FAQs

Yes, as a fully qualified Polygraph Examiner trained at the Marston Polygraph Academy in San Bernadino, California, Premier Polygraph Services are Members of the British & European Polygraph Association and The European Polygraph Association. 

A test will normally last between 1.5 and 2 hours and is made up of three sections. The pre-test interview, the test itself and the post-test discussion.

The answer does depend on a number of factors that your examiner will talk through with you. In most case the accuracy level will vary from 80%-95%.

When you take a test with us, you will be given your results straight after the test. These will be verbal to begin with, with a written report 24 hours later.

In most cases your prescribed medication will not affect the results of a test? Once your examiner knows what you are taking, they will be able to give you a definite answer.

The short answer is yes, you will be asked not to take any recreational drugs in the 24 hours before a Polygraph test.

This is a bit of a long-winded answer. Yes, a polygraph test can be beaten, however you really need to know what you are doing. In truth a lot of people try beat a Polygraph test, if you read some of the online material, they make it sound like the simplest thing on earth to do. In reality it just isn’t that easy. The only way someone will beat a test is if they are trained by a qualified examiner and even then they only have 50% chance of getting right.

Every person I’ve ever tested has been nervous. During the pre-test interview we will spend quite a bit of time talking about what will happen during the test and what you can expect tofeel. We will also do an “acquaintance test” or practice test to give you a chance to really get comfortable with the process. This “practice test” will give me a chance to gauge how nervous you are and if it is likely to affect the results. Never agree to do a Polygraph test without doing an acquaintance test first.

As much as possible we try stick to three or four questions per test. It is accurate to say you can ask as many questions as you like, however you will require more than one test if you want to ask more than the standard number. You would therefore be expected to pay more. In 95% of cases 3/4 questions is enough to get to the bottom of most problems.

No and no. Any Polygraph test needs to be made up of a number of different questions. All the questions serve a purpose during the test and should never be missed out.

No, it takes a great deal of training to be able to ask questions during a polygraph test.

No, during any test I want to be as fair as possible to the person being tested and allow them to take a test with no distractions. It’s also a standard requirement that no one else is in the room.

No, you and the examiner will contract and agree all the question before the test starts. A qualified examiner will never ask a trick or surprise question. If this does happen to you, you should stop the test immediately.

This is really important, inconclusive means the person being tested is not guilty of whatever they have been accused of. It simply means we were not able to tell if they telling the truth or not. It’s not the same as a fail.
