The standards put forth by the American Dietetic Association and the Iowa Department of Public Health for nutritionists and dietitians were created for multiple reasons:

  1. To protect the residents of Iowa as patients and clients of nutrition professionals, ensuring their safety and the excellence of care that they receive;
  2. To maintain the standards in the field of nutrition, including all of those who use the term registered dietitian or dietetic technician, registered;
  3. To ensure a close community of nutrition and dietetic professionals who endeavor to work together to continually improve research, practice methods and skills in the industry.

The Iowa Department of Public Health and the Iowa Dietetic Association require that all dietitians and dietetic technicians are registered with the Commission on Dietetic Registration (CDR), the American Dietetic Association’s official licensing body. Iowa does not specifically require a state examination and registration process, instead recognizing the national certification process of the CDR.

Certification to become a registered dietitian (RD) or dietetic technician, registered (DTR) by the CDR and the HDA are as follows:

  1. Completion of an acceptable four-year degree or higher focused on nutrition science, dietetics or closely related field
  2. Completion of the CDR's registration examination for dietitians
  3. Registration with the Iowa Department of Public Health’s Board of Licensing
