What it allows you to do
Passing the FOI allows you to apply for both Ground Instructor (AGI/IGI) and Flight Instructor (CFI/CFII) certificates.
Exemption
You are exempt if you already hold a current FAA Ground or Flight Instructor certificate, or if you are a certified high school or college teacher.

// ADVANTAGES FOR INSTRUCTORS
By passing three knowledge tests (FOI, AGI, IGI) and visiting an FAA office, you can earn Advanced and Instrument Ground Instructor certificates without aircraft rental or examiner fees.
A ground instructor certificate with an advanced or instrument rating is one of the qualifying criteria for the FAA Gold Seal Flight Instructor designation, together with student pass-rate requirements.
With an AGI and IGI you can charge for ground instruction, run test-prep classes, and endorse students for knowledge tests while you are still building flight hours or completing your Commercial certificate.
