A Registered Dietitian Nutritionist (RDN) degree requires a master’s degree in nutrition/dietetics from an ACEND-accredited program, completing 1,200+ hours of supervised practice (internship), and passing the Commission on Dietetic Registration (CDR) national examination.
Becoming a Registered Dietitian Nutritionist (RDN) is a rewarding career path that combines scientific expertise with helping people achieve better health through nutrition. The profession has evolved significantly, and as of 2025, all entry-level RDNs must earn a master’s degree to practice.
Per the Academy of Nutrition and Dietetics, RDNs are food and nutrition experts who have met rigorous educational, experiential, and examination standards. They work in diverse settings from hospitals and schools to private practice and corporate wellness programs.

What is an RDN Degree?
An RDN degree is a comprehensive educational pathway that prepares nutrition professionals to provide evidence-based dietary guidance and medical nutrition therapy. The credential demonstrates mastery of food science, nutrition, biochemistry, clinical nutrition, and foodservice management principles.
RDNs are qualified to:
- Provide medical nutrition therapy for patients with diabetes, heart disease, and other chronic conditions
- Develop nutrition programs for hospitals, schools, and community organizations
- Conduct nutrition research and contribute to scientific literature
- Manage foodservice operations in healthcare and institutional settings
- Educate individuals and groups about healthy eating patterns
Master’s Degree Requirement
Starting January 1, 2024, all individuals seeking to become RDNs must complete a minimum of a master’s degree from an ACEND-accredited program. This represents a significant change from previous bachelor’s degree requirements and reflects the profession’s commitment to advanced clinical competency.
The master’s degree requirement ensures RDNs have:
- Advanced clinical knowledge for complex medical nutrition therapy
- Research skills to evaluate and apply emerging nutrition science
- Leadership abilities for healthcare team collaboration
- Specialized expertise in focus areas like pediatric or sports nutrition

ACEND Accreditation Requirements
The Accreditation Council for Education in Nutrition and Dietetics (ACEND) is the sole accrediting body for RDN education programs. Any degree program you choose must hold current ACEND accreditation to qualify for the dietetic internship and CDR examination.
ACEND accreditation ensures programs meet strict standards for:
- Faculty qualifications and student-to-faculty ratios
- Curriculum depth covering all required knowledge areas
- Laboratory facilities and learning resources
- Student outcomes, including CDR exam pass rates
- Continuous quality improvement processes
CP vs DPD Program Comparison
ACEND accredits two types of master’s degree programs for aspiring RDNs. Understanding the difference helps you choose the best path for your career goals:
| Program Type | Education Structure | Internship | Timeline | Best For |
|---|---|---|---|---|
| Coordinated Program (CP) | Master’s coursework + internship combined | Integrated throughout the program | 2-3 years total | Streamlined path, guaranteed internship placement |
| Didactic Program in Dietetics (DPD) | Master’s coursework only | Separate competitive application | 3-4 years total | Flexibility, geographic preferences |
Coordinated Program (CP) Details
CPs offer a comprehensive educational experience combining classroom learning with supervised practice. Students complete both academic requirements and the 1,200+ hour internship within a single program. Upon graduation, CP students are immediately eligible for the CDR examination.
Didactic Program in Dietetics (DPD) Details
DPD programs focus on academic coursework and theoretical knowledge. After completing the master’s degree, graduates must separately apply for and complete an accredited dietetic internship before becoming eligible for the CDR exam. This path offers more flexibility in timing and internship location.
Dietetic Internship Requirements
All future RDNs must complete a minimum of 1,200 hours of supervised practice training. This hands-on experience occurs in diverse settings to ensure comprehensive competency development:
Core Rotation Areas
- Clinical Dietetics – Patient care in hospitals and medical centers
- Food Service Management – Large-scale food production and service
- Community Nutrition – Public health and wellness programs
- Specialty Rotations – Pediatrics, sports nutrition, or research focus
During internships, students develop practical skills in patient assessment, menu planning, nutrition education, and foodservice operations under the guidance of experienced RDN preceptors.
CDR National Examination
The Commission on Dietetic Registration (CDR) examination is the final step to earning RDN credentials. This computer-based exam tests knowledge across four key domains:
- Principles of Dietetics (15% of exam)
- Nutrition Care for Individuals and Groups (40% of exam)
- Management of Food and Nutrition Programs (25% of exam)
- Foodservice Systems (20% of exam)
The CDR exam has a national pass rate of approximately 85-90% for first-time test takers from accredited programs. Most states also require RDNs to obtain professional licensure for practice.
Career Outcomes and Salary
According to the Bureau of Labor Statistics (BLS), RDNs earned a median salary of $65,620 as of May 2023. However, earnings vary significantly by setting and specialization:
| Work Setting | Median Annual Salary | Job Growth Outlook |
|---|---|---|
| Hospitals | $67,840 | 7% (faster than average) |
| Outpatient Care Centers | $71,230 | 8% (faster than average) |
| Government | $74,770 | 6% (as fast as average) |
| Private Practice | Varies widely by region and business model | 6% (faster than average) |
The BLS projects 7.4% job growth for dietitians and nutritionists between 2023-2033, much faster than the 4% average for all occupations. This growth reflects increased awareness of nutrition’s role in preventing chronic diseases.
Specialization Opportunities
RDNs can pursue additional certifications in specialized areas:
- Certified Diabetes Care and Education Specialist (CDCES)
- Certified Specialist in Sports Dietetics (CSSD)
- Certified Nutrition Support Clinician (CNSC)
- Board Certified Specialist in Pediatric Nutrition (CSP)
