How to Write True or False Questions (With Examples)

Introduction

True or false questions look like the easiest thing in the world to write. One sentence, two possible answers, done. But anyone who has taken a badly written true/false test knows the problem: you can often guess the answer from the wording alone. A good true/false question tests what someone knows. A bad one tests how well they read test-writers' habits.

This guide shows you how to make true or false questions that are fair, clear and actually useful, with good and bad examples for each rule and a template you can copy.

When true/false questions are the right choice

They're weaker for testing complex reasoning, and a student has a 50% chance of guessing right. So use them alongside other formats such as multiple choice, fill-in-the-blank and short answer, not instead of them.

• Quick checks of facts such as dates, definitions and cause and effect.
• Surfacing misconceptions. A false statement built around a common mistake shows instantly who still believes it.
• Warm-ups and reading checks. Students can answer ten in a couple of minutes.

8 rules for writing good true or false questions

1. Test one idea per statement. If a statement contains two claims, one might be true and the other false, and the student can't answer honestly. ❌ The heart has four chambers and pumps blood only to the lungs. ✅ The human heart has four chambers. (True) ✅ The right ventricle pumps blood to the lungs. (True)

2. Avoid absolute and hedge words that give it away. "Always", "never", "all" and "none" are usually false; "often", "usually" and "may" are usually true. Test-savvy students know this. ❌ Metals are always solid at room temperature. (Students guess "false" from "always".) ✅ Mercury is a metal that is liquid at room temperature. (True)

3. Make the false statements plausible. A false statement should be wrong in one meaningful way: a changed number, a swapped cause, a reversed direction. It shouldn't be absurd. ❌ World War II ended in 1066. ✅ World War II ended in 1918. (False. That's WWI; it tests whether students mix up the two.)

4. Don't use double negatives. ❌ It is not true that plants do not need sunlight. ✅ Plants need light to carry out photosynthesis. (True)

5. Keep true and false items a similar length. Writers tend to add qualifiers to make true statements precise, so long statements end up true more often. Watch for it.

6. Base each statement on the material, not trivia. Ask: "Would understanding this lesson help someone answer this?" If the answer depends on a footnote or a trick of phrasing, rewrite it.

7. Balance the answer key. Aim for roughly half true and half false, in no predictable pattern (not T, F, T, F…).

8. Add a one-line explanation. "False: oxygen is a product, not a reactant" turns a mark into a lesson. This matters most in self-study.

A true and false quiz template you can copy

Title: __________________ Class/Topic: __________ Date: ______

Directions: Write T if the statement is true and F if it is false.

1. ______________________________________ ___

2. ______________________________________ ___

3. ______________________________________ ___

Answer key + explanations

1. __ because ____________________________

2. __ because ____________________________

Variation: "correct the false ones." Ask students to rewrite every false statement so it becomes true. This removes the 50% guessing advantage and checks real understanding.

Worked example: from notes to questions

Say your notes read: "The water cycle is driven by the sun. Water evaporates from oceans, condenses into clouds, and falls as precipitation. Transpiration from plants also adds water vapor to the air."

Statements you could write:

1. The sun provides the energy that drives the water cycle. (T)

2. Condensation is the process of water vapor turning into liquid droplets. (T)

3. Precipitation is how water vapor enters the atmosphere. (F: that's evaporation and transpiration.)

4. Plants add water vapor to the air through transpiration. (T)

5. Clouds form when liquid water evaporates directly into ice crystals. (F: clouds form through condensation.)

Notice each one tests a single idea from the notes, and the false ones swap a real term for a related but wrong one.

How to make true or false questions faster with AI

Writing twenty balanced, well-worded statements by hand takes a while. An AI tool can do the first draft for you. With Examina's true or false quiz generator, you paste notes (or upload a PDF, TXT or Markdown file) and get true/false questions with the correct answer and an explanation for each. Every question is tagged with a Bloom's taxonomy level, so you can tell recall items from understanding items.

Whatever tool you use, run its output through the 8 rules above. They work just as well as an editing checklist.
