Every question includes a clear explanation so you learn the reasoning, not just the answer.

The OCN exam — the Oncology Certified Nurse credential — is administered by the Oncology Nursing Certification Corporation (ONCC) and is the most widely recognized certification for adult oncology nurses.[1] These free OCN practice questions and test prep mirror the current OCN Test Content Outline so you practice the way the real exam is built.[5] For deeper review, pair these with our free study guide, flashcards.

What Is on the OCN Exam?

The OCN exam covers six knowledge domains: Symptom Management and Supportive Care (25%), Treatment Modalities (20%), Oncologic Emergencies (16%), Oncology Nursing Practice (15%), Care Continuum (14%), and Psychosocial Dimensions of Care (10%).[1]

Symptom Management is the single largest section, and together with Treatment Modalities and Oncologic Emergencies it accounts for more than 60% of scored questions. Our full practice test is weighted to match:

Practice Questions by Domain

Use Start Test for a full weighted OCN simulation, or open the hub and pick a single domain to drill your weak area. After each full exam, your results show a per-domain breakdown so you know exactly where to focus — most candidates need the most reps on symptom management and oncologic emergencies.

What Are the Requirements to Take the OCN?

To take the OCN exam, you must hold a current, active, unencumbered RN license, complete at least 2,000 hours of adult oncology nursing practice within the prior four years (with a minimum of two years of RN experience in that window), and earn at least 10 contact hours of oncology continuing education within the prior three years.[1]

Documentation may be requested during an eligibility audit.

How Do You Register for the OCN Exam?

You register for the OCN by applying online through the ONCC website; once your application and eligibility documentation are approved, ONCC issues an eligibility notice and you schedule the exam at an approved testing center or via online proctoring within your 90-day testing window.[3]

The exam fee is $300 for ONS or APHON members and $420 for non-members, so joining before applying can offset much of the membership cost.

What Is the Passing Score for the OCN?

The passing score for the OCN is a scaled score of 55, on a scale that runs from 25 to 75.[2] The OCN converts your raw number-correct score to that scaled score, and only 145 of the 165 questions count — the other 20 are unscored pretest items.

ONCC uses statistical equating so candidates taking different exam forms are evaluated on an equivalent standard. Preliminary pass/fail results are typically provided at the test center immediately after you finish, with an official report following.

How Hard Is the OCN? (Pass Rate)

The OCN is challenging — recent first-attempt pass rates have hovered in the low-to-mid 60% range (commonly cited around 62%), placing it among the more demanding nursing specialty exams.[4] The breadth of oncology content is large, and most questions are written at the application and analysis level rather than simple recall.

The takeaway: drill until you’re consistently scoring above target on full-length practice — especially symptom management and oncologic emergencies — before you book your exam date.

What to Expect on Exam Day

Arrive at your testing center at least 15 minutes early to check in — bring a valid, unexpired government-issued photo ID whose name matches your ONCC application.[3]You’ll store phones and personal items before testing; no notes are allowed.

A short tutorial precedes the exam, then you have 3 hours to answer 165 multiple-choice questions. Most questions are scenario-based and ask for the best nursing action. If you test via online proctoring, expect a similar room scan and ID check.

ONCC typically provides preliminary pass/fail results at the center, with an official report to follow. Having simulated the full timing with practice tests makes that clock feel routine.

How to Use This OCN Practice Test

  • Recreate exam conditions. Take the full test timed, with no notes.[5]
  • Diagnose, then drill. Use a full OCN simulation to find weak domains, then drill them.
  • Prioritize symptom management + emergencies. They’re the biggest score-movers.
  • Learn the why. Read every explanation — understanding beats memorizing.
  • Think clinically. Most items ask for the best nursing action, not a single fact.

Why Get OCN Certified?

The OCN credential is the most widely recognized oncology nursing certification, often preferred by employers and tied to higher pay, advancement, and validated clinical expertise.[1] These free OCN practice tests are the most efficient way to get there.

Conclusion

Passing the OCN comes down to applied clinical judgment across symptom management, treatment modalities, and oncologic emergencies. Use this free OCN practice test to find your weak domains, drill them to mastery, and walk in confident on test day. Then reinforce what you learn with our study guide, flashcards.
