FREQUENTLY ASKED QUESTIONS




WHO CAN HIRE A POLYGRAPH EXAMINER?
polytest image 0101 - Who can hire a private polygraph examiner? [view answer]
0101 - Anyone can request a polygraph exam for any reason, provided the test does not violate any local, state or federal laws. The person taking the exam must be willing to do so, and can not have any physical or mental impairments that could affect the ability of the examiner to collect valid data. Note that in the U.S. there are significant restrictions on employers wishing to test employees. [hide answer]
polytest image 0102 - Can I have a polygraph exam done on myself? [view answer]
0102 - Yes. Many clients come to us looking to prove their innocence to someone else. [hide answer]
polytest image 0103 - If I'm charged with a crime should I take a private polygraph? [view answer]
0103 - If you are innocent, it may be a good idea to take a private polygraph. A large number of the exams we provide are in defense of criminal charges or allegations. While many (but not all) states prohibit using polygraph evidence at trial, it is still used extensively by police and prosecutors to help decide whether to move ahead with a case. If the exam is done through an attorney, the results will only be released if they are favorable to your case. If you have been asked by law enforcement to submit to a polygraph, you should not do so without advice from your attorney. [hide answer]
polytest image 0104 - Can a sexual assault victim take a polygraph to prove they were assaulted? [view answer]
0104 - Yes, except in a few U.S. states where it is illegal to polygraph sexual assault victims (Texas and Washington are two of these states). [hide answer]
polytest image 0105 - Can a U.S. employer request that an employee take a polygraph? [view answer]
0105 - Yes, but only under certain conditions and if the state does not have a law prohibiting these types of exams. For more information about testing employees in the Unites States CLICK HERE [hide answer]
polytest image 0106 - If I failed an exam somewhere else can I do a retest with GPN? [view answer]
0106 - Yes, of course. Many of our customers come to us because they were not pleased with the outcome of a previous polygraph exam. Not all examiners are created equal, and frankly some are not very good at their job. If you feel you received a substandard exam we would be happy to provide you with an independent test. [hide answer]
polytest image 0107 - Does GPN offer testing for fishing and other sporting tournaments? [view answer]
0107 - Yes, most of our examiners will provide polygraph services to sporting tournaments. Many of our members regularly test for fishing and bodybuilding tournaments. CLICK HERE for more information. [hide answer]

polytest image 0203 - How can I review the credentials of my local GPN examiner? [view answer]
0203 - On our web pages listing the individual exam locations you can click on the "more info" icon next to a particular testing location for more details and background about the examiner who covers that location for us. [hide answer]
polytest image 0204 - Why must I register in order to get the name of my local examiner? [view answer]
0204 - Our examiners are all under contract with GPN to provide high-quality polygraphs at an agreed-upon price. However, GPN is not a "yellow pages" for polygraph services. You will be hiring one of our pre-screened members directly, and customers must register with our headquarters before our examiner will schedule your exam. We will not provide examiner details without first receiving the customer's information. If you wish to review the examiner's credentials, these are available on our web site by clicking on the "more info" icon next to the testing location that you are interested in. [hide answer]
polytest image 0205 - Why must I register before I'm given the address of my local testing facility? [view answer]
0205 - Most of our examiners travel extensively and none of them take walk-in customers. Exams are done by appointment only. In addition, most of our examiners use multiple facilities within a given area based on space availability, so the examiner does not always provide exams at the exact same location. The exact location for the exam will be given to you by the examiner when you book the appointment. If the location indicates "at customer location" that means we do not have a regular testing facility in that area and it is the customer’s responsibility to provide a suitable room for the exam. [hide answer]
polytest image 0206 - What does it mean when an examiner is PCSOT (Sex Offender) Certified? [view answer]
0206 - This acronym stands for "Post Conviction Sex Offender Testing" and is a specialized certification for polygraph examiners who wish to provide testing for persons convicted of sex crimes who are required to take periodic polygraph exams to verify issues surrounding their parole/probation and/or therapy/treatment. This certification process requires the examiner to complete a 40 hour APA-accredited training program and to meet other mandated requirements. [hide answer]
polytest image 0207 - Is a computerized polygraph better than an analog (old style) polygraph? [view answer]
0207 - Mechanical (or analog) polygraph equipment has been around for nearly 100 years, and some examiners still use this type of equipment. At the start of the 21st century computerized polygraphs were developed. These new systems included complicated chart analysis formulas (algorithms) and inkless display systems (on a computer screen rather than a roll of chart paper). Scoring of the charts is handled the same for both systems, but the computerized system has built-in aids for the examiner and prevents equipment failures that are sometimes experienced with mechanical equipment. A competent and qualified examiner can be equally effective with either system. [hide answer]
polytest image 0208 - When would I want to use a court-qualified polygraph expert? [view answer]
0208 - When an examiner is court-qualified, that means that the examiner has previously been permitted to testify in a legal proceeding by a judge or arbitrator. If you are planning to use your polygraph results as evidence in a legal proceeding, it is often advantageous to hire an examiner who has previously testified. Having this credential will make the judge's decision easier regarding whether to admit that examiner's testimony. This does not mean that examiners who have not testified are less qualified, however. Many high quality examiners have not yet had an opportunity to testify in support of a polygraph exam. [hide answer]
polytest image 0209 - Can I have GPN’s owner Michael Martin handle my exam personally? [view answer]
0209 - Michael has dozens of regular testing locations throughout NY, NJ, PA, DE and MD. Please visit the listings for these states and look for locations that have Michael's name attached. If none of these locations is convenient for you, contact us HERE for a special quote for Michael to handle your exam personally.

polytest image 0307 - How do I avoid the GPN "copycats?" [view answer]
0307 - Since GPN is the world's oldest and largest polygraph referral service, there are a number of "copycats" who are pretending to be the "Global Polygraph Network" to fool customers into thinking they've found the real thing. Don't fall for it. The real GPN is headquartered in upstate New York, owned by polygraph expert and author Michael Martin, and maintains a Better Business Bureau Rating of A+. You can trust GPN for your polygraph needs, but make sure you are dealing with the REAL Global Polygraph Network. [hide answer]

