According to The Guide to National Professional Certification Programs (1997) by Phillip Barnhart, "certifications are portable, since they do not depend on one company's definition of a certain job" and they provide potential employers with "an impartial, third-party endorsement of an individual's professional knowledge and experience".
Certification is different from professional licensure. In the United States, licenses are typically issued by state agencies, whereas certifications are usually awarded by professional societies or educational institutes. Obtaining a certificate is voluntary in some fields, but in others, certification from a government-accredited agency may be legally required to perform certain jobs or tasks. In other countries, licenses are typically granted by professional societies or universities and require a certificate after about three to five years and so on thereafter. The assessment process for certification may be more comprehensive than that of licensure, though sometimes the assessment process is very similar or even the same, despite differing in terms of legal status.
