Abstract
<jats:title>Abstract</jats:title> <jats:p>The fifth edition of Educational Measurement represents the first version of this volume produced solely by the National Council on Educational Measurement. This volume, like the previous four editions, provides cutting-edge research and guidance on all major topics in the field of measurement science, with chapters written by acknowledged experts in their respective fields. Edited by Linda L. Cook and Mary J. Pitoniak, the volume is focused on the traditional Educational Measurement audience—those with advanced degrees in the science of measurement, including academics, researchers, and graduate students—but is also accessible and of use to scholars with advanced degrees in related fields and to those who set policy or make decisions that impact the use of educational measurement. The fifth edition contains 21 chapters separated into four parts. Part I provides a framing chapter for the volume, as well as chapters on the history and social context of educational measurement. Part II addresses the important topics of validity, reliability, and fairness theory and concepts. Part III includes new theories and technical advances in topics such as technology-based assessment; scaling, equating, and linking; test administration and scoring; standard setting; modeling educational assessment data; score reporting; fairness and accessibility; and designing and developing assessments. Part IV includes chapters on assessment to inform instruction and learning, test-based accountability in K–12 testing, testing in higher education, licensing and certification assessment, testing of interpersonal and intrapersonal skills, and large-scale assessment in international contexts. Part V provides an extensive discussion on the nature of measurement.</jats:p>