0308 - It is GPN's policy that its members will not discriminate based on ethnicity, gender, religion, sexual orientation, or handicap. However, in the case of cognitively impaired individuals, our members must assess the ability of that person as a suitable polygraph candidate. [hide answer]


COST OF A POLYGRAPH EXAM
polytest image 0401 - How much does a polygraph (lie detector) test cost? [view answer]
0401 - GPN has nearly 500 testing locations worldwide, and each location commands a different price. Visit our Test Locations & Fees page to search for the testing location most convenient for you. The prices per exam will appear next to each location name. The average price for an exam in the United States is about $600, but prices vary from $300 to over $2000 depending on the location. To reach our Test Locations page CLICK HERE.
[hide answer]
polytest image 0402 - What do I get for the fee that I pay? [view answer]
0402 - For the fee listed you will receive a polygraph exam administered by a trained and experienced polygraph expert at the location you selected. Once the exam has been completed, you are entitled to a written report of the examiner’s findings at no extra charge. The published fee is for testing on weekdays during business hours. Some examiners will charge extra for weekend and evening exams. [hide answer]
polytest image 0403 - Why does a polygraph cost so much? [view answer]
0403 - Polygraph examiners are highly trained professionals, most with college degrees, who provide a very specialized service. This service requires the examiner to purchase expensive equipment and pursue continuing education in order to maintain a high degree of proficiency. The process of asking "just one question" could take hours, due to the diagnostic process involved, so a single exam often takes an examiner an entire working day (including travel). In most cases, the polygraph is performed because there simply is no other reasonable way to get the desired information, such as when no evidence exists one way or the other, or when it is simply a "he-said she-said" situation. For example, in a fidelity case a person might spend thousands of dollars on surveillance while the same information could be obtained for a fraction of the price with polygraph, resulting in thousands of dollars saved. The fees charged for polygraph testing are reasonable when considering the cost of training and equipment, degree of specialization and worldwide need for this unusual service. GPN does not set the fees charged by its members. [hide answer]
polytest image 0404 - Why do prices for tests vary so much from location to location? [view answer]
0404 - Like any other private business, the price of a polygraph test is "market" driven. In some areas the exam may be as low as $300 while in others it is $2000. The fee is usually determined by supply and demand. GPN does not set the fees charged by its members. [hide answer]
polytest image 0405 - Where can I get a less expensive polygraph? [view answer]
0405 - Of course you can find less a expensive polygraph examiner out there, but how much trust are you willing to put in the results of a "discount" polygraph? Any examiner who charges less than $300 is probably using out-of-date equipment, has inadequate training, or has not kept up with the latest technological advances in polygraphy. We suggest that if budget is a large issue, look for qualified examiners outside of your local area and be willing to drive several hours to get there. In most cases if you are willing to travel you will find less expensive polygraph services by qualified examiners. The Zip Code Search feature (U.S. only) on our web site can help you with this search, and will list our ten nearest locations. CLICK HERE to learn how to protect yourself from polygraph frauds. [hide answer]
polytest image 0406 - Do you offer discounts for volume testing (3 or more people)? [view answer]
0406 - In most cases we do offer discounts for volume testing (3 or more tests). Please click on "more info" next to the testing location to see if volume discounts are available at that location. [hide answer]
polytest image 0407 - Do you offer discounts for couples? [view answer]
0407 - If both parties in a relationship wish to be tested regarding relationship issues, most of our examiners offer discounts off the second exam. Read the "more info" section next to each testing location to determine if a discount is available for couples testing. [hide answer]
polytest image 0408 - Will there be any additional fees beyond the published price? [view answer]
0408 - The fee listed on our site is the all-inclusive price for one polygraph exam with three or less primary (relevant) questions conducted during normal business hours. However, additional charges may be incurred for -

(3) use of audio or video recording equipment
(4) exams conducted after business hours or on weekends
(5) examiner's testimony in court or other proceeding
(6) testing in correctional institutions
(7) sales tax if required.
[hide answer]
polytest image 0409 - Why is a deposit required and is my deposit refundable? [view answer]
0409 - Nearly half of all clients who schedule appointments without a deposit do not show up for their appointments. The deposit helps insure that clients are serious about moving ahead with their exams and are not using it merely as a tool to try to extort information from someone. The deposit is NOT an additional fee - it is part of the overall fee that is listed for a given location. The deposit also constitutes GPN's referral fee. Your designated examiner may also request a second deposit to secure your appointment, but again, this is not an additional fee, just part of the overall published fee. In most cases the deposit is not refundable. However, if your GPN examiner declines to provide your exam, or does not offer you an appointment within 30 days, the deposit is refundable. If you (the customer) change your mind, ignore the examiner's attempts to reach you, or cancel the exam for any reason, the deposit is forfeit and we must receive another deposit prior to scheduling with us a second time. [hide answer]
polytest image 0410 - How much of a deposit is required? [view answer]
0410 - The actual deposit amount varies by test location. You can find the deposit amount for any location by clicking on the "more info" button next to that testing location. [hide answer]
polytest image 0411 - What is GPN’s cancellation policy? [view answer]
0411 - GPN examiners will require at least 24 hours notice of a cancellation or the customer will be responsible for the entire exam fee. Individual members may have more restrictive policies. CLICK HERE to review the complete policy. [hide answer]
polytest image 0412 - What methods of payment does GPN accept? [view answer]
0412 - Deposits for polygraph services and referrals can be paid for by any major credit card, debit card, prepaid debit card, Paypal, or by money order. Regarding the balance of the fee, which is payable directly to your examiner, that is up to the payment policy of each examiner. Many GPN members accept credit cards, debit cards, and Paypal, but some do not. Please discuss payment terms with your examiner when you speak with him or her. [hide answer]
polytest image 0413 - How can I pay the deposit if I don't have a credit card? [view answer]
0413 - If you don't have a credit or debit card, you still have three ways to pay for the deposit on your exam -

(1) Many stores sell prepaid debit cards which you can purchase. These prepaid cards (also known as gift cards) can be used to order services through GPN. Just make sure the card has either a Visa, Mastercard, Discover, or American Express logo on the front. You can supply this card information just as you would with any regular credit card.

