A state-of-the-art overview of the critical areas of language assessment The dynamic field of language assessment has a tangible impact on the lives of language learners. Consequently, modern assessment approaches must continue to evolve to meet the needs of first- and second-language learners in our increasingly globalized world. The Concise Companion to Language Assessment combines newly commissioned articles on recent innovations in assessment with an expertly curated selection of chapters from The Companion to Language Assessment, the landmark four-volume reference work first published a decade ago. Organized around eight themes, The Concise Companion examines a broad range of language assessment topics, from fundamental assessment methods to cutting-edge AI implementations. In forty-five chapters, both established and newer scholars discuss assessment conceptualization, development, research, and policy, as well as developments in independent and integrated language skills assessment, learning-oriented assessment, teacher-based assessment, assessment for immigration and citizenship, and psychometric and technological contributions to assessment. Addressing multiple assessment environments, including classrooms, universities, employment, and Immigration and citizenship, The Concise Companion to Language Assessment is an ideal textbook for undergraduate and graduate courses and researchers and policy makers in applied linguistics, language assessment, TESOL, second language acquisition, and language policy.
