- The exam is 120 multiple-choice questions in three hours, closed-book, per the 2024 Candidate Handbook.
- Knowledge for Practice (24%) and Patient Care (20%) together account for 44% of the blueprint.
- Exam fee is US$150 for national AONN+ members and US$300 for nonmembers; local-network membership alone does not qualify.
- Eligibility requires at least one year or 2,000 hours of direct navigation experience plus employer-signed documentation.
What This Credential Is (and Who Issues It)
OPN-CG stands for Oncology Patient Navigator-Certified Generalist. It is issued by the AONN Foundation for Learning, Inc. (AONN+ FFL), the certification arm connected to the Academy of Oncology Nurse & Patient Navigators. The "Generalist" designation signals that the exam tests broad, practice-wide navigation competence rather than a single tumor type or a clinical specialty.
Because several unrelated credentials share similar abbreviations, always confirm that any study material you use is built for the AONN+ FFL exam. If you are new to the credential itself, the explainers on what OPN-CG is and what OPN-CG stands for cover the basics before you dive into this review sheet.
Exam Format at a Glance
| Item | What the Handbook Specifies |
|---|---|
| Question count | 120 multiple-choice questions |
| Time allowed | Three hours |
| Language | English |
| Reference materials | Closed-book |
| Delivery (per 2024 handbook) | Paper-and-pencil, administered through AONN+ FFL |
| Retake rule | Six-month wait and US$45 |
| Certification period | Three years |
Three hours for 120 questions works out to a pace of roughly 90 seconds per item, which leaves a modest cushion for flagging and revisiting questions. Paper testing means you mark answers by hand, so practice working through full-length sets without digital aids such as highlighting tools or on-screen flagging.

The Eight Weighted Domains
The blueprint is organized into eight official domains. Memorize the weights; they should dictate how you allocate your limited study hours.
| Domain | Name | Weight |
|---|---|---|
| 1 | Patient Care | 20% |
| 2 | Knowledge for Practice | 24% |
| 3 | Practice-Based Learning and Improvement | 10% |
| 4 | Interpersonal and Communication Skills | 14% |
| 5 | Professionalism | 14% |
| 6 | Systems-Based Practice | 3% |
| 7 | Interprofessional Collaboration | 8% |
| 8 | Personal and Professional Development | 7% |
The weights sum to 100%. Three observations help with prioritization:
- Two domains carry 44%. Knowledge for Practice and Patient Care are the heart of the exam.
- Communication and Professionalism tie at 14% each. Together they equal 28%, which is more than many candidates budget time for.
- Systems-Based Practice is only 3%. It is the smallest domain, so avoid over-investing there at the expense of heavier areas.
For a deeper walk-through of each area, read the complete guide to all 8 OPN-CG content areas.
High-Yield Content by Domain
The domain names borrow language from competency-based professional frameworks, so questions tend to be scenario-driven: you are placed in a navigator's role and asked for the best next action. Use the following as a checklist of themes to master. Treat these as study prompts that reflect what the domain titles imply, and confirm exact content coverage in the official preparation guide.
Domain 2: Knowledge for Practice (24%)
The largest domain tests whether you have the foundational oncology and navigation knowledge to guide patients safely.
- The cancer care continuum: prevention, screening, diagnosis, treatment, survivorship, and end-of-life care
- Core treatment modalities and what each means for a patient's schedule, side effects, and logistics
- Terminology you must be fluent in so you can explain next steps without drifting into clinical decision-making
- The boundaries of the navigator role versus nursing, social work, and physician responsibilities
Domain 1: Patient Care (20%)
This domain centers on what you actually do for patients day to day.
- Identifying and addressing barriers to care, whether financial, transportation, language, health literacy, or emotional
- Coordinating appointments, diagnostics, and treatment so nothing falls through the cracks
- Screening for distress and psychosocial needs and routing patients to the right resources
- Supporting patients through transitions, including from active treatment to survivorship
Domain 4: Interpersonal and Communication Skills (14%)
Expect situational items about difficult conversations and patient-centered communication.
- Active listening, plain-language explanation, and teach-back style confirmation of understanding
- Culturally responsive communication and working with interpreters
- Communicating with distressed, angry, or overwhelmed patients and family members
Domain 5: Professionalism (14%)
Ethics and boundaries are the recurring theme.
- Confidentiality and privacy obligations when handling patient information
- Maintaining professional boundaries and recognizing conflicts of interest
- Accountability, honesty, and knowing when to escalate or refer
- Respect for patient autonomy and diverse values
Domains 3, 6, 7, and 8 (10%, 3%, 8%, 7%)
These four smaller domains add up to 28% of the exam, so they are not safe to skip.