(2) You can use Paypal to pay for your deposit. Paypal is a secure online payment service which can be linked to a checking or savings account. Simply request that we send you a Paypal invoice for your deposit (valid email address required).

(3) You can mail us a money order for your deposit, but this will significantly slow down the process since your exam will not be scheduled until the money order has been received and processed at our headquarters.
[hide answer]
polytest image 0414 - Can I make payments for my exam? [view answer]
0414 - Once your deposit has been paid, most examiners will allow you to make payments towards your final balance. Understand that the exam will probably not be scheduled until the full fee has been collected by your examiner. [hide answer]
polytest image 0415 - Are the test prices on the GPN web site up to date? [view answer]
0415 - Yes. The prices that are published on the GPN web site are updated several times per week. [hide answer]
polytest image 0416 - Can I get a free polygraph anywhere? [view answer]
0416 - GPN does offer free polygraph testing at some locations, but there are requirements that must be met. Free exams are only provided to defendants in criminal cases where either charges have been filed or the client has been found guilty and is seeking a new trial. In exchange for this free exam, clients must allow the results of the polygraph to be released to the media regardless of the outcome of the test. Free exams are not available for civil cases or domestic (relationship) issue tests. Contact GPN owner Michael Martin for more details about this program. [hide answer]


WHO CAN TAKE A POLYGRAPH?
polytest image 0501 - Who can take a polygraph exam? [view answer]
0501 - Provided the test does not violate any local, state or federal laws, anyone over 18 can take a polygraph exam for any reason. Children under 18 can be tested in some cases with written permission from the parent or guardian. [hide answer]
polytest image 0502 - What if the person has a medical condition? [view answer]
0502 - A polygraph exam does not cause any physical injury to the person being tested. The only discomfort is a standard blood pressure cuff which is typically wrapped around the upper arm and is inflated for 6 to 7 minutes at a time. However, there are increased stress levels during the testing process which should be considered. Some medical conditions are sensitive to increased stress levels, such as some heart conditions. Depending on the medical condition, most examiners would require an approval from the treating physician prior to conducting an exam on someone with such a condition. To download GPN's medical release form CLICK HERE [hide answer]
polytest image 0503 - Will medications affect the test results? [view answer]
0503 - Yes. Any drug or medication that suppresses normal activity of the Central Nervous System (sedatives, anti-anxiety meds, blood pressure stabilizers, etc.) will reduce the strength of reactions found on the polygraph charts, resulting in a higher likelihood of inconclusive results. However, these medications will not change the outcome of an exam and will only serve to reduce the odds of resolving the problem. It would be our suggestion to test any person using these types of drugs or medications on a computerized polygraph which is capable of greater sensitivity than the analog version. [hide answer]
polytest image 0504 - Can a blind, deaf or mute person take a polygraph? [view answer]
0504 - Yes, although testing a deaf person will require a "signing interpreter" who can either sign the questions or display flash cards. [hide answer]
polytest image 0505 - Can an incarcerated person be tested? [view answer]
0505 - Yes. However, testing in prisons requires making special arrangements, usually through an attorney, to insure that an adequate room is provided which is free from interfering noises and distractions. You should also discuss test duration with the examiner so that sufficient time is allotted for the test. The exam fee may be higher than listed, particularly if the examiner's office is not nearby, due to the extra time required for travel and passing through security procedures at the facility. [hide answer]
polytest image 0506 - Can a pregnant woman be tested? [view answer]
0506 - It does not affect the outcome of a polygraph exam to test a pregnant woman unless the fetus is making excessive movements or causing pain to the mother during the exam. Many examiners will not test a pregnant woman under any circumstances, but others are ok with testing after the first trimester. Some examiners will test only with a note from the woman's physician stating that there are no complications from the pregnancy and that the stress of taking a polygraph would not impact the health of the mother or fetus. Note: Examiners in Texas are not permitted to test pregnant women. To download GPN's medical release form Click Here [hide answer]
polytest image 0507 - Can a U.S. employer request that an employee take a polygraph? [view answer]
0507 - Yes, but only under certain conditions and if the state does not have a law prohibiting these types of exams. For more information about testing employees in the Unites States CLICK HERE [hide answer]
polytest image 0508 - Is it legal for a job applicant in the U.S. to submit to a polygraph? [view answer]
0508 - It depends. A job applicant in the United States can be asked to take a pre-employment polygraph exam if their employer falls under one of the following exemptions AND if the state does not have a law prohibiting these types of exams. If you are asked to take a polygraph to get a job with any company that is not on this list, it is an illegal exam.

EXEMPT EMPLOYERS:

(1) Government agencies
(2) Law enforcement
(3) Security companies
(4) Armored car companies
(5) Power generating companies
(6) Companies that sell or transport pharmaceuticals
[hide answer]
polytest image 0509 - What is the minimum age of a person that can be tested? [view answer]
0509 - The minimum age to take a polygraph varies by examiner, but ranges from 12 to 16 years old. Anyone under 18 who wishes to be tested must obtain written consent from a parent or guardian. Children under 12 years old are not able to produce reliable polygraph results. Your examiner will provide you with a parental consent form if necessary. [hide answer]
polytest image 0510 - Can a person be forced to take a polygraph exam? [view answer]
0510 - No. A polygraph exam must be taken voluntarily. In some cases a judge can order a polygraph exam to be taken, but it is still up to the examinee whether to cooperate with the court order or deal with the consequences for violating it. [hide answer]

