About the CFII test

The Flight Instructor (Instrument) knowledge test covers teaching instrument flying: IFR procedures and approaches, the instrument system, and how to instruct instrument students effectively.

You take it if you are a flight instructor adding the instrument instructor (CFII) rating so you can provide instrument flight training and instrument endorsements.

The Flight Instructor, Instrument (CFII) knowledge test has 50 questions and requires 70% to pass, which is 35 correct. It is a computer-based test given at a PSI test center for a $175 fee. You must pass with 70% or higher before taking the practical test (checkride) or oral and practical for your certificate.

Aviator IQ's bank for this test holds 750 practice questions across 16 categories, each grounded in Instrument Flying Handbook. Every question shows an explanation and cites the section it comes from, so a wrong answer teaches the rule rather than just marking you down.

A passing knowledge-test result is one requirement. A certificated instructor still endorses you, and the practical test or checkride is separate. Aviator IQ prepares the knowledge test so that step is behind you.

Common questions about the Flight Instructor, Instrument (CFII) Test

The Flight Instructor, Instrument (CFII) knowledge test has 50 questions and is delivered on a computer at a PSI testing center. The passing score is 70%, which means you need 35 correct. Our bank holds 750 practice questions across 16 subject categories, so you can drill well past the length of a single sitting.

A sitting at a PSI testing center runs about $175, and if you do not pass you pay that fee again for each retake. Aviator IQ Pro is $29 paid once, so the goal is to walk in ready and clear the 70% mark on the first attempt.

Every question is written from Instrument Flying Handbook and the other FAA source documents for this certificate. Each one carries a verbatim quote from the source, and that quote is checked against the document before the question ships, so a wrong answer teaches the rule rather than just marking you down. When the FAA reissues a handbook, the questions that cite it are pulled for review.

No. Aviator IQ is test preparation only and is not affiliated with the FAA. Under 14 CFR § 61.35 the authorization to take the official knowledge test comes from a certificated instructor or an approved course, not from a prep tool. The knowledge test is also only one requirement: the practical test or checkride is separate.

No. Pro is $29 paid one time and never renews. It unlocks every subject category, all practice runs, the full-length exam simulator, hints, and the readiness score. There is no monthly or annual charge.
