph Association approved basic polygraph examiner course of instruction or approved by the Tennessee Polygraph Commission.

How does a Polygraph work?

The polygraph records physiological responses of an individual attached to a polygraph instrument.

What does the Polygraph record?

A polygraph records, breathing, heart rate, blood pressure and galvanic skin resistance.

Does a polygraph detect lies?

No, a polygraph records physiological responses through series of questions presented to an individual by a qualified polygraph examiner using a validated testing format. The epoligrapher is then able to examine the chart data and render a diagnostic opinion as to the veracity of the subject being tested.

Can an employer use a polygraph to test an employee suspected of causing an economic loss?

Yes, if the employer has reasonable suspicion. The employer must be able to articulate the reasonable suspicion, and reduce it to writing, access alone does not constitute reasonable suspicion. Additional information can be found in the Federal Register/Vol. 53, No. 204 / Friday, October 21, 1988 Rules and Regulations pages 41497 through 41510 (Employee Polygraph Protection Act). An employer may not take any personnel action based solely upon the results of a polygraph examination.

How accurate is a polygraph?

The American Polygraph Association says the polygraph is 85% to 95% for specific issue investigations. There are studies on record that suggest polygraph is even more accurate.

How many questions may be asked?

Question numbers are determined by the format being utilized by the examiner.

Will I know what questions are on the test?

Yes, all questions are reviewed with the examinee prior to any polygraph testing. Each question requires an answer of either “Yes” or “No”.

Can I be forced to take a polygraph exam?

No, polygraph exams are always voluntary.

How long does a polygraph exam take?

A polygraph test is a three phase test; the pre test, chart collection phase, and the post test. Examinations require a minimum of sixty minutes, but often take longer.

Should I stop taking my medication before the test?


Choosing a Polygraphist

In the state of Tennessee, there are literally hundreds of persons who offer lie detection services and choosing one can be very difficult. The best way to determine the polygraphists' credibility is to assess their reputation in the area where they do business. Obtain the services of a polygraphist who will render an objective opinion and who is respected for this ability.

The following are some things to look for when engaging the services of a qualified polygraphist.

  1. Make sure the individual is a certified graduate from a polygraph school which has been accredited by the American Polygraph Association or the American Association Police Polygraphers.
  2. Make sure the individual is a member of at least one or more of the National Professional Polygraph Associations.
  3. Request a Curriculum Vitae from the individual which will outline the polygraphists’ education and work history.
  4. Make sure that the individual is keeping abreast of the latest in polygraph technology by attending on a regular basis seminars and/or classes related to polygraph.
  5. Do not be afraid to ask questions about the individual’s qualifications and references.
  6. Check with the State of Tennessee Polygraph Commission and Licensing Board to ensure your polygraph examiner is licensed to conduct polygraphs in the State of Tennessee.

Do not get caught up in the myth that cheapest is always best. It takes a great deal of time and effort to properly conduct a polygraph examination. Prices will vary, but just remember you usually will get what you pay for.

Reputation, education, certification, membership and credibility are the key elements in the selection an expert polygraphist.
