The "School Leader's Literacy Walkthrough" is designed to assist school leaders in observing specific research-based practices during literacy instruction (or students' independent use or application of those practices). This tool is based on rigorous research that indicates the most effective way to teach reading (see Foorman & Connor, 2011, and Foorman & Wanzek, 2015, for reviews) and is aligned to contemporary state standards. This tool is not meant to be used in the evaluation of teachers. Instead, the tool is intended to help school leaders enhance literacy instruction knowledge, communicate with teachers their expectations about literacy instruction, and establish consistent language regarding literacy content and instructional strategies. Further, the use of this tool can be the basis of productive communication and collaboration among school leaders and teachers and inform professional learning needs to improve student achievement in literacy.
