Ensure you use only registered examiners who have the proper training and use registered software (DVSA/FVAS version 4 software is illegal in South Africa)

To all qualified Examiners, if you were issued with the DVSA/FVAS version 4 software contact us to find out how you can upgrade your software to the new Expertosvsa version 6 software.

South Africa has no official standard for VSA Analyzers and the rest of the world does not accept SA qualifications if not on International standard and registered with an International Association.

Due to this loophole there are Instructors presenting their own version of VSA & Polygraph courses with sub-standard or old software claiming false accreditations and therefore not recognized by the International community.


Get a quote for training and ask the Instructor to send you copies of his Instructor's certificates from the training institution he claims membership. Also check if the instructor is still active in the field or have they "retired" from testing.


Welcor TVC is only affiliated with International Associations to maintain the highest possible standards.

WELCOR TVC withdrew from SAPAVSA in 2010.
