To become a registered dietitian in Oklahoma, you need a master’s degree from an ACEND-accredited program, complete 1,000 hours of supervised practice through a dietetic internship, pass the CDR exam, and obtain state licensure from the Oklahoma Medical Board. The complete process takes 6-8 years, and RDs in Oklahoma earn an average salary of $65,810 as of May 2024.
Oklahoma’s growing healthcare sector and increasing focus on preventive medicine have created strong demand for qualified nutrition professionals. According to the Commission on Dietetic Registration, there were 1,195 Registered Dietitians (RDs) and Registered Dietitian Nutritionists (RDNs) in Oklahoma as of June 2025. This represents steady growth in the profession across the state.
The Bureau of Labor Statistics reports that dietitians and nutritionists in Oklahoma earned an average salary of $65,810 as of May 2024 (the most recent annual data available). Entry-level professionals earned about $59,130, while experienced dietitians earned $83,160 or more. With Oklahoma’s affordable cost of living and expanding healthcare opportunities, becoming a registered dietitian offers both professional fulfillment and financial stability.
The Oklahoma Medical Board’s Committee for Licensed and Professional Dietitians defines the scope of practice for RDs as professionals who “apply and integrate scientific principles of nutrition pursuant to different health, social, cultural, physical, psychological, and economic conditions to the proper nourishment, care, and education of individuals or groups throughout life.”

The Accreditation Council for Education in Nutrition and Dietetics (ACEND) oversees program quality and ensures graduates meet national competency standards. Oklahoma offers two types of ACEND-accredited programs that fulfill these requirements.
Types of ACEND-Accredited Programs
To meet Oklahoma’s licensure requirements, you must complete either:
| Program Type | Description | What You Need After |
|---|---|---|
| Coordinated Program (CP) | Combines graduate coursework with 1,000 hours of supervised practice in one integrated program | Nothing – immediately eligible for CDR exam |
| Didactic Program (DPD) | Coursework only at bachelor’s or master’s level | Must complete master’s degree (if bachelor’s DPD) + separate dietetic internship (1,000 hours) |
ACEND-Accredited Programs in Oklahoma
Master’s Level Didactic Programs
Oklahoma offers one master ‘s-level DPD program. After completing this program, you must apply separately for a dietetic internship to fulfill the supervised practice requirement.
University of Oklahoma Health Sciences Center, Oklahoma City
Master of Arts in Dietetics (Didactic Program)
After graduation, you must complete a separate dietetic internship before taking the CDR exam
Bachelor’s Level Didactic Programs
Oklahoma has three bachelor-level DPD programs. Important: Completing a bachelor’s DPD is only the first step. You must then complete both a master’s degree program and a dietetic internship before you’re eligible for the CDR exam.
University of Central Oklahoma, Edmond
Bachelor of Science in Nutrition, Dietetics, and Food Management
After graduation: Master’s degree required + dietetic internship required
Oklahoma State University, Stillwater
Bachelor of Science in Nutritional Sciences (Dietetics concentration)
After graduation: Master’s degree required + dietetic internship required
Northeastern State University, Tahlequah
Bachelor of Science in Nutritional Sciences (Dietetics concentration)

Note: Oklahoma does not currently have any ACEND-accredited Coordinated Programs that integrate coursework with supervised practice at the graduate level. All Oklahoma students must complete a separate dietetic internship after their degree program.
Timeline to Become an RD in Oklahoma
The complete path to becoming a registered dietitian in Oklahoma requires multiple sequential steps:
| Education Stage | Duration | Total Time Elapsed |
|---|---|---|
| Bachelor’s Degree (DPD) | 4 years full-time | 4 years |
| Master’s Degree | 1-2 years | 5-6 years |
| Dietetic Internship | 8-16 months | 6-7+ years |
| CDR Exam + Licensure | 2-4 months | 6-8 years total |
Total Time: Expect 6-8 years from starting your bachelor’s degree to becoming a fully licensed RD in Oklahoma. This assumes full-time enrollment and no breaks between programs.
Important Note: Unlike some states, Oklahoma does not currently offer graduate-level Coordinated Programs that combine coursework with supervised practice. All Oklahoma students must complete their degree(s) first, then apply separately for a dietetic internship.
National Online Nutrition Programs
While completing your education, you may also consider national online programs. These programs can provide additional nutrition knowledge but do not replace ACEND-accredited requirements for RD eligibility. The following programs offer career-focused instruction:
Apply for Your Dietetic Internship (DI) in Oklahoma
If you completed a didactic program in dietetics (DPD) rather than a coordinated program, you must apply for and complete a dietetic internship to fulfill the supervised practice requirement. As of January 1, 2024, all RD candidates are required to complete 1,000 hours of supervised practice.
Dietetic internships are competitive, and acceptance rates vary by program. The application process typically occurs through D&D Digital (formerly DICAS), the centralized application system for dietetic internships.
Dietetic Internships in Oklahoma
Oklahoma offers four ACEND-accredited dietetic internship programs with different specializations and formats:
| Program | Location | Format | Duration | Emphasis Area |
|---|---|---|---|---|

