CFII

The instrument rating test samples the flying pilot's knowledge. The CFII test samples your ability to teach that same body of knowledge, plus instructor-specific material on endorsements, logbook entries, analysis of common student errors, and the practical test standards you will apply to someone else.

It has an oral portion and a flight portion. The examiner plays a student and expects you to teach, assess, and correct rather than simply perform. Expect to explain airworthiness and weather decisions, then demonstrate instructional proficiency in attitude flying, holds, approaches, and partial-panel work from the right seat.

The FAA publishes the current passing score, question count, and testing time for each knowledge test in its official references, and those figures are updated periodically. Check the FAA website and your testing center's published information before scheduling so you are working from the current numbers.

Retake rules are set by regulation and change from time to time, including endorsement and waiting-period requirements after a practical test failure. Look up the current requirements in the FAA regulations and the applicable airman certification standards rather than relying on what another candidate told you.

The instructor certificate itself does not expire, but instructor privileges are renewed on a cycle through a refresher course, a practical test, or documented activity. Instrument instructor privileges depend on maintaining your own instrument currency as well, so track both sets of requirements separately.

Start with the instrument content you must teach, then layer on instructional technique: lesson planning, demonstration-performance, and error analysis. Finish with the regulatory and endorsement material. Practicing explanations out loud as you review exposes content gaps faster than reading does.

Usually not from missing trivia. Common causes are weak instructional analysis - being unable to explain why a student made an error and what to do about it - and shaky knowledge of endorsements, currency, and the standards the examiner is holding you to. Being able to fly the maneuver is not the same as being able to teach it.

No. You need access to an instrument-equipped aircraft and a qualified instructor for the right-seat practice, but you do not need to have logged instrument instruction you gave before the checkride. Many applicants build teaching experience by briefing and critiquing fellow pilots during preparation.

It depends heavily on how recently you flew instruments and how much instructional experience you already have. Build a schedule around your own currency and comfort teaching each task out loud, and get an honest assessment from a CFII early so you know where the gaps actually are.
