According to Oncology Nursing Certification Corporation, “ONCC examinations are offered by computer-based testing at more than 1,500 PSI test centers worldwide, including hundreds of test centers in the United States.”[1]
The Advanced Oncology Certified Nurse Practitioner (AOCNP) exam is the ONCC certification test for nurse practitioners in oncology care. If you pass, your certification is valid for 4 years.
Delivery and timing: ONCC exams are computer-based and offered at more than 1,500 PSI test centers worldwide. A test session lasts 3 hours. That time includes a 15-minute computer-based testing tutorial before the exam and a post-test survey, so you have a little less than the full session for the questions.
Fees and retakes: The fee is $420 for nonmembers and $300 for ONS/APHON members. There is also an optional $100 DoubleTake fee that covers a retake. You can only buy it at the time of your initial application, so decide before you apply. Check ONCC for the full DoubleTake terms.
Results: You see your result on screen as soon as you finish the exam. An email with printable results arrives within 1 hour of testing. The passing standard and how scores are reported are explained in the ONCC Test Registration Manual.
Eligibility and location: ONCC sets the eligibility requirements, and this page does not repeat them. Confirm them on the official AOCNP page at oncc.org before you apply. Candidates outside the United States, its territories and Canada follow a separate international process. ONCC expects applications for 2027 international testing to open January 1, 2027.

Prepare for the AOCNP - Advanced Oncology Certified Nurse Practitioner exam with our free practice test modules. Each quiz covers key topics to help you pass on your first try.
These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.
Question: Which validated screening tool is most widely recommended for identifying nutritional risk in hospitalized oncology patients?
Answer: B. NRS-2002 (Nutritional Risk Screening 2002) or MUST (Malnutrition Universal Screening Tool)
Explanation:
B is correct. NRS-2002 and MUST are validated screening tools built for exactly this job: finding which patients are at nutritional risk. They combine weight status, recent unintended weight loss, reduced intake and illness severity, so they catch patients that any lone measure would miss.
Rule: screen with a validated multi-factor tool, then assess. Never rely on a lone lab value or body measure.
Question: A patient is diagnosed with acute promyelocytic leukemia (APL, AML-M3). Which agent is a cornerstone of induction therapy that induces differentiation of malignant promyelocytes?
Answer: C. All-trans retinoic acid (ATRA)
Explanation:
C is correct. APL is driven by the PML-RARA fusion protein, which stops promyelocytes from maturing. ATRA acts on this abnormal retinoic acid receptor and lets the cells differentiate. That is why it is a cornerstone of induction, given with arsenic trioxide or an anthracycline.
Rule: in APL, think differentiation therapy first, and watch for differentiation syndrome after ATRA starts.
Question: An oncology NP suspects a colleague is documenting chemotherapy administration that was not actually performed. Which action represents the NP's primary professional and legal obligation?
Answer: B. Report the concern through the institution's established reporting chain or compliance office
Explanation:
B is correct. Documenting chemotherapy that was not given is falsification of the medical record. It can be healthcare fraud, and it puts patients at risk. The NP's duty is to report the concern without delay through the institution's established channels, such as a manager, the compliance office, a hotline or risk management.
Rule: when patient safety or record integrity is at stake, report through formal institutional channels. Do not investigate or settle it informally on your own.

An ONCC test session is 3 hours. That time includes a 15-minute computer-based testing tutorial before the exam and a post-test survey at the end, so the time you have for the questions is a little shorter than the full session. Plan your pacing with that in mind, and check the ONCC Test Registration Manual for the current test-day rules.
The fee is $420 for nonmembers and $300 for ONS/APHON members. ONCC also offers an optional $100 DoubleTake fee that covers a retake. You can only buy it at the time of your initial application, not later, so decide whether you want it before you submit. Confirm current fees in the ONCC Test Registration Manual.
Right away. ONCC shows your result on screen as soon as you finish the exam. Within 1 hour of testing you also get an email with printable results. You do not need to wait for a mailed score report to know whether you passed. Details on how scores are reported are in the ONCC Test Registration Manual.
The exam is computer-based and given at PSI test centers. ONCC says its exams are offered at more than 1,500 PSI test centers worldwide, including centers across the United States. You choose a center and schedule your appointment after ONCC approves your application. Check the ONCC Test Registration Manual for the scheduling steps.
After you pass, your AOCNP certification is valid for 4 years. ONCC sets the renewal requirements and options, which can change, so check the official AOCNP page on oncc.org well before your certification period ends. Keeping records of your practice and learning while certified makes renewal easier.
Yes, through ONCC's international testing process for candidates outside the United States, its territories and Canada. ONCC expects applications for 2027 international testing to open January 1, 2027. Rules and timing for international candidates differ from those for US candidates, so read ONCC's page for candidates outside the United States before you plan your exam date.
