How to write multiple choice questions well
By Votense · Published 2026-10-11 · Updated 2026-10-11
A multiple choice question has three parts: a stem that asks the question, one correct answer, and several wrong answers called distractors. Good items test one idea, use wrong answers that look reasonable to someone who has not learned the idea yet, and give a clear answer key. Most of the work is in the distractors, which is why a short question can take longer to write than a long one.
The University of Michigan Center for Research on Learning and Teaching notes that items usually have at least three incorrect options, and it recommends distractors built from common errors or misunderstandings about the concept. It also notes that recall and recognition are easier to test this way than higher-order thinking, so you may need other formats for analysis or design tasks.
The four steps
- Start from one learning outcome. Write the stem to test one idea from the lesson. If you cannot say which idea it tests, the question is not ready.
- Write the stem so it stands alone. A reader should know what is being asked before they see the options. Avoid negatives and double negatives.
- Write the correct answer first, then the distractors. Build each wrong answer from a real mistake: a sign error, a common misconception, or the answer to a neighbouring question.
- Check the key. Put the correct answer in a different position each time, make all options similar in length and style, and have a colleague answer the question without seeing the key.
Worked example: a weak question and a better one
A weak version: “Which is the largest planet? A) Jupiter B) Mars C) Pluto D) All of the above.” The correct answer is obvious, two options are silly, and “all of the above” gives the answer away to anyone who spots that Jupiter is in the list.
A better version: “Which planet is the largest in the Solar System? A) Saturn B) Jupiter C) Neptune D) Earth.” Each wrong option is a real planet, and Saturn is a common mix-up because it is the second largest. The stem is a single question, and the answer key is clear.
Good and poor distractors
| Poor distractor | Why it fails | Better distractor |
|---|---|---|
| A silly answer, such as “a banana” | Students rule it out at once, so the question tests nothing | A plausible wrong answer from a real mistake |
| “All of the above” | Lets a student guess from two correct options | A fourth realistic option |
| A much longer correct answer | The right answer stands out by its length | Matching length and wording for every option |
| A wrong answer that repeats the stem | Gives a clue to the answer | An option that uses the same words but a different idea |
Turning the questions into a quiz
Once the questions are written, put them in a quiz so people can answer them. The quiz maker takes choice questions with two to six options and a correct mark. You can host the quiz live with a PIN or share a link, and you can add an explanation to each question. If the quiz is graded, the exam maker adds a timer, a pass mark and grade bands.
Results show which question caught the most people out. Treat a question that most people missed as a prompt to check your teaching first, and only then the question. Sometimes a question that most people miss has two defensible answers, and the fix is to rewrite the stem.
Where multiple choice fits
Multiple choice is strong for checking recall and recognition across many topics quickly. It is weaker for showing how a student reasons. Pair it with short written answers or practical tasks when you need evidence of analysis. For how to match question levels to the skill you are testing, see the Bloom’s taxonomy question stems guide, and for the broader purpose of each assessment, see formative vs summative assessment.

Frequently asked questions
How many answer options should a multiple choice question have?
At least three incorrect options and one correct answer is the usual minimum in teaching-centre guidance, such as the University of Michigan’s CRLT. Votense quizzes accept two to six options per question, so choose the number that gives enough plausible wrong answers without padding.
Should I use “all of the above” or “none of the above”?
Generally no. Guidance from teaching centres discourages both. “All of the above” lets a student who recognises two correct answers guess, and “none of the above” hides whether the student knows the right answer.
Can a quiz show an explanation after the answer?
Yes. Each Votense quiz question can carry an explanation that appears after the reveal, both in a live game and when a player takes the quiz from a link, so the wrong answers become a short lesson.
