This annotated bibliography updated from a 2007 edition, is intended as a resource for technical assistance providers as they work with states on adolescent literacy. This revision includes current research and documents of practical use in guiding improvements in grades 4-12 reading instruction in the content areas and in interventions for struggling readers. It is organized into four categories aligned with information provided in adolescent literacy guidance documents previously developed by the Center on Instruction: Policy and Leadership, Assessment for Instruction, Academic Literacy in the Content Areas, and Interventions for Struggling Readers.
