RESEARCH INTEGRATION REPORT: Early Evidence Establishing the Efficacy of Lexia Programs

This Integration Report provides an overview of early research studies that examined the impact of products that were precursors to Lexia® Core5® Reading and Lexia® PowerUp Literacy®. These products included Early Reading, Phonics Based Reading, Primary Reading, and Strategies for Older Students. The studies reviewed in this report were conducted by Lexia® researchers, as well as external researchers. Most employed randomization methods comparing treatment and control conditions. The studies showed positive outcomes of the products for various subgroups of students, including students in preschool through first grade, students identified as low performers and English Learners. Overall, these studies demonstrate the efficacy of Lexia’s precursor products and point to the strong evidence base upon which Core5 and PowerUp were built.
