- Frequently Asked Questions
- The PSI test voucher is listed at US$175 plus tax, and initial IGI testing requires no instructor endorsement.
- The test is 50 questions in 150 minutes with a 70% passing score; FAA's CY2025 data shows a 99.71% pass rate.
- The rating carries no expiration date, but exercising privileges needs one 61.217 recent-experience activity every 12 calendar months.
- No credential-specific salary premium has been verified, so ROI depends on your teaching setting, not the rating alone.
What You Are Actually Buying With an IGI Rating
Before running any return-on-investment math, pin down the product. The Instrument Ground Instructor (IGI) rating is an FAA ground instructor rating that lets you provide ground instruction on instrument flight topics and give the endorsements that go with that instruction. It is not a flight instructor certificate. It does not authorize you to teach in an aircraft, and it is not the same thing as holding an instrument rating as a pilot.
The knowledge test itself carries the code IGI and is officially named Ground Instructor Instrument. That naming matters when you read competitor pages or forum posts, because several unrelated credentials share the three letters. If you want the full definition before going further, start with What Is IGI Certification? and come back.
The rating's value is therefore narrow and specific: it is a low-barrier, FAA-issued teaching credential for instrument-flight knowledge. Whether it is "worth it" depends on whether you have a place to use that teaching authority, and this article is built around that question.
The Cost Side of the Ledger
The direct costs of the IGI path are unusually small compared with most aviation credentials, because there is no checkride and no flight time requirement attached to this rating.
Fixed and Known Costs
- Test voucher: PSI publishes an FAA Airman Knowledge Test voucher price of US$175 plus applicable tax. This is the voucher price only, not a prep course and not the total for any separately required Fundamentals of Instructing (FOI) test.
- No instructor endorsement for the first attempt: Initial IGI testing requires no instructor endorsement or other written authorization, so you are not paying for sign-off time to sit the test.
- Administrative prerequisites: You need an FAA Tracking Number (FTN) through IACRA and acceptable identification. Both are free to obtain, but you must have them in hand before test day.
Variable Costs You Control
- Preparation materials: The market includes Sheppard Air, Gleim Aviation, ASA, King Schools and OpenExamPrep, among others. Prices vary widely and change often, so compare current offers rather than relying on any figure printed here.
- FOI requirement: Under 14 CFR 61.213, certificate eligibility includes FOI knowledge unless you are exempt. Exemptions include holders of a ground or flight instructor certificate, holders of qualifying teaching certificates permitting teaching at grade 7 or higher, and teachers employed at accredited colleges or universities. If none of those describe you, budget for the FOI test and its preparation separately.
- Retest costs: A failed attempt means another voucher and the required instructor training or proficiency endorsement, plus the failed Airman Knowledge Test Report.
For a line-by-line breakdown, see IGI Certification Cost 2026: Complete Pricing Breakdown. The headline point for ROI purposes is that the unavoidable cash outlay is modest and the only large variable is how much you spend on preparation.
The Effort Side: What the Test Demands
Money is only half the investment. The other half is the hours you spend learning enough instrument-flight content to teach it, and the FAA's published test parameters help you size that.
Test Mechanics
- Format: Computer-delivered multiple choice at a PSI-authorized knowledge-testing center.
- Length: 50 questions, excluding any unscored validation items. The FAA table does not establish how many additional unscored items may appear, so do not plan around a specific number.
- Time: 150 minutes. Some competitor pages print a two-hour timer; the FAA matrix says 150 minutes.
- Passing score: 70%.
- Minimum testing age: 16, although certificate eligibility under 61.213 requires age 18.
- Test aids: Approved calculators and navigation aids are allowed subject to memory clearing and proctor approval, along with the supplied testing supplement (FAA-CT-8080-3F). Outside study materials are prohibited. FAA Order 8080.6H, chapter 3, governs these rules.
What the Pass Data Says
The FAA's CY2025 Airman Knowledge Test Volume Report records 2,751 IGI test administrations, a 99.71% passing rate and a 93.11% average score. Read those numbers carefully. They are 2025 administration-level results, not a 2026 figure and not a first-attempt-only pass rate. They also describe a self-selected population, since many candidates already hold an instrument rating or flight instructor background before sitting the test.
The honest takeaway for ROI is that the test is rarely the bottleneck. The risk of paying twice for a voucher is low if you prepare reasonably. For a deeper look, read IGI Pass Rate 2026: What the Data Shows and How Hard Is the IGI Exam? Complete Difficulty Guide 2026.
