What This Exam Actually Is (and Isn't)
The Oncology Nurse Navigator-Certified Generalist (ONN-CG) is a credential offered by the AONN+ Foundation for Learning (AONN+ FFL), the education and certification arm connected to the Academy of Oncology Nurse & Patient Navigators. It is built for registered nurses who work as oncology nurse navigators across the cancer continuum, not for a single disease site or a single care setting.
Before you buy a single study resource, make sure you are preparing for the right credential. This guide covers only the Oncology Nurse Navigator-Certified Generalist from AONN+ FFL. It is not OPN-CG, not ONN-CG(T), and not ONCC's OCN. Those are different credentials with different eligibility rules, formats and content outlines. If you need a primer on the title itself, see What Is ONN-CG? or What Does ONN-CG Stand For?.
The word "Generalist" matters for studying. The exam tests navigation practice: how you coordinate, advocate, assess, educate and improve systems. It is not a clinical oncology nursing exam that quizzes you on chemotherapy dosing or tumor staging minutiae. Clinical knowledge supports your answers, but the questions are framed around what a navigator does.
Format, Timing and Test-Day Logistics
The issuer administers the examination in person, using paper and pencil, in English. The sources reviewed do not establish a remote or electronic route, so do not plan around one. Here is what the format means in practice:
| Feature | ONN-CG Detail | What It Means for You |
|---|---|---|
| Questions | 120 multiple choice | Practice selecting the best answer among plausible options |
| Time | Three hours | Average pace is well under 1.5 minutes per question, leaving a review buffer |
| Delivery | In person, paper and pencil | Practice bubbling answers and marking questions in a booklet |
| References | Closed book | No notes, no looking up policy language |
| Breaks | None scheduled; individual breaks permitted but the timer keeps running | Treat a restroom trip as lost exam time |
| Language | English | Exam terminology is in English only |
Paper-and-pencil delivery changes your strategy. You cannot rely on software flagging, but you can skip and return within the booklet. A sensible approach is a first pass that answers everything you are confident about, a second pass for the questions you marked, and a final scan to confirm every answer was recorded in the right place.
For a realistic look at how demanding the format feels, read How Hard Is the ONN-CG Exam?, and use our ONN-CG practice tests to rehearse the timing.
Eligibility and Application Mechanics
Many candidates lose weeks because they treat the application as an afterthought. Per the issuer's materials, you need:
- An active RN license in good standing.
- Current employment in navigation and at least three years of direct navigation experience.
- 15 navigation continuing education credits earned in the preceding 12 months, with a maximum of five from Tumor Board attendance.
- A current CV.
- Your current employer job description.
- An employer-signed reference.
A BSN is not required. That is a meaningful difference from credentials that gate eligibility by degree level. Our ONN-CG Requirements guide walks through qualifying in more detail.
The Tumor Board cap deserves attention. Only five of your 15 CEs may come from Tumor Board attendance, so the remaining ten must come from other navigation-relevant education. If you attend a tumor board weekly, do not assume that alone covers your CE requirement.
Reading the Blueprint: Where the Points Live
The exam is organized around eight official weighted exam-objective domains totaling 100%. These are the actual scored objectives, not just preparation headings. The blueprint appears in the live AONN+ FFL exam blueprint and on printed page 4 of the 2024 ONN-CG Candidate Handbook.
| Domain | Weight |
|---|---|
| 1. Community Outreach/Prevention | 9% |
| 2. Coordination of Care/Care Transitions | 27% |
| 3. Patient Advocacy/Patient Empowerment | 21% |
| 4. Psychosocial Support Services/Assessment | 10% |
| 5. Survivorship/End of Life | 13% |
| 6. Professional Roles and Responsibilities | 8% |
| 7. Operations Management | 5% |
| 8. Quality and Performance Improvement | 7% |
Two domains account for 48% of the exam. Add Survivorship/End of Life at 13% and Psychosocial Support at 10%, and four domains cover 71% of what you will see. That is where your study hours should concentrate.

Domain-by-Domain Mastery Notes
The official sources define the domains and weights; the notes below describe the kinds of navigation competencies these domain names point to. Always confirm specific task statements against the current blueprint and candidate handbook.
Domain 2: Coordination of Care/Care Transitions (27%)
This is the heaviest domain, and it is the heart of the navigator role. Expect scenario questions about moving a patient through the cancer care pathway without gaps.
- Handoffs between diagnosis, treatment, surgery, radiation, supportive care and follow-up.
- Communicating across multidisciplinary teams and community providers.
- Identifying delays and closing loops on referrals, scheduling and test results.
- Transitions between settings, such as hospital to home or active treatment to surveillance.
Domain 3: Patient Advocacy/Patient Empowerment (21%)
Questions in this domain typically test your judgment about whose voice drives decisions and how a navigator supports it.
- Supporting informed decision-making without substituting your own preferences.
- Helping patients communicate with their care team and understand options.
- Addressing barriers such as access, insurance, language and health literacy.
- Recognizing when to escalate concerns on a patient's behalf.
Domain 5: Survivorship/End of Life (13%)
This domain spans two ends of the continuum. Study them together because exam scenarios often test whether you can match navigation actions to the patient's phase of care.
- Survivorship care planning, late and long-term effects, and surveillance follow-up.
- Palliative care and hospice referral, goals-of-care conversations and support for families.
Domain 4: Psychosocial Support Services/Assessment (10%)
Know how navigators identify and respond to non-medical needs that affect treatment.
- Distress screening and appropriate referral pathways.
- Financial, transportation, housing and caregiver-related barriers.
- Connecting patients with social work, counseling and community resources.
