The effectiveness of using multiple item pools to increase test security in computerized adaptive testing
… pool usage balance for Computerized Adaptive Testing (CAT). Also, the extent to that multiple item pools can reduce 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 …

Advancements in test security: preventive test assembly methods and change-point detection of compromised items in adaptive testing
Chapter 1: Test security is as longstanding as testing itself. The broad issues are introduced very briefly, then the specific matters pertaining to computerized adaptive testing (CAT) are discussed. The framework of CAT is established in detail, then the vital security concerns of item exposure …

Test coaching on assessments of cognitive constructs
In continuously administered employment tests, test security may be compromised by examinees revealing test items to future test candidates. Unlike academic testing, employee selection tests generally have longer test windows and are less likely to implement new test items or have multiple parallel …

Computerized Adaptive Testing---New Developments and Applications
Computerized adaptive testing (CAT) has become a very important testing mode since it was introduced into the testing field in the early 1970's. It has clear advantages over the traditional paper-pencil testing in many aspects including shorter tests and more efficient score reporting. However, it …

Effect of Sample Size on Irt Equating of Uni-Dimensional Tests in Common Item Non-Equivalent Group Design: a Monte Carlo Simulation Study
Test equating is important to large-scale testing programs because of the following two reasons: strict test security is a key concern for high-stakes tests and fairness of test equating is important for test takers. The question of adequacy of sample size often arises in test equating. However, …

An Investigation of Answer Changing on a Large-Scale Computer-Based Educational Assessment
Answer changing on tests has been studied for decades, however more recently answer-changing analysis has risen as an approach for exploring potential test fraud on high-stakes achievement tests. The purpose of this study was to document answer-changing patterns of students grades 3-11 on …
