Free Practice Questions for FAA FOI

The FOI is a 50-question multiple-choice FAA Airman Knowledge Test covering the principles of teaching, learning, and instructional risk management drawn from the FAA Aviation Instructor's Handbook (FAA-H-8083-9B). It is the gateway prerequisite for every FAA aviation instructor certificate (AGI, IGI, BGI, CFI, CFII, and MEI). The exam tests pedagogical theory rather than aviation operations, so no pilot certificate or flight experience is required.

The FOI knowledge test has 50 multiple-choice questions with a 1.5-hour (90-minute) time limit. The passing score is 70%, which means you must answer at least 35 of the 50 questions correctly. FAA instructor knowledge test questions offer three answer choices rather than four, as shown in the FAA's published FOI sample questions. Scores are reported on the Airman Knowledge Test Report (AKTR) at the testing center immediately after the exam.

The FOI knowledge test costs $175, paid to PSI at the testing center when you schedule. Retakes cost an additional $175 each after you receive additional instruction and an endorsement from an authorized instructor. Most candidates pair the FOI with the AGI or IGI ($175 each), making the total ground-instructor exam cost typically $350.

The FOI is required for the initial issuance of any FAA aviation instructor certificate: AGI (Advanced Ground Instructor), IGI (Instrument Ground Instructor), BGI (Basic Ground Instructor), CFI (Certified Flight Instructor), CFII (Flight Instructor - Instrument), and MEI (Multi-Engine Instructor). Once you hold any of those certificates the FOI does not have to be retaken for additional instructor ratings.

Per 14 CFR 61.213(b) and 61.183(e), an applicant does not need to pass the FOI knowledge test if they already hold a flight or ground instructor certificate issued under Part 61, hold a current teacher's certificate issued by a state, county, city, or municipality that authorizes them to teach at an educational level of the 7th grade or higher, or are employed as a teacher at an accredited college or university. The same exemptions appear in 14 CFR 61.185(b) for the related ground-training requirement.

The FOI knowledge test is drawn from the FAA Aviation Instructor's Handbook (FAA-H-8083-9B, May 2020 edition). Chapters cover risk management and single-pilot resource management, human behavior, the learning process, effective communication, the teaching process, assessment, planning instructional activity, instructor responsibilities and professionalism, techniques of flight instruction, and teaching practical risk management during flight instruction.

FOI Airman Knowledge Test Report results are valid for 24 calendar months under 14 CFR 61.39(a)(1)(i): the knowledge test must have been passed within the 24-calendar-month period preceding the month you complete the practical test. If you do not apply within that window, you must retake the FOI. Once you hold any flight or ground instructor certificate issued under Part 61, the FOI requirement is permanently satisfied for additional instructor certificates and ratings.

No. The FOI tests teaching theory rather than aviation operations, so there is no pilot certificate, flight experience, or medical certificate requirement to take the test. You do need an FAA Tracking Number (FTN) via IACRA, English proficiency, the $175 PSI fee, and — since September 1, 2024 — an authorization to test: either an instructor logbook endorsement certifying that you completed the applicable ground training or home study course and are prepared, or a graduation certificate from an FAA certificated pilot school. The FAA Airman Knowledge Testing Matrix also sets a minimum age of 16 to take the FOI; you must be 18 for an instructor certificate to be issued.

The single authoritative source is the FAA Aviation Instructor's Handbook (FAA-H-8083-9B), available free as a PDF from faa.gov. Supplement with the FAA's official FOI Sample Questions PDF. The handbook itself cautions that commercial test preparation material emphasizes rote learning, the lowest level of learning, and should be used as a supplement to instructor-led training rather than a stand-alone learning tool. Most candidates study 15-30 hours because the content is conceptual rather than memorization-heavy.
