Does a nutrition degree give you a certification?
No. A nutrition degree and a professional credential are separate. RDN exam eligibility requires a graduate degree plus the applicable ACEND-accredited coursework and supervised practice. A nutrition master’s that does not meet those pathway requirements does not establish eligibility.
Professional eligibility depends on the accredited pathway and credential requirements, not the degree title alone. Clinical employers, state licensure boards and insurers may require a specific credential. This site indexes 62 online nutrition programs across 51institutions. Their federal subject codes can organize a search, but those codes do not establish ACEND accreditation or RDN-exam eligibility. Verify the exact degree in ACEND’s directory before treating it as a professional route.
Identify the credential required for your target role, then verify which programs provide the appropriate accredited pathway.
Issuing body and entry level
What nutrition certifications are there?
Two boards issue the credentials that matter in nutrition and dietetics. The Commission on Dietetic Registration issues 7 of the 8 below, including all five board specialties, and the Board for Certification of Nutrition Specialists issues the CNS. Entry level is the degree you must already hold before the exam is open to you.
| Credential | Issued by | Entry level | What it takes |
|---|---|---|---|
| RDNRegistered Dietitian Nutritionist | CDR | Graduate degree | A graduate degree, an ACEND-accredited pathway including supervised practice, then the CDR registration examination for dietitians. |
| NDTRNutrition and Dietetics Technician, Registered | CDR | Associate degree | An associate degree through an ACEND-accredited dietetic technician program including supervised practice, then the CDR registration examination for dietetic technicians. |
| CNSCertified Nutrition Specialist | BCNS | Graduate degree | A master’s or doctoral degree in nutrition or a clinical healthcare field, supervised practice experience, then the CNS examination. |
| CSSDBoard Certified Specialist in Sports Dietetics | CDR | Current RDN | Documented practice in sports dietetics, then the CDR specialty examination. |
| CSPBoard Certified Specialist in Pediatric Nutrition | CDR | Current RDN | Documented practice in pediatric nutrition, then the CDR specialty examination. |
| CSOBoard Certified Specialist in Oncology Nutrition | CDR | Current RDN | Documented practice in oncology nutrition, then the CDR specialty examination. |
| CSRBoard Certified Specialist in Renal Nutrition | CDR | Current RDN | Documented practice in renal nutrition, then the CDR specialty examination. |
| CSGBoard Certified Specialist in Gerontological Nutrition | CDR | Current RDN | Documented practice in gerontological nutrition, then the CDR specialty examination. |
CDR is the Commission on Dietetic Registration. BCNS is the Board for Certification of Nutrition Specialists.
Which nutrition certification should you go for?
Compare the RDN and NDTR by education level, scope of practice and common work settings. Both are issued by the Commission on Dietetic Registration but have different requirements.
Commission on Dietetic Registration
RDN, Registered Dietitian Nutritionist
The clinical credential, and the one hospitals, dialysis units and long-term care employers ask for by name. Since 1 January 2024 you need a graduate degree to sit the exam, plus an ACEND-accredited pathway and supervised practice hours you complete in person.

Commission on Dietetic Registration
NDTR, Nutrition and Dietetics Technician, Registered
This technician credential can begin with an eligible associate-level pathway. NDTRs work in clinical, community and foodservice settings, often alongside an RDN. Of the 5 online associate programs indexed here, 1 is filed under the dietetic technician code, so most people reach this credential on campus.

The CNS is the third credential a career changer runs into, and it sits outside the CDR system entirely. It comes from the Board for Certification of Nutrition Specialists, it starts from a master’s or doctoral degree in nutrition or a clinical healthcare field, and it has its own supervised practice requirement and its own exam.
What are the CDR board specialty certifications?
They are not an alternative to the RDN. They stack on top of it. Every one of the 5 below requires you to hold a current RDN first, then document practice in the specialty, then pass a separate CDR examination for that area. So a specialty is a mid-career move rather than a way in, and none of them is something you choose between programs over.
These specialty certifications cover distinct practice areas such as pediatric, renal and oncology nutrition.
- CSSDBoard Certified Specialist in Sports DieteticsDocumented practice in sports dietetics, then the CDR specialty examination.
- CSPBoard Certified Specialist in Pediatric NutritionDocumented practice in pediatric nutrition, then the CDR specialty examination.
- CSOBoard Certified Specialist in Oncology NutritionDocumented practice in oncology nutrition, then the CDR specialty examination.
- CSRBoard Certified Specialist in Renal NutritionDocumented practice in renal nutrition, then the CDR specialty examination.
- CSGBoard Certified Specialist in Gerontological NutritionDocumented practice in gerontological nutrition, then the CDR specialty examination.
Nutrition credential and licensure requirements
Is nutritionist a protected title?
In most states, “nutritionist” is not a protected title. State laws vary on who may provide medical nutrition therapy, bill insurance or use a licensed title such as licensed dietitian.
RDN and NDTR are credentials issued by the Commission on Dietetic Registration. They require specific education, supervised practice or work experience, an exam and current registration. CDR board specialty certifications require a current RDN plus additional specialty experience and an exam.
Hospitals, dialysis clinics, long-term care facilities and employers that bill insurance commonly require the RDN. Private wellness coaching may have different requirements. Check the relevant state licensure board before enrolling to confirm which services and titles the law permits where you plan to work.
What do dietitians and nutritionists earn?
The national median is $76,400 across 77,570 people employed in the occupation, in the BLS Occupational Employment and Wage Statistics release of May 2025. A median is a midpoint, not an offer, so read the spread with it: the middle half earn between $63,080 and $89,340, the tenth percentile is $49,090 and the ninetieth is $103,720, a range of $54,630 from one end of the occupation to the other.
Those are figures for everyone the survey counts under dietitians and nutritionists, credentialed and not, at every stage of a career. They are not a starting salary and they are not attached to any one certification on this page.

Questions about nutrition certifications
What is the difference between an RDN and a nutritionist?
The RDN is a credential awarded by the Commission on Dietetic Registration. It requires a graduate degree, ACEND-accredited education, supervised practice and a passing exam score. “Nutritionist” is a broader job title that is not protected in most states, although state laws may restrict who can provide medical nutrition therapy or use licensed titles.
Do you need a master’s degree to become a registered dietitian?
Yes. Since 1 January 2024 the Commission on Dietetic Registration has required a graduate degree to sit the registration exam for dietitians. A bachelor's alone no longer qualifies you. The degree is only one requirement, so verify the exact program’s accreditation and pathway type in ACEND’s directory.
Which nutrition certification can you get with an associate degree?
The NDTR. Nutrition and dietetics technicians registered come from the same board as dietitians, and the entry bar is an associate degree through an ACEND-accredited dietetic technician program rather than a graduate degree. Online supply for that route is thin: of the 5 online associate programs indexed here, 1 is filed under the dietetic technician code.
Is the CNS the same as the RDN?
No. The CNS comes from the Board for Certification of Nutrition Specialists and the RDN comes from the Commission on Dietetic Registration. They are different boards with different exams and different accredited routes into them. Which of the two a state licensure board recognises is decided state by state, so look up your own board before you enrol rather than after.
Can you earn a nutrition certification online?
Coursework can be completed online, but some certification routes require supervised practice at approved in-person sites. Ask whether the program arranges local placements, requires students to find preceptors or includes any campus visits.
