The certificate is a written document, bureaucratically used to verify an institutionally officiated event. In the process of applying for a job, especially if it is an official institution, certificates are essential to demonstrate training and experience. It is a written document that is normally produced at the request of the person receiving it, and by a person with sufficient authority within the institution to establish that what was stated in the document has been fulfilled. If there is any irregularity or falsehood in what was declared, it may be punished by the law "Sanction (Right)").
