- BGI training must prepare you for 80 scored questions in 150 minutes at 70% to pass.
- Knowledge scope is defined by 14 CFR 61.213(a)(4)(i), referencing 61.97, 61.105, and 61.309.
- No pilot certificate, flight test, or logged flight hours are required for this rating.
- A first attempt needs no instructor endorsement; a retake after failure does.
What BGI Training Actually Covers
Training for the Basic Ground Instructor rating is fundamentally different from training for a pilot certificate. There's no aircraft, no checkride, and no logbook of flight hours to accumulate. What you're actually preparing for is a single computer-based knowledge test administered at PSI testing centers under FAA oversight. That distinction matters because it changes how you should structure your prep: BGI training is a study project, not a flight-skills project.
If you're still mapping out what this credential is and how it differs from other aviation ratings, start with our overview of BGI Certification or the plain-language explainer What Is BGI?. Both give useful context before you commit to a training plan.
Exam Format and Testing Mechanics
Effective preparation starts with understanding exactly what the test looks like on test day. According to the FAA testing matrix dated October 22, 2025, the BGI knowledge test consists of 80 scored questions with a time allowance of 150 minutes. Additional unscored validation items may appear alongside the scored questions, so don't assume every question you see counts toward your final score - and don't waste time trying to identify which is which, since they're indistinguishable during the test.
- Format: computer-based, multiple-choice
- Passing score: 70%
- Time allotted: 150 minutes
- Scored items: 80 questions
- Testing locations: PSI testing centers nationwide
The FAA's governing references for this exam are AC 61-65K and the FAA-CT-8080-5H testing supplement. Approved supplements and permitted calculation or navigation aids are allowed under FAA testing rules, so part of your training should include getting comfortable with whichever reference materials and aids are permitted at your test session - fumbling with an unfamiliar supplement under time pressure is an avoidable way to lose minutes.
For a deeper breakdown of how the exam is structured and what "70%" actually requires in raw question terms, see BGI Passing Score 2026: Exactly What You Need to Pass. And if you want the data behind how candidates are performing on this specific exam, our BGI Pass Rate 2026 article covers the FAA's reported administration numbers.
Key Takeaway
Treat the 150-minute window as a resource to manage, not a race to finish. With 80 scored questions, you have roughly 110 seconds per question on average - plenty of time if you know the material, tight if you're guessing repeatedly.
Knowledge Scope: What You're Required to Know
The single most important document shaping your training plan is the regulation that defines what this test actually covers. Under 14 CFR 61.213(a)(4)(i), the Basic Ground Instructor knowledge test scope references three interconnected regulatory areas: 61.97, 61.105, and 61.309. Everything you study should trace back to one of these references, and everything you skip should have a reason.
Regulatory Reference: 61.97
This section anchors the knowledge requirements tied to instrument-related instruction topics that a ground instructor may be responsible for teaching.
- Understand how this reference connects to the aeronautical knowledge a student pilot needs before specific stages of training
Regulatory Reference: 61.105
This section covers the aeronautical knowledge areas required of student pilots, which a ground instructor must be able to teach and verify.
- Expect questions framed around what a student pilot must know before solo or cross-country operations
Regulatory Reference: 61.309
This section ties into the knowledge requirements a ground instructor certificate holder must demonstrate to exercise the associated privileges.
- Review how this reference frames the instructor's own responsibility, not just the student's
Because the FAA testing matrix and regulatory citations define the scope rather than a marketing-style syllabus, the best way to organize your review is regulation-first: read the actual text of 61.97, 61.105, and 61.309, then layer supporting material on top. For a more granular walk-through organized by content area, our companion piece BGI Exam Domains 2026: Complete Guide to All Content Areas expands on how these references translate into testable topics.
Endorsements, FOI, and Retake Rules
One of the more misunderstood mechanics of BGI training involves endorsements. A first attempt at the BGI knowledge test does not require an instructor endorsement - you can walk in and test without anyone signing off on your readiness. However, if you fail that first attempt, a retake does require the applicable training endorsement before you can sit for the test again. This changes the stakes of attempt number one considerably.
