Steps to become a registered dietitian at OHSU

Step 1: Complete a Didactic Program in Dietetics (DPD)

To become an RD, start by completing a DPD at an institution accredited through the Accreditation Council for Education in Nutrition and Dietetics (ACEND). A DPD is a set of undergraduate or graduate courses that prepare you for supervised practice.  

Find a DPD near you.

Step 2: Earn a graduate degree and complete supervised practice through an OHSU program

After you finish a DPD, you must earn a graduate degree and complete supervised practice through an ACEND-accredited program.

You have two options at OHSU:

Step 3: Pass the registration exam (RD exam) for dietitians through the Commission on Dietetic Registration (CDR)

This national exam is required to earn your RD credential.

It covers:

  • Clinical nutrition
  • Food service systems
  • Community nutrition
  • Professional practice

Step 4: Get licensed if your state requires it

Some states require RDs to get a license to practice. 

In Oregon, you need to be licensed through the Oregon Health Licensing Office. This requires passing the RD exam and meeting education and training requirements. 

Step 5: Maintain your RD certification

To stay certified, complete continuing education every five years. The Commission on Dietetic Registration provides guidelines for ongoing professional development.
