Part 107 Passing Score & Retakes
How Part 107 scoring works: 70% to pass (42 of 60 scored questions), what the Airman Knowledge Test Report shows, and the 14-day retest wait after a fail.
Quick answer: you need 70% correct to pass — that’s 42 of the 60 scored questions, meaning you can miss up to 18 and still pass. Here’s exactly how that number is built, and what happens on either side of it.
The numbers
The UAG knowledge test is 60 scored questions plus 5 unscored validation questions, in 120 minutes, with a 70% passing score (UAG_Information_Bulletin.pdf, p. 4, effective September 29, 2025).
- 70% of 60 = 42. You need 42 correct scored answers to pass.
- The 5 validation questions aren’t scored — the FAA uses them to test new questions before adding them to the scored pool. You can’t tell which questions are validation questions, so answer every question as if it counts.
- The 120-minute time limit covers all 65 questions, scored and unscored together.

What your test report shows
Immediately after the test, you receive a printed Airman Knowledge Test Report (AKTR) documenting your score (uas_acs.pdf, Appendix 3, p. A-5). If you fail, the AKTR lists the ACS knowledge codes (like UA.I.B.K10) for the task elements you were weak on — so you know exactly which areas to restudy, not just that you fell short.
A passing AKTR is valid for 24 calendar months when applying for your Remote Pilot Certificate (uas_acs.pdf, Appendix 3, p. A-5). For tests taken on or after January 13, 2020, you can reprint a lost AKTR from your account at faa.psiexams.com.
If you don’t pass
A failed attempt means a 14-day waiting period before you can retest — no instructor endorsement or other written authorization is required (UAG_Information_Bulletin.pdf, p. 4). You do need to bring the failed AKTR itself to the testing center when you retest; the proctor scans it to verify your retest authorization before you begin.
There’s no limit on how many times you can retest after the 14 days pass.
What we can’t tell you yet
The current test fee isn’t published in any FAA or PSI document we’ve sourced (docs/faa-facts.md, “Needs verification”). PSI sets it and it can change independently of the rules above — check faa.psiexams.com directly before you schedule or retest.
