Important Information


You would think that of all the professionals, polygraph (lie detector) examiners would value truth more than most people. And most of us do. However…

Some people pretending to be polygraph examiners are outright frauds and confidence trick merchants.
Hundreds of people each year in the UK are falling prey to these so-called examiners and yet you get nothing in return for your hard-earned money.


Forewarned is forearmed – don’t fall victim to some of the scams offered out there. There are several steps you can take before selecting your examiner:

1. Verify the examiner’s primary polygraph training by asking which polygraph school they attended. Most polygraph schools will verify graduates over the phone. Then, check with the American Polygraph Association APA  ( or the British and European Polygraph Association BEPA ( to verify the school is (or was) accredited.

2. Be very suspicious of examiners who do not belong to one of the above mentioned organisations.
If the examiner claims such a membership, this can be verified by contacting the organisation directly.
The British Polygraph Network only uses fully qualified examiners who are members of both the APA and the BEPA.

3. Verify that the examiner is fully qualified by asking to see his/her qualifications at the time of the test.

4. Ask to see the examiner’s Curriculum Vitae or resume if you are unsure in anyway.
ALL BPN examiners have been thoroughly vetted in advance with everyone including their references, backgrounds and qualifications checked.

5. Please also ensure that your examiner is registered with the Information Commissioners Office as this ensures that any data from your test remains highly confidential.
ALL BPN Examiners are ICO compliant.

6. Be cautious of any examiner charging significantly less than the average price for your area or charges extras after the test.
The BPN does not have any hidden charges whatsoever.

7. If the examiner offers you a polygraph lie detection service which can be conducted “over the phone” you’re about to be scammed.

8. A polygraph examiner may have been qualified for many years but polygraph technology and techniques change frequently, so unless the examiner regularly attends continuing education courses he/she may not be using up-to-date methods. Ask them whether they have maintained their Continuous Professional Development hours up which are required by both the APA and the BEPA.
All BPN examiners DO maintain at least 30 hours every two years of approved additional training.

9. Only trust an examiner using computerised system polygraph equipment as opposed to the old fashioned analogue type.
Please note all our BPN examiners use the latest computerised system and techniques to ensure highest possible accuracy.

10. If the exam has already been conducted, make sure the exam took 90 minutes or longer and that no more than 4 relevant questions were asked.
ALL our examinations comply with APA & BEPA testing protocols and procedures.

11. If the exam has already been conducted, you should receive a written report which should include the examiner’s name, address, phone number, signature, name of the examinee, date of the exam, the purpose of the exam, the list of relevant questions asked and answers given, and the analysis of those answers. Beware of any examiner who uses the expressions “Truth” or “Truthfulness” in their report as this is not typical terminology that is used in a polygraph report.

12. Ask whether the examiner is having their work quality controlled by another independent texaminer.
BPN examiners submit all their tests for independent verification before results are given to clients.
