Estimating Testing Time: The Effects of Item Characteristics on Response Latency.
Halkitis, Perry N.; And Others
The relationship between test item characteristics and testing time was studied for a computer-administered licensing examination. One objective of the study was to develop a model to predict testing time on the basis of known item characteristics. Response latencies (i.e., the amount of time taken by examinees to read, review, and answer items) were obtained from 197 individuals taking a national licensing examination for real estate appraisers for the first time. Response latencies were measured by the computer during the test taking process. Results of the study, which parallel results from paper-and-pencil tests, indicate that item response time was determined by three item characteristics: (1) item difficulty; (2) item discrimination; and (3) word count. These variables accounted for about half the variance in the response time. Item position, however, seems to have an inverse effect on response time, indicating that less time is required as one progresses through the examination. This may be due to the effect of practice as the examinee gains more experience with computer testing or with test speededness. Results provide a temporary model that test developers can use in estimating the amount of time that should be allotted to computer-administered examinations.
