Computerized Adaptive Testing: From Concept to Implementation

Used worldwide in assessment and professional certification contexts, computerized
adaptive testing (CAT) offers a powerful means to measure individual differences or
make classifications. This authoritative work from CAT pioneer David J. Weiss and Alper
Sahin provides a complete how-to guide for planning and implementing an effective
CAT to create a test unique to each person in real time. The book reviews the history of
CAT and the basics of item response theory used in CAT. It walks the reader through
developing an item bank, pretesting and linking items, selecting required CAT options,
and using simulations to design a CAT. Available software for CAT delivery is described,
including links to free and commercial options. Engaging multidisciplinary examples
illustrate applications of CAT for measuring ability, achievement, proficiency,
personality, attitudes, perceptions, patients’ reports of their symptoms, and academic
or clinical progress.

•CAT offers effective means to measure ability, achievement, proficiency, personality,
attitudes, and patient-reported symptoms.
•Using AI and machine learning, CAT is personalized in real time for each examinee,
resulting in shorter testing times, more precise scores, and lower costs.
•Widely used in schools, higher education admissions, health care, professional
certification and licensure, employment screening, and military placements.
•Weiss–– considered the father of CAT–– provides an authoritative, accessible guide to
setting up a CAT program from scratch.
•Will be of particular interest in the U.S., U.K., Germany, the Netherlands, UAE, Saudi
Arabia, Turkey, Singapore, and Brazil.
