Build Aviation Credentials Fast: The AGI and IGI Ground Instructor Certificates
The FAA credential you earn without ever flying a checkride
The ground instructor certificates are the only FAA instructor credentials with no practical test. No flight, no oral in front of a designated examiner. You pass the written exams, apply, and the certificate is issued. For a pilot padding a resume or a career-changer getting a foothold in aviation, it is the fastest real credential on the board.
The Advanced Ground Instructor test is the gateway. Add the Instrument Ground Instructor test and you hold two teaching credentials that let you run a ground school and sign off knowledge-test students, earned entirely from written exams.
AGI, IGI, BGI: which one to bother with
- Advanced Ground Instructor (AGI). Lets you teach the aeronautical knowledge for any certificate or rating except the instrument rating.
- Instrument Ground Instructor (IGI). Lets you teach the instrument rating and the instrument knowledge inside other certificates.
- Basic Ground Instructor (BGI). A narrower version for sport, recreational, and private knowledge. Most people skip it and go straight to AGI, which is broader.
The whole path, start to certificate
- 1Pass the writtens. The Fundamentals of Instructing test, plus the AGI and/or IGI knowledge test.
- 2Apply through IACRA. Submit the application; an FSDO or an authorized official reviews it.
- 3Certificate issued. No practical test, no checkride, no flight required.
A ground instructor certificate does not carry the age-18 requirement a flight instructor does; the FAA asks that you can read, speak, write, and understand English and that you pass the required knowledge tests. Rules do get updated, so confirm the current eligibility in 14 CFR Part 61 before you apply.
What the certificate actually lets you do
- Teach ground instruction in the knowledge areas your certificate covers, up to and including a full ground school.
- Endorse a student's logbook certifying they are ready for the knowledge test in your area.
- Endorse completion of a ground training course required for a certificate or rating.
- Keep the credential current by instructing; a ground instructor who has not taught recently must meet the recency requirement before using the privileges again.
The quiet reason working CFIs get one
For a working flight instructor, this is more than a resume line. One of the routes the FAA accepts toward a Gold Seal flight instructor certificate requires holding a current ground instructor certificate, on top of the experience and student pass-rate criteria. Earning the AGI or IGI can be a deliberate step toward Gold Seal, not just a standalone credential.
Studying two writtens at the same time
The AGI and IGI banks share the instructing fundamentals and split on the technical half: advanced aeronautical knowledge for the AGI, instrument procedures for the IGI. Study the shared instructing material once, then divide your remaining time between the two technical halves. The Ground Instructor Practice Test covers the AGI knowledge areas with the FAA source on every answer, so the one thing standing between you and the certificate is the part you have already rehearsed.