Separately, Fundamentals of Instructing (FOI) is its own requirement with its own endorsement, unless an exemption under 14 CFR 61.213 applies to your situation. FOI and BGI are commonly confused because they're both prerequisites in the ground-instructor pathway, but they are distinct knowledge areas tested separately. Training for one does not automatically prepare you for the other, so build your plan around both if FOI applies to you.
Key Takeaway
Because a failed first attempt triggers an endorsement requirement for the retake, it's worth treating your first sitting as the one attempt you get without needing outside sign-off - prepare accordingly rather than treating it as a low-stakes practice run.
For the full eligibility picture - minimum age, English proficiency, and how FOI and BGI interact - see BGI Requirements 2026: Eligibility, Prerequisites & How to Qualify.
A Realistic Training Timeline
Generic study techniques like spaced repetition or timed review blocks only help when they're mapped onto BGI's actual content. Below is a training sequence built around the regulatory scope rather than arbitrary calendar weeks - adjust the pace to your own schedule, but keep the order, since later material builds on the regulatory foundation established early.
Regulatory Foundation
- Read 61.105 in full and note every aeronautical knowledge item a student pilot must demonstrate
- Cross-reference 61.97 for how instrument-related knowledge intersects with instruction duties
Instructor-Specific Requirements
- Study 61.309 closely, focusing on what the ground instructor certificate holder - not the student - must know
- Identify overlap and distinctions between what students must know and what instructors must be able to teach
Test Simulation
- Practice under a strict 150-minute clock using multiple-choice question sets
- Get comfortable with whichever approved supplements and calculation aids you plan to use on test day
Final Review
- Revisit weak areas identified during simulated testing
- Confirm testing center logistics through PSI and review FAA-CT-8080-5H supplement contents one final time

Who Needs BGI Training
Because there's no pilot certificate, flight test, or logged flight-hour requirement attached to this rating, candidates come from a wider range of backgrounds than many other aviation credentials. Some are aspiring flight instructors building toward more advanced instructor ratings; some are aviation educators working in ground-school settings; others are pursuing it as a standalone credential tied to specific ground-instruction roles. The minimum age to sit for the knowledge test is 16, though certificate issuance itself requires reaching age 18 and demonstrating English proficiency.
| Requirement | Detail |
|---|---|
| Minimum age to test | 16 |
| Minimum age for certificate issuance | 18 |
| English proficiency | Required for issuance |
| Pilot certificate required | No |
| Flight test required | No |
| Logged flight hours required | No |
This flexibility means training plans should be personalized. If you're weighing whether the time investment makes sense for your goals, our analysis in Is the BGI Certification Worth It? Complete ROI Analysis 2026 and the practical outlook in BGI Jobs can help frame the decision before you commit training hours. Cost is another factor worth planning around early - see BGI Certification Cost 2026: Complete Pricing Breakdown for what to budget beyond the test fee itself.
After You Pass: Privileges and Currency
Passing the knowledge test isn't the finish line for exercising ground-instructor privileges - it's the entry point. The ground-instructor certificate itself has no expiration date once issued, which is a meaningful advantage over time-limited credentials. But there's a catch worth building into your long-term plan: exercising the certificate's privileges requires recent experience within the preceding 12 calendar months under 14 CFR 61.217.
Understanding the full weight of preparation before you sit for the test - including how difficult candidates generally find the material - is worth reviewing before you finalize a training timeline. See How Hard Is the BGI Exam? Complete Difficulty Guide 2026 for that context, and check BGI Exam Dates 2026: Testing Windows, Deadlines & Scheduling when you're ready to schedule your PSI testing center appointment.
Once you've built your regulatory foundation, running through realistic practice questions at our practice test platform is one of the most efficient ways to confirm you're ready before you pay for an official attempt. Working through timed sets on the practice site also helps you get a feel for the 150-minute pacing well before test day, and revisiting missed questions there can point you straight back to the specific regulatory section - 61.97, 61.105, or 61.309 - that needs another pass.
