Item Theft in a Continuous-Testing Environment: What Is the Extent of the Danger? Law School Admission Council Computerized Testing Report. LSAC Research Report Series.
Schnipke, Deborah L.; Scrams, David J.
This study explored the dangers of item theft in terms of impact on test quality and fairness. Simulations were used to explore the impact of item theft on test taker scores. In the simulation, a simulated, organized group of thieves took the test, memorized the items received, and distributed the items to future test takers. Impact was explored for varying numbers of thieves and for thieves of two ability levels. Results show that test takers scores can be largely inflated when test takers have prior knowledge of items. Who gets inflated scores depends on the test takers ability, and the number and difficulty of the stolen items. Although the results may be cause for caution, concerns raised by this study must be considered in the proper context. This study investigated one simple design with only one item pool. Other designs may provide more opportunities to counteract the threat of item theft. Possible solutions to the problem are discussed, and further research is planned to evaluate these possibilities.
