Understanding the efficacy of evidence-based reading practices delivered in the Tier 1 (i.e., general classroom) setting is critical to successful implementation of multitiered systems, meeting a diverse range of student learning needs, and providing high-quality reading instruction across content areas. This meta-analysis presents evidence on the effects of Tier 1 reading instruction on the reading outcomes of students in grades 4–12 and a synthesis of effects for students identified as struggling readers. Results from this meta-analysis of 37 publications conducted between 2000 and 2015 reveal significant, positive effects for Tier 1 reading instruction on comprehension and vocabulary outcomes. A synthesis of the results for struggling readers indicates that they maintained or improved reading comprehension over struggling readers receiving typical instruction.
