"Educational Measurement" has been the bible in its field since the first edition was published by ACE in 1951. The importance of this fourth edition of "Educational Measurement" is to extensively update and extend the topics treated in the previous three editions. As such, the fourth edition documents progress in the field and provides critical guidance to the efforts of new generations of researchers and practitioners. This fourth edition provides in-depth treatments of critical measurement topics, and the chapter authors are acknowledged experts in their respective fields. Educational measurement researchers and practitioners will find this text essential, and those interested in statistics, psychology, business, and economics should also find this work to be of very strong interest. This book is divided into three parts and 21 chapters. Following the first chapter, Perspectives on the Evolution and Future of Educational Measurement (Robert L.
