CFI Requirements: The FAA Eligibility Checklist (14 CFR 61.183)

To be eligible for the initial Certified Flight Instructor (CFI) certificate, the FAA requires you to be at least 18 years old, able to read, speak, write, and understand English, hold a Commercial Pilot Certificate with an instrument rating, have logged at least 250 total flight hours (including 100 in powered aircraft and 50 in airplanes), have 15 hours of PIC instrument time in the category and class you're applying for, hold at least a third-class medical certificate, pass the FOI and FIA knowledge tests, receive a spin endorsement from a CFI, and pass the practical (checkride). The full regulatory citation lives at 14 CFR 61.183. The requirements list is shorter than most candidates expect — and the things that aren't required (a college degree, U.S. citizenship, a maximum age) often surprise people who've internalized airline-pilot myths. 14 CFR Part 61 reference sheet — Angle of Attack 2026 CFI eligibility checklist" />

What Are the FAA's CFI Eligibility Requirements?

The complete list, per 14 CFR 61.183: That's it. Eleven items. There is no minimum number of teaching hours, no prior instructor experience required, no college degree, no FAA "background investigation" beyond the standard medical and TSA requirements that apply to all pilots. The order most candidates work through these: items 1–5 happen by default during your Commercial/Instrument training. Items 6–9 are the "CFI prep" phase. Item 10 is the checkride. Item 11 you should already have.

The 250-Hour Total Time Requirement

You need 250 total flight hours before you can sit for the CFI checkride. This is the same number required for the Commercial Pilot Certificate, so most candidates already have it by the time they're CFI-eligible. The 250 hours break down structurally per 14 CFR 61.129(a):

• 100 hours in powered aircraft
• 50 hours in airplanes (single-engine for the standard CFI-A)
• 100 hours of pilot-in-command time
• 50 hours of cross-country PIC time
• 10 hours of complex/turbine/TAA dual instruction (Commercial requirement, carries forward)
• 20 hours of dual instruction (specific maneuvers)
• 10 hours of solo or PIC training in the maneuvers and procedures of the CFI

Most pilots who earn the Commercial Certificate have these boxes checked on day one of their CFI training. If you came through a Part 141 program, your record may be slightly different — verify against your school's training records before scheduling the practical.

The Commercial + Instrument Prerequisite

Two pilot certificates are prerequisites:

• Commercial Pilot Certificate — single-engine airplane (or whatever category/class you're seeking the CFI in)
• Instrument Rating — added to your pilot certificate

The instrument rating point catches some candidates off guard: you need an instrument rating on your pilot certificate. A CFII alone doesn't satisfy this. If you somehow obtained a CFII without ever earning the underlying instrument pilot rating, you're not eligible for the initial CFI until that rating is added to your certificate. (This is rare, but it happens.) If you want to instruct multi-engine airplanes (MEI), you need a multi-engine class rating on your Commercial. If you want to instruct in seaplanes, you need a Single-Engine Sea (SES) or Multi-Engine Sea (MES) class rating. The category/class on your Commercial drives the category/class your CFI authorizes you to teach.

The 15 Hours of PIC Instrument (Often-Missed Requirement)

This is the one that catches people. You need 15 hours of pilot-in-command instrument time in the category and class you're applying for the CFI in. This is separate from the 50 hours of instrument time required for the instrument rating (most of which is dual-given, not PIC). Per 14 CFR 61.183(d), the 15 hours must be:

• PIC — you logged it as pilot-in-command, which (for instrument time) means the airplane was in actual or simulated IMC, you were sole manipulator of the controls, and you were rated and current to act as PIC.
• In the category and class of the CFI you're applying for. So for CFI-A (single-engine airplane), you need 15 PIC instrument hours in single-engine airplanes specifically.

Many commercial candidates finish their training with most of their instrument time logged as dual (with an instructor). They have 50+ instrument hours total but only 5 or 8 hours of PIC instrument because they haven't flown solo IMC or solo simulated-IMC very often. Check your logbook now, not the week before your checkride. If you're short, the easiest way to build PIC instrument hours is to fly with a safety pilot under simulated IMC (foggles or hood) on flights you'd otherwise fly VFR. The safety pilot is required and acts as PIC for the leg if not appropriately rated; per 14 CFR 91.109(c), check the rules carefully so the time logs cleanly.

