What Is A BGI?

What a BGI Actually Is

A BGI, or Basic Ground Instructor, is a rating on an FAA ground-instructor certificate earned by passing the Ground Instructor (Basic) knowledge test. It's a distinct credential from a pilot certificate or a flight instructor rating - there's no flight test, no logged flight hours, and no requirement to hold a pilot certificate at all. The rating exists to authorize a person to provide ground instruction and sign specific training endorsements without ever leaving the classroom.

If you've landed here after searching several variations of the acronym, it's worth being precise: this article, and this site, cover the Basic Ground Instructor rating governed by 14 CFR Part 61 and administered through PSI testing centers - not any other credential that happens to share the same three letters. For a broader breakdown of the acronym itself, see What Is BGI? and BGI Meaning.

What the Certificate Lets You Do

A ground-instructor certificate with the basic rating allows the holder to provide ground instruction and, importantly, to sign certain endorsements that a student needs before taking an FAA knowledge test or continuing training. Because the rating is scoped by 14 CFR 61.213(a)(4)(i), the privileges are tied specifically to the knowledge areas the exam covers - the BGI is not a blanket authorization to teach every subject at every pilot level.

Two things the certificate does not automatically include:

• Fundamentals of Instructing (FOI): This is a separate knowledge requirement with its own endorsement, unless an exemption under 61.213 applies to the applicant.
• Flight instruction privileges: A BGI is ground-only. Anyone wanting to log flight time as an instructor needs a flight instructor certificate, which is an entirely different process.

For the full list of what you can and can't do with the rating, our dedicated BGI Certification and What Is BGI Certification? pages go deeper into privilege boundaries and how they interact with other Part 61 certificates.

Exam Format: Questions, Time, and Score

The BGI knowledge test is a computer-based, multiple-choice exam delivered at PSI testing centers. Per the FAA testing matrix dated October 22, 2025, the exam consists of 80 scored questions with a 150-minute time limit. The FAA may include additional unscored validation items mixed into the test, which candidates cannot distinguish from scored questions - so every item should be treated as if it counts.

A passing score is 70%. That threshold applies uniformly; there's no curve or domain-by-domain minimum published in the testing supplement. For a full breakdown of exactly how that percentage translates into missed questions and what a comfortable margin looks like, see BGI Passing Score 2026: Exactly What You Need to Pass.

That 70.73% pass rate across 41 administrations in 2025 is a small sample compared to major pilot certificate tests, which is one reason candidates often underestimate how specific the knowledge scope is. We break down what that number actually implies for a first-time test-taker in BGI Pass Rate 2026: What the Data Shows, and whether the exam is genuinely difficult or just narrow in How Hard Is the BGI Exam? Complete Difficulty Guide 2026.

Knowledge Scope and Regulatory References

The content boundary for the BGI test is defined in 14 CFR 61.213(a)(4)(i), which ties the exam's knowledge scope to the aeronautical knowledge requirements referenced in 61.97, 61.105, and 61.309. In practical terms, this means the BGI test draws on the same underlying knowledge base that a ground instructor would need to teach toward the pilot certificate levels connected to those sections - you're being tested on your ability to instruct that material, not just recall it as a pilot applicant would.

The official reference documents you should be studying from are:

• AC 61-65K - the advisory circular governing certification requirements for pilots and instructors, including ground instructors.
• FAA-CT-8080-5H - the listed testing supplement associated with the current BGI testing matrix.
• The FAA testing matrix dated October 22, 2025 - the authoritative source for the current question count, time allowance, and structure.

Approved supplements and permitted calculation or navigation aids are allowed during the test under standard FAA testing rules, so it's worth confirming what you're permitted to bring before test day rather than assuming.

Who Actually Pursues a BGI

Because the rating requires no pilot certificate, no flight hours, and no flight test, it attracts a mix of people who wouldn't otherwise be on a path toward flight instruction:

• Flight school ground school instructors who teach classroom or online private-pilot and recreational-pilot ground curricula.
• Aviation program staff at colleges and training centers who need signing authority for specific endorsements without pursuing a flight certificate.
• Career-track flight instructor candidates who use the BGI as an early, low-barrier credential before or alongside CFI training.
• Aviation enthusiasts and career-changers who want a credential proving instructional knowledge without the cost and time of flight training.

Eligibility, Age, and Endorsements

Eligibility for the BGI is more permissive than most FAA certificates, but there are specific age and endorsement rules that trip people up.

That distinction between a first attempt and a retake matters for scheduling - if you fail, you can't simply rebook the next available PSI slot without first securing the correct endorsement. This is one of several eligibility details covered comprehensively in BGI Requirements 2026: Eligibility, Prerequisites & How to Qualify.

Registration and Testing Mechanics

The BGI knowledge test is administered at PSI testing centers, the FAA-authorized network used for airman knowledge tests. Registration follows the standard PSI process: create an account, select the correct exam code for the Ground Instructor (Basic) test, and schedule at a center with availability near you.

A few mechanics worth knowing before you book:

• The exam is computer-based and multiple choice, delivered on-site at the testing center - there's no remote-proctoring option described in current FAA guidance for this test.
• Approved supplements and permitted calculation or navigation aids are allowed, but bring only what's explicitly authorized; testing centers can and do turn away unapproved materials.
• The current testing matrix, dated October 22, 2025, plus AC 61-65K and the FAA-CT-8080-5H supplement, are the documents that govern exactly what's tested and how - treat them as your primary sources over any third-party summary, including this one.

If you want a scheduling-specific breakdown - how far in advance to book, how retake waiting periods interact with endorsement requirements, and how to plan around PSI availability - see BGI Exam Dates 2026: Testing Windows, Deadlines & Scheduling. You can also get comfortable with the test interface and question style ahead of time using the practice exams on the main BGI practice test platform.

Keeping the Certificate Active

Unlike many aviation credentials, the ground-instructor certificate itself does not expire once issued. That's a meaningful advantage over ratings that require periodic renewal paperwork or recurrent testing just to stay on the books.

In practice, this means someone could hold a BGI for years without teaching, and the certificate would still technically be valid - but they would not be legally permitted to exercise its privileges (like signing an endorsement) until they satisfy the 61.217 recent-experience requirement again. This distinction between "certificate validity" and "privilege currency" is easy to miss and worth building into any long-term plan around using the rating professionally.

A Realistic Way to Prepare

Because the BGI draws its scope from cross-referenced regulatory sections rather than a single standalone syllabus, the most efficient preparation sequence is to study by regulatory citation first, then by question style.

This is intentionally a light framework rather than a generic study system - the goal is to spend your limited prep time on the regulatory cross-references and question style that are unique to this exam, not on generic test-taking tricks. A more detailed, step-by-step version of this plan, including how much time to allocate per topic, is in BGI Study Guide 2026: How to Pass on Your First Attempt.
