What Is CSP Certification?

What CSP Means Here (and What It Does Not)

The acronym "CSP" is shared by several unrelated credentials, which is a constant source of confusion in search results. On this site, CSP means Certified Specialist in Pediatric Nutrition, a specialty credential for registered dietitians who work with infants, children, and adolescents. CDR's issuer label for it is Board Certified Specialist in Pediatric Nutrition (CSP).

Two lookalikes deserve a clear warning. The first is CSPCC, the pediatric critical care nutrition specialty, which is a separate credential with its own exam outline. The second is the unrelated safety-professional CSP, which has nothing to do with dietetics. If you have seen fees, dates, or salary claims attached to "CSP" elsewhere, check which credential they describe before trusting them. For a short orientation on the terminology itself, see our explainers on what CSP stands for and CSP meaning.

Who Issues the Credential and What It Signals

The Commission on Dietetic Registration (CDR) is the credentialing agency behind the Registered Dietitian (RD) credential, and it also administers a family of board certifications in specialty areas. CSP is one of those specialist certifications. It sits on top of RD status rather than replacing it: you cannot hold CSP without maintaining your RD credential.

What does the credential signal? Because eligibility requires documented, verified pediatric practice hours, CSP tells employers and colleagues that you have substantial hands-on experience with pediatric populations and have passed a standardized exam built around that practice. It is a specialist marker, not an entry-level qualification. For a fuller discussion of the career case, see Is the CSP Certification Worth It? Complete ROI Analysis 2026.

Eligibility: The Two Gates You Must Clear

CSP eligibility has two core requirements, and both must be met before you can sit for the exam.

1. Current RD status with CDR, maintained for at least two years by the date of the specialty exam.
2. 2,000 pediatric nutrition practice hours as an RD within the five years preceding your application, for initial certification or for recertification.

Approved education and professional substitutions may cover up to 800 of those hours (40%), and specialty hours require verification. In practice, that means you should begin documenting your pediatric hours well before you plan to apply, rather than reconstructing them from memory. The official application and eligibility pages from CDR govern the details, and our companion piece CSP Requirements 2026: Eligibility, Prerequisites & How to Qualify walks through the qualification path step by step.

How the Exam Is Built and Delivered

Question format

The traditional CSP exam consists of 150 multiple-choice questions. Of these, 125 are scored and 25 are unscored pretest items that CDR uses to evaluate future questions. You will not know which items are which, so every question deserves your full effort. Each question has four options with one best answer, which matters: "best answer" wording means several options may look defensible, and your job is to choose the one that is most appropriate for the pediatric scenario described.

Timing and environment

You get 3 hours of testing time within a 3-hour-20-minute appointment that includes a 20-minute tutorial. The exam is closed book. An on-screen calculator and an erasable note board are provided, and a test-center handheld calculator may be available on request, but personal calculators are prohibited. Unscheduled breaks count against your testing time, so plan to manage your pacing rather than assuming a pause is free.

Delivery

The exam is delivered by Pearson VUE as a computer-based test at test centers, available year-round rather than only in fixed windows. The authoritative operational details live in the CDR Specialist Certification Candidate Handbook for 2026-2027. For timing and scheduling specifics, see CSP Exam Dates 2026: Testing Windows, Deadlines & Scheduling.

How passing is determined

CDR sets the passing standard through an Angoff passing-point study and uses statistical equating across exam forms. Because of that, there is no fixed percentage you must hit, and candidates should be skeptical of any source that claims a single magic cutoff such as "you need a specific percent correct." We unpack this further in CSP Passing Score 2026: Exactly What You Need to Pass.

The Three Exam Domains

CDR's CSP Examination Content Outline organizes the exam into three domains. Published allocations are expressed as scored-item counts across the 125 scored questions, in domain order: 40, 46, and 39. Notice that the middle domain is the largest, but no domain is small enough to ignore.

These allocations are official item counts, not converted percentages, and the outline describes content areas rather than guaranteeing that every listed topic appears on every form. A deeper breakdown is available in CSP Exam Domains 2026: Complete Guide to All 3 Content Areas.

Fees, Scheduling, and Test-Day Mechanics

The CSP exam fee is $350, payable when you schedule your appointment. The sequence generally runs: confirm eligibility and submit your application through CDR, receive authorization, then schedule with Pearson VUE and pay the fee at that point. Because the exam is offered year-round, you choose your date based on your own readiness and test-center availability rather than waiting for a fixed testing window.

If you do not pass, the ordinary retest interval is 60 days, and reauthorization is required before you can schedule again. That interval has a practical consequence: treat your first attempt as the one you plan to pass, and do not schedule on a hope that you can "see what it's like" cheaply. A fuller cost picture, including how fees fit alongside other expenses, appears in CSP Certification Cost 2026: Complete Pricing Breakdown.

What the Published Results Show

CDR publishes pass/fail statistics, and the figures reported for January through June 2026 are the most current verified numbers available for this article. They are shown here exactly as published:

Two cautions are worth stating. First, these are small groups over a half-year window, so treat them as a snapshot rather than a stable long-run rate. Second, the recertification group is likely to differ systematically from first-time candidates because those examinees already hold the credential and have deep practice experience.

Renewal: Why the Five-Year Cycle Is Different

This is the feature of CSP that surprises many dietitians. The specialist certification runs on a five-year cycle, and renewing it means re-qualifying, not just logging credits. 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 exam

Continuing education alone does not replace the specialist renewal examination. Your ongoing RD professional-development requirements are separate and still apply. Also note that CSP is not included in the published longitudinal-assessment pilot that CDR has run for certain other specialist credentials, so you should not plan around an alternative to the exam. The recertification group's strong showing in the pass-rate table above reflects this reality: these are experienced practitioners sitting the exam again.

Where CSP Fits in a Career

Pediatric dietitians work wherever children receive nutrition care. Typical settings include children's hospitals and pediatric units, outpatient specialty clinics (such as those serving children with complex medical conditions), neonatal and infant feeding programs, community and public-health programs serving children and families, and long-term or home-based care for medically complex pediatric patients. Employers in these settings tend to value documented specialty experience, and CSP is one concrete way to demonstrate it.

Whether the credential changes your title, responsibilities, or pay depends heavily on the employer and region, so we avoid quoting numbers here. If compensation is your main question, read CSP Salary Guide 2026: Complete Earnings Analysis, and for the job landscape see our overview of CSP jobs.

Sequencing Your Preparation Around the Domains

Rather than generic study advice, let the exam's own structure set your order. CDR publishes a suggested-reference list (dated September 2024) that 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 CDR does not endorse any particular preparation product. Anchor your plan to the official content outline first.

When you are ready to test yourself against realistic multiple-choice items, work through the CSP practice tests and use the results to decide where to spend your remaining study time.
