Educational Measurement and Evaluation

Notes • In addition to examining the performance of an entire test item, teachers are also interested
in examining the performance of individual distractors (incorrect answer options) on
multiple-choice items. By calculating the proportion of students who chose each answer
option, teachers can identify which distractors are “working” and appear attractive to
students who do not know the correct answer, and which distractors are simply taking up
space and not being chosen by many students.
