Students need strong literacy skills to succeed in core academic subjects--English, mathematics, science, and social studies--and to be prepared for college and careers. "Reading Apprenticeship"® is a professional development program that aims to help teachers improve their students' literacy skills. The program also aims to improve student social-emotional learning outcomes such as belonging, social awareness, growth mindset, and self-efficacy. "Reading Apprenticeship"® trains teachers to model reading comprehension strategies and help students practice these strategies in their classrooms. This Intervention Brief provides an overview of the full Intervention Report, which summarizes the available evidence on the effects of "Reading Apprenticeship"® on student achievement outcomes in middle and high school. There is moderate evidence that "Reading Apprenticeship"® positively impacted student science achievement and grade point average. [For the Intervention Report, see ED625919.]
