- The exam has 150 multiple-choice questions, but only 125 are scored; 25 are unscored pretest items.
- Nutrition Assessment and Diagnosis is the largest domain, with 46 scored items.
- The fee is $350, paid when you schedule through Pearson VUE.
- Eligibility requires 2,000 pediatric practice hours as an RD within the preceding five years.
Which CSP This Sheet Covers
Before the facts, a quick identity check, because the acronym is crowded. This cheat sheet covers the Certified Specialist in Pediatric Nutrition, issued by the Commission on Dietetic Registration (CDR) and labeled Board Certified Specialist in Pediatric Nutrition (CSP). It is not the pediatric critical care nutrition specialty (CSPCC), and it has nothing to do with the safety-professional credential that shares the letters. If you are comparing sources, make sure every fee, date, and content outline you rely on comes from CDR's pediatric nutrition pages. For background on the name itself, see What Does CSP Stand For? and What Is CSP Certification?.
The Exam at a Glance
This is the part of the sheet to memorize first. Every figure below comes from CDR's Specialist Certification Candidate Handbook 2026-2027 and related CDR pages.
| Item | Fact |
|---|---|
| Credentialing body | Commission on Dietetic Registration (CDR) |
| Testing provider | Pearson VUE, computer-based at test centers, year-round |
| Exam fee | $350, payable when scheduling |
| Total questions | 150 multiple choice (125 scored + 25 unscored pretest) |
| Answer format | Four options, one best answer |
| Testing time | 3 hours, inside a 3-hour-20-minute appointment that includes a 20-minute tutorial |
| Passing standard | Angoff passing-point study with statistical equating across forms; no fixed percentage pass mark is published |
| Retest interval | Ordinarily 60 days, with reauthorization required |
Two details trip people up. First, you cannot tell which 25 questions are unscored, so treat all 150 as if they count. Second, because forms are statistically equated, there is no "get 70% and you pass" shortcut. For a deeper treatment, read CSP Passing Score 2026: Exactly What You Need to Pass.
Eligibility Snapshot
The CSP is a specialty credential layered on top of the RD, so the prerequisites are about both status and experience:
- Current RD status with CDR, maintained for at least two years by the specialty exam date.
- 2,000 pediatric nutrition practice hours as an RD within the five years preceding your application, for initial certification or recertification.
- Permitted substitutions: approved education and professional activities may cover up to 800 hours (40%) of the requirement.
- Verification: specialty hours require verification as part of the application.
Start the paperwork early, because the application is what unlocks scheduling and the $350 fee payment. The full walkthrough is in CSP Requirements 2026: Eligibility, Prerequisites & How to Qualify, and the cost picture is broken out in CSP Certification Cost 2026: Complete Pricing Breakdown.
Domain Map and Item Counts
CDR's CSP Examination Content Outline (copyright 2021, effective September 2021) defines three domains. CDR publishes scored-item counts rather than percentage weights, so the table below keeps the official counts as published.
| Domain | Official Heading | Scored Items |
|---|---|---|
| 1 | Characteristics of Pediatric Patient Population | 40 |
| 2 | Nutrition Assessment and Diagnosis | 46 |
| 3 | Nutrition Intervention, Monitoring, and Evaluation | 39 |
The counts total 125, matching the scored-question figure. Domain 2 is the largest, but notice how close the three are: no domain is small enough to ignore. A candidate who is strong on assessment but weak on intervention can still lose a lot of points. The content outline PDF is the authoritative scope document, and our CSP Exam Domains 2026: Complete Guide to All 3 Content Areas expands each area in depth.
Clinical Content to Have Cold
The outline is the boundary of what can be tested; the items below are the kinds of working knowledge a pediatric RD should be able to apply under time pressure. Treat them as study prompts, and confirm specifics against the official outline and your references.
Domain 1: Characteristics of Pediatric Patient Population
Know how children differ from adults physiologically and developmentally, and how those differences change nutrition needs across age groups.
- Growth and development patterns from infancy through adolescence
- Feeding development and milestones, and what delayed progression signals
- Conditions that change requirements, from prematurity to chronic disease
- Population-level considerations that affect how care is delivered
Domain 2: Nutrition Assessment and Diagnosis
The heaviest domain at 46 scored items. Expect questions that hand you data and ask what it means.
- Anthropometrics and growth-chart interpretation, including when to question a measurement
- Biochemical, clinical, and dietary data and how they combine into a diagnosis
- Estimating energy and nutrient needs for different ages and conditions
- Writing and selecting nutrition diagnoses that fit the evidence presented
Domain 3: Nutrition Intervention, Monitoring, and Evaluation
Questions here ask what you would do and how you would know it worked.
