How to Write an Exam: A Step-by-Step Guide for Teachers and Instructors

A badly written exam doesn't just produce unfair grades: it teaches students to study badly. If you always ask for textbook definitions, they'll learn to memorize definitions. If the multiple-choice section can be passed by elimination, they'll learn to eliminate. The exam is the clearest message you send about what matters in your course.

This guide is for people who write exams regularly: college instructors, test-prep and certification trainers, and high school teachers. It's not about assessment theory, but about the concrete steps from "I have to set an exam for Thursday" to an exam that measures what you want it to measure.

1. Start with what students must be able to do

Before writing a single question, write down in three or four sentences what the student has to demonstrate. Not "chapter 5", but:

• Distinguish between the main types of contracts and their requirements.
• Apply straight-line depreciation to a case.
• Argue the causes of a historical event.

Each sentence starts with a verb, and the verb decides the question type. "Identify" or "recognize" are measured well with multiple choice. "Apply" calls for a problem or a case study. "Argue" or "compare" call for an essay. If your exam only has recognition questions, you're only measuring memory, whatever your objectives say.

For certification or licensing prep, this step is already done: the official exam format rules. If the real exam is 100 multiple-choice questions plus a case study, your practice exams have to look like that, not like what's convenient for you to grade.

2. Build a test blueprint

It's the most useful tool and the least used. A simple table with topics in rows and task types in columns, and in each cell how many questions or points:

It forces you to decide the weight of each topic before writing, instead of finding out at the end that your favorite unit takes up half the exam. And it leaves you a template for the next exam and for version B.

3. Choose the mix of question types

Each format measures different things and costs different effort, for you and for the student:

• Multiple choice: covers a lot of material quickly and grades fast. It's hard to write well: weak distractors make it passable without knowing. We cover it in depth in how to write multiple-choice questions that can't be guessed.
• True/false: quick, but with a 50% chance of guessing right. Use it to check isolated concepts, not as the backbone.
• Short answer: forces recall without cues. A good balance between coverage and depth, and reasonably quick to grade.
• Essay: measures structure, connections between ideas and argument. Covers little material and is the slowest to grade, so use few, well-chosen questions.
• Problems and case studies: the only real measure of "apply". Essential in quantitative subjects and professional exams.

A common mix in college: a multiple-choice or short-answer block to cover the material, plus one or two essay questions or a case study for what really matters.

4. Grade the difficulty

An exam with only hard questions doesn't discriminate: almost everyone fails and you can't tell who knew more. All easy questions, same problem in reverse. As a reference:

• A third accessible: what anyone who studied should know.
• Half medium difficulty: what separates those who studied from those who studied well.
• One or two demanding questions: the ones that identify the top students.

Order them from easier to harder within each block. Starting with an approachable question reduces freezing and gives you more reliable grades.

5. Estimate time realistically

The classic mistake is setting an exam you'd finish in 30 minutes and allowing 60, thinking that's double. A student takes three to four times as long as the person who wrote it. Rough references:

• Multiple choice or true/false: about 45–60 seconds per question.
• Short answer: 2–3 minutes.
• Essay: 15–25 minutes per question, depending on the length you ask for.
• Problem or case study: your own time, times three.

If the exam doesn't fit the time, don't accidentally measure speed: cut questions.

6. Write instructions that leave no doubt

Questions during the exam waste time and create unfairness. Instructions should state:

• How much each question or section is worth.
• Whether wrong multiple-choice answers are penalized, and by how much.
• Expected length for open questions ("about 10 lines", "one page").
• Whether spelling counts and how.
• What materials, if any, are allowed.

7. Write the answer key and rubric before printing

Writing the model answer to every question before you set the exam is the best quality check there is. If you can't write a clear answer in two lines, the question is badly framed.

For open questions, define the criteria: which ideas must appear, how much each is worth, and what counts as a partial answer. You'll grade faster, with less drift between the first exam and the thirtieth, and you'll be able to justify each grade when students ask.

8. Review before printing

Ten minutes of review saves an hour of grade disputes. Check that:

• No question gives away the answer to another.
• No two questions ask the same thing in different words.
• Stems have no double negatives or ambiguity ("which is not incorrect?").
• In multiple choice, the right answer isn't always in the same position.
• Figures and dates are correct.

If you can, ask a colleague to take it without the answer key. Whatever makes them hesitate will make your students hesitate.

9. Make a version A and a version B

With large groups or tight rooms, two versions reduce the temptation to look at a neighbor's paper. There are two ways:

• Same questions, different order: quick, but it only works for multiple choice and students can still recognize the question.
• Different questions on the same blueprint: more work, but the only fair way. Both versions have the same weight per topic and the same task types, even though the questions differ.

This is where the blueprint from step 2 pays back the time you put into it.

Where AI helps (and where it doesn't)

Drafting twenty multiple-choice questions with good distractors, or a second version of the same exam, is mechanical work that comes from material you already have. That's what an AI tool does best.

In ExamFlow you upload your course material (PDF, Word or photos) and generate an exam on the topics you choose: multiple choice, true/false, short answer or essay, with a theory or practice focus, easy, medium or hard difficulty, the number of questions and, optionally, a time limit. For a version B, you generate another set on the same topics. Each exam can be printed blank or downloaded as a PDF, with space for name, date and grade. More on this in ExamFlow for teachers.

What AI doesn't do is decide what matters in your course or replace your review. Steps 1, 2 and 8 are still yours: the draft takes a minute, but the judgment is yours.
