Validity in Educational and Psychological Assessment

'Countless books have addressed validity, but this is the first volume to provide a comprehensive treatment of the evolution of validity theory in the last century and a framework for evaluating educational and psychological testing in the 21^st century.'

'With concerns over the validity of educational and psychological tests and assessments growing, this book by Paul Newton and Stuart Shaw is a welcome, and much needed, contribution to the measurement literature. Anyone concerned with the technical quality and value propositions surrounding large-scale testing and assessment ought to read this book. Newton and Shaw take the reader through the history of "validity" as researchers across time and across disciplines use the term. In doing so, they advance the debate by offering a unique and novel framework for assessing issues of test validity. Newton and Shaw leave us with some new concepts-theoretical plausibility and practical viability-for judging the evidence in support of a test's validity. This book presents today's and tomorrow's perspectives on validity as the core idea in educational and psychological assessment. It is a must read for those working in the broad field of psychometrics.'