Where the Value Comes From
Because the rating does not expire and has a low entry cost, its value is mostly option value: it lets you teach instrument knowledge legitimately and, in some settings, to be paid for it. Here are the concrete places that value shows up.
Teaching Settings Where the Rating Has a Use
- Flight schools and Part 141 or Part 61 operations that want ground instruction for instrument students delivered by someone other than the flight instructor.
- Aviation programs at colleges and universities, where instrument ground content is a standard course component.
- Independent ground-school offerings, including evening and weekend instrument courses.
- Private tutoring for instrument students preparing for their own knowledge test.
Job titles and openings vary by region and employer, and this article does not claim any specific hiring volume. For a survey of the kinds of roles that exist, see IGI Jobs.
Indirect Returns
Some of the strongest returns are not wages at all. Teaching a subject is the fastest way to find the holes in your own understanding, and the IGI body of knowledge maps closely onto what instrument pilots need. If you are an instrument pilot or aspiring flight instructor, the study process itself sharpens skills you will use in the cockpit.
Domains That Translate Into Real-World Skill
The ten aeronautical-knowledge areas in 14 CFR 61.65(b) are statutory headings, not an FAA-weighted blueprint, but several map directly to what students ask in a ground session.
- Domain 5: Use of IFR en route and instrument approach procedure charts, the staple of every instrument ground lesson.
- Domain 6: Procurement and use of aviation weather reports and forecasts, including forecasting weather trends from reports and personal observation.
- Domain 3: Air traffic control system and procedures for instrument flight operations.
- Domain 9 and 10: Aeronautical decision making and judgment, plus crew resource management, which are increasingly central to how instrument training is framed.
Full coverage of all ten areas is in IGI Exam Domains 2026: Complete Guide to All 10 Content Areas.
Salary Reality: What We Can and Cannot Say
This is the section where most ROI articles overreach, so here is the careful version. There is no verified, credential-specific salary premium for holding the IGI rating. Ground instruction pay depends on the employer, the region, whether the work is hourly or salaried, and whether you also hold other certificates such as a flight instructor certificate.
It helps to separate two questions that get blurred together:
- Eligibility: Does the IGI rating make you legally able to give instrument ground instruction? Yes, that is exactly what it does.
- Compensation: Does it raise your pay? That depends entirely on whether an employer values it and pays accordingly, and no published figure establishes a premium.
Broad ground-instructor job pay is not the same as pay attributable to the IGI rating. Anyone quoting a precise hourly rate for "IGI holders" is either importing data from another credential or guessing. For the careful treatment, read IGI Salary Guide 2026: Complete Earnings Analysis, and use local job listings to price your own market.
IGI vs IRA vs FII vs AGI: Choosing the Right Credential
Part of the ROI question is whether the IGI is the right credential at all. These four are related but distinct, and they do not share an identical exam. The IGI test is specific to the Ground Instructor Instrument knowledge test code.
| Credential | What It Is | Who It Fits |
|---|---|---|
| IGI (Ground Instructor Instrument) | FAA ground instructor rating for instrument ground instruction; knowledge test only, no flight test required for this rating | People who want to teach instrument ground topics without flight instruction authority |
| IRA (Instrument Rating Airplane) | Pilot instrument rating knowledge test used toward flying IFR yourself | Pilots who want to fly under instrument flight rules |
| FII (Flight Instructor Instrument Airplane) | Flight instructor knowledge test for instrument flight instruction | Flight instructors who want to teach instrument flying in the aircraft |
| AGI (Advanced Ground Instructor) | A separate ground instructor rating with its own scope | Those seeking broader ground instruction authority than instrument alone |
The practical rule: if your goal is to teach instrument knowledge on the ground and you do not hold or want a flight instructor certificate, the IGI is the most direct and cheapest route. If you want to teach in the airplane, the IGI is not a substitute for flight instructor credentials. Section 61.213 does not require a pilot certificate, flight-time minimum or practical flight test for this ground rating, which is exactly why the barrier to entry is so low.
A Rating That Never Expires, With a 12-Month Catch
One of the strongest ROI arguments for the IGI is durability. Under 14 CFR 61.19(e), ground instructor certificates are issued without an expiration date. You pay once and the credential stays on your record.
But certificate permanence is not the same as being current to teach. To exercise your privileges, 61.217 requires one of the recent-experience alternatives within the preceding 12 calendar months:
- Qualifying ground-instructor activity,
- Qualifying flight-instructor activity,
- An approved flight instructor refresher course, or
- A proficiency endorsement from an authorized instructor.
