The FAA knowledge test — pilots still call it the written — is a proctored exam on the knowledge required for a certificate or rating. Private, instrument, commercial, and flight instructor applicants on a typical Part 61 path all sit one (CFI applicants sit two: Fundamentals of Instruction and the Flight Instructor Airplane test). Passing it does not make you a pilot. Failing it does not end the project. It is one required step, and it is easier to treat it that way.

Under 14 CFR 61.35, you generally may not sit for that test until an authorized instructor endorses that you completed the appropriate ground training and are prepared to take it. Part 141 graduates and a few other paths use different paperwork. For most independent students, the endorsement is the gate. It is a professional judgment about preparation. It is not a forecast of the number you will see on the printout.

That distinction is the whole point of this page. An endorsement authorizes the testing center to start the exam. It does not replace the time you will spend with the handbooks, a practice bank, and an instructor who will answer the questions the bank cannot.

FAA knowledge tests are given at FAA-approved testing centers. You bring government photo ID and your authorization — typically the instructor endorsement and the Federal Tracking Number (FTN) you create in IACRA. The exam is multiple choice. The published passing standard is 70 percent. When you finish, you receive an airman knowledge test report with your score and the subject codes for the items you missed.

Keep the report. Before a practical test, your instructor is expected to review those missed areas with you. The codes are a study list for the oral, not a grade to hide in a drawer.

For most certificates and ratings, a passing knowledge-test result is valid for 24 calendar months when you present it for the practical test (14 CFR 61.39). If that window closes first, you take the knowledge test again. That is a calendar rule, not a comment on your flying.

The Airman Certification Standards describe knowledge, risk management, and skill. The written samples knowledge and some risk management. The practical test samples all three. Students who only memorize question stems often reach the testing center and then stall when a designated examiner asks them to explain the answer. The more durable habit is to study each ACS topic as material you will later fly and discuss.

A method that works whether or not you buy a course:

1. Download the current ACS for the certificate or rating you want.

2. Read the FAA handbook chapters that map to those topics — the Pilot’s Handbook of Aeronautical Knowledge and the Airplane Flying Handbook for private; add the Instrument Flying Handbook for instrument; add the Aviation Instructor’s Handbook for CFI.

3. After you read a topic, work practice questions. Write down every miss and the reference that explains it.

4. Take the questions you cannot settle to an instructor.

5. When the material is familiar — not just the stems — ask for the endorsement.

Video can show a system or a procedure clearly. It is support for a syllabus. It is not a syllabus by itself.

If you want that path in one place, Veni, Vidi, Volavi is an online ground school designed by pilots for pilots. When you finish the course work, an authorized instructor can review it for the knowledge-test endorsement. Use it when the training is actually done.
