An Automated Test Assembly Approach Using Item Response Theory to Enhance Evidence of Measurement Invariance
When creating a new test to measure a latent trait, test developers must select items that together demonstrate desirable psychometric properties. Automated test assembly (ATA) algorithms allow test developers to systematically compare possible item combinations based on the test’s goals. ATA …

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 …

Evaluation of the Safety Systems in the Next Generation Boiling Water Reactor
… in the Purdue university multi-dimensional test assembly (PUMA). RELAP5 code simulations, both for the PUMA main steam line break (MSLB) case and for the simplified boiling water reactor (SBWR) MSLB case have been utilized to compare with the experiment data. The comparison shows that RELAP5 …

On-the-fly assembled multistage adaptive testing
Computer-administered tests such as the computerized adaptive test (CAT) and multistage tests (MST) have been widely implemented in many large scale tests. In 2000, some testing organizations uncovered some pitfalls of CAT after it was applied to large scale testing. After these instances, many …

A test method for smolder resistance of upholstered furniture
The purpose of this research was to find a test method and a fabric classification procedure which would reliably indicate whether fabrics could perform in a fire safe manner when tested on a modification of the National Bureau of Standards (NBS) test assembly. The NBS upholstered furniture fabric …
