Explore the moving sample size used in a procedure for detecting compromised items based on item response theory
… can provide tests for examinees continuously, so items in the item bank face the risk of being leaked. The IRT-based detection procedure developed by Zhang and Li (2016) is further studied in this thesis, which is designed to identify compromised items via a series of hypothesis tests. The moving …

Advancements in test security: preventive test assembly methods and change-point detection of compromised items in adaptive testing
… not only be assessed in terms of the number of items administered but also the time it takes to complete the test. To this end, a recent study introduced a novel item selection criterion that maximizes Fisher information per unit of expected response time, which was shown to effectively reduce …

The effectiveness of using multiple item pools to increase test security in computerized adaptive testing
… the bias of CAT in the presence of possibly compromised items will be explored. Item selection algorithms were designed using three conditions: item pool configuration (single item pool, two item pools, and three item pools), item selection method (the random item selection method, the …
