How to write an IRAC answer.

IRAC — Issue, Rule, Application, Conclusion — is the format that organizes every law school exam answer and legal memo. Understanding what each section does, why order matters, and how to allocate time and words across sections is the difference between an answer that reads like sharp legal analysis and one that reads like a fact summary with a conclusion bolted on. This guide covers all of it: the structure, the common failure modes, and the issue-spotting discipline that makes IRAC actually work under exam pressure.

What IRAC is — and what each letter does

IRAC is a writing structure, not a style. A well-written IRAC answer can be conversational or formal, brief or detailed — what matters is that each section does its distinct job. The Issue frames the legal question. The Rule states the governing law. The Application maps the rule onto the specific facts. The Conclusion answers the Issue directly. Strip any section out and the analysis collapses.

Law students often get the first two sections right early on. They can identify an issue and cite a rule. The grades are made and lost in the Application — typically the longest section and where most of the rubric points live. A weak Application restates the rule or summarizes the facts without connecting them. A strong Application says: 'Here, [specific fact from the problem] establishes [element of the rule] because [reason], but [counterargument]...' It uses the facts as evidence for a legal conclusion.

The Conclusion is not the place for new analysis. Its job is to answer the Issue in one or two sentences — 'Therefore, a contract was formed' or 'Therefore, Pat's claim for negligence will likely fail on the breach element.' If you find yourself adding reasoning in your Conclusion, move it to Application.

Most exam fact patterns contain several issues, not one — so real exam answers are not a single IRAC but a chain of them, often nested. You'll see this written as IRAAC (two competing applications), CRAC (conclusion-first, common in legal writing), or MIRAT, but they are all the same skeleton: name the question, state the law, argue the facts both ways, answer. The variation that matters most for exams is breaking a big claim into its elements and running a mini-IRAC on each contested element. Negligence isn't one issue; it's duty, breach, causation, and damages — and the professor has usually made only one or two of them genuinely arguable.

Issue-spotting is what actually separates grades, and it happens before you write a word. Strong exam-takers read the fact pattern twice: once to understand the story, once with the rule structure in mind, flagging every fact that triggers an element or an exception. A fact placed in a hypo on purpose is almost always doing legal work — the wet floor, the 'I was joking,' the two-day delay. If a fact doesn't map to a rule, ask why the professor included it. Missed issues score zero no matter how polished your writing; this is why allocating the first few minutes to a margin issue-list outscores diving straight into prose.

Allocate words by where the points are. The Rule should be tight — state it correctly and move on; you don't get extra credit for a paragraph of black-letter law. The Application is where the rubric concentrates its points, so it should be the longest section and should argue both sides of every genuinely contested element. A useful discipline under time pressure: budget your minutes per issue in proportion to how many elements are actually in dispute, and write the Application for the closest calls first, since that's where partial credit is densest.

Issue-spotting is a skill you practice, not a talent you either have or lack. The best training is working through past exams for the specific course with a professor's model answer in hand, then comparing your issue list to theirs. You will quickly find your personal pattern — most students consistently miss the same category of issue, whether that's defenses, procedural prerequisites, or issues buried in the last paragraph of the fact pattern. Identifying your blind spots and drilling against them is more efficient than writing unguided practice answers, because each targeted repetition fixes a specific gap.

The CRAC variation — Conclusion, Rule, Application, Conclusion — puts a one-sentence answer at the top, before the analysis. This is common in legal writing courses and professional memos because readers want the bottom line first. On exams, whether IRAC or CRAC is preferred depends on the professor; some reward leading with a tentative answer, others want you to build toward it. When in doubt, use standard IRAC — it is never wrong. If you use CRAC, keep the opening conclusion short and hedged ('Probably liable for negligence') and move immediately to the Rule; the opening conclusion is not a substitute for analysis.

A practical pre-writing system for IRAC under time pressure: (1) Read the call of the question first — 'Discuss Alex's potential liability' tells you the scope before you read the facts. (2) Read the facts once for story, once for legal triggers. (3) List every issue, grouped by claim. (4) Rank them by how much is genuinely in dispute — contested elements get full IRAC, clear elements get one sentence. (5) Write in issue order, not fact order. This sequence keeps the answer organized even when the fact pattern is designed to confuse and prevents the most common exam failure: writing beautifully about the wrong things.

The Rule section is where precision pays off. A vague rule — 'negligence requires a breach of duty that causes harm' — is technically not wrong but earns partial credit because it omits the elements the professor will check against. A complete rule names the test, its elements, and where they come from: 'A defendant is liable for negligence if they owed a duty of reasonable care to a foreseeable plaintiff, breached that duty by falling below the reasonable person standard, and the breach was both the but-for and proximate cause of a cognizable harm.' That sentence is a checklist. The professor reads it and sees that you know the doctrine precisely enough to walk each element, which is what earns full points before you've written a word of Application.

