Certification refers to the confirmation of certain characteristics of an object, person, or organization. One of the most common types of certification is professional certification, where a person is certified as being able to competently complete a job or task, usually by passing of an examination/test.

Certification is not licensure which is administered by a governmental entity for public protection purposes and certification by a professional association. However, they are similar in that they both require the demonstration of a certain level of knowledge, skill and ability. The competence of a Certification body is assessed for a particular discipline for accreditation by a National Authority.

Qualification is historical fact but Certification with validity period reflects the current state of knowledge and skill.
