The issue of high-level language proficiency in other than monolingual contexts can be approached from a variety of perspectives, including linguistic/structural; psycholinguistic/cognitive and sociolinguistic/societal. Bringing together a team of experts, this volume takes a novel empirical approach to the subject combined with an up-to-date understanding of these research areas, to answer two important research questions in the field of second language acquisition: what conditions allow learners to attain an outstanding level of proficiency in a second language, and what factors still prevent them from becoming entirely like first language speakers. Looking at a range of European languages including English, French, Italian, Spanish and Swedish, it provides important insights into second language use at the highest levels as well as in high-proficient mixed language use in multicultural settings. A useful tool for both language teaching and language teacher training, it provides a solid grounding for further study in this important area of research.

The Common European Framework of Reference for Languages (CEFR) has become the yardstick for teaching and testing language skills in Europe and elsewhere. Yet little is known about the relationships between the communicative levels established using the can-do statements of the CEFR and the developmental stages of grammatical and lexical development described by Second Language Acquisition (SLA) research. This book presents empirical research by members of the SLATE network (Second Language Acquisition and Testing in Europe), aimed at bridging this gap. The studies deal with several target languages, including Dutch, English, Finnish, French, Italian, Norwegian and Spanish, with adult, adolescent and child learners in both formal and informal contexts.
