Going into its eighth edition, this book is a classic in the field of educational measurement. It was written from the point of view of the classroom teacher to answer the question, "What does a teacher need to know about the development and evaluation of educational measures and assessments?" This book fosters an understanding of how assessment and instruction are interrelated. It also cultivates learning the techniques and skills needed to develop tests and other evaluation procedures (e.g. portfolios), as well as teaches students to understand how to evaluate the validity and reliability of tests. Unlike many books in educational measurement, this book also gives readers what they need to know to properly interpret the results from standardized achievement and scholastic aptitude tests. Topics include: test reliability and validity; meaning and application of the norms; extraneous factors that influence performance of cognitive tests; the development of educational measures; and more. Teachers, principals, and counselors.

This edition continues Sax's tradition of comprehensive and comprehensible coverage of testing and measurement principles while including the most recent theory and research.

This new text provides the most current coverage of measurement and psychometrics in a single volume. Authors W. Holmes Finch and Brian F. French first review the basics of psychometrics and measurement, before moving on to more complex topics such as equating and scaling, item response theory, standard setting, and computer adaptive testing. Also included are discussions of cutting-edge topics utilized by practitioners in the field, such as automated test development, game-based assessment, and automated test scoring. This book is ideal for use as a primary text for graduate-level psychometrics/measurement courses, as well as for researchers in need of a broad resource for understanding test theory. Features: "How it Works" and "Psychometrics in the Real World" boxes break down important concepts through worked examples, and show how theory can be applied to practice. End-of-chapter exercises allow students to test their comprehension of the material, while suggested readings and website links provide resources for further investigation. A collection of free online resources include the full output from R, SPSS, and Excel for each of the analyses conducted in the book, as well as additional exercises, sample homework assignments, answer keys, and PowerPoint lecture slides.

Validity is the hallmark of quality for educational and psychological measurement. But what does quality mean in this context? And to what, exactly, does the concept of validity apply? These apparently innocuous questions parachute the unwary inquirer into a minefield of tricky ideas. This book guides you through this minefield, investigating how the concept of validity has evolved from the nineteenth century to the present day. Communicating complicated concepts straightforwardly, the authors answer questions like: What does ′validity′ mean? What does it mean to ′validate′? How many different kinds of validity are there? When does validation begin and end? Is reliability a part of validity, or distinct from it? This book will be of interest to anyone with a professional or academic interest in evaluating the quality of educational or psychological assessments, measurements and diagnoses.
