What the ONN-CG Credential Actually Is
The Oncology Nurse Navigator-Certified Generalist (ONN-CG) is the certification offered by the AONN+ Foundation for Learning (AONN+ FFL) for registered nurses who work as oncology nurse navigators. It is a generalist credential, which means it tests the breadth of the navigator role rather than expertise in a single tumor type or treatment modality. If you are still orienting yourself to the terminology, our explainers on what ONN-CG is and what ONN-CG stands for cover the basics.
The exam is built around the real work of navigation: moving patients through a fragmented system, advocating for them, connecting them to psychosocial resources, and improving the programs that serve them. That emphasis shapes both the question content and how you should prepare. For a broader overview of the credential itself, see our page on what ONN-CG certification is.
Who Qualifies to Sit for the Exam
The eligibility requirements are practical rather than academic. AONN+ FFL asks for evidence that you are a working navigator, not just someone who has studied navigation. Candidates must document:
- An active RN license in good standing
- Current employment in navigation, with at least three years of direct navigation experience
- 15 navigation continuing education credits earned in the preceding 12 months, with no more than five of those credits coming from Tumor Board attendance
- A curriculum vitae
- Your current employer job description
- An employer-signed reference
A BSN is not required, which opens the door to experienced navigators who built their careers on an associate degree or diploma. The Tumor Board cap matters when you plan your CEs: if you attend tumor boards weekly, you will still need most of your 15 credits from other navigation-focused education. A fuller walkthrough lives in our guide to ONN-CG requirements and how to qualify.
Key Takeaway
Start your documentation early. The employer-signed reference and current job description depend on other people's calendars, and your CE window is a rolling 12 months, so verify that your 15 credits fall inside it at the time you apply.
Exam Format: Paper, Pencil, and Three Hours
The ONN-CG is delivered as an in-person, paper-and-pencil examination in English. A remote or electronic option is not currently established by the sources reviewed for this article, so do not plan around testing from home or at a commercial computer-based center.
| Feature | ONN-CG Detail |
|---|---|
| Issuer | AONN+ Foundation for Learning (AONN+ FFL) |
| Delivery | In person, paper and pencil |
| Language | English |
| Questions | 120 multiple choice |
| Testing time | Three hours |
| Reference materials | Closed book |
| Scheduled breaks | None; permitted individual breaks do not stop the timer |
Three hours for 120 questions averages out to 90 seconds per item. The absence of scheduled breaks, and the fact that a personal break does not pause the clock, means you should practice sitting through the full duration. Paper formats also change test-day habits: you can flip back to earlier questions and mark items on the page, but you must manage your own pacing without an on-screen timer or flagging tool. Our ONN-CG difficulty guide discusses how the format and question style affect perceived difficulty.
Questions are scenario-oriented, reflecting what navigators do daily: a patient missing appointments, a transition from active treatment to survivorship, a barrier to care that needs an advocacy response. Expect to choose the best navigator action rather than simply recall a definition. When you want to rehearse that style, the ONN-CG practice tests on our main site are built for exactly this kind of decision-based question.
Fees, Application Timing, and Results
The initial examination fee depends on membership:
- USD 150 for AONN+ National Members
- USD 300 for non-members
Because the member/non-member gap is USD 150, the math on joining before you apply is usually straightforward, though you should compare the current membership cost yourself. Our ONN-CG certification cost breakdown lays out the full set of expenses to budget.
Application deadline and results
The candidate handbook requires you to apply at least 30 days before an approved examination date, and individual sessions can set their own deadlines on top of that. Treat the earlier of the two as your real deadline.
For results, the handbook allows up to 45 business days. The announcement for the 2026 conference session cites six weeks for that session. Plan for the longer window if you have a job decision, a contract renewal, or a promotion conversation that depends on the outcome.
The Eight Weighted Domains
The exam blueprint contains eight official weighted domains that total 100%. These are the actual exam objectives, not just handy study headings. The weights tell you where the points are, and the distribution is notably uneven. For a deeper domain-by-domain treatment, see our complete guide to all eight ONN-CG content areas.
| 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% |
Domain 2: Coordination of Care/Care Transitions (27%)
The single largest domain, and the one that most closely mirrors daily navigation work. Expect questions about moving patients between diagnosis, treatment, and follow-up, and between settings and teams.
- Handoffs between primary care, specialists, treatment centers, and community resources
- Tracking patients through the continuum so that no step falls through the gaps
- Care transitions, including shifts in setting and shifts in treatment intent
- Interdisciplinary communication and your role relative to physicians, social workers, and other staff
Domain 3: Patient Advocacy/Patient Empowerment (21%)
The second-largest domain. Questions test whether you can identify barriers and respond in a way that strengthens the patient's own voice rather than simply acting on their behalf.
