Fundamentals of Instructing (FOI) knowledge test
The teaching test every new flight and ground instructor takes — learning theory, lesson planning, assessment and professionalism, in 50 three-choice questions.
About the exam
The Fundamentals of Instructing (FOI) test covers how people learn and how to teach them. It's taken by applicants for a flight instructor or ground instructor certificate — one FOI test serves every category — and it's built on Area of Operation I of the flight instructor ACS, drawn from the FAA's Aviation Instructor's Handbook. You're exempt if you already hold a flight or ground instructor certificate, hold a state teaching certificate for grade 7 or higher, or teach at an accredited college or university.
The test has 50 multiple-choice questions in 1 hour 30 minutes, each with three answer choices (A, B, C), and you need 70% to pass. It's taken on computer at a PSI test center, and there are no charts or figures. Since September 2024 you need an authorization to test: a graduation certificate from an FAA-certificated pilot school, or a logbook endorsement from an authorized instructor showing you completed a ground training or home-study course. You also need an FAA Tracking Number (FTN) from IACRA. A passing result stays valid for 24 calendar months for the practical test.
Our practice covers every Area I task with original questions mapped to the ACS, written in the Aviation Instructor's Handbook's exact vocabulary — laws of learning, levels of learning, defense mechanisms, the teaching process and the characteristics of a good test. Add flashcards for every key term and list, worked case walkthroughs of real teaching situations, illustrated guides to learning theory and lesson structure, and timed practice tests at the real length with a score.

Questions built on the official standard
Every question is tagged to an FOI task and ACS knowledge element — original three-choice questions in the FAA style, using the Aviation Instructor's Handbook's own terms and realistic teaching scenarios.
Hints that teach the concept
Reveal the learning principle or handbook definition behind the question when you're stuck. Every answer comes with the full rationale.
Adaptive practice
Questions steer toward your weakest areas, weighted like the real test, and get harder as you get stronger.
Timed practice tests
Full-length tests at the real pace — 50 questions in 1 hour 30 minutes — with a pacing indicator, full review and an estimated score against the 70% pass mark.
Flashcards, walkthroughs and guides
Flashcards for every term and list — laws of learning, levels of learning, defense mechanisms and test characteristics, worked case walkthroughs that reason through harder questions step by step, and interactive illustrated guides you explore hotspot by hotspot.
Progress in every area
Each area moves from Not started to Exam ready, so you know exactly what to study next.
Test at home or at a center
The FOI test is scheduled and taken through PSI, the FAA's knowledge-testing provider. Get your authorization and your IACRA FAA Tracking Number (FTN) first, then choose a PSI test center and time. Remote testing is not offered for FAA airman knowledge tests.
At a PSI test center
- Book through PSI's FAA scheduling site; the fee is paid to PSI, not the FAA — about $175 at PSI (confirm when you book).
- Bring a current government-issued photo ID that meets FAA identification rules, your FTN and your authorization.
- There's no testing supplement for FOI — every question is self-contained text.
- Phones, notes and bags are stored away for the whole test.
Before you book: authorization
- Since September 1, 2024, FOI requires authorization: a graduation certificate from an FAA-certificated pilot school, or a logbook endorsement from an authorized flight or ground instructor.
- The endorsement certifies you completed an applicable ground training or home-study course and are prepared for the test.
- You don't need FOI at all if you already hold a flight or ground instructor certificate, a state teaching certificate for grade 7 or higher, or teach at an accredited college or university.
- If you retake after a failure, bring the failed test report and an instructor's endorsement for the additional training you received.
Exam-day game plan
How to walk in ready — and how to pace 50 questions in 1 hour 30 minutes.
Pacing checkpoints
Our timed test uses the real length and time — 50 questions in 1 hour 30 minutes — as one block of three-choice questions. Like the real FOI test, it uses no charts or figures; teaching scenarios are given as short text.
The week before
- Take one full-length timed practice test 4–7 days out, then shorter sets and rest.
- Memorize the handbook's lists word for word: laws of learning, levels of learning, teaching-process steps and test characteristics.
- Practice telling look-alike terms apart — defense mechanisms, barriers to communication, types of practice.
- Confirm your PSI appointment, your FTN, your ID and your authorization.
During the test
- You have nearly two minutes a question — read every stem fully; scenario questions hinge on a single phrase.
- Answer in the Aviation Instructor's Handbook's terms, not everyday meanings — 'correlation' and 'perception' are technical words here.
- Distractors are usually other real terms from the same list; ask which one the scenario describes exactly.
- With three choices, eliminate the one you know is wrong first; your odds jump to 50–50.
- Mark hard questions, answer every one and come back — there's no penalty for guessing.
Keep your head
- A few nerves sharpen focus. If you freeze, take three slow breaths and reread the question.
- You need 70% — that's 35 of 50; a few unfamiliar terms won't sink you.
- Missed topics show up as ACS codes on your report, and your examiner will review them with you.
After you test
- You get your Airman Knowledge Test Report at the test center; it shows your score and the ACS codes of any knowledge areas you missed, and you'll show it to your examiner.
- A passing result is valid for 24 calendar months — complete your instructor practical test before it runs out.
- Next comes the practical test: for a flight instructor, the FIA (or other category) knowledge test and a checkride where Area I is tested orally — often by teaching a lesson; ground instructor applicants pair FOI with the matching ground instructor test.
