CF Exam Domains 2026: Complete Guide to All 7 Content Areas

How the Seven Written Study Areas Work

The Certified Farrier (CF) credential is issued by the American Farrier's Association (AFA), and its written preparation is organized around seven study subjects: Bones and Joints, Hoof Structure, Tendons and Ligaments, Blood Circulation, Pathology, Horseshoes, and Conformation, Gaits, and Physiology. These headings come from the AFA's 2022 Certified Farrier guide, which is the dated issuer document that lays out what a candidate should study for the written examination.

It is worth being precise about what that means. The seven subjects are unweighted study headings. The AFA materials we reviewed do not publish percentages for each area, and we have not found a verified 2026 exam blueprint that assigns weights or says which area is largest. Anyone quoting "Domain 3 is 22% of the exam" for this credential is making it up. The honest approach is to prepare for all seven and let your own practice-test results show you where you are weakest.

The AFA's own tester manual describes a supervised, closed-book paper written assessment alongside in-person skills work. That tells you something about the style of preparation required: you will not be able to look anything up, so terminology, anatomy, and cause-and-effect reasoning have to live in your head. For the broader picture of how the credential is structured, see What Is CF Certification? and the CF requirements guide.

Domain 1: Bones and Joints

This is the skeletal foundation of everything a farrier does. A farrier who cannot name the structures inside and above the hoof cannot reason about why a horse moves the way it does or why a particular trim or shoe helps or harms.

Why this area earns its place first

Bone and joint knowledge is the vocabulary layer. Later questions on pathology, shoeing, and conformation assume you already know the names and positions. If you hesitate on whether the pedal bone sits above or below the navicular bone, a question on laminitic rotation or navicular syndrome becomes much harder than it needs to be. Build this layer carefully and revisit it often.

Domain 2: Hoof Structure

Where Bones and Joints covers what is inside, Hoof Structure covers the capsule and the living tissues that connect it to the limb. This is the most farrier-specific of the seven areas, because it is the structure you actually work on every day.

Expect to connect structure to function. A good question here is rarely "name this part" in isolation; it is more likely to ask what a given structure does or what happens when it is compromised. Practice explaining each part in one sentence of function, not just labeling it on a diagram.

Domain 3: Tendons and Ligaments

The soft-tissue structures that support and move the lower limb are a classic source of both exam questions and real-world lameness cases. This area rewards candidates who study origins, insertions, and functions as a connected system rather than as a list of names.

The last point is where this domain meets your practical work. Raising or lowering the heel, changing breakover, and altering hoof balance all shift strain between structures. Being able to reason about that, rather than memorize it, is what separates a confident answer from a guess. Pair this section with your notes on Horseshoes later in the guide.

Domain 4: Blood Circulation

Circulation is the area candidates most often underestimate, because it feels less hands-on than shoeing. But the hoof is a highly vascular structure, and circulation underlies growth, healing, and several of the most serious foot conditions.

Domain 5: Pathology

Pathology covers the diseases, injuries, and defects a farrier is likely to encounter or need to recognize. Because it builds on the first four areas, it is best studied after your anatomy is solid.

For each condition, build a short card: what it is, what causes it, what you would observe, and what the farrier can or cannot do about it. That last element matters because exam questions in this area often test judgment about scope of practice, not just recognition of symptoms. Candidates comparing credentials and career paths may also find the CF jobs overview useful for seeing how these skills are applied.

Domain 6: Horseshoes

This is the area where the written exam comes closest to the practical assessments. It covers shoe types, materials, fitting principles, and the reasoning behind choosing one shoe or modification over another.

Written knowledge vs. forge-side skill

Reading about shoes and making them are different skills, and the certification tests both. The written portion checks that you understand the reasoning; the practical horseshoeing and shoe-display/oral components check that you can execute and defend your work. Study the "why" behind every shoe feature, because that reasoning is what you will need to articulate at the display stage as well. For the training side of this, see our overview of CF training.

Domain 7: Conformation, Gaits, and Physiology

The final study area zooms out from the foot to the whole horse. It covers how the body is built, how it moves, and how its systems function, all of which determine how a farrier should read and respond to an individual animal.

Conformation questions reward observational thinking. If a horse toes out, what does that predict about how the foot lands and wears, and what might a farrier adjust? Practicing that chain of reasoning with real or photographed horses is more effective than rote memorization. You can pressure-test this reasoning with questions on our practice test site.

Where the Written Content Meets the Practical Components

Written preparation does not replace the practical shoeing or horseshoe-display assessments. All three components are required for the Certified Farrier credential. The seven subjects above are the knowledge base that supports your hands-on work, but passing the paper exam is only part of the process.

The tester manual describes certified-level practical and display scoring at around 7, along with a "mulligan" provision for the CF level, but these details are subject to confirmation against the current guide. Do not rely on a summary, including this one, for scoring rules; check the latest official document. For more on scoring questions, see our CF passing score guide, and for the overall difficulty picture, read How Hard Is the CF Exam?

Sequencing the Seven Areas in Your Prep

You only need one structured plan, and the best order follows the logic of the content itself: anatomy first, then the things that go wrong with anatomy, then the tools and whole-horse context. Here is one way to sequence it.

The reason for this order is dependency: Pathology and Horseshoes questions assume you already know the anatomy, so studying them first creates gaps. If you are building a longer plan, our CF study guide walks through preparation in more depth, and the CF cheat sheet is useful for final review.

What Is and Isn't Verified for 2026

Being upfront about the limits of public information protects you from wasted effort and from bad advice. Here is where things stand based on the sources we reviewed.

• Verified: The seven written-exam study subjects are listed in the AFA 2022 Certified Farrier guide. Written, practical horseshoeing, and shoe-display/oral components are all required. The written assessment is described as supervised and closed-book on paper. At least one year of horseshoeing experience is a stated requirement.
• Not verified: A 2026 weighted exam blueprint, the largest content area, the live written question count, the scored/unscored split, current national component time limits, the numerical written cutoff, calculator policy, and remote or adaptive testing policies.
• Not publicly disclosed: A current national pass rate. See our CF pass rate article for how to think about this without inventing numbers.

On cost, the exam fee for 2026 for members and nonmembers has not been verified. A figure in the tester manual is explicitly a March 2016 historical schedule and should not be treated as a current quote, and host charges at an event may apply. The official guide has been listed at $15.95, but that is the price of the guide, not an exam fee. Check the AFA directly and see our CF certification cost breakdown for how to budget. Renewal fees, validity period, and continuing-education totals also could not be verified, so confirm those with the AFA before you plan around them.
