FAA Private Pilot Knowledge Test: How to Register, Prepare and Pass (2026)
4 January 2023 | Updated on October 16, 2026
The FAA Private Pilot knowledge test (often called the “written”) is the first official exam on your way to a private pilot certificate. It is a computer-based multiple-choice test that you take at a PSI testing center. With good preparation it is very doable: in 2025, almost 9 out of 10 candidates passed.
This guide explains what is on the test, what you need before you can book it, how to register, what to bring, and how to prepare. Everything was checked against the FAA’s Airman Knowledge Testing Matrix and the PSI candidate information in October 2026.

What’s on the private pilot knowledge test?
The questions are based on the Private Pilot Airplane Airman Certification Standards (ACS), the same document your examiner uses during the checkride. The test covers the theory behind everything you do as a private pilot:
- Federal Aviation Regulations and pilot privileges and limitations
- Aerodynamics, aircraft systems and flight instruments
- Airspace, sectional charts and airport operations
- Weather theory, weather reports and forecasts (METARs, TAFs and charts)
- Navigation and cross-country flight planning
- Aircraft performance and weight and balance
- Aeromedical factors and aeronautical decision-making
Since 2026, the FAA is replacing many of the figures from the printed testing supplement with images embedded directly in the questions. The FAA updates its question pool every quarter, so make sure your study material is current.
Before you can book: 3 things you need
1. An FAA Tracking Number (FTN)
Create a free account as an applicant on IACRA, the FAA’s online application system. You will receive an FTN, which you will use for every knowledge test and checkride in your flying career. Do this before you book the test.
2. An endorsement
You need an endorsement from an authorized flight or ground instructor stating that you completed a ground training or home-study course and are prepared for the test. Graduates of a Part 141 flight school can use their graduation certificate instead.
The easiest route for most students is an online ground school: the good ones provide this endorsement when you finish the course. Rod Machado’s course, for example, issues a graduation certificate that serves as your test endorsement.
After completing Rod Machado’s ground school course, you’re issued a certificate to apply for the FAA knowledge exam.

3. A valid photo ID
Your ID must be valid and current and show your photo, date of birth, signature and physical residential address (a PO box is not accepted). A driver’s license or passport usually works. If you are under 18 and don’t have an ID, a parent or guardian can come along to vouch for you. Check the FAA’s Airman Knowledge Testing Matrix for all accepted forms of ID.
How to register for the test
- Get your FTN in IACRA and your endorsement from your instructor or ground school.
- Go to faa.psiexams.com, create an account and choose the Private Pilot Airplane (PAR) test.
- Pick a testing center and a time slot. Online booking is available around the clock.
- Pay the test fee (about $175).
You can cancel or reschedule up to 24 hours before your appointment. If you miss your appointment, you may lose the fee. The test is taken in person at a testing center; we know of no option to take it online from home.
What to bring on test day
- Your photo ID
- Your endorsement (or graduation certificate)
- A plotter and a flight computer (a mechanical E6-B or an electronic flight computer)
- A basic calculator, if you want one
The testing center provides scratch paper, and the testing supplement with charts and figures if your test still uses it. Phones, smartwatches and your own notes stay in a locker. Have a good breakfast, and arrive early so you are not stressed before you start.
How to prepare
- Finish a complete ground school first. Don’t start with question banks. Understand the theory first, and the questions become much easier.
- Then drill practice questions. Most courses include hundreds of FAA-style questions. Keep going until you consistently score well above 70% on full practice exams.
- Focus on your weak areas. Weather, airspace and cross-country planning trip up most students. Review those chapters again instead of just memorizing answers.
- Use the free FAA material. The Pilot’s Handbook of Aeronautical Knowledge (PHAK), the Airplane Flying Handbook and the Private Pilot ACS are free on faa.gov, and PSI offers a free sample test.
- Take the test while it’s fresh. Book it soon after you finish your course, ideally early in your flight training.
In the PPL training diary on this site, the student pilot worked through almost 1,000 database questions and a progress check before the theory exam, and found the real exam easier than the question database. That is the goal: if you are comfortable with your practice questions, test day holds few surprises.

Tips for the test itself
- Write down your memory aids first. Rod Machado recommends spending the first few minutes noting everything you memorized on your scratch paper: the airspace diagram, the VOR orientation trick, “high to low, look out below”. You can then use them for the rest of the test.
- Answer the easy questions first. Skip anything you are unsure about and come back to it. It builds confidence and saves time.
- Save the calculations for last. Cross-country, performance and weight and balance questions take the longest.
- Read every question twice. Many wrong answers look attractive because they answer a slightly different question.
- Eliminate wrong answers. With three options, ruling out one already gives you a 50/50 chance.
- Check the chart scale. Make sure the scale on your plotter matches the chart in the question before you measure distances.
- Only change an answer if you are sure. Your first instinct is often right.

After the test: your results
You receive your Airman Knowledge Test Report (AKTR) right after the test. It shows your score and the ACS codes of the subject areas where you missed questions. Keep the original in a safe place. You need it for your checkride, and your examiner will review those weak areas with you during the oral exam. If you lose it, you can print a duplicate through PSI for tests taken since 2020.
After passing, you have 24 calendar months to pass your checkride. That sounds like a lot, but flight training can take longer than planned, so don’t take the test too early.
What if you fail?
It happens, and it’s not the end of the world. To retake the test, you need your failed test report and a new endorsement from an instructor who gave you additional training in the areas you missed. The instructor can sign the instructor’s statement section of your AKTR. There is no mandatory waiting period for the private pilot test. Use the ACS codes on your report to see exactly what to review.