The Spin Endorsement (Unique to CFI Initial)

The initial CFI is the only flight instructor certificate that requires a logbook endorsement for spin training and competency (14 CFR 61.183(i)). CFII and MEI add-ons skip this requirement because you've already received it during your initial CFI. The spin endorsement requires:

• Spin training in an aircraft certificated for intentional spins (Cessna 152 with the right paperwork, Cessna 172 with the right paperwork, Decathlon, Pitts, Citabria, etc.)
• Demonstrated competency in spin entries, spin recoveries, and the related stall/spin awareness teaching
• A logbook endorsement from a CFI authorized to give spin training

The endorsement language is specified in FAA Advisory Circular AC 61-65. Your spin endorser typically dedicates 1–2 flights, depending on how cleanly you pick up the maneuver. A few candidates ask if they can skip the spin endorsement. They cannot. Period. The endorsement is mandatory for the initial CFI, regardless of prior experience or other certificates held.

The Two Knowledge Tests (FOI + FIA)

Two separate FAA knowledge tests are required:

• FOI (Fundamentals of Instructing) — 50 questions, 1.5 hours, 70% to pass. Tests teaching theory.
• FIA (Flight Instructor Airplane) — 100 questions, 2.5 hours, 70% to pass. Tests airplane content with an instructional frame.

Both must be passed before the practical and both are valid for 24 calendar months. If you don't pass the practical within that window, you have to retake the writtens. For the deep dive on both tests — content breakdowns, study plans, what to expect at the testing center — see The CFI Written Exams: Complete Guide to FOI + FIA.

The Medical Certificate Requirement

To exercise the privileges of a CFI certificate, you must hold at least a third-class medical certificate (14 CFR 61.23). Most candidates carry a second-class from their Commercial training; that's fine — second class meets the third-class requirement. A subtle point worth flagging: the medical is required to exercise CFI privileges, not necessarily to hold the certificate. If your medical lapses, you don't lose the CFI certificate — you just can't actively instruct until you renew. That distinction matters at career inflection points (a pilot with a medical issue can keep their CFI on file while they sort out the medical). BasicMed is not sufficient for CFI privileges. CFIs flying with BasicMed under 14 CFR 61.113(i) can act as PIC for personal flights, but the CFI privileges (giving instruction for compensation) require a third-class or higher medical.

What's NOT Required (Despite Common Myths)

Things candidates often think they need but actually don't:

• A college degree. The FAA does not require any specific education level beyond English proficiency. Many career CFIs do not hold college degrees.
• U.S. citizenship. Foreign-trained pilots can earn a U.S. CFI certificate, though they need a TSA Alien Flight Training approval before any FAA-regulated flight training in the U.S.
• A maximum age. There is no upper age limit for CFI eligibility. Many CFIs continue instructing into their 70s and 80s, provided they hold a current medical and remain medically able.
• Prior teaching experience. Zero teaching experience required. The FOI test introduces the framework; the practical demonstrates competency.
• A specific number of cross-country hours beyond Commercial requirements. The Commercial XC requirements carry forward. No additional XC time required for the CFI.
• A specific number of complex aircraft hours. Since the FAA removed the complex airplane requirement from the Initial CFI checkride, you don't need complex hours specifically for the CFI. (You probably already have them from Commercial.)
• Multi-engine experience. Not required for CFI-A (single-engine airplane). Required separately for the MEI add-on.
• Membership in a professional organization (NAFI, AOPA, etc.). Not required by the FAA, but often a smart career move.

If someone tells you a requirement that isn't in 14 CFR 61.183 or 61.23, ask for the citation. The FAA's eligibility list is the complete list.

After You Meet the Requirements: What Comes Next

The eligibility checklist is a legal threshold, not a readiness threshold. The FAA certifies you to teach. They don't make you ready to teach. There's a meaningful gap between those two things. The candidates who walk into their first paying student already comfortable, already calm, already knowing how to find the simpleness of every lesson — those candidates didn't get there by checking the FAA boxes. They got there by practicing teaching during their CFI prep, not just flying maneuvers. This is the work TotalCFI was built around: closing the gap between meeting the FAA requirements and actually being ready to instruct. The candidates I prep — Riley, Annalynn, Myla, others — pass first try because they've done both halves of the work. The legal half (the requirements above) and the teaching half (the work the FAA can't certify directly). Once you've checked the boxes on this page, you're cleared to start the real work. That's the prep work for your CFI checkride — the prep that makes the certificate matter.
