ACNPC-AG · ACCNS-AG
ACNPC-AG and ACCNS-AG are the AACN Certification Corporation's advanced-practice board exams for the adult-gerontology acute care population — one for nurse practitioners (AGACNPs), one for clinical nurse specialists. Passing is the gate state boards check before granting APRN licensure, and the credential hospitals and ICUs require to credential and privilege you. For a graduate who already finished an intense program and has a job offer pending, a single failed sitting can stall licensure and delay a start date by months. This page breaks down exactly what each exam tests, how it's delivered through PSI, and how to get it done right the first time.
Pay Only After You Pass
No upfront fee — you settle only after your verified passing result. We advertise guaranteed results — 100% pass guaranteed or money back.
Both certify the adult-gerontology acute care population — but for different APRN roles
| Credential | Code | APRN role | Practice focus |
|---|---|---|---|
| Adult-Gerontology Acute Care Nurse Practitioner | ACNPC-AG | Nurse Practitioner (AGACNP) | Diagnosing and managing acutely, critically, and complex chronically ill adult-gero patients |
| Adult-Gerontology Acute Care Clinical Nurse Specialist | ACCNS-AG | Clinical Nurse Specialist (CNS) | Wellness-through-acute-care continuum across the patient, nurse, and system spheres of influence |
Both exams are built and owned by AACN Certification Corporation, both contain 175 questions delivered over 3.5 hours, and both align with the APRN Consensus Model so the credential is accepted for licensure or designation in every U.S. state. The difference is the role: the ACNPC-AG tests the diagnostic and management decisions of an acute-care NP, while the ACCNS-AG tests CNS practice across the patient, nurse, and system spheres. Pick the exam that matches your graduate program track — they are not interchangeable.
How the ACNPC-AG and ACCNS-AG exams are built — at a glance
175
All multiple choice. 150 questions count toward your score; 25 are unscored pretest items being trialed for future forms. You cannot tell which is which during the exam.
3.5h
Three and a half hours of testing time. The exam is not computer-adaptive — every candidate answers a fixed-length form, so pacing across 175 items is a real skill to manage.
P/F
No fixed percentage. A panel of subject-matter experts and a psychometrician set a criterion-referenced cut score expressed as a raw number, and you get a pass or fail result.
On the NP exam, roughly 80% of items test clinical judgment in caring for the adult-gerontology patient — assessment, diagnosis, and the management plan — and about 20% test non-clinical knowledge such as professional caring, ethics, and systems across the lifespan. That heavy clinical-judgment tilt is why rote fact recall alone rarely carries a candidate over the line.
The CNS exam is also split into Clinical Judgment and Professional Caring & Ethical Practice, but it weights the non-clinical share more heavily — roughly 65% clinical judgment and 35% professional caring and ethical practice — reflecting CNS practice across the patient, nurse, and system spheres of influence. You are tested as much on how you change practice and systems as on bedside decisions, which catches NP-minded candidates off guard.
ACNPC-AG content emphasis — bars show each area's approximate share of scored items
Assessment, differential diagnosis, diagnostic testing, and the management plan for acutely, critically, and complex chronically ill adult-gero patients — by body system and presentation. The dominant share of the exam.
Professional caring and ethical practice, advocacy, collaboration, systems thinking, and the APRN role applied across the lifespan — the knowledge that frames safe, accountable advanced practice.
The ACCNS-AG uses the same two-section structure but shifts the weighting toward professional caring and ethical practice (about 35%, versus 20% on the NP exam), reflecting CNS practice across the patient, nurse, and system spheres. Whichever exam you sit, the questions are written as clinical scenarios that demand you choose the best next action — not simply recall a fact — so high-yield review must be paired with reasoning practice under time. Always confirm the current test plan in the official AACN exam handbook for your credential before you build a study plan.
Delivered through PSI — two ways to sit it, and what to expect on test day
AACN delivers the exam through PSI at more than 300 test sites across the U.S. You verify a government photo ID, store your belongings in a locker, and test on a provided workstation under camera and staff monitoring. Once your application is approved, you receive scheduling access and book an available appointment near you.
AACN also offers live remote proctoring (LRP) you take from a quiet, private location at home. You download PSI's secure lock-down browser, pass a system check, photograph yourself and your government ID, and complete a webcam room scan for a live proctor. No reference materials, second monitor, phone, or other person are permitted in the room for the full 3.5 hours.
AACN reviews your application and APRN program eligibility first. Once approved you get a link the same day to book your PSI appointment within the testing window.
A valid, unexpired government photo ID with a name matching your application. For online testing: a clear desk, closed door, no phone within reach, and a webcam room scan.
Stay on-camera and in frame for online sittings. Leaving the seat, talking aloud, or losing connection can flag or void the session. A preliminary pass/fail result appears at the end.
The credential that gates adult-gero acute care practice
Graduate APRN preparation is the entry requirement
Difficulty: The hard part is not memorizing facts — it is the 175 scenario-based items demanding the single best clinical action under hemodynamic instability, multi-system complexity, and time pressure, often on patients sicker than your clinical rotations covered. Candidates frequently report the breadth of acute-care presentations and the pacing across 3.5 hours as the real challenge, which is exactly the pressure point our help is designed to relieve.
The ACNPC-AG and ACCNS-AG sit between your finished APRN program and the licensure and credentialing that lets you actually start practicing.
