The ongoing literacy crisis in the U.S. highlights an urgent need for effective, scalable literacy instruction. REED Charitable Foundation (RCF) is a non-profit organization that provides structured literacy training informed by Orton-Gillingham, along with ongoing professional coaching and comprehensive implementation support to help all students learn to read. RCF Model Schools are whole schools that receive this comprehensive training and implementation support designed to provide all aspects of structured literacy instruction. The current correlational study evaluates the RCF Model School approach in 3 schools with over 1500 students across two years of implementation, 2022-2024. Results demonstrate substantial literacy growth for students in RCF Model Schools, with gains that increase as implementation progresses. Results indicate that first and second graders in Year 2 of implementation achieved literacy growth that significantly exceeded national growth norms, and there was a cumulative impact of multi-year implementation across grades. In addition, more students met or exceeded the proficiency benchmark by the end of the year, with students who started in the lowest percentile ranks making the greatest gains. By fostering an environment of ongoing professional learning and job-embedded support, RCF Model Schools appear to provide the robust support system that teachers need to enhance student achievement year after year.
