- Eligibility requires 2,000 pediatric nutrition practice hours as an RD within the five years before applying.
- The exam has 150 questions: 125 scored plus 25 unscored pretest items, answered in 3 hours of testing.
- Nutrition Assessment and Diagnosis is the largest domain, with 46 of the 125 scored items.
What the CSP Credential Actually Is
The Certified Specialist in Pediatric Nutrition credential, abbreviated CSP, is an advanced practice certification for registered dietitians who work with infants, children, and adolescents. It is awarded by the Commission on Dietetic Registration (CDR), the credentialing arm of the Academy of Nutrition and Dietetics, and CDR labels the issued credential Board Certified Specialist in Pediatric Nutrition. If you are still orienting yourself to the terminology, our explainers on what CSP certification is and what CSP stands for cover the basics.
One clarification matters before anything else: this credential is not the CSPCC, which is the separate pediatric critical care nutrition specialty, and it has nothing to do with the safety-professional credential that shares the same acronym. CDR's 2021 practice analysis covered both CSP and CSPCC, but it produced two distinct content outlines. Everything in this article refers only to the pediatric nutrition specialist exam.
Who Qualifies to Sit for the Exam
CSP is a specialist credential layered on top of the RD, so the gatekeeping is practical rather than academic. There are two core requirements, and both are verified through the CDR application:
- Current RD status with CDR, maintained for at least two years by the date of the specialty exam.
- 2,000 pediatric nutrition practice hours earned as an RD within the five years preceding your application for initial certification or recertification.
Approved education and professional substitutions may account for up to 800 of those hours (40 percent), but specialty hours require verification. That means you should be tracking your pediatric caseload, setting, and supervisor contact information well before you apply. Dietitians in NICU, pediatric clinics, children's hospitals, and community programs serving children typically accumulate hours differently, so the details in our CSP requirements guide are worth reading before you start counting.
Key Takeaway
Start a running log of pediatric hours now, by role and date, with a verifier for each position. Reconstructing five years of hours from memory is the most common avoidable delay in the application.
Exam Format and Testing Day Mechanics
The traditional exam is delivered year-round as a computer-based test at Pearson VUE test centers. There is no single annual testing window to plan around; you schedule when you are ready and eligible (see CSP exam dates and scheduling for the mechanics).
| Feature | CSP Exam Detail |
|---|---|
| Question count | 150 multiple-choice questions |
| Scored items | 125 scored plus 25 unscored pretest items |
| Answer format | Four options, one best answer |
| Testing time | 3 hours |
| Appointment length | 3 hours 20 minutes, including a 20-minute tutorial |
| Delivery | Pearson VUE test centers, year-round |
| Reference materials | Closed book |
What You Can and Cannot Bring
The exam is closed book. An on-screen calculator and an erasable note board are provided, and a handheld calculator supplied by the test center may be available on request. Personal calculators are prohibited. Because pediatric nutrition involves frequent calculations, practice using an on-screen calculator rather than the one you use at work.
Pacing and Breaks
Unscheduled breaks count against your testing time, so treat the three hours as continuous. With 150 items in 180 minutes, you have roughly 72 seconds per question on average. You cannot tell which 25 items are unscored pretest questions, so give every item full effort. For a sense of how the format feels in practice, see how hard the CSP exam is.
The Three Exam Domains in Detail
The scope of the exam comes from the CDR CSP Examination Content Outline (copyright 2021, effective September 2021). CDR publishes item counts per domain rather than percentage weights, so the allocations below are the official numbers of scored items. Our complete guide to all three CSP content areas goes deeper on each one.
| Domain | Scored Items |
|---|---|
| Domain 1: Characteristics of Pediatric Patient Population | 40 |
| Domain 2: Nutrition Assessment and Diagnosis | 46 |
| Domain 3: Nutrition Intervention, Monitoring, and Evaluation | 39 |
| Total | 125 |
Domain 1: Characteristics of Pediatric Patient Population (40 items)
This domain tests whether you understand the patients themselves: how children differ physiologically, developmentally, and clinically from adults, and how those differences shape nutrition needs.
- Growth and development across infancy, childhood, and adolescence, including how needs shift with age
- Conditions and disease states commonly seen in pediatric practice and their nutritional implications
- Feeding development and the factors that influence intake in different age groups
- Family, cultural, and environmental context that affects feeding and nutrition outcomes
Domain 2: Nutrition Assessment and Diagnosis (46 items)
The largest domain, and the one where the most scored items sit. Expect scenario-based questions that ask you to interpret data and reach a nutrition diagnosis.
- Interpreting anthropometric data and growth patterns against pediatric reference standards
- Reviewing biochemical, clinical, and dietary information for a pediatric patient
- Estimating energy and nutrient needs, which involves calculation and judgment about appropriate equations
- Identifying the nutrition diagnosis that best fits the assessment findings
Domain 3: Nutrition Intervention, Monitoring, and Evaluation (39 items)
This domain covers what you do once the assessment is complete and how you know whether it worked.
