Item selection methods with exposure and time control for computerized classification test.

Computerized classification testing (CCT) commonly chooses items maximizing information at the cut score, which yields the most information for decision‐making. However, a corollary problem is that all examinees will be given the same set of items, resulting in high test overlap rate and unbalanced item bank usage, which threatens test security. Moreover, another pivotal issue for CCT is time control. Since both the extremely long response time (RT) and large RT variability across examinees intensify time‐induced anxiety, it is crucial to reduce the number of examinees exceeding the time limitation and the differences between examinees' test‐taking times. To satisfy these practical needs, this paper proposes the novel idea of stage adaptiveness to tailor the item selection process to the decision‐making requirement in each step and generate fresh insight into the existing response time selection method. Results indicate that a balanced item usage as well as short and stable test times across examinees can be achieved via the new methods. [ABSTRACT FROM AUTHOR]
