What is a Polygraph Test and How Does it Work?

Legal Considerations and Testing Standards
South African polygraph examiners must follow local laws and ACFE SA standards. Written consent is required before testing anyone.
A typical exam includes pre-assessment, question-answer session, and result analysis. Test duration varies but usually takes 1-3 hours.
