Booking Through Us vs. Finding an Examiner on Your Own

On your own

  • You must confirm the training school is genuinely APA-accredited — many “certificates” come from unaccredited courses.
  • You must check that memberships are real and have not lapsed.
  • You must verify the state licence with the Tennessee Polygraph Commission yourself.
  • Few people think to ask about professional liability insurance.
  • A sole operator often has no published standards and no complaints route.
  • You may pay in full for a test your situation is not suitable for.
