- GS-C is the Gerontology Nursing Certification Commission's APRN specialty credential, supplemental to your primary APRN certification.
- The exam has 175 multiple-choice questions, a four-hour limit, and a 73% passing score.
- Four domains tie for the largest weight at 20% each: Assessment, Screening/Diagnosis/Care Planning, Pharmacotherapy, and Transitions of Care.
- Eligibility requires 2,500 older-adult APRN practice hours and 50 gerontology-specific CE hours, both within defined lookback windows.
What GS-C Actually Means
GS-C stands for Gerontological Specialist - Certified. It's an advanced practice nursing credential specific to the care of older adults, awarded by the Gerontology Nursing Certification Commission (GNCC). If you've seen the letters "GS-C" attached to a different profession or a different testing body elsewhere online, that is not this credential - this page and this site cover only the GNCC's Gerontological Specialist - Certified designation for APRNs.
GS-C is not a standalone license. It sits on top of your existing national APRN certification and unrestricted RN license, signaling that you've demonstrated focused competency in the assessment, treatment, and care coordination of complex older adult patients. For a broader orientation to the credential before diving into exam mechanics, see GS-C Certification and What Is GS-C?
Who Awards the Credential and Why It Matters
GNCC reviews and approves every application. The Gerontological Advanced Practice Nurses Association (GAPNA) is the professional association behind the specialty and supplies preparation resources, but GNCC - not GAPNA - is the certifying body that issues the credential itself. Computer-based exams are delivered at PSI testing centers nationwide, using standard proctored testing-center protocols.
This distinction matters for candidates because your membership status with GAPNA affects your exam fee, but your application and eligibility review go through GNCC. If you're researching what the letters mean before committing to the process, related short explainers on this site include GS-C Meaning, What Does GS-C Stand For?, and What Does GS-C Mean?
Eligibility Requirements
Before you can sit for the exam, GNCC requires that you meet all of the following:
- An unrestricted RN license in a US state or territory
- Compliance with your state's APRN requirements
- Current national APRN certification
- 2,500 hours of professional APRN practice with older adults within the preceding five years
- 50 accredited gerontology-specific continuing education contact hours within the preceding three years
One detail candidates frequently miss: the initial 50 CE hours must be earned as a learner. Teaching a course, precepting students, or publishing on gerontology topics does not count toward this initial requirement, even though those same activities can count toward renewal later. Plan your CE accumulation accordingly rather than assuming presentation or authorship credits will satisfy the initial application.
For the full breakdown of documentation, timelines, and how the hour requirements interact, read GS-C Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Key Takeaway
Track your gerontology CE hours as a learner from day one of specialty practice - teaching and publishing credits won't rescue an initial application that's short on learner-based contact hours.
Exam Format and Registration Mechanics
Once GNCC approves your application, you receive a 90-day examination permit. You must bring that permit plus matching government-issued photo identification to your PSI testing center appointment. Personal electronic devices are prohibited in the testing room, so plan your arrival and storage of belongings accordingly.
The exam itself contains 175 multiple-choice questions administered over four hours, with a required passing score of 73%. Fees depend on GAPNA membership status:
| Fee Type | GAPNA Member | Nonmember |
|---|---|---|
| Initial Examination | $295 | $395 |
| Renewal by CE | $275 | $375 |

