Private Pilot Knowledge Test: Format and Passing Score
✓ Reviewed against current FAA sources on October 5, 2026
In this guide
In short
The private pilot knowledge test is sixty multiple-choice questions with three options each, in two hours. There is no penalty for a wrong answer beyond its being wrong, so answer every question.
The private pilot written is a single sitting that most candidates overprepare for in the wrong places and underprepare for in the right ones. Here is what the test actually is, what it takes to be allowed to take it and where the questions come from.
The test at a glance
| Item | Value |
|---|---|
| Test name | Private Pilot, Airplane |
| Test code | PAR |
| Questions | 60 |
| Time allowed | 2 hours |
| Passing score | 70 |
| Age | 17 to hold the certificate, 15 to sit the written. The FAA lists 15 in its testing matrix because the report expires in 24 calendar months and you must be 17 by then |
| Governing standard | FAA-S-ACS-6C |
| Testing supplement | FAA-CT-8080-2H |

Questions are multiple choice with three options, and there is no penalty for a wrong answer beyond its being wrong. Answer every question. Two hours for sixty questions is two minutes each, which is generous for recall questions and tight for the handful that require a wind triangle or a weight and balance computation.
Becoming eligible to take it
You cannot simply book the test. You must present authorization, which is either a graduation certificate from an FAA-certificated pilot school for the ground portion of its course, or a written statement or logbook endorsement from an authorized ground or flight instructor certifying that you have completed a ground training or home study course and are prepared.
The home study route is explicitly permitted. If you work through a self-study course you obtain the endorsement from an instructor who has reviewed your preparation. This is a common and legitimate path, not a formality, and instructors are accustomed to providing it.
You will also need a Federal Tracking Number. Establish one through IACRA at iacra.faa.gov before you register. The FTN is printed on your test report and links your record across every certificate and test you will ever hold.
Where the questions come from
The subject matter is drawn from the knowledge elements of the Airman Certification Standards, the PA codes in FAA-S-ACS-6C. Those elements span all twelve Areas of Operation but they are not evenly weighted. Area I, Preflight Preparation, carries the great majority of the knowledge codes, because that is where regulations, weather, airspace, performance, systems and human factors all live.
The practical consequence: study effort is best spent on regulations, weather, airspace and performance. The flight maneuvers carry knowledge codes too, but far fewer, because most of what the ACS requires there is skill rather than knowledge.
The FAA does not publish the live question bank. It publishes sample questions, which are useful for format but several years old, and it publishes the testing supplement, which contains the actual figures used in the test. No study product can reproduce the live bank, and any that claims to is describing something else.
Reading your test report
Pass or fail, you receive an Airman Knowledge Test Report. It gives your score and, for every question you missed, an ACS code identifying the knowledge element involved. Those codes are the most useful thing on the page: they tell you precisely what to restudy, and your practical test examiner is required to question you on every area you missed.
If you do not pass, you may retest once you hold an instructor endorsement certifying additional training in the areas you missed. There is no mandatory waiting period for the PAR test, which surprises people who have heard otherwise about other FAA tests.
One thing to know about timing
The knowledge test result is valid for 24 calendar months. You must pass the practical test within that window or take the written again. This is also what decides how early a young candidate may sit the written: Section 61.35 (opens in a new tab) sets no minimum age for the test itself, only that you meet the age for the certificate before the report expires. Since Section 61.103 (opens in a new tab) requires you to be 17 for a private pilot certificate in an airplane, a candidate who tests at 15 must pass the checkride before the report runs out at 17. Candidates who pass the written very early, while still accumulating flight hours, sometimes run the clock out. Plan the written so it lands with enough of the window left to finish your flight training comfortably.
Most candidates go on to an instrument rating next, where a different set of clocks applies. See instrument currency and the IPC.
