The main advantage of selection-type test items, such as multiple-choice questions, lies in their objectivity in grading. When using these types of questions, responses can be evaluated in a standardized manner, ensuring that the grading is not influenced by the individual perspectives or biases of the learner or the instructor. This objectivity benefits both the assessment process and the learners, as it helps to minimize discrepancies that could arise from subjective interpretations of open-ended responses.

Selection-type tests allow for straightforward scoring, typically with answer keys that clearly indicate correct responses. This makes it easier for educators to assess a large number of students efficiently, maintaining a level of fairness and consistency in grading across different learners. Therefore, the reliability of assessments is enhanced with the use of selection-type items, particularly in large classes or varied instructional settings.