- Selecting and individualizing nutrition interventions for pediatric conditions
- Choosing among oral, enteral, and parenteral approaches and the rationale for each
- Setting monitoring parameters and deciding when a plan needs to change
- Evaluating outcomes and counseling or educating families and caregivers
Pass Rates and the Passing Standard
CDR publishes pass statistics for each reporting period. For January through June 2026, the reported figures were:
| Candidate Group | Pass Rate | Examinees |
|---|---|---|
| Overall | 76% | 93 |
| First-time | 72% | 42 |
| Recertification | 96% | 27 |
These numbers are retained as CDR published them. The sample sizes are small, so treat any single period as a snapshot rather than a stable benchmark. The gap between first-time and recertification candidates is notable, and it likely reflects how much daily pediatric practice experience recertifying specialists carry into the exam. Our CSP pass rate analysis discusses how to read these figures responsibly.
How the Passing Standard Works
CDR sets the passing point through an Angoff passing-point study and uses statistical equating across exam forms. In practical terms, this means there is no fixed percentage you must hit, and a candidate on a slightly harder form is not penalized relative to one on an easier form. Be skeptical of any source that claims a specific percentage-correct cutoff; see what the CSP passing score means for a fuller explanation.
Fee, Scheduling, and Retakes
The exam fee is $350, payable when you schedule your appointment. That figure is the exam fee itself and does not include study materials, travel to a test center, or the cost of any reference texts you choose to buy. For a full accounting, see the CSP certification cost breakdown.
- Apply to CDR and have your RD status and pediatric practice hours verified.
- Receive authorization to test through the CDR process.
- Schedule with Pearson VUE and pay the $350 fee at scheduling.
- Test at a Pearson VUE center on your chosen date.
If you do not pass, the ordinary retest interval is 60 days, and reauthorization is required before you can schedule again. That 60-day gap is useful planning information: if you fail, you have a defined window to target weak domains rather than rushing back in.
A Domain-Sequenced Preparation Plan
Rather than a generic weekly schedule, sequence your study around how the three domains depend on each other. Domain 2 carries the most scored items, and assessment skills feed directly into intervention decisions, so it deserves the most time and should not be left to the end. The plan below is a framework; adjust it to your own timeline and clinical background. Our CSP study guide offers additional detail.
Domain 1 Foundations
- Review growth and development across age groups, using the content outline as your checklist
- Fill gaps in conditions you rarely see in your own setting; an NICU dietitian may need more on adolescent topics, and the reverse
Domain 2 Assessment and Diagnosis
- Practice interpreting growth data and estimating energy and nutrient needs without a personal calculator
- Work case scenarios through to a nutrition diagnosis, since this is the largest block of scored items
Domain 3 Intervention and Monitoring
- Compare oral, enteral, and parenteral options and the rationale behind each
- Practice defining monitoring parameters and revising plans when outcomes fall short
Integration and Timed Practice
- Take timed mixed-domain sets at roughly 72 seconds per item
- Review misses by domain and reread the matching sections of the content outline
Use our CSP practice tests for timed mixed-domain sets, and keep a log of missed questions sorted by domain so your final-week review is targeted. A one-page distillation of key facts, like the CSP cheat sheet, can help with last-minute consolidation, but it should supplement the content outline rather than replace it.
Key Takeaway
Because the exam is closed book and calculation-heavy, practice every estimation problem using only an on-screen calculator. Familiarity with the tool saves minutes you cannot spare across 150 questions.
Renewal: The Five-Year Cycle
CSP operates on a five-year specialist cycle, and the renewal pathway is more demanding than many credentials. To recertify, you must:
- Maintain your RD status.
- Submit the eligibility application documenting 2,000 pediatric specialty hours within the preceding five years, with permitted substitutions.
- Pay the fee.
- Pass the specialist examination again.
Continuing education alone does not replace this specialist renewal exam. Your ongoing RD professional-development requirements are separate and still apply. CSP is also not included in the published CDR longitudinal-assessment pilot, which covers other specialties, so there is no alternative assessment route for CSP at this time.
Where the Credential Pays Off
CSP is most relevant to dietitians who spend their working lives with pediatric populations. Typical environments include children's hospitals, NICUs, outpatient pediatric specialty clinics, community and public health programs serving children, and pediatric-focused private practice. The credential signals depth of knowledge to employers and referral sources, and it can support advancement into clinical lead, program coordination, or education roles. See CSP jobs for the kinds of positions where it is commonly valued.
Whether the investment makes sense depends on your setting, employer expectations, and career goals. Compensation effects vary widely by region and employer, so rather than rely on a single headline number, weigh the credential against your own situation using our ROI analysis and salary guide.
Frequently Asked Questions
The Commission on Dietetic Registration (CDR) issues it, labeled Board Certified Specialist in Pediatric Nutrition. The exam is delivered by Pearson VUE at test centers year-round.
There are 150 multiple-choice questions: 125 scored and 25 unscored pretest items. You get 3 hours of testing within a 3-hour-20-minute appointment that includes a 20-minute tutorial.
No fixed percentage is published. CDR uses an Angoff passing-point study with statistical equating across forms, so the standard is set by expert judgment and adjusted for form difficulty rather than a flat cutoff.
The exam fee is $350, payable when you schedule your appointment. Study materials and travel are additional costs not included in that fee.
No. The five-year renewal requires maintaining RD status, documenting 2,000 pediatric specialty hours, paying the fee, and passing the specialist exam. Continuing education alone does not replace the renewal examination.
