What Is ONN-CG?

TL;DR
  • ONN-CG stands for Oncology Nurse Navigator-Certified Generalist, issued through the AONN+ Foundation for Learning.
  • The exam is in-person, paper-and-pencil, closed-book: 120 multiple-choice questions in three hours with no scheduled breaks.
  • Applicants need an active RN license, current navigation employment and at least three years of direct navigation experience.
  • Coordination of Care/Care Transitions (27%) and Patient Advocacy/Patient Empowerment (21%) together make up nearly half the blueprint.

The Credential in Plain Terms

ONN-CG is the abbreviation for Oncology Nurse Navigator-Certified Generalist. It is a professional certification for registered nurses who work as oncology nurse navigators: the clinicians who guide patients and families through diagnosis, treatment, survivorship and sometimes end of life, removing barriers and coordinating the many hands involved in cancer care.

The word "Generalist" matters. The credential tests navigation practice across the whole cancer continuum rather than a single tumor type or treatment modality. That is why its blueprint reaches from community outreach and prevention on one end to survivorship and end-of-life care on the other, with operations and quality improvement woven in. If you are comparing the many pages that explain this term, the site also covers related phrasing in What Does ONN-CG Stand For? and ONN-CG Meaning.

One acronym, several credentials: The letters "ONN-CG" are not unique in the wider healthcare world, and neighboring credentials such as OPN-CG, ONN-CG(T) and the OCN from a different certifying body are separate programs with their own rules. Everything in this article refers only to the Oncology Nurse Navigator-Certified Generalist offered through AONN+ Foundation for Learning. Do not apply fees, dates or eligibility rules from a different credential to this one.

Who Issues It and What the Name Tells You

The certification is administered by AONN Foundation for Learning, Inc., branded as the AONN+ Foundation for Learning (AONN+ FFL), the educational arm associated with the Academy of Oncology Nurse & Patient Navigators. That affiliation shapes the exam in a practical way: the content reflects navigation as a defined professional role, not a repackaged bedside oncology nursing test.

Reading the full name left to right is a useful memory aid:

  • Oncology: the practice setting is cancer care.
  • Nurse Navigator: the role is navigation, not direct treatment delivery.
  • Certified Generalist: the scope is broad, covering the full continuum.

For a deeper look at how this credential is described across the site, see ONN-CG Certification and What Is ONN-CG Certification?.

What the Exam Looks Like

The format is more traditional than many candidates expect. Based on the issuer's published materials, the examination is administered in person, on paper, in English, with 120 multiple-choice questions and three hours of testing time. It is closed-book, and there are no scheduled breaks. Individual breaks are permitted, but the clock keeps running while you step away. A remote or electronic delivery route is not currently established in the sources reviewed.

Question count120 multiple-choice questions
Time allowedThree hours
ResourcesClosed-book
BreaksNone scheduled; individual breaks do not stop the timer

Three hours for 120 questions averages out to roughly 90 seconds per item, which is comfortable for recall questions but tight for long scenario stems. Because the test is on paper, you cannot flag and revisit questions with a software button; you will rely on your own marks in the booklet and a deliberate pacing plan. Practicing with timed sets, including the kind on the ONN-CG practice test site, helps you build that rhythm before test day.

Questions typically place you in a navigator's seat: a patient with a transportation barrier, a care transition between settings, a distress screening result, a survivorship care plan gap. You choose the best navigation action. Expect the reasoning to be practice-based rather than purely definitional. For an honest view of difficulty, read How Hard Is the ONN-CG Exam?.

The Eight Weighted Domains

The exam blueprint contains eight official weighted exam-objective domains that total 100%. These are the actual content categories the exam draws from, not just headings in a prep curriculum. The weights tell you where your study hours will pay off most.

DomainNameWeight
1Community Outreach/Prevention9%
2Coordination of Care/Care Transitions27%
3Patient Advocacy/Patient Empowerment21%
4Psychosocial Support Services/Assessment10%
5Survivorship/End of Life13%
6Professional Roles and Responsibilities8%
7Operations Management5%
8Quality and Performance Improvement7%

Domain 2: Coordination of Care/Care Transitions (27%)

The heaviest domain and the heart of the role. Expect questions about moving patients smoothly between diagnosis, treatment, supportive care and follow-up.

  • Tracking referrals and closing loops between providers
  • Handoffs between clinical settings and between teams
  • Anticipating delays and barriers before they derail treatment
  • Working within a multidisciplinary team

Domain 3: Patient Advocacy/Patient Empowerment (21%)

The second-largest domain focuses on helping patients understand options and participate in decisions.

  • Supporting informed decision-making without steering it
  • Addressing financial, insurance and access barriers
  • Health literacy and communication approaches
  • Recognizing when to escalate a concern on a patient's behalf

Domain 5: Survivorship/End of Life (13%)

Often underestimated by navigators who work mainly in active treatment. This domain covers both ends of the later cancer journey.

  • Survivorship care planning and long-term follow-up needs
  • Palliative care and hospice navigation
  • Supporting patients and families through transitions in goals of care

Domain 4: Psychosocial Support Services/Assessment (10%)

Covers identifying emotional, social and practical needs and connecting patients to services.

  • Distress screening and what follows a positive screen
  • Matching patients to counseling, social work and community resources

The remaining domains are smaller but not skippable. Community Outreach/Prevention (9%) looks outward to screening, education and underserved populations. Professional Roles and Responsibilities (8%) addresses scope, ethics and the boundaries of navigation. Quality and Performance Improvement (7%) asks you to think about measuring and improving navigation outcomes. Operations Management (5%) is the smallest slice and deals with program-level functioning. A fuller walkthrough lives in ONN-CG Exam Domains: Complete Guide to All 8 Content Areas.

