Routledge Applied Linguistics is a series of comprehensive textbooks, providing students and researchers with the support they need for advanced study in the core areas of English language and Applied Linguistics. Each book in the series guides readers through three main sections, enabling them to explore and develop major themes within the discipline. Section A, Introduction, establishes the key terms and concepts and extends readers’ techniques of analysis through practical application. Section B, Extension, brings together influential articles, sets them in context, and discusses their contribution to the field. Section C, Exploration, builds on knowledge gained in the first two sections, setting thoughtful tasks around further illustrative material. This enables readers to engage more actively with the subject matter and encourages them to develop their own research responses. Throughout the book, topics are revisited, extended, interwoven and deconstructed, with the reader’s understanding strengthened by tasks and follow-up questions. Language Testing and Assessment: introduces students to the key methods and debates surrounding language testing and assessment explores the testing of linguistic competence of children, students, asylum seekers and many others in context of the uses to which such research can be put presents influential and seminal readings in testing and assessment by names such as Michael Canale and Merrill Swain, Michael Kane, Alan Davies, Lee Cronbach and Paul Meehl, and Pamela Moss.
