We cannot assure that background check shows education, as it is depends on the availability of information . background checks will be done online as well as offline mode. Contacting respected schools and colleges will give information of the candidate education details, joined date, completed date and stream from which he graduated.
All Education records will not be available in public domain to check in social media accounts like linkedin. As a background checking company, we have different key channels to collect information about education, professional experience, criminal check , credit check etc.
