Board Prep · 5 min read · April 26, 2026
One of the first decisions every FNP candidate makes in the board prep process is which exam to take: the American Association of Nurse Practitioners (AANP) Family Nurse Practitioner Certification Exam, or the American Nurses Credentialing Center (ANCC) Family Nurse Practitioner Certification Exam. Both exams result in the same credential — board-certified FNP — and both are widely accepted by employers and state licensing boards. But they are different in important ways that affect how you prepare and which one is right for your situation.
The AANP exam consists of 150 questions (125 scored, 25 unscored pretest items) with a 3-hour time limit. The content is heavily weighted toward clinical knowledge — pathophysiology, pharmacology, diagnosis, and management — with a focus on primary care across the lifespan. The pass rate for the AANP exam has historically been around 85 to 88 percent for first-time takers.
The ANCC exam consists of 175 questions (150 scored, 25 unscored) with a 3.5-hour time limit. In addition to clinical content, the ANCC exam includes questions on professional role, health policy, research, and evidence-based practice. The pass rate for the ANCC exam has historically been slightly lower than the AANP, around 80 to 85 percent for first-time takers.
"The AANP exam is more clinically focused; the ANCC exam is broader. Neither is definitively harder — they test different things."
For most FNP candidates, the AANP exam is the better choice. Its clinical focus aligns more directly with the content of most FNP programs, the preparation is more straightforward, and the pass rate is slightly higher. The AANP certification is accepted by virtually all employers and state licensing boards, and there is no meaningful career advantage to holding ANCC certification over AANP certification in most practice settings.
The ANCC exam may be the better choice for candidates who are particularly strong in the non-clinical content areas it tests — health policy, research, professional role — or who are applying to positions that specifically require ANCC certification (some academic and federal positions have this requirement).
The core clinical content tested on both exams is largely the same, and the preparation strategies that work for one work for the other. The primary difference in preparation is the additional content areas tested by the ANCC — which require additional study time if you choose that exam.
