Item Banks: What, Where, Why and How.
Anzaldua, Ric M.
This paper discusses item banks calibrated to indicate levels of difficulty to assist in test development. The item bank topics discussed are: (1) purpose; (2) development issues; (3) advantages and disadvantages; and (4) practical issues. The most common issues are content validity, reliability, concerns with software purchase and programming, classification and analysis of items, maintenance and upkeep, and good item writing practice. It is important to remember that item response theory remains an integral part of interpreting ability measurements for the forms generated from the item bank. The paper cites examples of studies in which form linking and sample size have become issues. The calculations involved in linking forms are simple and straightforward, but when there are hundreds of items across a multitude of forms administered to thousands of examinees, linking forms becomes a massive undertaking. It is beneficial to take advantage of existing item bank software to develop an item bank. An example of linking forms is presented using a heuristic data set. (Contains 3 tables, 3 figures, and 18 references.) (SLD)
