- The initial helicopter instructor knowledge test is the FRH, and you need 70% to pass.
- FRH has 100 scored multiple-choice questions plus possible unscored items, with 150 minutes allowed.
- FAA's 2025 FRH pass rate was 98.27% across 520 administrations, which is not a practical-test success rate.
- FOI (50 questions, 90 minutes) and the HFA add-on (25 questions, 60 minutes) also require 70%.
The Passing Score in One Look
If you are chasing the Flight Instructor Certificate with Rotorcraft Category and Helicopter Rating, the number you need to remember is 70%. That is the passing mark for the FAA knowledge test commonly associated with helicopter instructor applicants, and it is the same threshold the FAA applies to the Fundamentals of Instructing (FOI) test and the helicopter flight instructor add-on test (HFA).
The shorthand "CFI-H" is how pilots and schools commonly refer to this certificate, but the FAA's own test code for the initial helicopter instructor knowledge test is FRH, not "FIH." Searching for the right test code when you register matters, because booking the wrong test is an avoidable and expensive mistake.
| Test | Questions | Time Allowed | Passing Score |
|---|---|---|---|
| FRH (initial helicopter instructor) | 100 scored, plus possible unscored validation items | 150 minutes | 70% |
| FOI (Fundamentals of Instructing) | 50 | 90 minutes | 70% |
| HFA (add-on) | 25 | 60 minutes | 70% |
For a broader look at how these tests fit into the full qualification path, see our guide to CFI-H requirements, eligibility, and prerequisites.
How the FRH Knowledge Test Is Built
The FRH is a multiple-choice test delivered at an authorized testing center. The format has a few features worth understanding before you sit down:
- 100 scored questions. These are the items that determine your result.
- Possible unscored validation items. The FAA may seed additional questions into the test to evaluate them for future use. They do not count against you, but you cannot tell which ones they are, so treat every question as live.
- 150 minutes. That is a generous window for 100 questions, which works out to well over a minute per item even before considering any unscored extras.
- Multiple-choice only. There are no written-response or practical components in the knowledge test itself.
What 70% Actually Means
On a 100-question scored test, 70% translates to answering at least 70 scored questions correctly. That leaves room for up to 30 misses on the scored portion. Because the FAA does not publish how unscored items are distributed, the practical target is simple: aim to know the material well enough that 70 is a floor you clear comfortably rather than a number you scrape.
Why you should not study to the minimum
A 70% pass line does not mean you can ignore 30% of the content. Two reasons make that a poor strategy for helicopter instructor candidates specifically:
- The knowledge test is only one gate. After you pass it, you still face the practical evaluation, where an examiner expects you to teach and fly to the standards in the Airman Certification Standards. Gaps in knowledge show up there, in front of a person rather than a scoring engine.
- Instructor answers have downstream consequences. The material you learn for this exam is what you will teach students. Knowing it at 70% is not a sound foundation for a career built on explaining aerodynamics, emergency procedures, and risk management to others.
If you want to calibrate how demanding the content really is, read How Hard Is the CFI-H Exam? Complete Difficulty Guide 2026.
FOI, HFA, and Their Passing Marks
Many candidates focus only on the FRH and are surprised to learn there is more than one knowledge test in the picture. Which tests you must take depends on your background.
Fundamentals of Instructing (FOI)
The FOI is a 50-question, 90-minute test with a 70% passing score. It covers the teaching and learning concepts that underpin all flight instruction, independent of aircraft category.
- Required when your situation calls for it; specified exemptions exist under the regulations.
- Carries its own testing fee, separate from the FRH.
- Tests how people learn, how to teach, and how to evaluate, which later reappears in the practical test's emphasis on instructional delivery.
Helicopter Flight Instructor Add-On (HFA)
The HFA is a 25-question, 60-minute test, also scored at 70%. It applies to a different applicant situation than the initial FRH, typically someone adding helicopter instructing privileges to an existing flight instructor certificate.
- Shorter than the FRH because it targets add-on knowledge.
- Same 70% standard.
- Confirm with your instructor or the FAA testing matrix which test code applies to you before booking.
The exemption rules for FOI are specific and are spelled out in 14 CFR Part 61. Do not assume you are exempt based on hearsay; verify against the regulation or ask your certificating instructor.
Reading the 98.27% Pass Rate Correctly
The FAA's calendar-year 2025 statistics show an FRH pass rate of 98.27% over 520 administrations. That is a high number, and it is easy to misread it as a signal that the exam is trivial. Read it carefully:
- It is a knowledge test pass rate, not a practical-test pass rate.
- It is not a first-attempt figure; it reflects administrations, which can include retakes.
- It reflects a self-selected population. People taking the FRH have already earned a commercial or ATP-level helicopter background, logged substantial flight time, and typically completed ground training with an instructor who signed them off as ready.
The Knowledge Score vs. the Practical Test Standard
A common point of confusion is mixing up the knowledge test score with the standards used on the practical test. They are separate evaluations with different mechanics.
| Feature | Knowledge Test (FRH) | Practical Evaluation |
|---|---|---|
| Format | Multiple-choice at a testing center | Oral plus flight evaluation with an examiner |
| Scoring | Numerical, 70% to pass | Satisfactory/unsatisfactory against the ACS |
| Governing document | FAA knowledge test question bank and study materials | ACS FAA-S-ACS-29, effective May 31, 2024 |
| Result | Test report with a score | Completion of the certificate requirement |
Passing the FRH at 70% does not mean you will pass the checkride. The examiner evaluates you task by task against the ACS rather than averaging a score, so a weakness in one area can be disqualifying regardless of how well you did elsewhere. Our CFI-H study guide walks through preparing for both stages together.