polytest image 0603 - Can anyone hire a polygraph examiner? [view answer]
0603 - As long as the client is over 18 years old, the person taking the test is willing, and the request does not violate any laws, we can handle requests from anyone. Our client base includes the general public, attorneys, therapists, corporations, law enforcement, the media, and government agencies. If a U.S. employer wishes to test an employee, care must be taken to comply with the federal EPPA regulations which govern the testing of employees in the United States. [hide answer]
polytest image 0604 - How long does it take to get an appointment through GPN? [view answer]
0604 - From the time we receive and process your registration and deposit, it normally takes 7 to 10 days to get an appointment, depending on individual examiner availability. Some times it takes longer, some times less. It is our guarantee that you will be offered an appointment date within 30 days unless we have published that your examiner is unavailable. [hide answer]
polytest image 0605 - What days and hours are available for testing? [view answer]
0605 - We offer testing at 500 different locations, so the available days and hours will vary from one location to another. Most testing locations are available during business hours Monday through Friday, but many are also available on weekends and evenings. You can check on the hours for a particular location by clicking on the "more info" button next to that location on our Test Locations page. [hide answer]
polytest image 0606 - Does GPN offer "rush" service? [view answer]
0606 - Not at this time, but rush service will be available soon at many GPN testing locations. [hide answer]
polytest image 0607 - Do I need an attorney to hire a polygraph examiner? [view answer]
0607 - No, an attorney is not required to use the services of a polygraph examiner. However, in some cases it may be wise to have your attorney hire the examiner so that any information the examiner may have will be protected under attorney-client privilege. [hide answer]
polytest image 0608 - How often can someone take a polygraph? [view answer]
0608 - We do not recommend any person being tested more than 4 times per year under any circumstances. For best results a person should not be tested more than 2 times in a 12 month period. [hide answer]


PREPARING FOR THE EXAM
polytest image 0701 - How should someone prepare to take the exam? [view answer]
0701 - For best results, the person taking the polygraph should be well-rested and free of any extraordinary fatigue or stress factors on the day of the exam. This means getting a good night's rest, eating a meal before the test, and avoiding stressful situations (arguments, interrogations, emergencies, medical procedures) on the day of the exam. If the person is in any pain, we suggest postponing the exam until the cause of the pain has been remedied rather than attempting to control the pain with medication. If the person is taking regular prescription medications he/she should continue taking those medications. If the prescription medications are taken infrequently "as needed" then we generally advise not to take these medications until after the exam. It is ok to take aspirin or other mild over-the-counter medications, which should have no affect on the exam. The examinee should avoid illegal drugs and alcohol for 12 to 24 hours prior to the appointment. It is normal to be concerned about the exam and a certain amount of anxiety will be expected by the examiner. [hide answer]
polytest image 0702 - How can I convince someone to take a polygraph? [view answer]
0702 - You must present the polygraph exam as an opportunity for the person to clear his or her name or disprove something that can not be disproved any other way. The person being tested should not be accused of anything prior to the exam. Pretest discussions should always be calm and rational. There must always be a perceived benefit for the person to take the exam, and this benefit must be made clear. It is also sometimes helpful to indicate that refusing to take the exam will provide your answers anyway (except in employment situations where this statement would not be legal to make), so the person has everything to gain by submitting to the test. [hide answer]
polytest image 0703 - How much notice should I give to the person I want tested? [view answer]
0703 - Under no circumstances should you surprise someone with a polygraph exam. We recommend giving at least one week's notice, but never less than a few days. If the person taking the exam is one of your employees (in the United States) you must give that person written notice at least 2 business days before the exam date. [hide answer]
polytest image 0704 - Should I provide the examinee with the test questions before the exam? [view answer]
0704 - No. There are many rules for question design that must be followed. In addition, the final version of the test questions may be changed based on the examiner's interview. It is OK to provide the general nature of the intended questions to the examinee before the polygraph, but not the exact questions. [hide answer]
polytest image 0705 - Why is a medical release form required for some medical conditions? [view answer]
0705 - Taking a polygraph exam does not cause any physical injury to a person. However, going through a polygraph procedure can be stressful. Our examiners must take steps to ensure that the increased stress of a polygraph is not likely to affect the health of the person being tested. This release form is usually required for anyone with a heart condition or anyone who is pregnant, but may also be required for any other medical condition at the discretion of the examiner.

polytest image 0706 - What if the person being tested needs an interpreter? [view answer]
0706 - In some cases the person being tested may not be fluent in the language used by the examiner. In these cases we recommend that an interpreter be used. The interpreter must not be personally acquainted with the person to be tested and must have no interest in the outcome of the exam. In other words, we suggest hiring a professional interpreter. Note that the fees for an interpreter are not covered in the exam fee and must be paid separately. [hide answer]


EXAM QUESTIONS
polytest image 0801 - Who makes up the test questions? [view answer]
0801 - There are many rules for question design (see below). Our examiner will work with the client to develop the best possible questions to resolve a particular situation. Each exam is custom-made to suit the needs of our clients. In addition to the relevant questions (which address the primary test issue) the examiner will add a number of other questions (non-relevant) to establishing baselines and aid in scoring. [hide answer]
polytest image 0802 - Can I provide my own questions for the exam? [view answer]
0802 - There are many rules for the design of polygraph questions which must be followed. Normally you will explain your situation to the examiner and that examiner will then work with you to come up with the best questions to resolve your situation. You can provide a list of suggested questions if you like, but these questions must be approved (or modified) by your examiner before they can be used. [hide answer]
polytest image 0803 - How many questions can be asked? [view answer]
0803 - Research statistics on polygraph accuracy are all based on a single-question single-issue exam, which is the most accurate format possible. As more relevant questions are added to an exam, the overall accuracy of the exam goes down. While a single-question exam is the most accurate technique, some clients need to resolve more questions than just one. In those cases, we still do not recommend asking more than 3 or 4 relevant questions in a single exam, and these questions must be related to one another. We can not "mix issues" in a polygraph exam. If you need to cover more than 3 or 4 relevant questions or need more than one issue covered, we will have to conduct more than one exam.

