Journal of Computerized Adaptive Testing

About the Journal

JCAT is a peer-reviewed electronic journal designed to advance the science and practice of computerized adaptive testing (CAT). JCAT publishes two types of manuscripts:

  1. Empirical research reports, theoretical papers, and integrative critical reviews on topics directly related to CAT (e.g., item selection algorithms, security algorithms, multistage designs, examinee reactions to CAT, DIF in CAT, item bank development, the psychometrics of CAT) and on important ancillary topics (e.g., innovative item types, assessment engineering, psychometric models, issues surrounding the technology of adaptive testing, validity studies).
  2. Applications and implementations of CAT. These articles include descriptions of specific decisions made for a particular purpose, required by the nature of the adaptive test being developed, including (but not limited to) the nature of the testing population, the type of decisions being made with the information from the test, the size of the available item bank, the changing nature of item styles, approaches to field testing, and complex item selection procedures.

JCAT is the official journal of the International Association for Computerized Adaptive Testing.

Vol. 11 No. 1 (2024): The Influence of Computerized Adaptive Testing on Psychometric Theory and Practice

The major premise of this article is that part of the stimulus for the evolution of psychometric theory since the 1950s was the introduction of the concept of computerized adaptive testing (CAT) or its earlier non-CAT variations. The conceptual underpinnings of CAT that had the most influence on psychometric theory was the shift of emphasis from the test (or test score) as the focus of analysis to the test item (or item score). The change in focus allowed a change in the way that test results are conceived of as measurements. It also resolved the conflict among a number of ideas that were present in the early work on psychometric theory. Some of the conflicting ideas are summarized below to show how work on the development of CAT resolved some of those conflicts.
