- The CTO written test has no fixed national "testing windows" - it's scheduled individually with an FAA-designated CTO examiner.
- Passing score is 70%, there's no maximum testing time, and a passing result never expires.
- Failed attempts require a 30-day wait, or sooner with a signed 14 CFR 65.19 additional-instruction and readiness statement.
- Written-test applicants must show they'll reach age 18 within two years of applying - plan your timeline around that rule.
There Are No Fixed CTO Testing Windows in 2026
If you're used to certification exams that publish quarterly registration windows or annual testing blackout periods, the Control Tower Operator written knowledge test works differently. There is no published 2026 "testing season," no registration portal with a countdown clock, and no fixed cutoff dates comparable to what you'd find with many other credentials. The written test governed by 14 CFR 65.35 is administered by an FAA-designated CTO examiner, and scheduling happens on an individual, appointment basis rather than through a centralized calendar of open windows.
That structure matters for how you plan. Instead of asking "when does registration open," the better question is "when am I actually ready, and when can I get in front of an examiner." This guide walks through the realistic scheduling mechanics, the eligibility timing rules that do have hard deadlines, and how to sequence your preparation so you're not scrambling when a test slot becomes available.
How CTO Written Test Scheduling Actually Works
Because an FAA-designated CTO examiner administers the multiple-choice written test, your scheduling conversation starts with locating and coordinating with that examiner rather than a national testing network. This is a meaningful distinction from exams tied to large commercial test-center chains. Practical implications for 2026 planning:
- No maximum testing time is imposed, so your appointment slot should be planned around your own pacing, not a countdown clock.
- Passing score is 70%, and once you pass, that written-test result does not expire - there's no "retake before it lapses" pressure once you're through.
- Coordination with the examiner determines the actual date, so building in buffer time before any personal deadline (a hiring announcement, an application cycle) is wise.
Before locking in a date, most candidates benefit from working through a full CTO Study Guide 2026: How to Pass on Your First Attempt to confirm they're actually ready rather than testing prematurely just because a slot opened up.
Key Takeaway
Treat scheduling as a readiness-driven decision, not a calendar-driven one. Since there's no expiration on a passing result and no fixed window to catch, there's little upside to testing before you've covered all seven domains thoroughly.
Eligibility Timing: Age, Medical, and Application Deadlines
While there's no fixed testing window, there ARE hard timing rules baked into eligibility that function like deadlines. Get these wrong and your test date becomes irrelevant.
Age Timing Rule
Written-test applicants must demonstrate they will reach the certificate minimum age of 18 within two years of the written-test application. This is a forward-looking window, not a backward-looking one - you can apply to test before turning 18, but only within that two-year runway.
- Younger candidates should map their written-test date against this two-year rule before committing to a schedule
- Certificate issuance itself still requires actually being 18 at the time of certification
Medical Timing Rule
Certificate applicants must hold at least a second-class medical certificate issued within the preceding 12 months, alongside meeting English-language and good-character requirements - subject to the FAA and military exceptions found in 14 CFR 65.33(d).
- A medical certificate that's about to age past 12 months should be renewed before you finalize your certificate application timing
- This 12-month clock is separate from the written-test scheduling clock, so track them independently