Knowing which issues to give full IRAC and which to dispatch in a sentence is the efficiency skill that separates B+ answers from A answers under time pressure. An issue deserves a full IRAC — including a counterargument — when there is a genuine argument on both sides given the specific facts in the problem. An issue deserves one sentence when it is clear: 'Duty is undisputed — the defendant owned the premises and owed a duty of care to all invitees.' Professors do not reward lengthy analysis of uncontested elements; they reward recognizing the close call and unpacking it. Train yourself to decide, before you write, whether each element is clear, close, or unclear — and allocate your words accordingly. This three-tier sorting, done in your issue list before you begin writing, is what keeps your answer from spending two paragraphs on something no one disputes and three sentences on the element the whole exam hinges on.

Use the Application to do real legal work on both sides, not to pick a winner immediately. The structure that earns the most points is: state the best argument for the plaintiff/prosecutor, state the best counterargument for the defendant, then explain why one side is stronger and why. 'Here, the defendant failed to post a warning sign (plaintiff's argument). Defendant may contend ten minutes was too short to respond (defendant's argument). However, the better view is that actual notice of a specific, fixable hazard requires immediate action, not a wait-and-see approach (resolution with reasoning).' That three-part structure — argue, counter, resolve — applied to each contested element is what a high-scoring Application looks like.

Annotated example — Contract formation hypo

A short contracts hypo answered in IRAC. Each section is numbered and annotated below.

Worked example

HYPO: Dana offers to sell her car for $5,000. Pat says, "I'll
think about it." Two days later, Pat calls and says, "I accept."
Dana has already sold the car to someone else.

① ISSUE
   Whether Pat's two-day delayed response constitutes a valid
   acceptance that formed a binding contract with Dana.

② RULE
   A valid contract requires offer, acceptance, and consideration.
   An acceptance must be unequivocal and communicated while the
   offer is still open. An offer lapses after a reasonable time
   or when circumstances indicate it is no longer available.

③ APPLICATION
   Dana made a clear offer: sell the car for $5,000. The
   threshold question is whether Pat accepted it. When Pat
   said "I'll think about it," that was not an acceptance —
   it was a conditional non-answer that left the offer open.

   By the time Pat called two days later to say "I accept,"
   the relevant question is whether the offer was still open.
   Dana had already sold the car, which signals the offer had
   lapsed. Even without that fact, a two-day silence without
   communication may itself be an unreasonable delay depending
   on the context of the transaction.

   Pat could argue the offer was still technically open because
   Dana never expressly revoked it. But the better argument is
   that Dana's disposition of the car constitutes an implied
   revocation, and a reasonable person in Pat's position would
   not believe the offer remained available after learning this.

④ CONCLUSION
   No contract was formed. Pat never accepted while the offer
   was open, and by the time he did, the offer had lapsed.
1

Issue — specific, not generic

Notice it doesn't say 'Whether there was a contract.' It identifies the specific disputed element (acceptance) and the specific disputed fact (two-day delay). The more precise your Issue, the clearer the roadmap for your Application.

2

Rule — general and reusable

The Rule doesn't mention Dana or Pat. It states the law of offer and acceptance in a form that would apply to any contract case. If you find yourself writing 'In this case' in your Rule section, you've drifted into Application.

3

Application — the longest section by design

This is where the grade lives. Notice it works element by element, uses the specific names and facts from the hypo, argues both sides (Pat's counterargument is addressed), and uses reasoning rather than just assertion. 'A reasonable person would not believe...' is a legal conclusion supported by a reason.

4

Conclusion — one or two sentences, no new reasoning

It answers the exact question posed in the Issue. 'No contract was formed' answers 'Whether Pat formed a binding contract.' It adds the key reason but doesn't introduce anything new. If your Conclusion is three sentences of new analysis, move that material to Application.

Common mistakes

1

Issue is too vague

'Whether negligence occurred' is not an Issue — it's a category. A precise Issue names the specific element in dispute and ties it to the facts: 'Whether the defendant breached the duty of care when she failed to post a wet-floor warning sign despite knowing the floor was slippery.' Vague issues produce vague analysis.

2

Rule is fact-specific

If your Rule only works for the specific fact pattern in front of you, it's not a rule — it's a holding. The rule should be applicable to any case with similar legal issues. Test it: could you copy this sentence into a different case's brief and have it still be true?

3

Application doesn't use the facts

Restating the rule is not application. 'The defendant must have breached a duty of care. Breach requires falling below the reasonable person standard.' That's just the Rule again. Application means using the specific facts as evidence: 'Here, leaving a wet floor unmarked for two hours despite three customer complaints establishes that defendant fell below the reasonable person standard because...'

4

Conclusion introduces new analysis

If your Conclusion paragraph contains reasoning you haven't already made in Application — a new fact, a new rule, a new argument — that reasoning belongs in Application. The Conclusion is a verdict, not a closing argument.

5

Only arguing one side

An Application that marches straight to the answer leaves points on the table. Exam fact patterns are built to be close — the professor wants to see you argue the defendant's best counterargument and then explain why one side is stronger. 'Pat could argue X, but the better view is Y because Z' earns more than a confident one-sided conclusion.

6

Spotting one issue and stopping

The fastest way to lose points you could have earned is to find the obvious issue, write a beautiful IRAC on it, and miss the two smaller issues buried in the same facts. Run a quick element checklist for every claim before you start writing, and give each contested element its own mini-IRAC.