Where Points Come From: The 13 ACS Areas
The Rotorcraft-Helicopter flight instructor ACS organizes content into 13 Areas of Operation. It is important to be precise about what this means: these are the areas of the certification standard, and they are unweighted. The FAA does not publish a percentage breakdown assigning each area a share of the FRH score, so no single area is "the biggest." Do not trust any source that claims specific domain weights for the FRH.
The 13 areas are:
- Fundamentals of Instructing
- Technical Subject Areas
- Preflight Preparation
- Preflight Lesson on a Maneuver to be Performed in Flight
- Preflight Procedures
- Airport and Heliport Operations
- Hovering Maneuvers
- Takeoffs, Landings, and Go-Arounds
- Fundamentals of Flight
- Performance Maneuvers
- Emergency Operations
- Special Operations
- Postflight Procedures
Because the weights are not published, the safest approach is balanced coverage. For a deeper breakdown of what each area expects, read CFI-H Exam Domains 2026: Complete Guide to All 13 Content Areas.
Areas that reward teaching-level understanding
Several areas are especially likely to push you beyond simple recall into explaining why a helicopter behaves as it does.
- Fundamentals of Flight: rotorcraft aerodynamics concepts, including how lift, thrust, and control inputs interact in a helicopter.
- Hovering Maneuvers: the hover is where rotary-wing instruction lives or dies, so expect emphasis on control coordination and common student errors.
- Emergency Operations: autorotation and system malfunction procedures are central to helicopter instruction and to safe teaching.
- Special Operations: the situational and environment-driven techniques that go beyond standard pattern work.
The unweighted structure means you should treat Technical Subject Areas and Fundamentals of Instructing as equal partners with the flying-oriented areas. Candidates with strong flying backgrounds sometimes underinvest in the instructing and technical-knowledge sides and get caught out.
Registration, Fees, and Test-Day Mechanics
Knowledge tests for the FRH are delivered through authorized testing centers, with PSI being the delivery provider referenced for these tests. A few mechanics to plan around:
- Fee: One current testing center lists $175 per knowledge test. Treat that as a reference point and confirm the booking price directly when you schedule, since centers set their own pricing and it can change.
- FOI is separate. When FOI is required for you, it adds another fee on top of the FRH.
- Practical and training costs are separate. Flight time, instruction, and the examiner's fee for the practical evaluation are not included in the knowledge test price.
- Authorized-center rules apply. Testing aids and materials are governed by the testing center's rules and FAA policy. Ask what you may bring before test day rather than guessing.
- Remote delivery is not verified. Plan on sitting the test at an authorized center rather than assuming an at-home option exists.
To budget the entire path rather than just the test fee, see CFI-H Certification Cost 2026: Complete Pricing Breakdown, and for scheduling, CFI-H Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
A Domain-Ordered Prep Sequence
Rather than a generic weekly template, sequence your study so that foundational teaching concepts come first and the high-consequence flight topics get repeated exposure. Here is one way to order the 13 areas across a few weeks:
Teaching foundations
- Fundamentals of Instructing: learning theory, teaching methods, and evaluation
- Technical Subject Areas: the knowledge base you will teach from
Preparation and procedures
- Preflight Preparation, Preflight Procedures, and the preflight lesson on a maneuver
- Airport and Heliport Operations, and Postflight Procedures
Maneuver-focused content
- Hovering Maneuvers and Takeoffs, Landings, and Go-Arounds
- Fundamentals of Flight and Performance Maneuvers
High-consequence topics and review
- Emergency Operations and Special Operations
- Full timed practice and review of every missed question
Practice with timed sets that mirror the FRH's 100-question, 150-minute structure, and review every miss to understand the reasoning rather than memorizing the answer. Our CFI-H practice tests are built for exactly that kind of review, and the CFI-H cheat sheet is useful for a final-days refresh.
After You Pass: Certificate and Privileges
Passing the knowledge test is one requirement among several. To be issued the certificate, you must meet the broader eligibility criteria under 14 CFR Part 61, which include:
- Being at least 18 years old and able to read, speak, write, and understand English.
- Holding a suitable commercial pilot or ATP certificate with the appropriate rating.
- Having 15 hours of pilot-in-command time in the category and class.
- Completing the required training and receiving the proper endorsements.
- Passing the applicable FRH and FOI tests and the practical evaluation, subject to specified FOI exemptions.
Certificate validity and recent experience
Certificates issued from December 1, 2024 onward do not expire. That does not mean instructing privileges continue indefinitely without upkeep: under 14 CFR 61.197, you must demonstrate recent experience within the preceding 24 calendar months to exercise instructor privileges. There is no universal continuing-education credit quota. For the career side, explore CFI-H jobs and the CFI-H salary guide, or weigh the investment in Is the CFI-H Certification Worth It?

Frequently Asked Questions
You need 70% on the FAA knowledge test, known by the code FRH for the initial helicopter instructor test. The FOI and HFA tests also use a 70% passing score.
The FRH has 100 scored multiple-choice questions, plus possible unscored validation items, with 150 minutes allowed. Treat every question as scored since you cannot identify the unscored ones.
Not necessarily. The figure is the FAA's 2025 FRH knowledge-test pass rate across 520 administrations, not a first-attempt or practical-test rate, and it reflects candidates who typically completed ground training first.
No published weighting exists. The ACS FAA-S-ACS-29 lists 13 unweighted Areas of Operation, so you should prepare across all of them rather than chasing a supposed heavy domain.
No. You must also meet the age, ratings, 15 hours PIC, training, endorsement, and practical evaluation requirements under 14 CFR Part 61. For the full overview, see what CFI-H is.
