The revised and expanded edition of this bestseller is a comprehensive, easy-to-read resource that explores the theory and practice of ESL assessment. Written for anyone working with English-language learners (elementary and secondary, mainstream and ESL), this new edition of Assessment and ESL presents ideas and tools for alternative assessment. The authors offer methods of documenting the learning and progress of second-language learners-learning and progress that may not always be apparent at first glance. Like the previous edition, the new edition is filled with real stories about students who take baby steps, progress in leaps and bounds toward proficiency, and eventually learn to fly on their own.
