Professional polygraph testing requires direct supervision by the examiner.
The equipment must be:
Properly installed
Calibrated
Monitored during the examination
The examiner must also:
Observe physical movement
Control the environment
Ensure question timing is accurate
Remote or unsupervised testing does not meet professional standards.
For this reason:
All polygraph examinations are conducted in person
at approved locations that meet professional requirements.
This ensures:
Test integrity
Examiner control
Professional procedure
