Computerized Adaptive Testing: A Primer

Computerized Adaptive Testing (CAT) is now entering a new phase of its existence, having developed into a viable alternative form of measurement backed by rigorous technology involving far more than hardware and software. Computer technology, test development, statistics, and mental test theory all play a role in CAT and are thus united in this primer. Based on 30 years of solid research, this book will educate the novice and serve as a compendium of state-of-the-art data for professionals. A hypothetical test taken as a prelude to employment, the "Gedanken Computerized Adaptive Test," is used throughout as a common example that highlights important features and problems presented by different types of computerized testing.
