National Certified Nurses Day is celebrated annually on March 19 to honor nurses who have gone beyond their basic license and earned national board certification in a specialty. That might mean critical care, emergency medicine, pediatrics, oncology, or dozens of other fields — each with its own rigorous exam and continuing-education requirements.

The date of the observance itself carries special significance. March 19 is the birthday of Margretta “Gretta” Madden Styles, an international pioneer in nursing credentialing who designed the first comprehensive study of nurse certification. The day was co-founded by the American Nurses Credentialing Center (ANCC) and the American Nurses Association (ANA), and it has been observed since 2008.

What Makes Certification Special?

Board certification is voluntary, which makes it meaningful. Certified nurses have chosen to validate their expertise through standardized testing and ongoing professional development. Research consistently links certified nursing staff to better patient outcomes and higher standards of care. If you notice initials like “BC” (Board Certified), “CCRN,” or “CEN” on a nurse’s badge, those letters represent hundreds of hours of advanced study.
