This volume introduces a new concept, 'criterial features', for the learning, teaching and testing of English as a second language. The work is based on research conducted within the English Profile Programme at Cambridge University, using the Cambridge Learner Corpus. The authors address the extent to which learners know the grammar, lexicon and usage conventions of English at each level of the Common European Framework of Reference (CEFR). These levels are currently illustrated in functional terms with 'Can Do' statements. Greater specificity and precision can be achieved by using the tagged and parsed corpus, which enables researchers to identify criterial features of the CEFR levels, i.e. properties that are characteristic and indicative of L2 proficiency at each level. In practical terms, once criterial features have been identified, the grammatical and lexical properties of English can be presented to learners more efficiently and in ways that are appropriate to their levels.

This volume contains a selection of research papers that were presented at the 15th Annual Language Testing Research Colloquium (LTRC) on the themes of performance testing, and on aspects of communication in relation to cognition and assessment. This edited collection includes contributions reporting research into the testing of speaking and writing, especially in relation to raters, tasks and assessment criteria, contributions exploring the application of various statistical methods in langauge test validation and contributions addressing the issues relating to langauge testing in specific contexts with particular candidate groups. This volume will be of relevance to language testing specialists concerned with the design, development, delivery and validation of performance tests, as well as to academic researchers and graduate students interested in the complex relationship between cognition and assessment.

This book introduces the theoretical and empirical bases for the definition of language learning level in functional 'Can Do' terms for the English Profile Programme, setting out the ambitions of the Programme and presenting emerging findings. The English Profile Programme is an elaboration of the performance level descriptions of the Common European Framework of Reference for Languages (CEFR) that is concerned specifically with the English language. The CEFR has become influential in building a shared understanding of performance levels for foreign language learners. However, there is a considerable gap between the broad descriptions of levels provided, which covers a range of languages and learning contexts, and the level of detail required for applications such as syllabus or test design, which this volume addresses. With its combination of theoretical insights and practical advice, this is a useful work for academics, policy-makers, curriculum designers, textbook writers, postgraduate students and examination board staff.
