As of 2024, a graduate degree is the minimum degree requirement to become an RDN. RDNs must have also completed an approved internship program and have passed a national exam. This allows them to be credentialed as registered dietitian nutritionists.
RDNs must complete ongoing professional educational requirements to keep their registration. Some RDNs also hold other certifications in special areas of practice. These include diabetes care and education, sports dietetics, nutrition support, and oncology, pediatric, or renal nutrition.