If the polygraph results are to be used in a legal proceeding, you must use the most accurate and scientifically validated method available. This requires that only a "specific issue" format be used covering one item only per test. Other formats (such as multiple issue tests) do not have the accuracy levels needed to be used as evidence. [hide answer]
polytest image 0804 - What kinds of questions can be asked? [view answer]
0804 - Any fact-based question can usually be addressed in a polygraph exam, but there are several rules for question design that must be followed (see below). [hide answer]
polytest image 0805 - What are some of the rules for proper polygraph questions? [view answer]
0805 - There are quite a few rules for designing proper polygraph questions. Your examiner will work with you to develop the best questions for your situation, but here are some of the basic rules for relevant question design.

(1) All polygraph questions must be answered with a "yes" or "no." Narrative answers are not permitted. Normally, "no" answers are expected from suspects and "yes" answers are expected from victims and witnesses.

(2) Questions can not be subjective or ambiguous. Each question must be interpreted the same way by any person who hears it. When in doubt, specific words or phrases can be defined and agreed-upon before the exam.

(3) Lengthy questions are not permitted. A question that takes more than 6 or 7 seconds to ask (using normal speech) is too long.

(4) Hypothetical questions are not permitted.

(5) Questions about opinions, emotions, feelings, or the future can not be used. For example, examiners can not ask if someone loves you.

(6) Compound (multi-part) questions are not generally used.

(7) Questions about lying are not generally used. Polygraph questions are asked in the most direct way possible. For example, we would ask "Did you steal the missing wallet?" and not "Are you lying about stealing the missing wallet?"

(8) Questions in the same exam must be related to one another. Examiners can not mix issues in a test. For example, an examiner can not ask questions about "stealing" and "using drugs" in the same exam. Each new issue requires a separate exam.

(9) If the polygraph results are to be used in a legal proceeding, you must use the most accurate and scientifically validated method available. This requires that only a "specific issue" format be used covering one item only per test. Other formats (such as multiple issue tests) do not have the accuracy levels needed to be used as evidence. [hide answer]
polytest image 0806 - Do you handle relationship and infidelity matters? [view answer]
0806 - Yes.  All of our examiners are highly trained in this area and will help you resolve those personal issues that are important to you.  In addition, in 2012 GPN's owner Michael Martin published the first textbook for polygraph examiners regarding Domestic (Relationship) Issues. For more information CLICK HERE. Caution: The State of Maine (U.S.) has a law prohibiting examiners from asking questions about sexual activities. [hide answer]
polytest image 0807 - Can one polygraph exam include questions about different topics? [view answer]
0807 - In most cases no. A polygraph should only cover one subject matter at a time - topics can not be mixed within a test. For example, you should not ask about "theft" and "drug use" within the same test, and you should not ask about "infidelity" and "assault" within the same test. If you need to cover more than one topic you will need to run more than one exam. Multiple issue formats are usually reserved for employment screening situations where several issues of equal importance are covered and accuracy is not as critical as in some other scenarios.

If the polygraph results are to be used in a legal proceeding, you must use the most accurate and scientifically validated method available. This requires that only a "specific issue" format be used covering one item only per test. Other formats (such as multiple issue tests) do not have the accuracy levels needed to be used as evidence. [hide answer]
polytest image 0808 - Can you test about something that took place a long time ago? [view answer]
0808 - Absolutely. As long as the person being tested has a clear recollection of the events in question and understands the consequences of his/her actions, the test will function properly. There is no rush to have the test done. A delay will not affect the results. [hide answer]
polytest image 0809 - Will there be any surprise questions on the test? [view answer]
0809 - Absolutely not. It is mandatory for all examiners to review all the test questions with the examinee before being attached to the polygraph instrument. [hide answer]
polytest image 0810 - Should I provide the examinee with the test questions before the exam? [view answer]
0810 - No. There are many rules for question design that must be followed. In addition, the final version of the test questions may be changed based on the examiner's interview. It is OK to provide the general nature of the intended questions to the examinee before the polygraph, but not the exact questions. [hide answer]
polytest image 0811 - Does GPN provide polygraphs for federal employment and clearances? [view answer]
0811 - Many federal agencies require polygraphs for job applicants. While we can certainly provide these exams, it is not likely that our results will be accepted by the agency without prior approval from that agency. It would be better to contact the agency directly for a list of pre-approved polygraph vendors. [hide answer]


THE TESTING PROCESS
polytest image 0901 - What is it like to take a typical polygraph exam? [view answer]
0901 - For a description of what it's like to take a typical private polygraph exam CLICK HERE [hide answer]
polytest image 0902 - Why can it take up to 3 hours to ask just one question? [view answer]
0902 - Polygraph is a diagnostic procedure and in reality is nothing like you might see on television. The exam begins with a collection of background information, both from the client and from the examinee. The examiner must then explain the procedure and psychological principles being used. An interview then follows where the case information is discussed in detail. After this, the examiner designs the test questions and reviews those questions with the examinee. Next, the actual testing phase begins where the examinee is attached to the polygraph and is asked the questions that were reviewed. This exam may be done from 3 to 6 separate times, not including any calibration procedures. After all the exams are completed, the examiner must review all the materials and render a decision. In some cases a post-test interview is also conducted by the examiner to discuss the results. [hide answer]
polytest image 0903 - What does a polygraph measure? [view answer]
0903 - A standard polygraph instrument records changes in blood pressure, pulse rate, pulse strength, galvanic skin reflex (sweat gland activity) and upper and lower breathing patterns. It does not matter if the examinee is "nervous" during the testing process - that is to be expected. The polygraph records significant changes from the subject's "norm" when specific questions are asked. A person intending deception to a particular question will activate his/her Sympathetic Nervous System as a "self defense" mechanism when that question is asked on the test. The SNS activation will cause recognizable changes in one or more of the physical responses.  For more information CLICK HERE [hide answer]
polytest image 0904 - What attachments are used to collect data from a person? [view answer]
0904 - When someone takes a polygraph exam, there are mandatory sensors and optional sensors, depending on the examiner's preference and technique used. Here is a list:

MANDATORY SENSORS:

(1) Blood pressure cuff. This is wrapped around the bicep, forearm or ankle to measure changes in blood pressure and pulse rate.
(2) Electrodermal sensor pads. These are attachments normally (but not always) placed on the hand or fingers, and can consist of metal plates or stick-on pads. These measure changes in the electrical activity within the skin (either skin conductance or skin resistance).
(3) Respiration tubes. These are soft rubber tubes placed around the upper and lower torso to measure breathing changes.
(4) Motion sensors. These are sensitive pads which can be placed under the buttocks, under the arms, or under the feet of the person being tested. These sensors are sometimes hidden inside a chair mechanism. These sensors measure any abnormal movements or muscular contractions within the person.

