This book is open access under a CC BY-NC 2.5 license.​​ This book describes the extensive contributions made toward the advancement of human assessment by scientists from one of the world’s leading research institutions, Educational Testing Service. The book’s four major sections detail research and development in measurement and statistics, education policy analysis and evaluation, scientific psychology, and validity. Many of the developments presented have become de-facto standards in educational and psychological measurement, including in item response theory (IRT), linking and equating, differential item functioning (DIF), and educational surveys like the National Assessment of Educational Progress (NAEP), the Programme of international Student Assessment (PISA), the Progress of International Reading Literacy Study (PIRLS) and the Trends in Mathematics and Science Study (TIMSS). In addition to its comprehensive coverage of contributions to the theory and methodology of educational and psychological measurement and statistics, the book gives significant attention to ETS work in cognitive, personality, developmental, and social psychology, and to education policy analysis and program evaluation. The chapter authors are long-standing experts who provide broad coverage and thoughtful insights that build upon decades of experience in research and best practices for measurement, evaluation, scientific psychology, and education policy analysis. Opening with a chapter on the genesis of ETS and closing with a synthesis of the enormously diverse set of contributions made over its 70-year history, the book is a useful resource for all interested in the improvement of human assessment.

This book documents the history of ideas about problem gambling and its link to addictive disorders. The book uses a combination of literature review and conceptual and linguistic analysis to explore the way ideas about problem gambling gave changed over time. It examines the religious, socio-cultural, and medical influences on the development of the concept of problem gambling as a disease, along with the ways in which such ideas were influenced by attitudes about substance abuse. The history of mental illness, notably as it pertains to themes such as loss of control over behavior, is also addressed. The book ends with a discussion of the current status and future prospects, with an eye to which ideas about problem gambling and addictions seem most promising and which should perhaps be left behind.​
