Scheduling and Taking the Part 107 Knowledge Test
With an IACRA account and FTN in hand (Lesson D), the next step is scheduling and passing the Aeronautical Knowledge Test ? officially titled "Unmanned Aircraft General ? Small (UAG)." This lesson covers who administers the test, how to book it, exactly what to bring, what the test-day experience looks like, and the rules that apply if you don't pass on the first attempt.
Who administers the test
Knowledge tests under Part 107 are given "by persons and in the manner designated by the Administrator" ? in practice, the FAA designates PSI Services LLC as the authorized vendor that operates the nationwide network of proctored testing centers where the Part 107 Aeronautical Knowledge Test is delivered. You cannot walk into just any testing facility; it must be a PSI-authorized center offering the FAA "UAG" exam.
What the test covers and how it's structured
The Unmanned Aircraft General ? Small (UAG) exam is a proctored, multiple-choice knowledge test covering the areas of knowledge specified in 14 CFR 107.73 ? the same 13 knowledge areas this entire course is organized around, mapped to the ACS Areas of Operation I through V (see Lesson J for the full mapping). The FAA sets the minimum passing grade administratively rather than in the regulation text itself, and that passing score is 70%.
Expect a mix of straightforward regulatory-recall questions (e.g., citing a specific altitude or distance limit) and applied scenario questions that require reading a chart, graph, or weather report excerpt and reasoning through the correct answer ? this is why Modules 3, 4, 5, and 6 of this course emphasize practicing the underlying skill (chart reading, METAR decoding, performance-graph reading) rather than memorizing any one example.
What you must bring to the test center
Under 14 CFR 107.67(b), you must present identification containing a photograph, your signature, your date of birth (showing you meet the age requirement), and your permanent mailing address ? if that address is a P.O. box, you must also provide a current residential address. A government-issued photo ID such as a driver's license or passport satisfies this. You will also need your FTN from Lesson D to check in.
- No personal electronics in the testing room: Phones, smartwatches, and similar devices are typically not permitted at the workstation once testing begins.
- The Airman Knowledge Testing Supplement is provided at the center: Figures, charts, and legends referenced by test questions (sectional chart excerpts, load factor charts, and similar figures) are supplied to you at the testing center itself ? you are not expected to have memorized any specific figure from that document in advance. What matters is being able to read and interpret an unfamiliar chart or graph under time pressure, which is the skill this course builds throughout Modules 3 through 6.
- Basic on-screen tools are typically provided: Testing centers generally provide scratch materials and a basic calculator function as part of the testing software; personal calculators are not needed for the UAG exam's math (which is limited to straightforward chart-reading and simple arithmetic).
Fees and retesting after a failed attempt
PSI charges a fee for the Knowledge Test, set and periodically updated by the vendor ? always confirm current pricing directly through PSI's official test registration site before booking, rather than relying on a remembered number, since testing fees are adjusted from time to time.
If you do not pass on your first attempt, 14 CFR 107.71 requires a minimum 14-calendar-day wait before you can reapply and retake the test ? there is no way to retest sooner, even at a different testing center. Use that mandatory waiting period productively: Lesson F explains exactly how to read your test results and target your remaining study time at the specific ACS areas you missed.
Real-world scenario: preparing for test day
Amara has finished studying and books her UAG exam through PSI two weeks out, selecting a testing center near her home. The night before, she confirms she has a valid, unexpired driver's license with her current address (matching what she entered in IACRA) and her FTN written down. She arrives 30 minutes early as PSI recommends, checks in with her photo ID and FTN, stores her phone in the provided locker, and is seated at a workstation. The testing supplement with sectional chart excerpts and reference figures is already provided by the center ? she doesn't need to bring her own copy. Because she practiced reading unfamiliar charts throughout her studies rather than memorizing one figure, she's able to work through the chart-based questions confidently even though none of them match any example she studied exactly.

|---|---|---|---|
| Exam name/code | Unmanned Aircraft General ? Small (UAG) | Initial certification exam | FAA/PSI |
| Testing vendor | PSI Services LLC | Nationwide proctored testing centers | 14 CFR 107.67(a) |
| Question format | Multiple-choice | Covers 107.73 knowledge areas | 14 CFR 107.73 |
| Minimum passing grade | Set by the Administrator (70%) | Not a fixed number in the regulation text itself | 14 CFR 107.67(c) |
| Retest wait period | 14 calendar days minimum | No exceptions for different test centers | 14 CFR 107.71 |
| Required ID | Photo, signature, DOB, permanent mailing address | P.O. box address requires a current residential address too | 14 CFR 107.67(b) |
From booking to walking out of the test center
Have your FTN and a valid photo ID ready before you start scheduling.
Go to PSI's official test registration site
Search for the UAG exam specifically ? confirm it is the Part 107 Unmanned Aircraft General ? Small exam, not a different aviation knowledge test PSI also administers.
Enter your FTN and personal details, then select a testing center and time
Choose a center and appointment time that gives you enough runway to finish your studying ? most applicants find it easiest to book a specific date a week or two out as a study deadline to work toward.
Pay the testing fee and confirm your appointment
Save or print your confirmation, and double-check the exact address and check-in time for your chosen testing center.
Arrive early with your ID and FTN
Bring a valid, unexpired government-issued photo ID matching the name on your IACRA profile, along with your FTN.
Complete check-in and take the exam
Personal items are typically stored outside the testing room. The proctor seats you at a workstation; any reference figures the test needs are provided by the center as part of the Airman Knowledge Testing Supplement.
Receive your Airman Knowledge Test Report
Your score and pass/fail result are provided at the conclusion of the test. Keep this report ? you'll need information from it to complete Form 8710-13 in Lesson G, and Lesson F explains exactly how to read it.
| Mistake | Why it happens | Correct understanding | Regulation / source |
|---|---|---|---|
| "I need to memorize every figure in the Testing Supplement before test day." | Assuming the supplement is a study document rather than a test-day reference tool | The supplement is handed to you AT the test center; the goal is being able to read an unfamiliar chart quickly, not memorizing specific published figures. | FAA Testing Supplement policy |
| "If I fail, I can retest the next day at a different center." | Assuming the wait period is center-specific | The 14-calendar-day wait applies regardless of which testing center you use for the retest. | 14 CFR 107.71 |
| "Any photo ID, even if expired, will work." | Underestimating testing-center ID verification standards | ID must be valid/unexpired and contain a photo, signature, date of birth, and permanent mailing address. | 14 CFR 107.67(b) |
| "The passing score is written directly in 14 CFR Part 107." | Assuming every numeric requirement appears in the regulation text | 107.67(c) delegates the minimum passing grade to the Administrator; it is set administratively (70%), not stated as a number in the rule text. | 14 CFR 107.67(c) |
Do I need to bring my own copy of the Testing Supplement or sectional chart?
No. The Airman Knowledge Testing Supplement, including any sectional chart excerpts or reference figures a question needs, is provided to you at the testing center. You cannot bring your own annotated copy, and you don't need to ? the goal is testing your ability to read an unfamiliar figure, not recall a memorized one.
How long do I have to wait if I fail the test?
At least 14 calendar days from the date of the failed attempt, per 14 CFR 107.71. This applies no matter which PSI testing center you choose for the retest.
Will I find out my score immediately?
Yes. The Airman Knowledge Test Report, showing your score and pass/fail result, is provided at the conclusion of the test. Lesson F covers how to read it in full, including how missed questions map to specific ACS codes.
