What must instructors ensure about the wording of one test item?

For a test item to be effective, it is essential that it does not inadvertently give away the answer to another item. This ensures that each question stands on its own and assesses the specific knowledge or skills that it is intended to evaluate. When test items are carefully constructed in this way, it helps to maintain the integrity of the assessment and allows for a more accurate measurement of a student's understanding. If one question hints at the answer to another, it can lead to confusion, skewed results, and may not truly reflect a student's grasp of the material. The clarity and independence of each item are critical for a fair and valid assessment process.