OPTIONAL SENSORS:

(5) Blood volume monitor or PLE. This is normally clipped onto the person's finger to measure changes in blood volume. As blood is drawn toward the body's core it leaves the extremities, resulting in lower blood volume in the fingertips.
(6) Finger cuff. This is a small blood pressure cuff that measures blood pressure changes at the fingers.
(7) Audio or video recording devices.
(8) Headset and/or microphone. The person taking the test may be asked to wear a headset (like stereo headphones) to eliminate outside noises from the exam. The examiner would speak into a microphone which would then be heard over the headset.
[hide answer]
polytest image 0905 - Does a polygraph hurt? [view answer]
0905 - The only component of a polygraph that some people find uncomfortable is the blood pressure cuff that is inflated on the examinee's upper arm for about 6 minutes at a time. The cuff is identical to that used by a doctor, but the pressure in the cuff will be significantly less than what you would experience at a doctor's office. It is normal to experience some arm tingling during the exam from the cuff. Other than the blood pressure cuff, the other polygraph components can barely be felt at all. There are no injections, no electric shocks, and no attachments to the head or face. [hide answer]
polytest image 0906 - Does being nervous affect the test results? [view answer]
0906 - No. In fact, polygraph equipment does not measure nervousness. Being nervous is a generalized condition that is expected to exist throughout the entire exam. The reactions that polygraph examiners look for only last a few seconds. In other words, a person isn't "nervous" just when certain questions are asked. If you are taking the exam, try to relax and remember that this is your opportunity to show people what the truth really is. Make it work for you. [hide answer]
polytest image 0907 - Why is it important to use a "validated" testing method? [view answer]
0907 - A validated testing technique is method of testing (and an associated scoring system) that has been subjected to scientific validation for accuracy. Not every technique and scoring system used today has been validated, so be certain to make sure the technique used by your examiner has been validated. To find out if your examiner is using a validated technique, ask him or her which validated technique they are using and what scoring system they are using. You can contact the APA and ask if this technique and scoring system has been validated for the type of test that was conducted (either a specific issue or a screening test). Note that specific issue tests must be validated to be at least 90% accurate, and screening tests must be validated to be at least 80% accurate. [hide answer]
polytest image 0908 - Is there a best time of day to give a polygraph? [view answer]
0908 - Yes. Since it is important that the person tested be capable of maximum psychophysiological reactions (for scoring purposes), that person should be well rested prior to the exam. In other words, testing done in the morning will be more productive than those done later in the day, and testing done in the evening significantly increases the risks of an inconclusive result. The person should also not be tested right after an argument, interrogation or long day of work if possible. [hide answer]


THE EXAM ROOM
polytest image 1001 - Do you have an office where I can go for the exam? [view answer]
1001 - In many cases our examiners do provide the exam rooms for the test. Look for any testing location which does NOT have a check mark under the "house" icon (this check mark indicates the test is done only at the customer's location). [hide answer]
polytest image 1002 - What if I am unable to travel to the examiner's office? [view answer]
1002 - Many of our examiners will travel to clients' homes or offices to provide testing, but additional fees will likely apply. It will be the customer's responsibility to provide a suitable room for the exam. Contact us at info@polytest.org for special pricing to come to your location. [hide answer]
polytest image 1003 - If I provide the exam room, what is required? [view answer]
1003 - In some cases it will be the customer's responsibility to provide a suitable testing room. The room must be quiet and free from distracting noises and other interference (ie. crying babies, telephones, television, nearby conversations). Room temperature should be between 70-75 degrees F (21-24 C). No one other than the subject and examiner (and possibly the examiner's assistant or interpreter) are permitted in the exam room. There must be a table (18" x 30" minimum), two chairs and an electrical outlet. This room may be inside someone's home or office, or may be a rented meeting room at a hotel. We do not recommend testing in a hotel room or bedroom, particularly with female subjects, for obvious reasons. [hide answer]
polytest image 1004 - Can I be in the room during someone else’s exam? [view answer]
1004 - No. No person other than the examiner and the examinee are permitted in the exam room during the exam, with a few exceptions. Of course if an interpreter is used that person will have to be in the room. The examiner may have an assistant or second examiner present for training or quality control purposes. In some cases the examinee's attorney may insist on being present during the exam, but this only happens on rare occasions. [hide answer]


