What is an audit certificate?
According to ISO 19011, audit evidence refers to “records, findings, or other information that is relevant to the audit criteria and verifiable.” The Guidance on Auditing Management Systems requires that audit evidence be objective. Audit evidence can be qualitative or quantitative. If a statement is made to an auditor (e.g., regular employee reviews), audit evidence (e.g., meeting minutes) is required to substantiate that claim.
