A Personnel Certification Body is an organization that awards credentials to individuals meeting specific competence requirements relating to a profession, an occupation, a job or a portion of a job. A personnel certification body develops criteria against which an individual needs to demonstrate competencies and ensures that applicants hold these criteria before certifying them.

Most personnel certification bodies offer professional certification if an individual meets requirements such as a minimum number of years of related working experience, minimum education level and having passed a certification exam or equivalent.
