True-false questions require students to judge whether statements are true or false. Guidelines for constructing true-false questions include using clear, unambiguous statements and avoiding clues that may give away the answer. True-false questions can reliably and efficiently measure a wide variety of learning outcomes and are well-suited for questions with only two possible answers or testing for common misconceptions. Examples demonstrate good true-false questions are concise and avoid unnecessary details, while poor questions contain unnecessary information or negatives that make the statement hard to judge.
