Do You Offer Polygraph Exams /Lie Detector Tests to the Public?

Yes. We now provide our professional polygraph services to the general public on a case by case basis. Please contact us for more information.

How Much Does a Polygraph / Lie Detector Test Cost?

Please contact us for current pricing.  A small, non-refundable deposit is required at the time of scheduling and the balance is due on the day of the appointment.

How Does the Process Work?

The first step is to contact us by phone or email and tell us a little bit about your situation. We will then discuss scheduling, pricing, the process etc.

I’m Nervous About the Process, Is this Normal?

Yes, it’s perfectly normal to be anxious/nervous about the polygraph exam and this is understandable. We take measures to make the process as stress-free as possible and we conduct the exams in a non-confrontational manner. Unlike what you may see in the movies, no one will yell at you or interrogate you. We conduct professional polygraph exams in a respectful manner regardless of your situation, background etc.

Do You Accept Walk-Ins?

The office is not staffed full time, as we frequently conduct exams at various other locations, so you must schedule an appointment. Same day and after-hours appointments may be available depending on availability.

Who Comes Up With the Questions Being Asked?

The examiner will work with the client and/or their partner/spouse/associate/lawyer to develop the questions that will cover the issue to be resolved while ensuring the questions are in a format accepted by the professional polygraph community. For accuracy, the number of questions that can be asked per exam is limited. This is not our policy, this is based on APA guidelines for accuracy.

I Am Taking A Polygraph For a Job with Law Enforcement.  Can You Give Me Any Advice or A Practice Test?

We don’t give practice tests to police or fire applicants and in the past, examiners have been sent to federal prison for this practice.  We would advise the applicant to rely on the information provided by the agency they are testing for and listen to the examiner on the day of the exam. Be honest, take responsibility for your previous actions, and  avoid tips you may see online, as well as any anecdotal advice from friends or family.

What Does the Polygraph Exam Procedure Involve?

Prior to attaching the examinee to the polygraph components, all test questions are thoroughly reviewed with the examinee, word for word. There are no surprise or trick questions asked. During the test phase, the examinee’s psycho-physiological responses are rec­orded as the examiner asks each question and the examinee responds with a “yes” or “no” an­swer. Our expert examiners will make that determination on the basis of your responses on the test and rely on each of the instrument’s components, much the way that physicians rely of them in a diagno­sis of your health. Some of the polygraph recording devices provide either similar, or identical readings as medical equipment used in the diagnosis of a patient.

The same questions are repeated on separate polygraph charts. At the completion of the final chart, the examiner analyzes all polygraph charts to determine whether the examinee’s answers indicate truth or deception.
