How Many Times Can You Retake the Part 107 Test?
There is no limit on retakes for the Part 107 knowledge test. You wait 14 calendar days between attempts and pay the $175 fee each time. What the score report tells you, how long to actually wait before booking again, and what to do in between.
There is no limit on how many times you can retake the Part 107 knowledge test. You wait 14 calendar days between attempts and pay the $175 testing fee each time.
The 14 day rule comes from 14 CFR 107.71, which applies to any applicant who fails any FAA knowledge test. The failed attempt does not appear on your eventual Remote Pilot Certificate, and the FAA does not share fail history with employers or state agencies.
What does it cost across attempts?
| Attempts to pass | Total fees paid | Soonest you could be certified |
|---|---|---|
| 1 | $175 | Same week if IACRA is processed quickly |
| 2 | $350 | 14 days plus IACRA processing |
| 3 | $525 | 28 days plus IACRA processing |
| 4 | $700 | 42 days plus IACRA processing |
What does the score report tell me?
When you fail, PSI prints an Airman Knowledge Test Report showing your numeric score, a fail verdict, and a list of Airman Certification Standards (ACS) codes for the topic areas where you missed questions. It does not list the specific questions you missed or the answers you gave.
Treat the ACS codes as your study map. If most of your codes cluster under Airspace Classification, that is the domain to drill before booking again.
The codes are short strings like UA.I.B.K1, where the letters trace back to sections of the FAA Airman Certification Standards document.
Keep the printed report. You will need the exam ID from a passing score report later to complete FAA Form 8710-13 in IACRA.
How long should I wait before retaking?
Fourteen days is the legal minimum, not a recommendation. People who fail by a small margin (around 65 to 69 percent) usually do better with two to three more weeks of focused drilling on their missed ACS codes.
People who fail by a wide margin almost always do better restarting with a structured course, which typically means four to six more weeks.
The retake fee is $175 either way, so spending two extra weeks reading and drilling costs nothing and substantially improves the odds you will not pay $175 a third time.
What should I do between attempts?
The highest value use of the wait period is pulling the ACS codes off your score report and drilling questions in those specific domains until you are scoring 85 percent or better on practice runs.
