Failed the Part 107 Test: Retake Waiting Period, FTN, and Next Steps
Failing the Part 107 knowledge test is a normal part of the process. The waiting period is short, your FAA Tracking Number stays valid, and the test report you receive tells you exactly where to focus. Here is the full sequence from the moment you see the score to the moment you walk into the testing center again.

After you fail, you must wait 14 calendar days before you may retest. This is a hard minimum; testing centers will not schedule you earlier. There is no maximum number of attempts and no escalating penalty for repeated failures. The 14-day window is long enough to do a meaningful review of the areas you missed without losing momentum.
You do not need a new FAA Tracking Number
Your FTN is a single identifier tied to you, not to a particular test attempt. It was required before your first attempt and remains valid for every retake. You use the same FTN to book the retest, to receive the new test report, and ultimately to apply for your certificate after passing. If you have lost it, you can retrieve it from your IACRA account at IACRA.
Read your Airman Knowledge Test Report (AKTR)
You receive your Airman Knowledge Test Report (AKTR) at the testing center when you finish. Keep it. It shows your score and lists the Airman Certification Standards (ACS) codes for the knowledge areas of the questions you answered incorrectly. It does not break your score down by percentage for each area. Look up each code in the ACS at Remote Pilot ACS (PDF): a code such as UA.II.B.K1 points to a specific topic (here, airspace), so the list tells you where you lost points. If most of the codes fall under one area, such as Airspace (UA.II), spend most of your review time there rather than spreading it evenly across every topic.
Study strategy for the retake
The test is 60 scored questions plus 5 unscored validation questions, in 120 minutes, with a 70% pass mark. That means you can miss at most 18 of the 60 scored questions. A practical approach: first, go through every question you answered wrong on your last attempt and understand why the correct answer is correct and why your answer was wrong. Second, work the FAA's own sample questions at FAA UAG sample questions (PDF) to calibrate your pace and question style. Third, use the Airman Certification Standards at Remote Pilot ACS (PDF) as a checklist to confirm you can explain each objective in your own words. Fourth, if Airspace was your weak area, practise reading the sectional chart and the UAS Facility Map until you can identify Class B, C, D, and E surface areas, read the altitude blocks, and determine whether a location requires LAANC authorisation. The testing supplement at FAA-CT-8080-2H testing supplement (PDF) contains the chart and figure examples that appear on the actual test.
Rebooking the test
Once the 14-day window has passed, you book a new appointment at an FAA-approved testing centre. Find one and schedule through FAA: Knowledge Testing Centers. You will need your FTN, a valid government-issued photo ID, and the test fee (confirm the current amount with the centre or the testing vendor, as it can change). Walk in, present your ID, and the proctor will verify your identity and your FTN in the system. The test is delivered on a computer at the centre. You will see your score immediately upon completion. If you pass, you apply for your remote pilot certificate in IACRA. After the TSA security check, the FAA issues a temporary remote pilot certificate, valid for up to 120 calendar days, while the permanent one is produced.
What to do if you failed by a narrow margin
If you scored 65% or 68%, you were close. In that case, the highest-yield action is to review the topics behind the ACS codes on your AKTR and to work 10–15 practice questions in those areas before retaking. Use the full 14-day wait to study rather than cramming the day before. If you scored below 60%, treat it as a signal that your initial study was incomplete. Go back to the full ACS at Remote Pilot ACS (PDF) and work through it systematically rather than drilling random questions.
Common questions
How many times can I fail the Part 107 test?
There is no limit on the number of attempts. Each failure starts a new 14-calendar-day waiting period, and you use the same FTN each time. The practical cost is your time and the test fee for each attempt.
Do I have to retake the entire 60-question test, or just the questions I got wrong?
You retake the entire test. There is no partial retest or section-by-section retake. You get a fresh set of 60 scored questions drawn from the same blueprint, so the specific questions will differ from your first attempt.
Can I retake the test on the same day I failed?
No. The 14-calendar-day minimum applies regardless of how close you were to passing. Plan your study around that window.
Do I need to retake any training or get a new endorsement before retaking?
No. The Part 107 knowledge test has no prerequisite training or endorsement requirement. You need a valid FTN, a photo ID, and the 14-day wait to have elapsed. You may study on your own, with a course, or with a flight instructor, but none of that is a condition of being allowed to retest.
What happens to my score from the failed attempt?
The FAA keeps a record of each attempt, but a failed attempt does not count against you. Once you pass, it is the passing test that supports your certificate application, and there is nothing further to do about the earlier failure.
