This book communicates the excitement and dynamics of the field of psychological testing. The authors provide readers with a current analysis of the most widely used psychological tests in schools, professional training programs, business, industry, the military, and clinical settings. As readers progress through the book, they get a clear picture of how psychological tests are constructed, how they are used, and how an understanding of them can make a difference in their careers and everyday lives.

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.

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.
