About Our Company

The Polygraph Academy was established in 2015 by Trevor Henn and Deon Groenewald, Directors of the Academy, to ensure ethical administration and interpretation of polygraph examinations in Africa, rooted in the APA accredited programs and focused on South African and African requirements and unique needs.

Previously, all training in South Africa was done primarily by APA registered providers from the United States and once before 1998 by an Israeli school. Our affordable, quality programs are designed to serve South African and African needs while based on international content.

The Polygraph Academy offers internationally aligned South African and African focussed comprehensive training solutions in the field of Polygraph Examinations and detection of deception. Programs are presented by experienced South African Polygraph Specialists and subject matter experts. Students are educated in theory and practice, trained, coached and mentored to become competent Polygraph Examiners/ Forensic Psychophysiologists.

Theory is followed by application under quality supervision until students are certified competent. Proficiency is facilitated through accountable quality assurance.

The first South African Polygraph Examiner program was presented in Pretoria from 12 January 2016. We have trained 47 Polygraph Examiners up to 2019. Our graduates operate in South Africa, Namibia, Eswatini, Congo, Botswana and Nigeria.

Our graduates are allowed to become members of the Polygraph Examiners Association International (PEAI) who has also recognised the Polygraph Academy as training Institution as well as the International Society of Polygraph Examiners (ISOPE) and the British and European Polygraph Association (BEPA).