- Practice-Based Learning and Improvement: using feedback, tracking outcomes, and applying quality-improvement thinking to navigation work
- Systems-Based Practice: understanding how healthcare systems, payers, and community resources shape patient access
- Interprofessional Collaboration: working effectively within the multidisciplinary oncology team
- Personal and Professional Development: self-assessment, lifelong learning, and managing your own well-being in a demanding role
Key Takeaway
Do not read the small domains as optional. At 28% combined, a weak showing across Practice-Based Learning, Systems-Based Practice, Interprofessional Collaboration, and Personal and Professional Development can cost you as much as missing most of Patient Care.
Fees, Retakes, and Renewal Numbers
The fee structure rewards national membership, but only at the right level. Here is the verified summary:
| Item | Amount | Notes |
|---|---|---|
| Exam fee, national AONN+ member | US$150 | Member rate requires national membership |
| Exam fee, nonmember | US$300 | Local-network membership alone does not qualify for the member rate |
| Retake | US$45 | Six-month waiting period applies |
| Renewal | US$150 | Live renewal page lists this for both members and nonmembers |
Because the member discount is US$150 off the exam fee, check whether national membership makes sense for you before you register. The OPN-CG certification cost breakdown lays out the full spending picture, and the ROI analysis helps you weigh it against career benefits.
Renewal Mechanics
- Certification is valid for three years.
- Renewal requires 24 continuing-education credits within 36 months.
- You must also submit supporting employment documentation.
Start logging CE credits early in the cycle rather than scrambling in year three, and keep certificates and employer paperwork in one folder.
Eligibility and Documentation Checklist
You must be in current patient-navigation practice and have at least one year or 2,000 hours of direct navigation experience. That experience must be supported with documents. Assemble these before you apply:
- Curriculum vitae reflecting your navigation work
- Employer job description showing that navigation is a real part of your role
- Signed employer letter verifying your experience
Most applicant delays come from the employer letter, so request it early and make sure the signer understands what it needs to confirm. The full eligibility discussion is in the OPN-CG requirements guide, and scheduling windows are covered in the OPN-CG exam dates overview.
Where Certified Navigators Work
Oncology patient navigators are employed wherever cancer care is delivered or coordinated. Typical settings include:
- Hospital-based cancer centers and comprehensive cancer programs
- Community oncology practices and infusion centers
- Academic medical centers and research-affiliated programs
- Nonprofit and community-based cancer support organizations
- Health systems running screening and early-detection outreach
Job titles vary, and navigators come from nursing, social work, community health, and other backgrounds. That is one reason the exam's Generalist framing matters: it measures navigation competency regardless of your prior discipline. For a look at the market, see the OPN-CG jobs overview, and for compensation context without invented figures, the OPN-CG salary guide.
Sequencing Your Study by Domain
You do not need an elaborate system. What matters is sequencing the heavy-weight domains first and using the lighter ones for reinforcement. An example plan built around the blueprint:
Knowledge for Practice (24%)
- Review the cancer care continuum and treatment modality basics
- Build a one-page glossary of terms you must explain in plain language
- Mark the navigator-versus-clinician scope boundaries
Patient Care (20%)
- Work through barrier-identification and care-coordination scenarios
- Practice distress-screening and referral logic
Communication and Professionalism (14% each)
- Drill ethics, confidentiality, and boundary scenarios
- Review teach-back and culturally responsive communication approaches
Smaller Domains (28% combined)
- Cover Practice-Based Learning, Systems-Based Practice, Interprofessional Collaboration, and Personal and Professional Development
- Take a full 120-question timed set on paper
Weak-Spot Repair
- Revisit every domain where you missed items
- Do a final timed run-through under three-hour conditions
Adjust the length to your experience; a navigator with years in the field may compress this, while someone near the one-year minimum may want longer. For a fuller methodology, the OPN-CG study guide goes deeper, and you can test yourself against exam-style items on the main practice test site.
Key Takeaway
Practice on paper at least once. A closed-book, paper-and-pencil, three-hour sitting is a different physical experience from clicking through online questions, and your pacing should be rehearsed under realistic conditions.
Frequently Asked Questions
The 2024 Candidate Handbook specifies 120 multiple-choice questions with a three-hour time limit. The exam is in English and closed-book. Confirm the delivery format in your exam authorization, since public FAQ wording on paper versus computer has not been fully reconciled.