- Choosing among oral, enteral, and parenteral approaches and the rationale for each
- Formula and feeding-regimen decisions, advancement, and tolerance
- Defining outcomes, follow-up intervals, and when to change the plan
- Education and counseling approaches suited to caregivers and age
CDR's suggested-reference list (dated September 2024) names the Texas Children's Hospital Pediatric Nutrition Reference Guide, 13th edition (2022), and the Pediatric Nutrition Care Manual among its preparation resources. These are suggested references, not a separate exam blueprint, and CDR does not guarantee any single book covers every tested item. Pair them with the outline rather than substituting them for it.
Test-Day Rules and Logistics
- Closed book. No notes or reference materials in the testing room.
- Calculator: an on-screen calculator is built in. A test-center handheld calculator may be available on request, but personal calculators are prohibited.
- Scratch work: an erasable note board is provided.
- Tutorial time: the 20-minute tutorial sits inside your 3-hour-20-minute appointment but does not eat into the 3 hours of testing.
- Breaks: unscheduled breaks count against testing time.
- Scheduling: delivery is year-round at Pearson VUE test centers, so you choose your own date after authorization. See CSP Exam Dates 2026: Testing Windows, Deadlines & Scheduling for the mechanics.
Pass-Rate Data, Read Carefully
CDR publishes pass statistics by candidate group. The most recent figures available for this sheet cover January through June 2026, retained here exactly as CDR reports them:
| Candidate Group | Pass Rate | Examinees |
|---|---|---|
| Overall | 76% | 93 |
| First-time | 72% | 42 |
| Recertification | 96% | 27 |
Two cautions. The samples are small, so a single percentage point shifts with very few candidates, and a six-month window is not a trend. And the gap between first-time and recertification candidates is worth noticing: those renewing have already demonstrated sustained pediatric practice. First-timers should take that as a nudge to treat the exam as a real clinical-reasoning test. We unpack the numbers in CSP Pass Rate 2026: What the Data Shows, and the difficulty question gets its own treatment in How Hard Is the CSP Exam? Complete Difficulty Guide 2026.
Five-Year Renewal Cycle
The CSP runs on a five-year specialist cycle, and the renewal rules are the single biggest surprise for new credential holders:
- Maintain your RD status.
- Submit the eligibility application documenting 2,000 pediatric specialty hours within the preceding five years, using permitted substitutions where applicable.
- Pay the fee.
- Pass the specialist exam again.
Continuing education alone does not replace the renewal exam. Ongoing RD professional-development requirements are separate obligations that you still have to meet. Also note that the CSP is not included in CDR's published longitudinal-assessment pilot, which covers other specialties, so do not plan around an alternative to retesting. Keep a running log of qualifying hours across the whole cycle rather than reconstructing them in year five.
Key Takeaway
Think of the CSP as a recurring commitment, not a one-time test. Track pediatric practice hours from the day you certify, because the same 2,000-hour standard returns at every renewal.
Sequencing Your Review
Generic study advice is plentiful; the useful question is how to order this content. Because the domains build on each other, a sequence that mirrors the outline works well:
Domain 1 foundations
- Review growth, development, and feeding milestones first, since every later assessment question assumes them
- Build a one-page summary of how needs shift across age groups
Domain 2 depth
- Give the most time here: it carries 46 scored items
- Drill growth-chart interpretation and needs estimation with worked examples
Domain 3 application
- Practice intervention selection and monitoring plans from case-style prompts
- Finish with mixed-domain practice under a 72-second-per-question pace
A fuller plan is laid out in CSP Study Guide 2026: How to Pass on Your First Attempt. When you are ready to test your recall under realistic conditions, the CSP practice test is built around this exact format.
Where the Credential Is Used
The CSP signals advanced pediatric nutrition practice, and it tends to be most relevant in settings where children's nutrition is the core of the role: children's hospitals and pediatric units, outpatient pediatric clinics, and programs serving children with chronic or complex conditions. It sits on top of an RD, so employers are already screening for clinical competence; the specialty credential helps document depth in the pediatric population. Compensation and hiring outcomes vary by employer and region, and we avoid quoting unsupported figures here.

FAQ
The exam has 150 multiple-choice questions. Of those, 125 are scored and 25 are unscored pretest items. You cannot tell which are which, so answer every question with full effort.
The fee is $350, payable when you schedule your exam through Pearson VUE after your application is approved. See the cost breakdown article for the full financial picture.
Domain 2, Nutrition Assessment and Diagnosis, has the most scored items at 46. Domain 1 has 40 and Domain 3 has 39, for a total of 125 scored items.
No fixed percentage is published. CDR uses an Angoff passing-point study with statistical equating across exam forms, so the standard is set by expert judgment rather than a flat cutoff.
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 exam, and ongoing RD professional-development requirements are separate.
Keep this sheet beside the official content outline and the Candidate Handbook, verify any detail that affects your application against CDR's current pages, and use realistic practice questions to confirm the facts have stuck before you schedule.
