What is Primary Source Verification (PSV)?
PSV is a comprehensive, content-level verification. At QuadraBay (QB), PSV means directly contacting the original issuing authority — for example, a university or educational board — to verify the authenticity of the certificate and its contents such as the dates of attendance, award date, area of study, and other details.
PSV is the gold standard because it goes to the issuing source to validate the authenticity of the certificate itself.
