How a Polygraph Examination Works

  1. Initial consultation
    We discuss your situation, whether a polygraph examination is appropriate, and who should be tested.
  2. Case background
    You share the relevant background information so the examination can be prepared appropriately.
  3. Pre-test interview
    Before the examination begins, the examiner explains the process, outlines the subject's rights, and provides an opportunity for any voluntary disclosures.
  4. Examination
    The polygraph test is conducted privately and professionally under controlled conditions.
  5. Report and feedback
    A professional report is prepared and the results are discussed with you where required.

Polygraph & Truth Verification Services exclusively makes use of Lafayette polygraph technology, developed in the United States and internationally recognised as a leader in professional polygraph instrumentation.
