RDNs hold an undergraduate degree. They have completed an approved internship program and have passed a national exam. This allows them to be credentialed as registered dietitian nutritionists. Many have also earned a master's degree in dietetics, public health, or nutrition science. Beginning in 2024, a graduate degree will be the minimum degree requirement for people wanting to become RDNs.
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.
