What is an objective of using various test item formats?

Using various test item formats is important because it allows for a broader assessment of different skills and knowledge. Different types of questions can evaluate various cognitive processes and learning outcomes. For instance, multiple-choice questions can effectively assess recognition and recall, while essay questions might better evaluate critical thinking or the ability to articulate ideas clearly. By incorporating a range of formats, instructors can capture a more comprehensive picture of a student's understanding and mastery of the material. This diversity in assessment formats ultimately leads to a more effective measurement of a student's capabilities across different contexts and subject areas.