A naming wrinkle to know about: The issuer's 2024 preparation guide labels Domain 4 as "Psychosocial Distress Services/Assessment," while the live blueprint and the 2024 candidate handbook use "Psychosocial Support Services/Assessment." Both versions carry a 10% weight, so you are studying the same content either way. If you see both names in study materials, that is why.

Who Can Apply

The eligibility bar is higher than many certifications because it is built around real navigation practice. According to the issuer, applicants must have:

  • 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 no more than five of those from Tumor Board attendance.
  • A curriculum vitae, a current employer job description and an employer-signed reference.

A BSN is not required. This is a meaningful point for experienced nurses who built their careers on an associate degree or diploma pathway and have been wondering whether they are locked out. They are not, provided the experience, licensure and documentation requirements are met. Step-by-step qualification details are in ONN-CG Requirements: Eligibility, Prerequisites & How to Qualify.

Key Takeaway

Start gathering documents early. The employer-signed reference and an up-to-date job description that clearly shows navigation duties are the items most likely to take time, because they depend on other people. Make sure your job description reflects the navigation work you actually do.

Fees, Deadlines and Results Timing

Initial exam fee

The initial fee is USD 150 for AONN+ National Members and USD 300 for non-members. One detail trips people up: membership in a Local Navigator Network alone does not qualify you for the discounted fee. You need the AONN+ national membership. Given the gap between the two prices, comparing the cost of joining against the savings is worth doing before you apply. The full breakdown is in ONN-CG Certification Cost: Complete Pricing Breakdown.

Application timing

The candidate handbook requires that you apply at least 30 days before an approved examination date, and individual sessions can carry their own deadlines on top of that. Check the session-specific deadline rather than relying on the 30-day rule alone.

Scheduling caveat (checked October 15, 2026): The issuer's "Apply Here" page still displayed November 2025 sessions and an October 10, 2025 deadline, which is out of date. A newer official 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, with an October 1, 2026 application deadline and no onsite registration. That deadline had already passed when this was checked, so that session should not be treated as open for new applications. Confirm current availability directly with the issuer, and see ONN-CG Exam Dates: Testing Windows, Deadlines & Scheduling for updates.

Results and retakes

The handbook allows up to 45 business days for results, while the 2026 conference announcement describes six weeks for that particular session. Plan on a wait of several weeks rather than an instant score report. Candidates who are unsuccessful must wait at least six months before retesting and pay USD 45 for the next retest.

A numerical passing threshold and a published pass rate were not verified in the sources reviewed, so no figures are asserted here. For the current state of what is and is not publicly known, see ONN-CG Passing Score and ONN-CG Pass Rate: What the Data Shows.

Certification Term and Renewal

Once earned, the 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, a current job description and payment.

There is an unresolved discrepancy you should know about before budgeting. The dedicated live renewal page specifies a USD 150 renewal fee and a maximum of five Tumor Board CEs. The linked 2024 handbook, however, specifies USD 150 for members and USD 300 for non-members and a ten-CE Tumor Board cap. The live page is reasonable for provisional planning, but obtain confirmation from the issuer before relying on either the renewal fee or the Tumor Board allowance.

Key Takeaway

Treat CE collection as a continuous habit from day one of your three-year term. Keep certificates organized, and favor sources other than Tumor Board attendance for the bulk of your 45 credits so a cap change in either direction does not leave you short.

Who Values the Credential

Demand for ONN-CG tends to come from organizations that employ dedicated oncology navigators and want a standardized marker of competence:

  • Hospital cancer programs and comprehensive cancer centers, where navigators anchor multidisciplinary care.
  • Community oncology practices that rely on navigators to keep patients connected across settings.
  • Health systems building or expanding navigation programs, which often look for certified staff to lead them.
  • Programs seeking accreditation or quality recognition that emphasize patient navigation as a standard of care.

Because the credential requires three years of direct navigation experience, it signals seasoned practice rather than entry-level interest. Whether it translates into a raise or promotion varies by employer, so avoid assuming a specific figure. Explore the career side in ONN-CG Jobs, the earnings discussion in ONN-CG Salary Guide, and the value question in Is the ONN-CG Certification Worth It?.

Sequencing Your Preparation Around the Blueprint

You do not need an elaborate system, just a plan that lets the domain weights drive your calendar. Here is one way to allocate an eight-week runway, with the reasoning attached to each block.

Weeks 1-2

Coordination of Care/Care Transitions (27%)

  • Start here because it carries the most points and its concepts reinforce the other domains.
  • Work through referral tracking, handoffs and barrier identification scenarios.
Weeks 3-4

Patient Advocacy/Empowerment (21%) and Psychosocial Support (10%)

  • Pair these because they share patient-communication and resource-linking themes.
  • Practice distinguishing what a navigator does from what falls to social work or clinicians.
Weeks 5-6

Survivorship/End of Life (13%) and Community Outreach/Prevention (9%)

  • Give extra time if your daily work sits in active treatment, since these areas may be less familiar.
Week 7

Professional Roles, Quality and Operations (20% combined)

  • Three smaller domains grouped into one week; focus on scope, ethics and measurement vocabulary.
Week 8

Timed, closed-book practice

  • Simulate the three-hour, 120-question format with no breaks and no references, then review misses by domain.
