This publication highlights the need for test developers to provide clear explanations of the ability constructs which underpin tests offered in the public domain. An explanation is increasingly required, if the validity of test score interpretation and use are to be supported both logically, and with empirical evidence. The book demonstates the application of a comprehensive test validation framework which adopts a socio-cognitive perspective. The framework embraces six core components which reflect the practical nature and quality of an actual testing event. It examines Cambridge ESOL writing tasks from the following perspectives: Test Taker, Cognitive Validity, Context Validity, Scoring Validity, Criterion-related Validity and Consequential Validity. The authors show how an understanding and analysis of the framework and its components in relation to specific writing tests can assist test developers to operationalise their tests more effectively, especially in relation to criterial distinctions across test levels.

Lecturers, request your electronic inspection copy to review it for your course. 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.
