In this guide, the author presents guidelines for analyzing spoken and written language production in adolescents in middle and high school who have a language disorder. She addresses conversational, narrative, expository, and persuasive language samples and how to use information from analysis to understand how teens communicate in natural settings and also promote their language development. She describes the benefits of language sampling, its history, adolescent language development, sampling guidelines, tasks, and interventions, and reviews grammar (with exercises). This edition includes revised and updated content and two new chapters on autism spectrum disorders and language samples from different genres from adolescents with typical language development.
