How to Use the LSAT Logical Reasoning Item Writer Prompt to Build Original Practice Sets for Students
Write original LSAT style Logical Reasoning practice items for a tutoring program: a short argument stimulus, a stem from the right question family, one defensible credited answer, four wrong answers built on named traps such as too strong, reversal, and out of scope, a planned difficulty level, and a teaching explanation for every choice.

Logical Reasoning makes up most of the scored LSAT, and students who struggle usually struggle with specific patterns: picking answers that are too strong on assumption questions, missing sampling flaws, or confusing a reversal with a valid inference. Tutors can assign released tests, but they run out fast, and they rarely target one weakness at a time. The LSAT Logical Reasoning Practice Item Writer for Tutors: Original Stimulus Arguments, Question Stem Families from Flaw to Parallel Reasoning, Five Answer Choices with Named Distractor Traps, Difficulty Levers, and Explanations prompt helps tutors and prep course writers create original practice items aimed at exactly the skills a student needs, complete with named distractor traps and explanations for every answer choice.
What the prompt produces
- An item map listing each item's question family, topic, difficulty, and the reasoning pattern it tests.
- Original stimulus arguments of 50 to 110 words in a neutral, test like register.
- Question stems worded the way each family is normally asked, including EXCEPT and principle versions.
- Five answer choices with one defensible credited answer and four distractors, each built on a named trap.
- Difficulty levers that explain what makes each item easy, medium, or hard.
- Explanations for every choice, so students learn why wrong answers are wrong.
- A tutor note per item tied to the student's weakness.
- A quality check table confirming one credited answer, no outside knowledge needed, and balanced answer positions.
How to fill the inputs
QuestionFamilies lists the types you want, such as flaw, necessary assumption, strengthen, weaken, parallel reasoning, or resolve the paradox. Mixing two or three families per set keeps students from guessing the task from the topic.
ItemPlan gives the number of items and the difficulty of each. Start with medium items for a new student and add hard ones once they are consistent.
TopicAreas sets the subjects to rotate. Real tests cover science, law, business, the arts, and policy, so rotating topics helps students focus on structure instead of content.
StudentProfile is where the targeting happens. Describe the traps the student keeps falling for. The prompt builds distractors that test those exact habits.
Reading the example output
The example asks for two items: a medium flaw question and a hard necessary assumption question, for a student who picks too strong answers and misses sampling flaws.
- The flaw item is a sampling problem. A council member surveys riders at downtown express stops and draws a conclusion about the whole bus system.
- The assumption item uses competing causes. A marine biologist blames sea urchins rather than warmer water for kelp loss, so the argument depends on warming not explaining most of the loss.
- Two distractors are deliberately too strong. Words like "never" and "only" appear in wrong answers because that is the student's known weakness.
- The explanations teach a method. The tutor note for the assumption item asks the student to run the negation test on each choice before picking.
- The quality check counts stimulus words and confirms no outside knowledge is required.
Tips for better results
- Review every credited answer yourself. If you can argue for two answers, rewrite the item.
- Keep stimulus topics neutral. Students should not be able to answer from opinion or background knowledge.
- Track which traps each student falls for across sessions and update StudentProfile.
- Time students on the generated sets once they are accurate, since pacing matters on test day.
- Mix generated items with official practice tests so students also see the real thing.
Mistakes to avoid
- Do not copy or paraphrase released LSAC questions. The prompt is built to write original items, and you should keep it that way.
- Do not label generated items as official questions.
- Do not write all hard items with obscure vocabulary. Real difficulty comes from structure and tempting distractors.
- Do not skip the explanations. They are where most of the learning happens.
Who it is for
LSAT tutors, test prep course writers, pre law advisors building practice materials, and self studying students who want targeted drills between full practice tests.
