This book aims to empower multilingual learners, families, and teachers. With its emphasis on relationship building as the backdrop for linguistically and culturally sustainable assessment, the bestselling previous edition significantly impacted the field of language education. Applying the groundbreaking assessment "as," "for," and "of" learning model to new contexts, this updated edition offers educators welcoming and encouraging ways to support multilingual learners to succeed in school and beyond. Through eight thoroughly revised chapters, the author ties assessment to teaching and learning to foster agency and empowerment for multilingual learners, families, and teachers. This book envisions assessment as a process integral to and embedded in curriculum and instruction through assets-based language, student-centered activities; classroom assessment tools; portraits of practice illustrating authentic assessment practices; references and resources for stimulating discussion; and deep questioning for thinking through processes, dilemmas, or challenges. This volume explores the realities and possibilities of classroom assessment as a road to inspire multilingual learners, their families, and teachers to reach great heights.
