Specialty certification is voluntary recognition by a private board that a nurse has met a standard beyond licensure. It is not licensure, it is not granted by any state, and it does not expand scope of practice.
The exception is advanced practice, where national certification has been written into the regulatory structure and functions as a condition of licensure. See levels of nursing.
These pages cover the credentials themselves — eligibility, renewal, and what each is actually worth. For the bodies that award them, see nursing certification boards. For decoding the letters after a nurse's name, see what the letters after a nurse's name mean. For what the work is in each field, see nursing specialties.

Three things worth knowing before you pay
Check the accreditor. Because this is a private market, nothing prevents an organization from selling a credential with no defensible examination behind it. The recognized accreditors are the Accreditation Board for Specialty Nursing Certification, which is specific to nursing, and the general credentialing accreditor used across professions. Wound care and legal nurse consulting are the two areas where unaccredited credentials are most common.
Check it is still open. Several credentials have closed to new applicants and are maintained by existing holders only — home health nursing, faith community nursing, community health nursing, advanced public health nursing, and several older oncology and clinical nurse specialist credentials among them. The nursing case management credential is closing at the end of 2027. A credential on a colleague's badge may not be available to you.
Check who pays. Many employers cover the examination fee, pay a differential, or fund the continuing education needed to renew. Asking before paying personally is worth the conversation. See clinical ladders.
Renewal is continuing education, and it is not the same as the state's
Certification renewal requirements are set by the certifying board and are separate from the continuing education a state board of nursing requires to renew a licence. The two frequently overlap and are not interchangeable, and hours claimed for one do not automatically count for the other. See continuing education requirements.
What certification does and does not buy
The evidence that certification improves patient outcomes is weaker than the profession's rhetoric implies, because studies cannot separate the credential from the characteristics of nurses who pursue it.
Where it reliably appears is as a structural measure: the proportion of certified nurses on a unit is a nursing-sensitive indicator collected and benchmarked nationally, and it is one of the things Magnet recognition requires an organization to report. That is why employers fund it, and it is a fair reason to expect them to.