2026 Calendar Considerations: JO 7110.65BB Change 3
One concrete date every 2026 candidate should mark: the online JO 7110.65BB includes Change 3, effective July 9, 2026. This procedural reference underpins several written-test topics tied to controller phraseology and operating procedures. If your test date falls close to that effective date, confirm which version of the procedural reference your preparation materials and your examiner are working from.
| Reference | Relevance to 2026 Test Dates |
|---|---|
| FAA February 2022 CTO study guide | Core content guide; use alongside current procedural references |
| JO 7110.65BB, Change 3 (effective July 9, 2026) | Confirm which edition applies if testing near this date |
| Written-test result | Does not expire once you pass - no re-testing deadline afterward |
| Certificate itself | Permanent; remains effective until surrendered, suspended, or revoked |
Aligning Domain Study With Your Scheduling Timeline
Since you control when you request a written-test appointment, use that flexibility to sequence preparation around the seven statutory knowledge subjects rather than cramming everything into a single push. A staged approach also makes it easier to identify weak domains before you commit to a date with your examiner.
Foundational Rules
- Domain 1: Flight rules under 14 CFR Part 91
- Domain 2: Airport traffic control procedures and 14 CFR Part 65, Subpart B
Traffic and Communications
- Domain 3: En route traffic control procedures
- Domain 4: Communications operating procedures
Assistance, Navigation, Weather
- Domain 5: Flight assistance service
- Domain 6: Air navigation and aids to air navigation
- Domain 7: Aviation weather
Integration and Scheduling
- Full-length practice sessions using original practice questions, not secured FAA test items
- Contact your examiner to lock in a written-test appointment
For a deeper breakdown of each subject area and how heavily it tends to be represented in question style, see the CTO Exam Domains 2026: Complete Guide to All 7 Content Areas. If you're still gauging how demanding this test really is relative to your background, How Hard Is the CTO Exam? Complete Difficulty Guide 2026 covers that in detail before you set a date.
Retesting After a Failed Attempt: Deadlines and Requirements
If your written-test scheduling doesn't go as planned, the retest rules are specific and worth knowing before test day, not after.
- Standard wait: Retesting after a failure is permitted after 30 days.
- Earlier retest option: You can test sooner than 30 days only with the signed additional-instruction and readiness statement required by 14 CFR 65.19, documenting that you received instruction and are prepared to retest.
Key Takeaway
Build the 30-day rule into your personal calendar the moment you schedule a first attempt. If a hiring deadline is close behind, the readiness-statement path under 14 CFR 65.19 is the only way to compress that timeline.
Because the written-test result itself never expires once you pass, there's no long-term penalty for taking extra weeks to prepare properly rather than rushing into a retest. For context on how many candidates need more than one attempt, see CTO Pass Rate 2026: What the Data Shows.
FAA Hiring Cycles and Why Timing Matters
The written knowledge test is one piece of a longer path toward operating as a certificated Control Tower Operator, which also involves facility-rating qualification and practical elements outside the scope of the written exam itself. Because hiring announcements and facility staffing needs can move on their own schedule, candidates often benefit from having their written-test result already in hand before an opportunity opens, rather than trying to schedule a written test reactively once a position is posted.

And if you're specifically researching where this credential leads on the job side, CTO Jobs covers that ground.
Day-of Test Logistics and Approved Aids
Once your appointment with the FAA-designated examiner is confirmed, a few logistical points are worth locking down in advance:
- Approved materials only: Only FAA-authorized test aids are permitted during the written test - confirm with your examiner exactly what's allowed before test day so nothing gets flagged at check-in.
- No time pressure, but plan anyway: There's no maximum testing time, but arriving with a plan for pacing through the multiple-choice format still helps you avoid second-guessing every question.
- Reference materials to study from beforehand: Use the FAA February 2022 CTO study guide together with current procedural references - not outdated versions - especially given the JO 7110.65BB Change 3 update landing mid-2026.
For a condensed, last-mile review before your scheduled appointment, many candidates keep the CTO Cheat Sheet 2026: One-Page Review of Must-Know Facts on hand alongside full-length practice sessions on the main practice test platform. Running timed, original practice questions on the practice test site in the days before your appointment is one of the most reliable ways to confirm you're actually ready rather than guessing.

Frequently Asked Questions
No. The written test is scheduled individually with an FAA-designated CTO examiner under FAA Order 8000.90C, Appendix C, rather than through fixed national testing windows.
No. Once you pass the written test, the result does not expire. However, operating privileges tied to the certificate still depend on ongoing currency requirements under 14 CFR 65.50.
Standard policy allows retesting after 30 days. You can retest sooner only with the signed additional-instruction and readiness statement required by 14 CFR 65.19.
Yes, if you can show you will reach the certificate minimum age of 18 within two years of your written-test application. Actual certificate issuance still requires being 18.
Confirm with your examiner whether your preparation materials and the online JO 7110.65BB reference reflect Change 3, which becomes effective on that date.
