Assessing English proficiency for university study English medium institutions around the world face challenges in coping with the diverse language backgrounds of their students. This book focuses on strategies and procedures for assessing the academic language ability of incoming students so that those with significant needs can have opportunities to enhance their language skills. It draws upon a variety of contexts with a particular focus on initiatives at universities in Australia and New Zealand to introduce post entry language assessment (PELA) programmes. The book discusses the relative merits of the constructs of academic language proficiency and academic literacies as the basis for the assessment and also considers the diagnostic nature of such assessments. On a practical level there is a wealth of advice on appropriate test formats and a framework for evaluating the validity of assessments of this kind. It will be of great interest to academics and administrators concerned with the quality of teaching and learning in their institutions as well as lecturers and tutors in EAP and academic learning programmes
