How the Part 107 test is scored
The scoring is simple and published, which puts it ahead of most exams people prepare for. What surprises candidates is not the score — it is the report: you walk out with a list of codes rather than a list of questions, and nobody explains what to do with it.
The numbers, all from one appendix
| What the FAA publishes | Figure |
|---|---|
| Questions | 60 |
| Time limit | 120 minutes (2 minutes a question) |
| Passing score | 70% |
| Marks that represents | 42 of 60 |
| Minimum age to sit the test | 14 |
| Minimum age to hold the certificate | 16 |
| Wait after a failure | 14 calendar days |
| Validity of a passing test report | 24 calendar months |
Appendix 1 and Appendix 3 of FAA-S-ACS-10B, read 27 August 2026, with the eligibility age from 14 CFR § 107.61(a) and the retest interval from § 107.71.
The two ages are different, and both are right
You must be 14 to take the knowledge test and 16 to hold the certificate. A 14-year-old can sit and pass the UAG and then wait, because a passing test report is valid for 24 calendar months.
Every prep site checked while building this one printed a single “age requirement”, which means each of them is wrong about one of the two steps. It is a small thing, and it is a good test of whether a source read the regulation or copied another site.
What the test report actually gives you
Immediately after the test you are handed an Airman Knowledge Test Report showing your score. It does not list the questions you got wrong — the item bank is confidential and printing them would publish it.
What it lists instead is ACS codes: one for each knowledge element the test found you deficient in, in the form UA.I.B.K21b. That code decomposes into the area of operation, the task and the element, and looking it up in the ACS gives you the sentence describing exactly what you did not know.
- UA — the Unmanned Aircraft ACS
- I — the Area of Operation, here Regulations
- B — the Task within it, here Operating Rules
- K21b — the knowledge element, here “Altitude limitations”
How the sixty questions are distributed
The FAA publishes a percentage band for each area of operation, which is unusual — most test publishers keep the breakdown to themselves. It means a mock test can be weighted the way the real one is rather than guessing.
| Area of operation | Share of the test | Questions in a 60-question test |
|---|---|---|
| I. Regulations | 15–25% | 12 in this site’s mock |
| II. Airspace Classification and Operating Requirements | 15–25% | 12 in this site’s mock |
| III. Weather | 11–16% | 8 in this site’s mock |
| IV. Loading and Performance | 7–11% | 5 in this site’s mock |
| V. Operations | 35–45% | 23 in this site’s mock |
Bands from Appendix 1 of FAA-S-ACS-10B. The right-hand column is how this site deals a full-length mock; every figure sits inside its published band, and the build fails if one drifts outside.
What nobody can tell you
There is no published pass rate for the UAG, and this site does not estimate one. There is also no “score you need” beyond 70% — the certificate is pass or fail and the number does not follow you anywhere.
What does follow you is the 24-month validity of the report. Pass, then apply through IACRA within that window, and the number on the report never matters again.

Take a practice testFrequently asked
- What score do you need to pass the Part 107 test?
- 70%. With 60 questions that is 42 correct answers, and the ACS states the passing score directly in Appendix 1.
- How long is the Part 107 knowledge test?
- 120 minutes for 60 questions — two minutes a question. The ACS describes the items as objective, multiple choice, with a single correct response, and each question independent of the others.
- What happens if I fail?
- § 107.71 requires a wait of 14 calendar days before retaking the test. No instructor endorsement or written authorization is required to retest, and you submit the failing test report to the testing centre before retesting.
- How long is a passing test report good for?
- 24 calendar months, per Appendix 3 of the ACS. That is the window in which you must apply for the certificate.
- What are the ACS codes on my test report?
- They identify the knowledge elements you answered incorrectly, not the questions. Each one resolves to a sentence in the Airman Certification Standards describing what that element covers — which is what tells you where to study.
