About this exam

The Advanced Oncology Certified Nurse Practitioner (AOCNP®) credential is offered by the Oncology Nursing Certification Corporation (ONCC), a certification body for nurses in oncology and related specialties. It is designed for advanced practice registered nurses - nurse practitioners - who manage patients with cancer across the care continuum, and it signals validated, current oncology knowledge to patients, employers, and interdisciplinary teams. ONCC describes certification as deepening knowledge and care across oncology and strengthening patient trust in cancer care.

The exam is multiple choice, and ONCC publishes practice tests built from the same item types and styles candidates will encounter on the real examination. Content spans the breadth of advanced oncology practice: the science of oncology; cancer prevention, detection, and diagnosis; treatment modalities; supportive, palliative, and end-of-life care; and survivorship and coordination of care. Expect items that test clinical decision-making within the APRN scope of practice rather than isolated recall.

Preparation works best as a staged plan: review ONCC's test resources and content outline first, take a practice test to find weak domains, then study by domain and re-test. ONCC's practice tests include the correct answer, rationale, and reference for every item, which makes them useful as learning tools rather than just score checks. Verify eligibility, deadlines, and scheduling directly with ONCC; this page is independent study material and is not affiliated with or endorsed by ONCC.

What you'll study

Common questions

About AOCNP preparation

What is the AOCNP® credential for?

It is ONCC's certification for advanced oncology nurse practitioners. ONCC describes certification as deepening knowledge and care across oncology and strengthening patient trust in cancer care. It is a professional credential demonstrating oncology expertise, not a license to practice, and eligibility and application requirements should be confirmed on ONCC's website.

What format is the exam?

Multiple choice. ONCC's practice tests mirror the type and style of items on the actual exam and include the correct answer, rationale, and reference for each item. The source material for this page does not publish the number of scored items or the appointment length, so confirm those details with ONCC before scheduling.

How long does application processing take?

ONCC states that, due to a high volume of test applications received, application processing may take up to 8 weeks. If 8 weeks have passed since you submitted your application and you have not received your Authorization to Test, ONCC advises contacting [email protected] directly.

What content areas does the exam cover?

Advanced oncology practice content: the science of oncology; cancer prevention, detection, and diagnosis; cancer treatment modalities; supportive, palliative, and end-of-life care; and survivorship and coordination of care. Study each area rather than concentrating on pharmacology or treatment alone, since broad coverage is the point of the credential.

How should I sequence my studying?

Take a practice test first to establish a baseline and identify your weakest domains. Study those domains from primary oncology references, then re-test to confirm the gap closed. Rotate back through stronger areas near the end so recall stays fresh, and always read the rationale for items you answered correctly by guessing.

How useful are ONCC's practice tests?

ONCC's AOCNP® Practice Test includes 100 multiple-choice items with the correct answer, rationale, and reference, randomly selected each time so items vary between uses. A free version includes 50 items in random order but the same items each time. Both reflect the type and style of items to expect on the actual exam.

How long do I have access to a practice test?

ONCC states you have 12 months from the date of purchase to start using the test. Once you access it, you can use it as many times as you like for 14 days. Because items change between uses, ONCC notes it is not necessary to purchase more than one practice test.

What is the most common study mistake?

Skipping the baseline practice test. Without it, you cannot tell which domains actually need work, and candidates often over-study areas they already handle well while neglecting supportive, palliative, and end-of-life care or survivorship and coordination of care, which carry equal weight in advanced practice.

How do I find retake, fee, and scoring policies?

Report those details only from ONCC directly. This page does not publish passing scores, fees, retake rules, or credential validity periods because they are not documented in the source material reviewed. Check the ONCC AOCNP® pages or contact [email protected] for current, authoritative figures.