This is not a fixed continuing-education-unit requirement, and you should not budget for CEUs. The practical implication for ROI is that a certificate sitting unused still exists, but you cannot lean on it to teach without staying current. People who teach regularly satisfy this requirement naturally. People who earn the rating as a one-time résumé line may need a refresher or endorsement later, which is a small recurring cost to factor in.
Key Takeaway
Treat the IGI as a durable asset that needs light upkeep. If you plan to teach, your regular activity keeps you current. If you plan to bank the rating for later, price in a proficiency endorsement or refresher before you resume instructing.
Who Gets the Best Return and Who Should Skip It
Strongest Fit
- Instrument-rated pilots who want to teach without committing to the cost and time of a flight instructor certificate.
- Aspiring flight instructors who want to start earning teaching experience and test their own knowledge before pursuing flight credentials.
- Aviation school staff and academics who already qualify for the FOI exemption and can add the rating with minimal friction.
- Retired or part-time aviators looking for flexible, ground-based teaching work.
Weak Fit
- Anyone expecting a guaranteed salary bump. No verified premium exists.
- Candidates who want to teach in the airplane. The IGI does not grant flight instruction privileges.
- People with no local outlet. If there is no flight school, college program or student demand within reach, the rating has little to attach to.

A Domain-Weighted Prep Plan That Protects Your ROI
The cheapest way to protect your return is to pass cleanly on the first attempt and avoid the retest voucher and endorsement. The FAA does not publish weighted domain percentages for this test, so do not allocate time based on invented percentages. Instead, schedule by dependency: learn the regulatory and procedural foundation first, then the skills that build on it.
Rules and Procedures Foundation
- Work through Domains 1 and 2: the IFR-relevant regulations and the corresponding Aeronautical Information Manual material.
- Get your FAA Tracking Number through IACRA while you are at it.
Charts, Navigation and ATC
- Cover Domains 3, 4 and 5: air traffic control procedures, IFR navigation and approaches, and en route and approach chart use.
- Practice with the FAA testing supplement, since it is what you will have on test day.
Weather and Operations
- Cover Domains 6, 7 and 8: weather reports and forecasts, safe IFR operation, and critical weather and windshear avoidance.
Judgment, Crew Coordination and Full Review
- Cover Domains 9 and 10: aeronautical decision making and crew resource management.
- Finish with timed practice sets against the 150-minute limit and review weak areas.
If you want a structured walkthrough, IGI Study Guide 2026: How to Pass on Your First Attempt goes deeper, and IGI Cheat Sheet 2026: One-Page Review of Must-Know Facts is useful for the final pass. When you are ready to simulate the exam experience, use the IGI practice tests and run several timed sessions before scheduling your appointment.
Since your goal is to teach, go beyond memorizing answers. Be able to explain why a given approach chart interpretation or weather decision is correct, because that is the skill the rating is meant to certify in practice.
The Verdict
So, is the IGI certification worth it? For the right person, yes, and the reasoning is simple. The entry cost is small (a US$175 plus tax voucher, plus prep and possibly an FOI test), the knowledge test is manageable given the FAA's published 2025 pass data, the certificate never expires, and the rating requires no flight time or practical test.
The caveat is equally clear. The return is not automatic. No verified salary premium is tied to the rating itself, and your payback depends on having a real teaching outlet, whether paid or as a stepping stone toward flight instruction. Verify local demand, price your own break-even, and treat the 12-month currency requirement as part of the ongoing cost of using the rating.

Frequently Asked Questions
PSI publishes an FAA Airman Knowledge Test voucher price of US$175 plus applicable tax. That is the test voucher only. It does not include preparation materials or any separately required FOI test, so your total will be higher.
Not for your initial attempt. Initial IGI testing requires no instructor endorsement or other written authorization. You do need an FAA Tracking Number through IACRA and acceptable identification. A retest after failure does require the failed Airman Knowledge Test Report and the required instructor training or proficiency endorsement.
The certificate itself has no expiration date under 14 CFR 61.19(e). However, to exercise its privileges you must meet one of the recent-experience alternatives in 61.217 within the preceding 12 calendar months, such as qualifying instructor activity, a flight instructor refresher course or a proficiency endorsement.
No credential-specific salary premium has been verified. Pay for ground instruction depends on the employer, region and whether you hold other certificates. Estimate your own return using local listings rather than relying on any single published figure.
No. The IGI is the Ground Instructor Instrument knowledge test for a teaching rating, while the IRA test supports a pilot's own instrument rating. They are distinct credentials with separate exams, and the IGI does not authorize flight instruction.