| Keith & Associates Distance Dietetic Internship | Tulsa (distance option) | Full-time or part-time | 8 months (FT) or 16 months (PT) | Business and entrepreneurship |
Application Tips for Dietetic Internships
Competition for internship positions can be intense. Strengthen your application by:
- Maintaining a strong GPA (3.0 or higher recommended)
- Gaining relevant volunteer or work experience in nutrition settings
- Securing strong letters of recommendation from faculty or professionals
- Tailoring your personal statement to each program’s emphasis area
- Applying to multiple programs to increase acceptance chances
Most programs have application deadlines in February or March for internships beginning the following summer or fall. Plan ahead and prepare materials several months in advance.
Pass the Commission on Dietetic Registration Examination
Before you can apply for state licensure in Oklahoma, you must pass the National Commission on Dietetic Registration (CDR) exam. This computer-based examination tests your knowledge across all domains of dietetics practice.
CDR Exam Eligibility and Registration
Once you complete your coordinated program or dietetic internship, your program director will verify your eligibility with the CDR. You’ll receive an email with instructions to:
- Register for the examination online
- Pay the $200 examination fee
- Schedule your test date and location
You have 365 days from receiving your eligibility email to register, schedule, and complete the exam. Don’t wait until the last minute – give yourself adequate preparation time.
CDR Exam Format and Content
The CDR examination includes 125-145 multiple-choice questions covering four domains:
| Domain | Percentage of Exam | Focus Areas |
|---|---|---|
| Principles of Dietetics | 25% | Professional standards, ethics, research principles |
| Nutrition Care for Individuals and Groups | 40% | Medical nutrition therapy, counseling, care planning |
| Management of Food and Nutrition Programs | 21% | Program planning, quality improvement, leadership |
| Foodservice Systems | 14% | Menu planning, food safety, procurement, sustainability |
The exam includes 25 pretest questions that don’t count toward your score but help CDR develop future exams. You’ll have 3 hours (180 minutes) to complete all questions.
Preparing for the CDR Exam
The Commission on Dietetic Registration provides two essential study resources:
- Comprehensive Study Outline and Study Guide – Details all content areas covered on the exam
- Registration Examination for Dietitians Handbook – Explains exam format, policies, and procedures
Many candidates also use commercial study guides, practice exams, and study groups to prepare. Plan for at least 4-6 weeks of focused study time.
Taking the Exam in Oklahoma
The CDR exam is administered through Pearson VUE testing centers. Oklahoma has testing centers in:
- Norman
- Oklahoma City
- Tulsa
On exam day, bring your government-issued photo ID and your Pearson VUE confirmation email. The testing center provides a basic calculator and scratch paper. Personal items must be stored in a locker.
Scoring and Results
The CDR exam uses a scaled scoring system ranging from 1 to 50. You need a minimum scaled score of 25 to pass. This is not a direct count of correct answers but rather a standardized score that accounts for question difficulty and ensures consistent passing standards across different exam versions.
You’ll receive preliminary results immediately after completing the exam, with official results posted to your CDR account within a few days.
If you don’t pass on your first attempt, you must wait 45 days before retaking the test. To reauthorize for another exam, contact the CDR through their website at cdrnet.org or call (312) 899-4859.

Oklahoma does not currently offer graduate-level Coordinated Programs that integrate coursework with supervised practice; therefore, all students must complete a separate internship after completing their degree.

In Oklahoma, the title “registered dietitian” is legally protected and requires state licensure.

Only licensed RDs can provide medical nutrition therapy and work in clinical settings. Learn more about the differences between nutritionists and dietitians.

Can I complete my dietetic internship in another state and still get licensed in Oklahoma?
Yes. As long as your dietetic internship is ACEND-accredited, you can complete it anywhere in the United States and still qualify for Oklahoma licensure. Many candidates complete internships out of state, especially if they’re accepted into competitive programs or those with specialized focus areas that align with their career goals.
