1.2 Eligibility & Application Process

The Two Eligibility Pillars

CDR sets two gatekeeping requirements before you may sit for the CSP exam, and both must be satisfied at the time you apply.

Pillar 1: Tenure as a registered dietitian. You must hold a current CDR RD or RDN credential and have maintained it for at least 2 years from the date of your original registration examination. This is why the CSP is a mid-career credential by design: it cannot be earned immediately after passing the RD exam, no matter how strong a candidate's pediatric rotation experience was.

Pillar 2: Documented pediatric practice. You must document 2,000 hours of pediatric nutrition practice as an RD within the past 5 years. Only practice performed after becoming an RD counts; dietetic internship hours and pre-credential work experience do not.

The 5-Year Documentation Nuance

The phrase "within the past 5 years" is widely misunderstood. The 5-year mark is a look-back ceiling, not a duration requirement. You are not required to show five full years of pediatric practice. You only need to document as far back as necessary to reach 2,000 hours, and you may not reach further back than five years.

The arithmetic makes this concrete. A full-time position is roughly 2,000 working hours per year, so a dietitian in a fully pediatric role - say, a NICU dietitian who does nothing but pediatric work - could plausibly accumulate the required hours in about a year of full-time practice, and would document only that period. A dietitian whose role is 50% pediatric would need roughly twice as long, and would document proportionally further back within the 5-year window. The practical advice: tally your actual pediatric hours first, then document only the period needed to demonstrate 2,000.

The 40% Substitution Rule

Up to 40% of the 2,000 hours - that is, 800 hours - may be substituted by certain education and professional experiences rather than direct practice. This flexibility recognizes that activities such as relevant graduate education, teaching, research, or other professional contributions can build pediatric expertise. The floor is still substantial: at least 1,200 hours must come from documented pediatric nutrition practice as an RD. When applying, follow the current CDR guidance on exactly which experiences qualify and how they are credited, and keep supporting documentation organized, because the burden of proof rests with the applicant.

What Counts as Pediatric Nutrition Practice

Qualifying hours are hours spent practicing pediatric nutrition as an RD - direct patient care such as assessment, intervention, and monitoring for patients from birth through age 21, along with closely related professional work in the specialty. If your role mixes pediatric and adult populations, only the pediatric portion counts, so estimate honestly and keep records that could withstand scrutiny: job descriptions, employer verification, and your own contemporaneous logs of hours and duties. Candidates sometimes discover at application time that a nominally pediatric job was only 60% pediatric in practice; running that calculation a year before you intend to apply, rather than the week of, gives you time to accumulate the shortfall instead of delaying your eligibility.

How to Apply

The application runs through CDR's online portal:

1. Log in to MyCDR and select "Apply for Specialist Certification."
2. Complete the specialist application, documenting your pediatric practice hours (and any substitute experiences) as instructed.
3. CDR reviews the application and confirms your eligibility. Note that pediatric practice hours must be verified before the application can be submitted, and CDR advises that processing with CDR and the testing vendor can take up to two full weeks.
4. Within about 48 hours of approval you receive an Authorization to Test (ATT) email from Pearson VUE, CDR's testing agency, listing your authorization dates and explaining how to create login credentials.
5. Schedule the appointment and pay the $350 fee on the CDR/Pearson web portal (or by phone). The handbook is explicit on the sequence: the examination fee is paid when scheduling an appointment, not when the application is submitted. The exam is offered year-round at over 250 Pearson professional test centers in the United States and select international locations, so there is no fixed national test date to plan around.

The 1-Year Eligibility Window

Approval is not open-ended. Your eligibility period lasts 1 year, and you must both schedule and actually take the exam within that window. If the year lapses without an appointment being scheduled, the authorization simply expires and you must complete the eligibility application again to obtain a new one-year window. (Because the fee is paid at scheduling rather than at application, an unused authorization costs you time and paperwork rather than the $350 itself - but a booked appointment you fail to attend is not refunded.) Two habits protect you here: schedule promptly after approval rather than waiting for a perfect study season, and treat the eligibility end date as a hard deadline when planning your calendar. (Within an unexpired authorization year, retakes - covered in Section 1.3 - do not require a new eligibility application, though reauthorization must still be requested.)

Fees, Scheduling, and Accommodations

Testing accommodations are available for candidates with documented physical, mental, sensory, or learning disabilities. CDR does not publish a fixed notice period; the handbook instead instructs candidates to apply as early as possible, because accommodations must be approved in advance of scheduling and approved candidates must book by phone through the Accommodations Program Coordinator rather than online. Two details catch people out: documentation must be resubmitted every time accommodations are requested for an examination, and you must already be eligible for the specialist exam before you can apply for them. Documenting the presence of a disability is not sufficient - the impact on your ability to take this examination must be quantifiably documented.

A final strategic note: because the fee is charged per attempt and the eligibility clock runs for a fixed year, the cheapest and least stressful path is a single, well-prepared attempt scheduled early enough in the window that a 60-day retake wait still fits if things go wrong. The policies in the next section show exactly how much slack that leaves.
