ONN-CG Exam Dates 2026: Testing Windows, Deadlines & Scheduling

The 2026 Scheduling Picture at a Glance

The Oncology Nurse Navigator-Certified Generalist (ONN-CG) credential is administered by the AONN+ Foundation for Learning (AONN+ FFL). Unlike credentials delivered year-round at commercial testing centers, this exam is tied to specific in-person sessions. That changes how you plan: instead of picking any open appointment, you plan around a short list of official sessions and application cutoffs.

As of the most recent check of official sources (October 15, 2026), the clearest 2026 session information comes from the AONN+ Annual Conference announcement. The table below summarizes what is confirmed and what is not.

The November 11, 2026 Session in Grapevine

The 2026 AONN+ Annual Conference announcement lists ONN-CG testing on Wednesday-morning scheduling, 8:30-11:30 a.m., at the Gaylord Texan Resort & Convention Center in Grapevine, Texas. That three-hour window matches the exam's three hours of testing time, which means there is no cushion built into the session for late arrival.

What this means for travel and logistics

• Plan to be on site early. A paper-and-pencil exam with a fixed start time is not forgiving of delays. Arrive the evening before if you are traveling.
• Confirm your admission details with the issuer. The linked registration page returned no readable public content when checked, so no checkout details, room assignments or check-in instructions should be assumed.
• Budget separately for the conference. The exam fee (USD 150 for AONN+ National Members, USD 300 for non-members) is distinct from any conference registration or hotel costs. Our ONN-CG certification cost breakdown covers the pricing in detail.

Because the testing session is attached to a conference, you may also want to ask your employer whether conference attendance can be paired with your exam trip, particularly since your employer must sign your reference documentation anyway.

Why Some AONN+ Pages Still Show 2025 Dates

One of the most common sources of confusion for candidates is that the issuer's own pages do not all agree. The "Apply Here" page at aonnffl.org/apply still displayed November 2025 sessions and an October 10, 2025 deadline when checked. The newer Annual Conference announcement at aonnonline.org is the source that lists the November 11, 2026 session and the October 1, 2026 deadline.

This is not a criticism so much as a practical warning. Third-party sites, including ours, can only report what the official pages say on the day they were checked. Never book non-refundable travel on the strength of a single web page. A short email to the issuer asking for written confirmation of the session date, location and application deadline is cheap insurance.

How Application Deadlines Actually Work

There are two layers of timing to understand, and candidates sometimes mix them up.

1. The handbook rule. The ONN-CG Candidate Handbook requires that you apply at least 30 days before an approved examination date.
2. The session-specific deadline. Individual sessions can carry their own cutoffs. For the November 11, 2026 session, the announced deadline was October 1, 2026, which is roughly 41 days before the exam, a little earlier than the 30-day minimum.

The practical lesson: the 30-day handbook rule is a floor, not a target. Whichever date is earlier governs you. Build your plan around the session-specific deadline, and treat the handbook's 30 days as the absolute minimum if a session announcement is ever silent on its own cutoff.

What Test Day Looks Like: Format and Rules

Knowing the format helps you judge how much preparation time a given session date really gives you.

• Delivery: in person, paper-and-pencil, English language.
• Length: 120 multiple-choice questions.
• Time: three hours of testing time, which averages out to about 90 seconds per question.
• Resources: closed-book.
• Breaks: none scheduled. Individual breaks are permitted, but the timer keeps running.

Paper-and-pencil delivery rewards a different habit than computer-based testing. You can mark up your booklet in whatever way the testing rules allow, skip and return, and you must manage your own pacing without an on-screen clock reminder in front of you. Practice with a wristwatch-style pacing plan, such as checking that you have finished roughly 40 questions per hour.

How the blueprint shapes your scheduling decision

The exam is built from eight weighted domains totaling 100%. Because two domains carry nearly half the weight, your readiness depends heavily on them:

The remaining weights are Community Outreach/Prevention (9%), Psychosocial Support Services/Assessment (10%), Survivorship/End of Life (13%), Professional Roles and Responsibilities (8%), Operations Management (5%), and Quality and Performance Improvement (7%). For a deeper walk-through of each area, see the complete guide to all 8 ONN-CG content areas.

Eligibility Paperwork You Need Before Booking

You cannot simply pick a session and show up. The application requires proof that you qualify, and gathering it takes longer than most candidates expect. The documented requirements are:

• An active RN license in good standing (a BSN is not required)
• Current employment in navigation and at least three years of direct navigation experience
• 15 navigation CEs in the preceding 12 months, with a maximum of five from Tumor Board attendance
• A CV
• Your current employer job description
• An employer-signed reference

The employer-signed reference is the item most likely to stall you, because it depends on someone else's calendar. Request it early. The 12-month CE window also matters for timing: CEs earned more than a year before your application do not count toward the 15, so check your dates before you assume you are covered. For the full qualification checklist, read the ONN-CG requirements guide.

Results Timing and Retest Windows

Your scheduling decision does not end on exam day. Two timing rules affect what happens next.

When to expect results

The handbook allows up to 45 business days for results. The 2026 conference announcement, however, gives six weeks for that specific session. If you need your credential for a job application, a promotion review or a contract renewal, plan around the longer handbook window rather than the shorter figure, and avoid scheduling anything that depends on having results in hand within six weeks.

If you do not pass

Unsuccessful candidates must wait at least six months before retesting, and the retest fee is USD 45. Because sessions are limited, the practical gap between attempts can be longer than six months. That makes a strong first attempt more valuable than it would be with on-demand scheduling. A numerical passing threshold and an official pass rate were not verified in the sources used for this article, so we do not assert either; see our pages on the ONN-CG passing score and the ONN-CG pass rate for how we handle that gap.

Planning Backward From a Test Date

Because the exam is tied to fixed sessions, the smartest approach is to work backward from the deadline, not the exam date. The following timeline is a planning model, not an official schedule. It assumes a roughly 14-week runway before the application cutoff and weights your time toward the blueprint.

Front-loading the two largest domains gives you the most return on your early weeks, and it leaves time to circle back to them in the final simulation phase. For a fuller plan, including resources and review methods, see the ONN-CG study guide. When you are ready to test yourself under realistic conditions, the ONN-CG practice tests let you rehearse the pacing that a three-hour, no-scheduled-break exam demands. If you are still sizing up the effort involved, how hard the ONN-CG exam really is is a useful companion read.

After You Pass: The Three-Year Clock

Certification lasts three years, so the date you test effectively sets your renewal calendar. Renewal requires 45 CEs over 36 months, continued RN good standing, an updated CV, a signed recommendation, your job description and payment.

There is an unresolved discrepancy worth knowing about now. The dedicated live renewal page specifies a USD 150 fee and a maximum of five Tumor Board CEs, while the linked 2024 handbook specifies USD 150 for members and USD 300 for non-members and a ten-CE Tumor Board cap. For provisional planning, use the live renewal page, but obtain issuer confirmation before relying on any renewal fee or Tumor Board allowance. Start logging CEs from the day you pass so the 45-credit target never becomes a scramble.
