Dietitian Training

Dietitians and nutritionists need at least a bachelor's degree. Licensure, certification, or registration requirements vary by State.

Education and training. Becoming a dietitian or nutritionist usually requires at least a bachelor's degree in dietetics, foods and nutrition, food service systems management, or a related area. Graduate degrees also are available. College students in these majors take courses in foods, nutrition, institution management, chemistry, biochemistry, biology, microbiology, and physiology. Other suggested courses include business, mathematics, statistics, computer science, psychology, sociology, and economics. High school students interested in becoming a dietitian or nutritionist should take courses in biology, chemistry, mathematics, health, and communications.

As of 2008, there were 279 bachelor's degree programs and 18 master's degree programs approved by the American Dietetic Association's Commission on Accreditation for Dietetics Education.

Licensure. Of the 48 States and jurisdictions with laws governing dietetics, 35 require licensure, 12 require statutory certification, and 1 requires registration. Specific requirements vary by State. As a result, interested candidates should determine the requirements of the State in which they want to work before sitting for any exam.

In States that require licensure, only people who are licensed can work as dietitians and nutritionists. States that require statutory certification limit the use of occupational titles to people who meet certain requirements; individuals without certification can still practice as a dietitian or nutritionist but without using certain titles. Registration is the least restrictive form of State regulation of dietitians and nutritionists. Unregistered people are permitted to practice as a dietitian or nutritionist.

Certification and other qualifications. Although not required, the Commission on Dietetic Registration of the American Dietetic Association awards the Registered Dietitian credential to those who pass an exam after completing academic coursework and a supervised internship. This certification is different from the statutory certification regulated by some States and discussed in the previous section. To maintain a Registered Dietitian status, workers must complete at least 75 credit hours in approved continuing education classes every 5 years.

A supervised internship, required for certification, can be completed in one of two ways. The first requires the completion of a program accredited by the Commission on Dietetic Registration. As of September 2009, there were 51 accredited programs that combined academic and supervised practice experience and generally lasted 4 to 5 years. The second option requires the completion of 900 hours of supervised practice experience in any of the 243 accredited internships. These internships may be full-time programs lasting 6 to 12 months or part-time programs lasting 2 years.

Advancement. Experienced dietitians may advance to management positions, such as assistant director, associate director, or director of a dietetic department, or may become self-employed. Some dietitians specialize in areas such as renal, diabetic, cardiovascular, or pediatric dietetics. Others leave the occupation to become sales representatives for equipment, pharmaceutical, or food manufacturers. A master's degree can help some workers to advance their careers, particularly in career paths related to research, advanced clinical positions, or public health.
