The assessment of specific learning disabilities and disorders (SLD) has long been controversial. Definitions, diagnosis and treatments have been vigorously debated for decades, with the use of IQ tests attracting particular controversy. However, in recent times there have been many other new assessment tools devised for measuring intelligence and neuropsychological functioning, extending well beyond the scope of Wechsler's scales. In this cutting-edge survey, an international team of leaders in the field examines the available methods. Many of the contributors are themselves the developers of the most recent assessment tests. The authors of each chapter evaluate the diversity of clinical applications of these new instruments in SLD, and their important implications for educational intervention. The historical context and the underlying neuropsychological and cognitive theory are also expertly examined. This book will be essential reading for any practitioner or trainee dealing with specific learning issues in young people.
