Accreditation is synonymous with both quality and competence of an organization, based on international standard(s). Accreditation refers to recognition given to an organization by an authoritative. It is a process by which an authoritative body gives formal recognition that a Conformity Assessment Body (CAB) fulfills specified requirements and is competent to carry out specific tasks.
Accreditation is the most appropriate way to ensure an organization’s competence to perform a specified task. By encompassing the human element of the CAB, end-users can be sure that their data is accurate and dependable.
