Completion questions require a student to complete a statement that is missing one or more key elements (words, phrases, numbers, etc.). Similar to matching and true/false, completion questions are considered better for assessing lower levels of cognition, and are best to check whether key facts have been memorized. However, unlike these other question types, completion questions rely more heavily on recall than recognition. Thus, compared to forced-choice question types (e.g., multiple choice, true/false), the potential for guessing the correct answer is reduced. However, scoring completion items is difficult to automate, and thus marking can be time consuming relative to some question types.
