Registered Dietitian

Registered Dietitian

Registered Dietitians (RDs) are the food and nutrition experts who can translate the science behind nutrition into practical solutions for healthy living. As experts in the field of nutrition, Registered Dietitians create dietary modifications for disease prevention, treatment, and improvement of overall health.

Registered Dieticians use their nutrition expertise to

  • Help develop and implement an individualized care plan
  • Promote the patient’s understanding and management of their condition
  • Optimize quality of life
  • Improve clinical outcomes

Effective January 1, 2024, a master’s degree is required to take the exam to become an RD

Registered Dietitian Prerequisites

NOTE: Specific prerequisite courses can vary by school--always double-check the website of each program you are applying to for specific requirements. Please review the CSUSB Catalog as a guide to completing the CSUSB prerequisites.

Though some coursework is only needed for one semester, do keep in mind the courses can be sequential, meaning you have to complete two semesters' worth of courses in order to advance to the next prerequisite. (For example: CHEM 2200 is a semester prerequisite for CHEM 2400)

How do I become a Registered Dietitian?

  • Step 1: Earn a Bachelor's or Master of Science degree in Nutrition and Dietetics from an institution that is accredited by the Accreditation Council for Education in Nutrition and Dietetics 
  • Step 2: Completion of a Dietetic Internship (DI) to gain experience in the field 
    • Usually 1000 - 1200 hours
    • Can only be matched with a DI after earning a Bachelor's/Masters degree in nutrition
  • Step 3: Take the Commission on Dietetic Registration (CDR) Exam
    • You have one year from your date of eligibility status to schedule and take the exam
  • Step 4: Gain licensure in your state of practice (note that California does not have licensure for RD/RDNs at this time)
  • Step 5: Maintain continuing professional education
    • Every five years, your registration through the Commission on Dietetic Registration (CDR)  will come up for renewal.

Are there different types of Dietitians?
