Running a testing center that is used to certify those being tested for specific positions today can require that all test results be submitted online to the state or federal organization. However, you cannot simply email the results in and expect that the appropriate organization is going to accept them as de facto. Today most organizations make use of a two factor authentication system to eliminate any chance that the results could be tampered with.
Verified Results Using Two Factor Authentication
Consider the case of those driver's in the US where you must obtain a federal health examination in order to receive and maintain a CDL or commercial driver's license. If a driver fails, he will no longer be able to drive and without the use of two factor authentication, it would be far too easy for someone to tamper with the results and supply a passing result. To eliminate this risk the government uses the latest in digital certificate technology for all form submissions.
