Based on a tremendous increase in the development of psychometric theories in the past decade -- ranging from techniques for criterion-referenced testing to behavioral assessment, generalizability, and item response theory -- this book offers a summary of core issues. In so doing, it provides a comprehensive survey of reliability, validity, and item analysis from the perspectives of classical true-score model, generalizability theory, item response theory, criterion-referenced testing, and behavioral assessment. Related theoretical issues such as item bias, equating, and cut-score determination are also discussed. This is an excellent text for courses in statistics, research methods, behavioral medicine and cognitive science as well as educational, school, experimental, counseling/social, clinical, developmental, and personality psychology.

Winner of the British Psychological Society's Textbook Award 2019. Psychological tests are everywhere. They are widely used by practitioners, researchers, clinicians, and educators -anyone, in fact, who needs to measure various aspects of personality, cognitive abilities, mood and suchlike. Psychometrics is the science of psychological assessment. It covers the construction, use and interpretation of psychological tests of all kinds – from simple questionnaires measuring personality, moods and attitudes, through to specialised tests measuring IQ and other mental abilities. Psychological Testing: Theory and Practice provides test users, test developers, practitioners and researchers in the social sciences, education and health with an evaluative guide to choosing, using, interpreting and developing tests. Its aim is to give readers a thorough grasp of the principles (and limitations) of testing, together with the necessary methodological detail. Unusually for an introductory text, it includes coverage of several cutting-edge techniques. If you find mathematics frightening and statistics dull, this engaging text will help you to understand the fundamental principles of psychometrics, that underpin the measurement of any human characteristic using any psychological test. The book is accompanied by additional resources, including a set of spreadsheets which use simulated data and other techniques to illustrate important issues, and allow users to understand various statistical procedures work, without getting bogged down in mathematical detail. These are fully integrated into the text. This is an essential introduction for all students of psychology and related disiplines, as well as a useful resource for practitioners and those seeking accreditation in psychological testing.

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.

In one volume, this authoritative reference presents a current, comprehensive overview of intellectual and cognitive assessment, with a focus on practical applications. Leaders in the field describe major theories of intelligence and provide the knowledge needed to use the latest measures of cognitive abilities with individuals of all ages, from toddlers to adults. Evidence-based approaches to test interpretation, and their relevance for intervention, are described. The book addresses critical issues in assessing particular populations—including culturally and linguistically diverse students, gifted students, and those with learning difficulties and disabilities—in today's educational settings. New to This Edition*Incorporates major research advances and legislative and policy changes.*Covers recent test revisions plus additional tests: the NEPSY-II and the Wechsler Nonverbal Scale of Ability.*Expanded coverage of specific populations: chapters on autism spectrum disorders, attention-deficit/hyperactivity disorder, sensory and physical disabilities and traumatic brain injury, and intellectual disabilities.*Chapters on neuropsychological approaches, assessment of executive functions, and multi-tiered service delivery models in schools.

The editors of this volume suggest that there are missing elements in the conceptualization upon which standard test theory is based. Those elements are models for just how people know what they know and do what they can do, and the ways in which they increase these capacities. Different models are useful for different purposes; therefore, broader or alternative student models may be appropriate. The chapters in this volume consider a variety of directions in which standard test theory might be extended. Topics covered include: the role of test theory in light of recent work in cognitive and educational psychology, test design, student modeling, test analysis, and the integration of assessment and instruction.

As part of their research activities, researchers in all areas of education develop measuring instruments, design and conduct experiments and surveys, and analyze data resulting from these activities. Educational research has a strong tradition of employing state-of-the-art statistical and psychometric (psychological measurement) techniques. Commonly referred to as quantitative methods, these techniques cover a range of statistical tests and tools. Quantitative research is essentially about collecting numerical data to explain a particular phenomenon of interest. Over the years, many methods and models have been developed to address the increasingly complex issues that educational researchers seek to address. This handbook serves to act as a reference for educational researchers and practitioners who desire to acquire knowledge and skills in quantitative methods for data analysis or to obtain deeper insights from published works. Written by experienced researchers and educators, each chapter in this handbook covers a methodological topic with attention paid to the theory, procedures, and the challenges on the use of that particular methodology. It is hoped that readers will come away from each chapter with a greater understanding of the methodology being addressed as well as an understanding of the directions for future developments within that methodological area.
