5 Tips For Preparing For A Polygraph Test

Going for a polygraph test doesn’t need to be as challenging as everyone makes it out to be. With sufficient preparation and understanding of the process, you should go into the interview room feeling confident and relaxed.

If you’re feeling overwhelmed by the thought of having to do the polygraph test, you don’t need to be. Let’s take a look at  some helpful tips to assist you with the preparation.

Ensure You Understand The Polygraph Test Process

The polygraph testing machine doesn’t pick up the deceit directly but it rather measures some of physiological changes within your body. The machine measures your heart rate, blood pressure and can also measure your level of perspiration.

It’s also important to note, before the commencement of the test, you’ll be taken through the process, how the equipment works and what the equipment does. To ensure you’re sufficiently prepared, it won’t hurt to do your own research of your own to familiarise yourself with what you can expect.

Do An Enquiry To Establish Which Test Form Will Be Used

When you issued with the questions for the test, be sure to find out which polygraph test form will be used. The Control Quest Test is the most common form used but the Directed Lie Test and Guilty Knowledge Test form can also be used.

If you’re wondering what these tests are, you can expect the following from them:

  • Control Quality Test has control questions mixed into the questions. These Are yes/no questions.
  • Direct Lie Test requires you to directly lie when answering these questions.
  • Guilty Knowledge Test includes multiple choice questions to a variety of facts which only you and the examiner know about.

Go Through Your Test Questions

Within South Africa there aren’t laws that govern using polygraph testing. As no person can be forced to take a polygraph test, your written consent would have been requested. If you agree to take the test, you’ll be issued with all the questions which are being asked within the test.  This serves as a great advantage as it allows you the opportunity to do some preparation before the test ensuring you understand the questions being asked.

Ensure You Disclose Any Medical Conditions

If you suffer from any medical condition or are taking medication like blood pressure medication, you’ll need to inform your examiner of this. As you want the results to be as accurate as possible, by disclosing this information they can factor this in when doing the test with you.

You won’t be disqualified and you won’t fail the test for having a medical condition but it ensures the examiner can conduct the test in the most neutral setting. Asking someone to take a polygraph test can make them feel overwhelmed and nervous.

This is natural and you should be yourself when doing the test. As everyone responds to it differently, if you feeling nervous, this is okay, as long as you speak truthfully and don’t hide anything. The polygraph test isn’t as bad as what its made out to be.