The Six-Domain Blueprint
GS-C's content outline changed in November 2024, when a new exam form replaced the previous seven-domain structure with the current six-domain blueprint. If you're studying from older materials, confirm they reflect this updated structure before relying on them.
Domain 1: Comprehensive Assessment of the Complex Older Adult (20%)
Covers functional, cognitive, and physical assessment approaches tailored to older adults with multiple comorbidities.
- Geriatric-specific assessment tools and their appropriate application
Domain 2: Screening, Diagnostic Testing, Treatment, and Care Planning (20%)
Tests your ability to move from findings to an appropriate, individualized plan of care.
- Differentiating normal aging from pathology in screening results
Domain 3: Pharmacotherapy (20%)
Focuses on prescribing decisions weighing risk and benefit specifically in older adults.
- Polypharmacy, drug-drug interactions, and age-related pharmacokinetic changes
Domain 4: Educational Strategies for Health Outcomes (14%)
Covers system-based patient and caregiver education design.
- Tailoring education delivery to cognitive and literacy constraints
Domain 5: Transitions of Care (20%)
Addresses anticipating and managing moves between care settings, including transitions to palliative or hospice care.
- Coordinating handoffs across providers and sites of care
Domain 6: Systems-Based Resource Deployment (6%)
The smallest-weighted domain, focused on population-level resource allocation for older adults.
- Identifying and deploying community and systems resources
Notice that four domains - Assessment, Screening/Diagnosis/Care Planning, Pharmacotherapy, and Transitions of Care - are tied at 20% each, meaning together they represent the large majority of the exam. Domain 6, at only 6%, deserves proportionally less study time. For a deeper walk-through of each domain with sample topic lists, see GS-C Exam Domains 2026: Complete Guide to All 6 Content Areas.
Passing Score and Pass Rate Context
You need a 73% score to pass. GNCC's calendar-year 2024 report shows 43 of 56 first-time candidates passing, a first-time pass rate of 76.8%. That figure describes a specific historical cohort - it is not a projection for 2026 or any future exam administration, and it shouldn't be treated as a guarantee for any individual candidate's odds.
For more on how the passing score is calculated and what it means for question-level performance, read GS-C Passing Score 2026: Exactly What You Need to Pass. For fuller pass-rate context and how to interpret cohort data responsibly, see GS-C Pass Rate 2026: What the Data Shows.

Certification Period and Renewal
GS-C certification is valid for five years. To renew by continuing education, you must maintain your RN licensure and national APRN certification, log 1,000 older-adult APRN practice hours during the certification period, and complete 80 qualifying CE contact hours - at least 50 of which must be gerontology-specific, plus 30 additional eligible hours. Unlike the initial application, renewal-period CE can include teaching, precepting, and publication activities.
Examination is also an accepted renewal route if you'd rather demonstrate current competency by retesting instead of accumulating CE hours. Renewal fees run $275 for GAPNA members and $375 for nonmembers.
Who Hires GS-C Holders
GS-C is designed for APRNs already practicing with older adult populations - nurse practitioners and clinical nurse specialists working in geriatric primary care, transitional care, skilled nursing and long-term care facilities, palliative and hospice settings, and hospital-based geriatric consult services. Because the credential validates specialty competency on top of an existing APRN license, employers in these settings tend to view it as evidence of focused expertise rather than a replacement for core credentials.

A GS-C-Specific Way to Plan Prep
Rather than a generic multi-week calendar, anchor your prep schedule to the domain weights. Because Assessment, Screening/Diagnosis/Care Planning, Pharmacotherapy, and Transitions of Care each carry 20% of the exam, they deserve roughly equal, heavier blocks of study time. Domain 4 (Educational Strategies, 14%) warrants a moderate block, and Domain 6 (Resource Deployment, 6%) needs only a light review pass near the end of your prep window.
Assessment + Screening/Diagnosis/Care Planning
- Review geriatric assessment tools and how findings translate into care plans
Pharmacotherapy + Transitions of Care
- Drill polypharmacy scenarios and palliative/hospice transition triggers
Educational Strategies
- Practice matching education approaches to caregiver and patient constraints
Resource Deployment + full review
- Light pass on systems-based resource topics, then timed full-length practice
A full-length, timed practice run under exam-like conditions - 175 questions in four hours - is the single most useful thing you can do in the final stretch, since pacing errors are as likely to cost points as content gaps. For a structured walkthrough of this entire preparation process, see GS-C Study Guide 2026: How to Pass on Your First Attempt, and for a condensed last-minute reference, try the GS-C Cheat Sheet 2026: One-Page Review of Must-Know Facts.