Domain 1: Community Outreach/Prevention (9%)
Navigation does not begin at diagnosis. Review how navigators support screening, education and access in the community, including reaching underserved populations.
Domains 6, 7 and 8: Professional Roles, Operations Management, Quality and Performance Improvement (8%, 5%, 7%)
Together these make up 20% of the exam. They are easy to neglect because they feel less clinical, but they are often where candidates with strong bedside backgrounds lose points.
- Scope of the navigator role, professional boundaries and ethical practice.
- Program operations, such as workflows, resources and metrics.
- Quality improvement concepts and using data to improve navigation outcomes.
A Blueprint-Weighted Study Sequence
Rather than a generic template, sequence your preparation by domain weight and by how much each area differs from your daily work. If your job is heavily weighted toward treatment coordination, you may already have a head start on Domain 2 and need extra time on operations and quality. Adjust accordingly. The example below assumes an eight-week window.
Coordination of Care/Care Transitions
- Read the handbook blueprint line by line and mark unfamiliar task statements.
- Work scenario questions on handoffs, referral tracking and care pathways.
- Take a short baseline quiz to find weak spots.
Patient Advocacy and Psychosocial Support
- Review advocacy and empowerment scenarios, focusing on best-answer reasoning.
- Study distress screening, barrier assessment and referral logic.
Survivorship/End of Life and Community Outreach/Prevention
- Cover survivorship planning and palliative and end-of-life navigation.
- Review prevention, screening and outreach concepts.
Professional Roles, Operations Management, Quality
- Close gaps in the three smallest-weighted but least familiar domains.
- Practice interpreting basic quality and performance concepts.
Full-length timed practice
- Sit a complete 120-question simulation in three hours, without breaks or notes.
- Review every miss by domain and revisit the 27% and 21% areas first.
When you reach the final stretch, a condensed reference like the ONN-CG Cheat Sheet helps with last-minute review, and the main practice test site lets you simulate the full exam under timed conditions. For the bigger picture of how everything fits together, return to our ONN-CG Study Guide hub.
Costs, Timelines and the Retake Rule
Budget before you apply. The initial examination fee depends on membership:
- AONN+ National Member: USD 150
- Non-member: USD 300
Membership in a Local Navigator Network alone does not qualify you for the discounted fee. Only AONN+ National Membership does, so check which membership you actually hold before you assume the lower price. For the full financial picture, including renewal, see ONN-CG Certification Cost: Complete Pricing Breakdown.
Results timing: The handbook allows up to 45 business days for results. The 2026 conference announcement gives six weeks for that session. Plan on waiting rather than expecting immediate scoring.
If you do not pass: Unsuccessful candidates must wait at least six months before retesting, and the retest fee is USD 45. A six-month gap is a long time, which is a strong reason to treat your first attempt seriously and to schedule only when your timed practice scores are stable.
The 2026 Testing Session: What to Know
Scheduling information on the issuer's websites is not fully consistent, so verify before you commit. The "Apply Here" page still displayed November 2025 sessions and an October 10, 2025 deadline when checked. A newer AONN+ Annual Conference announcement lists ONN-CG testing on November 11, 2026, from 8:30 to 11:30 a.m., at the Gaylord Texan Resort & Convention Center in Grapevine, Texas. That announcement gives an October 1, 2026 application deadline and states there is no onsite registration.
That deadline had already passed when the information was checked on October 15, 2026, so this session should not be treated as open for new applications. If you are reading this and aiming for certification, plan for the next available session and confirm dates directly with AONN+ FFL. The registration page linked from the conference announcement returned no readable public content when checked, so we do not infer any checkout details from it. Our ONN-CG Exam Dates guide tracks scheduling updates.
Key Takeaway
Work backward from a verified session: confirm the date with the issuer, apply at least 30 days ahead (earlier if the session deadline is sooner), and give yourself time to collect your employer-signed reference and job description.
After You Pass: Certification Life Cycle
Certification lasts three years. Renewal requires 45 continuing education credits over the 36-month period, continuing RN good standing, an updated CV, a signed recommendation, your job description and payment.
Because the CE rules are tight, start tracking navigation-relevant education from your first day of certification rather than scrambling in year three. If you are weighing the career value, our guides on whether the certification is worth it, earnings and ONN-CG jobs cover the employer side. Cancer centers, hospital oncology programs and community oncology practices that employ nurse navigators are the typical settings where this credential is relevant.
Frequently Asked Questions
The exam has 120 multiple-choice questions and three hours of testing time. It is closed-book, in person, paper-and-pencil and in English, with no scheduled breaks. Individual breaks are allowed but do not stop the clock.
No. A BSN is not required. You need an active RN license in good standing, current navigation employment, at least three years of direct navigation experience, 15 navigation CEs from the preceding 12 months, a CV, your job description and an employer-signed reference.
Start with Coordination of Care/Care Transitions at 27% and Patient Advocacy/Patient Empowerment at 21%, which together are 48% of the blueprint. Then cover Survivorship/End of Life (13%) and Psychosocial Support Services/Assessment (10%) before the smaller domains.
You must wait at least six months before retesting, and the retest fee is USD 45. Because of that delay, it is wise to confirm readiness with full-length timed practice before your first attempt.
The conference announcement lists a November 11, 2026 session with an October 1, 2026 application deadline and no onsite registration. That deadline had passed when checked, so do not plan on it. Confirm upcoming sessions directly with AONN+ FFL.
Passing on your first attempt comes down to matching your preparation to the blueprint, handling the application paperwork early, and rehearsing the exact conditions of a closed-book, three-hour paper exam. Use the ONN-CG Exam Prep practice tests to build that familiarity before test day.
