CSP Pass Rate 2026: What the Data Shows

What CDR Actually Published for 2026

The Certified Specialist in Pediatric Nutrition credential is issued by the Commission on Dietetic Registration (CDR), and CDR publishes pass/fail statistics for the exam. For the January-June 2026 reporting window, the published figures are:

These numbers come directly from CDR's CSP pass/fail statistics page and are reported here as published. They are not reconstructed from rounded percentages, and this article does not extrapolate them into full-year projections. If you want the single-page summary of how this fits with the rest of the exam picture, see our overview in CSP Pass Rate 2026: What the Data Shows.

Reading the Numbers Without Overreaching

The sample is small

Ninety-three examinees in a six-month window is a modest cohort. Specialist exams in dietetics draw far fewer candidates than the RD credentialing exam, and that has two practical consequences. First, a handful of additional passes or failures shifts the percentage noticeably. Second, comparing one reporting window against the next can mislead if you treat small movements as trends. With 42 first-time examinees, a swing of just a few candidates changes the first-time rate by several points.

What the figures do and do not tell you

• They do tell you that a clear majority of candidates in this window passed, and that the exam is passable for prepared RDs with substantial pediatric experience.
• They do not tell you the score distribution, the number of attempts per candidate, or how preparation habits correlate with outcomes. CDR does not publish those details.
• They do not set a bar for you. Because passing is determined through standard setting and equating rather than a fixed percentage, your own raw percentage on practice sets is only a rough guide.

Why First-Time Candidates Trail Recertifiers

The gap between 72% first-time and 96% recertification is the most instructive line in the data. CDR does not publish causal analysis, so what follows is reasoned interpretation rather than reported fact.

• Recertifiers have already passed once. They have demonstrated competence on this exam's content and know its item style.
• Recertifiers are working in the specialty. The renewal pathway requires documenting 2,000 pediatric nutrition practice hours within the preceding five years, so they are, by definition, currently practicing in pediatrics.
• First-time candidates are a more varied group. Some arrive from deep, long-standing pediatric roles; others have just crossed the 2,000-hour threshold, possibly with approved substitutions covering part of it.

Who Is Allowed to Sit: The Eligibility Filter

Pass rates for any specialist exam reflect a pre-screened population. To be eligible for the CSP exam, candidates must:

• Hold current Registered Dietitian status with CDR, maintained for at least two years by the specialty exam date.
• Document 2,000 pediatric nutrition practice hours as an RD within the five years preceding the application for initial certification or recertification.
• Have specialty hours verified. Approved education and professional substitutions may cover up to 800 hours (40%) of the requirement.

This filter means the 76% overall figure describes experienced RDs, not the general dietetics population. An RD with no pediatric background cannot sit for the exam at all. That screening likely lifts pass rates relative to an open-enrollment exam, which is worth remembering when you compare this credential to others. Full eligibility details, including how substitutions are verified, are covered in CSP Requirements 2026: Eligibility, Prerequisites & How to Qualify.

Exam Format and How Passing Is Decided

The structure

The traditional exam contains 150 multiple-choice questions: 125 scored items and 25 unscored pretest items. Each question has four options with one best answer. Candidates get 3 hours of testing time within a 3-hour-20-minute appointment that includes a 20-minute tutorial. Delivery is computer-based at Pearson VUE test centers, available year-round.

You cannot tell which items are unscored, so every question deserves full effort. The pretest items exist so CDR can evaluate new questions before they count toward anyone's result.

No fixed percentage pass mark

CDR's passing standard comes from an Angoff passing-point study, with statistical equating across exam forms. In plain terms, subject-matter experts judge how a minimally competent specialist would perform on each item, and equating adjusts for the fact that different forms may vary slightly in difficulty. The practical upshot is that "you need X%" is not a claim this article, or any honest source, can make. For a deeper treatment, see CSP Passing Score 2026: Exactly What You Need to Pass.

Where the Scored Items Sit

The CSP Examination Content Outline (CDR, copyright 2021, currently linked file effective September 2021) organizes the exam into three domains. The published allocations are official scored-item counts, in domain order, totaling 125:

The counts are retained as published; CDR does not publish percentage weights, so none are asserted here. The spread is notably even. No single domain dominates, and none can be neglected without cost.

Because Domain 2 holds the most items, it merits the most study hours, but the 40/46/39 spread means a weak domain anywhere can pull you down. A detailed breakdown with topic-level guidance lives in CSP Exam Domains 2026: Complete Guide to All 3 Content Areas.

Testing-Day Mechanics That Affect Outcomes

Pass rates are shaped partly by content mastery and partly by avoidable test-day friction. These CSP-specific mechanics are worth knowing in advance:

• Closed book. No reference materials are permitted during the exam.
• Calculator rules. An on-screen calculator and an erasable note board are provided. A test-center handheld calculator may be available on request, but personal calculators are prohibited. Practice your pediatric calculations (energy needs, fluid, formula concentrations, percentile-based reasoning) using an on-screen calculator so the interface is not a surprise.
• Breaks cost time. Unscheduled breaks count against your testing time, so the 3 hours is effectively continuous.
• Time budget. With 150 items in 180 minutes, you have roughly 72 seconds per item on average. Scenario questions will take longer, so quick recall items need to be fast.
• Fee and scheduling. The $350 exam fee is payable when you schedule. Pricing context for the full credential lifecycle is in CSP Certification Cost 2026: Complete Pricing Breakdown, and scheduling logistics are in CSP Exam Dates 2026: Testing Windows, Deadlines & Scheduling.

A Domain-Weighted Preparation Sequence

CDR does not endorse a specific preparation product, but it does publish a suggested-reference list (dated September 2024). That list includes the Texas Children's Hospital Pediatric Nutrition Reference Guide, 13th edition (2022), and the Pediatric Nutrition Care Manual. These are suggested preparation resources, not a separate exam blueprint, and they are not guaranteed to cover every tested item, so use them alongside the content outline rather than instead of it.

Here is one way to sequence an eight-week plan around the official item counts. Adjust it to your own strengths and the pediatric populations you already work with.

Retakes, Renewal, and the Long Game

If you do not pass

The ordinary retest interval is 60 days, and reauthorization is required before you can schedule again. That is long enough to do a genuine diagnostic review of what went wrong. Use the window to identify whether the problem was content gaps, time management, or item interpretation, rather than simply re-reading the same material. Our practice question bank can help isolate weak domains during that interval.

Why the recertification rate is so high

CSP certification runs on a five-year cycle. To renew, a specialist must maintain RD status, submit the eligibility application documenting 2,000 pediatric specialty hours within the preceding five years (with permitted substitutions), pay the fee, and pass the specialist exam again. Continuing education alone does not replace the renewal examination, and ongoing RD professional-development requirements are separate obligations. CSP is also not included in CDR's published CSO/CSSD longitudinal-assessment pilot, so the exam remains the renewal route. The 96% recertification pass rate fits this picture: renewing candidates are experienced, actively practicing, and have already cleared the exam once.
