To practice as an FNP, you certify through one of two paths: FNP-C (Family Nurse Practitioner-Certified) or FNP-BC (Family Nurse Practitioner-Board Certified). Both credentials are nationally recognized. The difference comes down to the certifying body, the exam, and where the emphasis falls.
Do You Need to Be Certified?
Yes. After you finish a Master of Science in Nursing (MSN) or a Doctor of Nursing Practice (DNP), certification is required to work as an FNP. You can certify through either:
- American Academy of Nurse Practitioners Certification Board (AANP)
- American Nurses Credentialing Center (ANCC)
Once certified, apply for Advanced Practice Registered Nurse (APRN) licensure in your state. Passing the national exam isn't enough on its own; you can't practice legally without a state license. You'll also verify clinical hours, pass a background check, and meet continuing education requirements.
The AANP began in 1985 to support and recognize nurse practitioners nationwide and launched its certification exam in 1991. The ANCC, founded in 1990 under the American Nurses Association, is widely regarded as the gold standard for nurse practitioners, especially those moving into leadership or academic roles.
FNP-C vs. FNP-BC
The AANP administers the FNP-C. Its exam centers on clinical judgment and applied knowledge, with 150 total questions (135 scored, 15 unscored pretest items) built mainly around patient care situations (AANPCB).
The ANCC administers the FNP-BC, which leans more academic. Its exam runs 175 total questions (150 scored, 25 unscored pretest items), with a share focused on healthcare policy, nursing theory, and leadership, and it can include alternate formats like drag-and-drop and hotspot items (ANCC).
The testing styles differ, but the outcome is the same: a competent, safe nurse practitioner qualified to work across healthcare settings.
Is One Better?
No. Both certifications are valid and accepted nationwide. "Both certifications are valid and widely accepted across the country," says Dr. Deborah Hunt, Dean of the College of Nursing at Adelphi University.
Neither exam makes you a better provider. They reflect how you prefer to think and where you're headed. The FNP-C suits clinical decision-making and operational problem solving; the FNP-BC fits leadership or academic tracks. Either way, you'll be licensed to evaluate, diagnose, and prescribe for patients of all ages. The difference is in the test, not the result.
What to Know Before You Certify
First, make sure FNP is the right specialty, rather than psychiatric mental health (PMHNP), pediatric (PNP), or adult-gerontology (AGNP). Then test as soon as you can. Your graduate program prepares you, but study on your own and consider a prep course to improve your odds.
