One of the first decisions every FNP student makes is one that almost nobody warns them about in school: which boards exam are you going to take? You have two choices — the AANP (American Academy of Nurse Practitioners) and the ANCC (American Nurses Credentialing Center). Both certify you as a Family Nurse Practitioner. Both are recognized by all 50 states. Both will get you the credential after your name.
But they are not the same test, and choosing the wrong one for your brain can cost you weeks of study time and a few thousand dollars in retake fees. Let's break it down honestly.
The best boards exam is the one that matches how you actually think. Not the one your classmate took.
The AANP Exam at a Glance
The AANP FNP exam is 150 multiple-choice questions, 135 scored and 15 pretest. You have 3 hours. The content focuses almost entirely on clinical content — assessment, diagnosis, planning, and evaluation. You will not see questions about nursing theory, research methodology, or policy. It's a clinical exam.
The breakdown is roughly:
- Assessment — about 36%
- Diagnosis — about 24%
- Planning — about 23%
- Evaluation — about 17%
Patient populations span all ages: prenatal, pediatric, adolescent, adult, and geriatric.
The ANCC Exam at a Glance
The ANCC FNP exam is 175 questions, 150 scored and 25 pretest. You have 3.5 hours. The content includes clinical material but also a meaningful percentage of non-clinical content: professional role, ethics, research, healthcare policy, evidence-based practice, and cultural awareness.
The breakdown:
- Assessment and Diagnosis — about 38%
- Planning and Implementation — about 31%
- Evaluation — about 16%
- Professional role and policy — about 15%
How to Choose Between Them
Here's the rough rule I give my students.
Take the AANP if you are a clinical thinker who wants the test to ask you what you'd actually do for a patient. If pathophysiology and pharmacology are your stronger areas, and theory makes your eyes glaze, AANP is more friendly.
Take the ANCC if you remember loving (or at least tolerating) nursing theory in school. If you want a slightly longer test with more variety, and you don't mind questions about Magnet hospitals, evidence-based practice models, and cultural competence theory, ANCC may suit you.
About 70% of my students take AANP for the simple reason that they want a clinical test. About 30% take ANCC. Pass rates are similar — both around 85% — and that small difference is mostly about who self-selects into each one.
Practical Pearl: Whichever exam you take, the underlying content overlaps about 75%. So most of your study material works for either. The differentiator is the final 25%.
Cost and Logistics
Both exams cost roughly $300 to $400 depending on AANP membership status. Both are computer-based and proctored at Prometric or PSI testing centers. Both allow retakes if you fail, with specific waiting periods (usually 60 days).
You apply, get an Authorization to Test (ATT), schedule at a testing center, and sit. The application processing time can be a few weeks, so plan ahead — don't wait until you finish school to start the paperwork.
Study Resources That Work for Both
- Fitzgerald's Family Nurse Practitioner Certification Review
- Leik's Family Nurse Practitioner Certification Review
- Hollier's Clinical Guidelines in Primary Care
- A solid question bank — and yes, Rubio Board Review's FNP bank is built specifically for both exams
Whichever resource you pick, do questions every day. Reading review books cover to cover without question practice is the single most common preparation mistake I see.
One Last Word
Pick the exam that matches your brain. Stop scrolling Reddit for opinions. Take a 50-question diagnostic from each style — both AANP and ANCC have practice tests available — and notice which one felt more like home. Then commit. The decision matters less than the consistency that follows it.
You'll pass either one if you do the work. And the work is the same either way.
