There are many circumstances under which both children and adults need to have their literacy skills assessed. This book provides comprehensive guidance for all those involved in the assessment process, outlining the pitfalls and suggesting best practices. The first part of the book contains chapters outlining the main theoretical postions, including a discussion of dsylexia and the assessment of different aspects of reading including phonological skills, comprehension, spelling and written expression, adult's problems, acquired reading disorders and the legal aspects of reading assessment. A final section contains reviews of the most widely used and useful tests available. A reference tool for professionals in educational and clinical settings, this book should prove an important text for students and trainees.
