CSG Pass Rate 2026: What the Data Shows

What CDR's January-June 2026 Numbers Say

Candidates searching for a CSG pass rate usually want one thing: a signal about how risky the exam is. For the Certified Specialist in Gerontological Nutrition credential, awarded by the Commission on Dietetic Registration (CDR), the most useful source is CDR's own CSG certification pass/fail statistics page. For the January-June 2026 reporting window, it shows:

Two things stand out immediately. First, the pools are small: 71 total examinees in a six-month window. Second, a first-time pass rate of 87% means roughly six of every 47 first-time candidates in that window did not pass. That is not a trivial miss rate, even though the headline number looks comfortable. If you want to calibrate how much preparation the exam deserves, read these figures alongside our guide on how hard the CSG exam is rather than treating 90% as a reason to relax.

The Recertification Row: A Percentage and Count That Don't Match

CDR's published recertification row pairs a 96% rate with a count of 21 of 22. Those do not agree: 21 of 22 works out to a figure closer to 95%, not 96%. We are reporting the row exactly as CDR published it and are not "correcting" it, because we cannot know whether the percentage or the count reflects the intended figure (a late data update, a different denominator, or a transcription issue are all possible explanations, and none is confirmed).

The practical takeaway is modest. Whichever number is right, recertification examinees, who are by definition already certified specialists, passed at a very high rate in a tiny pool of 22. Do not build a study strategy on the difference between 95% and 96%. If you need the figure for a report, cite the CDR page directly and note the inconsistency.

Why There Is No Fixed Percentage of Candidates Who Pass

A common misconception is that specialist exams are curved so that a set proportion of candidates passes or fails. That is not how the CSG exam works. Passing is established through Angoff standard setting, in which subject-matter experts judge how a minimally competent specialist would perform on each item, combined with statistical equating that adjusts for differences in difficulty between exam forms.

This has two consequences for how you read a pass rate:

• Your result does not depend on how other candidates perform. A strong or weak cohort in your testing window does not change the standard you are held to.
• Pass rates move with candidate readiness, not with a quota. If a given half-year's pool is better prepared, the rate rises; if less prepared, it falls.

CDR does not supply a raw passing percentage (for example, "answer X% correctly") in the materials we reviewed, and we will not invent one. For a fuller discussion of what is and isn't published, see our breakdown of the CSG passing score.

Why the Pool Is Self-Selected

A 90% overall rate reflects who is allowed to sit the exam as much as how hard the questions are. CSG eligibility is demanding:

• Current CDR Registered Dietitian (RD) status, held for at least two years by the examination date.
• 2,000 verified hours of gerontological-nutrition specialty practice as an RD during the five years before applying.
• Approved education or professional substitutions may cover up to 800 of those hours.

That means every examinee already holds the RD credential and has years of practice, with a substantial block of it in older-adult nutrition. The exam is not screening general dietetics knowledge from scratch; it is testing whether experienced RDs can apply specialist judgment across assessment, intervention and foodservice in geriatric settings. A high pass rate among a pre-screened, experienced pool is exactly what you would expect, and it says little about how a less experienced candidate would fare. Review the full prerequisites in our CSG requirements guide before assuming the statistics describe your situation.

Exam Format Details That Shape Your Odds

The format itself affects how pass-rate data translates into your planning:

• 150 multiple-choice questions, each with one best answer from four options.
• 125 scored items plus 25 unscored pretest questions. You cannot tell which are which, so treat every question as if it counts.
• Three hours of actual testing time, plus a separate 20-minute tutorial, for an appointment of three hours 20 minutes.
• Closed-book, with an on-screen calculator provided; personal calculators are prohibited.
• No skipping ahead: the current question must be answered before you advance, and ordinary unscheduled breaks do not stop the timer.
• Delivered at Pearson VUE test centers through year-round computer-based testing. The content outline still carries PSI branding, but the 2026-2027 CDR Specialist Certification Candidate Handbook identifies Pearson as the current provider, so rely on the handbook for test-day policies.

Three hours for 150 items works out to just over a minute per question including the pretest items. Because you must answer before moving on, you cannot bank hard questions for later, so pacing discipline matters. Questions that involve calculations (energy and protein needs, tube-feeding or hydration math, for instance) are where the on-screen calculator and a rehearsed approach save time. For scheduling windows and logistics, see CSG exam dates and scheduling.

Domain by Domain: Where Passing Is Won

CDR's content outline allocates scored items across three domains. These are item counts, not published percentage weights, and we present them as counts only:

Together these account for the 125 scored questions. The distribution tells you where a pass is most likely to be decided. For a deeper walk through each area, see our complete guide to the three CSG content areas.

Because a pass is determined by overall performance against the standard, a strong showing in the two big domains can absorb some weakness in the smaller one, but not an unlimited amount. Candidates who treat foodservice as an afterthought give up a block of items that is comparatively cheap to learn.

A short, domain-weighted study sequence

Generic study methods matter less than allocating time where the items are. One sensible sequence for an experienced RD, built around the item counts above:

For a fuller plan, including source material, see our CSG study guide. CDR also publishes a reference list for the exam (the July 2025 update). It is a reading list, not an exam blueprint, so use it alongside the content outline rather than instead of it. When you want realistic question practice, the CSG practice tests are built around the same three-domain structure.

Retest Rules, Fee Exposure and Renewal Reality

Pass-rate data matters partly because failing is expensive and slow. The exam fee is USD $350, paid at scheduling. If you do not pass, retesting normally requires reauthorization and a 60-day wait, so a miss costs you both another fee exposure and at least two months. Full pricing context is in our CSG certification cost breakdown.

Also keep in mind that the credential is valid for five years and cannot be maintained by continuing education alone. Renewal requires current RD status, a new eligibility application including the applicable specialty-practice hours, exam payment and another passing specialist examination. That means the high "recertification" pass numbers above reflect certified specialists sitting the exam again, and it means you will face this exam, and these odds, more than once if you keep the credential long term.

Using the Data to Set Your Prep Plan

Here is a sober way to use the January-June 2026 figures:

1. Respect the first-time rate. 87% (41 of 47) means a meaningful minority of first-time candidates still do not pass, despite being experienced RDs. Do not assume experience alone carries you.
2. Don't over-read one half-year. Small cohorts make the percentages volatile. Check CDR's statistics page for the current window rather than relying on any single snapshot, including ours.
3. Allocate by item counts. Put the most hours into Nutrition Assessment (55 items) and Nutrition Interventions (47), but reserve real time for Foodservice and Food Safety (23).
4. Practice in exam conditions. Three hours, no skipping, no stopping the clock, calculator on screen.
5. Match your prep to your gaps, not your habits. If most of your 2,000 hours were in one care setting, deliberately review the others.

If you are still deciding whether the effort is justified, our analysis of whether the CSG is worth it weighs the cost and exam burden against career value, and the CSG salary guide covers earnings context without relying on invented figures. For a quick last-pass review before test day, the CSG cheat sheet condenses the must-know facts.