TEST RESULTS
polytest image 1101 - How accurate will my test results be? [view answer]
1101 - U.S. Government and American Polygraph Association studies previously concluded that the single-issue (one question) polygraph exam, conducted properly by a qualified examiner, is 87 to 95 percent accurate on average. However, new research has determined that some polygraph techniques are more accurate than others, and has "validated" those techniques which demonstrate a 90% or better accuracy rate for specific issue tests. It is the most accurate tool available today for determining truth or deception. Accuracy of the multi-question exam drops to around 80 percent due to a number of psychological factors. These statistics do not include "inconclusive" results in which no opinion can be made from the polygraph charts, which happens about 5 to 10% of the time. [hide answer]
polytest image 1102 - Who gets the test results? [view answer]
1102 - Test results are usually supplied directly to our client (the person who hired us) and to anyone else specifically designated on the polygraph release form. The person taking the exam is not usually given a copy of the results unless the client authorizes it. Note that the person who paid for the exam may or may not be our client. Simply paying for the exam does not automatically entitle that person to someone else's test results. [hide answer]
polytest image 1103 - How and when do we get the test results? [view answer]
1103 - Release of test results is up to the individual examiner. Some examiners will provide a verbal report immediately, some within 24 hours, and others will provide the written report first and then discuss those results with the client. A written report must be provided by our examiner if the client requests one. This written report can take 7 to 10 days to prepare in some cases. [hide answer]
polytest image 1104 - Are polygraph results confidential? [view answer]
1104 - If your exam is being conducted at the request of an attorney, any information obtained during the course of this examination is covered under attorney privilege and can not be disclosed to anyone outside of this relationship. If privilege is not attached, information obtained during the course of this examination will only be disclosed to our client, or to anyone authorized by our client, with the following exception. Under U.S. Title 18, U.S.C. 4 (Misprision of Felony) if the examinee admits to having committed a felony, we are required to report this information to appropriate authorities. In some U.S. states that require a polygraph license, an examination failure to questions about involvement in a serious crime must also be reported (unless attorney-client privilege is attached). [hide answer]
polytest image 1105 - Is it possible to beat a polygraph? [view answer]
1105 - The polygraph works by recording changes in a person's Sympathetic Nervous System, part of the Autonomic Nervous System, which operates independently of conscious thought. For example, your lungs and heart continue to operate even when you are asleep - you don't have to think about them. These systems can be consciously controlled only very slightly, and attempts to change these systems are usually picked up by the examiners, who are trained to identify such things. It is highly unlikely that someone can alter the outcome of a polygraph exam, but it is not impossible. A verified accuracy rate significantly higher than 90% attests to this fact. Most examiners are now using "countermeasures detection" equipment which easily identifies anyone attempting to use the techniques taught by some web sites and government agencies. Unfortunately, many honest people are found "deceptive" to the test questions after attempting to use these techniques simply because they attempted to influence their test results. When an examiner discovers that the examinee is doing things to affect the charts, the result is either "deception indicated" or "inconclusive." In other words, a person will not pass a polygraph by using these techniques. In fact, recent research (2008-2009) has determined that in most cases when someone attempts to use the techniques taught on the internet to "beat" a polygraph, their test results actually GET WORSE (their scores indicate greater deception than if they had done nothing). Use of certain drugs and medications can also affect the exam, but such use generally results in an "inconclusive" test. It is virtually impossible to change a result from "deceptive" to "truthful" through the use of drugs or medications prior to an exam. If drugs are suspected, a pre-test (or post-test) drug screening is advised. [hide answer]
polytest image 1106 - Can a pathological or compulsive liar beat the polygraph? [view answer]
1106 - No. Compulsive liars may not be able to stop telling lies, but they absolutely know when they are telling a lie. As long as the person being tested knows what reality is, the polygraph will work fine. [hide answer]
polytest image 1107 - What information is usually included in a polygraph report? [view answer]
1107 - A typical polygraph report should include:

(1) the examinee's name
(2) the date of the exam
(3) the purpose of the exam
(4) any relevant statements or admissions made during the exam
(5) the relevant questions that were asked
(6) the answers that were given
(7) the result from the examiner's analysis of the polygraph charts
(8) the examiner's name and signature
(9) the examiner's phone number

The actual charts (polygrams) are not included in the report because significant training is required before they can be understood and/or analyzed.
[hide answer]
polytest image 1108 - What is the difference between a hand score and a computerized score? [view answer]
1108 - A "hand score" is a visual analysis of the polygrams (charts), done by the examiner, following the industry standards and scoring rules for the particular type of polygraph that was given. The computerized score is generated by the computer software and uses complex scoring algorithms. Unfortunately, computers can only look at pure data and often can not determine whether a change in a person's polygram is caused by a psychological reaction rather than a physical distortion (such as a muscle contraction or movement). For this and other reasons, the OFFICIAL score of a polygraph exam is the hand score. The computerized score can be used as supporting information, but not as a stand-alone test result. If you are only provided with a computerized score, you should insist on getting the hand score as well. Some examiners can get lazy and rely only on the computerized score, but a recent survey found that computerized scores disagreed with hand scores 25% of the time. [hide answer]
polytest image 1109 - What do I do once I get the results? [view answer]
1109 - Polygraph is a tool, just like any other. It is designed to assist and guide the investigator or client in making certain decisions. However, since polygraph results are statistical in nature, it is never recommended to make life-changing decisions based solely on the results of a polygraph exam. Results should be used for guidance in making decisions, but should not be the only factor considered when making those decisions. [hide answer]
polytest image 1110 - Are polygraph results admissible in court? [view answer]
1110 - Polygraph results are admissible in many courts, but the final decision usually rests with the individual judge or arbitrator. Civil courts are more likely to admit polygraph evidence than criminal courts. Clients must check with the specific jurisdiction to determine local admissibility standards. If you intend to use polygraph results as evidence, you should select an examiner who has testified and been approved as an "expert." This is noted on our web site by looking for a check mark below the "scales of justice" icon next to the location name. Some judges will require a "Daubert" hearing to determine the admissibility of scientific evidence on a case-by-case basis. As time goes on, more and more jurisdictions are tending toward accepting polygraph evidence.

If the polygraph results are to be used in a legal proceeding, you must use the most accurate and scientifically validated method available. This requires that only a "specific issue" format be used covering one item only per test. Other formats (such as multiple issue tests) do not have the accuracy levels needed to be used as evidence. [hide answer]
polytest image 1111 - Will my GPN examiner testify to support my polygraph results? [view answer]
1111 - Absolutely. All of our examiners will stand behind their test results and will appear at any hearing, trial, or deposition upon request by the client. Note, however, that any fee for testimony is not included in the exam fee. Our examiners do charge for their time, so additional fees will be incurred for testimony. [hide answer]
polytest image 1112 - What does it mean when a polygraph result is inconclusive? [view answer]
1112 - It means that the examiner was not able to render a decision of truth or deception based on the data that was collected. This result is usually caused by the use of certain drugs or medications, lack of sleep, low blood sugar, or the examinee's failure to cooperate with the examiner or to follow instructions. [hide answer]
polytest image 1113 - What if I disagree with a polygraph result from a GPN examiner? [view answer]
1113 - If the results of your GPN exam are in question, or if you would simply like a second opinion, please note that all GPN examiners must provide a complete set of charts (polygrams) from your polygraph upon request so you can have them reviewed by another examiner. These charts will be sent directly to the QC examiner of your choice. Note that a qualified QC examiner must have completed training at an APA-accredited training facility and must be specifically trained in the technique used by your GPN examiner. Your examiner may charge you a reasonable fee for producing these charts. You will be responsible for the cost of the review by the QC examiner that you hire. GPN's owner Michael Martin is available to provide QC services upon request.

