Despite recent progress in reading achievement among children in primary grades, many children are not moving beyond basic decoding skills to fluency and comprehension as they go on to higher grades. To address this problem, many policymakers suggest that reading coaches -- master teachers who offer ongoing on-site instructional support for teachers -- can improve teachers' practice and students' literacy skills. RAND researchers evaluated the middle school reading coach program in Florida to answer these questions: How is the program being implemented by the state, districts, schools, and individual coaches? What is the impact of coaching on teachers' practice and students' achievement in reading and mathematics? What features of reading coach models and practices are associated with better outcomes? This document provides a summary of that research report. [For full report, see ED502636.]
