Overview of the FNP Certification
The Family Nurse Practitioner (FNP) certification qualifies registered nurses to practice as
advanced practice registered nurses (APRNs) who provide primary care across the lifespan
—from pediatrics to geriatrics. The FNP functions autonomously and collaboratively within the
healthcare system to assess, diagnose, treat, and manage acute and chronic health conditions
while promoting health and disease prevention.
Two certifying bodies offer FNP credentials in the U.S.:
AANP Certification Board (AANPCB) – Awards the FNP-C (Certified Family Nurse
Practitioner) credential.
ANCC (American Nurses Credentialing Center) – Awards the FNP-BC (Board
Certified Family Nurse Practitioner) credential.
Both certifications are nationally recognized and similar in scope but differ slightly in exam
format, content focus, and renewal requirements.