A second option would be to have a retest done by a different examiner, but care must be taken to hire a qualified examiner. CLICK HERE to learn how to hire a qualified examiner.
[hide answer]
polytest image 1114 - Can I pay extra to have the test results come out the way I want them to? [view answer]
1114 - Absolutely not. Not only would this be unethical, but it is also illegal in some areas. Do not even ask. We will not do it. [hide answer]


MISCELLANEOUS QUESTIONS
polytest image 1201 - What’s wrong with using Voice Stress Analysis as a lie detection tool? [view answer]
1201 - Not a single published (peer-reviewed) research study - except the studies produced by the VSA equipment manufacturers - gives voice stress technology better than chance odds of determining if someone is being truthful. In other words, flipping a coin gives you the same accuracy. VSA and CVSA proponents will try to tell you about studies that validate their technology, but just ask them for a copy of (or a link to) the actual research and see what you get. CLICK HERE for more information. [hide answer]
polytest image 1202 - Are the polygraph tests I see on television real? [view answer]
1202 - In most cases the polygraph tests you see on television are not real, or they are done by examiners who are not using accepted or validated testing methods. For more information CLICK HERE. [hide answer]
polytest image 1203 - Who sets the industry standards for polygraph? [view answer]
1203 - There are two organizations that have established and published worldwide standards for the administration of polygraph exams – The American Polygraph Association (APA) and the American Society for Testing and Materials (ASTM). All government agencies and courts that have accepted polygraphic evidence require exams to be conducted to certain published standards. If an exam is not done to the standards of at least one of these organizations, the results of that exam can be called into question. Note that simply belonging to one of these organizations does not guarantee that the examiner is conducting exams to their published standards. In addition, make sure the examiner is using a validated testing technique. [hide answer]
polytest image 1204 - Is a law enforcement polygraph the same as a private polygraph? [view answer]
1204 - In a perfect world they would be the same. Unfortunately, many law enforcement examiners use polygraph as an interrogation tool and are more interested in the utility of a polygraph test than in the accuracy of the results. A second issue is that many law enforcement examiners are using out of date (non-validated) testing methods which can lead to incorrect results. Even if the examiner has completed continuing education and has learned the best (most accurate) methods, that examiner must choose (and be allowed to use) those improved methods. The bottom line is that more people fail law enforcement polygraphs than private polygraphs. If you have been asked to take a polygraph by law enforcement, it is often advisable to have a private polygraph done first by a reputable examiner. In many cases law enforcement will accept the results of a private exam if that examiner has acceptable credentials. [hide answer]
polytest image 1205 - Is it possible to rent a polygraph and test someone on my own? [view answer]
1205 - Unless you have completed polygraph school, you will not be able to use a polygraph instrument for the purposes of detecting lies. This requires extensive training and experience. We do rent polygraph equipment, but only for demonstration purposes. CLICK HERE for more information about our rental units. [hide answer]
polytest image 1206 - How can I become a polygraph examiner? [view answer]
1206 - First you must complete an accredited polygraph training program which lasts 10 to 13 weeks. After graduating, you must gain experience by working for an established polygraph company or government agency (as an intern). Once you have achieved some experience, under supervision, and meet any other licensing requirements (which varies by state) you will be able to provide polygraph services on your own. Once you complete at least 250 exams you may be eligible to become a member of the Global Polygraph Network. GPN is now offering an internship program for those examiners who have completed the training but do not yet have the requisite experience. [hide answer]
polytest image 1207 - How can I become a member of the Global Polygraph Network? [view answer]
1207 - If you have completed training at an accredited polygraph training facility you may be eligible to join the Global Polygraph Network. If you have administered over 250 exams you can become a full member and receive polygraph referrals. If you have not administered 250 exams, you may qualify to become an Intern member and must work under the supervision of a full member until you have completed your 250 exams.

polytest image 1210 - How can I beat a polygraph? [view answer]
1210 - Here are the steps necessary to "beat" a polygraph. Keep in mind that these techniques will work less than half the time. Most of the time the examiner will identify that the person is using them.

(1) Get a prescription for a drug that supresses the Sympathetic Nervous System.
(2) Take a course in how to identify the types and purpose of different kinds of questions used in a polygraph exam.
(3) Hire a polygraph examiner to learn how to perform "mental countermeasures." You will have to find an amoral examiner to do this, because a professional examiner will not provide this service. Don't even think about using "physical countermeasures" because all current examiners use sensors to identify physical countermeasures.
(4) Spend a few days with the examiner practicing your countermeasures until you have mastered them.
(5) Hope that the examiner giving you the real test is using the same technique that the practice examiner was using.
(6) Take the medication noted above before the exam.
(7) Cross your fingers.

Note: Being caught using countermeasures is often worse than failing a polygraph because the examiner will never again believe anything you have to say. [hide answer]
polytest image 1211 - What is the problem with using fMRI as a lie detection tool? [view answer]
1211 - fMRI measures blood flow in the brain in real time. In the case of deception, certain parts of the brain are used more ("cognitive overload") with the Subject suppressing memory as they construct a fictitious account of what happened. Unfortunately, the innocent person will also struggle to recall what happened on any particular date and time in the past (unless it just happened), creating the same overload issue as with the deceptive person. There is also the issue of "rehearsal." If the Subject has three weeks to work on his/her story, then cognitive load will be reduced when asked to recall. A well-rehearsed alibi would appear credible while the poor sap who is struggling to remember will appear like the bad guy! At this stage of development, fMRI is much less reliable than polygraph.
