The proportion for the item is usually denoted as p and is called item difficulty (Crocker & Algina, 1986). An item answered correctly by 85% of the examinees would have an item difficulty, or p value, of .85, whereas an item answered correctly by 50% of the examinees would have a lower item difficulty, or p value, of .50. In doing so, item analysis can increase the efficacy of your exams by testing knowledge accurately. And knowing exactly what it is students know and what they don’t know, helps both student learning and instructor efficacy. SUGGESTIONS Instructional objectives should be kept in mind so as to achieve maximum content validity.

Students with an acute sense of understanding and knowledge can tick or circle the right answer.

An item that everyone gets correct or that everyone gets incorrect, as shown in Tables 1 and 2, will have a discrimination index equal to zero. Table 7 illustrates that if more students in the lower group get an item correct than in the upper group, the item will have a negative D value and is probably flawed. Test analysis examines how the test items perform as a set.

Looking at an item’s difficulty and discrimination will assist the test developer in determining what is wrong with individual items. Item and test analysis provide empirical data about how individual items and whole tests are performing in real test situations. In practical test construction, item analysis is an iterative process, and cannot be entirely automated. The psychometrician’s judgement is required to determine whether the emerging set of items to be retained constitutes a satisfactory test of the target construct. The three criteria above do not always agree, and a balance must be struck between them in deciding whether or not to include an item.
