Eli Item-Writing Academy
About 40 minutes · Academy module: Foundations of MBE Item Writing.
Every MBE-style item has the same anatomy: the fact pattern (the scenario), the call of the question (the actual question being asked), the key (the one best answer), and the distractors (the wrong options). The fact pattern sets the legal context, the call states the decision, the key rewards the right reasoning, and the distractors do the discriminating.
The most common beginner error is writing the fact pattern first and discovering the question at the end — which produces items with no call at all (see this module's drill). A disciplined order prevents that: tested point, then key, then distractors, then the fact pattern that lets a prepared examinee converge on the key.
Before you write a single word of fact pattern, state the tested point as a complete sentence: "Under the mailbox rule, the offeree's acceptance is effective on dispatch, so the contract formed Tuesday when the acceptance was mailed — the revocation mailed Wednesday was effective only on receipt, too late." That sentence is your compass. Every fact you add should point toward it or rule out a near-miss; everything else is noise.
Our read: faculty who skip this step produce items where the "best" answer is debatable — because the author never decided what, precisely, was being tested. Two independent cold solvers disagreeing on your key is almost always a symptom of an unstated tested point, not a hard item.
With the options hidden, the examinee should know exactly what is being asked and be able to generate the answer's shape. If the call is "which of the following is correct," the item is unfocused — finish the question before you write the options. A focused call names the decision: "Is there a contract?", "How should the court rule on the motion?", "Which statement correctly describes the parties' rights?"
The cover test also catches stems that ask two questions at once. If covering the options leaves the examinee wondering whether you want the jurisdictional answer or the merits answer, split the item in two or commit to one.
Options should be the same kind of phrase, similar in length, and at the same level of specificity. Four holdings, not three holdings and a rationale. Four "yes/no, because" pairs, not three pairs and a bare conclusion. When one option is conspicuously longer, more detailed, or grammatically different, test-wise examinees use the difference as a clue — that is cueing, and it is the Flaw Clinic's whole subject.
Plausibility is the other half: every distractor must be an answer a partially-prepared examinee could genuinely choose. An option nobody would pick does not discriminate; it decorates. Draw distractors from the same doctrinal family as the key — other acceptance-timing rules when the key is the mailbox rule, other hearsay exceptions when the key is excited utterance — so the examinee must actually know the doctrine to choose.
An item should test one decision. If the fact pattern mixes a contracts formation issue, a torts negligence issue, and an evidence hearsay issue, and the options span all three, the item tests everything and measures nothing. Strip the pattern to what the tested point needs: the facts that point toward the key and the facts that rule out the best near-miss. Every extra sentence is either a clue (rewarding word-matching) or noise (punishing careful readers).
(intended key: C)
Fact pattern: A seller emails a buyer: "Will sell you my boat for $20,000. Reply by Friday." The buyer replies Thursday: "I'll take it for $18,000." The seller does not respond. Friday passes.
A. There is a contract for $20,000 B. The seller's email was an invitation to negotiate C. There is no contract D. The buyer accepted by email
unfocused stem — no call of the question.
There is no question here, so there is nothing to answer; each option belongs to a different kind of legal conclusion. An unfocused stem turns the item into a guessing game about what the author wanted. The rewrite supplies a call that names the decision — "is there an enforceable contract, and why" — and rebuilds the options as parallel holdings with reasons, so the item tests formation doctrine instead of mind-reading.
— cold-solve verified: 2/2 (solvers chose C, C)
Fact pattern: A seller emails a buyer: "Will sell you my boat for $20,000. Reply by Friday." The buyer replies Thursday: "I'll take it for $18,000." The seller does not respond. Friday passes. The seller sues for breach. Is there an enforceable contract?
A. Yes, because the buyer's Thursday reply was an acceptance B. Yes, because the seller's email was a firm offer C. No, because the buyer's reply was a counteroffer that terminated the original offer D. No, because contracts for the sale of goods must be in writing
Key: C
A reply varying the price is a counteroffer, not an acceptance, and it terminates the original offer; the Friday deadline then lapsed with no acceptance. Both independent cold solvers selected C and named no other defensible option.