- Recognizing and addressing barriers to care
- Supporting informed decision-making and patient self-advocacy
- Navigating system, access, and communication obstacles
- Distinguishing empowerment from taking over
Domain 5: Survivorship/End of Life (13%)
This domain spans both ends of the cancer trajectory after active treatment decisions. Candidates sometimes underweight it because it feels less procedural, but at 13% it outweighs several operational topics combined.
- Transitions to survivorship and ongoing follow-up needs
- Palliative and end-of-life considerations in a navigator's scope
- Supporting patients and families through changing goals of care
Domain 4: Psychosocial Support Services/Assessment (10%)
Covers identifying emotional, social, practical, and financial needs and connecting patients to the right services.
- Screening and assessing for psychosocial need
- Referral pathways to counseling, financial assistance, and support resources
- Recognizing when a concern exceeds the navigator's role and needs escalation
The smaller domains still matter
Community Outreach/Prevention (9%) covers the navigator's role in education, screening promotion, and reaching underserved populations. Professional Roles and Responsibilities (8%) addresses scope, ethics, and professional conduct. Quality and Performance Improvement (7%) asks you to think about metrics and program improvement, and Operations Management (5%) covers the administrative side of running a navigation program. Together these four domains account for 29% of the exam. Skipping them to double down on the big two is a common and costly mistake.
Scheduling: What the Official Sources Show
Exam dates are the part of this credential most likely to confuse candidates, because the official pages do not all agree. As of the check on October 15, 2026:
- The Apply Here page still displayed November 2025 sessions and an October 10, 2025 deadline, which is stale.
- The 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 set an October 1, 2026 application deadline and states there is no onsite registration.
Practically, that means candidates should build their plan around the next announced session rather than a date they hope will be extended. Keep an eye on the issuer's pages, and see our running summary of ONN-CG exam dates, deadlines, and scheduling for updates. Remember the handbook's 30-day minimum, and work backward from the deadline, not the exam day.
Sequencing Your Preparation Around the Blueprint
Rather than a generic schedule, let the blueprint weights drive the order. This sequence front-loads the heaviest domains while saving the smaller ones for the weeks when repetition helps most. For a broader methodology, our ONN-CG study guide goes deeper.
Coordination of Care/Care Transitions (27%)
- Map the full patient journey from screening through treatment and follow-up
- Practice scenario questions on handoffs and tracking
- Review your own program's navigation workflow against textbook models
Patient Advocacy/Patient Empowerment (21%)
- Catalog common barriers and the best navigator response to each
- Drill the difference between empowering a patient and acting for them
Survivorship/End of Life (13%) and Psychosocial Support (10%)
- Review survivorship transitions and palliative scope
- Study screening tools and referral pathways
Smaller domains and timed practice
- Cover Community Outreach, Professional Roles, Quality, and Operations
- Complete a full 120-question, three-hour paper-style session without breaks
Spend the closing days on weak spots from your practice results. A one-page recap such as our ONN-CG cheat sheet is useful for a final skim, and the practice question bank on our main site lets you check your readiness against realistic scenarios. If you want to understand how hard to expect the exam to be and what a numerical cutoff might mean, see our pages on the passing score and the pass rate; note that a verified numerical passing threshold and pass rate were not available in the sources reviewed.
Retesting and Renewal
If you do not pass
Unsuccessful candidates must wait at least six months before retesting, and the retest fee is USD 45. The six-month wait is long enough that you should treat a first attempt seriously rather than as a trial run. Use the interval to rebuild around the domains where you were weakest.
Maintaining the credential
Certification lasts three years. Renewal requires:
- 45 continuing education credits over the 36-month period
- Continued RN good standing
- An updated CV
- A signed recommendation
- Your job description
- Payment
Practically, keep every CE certificate from day one of your certification cycle, and do not wait until the final year to discover how many of your credits count.
Where the Credential Fits in Your Career
ONN-CG holders typically work in settings where oncology navigation is a defined role: hospital cancer centers, community oncology practices, comprehensive cancer programs, and health systems building out navigation services. The credential is a signal to employers that you have documented experience and have demonstrated command of the navigator competencies tested on the exam. Whether it translates into a raise or a promotion depends on your employer, so avoid assuming a pay bump. For a realistic picture, read our salary guide and our worth-it analysis, or browse the roles described on our ONN-CG jobs page.
Key Takeaway
Because eligibility requires three years of hands-on navigation, the credential works best as a formal recognition of experience you already have. Use your daily cases as study material: nearly every large domain on the blueprint corresponds to something you handle weekly.
