About
Lexia Learning is an evidence-based reading and literacy company that provides adaptive blended learning programs for K-5 students, with a strong emphasis on structured literacy — the systematic, explicit approach to teaching foundational reading skills supported by decades of research in the science of reading. Headquartered in Concord, Massachusetts, Lexia was acquired by Rosetta Stone and is now part of the IXL Learning portfolio. The company's flagship product, Lexia Core5 Reading, is among the most research-validated adaptive reading programs in K-5 education, with multiple independent studies demonstrating learning gains for students across reading ability levels.\n\nLexia Core5 provides individualized reading instruction that assesses students' phonological awareness, phonics, fluency, vocabulary, and comprehension, and delivers targeted instruction in each area through an engaging game-like interface. The program adapts continuously to each student's responses, providing more support in areas where students struggle and accelerating through skills that students demonstrate mastery of. For teachers, Lexia provides detailed data dashboards showing each student's progress in each foundational skill area, along with specific recommendations for targeted small-group and one-on-one instruction.\n\nLexia differentiates from other reading platforms through its depth of alignment to the science of reading and structured literacy principles, which have gained significant policy attention as states across the US mandate evidence-based reading instruction. The company also offers Lexia LETRS, a professional development program for teachers in the science of reading, extending its reach to teacher training. Lexia competes with i-Ready, Waterford, Amplify Reading, and other foundational literacy programs for its core elementary market.
