CSG: Suggested Study Strategy
Frequently Asked Questions
Who is eligible for CSG certification?
CDR requires current Registered Dietitian status held at least two years by the specialty examination date and 2,000 documented gerontological nutrition practice hours within five years before application. Permitted education/professional substitutions can cover up to 40% (800 hours). CDR must approve the eligibility application.
What is the CSG examination format?
The current CDR handbook specifies 150 multiple-choice items: 125 scored and 25 indistinguishable pretest items. Candidates have three hours for the examination. The appointment is three hours twenty minutes including a twenty-minute tutorial.
What does the CSG examination cover?
The current CDR outline allocates 55 scored items to Nutrition Assessment, 47 to Nutrition Interventions, and 23 to Foodservice and Food Safety. These represent 44%, 37.6%, and 18.4% of the 125 scored items; the last two percentages are often rounded to 38% and 18%.
How much does the CSG examination cost and where is it offered?
CDR’s current CSG fee page and specialist handbook publish a $350 examination fee, paid when scheduling. Examinations are offered year-round at Pearson test centers in the United States and selected international locations. Review the current CDR handbook and scheduling instructions before booking.
What is the CSG passing score?
CDR establishes a criterion-referenced passing standard using an Angoff study and equates forms for difficulty. The current handbook does not publish a fixed percentage-correct requirement. A practice-question percentage is not an official passing-score conversion.
Can I retake the CSG examination?
After an unsuccessful attempt, request reauthorization from CDR; it is not automatic. Candidates normally may retest after 60 days. If the one-year eligibility window has expired or expires during that waiting period, submit a new eligibility application. The handbook describes a limited employment-related one-time waiting-period waiver.
How should I plan CSG study and recertification?
Use CDR’s current outline and reference list to identify gaps and practice applied cases. A 60–100-hour plan is an OpenExamPrep planning estimate, not an official requirement. CSG certification lasts five years; recertification requires current RD status, the eligibility/practice-hour requirements, payment, and passing the specialty examination.
