Item Analysis. Item Analysis is an important (probably the most important) tool to increase test effectiveness. Each items contribution is analyzed and assessed. To write effective items, it is necessary to examine whether they are measuring the fact, idea, or concept for which they were intended.
When norm-referenced tests are developed for instructional purposes, to assess the effects of educational programs, or for educational research purposes, it can be very important to conduct item and test analyses. These analyses evaluate the quality of the items and of the test as a whole. Such analyses can also be employed to revise and improve both items and the test as a whole. However, some best practices in item and test analysis are too infrequently used in actual practice.
